Varicose Veins are abnormally thick veins that are twisted and enlarged. This problem occurs mostly in the leg and thigh veins. The thickened and twisted veins are called varicose veins. They can occur anywhere, but they mostly form in the legs because the legs work against gravity. Standing all day can increase the pressure on leg veins and cause varicose veins. Causes The normal function of veins is to carry blood from the outer body parts to the heart and lungs. The veins are provided with one-way valves, which prevent the blood from flowing backward within the vein. Defective or damaged valves are the main reason for varicose veins, as they allow the blood to flow backward, when it should be actually flowing up towards the heart. As the muscles contract to empty the veins, pressure builds up and this causes in the flow of more blood in the wrong way. Thus the pressure on the veins is increased and this causes varicose veins. Factors that Aggravate Varicose Veins
Treatment There are different types of treatments available to shrink varicose veins and to improve circulation, from simple home remedies to surgeries or medications for severe cases. Natural supplements like Butcher's broom are considered to be a very effective treatment for varicosities. Butcher's Broom Butcher's broom is a small, clump-forming evergreen shrub with tiny green flowers. It is an aromatic, diuretic and mildly laxative herb that helps reduce inflammation, increase perspiration and constrict the veins. The whole plant, young shoots and roots are used medically. Young shoots can be eaten like asparagus. It grows commonly in woodlands and hedgerows, and also on coastal cliffs. It is widely grown from Iran to the Mediterranean and the United States. Its scientific name is Ruscus aculeatus, but it is commonly known as butcher's broom because butcher's used the stiff twigs to clean their cutting boards. The herb has been used for nearly 2000 years, but its medicinal uses have become common only from the last century. Investigations conducted in the 1950s indicated that butcher's broom can induce vasoconstriction and thus might be useful in treating circulatory diseases. How It Works? The two primary chemicals in butcher's broom, ruscogenin and neoruscogenin, can cause the blood vessels to narrow or constrict. Their anti-inflammatory properties help improve blood circulation in legs by preventing pooling of blood and reduce swelling.
Therapeutic Uses Butcher's broom is used internally to treat venous problems that vary from varicose veins to hemorrhoids. It is also used to strengthen the veins and capillaries. Butcher's broom may be the best natural solution for varicose vein treatment, because it helps with blood flow and circulation.

Blood vessels can be found all over the body. It is the passageway of blood so that cellular oxygenation as well as elimination of harmful substances from the cells would be successful. Blood vessels have three types, namely the arteries, the veins and the capillaries. Arteries contain the blood from the pulmonary system which is highly oxygenated while the veins consist of blood which is deoxygenated and abundant in cellular waste. Capillaries serve as a bridge between the two major blood vessels. Among these blood vessels, the veins are the only of its kind which has valves. These valves prevent backflow of blood since the direction of the blood in the vein is against gravity. Therefore, it is of no surprise that among the three types of blood vessels, veins are the most commonly damaged. In this article, we will be discussing of natural ways or herbs which are effective as vein strengtheners. 1. HORSE CHESTNUT. Traditionally, this herb has been used for the improvement of health the veins. In fact, Western medicine has considered this herb as the most effective herbal medicine for venous problems most especially Chronic Venous Insufficiency. It can improve venous return by improving the ability of the valves of veins to return blood to the heart from the lower extremities. This herb has also been found to decrease permeability of the capillary wall permeability thus lessening fluid outflow into tissues. The recommended dosage for this supplement is 500 mg each morning. 2. GOTU KOLA. Gotu kola is a popular herbal medicine of the Indian Ayurvedic medicine. It is also considered to be one of the oldest herbal medicines all over the world. This herb has been found to be effective in improving the tone, flexibility and integrity of the blood vessels. Therefore, this herb has been long used as a treatment for circulatory problems most especially varicose veins. 200 milligram extract of this herb is usually suggested three times daily. 3. RUTIN. This is not an herb itself but a chemical substance which can be found in several plants. Rutin is considered to be a flavonoid which can be extracted from citrus peels, cranberries, asparagus and buckwheat. Clinical studies of this chemical compound have revealed that it be an effective relief treatment of damaged and edematous veins. This chemical can also be used for improving the strength of the capillaries thus lowering the risk of damage. These are only some of the herbs which are found to be effective as vein strengtheners. These herbs can be made into a poultice and applied to the skin so that positive effect can be obtained. Along with these herbs, it is also important that you should exercise regularly. Elevate your legs, if possible, especially when lying down at hours of sleep. This would greatly help in promoting venous return thus thwarting blood pooling at the lower extremities. It is also important that you should avoid long time standing or sitting. Health experts also suggest that people must avoid prolong crossing of legs and not to wear tight clothing and foot wears since this can possibly constrict veins..

Over 12 million people suffer from varicose veins in the US alone, and leg veins in particular are expected to appear by the time women turn 50. There is nothing pleasant about having varicose veins, and complications are not uncommon, giving rise to venous ulcers and even cancerous tissues. The good news is that a treatment proven to be safe and effective has been around for years with the use of horse chestnut seed extract or HCSE as made available by pharmaceutical companies. Veins may develop conditions leading to the impairment of its functions. Unlike arteries, veins pump blood back to the heart, and acting against gravity bear the weight of the blood coming from the lower extremities. This seems to be a real burden to the veins in the legs, but the vascular walls of all veins have special valves to accomplish this feat. To avoid blood flow moving against the programmed current inside the veins, leaflets of the valves fold and close up as blood passes. A medical condition called chronic venous insufficiency explains the appearance of varicose veins. Veins anywhere in the body can get inflicted with the same symptoms made evident by varicose veins, but the latter is more noticeable because it lies close to the surface of the skin. The valves inside the venous system must be able to act against the turbulence that may occur inside the tube, and when they don’t, blood flow literally descends into chaos, putting an added pressure on the vascular walls. The resulting dilated veins are what we refer to as varicose veins, which is just one symptom of chronic venous insufficiency. Age is one major factor in the development of this medical condition. It is a fact that the valves inside the leg veins are more susceptible to decreasing elasticity as we age due to daily wear and tear the veins in the legs has to endure over the years. Since female hormones contribute to the relaxing of the vascular walls, varicose veins are more likely to afflict women. For most women, varicose veins must be remedied to avoid the social implications they bring. However, there are a number of patients that are plagued with a variety of complications. Some women practically lose the ability to stand or walk for otherwise short stretches of time, significantly affecting their productivity at work. More severe cases include the formation of skin ulcers close to the area of varicose veins, which may worsen into necrosis or skin loss. All the debilitating effects of varicose veins can be countered by intake of horse chestnut seed extract, including of course the removal of ugly leg veins. Standardized dosage of horse chestnut is among the best remedies for chronic venous insufficiency, accounting for innumerable positive results that have been documented in recent years minus the side effects commonly associated with other medications. In fact, medical professionals in Europe largely rely on the use of horse chestnut to correct varicose veins.

To fight off aging you have to understand what causes it, and the take steps to avoid these causes. It is fairly obvious that all causes of aging cannot be circumvented, but there are things that can be done to keep some of them at bay. Here, we are specifically concerned with the aging of your skin, which is the most visible form of aging. The first aspect of aging to understand is that there are two types: intrinsic and extrinsic. Intrinsic Aging Intrinsic aging is natural aging, and is largely genetic. Starting when you are fairly young, normally in the early to mid 20s, intrinsic aging is typified by wrinkling, hair loss or graying of the hair, hollowing of cheeks and other areas where the fat underneath the skin that normally contributes to your physical appearance is lost, and also bone loss that causes your skin to sag due a gradual loss of the structure that sculpts your physical appearance. The age at which this occurs, and its speed is determined by your genes; although the process generally begins around the mid 20s, the speed with which it progresses is genetically controlled. Extrinsic Aging This is where grape seed extract can help. Extrinsic aging is not genetic, but environmental. Ten majority of this type of aging is due to exposure to the damaging UV light of the sun, which cause the typical 'leathery' look of the skin of people raised in areas such locations as the hotter parts of Australia and the USA, without the benefit of the native skin pigmentation that filters out these harmful ultra-violet rays. Other factors that can cause the same degradation of your skin cells are smoking, the way you sleep and gravity. The sun generates free radicals (more on these later) that can destroy skin cells, cause freckles, leathery skin and a blotched complexion and also skin cancer. Smokers are more likely to develop leathery and wrinkled skin than non-smokers, and as the elasticity of your skin reduces, gravity cause jowls to develop and also a more pronounced lower lip. Even your sleeping position can make you appear to age quicker, particularly using the same sleeping position on your pillow each night that cause what are known as sleep lines, that are really wrinkles that are difficult, if not impossible to remove. However, one of the most relevant factors is pollution, and the effects of car emissions, pesticides and other agricultural chemicals, paint fumes and 1001 other forms of chemical pollution that produce free radicals. Where grape seed extract is involved in fighting off aging is in extrinsic aging is by destroying the free radicals. All substances, from the air to the oceans, are formed of atoms that contain electrons. Stable molecules contain an even number of electrons, or what are known as 'electron pairs'. When a molecule loses one electron it is known as a free radical, whose prime purpose in its very short life is to steal an electron from the nearest molecule. This 'short' lifetime can as long as a day or as short as thousandth of a second: it depends on is size and the degree of steric hindrance to the reaction with the spare electron. Now that the reasons for aging and the nature of free radicals are better understood it is easier for you understand why grape seed extract can help to fight aging caused by the effects of free radicals on your skin. Grape seed is a waste product of the wine industry. You cannot make wine from grape seeds, so they are removed from the final product by filtration or sedimentation. It contains a large number of phytonutrients, the most important being polyphenols in the form of flavanoids, lipids and carbohydrates. It also contains proteins that don't have much of an effect on aging. Flavonoids (also spelled flavanoids) are powerful antioxidants that destroy free radicals; they are twenty times as powerful as Vitamin E and over fifty times more powerful an antioxidant than Vitamin C. Both of these vitamins are regarded as strong antioxidants in their own right, which is an indication of how good grape seed extract is at killing free radicals. It's like a combination of Harry Callahan, Paul Kersey, John McClane and the whole of the Magnificent Seven after the scavengers in your body cells. They succeed, and do it in spades! Not only do the ingredients of grape seed extract kill off free radicals with the efficiency of a Delta Task Force, but are also anti-allergenic, anti-inflammatory, anti-cancer and anti just about anything else you can think of. However, let's have an even closer look and find out exactly what polyphenols are present in this so-called wonder juice. Procyanadin was originally named Vitamin P in 1936 by its discoverer, Prof. Jacques Masquelier, and is believed to bond with collagen to protect you from premature aging by retaining and even improving the elasticity of your skin. An added benefit is that it also improves the elasticity of your blood vessels, and so helps to fight off the effects of high blood pressure and places less strain on your heart. The overall effect on your face is to practically give you a chemical face lift and also provide protection from the damaging effect of the UV component of sunlight through its lethal attitude towards the free radicals that UV radiation generates. Another component of grape seed extract particularly that of muscadine grapes is resveratrol; a phytoalexin that has strong anti-inflammatory properties and can also fight off the effects of aging. Phytoalexins are antibiotics produced by plants that are under attack, and, in addition to helping you age slower, confers other benefits to your body including helping your brain to carry out its work more efficiently.
All in all, grape seed extract confers many benefits to your health and is also believed to possess powerful anti-cancer properties. However, it is for its ability to fight off aging that most people use it as a supplement, and in this respect it has been found to be extremely effective. Any antioxidant is of benefit to your body, but grape seed extract is of particular benefit due its high antioxidant potency.

May 02, 2008 11:04 AM
Butcher’s broom (Ruscus aculeatus) is a member of the lily family, and looks a bit like a holly bush with barbed evergreen leaves and bright red berries in the fall. At one time they were collected, tied together and sold to butchers as brooms to sweep out their shops. The stiff leaves were particularly suitable for cleaning out offal and other waste products from butchered animals and also for scrubbing butcher’s blocks. It was also used as a deterrent to rodents with their eyes on the meat! Alternative names are sweet broom, kneeholy and Jew’s myrtle, so named because it was used during the Feast of the Tabernacles as one of the ‘four species’ used in the lulav. The herb was commonly used in Ancient Greece and Rome, the Greeks using it to reduce swellings of various kinds and the Romans using it to treat varicose veins. It has the same uses today, only the mechanisms are understood better. It has been used for centuries in the Mediterranean area for the treatment of inflammations and problems with the circulation, and the Romans used to mash up the leaves and berries to add to wine, and they also used the roots and rhizome as a medicine by soaking them in wine. Today, it is illegal to use holly as a decoration in Italy, so butcher’s broom is used instead. All parts of the plant are used, including the rhizome, and although it is used as a diuretic, and to control a loss of blood pressure experience by some people on standing up, it is its effect on blood vessels where its main medical benefits lie. Butcher’s Broom can strengthen certain portions of blood vessels, and change the flexibility properties of the cell walls. The result of this is that the vessels are tightened up, which helps to maintain the flow of blood throughout the body, but also renders the cell walls less likely to leak or crack under stress. The result is a reduction in blood leakage from stretched and weakened blood vessels such as those that result in hemorrhoids, and also of conditions caused by weakened valves in the veins such as varicose veins and spider veins. The blood pressure in the veins is very weak since they are so far away from the heart, the blood having passed through the arteries, through the capillaries and into the veins on its way back to the heart before being pumped to the lungs. When the valves become weakened, particularly in the large veins in the leg, there is little to prevent the blood from coming under the influence of gravity and pooling back down the vein, causing distention and occasional ruptures. A ruptured varicose vein can be very serious and cause significant blood loss. Weakened valves can also lead to the formation of blood clots, which is itself a very serious condition that eventually blocks the heart or causes a stroke. Not only can butcher’s broom strengthen the vein walls and prevent leakage, and also enable them to more easily resist the pressure that can cause them to rupture, but it can also be used to break down blood clots. In fact the herb is used in many European hospitals to prevent the formation of blood clots after surgery. The active ingredients in the rhizome are saponins that contain the aglycones ruscogenin and neuroscogenin and the associated spirostanol and furostanol glycosides. The receptors that cause vasocontraction are known as adrenoreceptors, these receptors can be selectively stimulated by butcher’s broom extract to tighten the veins and improve the return of blood. When introduced intravenously, butcher’s broom was noted to constrict venules (small veins that feed the main veins but not arterioles (the small arteries than feed the capillaries). Hence blood vessels can be selectively treated, and the effect on isolated blood vessels was enhanced by heating. Many supplements include calcium that helps to strengthen the blood vessel walls. It is possible, therefore, to target the blood vessels that require constrictive treatment in order that they are strong enough to return blood to the heart rather than leak or distend. However, that is not the only health benefit that butcher’s broom provides. It can also be used as a diuretic. It is not a strong diuretic, but is used to relief the swelling of bruises and PMS, the reason given being that since leakage from the blood vessels is lessened, then more fluid is available to pass through the kidneys. There might be other reasons. It is also use for the treatment of ortho static hypotension, the reduction in blood pressure that some people experience. It is believed that butcher’s broom can control this condition without increasing blood pressure, as most other remedies do, and which is almost as undesirable as the condition they are treating. There are few problems associated with the herb, although few studies have been carried out its use by pregnant women. Although the one test that was carried indicated no effect, it would be wise for pregnant or nursing women not to use it until further studies have been carried out. Due to its effect in tightening blood vessels, its use is not recommended by anybody suffering from high blood pressure (hypertension). Many hypertension treatments are designed to render the blood vessels more elastic rather than constrict them. In one very small study of pregnant women who used a topical cream containing butcher's broom, no side effects were seen for either the mother or the baby. However, very little information is available on how oral butcher's broom might affect a developing fetus, an infant, or a small child. Therefore, its use is not recommended during pregnancy, while breast-feeding, or during early childhood. Because it tightens blood vessels, butcher's broom may worsen high blood pressure or benign prostate hyperplasia (BPH). Individuals with either of these conditions should not use any form of butcher's broom without first consulting a doctor. The known side effects have already been stated, and they are fairly mild, but few studies have been made on the herb other than in Europe, and the side effects have not been fully explored. It is unlikely; however, that there are any as yet unknown serious side effects since butcher’s broom has been used now for a long time, particularly in Europe.
The term ‘ruscogenin’ is used for the collective mixture of active saponins in butcher’s broom, and many of the supplements are formulated to include from 5 to 15 mg of these. However, check the label, since standardization is not yet required in the USA, and in theory a preparation can include much more or much less ruscogenin. It is frequently supplied with other active ingredients, such as vitamin C or calcium, and perhaps even horse chestnut that affect blood vessels in a similar way. Always follow the instructions on the package, since these are designed for the specific strength of supplement you are using.

Essential Oil FAQ'sWhat are essential oils?Essential Oils are the naturally occurring volatile oils obtained by distillation or expression having the characteristic aroma of the plant part from which it was derived. These 100% pure oils are neat, meaning they have not been processed or manipulated in any way with solvents or other additives. Though a particular species of plant harvested and distilled for its essential oil during a particular growing season in a specific region may produce a fragrance that differs from the same species grown that season in a different region, many of the main chemical markers and physical specifications may be similar. Do essential oils have a grading system to tell me which is better? There are many companies selling Essential Oils today spinning many tall tales regarding the quality or grade of their products. To my knowledge there exists NO official grading system in any of the more respected sources of essential oil literature. Neither The Federal Register and Code of Regulations, FEMA nor AFNOR has to date adopted a system that grades these oils as an A, B or C grade. A product is either 100% pure essential oil or it’s not. All of our 100% pure essential Oils are labeled as such. We also sell oil blends that are formulated with essential oils or absolute extracts and pure grapeseed oil and are clearly labeled. Are NOW essential oils pure or do they have anything added to them? Again all of our 100% pure essential Oils are labeled as such. We also sell oil blends that are formulated with essential oils or absolute extracts and pure grapeseed oil and are clearly labeled. Natural Essential Oils by their very definition will vary from season to season. We are committed to allowing nature take its course without adding isolated compounds to the oil in an effort to improve on the naturally occurring nuance. We take both the organoleptic (sight, smell and taste) and chemical properties into account when evaluating our essential oils. What are NOW’s criteria for testing essential oils? Our Quality Assurance and Control departments adhere to specifications used by the Essential Oils and Flavor Industry and published in The Essential Oils by Guenther, as well as Fenaroli’s Handbook of Flavor Ingredients. These texts, as well as other sources of scientific information, detail specific physical and chemical properties that compose a fingerprint defining the peculiarities of a particular oil. A partial list of the components that we analyze for would include Specific Gravity, Refractive Index, Optical Rotation, Flash Point, Infrared Absorption (as published in FCC), Solubility, Taste/Odor, Color/Appearance, Heavy Metals and Predominant Active Chemical Components. Our in-house laboratory employs state-of-the-art analytical equipment that allows us to perform highly specialized analyses, such as Gas Chromatography and Infrared Spectrometry. We use our own analysis results to confirm specification sheet results and certificates of analyses received from 3rd party outside laboratories and vendors. As always, when it comes to Essential Oils, individual practitioners and lay people will decide for themselves which variety of a flower or leaf produces the essential oil that best suits their particular need. The nose, eyes, ears, hands and heart of a man or woman, used with humility and wisdom, are still the best tools given us by God to discern what is necessary and good. NOW Foods is committed to offering the purest and most potent natural Essential Oils available. All of our 100% Pure Essential Oils are FCC or food grade and derived through natural distillation or cold pressing methods with no chemicals or solvents. NR 9/03 My family and I have been using Cassia essential oil topically on our feet. Is this OK since your bottle says “Not for Topical use”? Skin irritation is possible with many oils, including the powerful Quassia or Cinnamon essential oils. Though many people do use our oils in a variety of ways, due to the powerful nature of steam distilled pure essential oils, we label these products with cautions and suggest that you consult an aromatherapist or health professional for proper use.

Date:
July 13, 2005 09:24 AM
Relaxation, Music Reduce Post-Op Pain. New research has found that relaxation and music, separately or together, significantly reduce patients' pain following major abdominal surgery. The study, published in the May issue of the journal Pain, found that these methods reduce pain more than pain medication alone. Led by Marion Good, PhD, RN, of Frances Payne Bolton School of Nursing, Case Western Reserve University, Cleveland, Ohio, the study is supported by the National Institute of Nursing Research (NINR), at the National Institutes of Health. "This is important news for the millions of Americans who undergo surgery and experience postoperative pain each year," said Dr. Patricia A. Grady, director of the NINR. "Better pain management can reduce hospital stays and speed recovery, ultimately improving patients' quality of life." Dr. Good and her research team studied three groups of patients undergoing abdominal surgery. In addition to the usual pain medication, one group used a jaw relaxation technique, another group listened to music, and a third group received a combination of relaxation and music. Findings revealed that, after surgery, the three treatment groups had significantly less pain than the control group, which received only pain medication. "Both medication and self-care methods which involve patient participation are needed for relief," said Dr. Good. "These relaxation and music self-care methods provide more complete relief without the undesired side effects of some pain medications." The findings have important implications for the 23 million people who undergo surgery and experience postoperative pain annually in the United States. Pain can hamper recovery by heightening the body's response to the stress of surgery and increasing tissue breakdown, coagulation and fluid retention. Pain also interferes with appetite and sleep and can lead to complications that prolong hospitalization. Dr. Good and her research staff worked with 500 patients aged 18-70, who were undergoing gynecological, gastrointestinal, exploratory or urinary surgery. Prior to surgery, those in the music, relaxation or combination groups practiced the techniques. The relaxation technique consisted of letting the lower jaw drop slightly, softening the lips, resting the tongue in the bottom of the mouth, and breathing slowly and rhythmically with a three-rhythm pattern of inhale, exhale and rest. Patients in the music group chose one of five kinds of soothing music--harp, piano, synthesizer, orchestral or slow jazz. On the first and second days after surgery, all patients received morphine or Demerol for pain relief by pressing a button connected to their intravenous patient controlled analgesia pumps. The groups receiving the additional intervention used earphones to listen to music and relaxation tapes during walking and rest, while the control group did not. The research team measured the patients' pain before and after 15 minutes of bed rest and four times during walking to see if the sensation and distress of pain changed. Dr. Good found that during these two days postsurgery the three treatment groups had significantly less pain than the control group during both walking and rest. "Patients can take more control of their postoperative pain using these self-care methods," says Dr. Good. "Nurses and physicians preparing patients for surgery and caring for them afterwards should encourage patients to use relaxation and music to enhance the effectiveness of pain medication and hasten recovery." Dr. Good's findings have implications for future research into the effectiveness of self-care methods on other types of pain, including chronic pain, cancer pain, and pain of the critically ill. ----------------------------- Vitamin D Lack Linked to Hip Fracture. Vitamin D deficiency in post-menopausal women is associated with increased risk of hip fracture, according to investigators at Brigham and Women's Hospital in Boston, Mass. In a group of women with osteoporosis hospitalized for hip fracture, 50 percent were found to have a previously undetected vitamin D deficiency. In the control group, women who had not suffered a hip fracture but who were hospitalized for an elective hip replacement, only a very small percentage had vitamin D deficiency, although one-fourth of those women also had osteoporosis. These findings were reported in the April 28, 1999, issue of the Journal of the American Medical Association. The study, conducted by Meryl S. LeBoff, MD; Lynn Kohlmeier, MD; Shelley Hurwitz, PhD; Jennifer Franklin, BA; John Wright, MD; and Julie Glowacki, PhD; of the Endocrine Hypertension Division, Department of Internal Medicine, and Department of Orthopedic Surgery, Brigham and Women's Hospital, Boston, was supported by grants from the National Institute on Aging (NIA) and the National Center for Research Resources (NCRR. These investigators studied women admitted to either Brigham and Women's Hospital or the New England Baptist Hospital, both in Boston, between January 1995 and June 1998. A group of 98 postmenopausal women who normally reside in their own homes were chosen for the study. Women with bone deterioration from other causes were excluded from the study. There were 30 women with hip fractures caused by osteoporosis and 68 hospitalized for elective joint replacement. Of these 68, 17 women also had osteoporosis as determined by the World Health Organization bone density criteria. All the participants answered questions regarding their lifestyle, reproductive history, calcium in their diet, and physical activity. Bone mineral density of the spine, hip, and total body were measured by dual X-ray absorptiometry (DXA) technique, as was body composition. Blood chemistry and urinary calcium levels were analyzed. The two groups of women with osteoporosis did not differ significantly in either time since menopause or bone density in the spine or hip. They did, however, differ in total bone density. The women admitted for a hip fracture had fewer hours of exercise than the control group. Fifty percent of the women with hip fractures were deficient in vitamin D, 36.7 percent had elevated parathyroid hormone (PTH) levels (a hormone which can stimulate loss of calcium from bone), and 81.8 percent had calcium in their urine, suggesting inappropriate calcium loss. Blood levels of calcium were lower in the women with hip fractures than in either elective group. These researchers propose that vitamin D supplementation at the time of fracture may speed up recovery and reduce risk of fracture in the future. Current Dietary Reference Intake Guidelines contain a daily recommendation of 400 IU of vitamin D for people aged 51 through 70 and 600 IU for those over age 70. "We know that a calcium-rich diet and regular weight-bearing exercise can help prevent osteoporosis. This new research suggests that an adequate intake of vitamin D, which the body uses to help absorb calcium, may help women to reduce their risk of hip fracture, even when osteoporosis is present," observed Dr. Evan C. Hadley, NIA Associate Director for geriatrics research. "Osteoporosis leads to more than 300,000 hip fractures each year, causing pain, frequent disability, and costly hospitalizations or long-term care. "Prevention of such fractures would greatly improve the quality of life for many older women and men, as well as significantly reduce medical costs." The bones in the body often undergo rebuilding. Some cells, osteoclasts, dissolve older parts of the bones. Then, bone-building cells known as osteoblasts create new bone using calcium and phosphorus. As people age, if osteoporosis develops, more bone is dissolved than is rebuilt, and the bones weaken and become prone to fracture. Also in many older persons, levels of vitamin D in the blood are low because they eat less or spend less time in the sun, which stimulates the body's own production of vitamin D. Experts do not understand fully the causes of osteoporosis. However, they do know that lack of estrogen which accompanies menopause, diets low in calcium, and lack of exercise contribute to the problem. Eighty percent of older Americans who face the possibility of pain and debilitation from an osteoporosis-related fracture are women. One out of every two women and one in eight men over the age of 50 will have such a fracture sometime in the future. These fractures usually occur in the hip, wrist, and spine. ----------------------------- Sleep Apnea, Diabetes Link Found. Adults who suffer from obstructive sleep apnea are three times more likely to also have diabetes and more likely to suffer a stroke in the future, according to a new UCLA School of Dentistry/Department of Veterans Affairs study published today in the Journal of Oral and Maxillofacial Surgery. Sleep apnea, a serious condition marked by loud snoring, irregular breathing and interrupted oxygen intake, affects an estimated nine million Americans. The culprit? Carrying too many extra pounds. "The blame falls squarely on excess weight gain," said Dr. Arthur H. Friedlander, associate professor of oral and maxillofacial surgery at the UCLA School of Dentistry and associate chief of staff at the Veterans Affairs Medical Center in Los Angeles. Surplus weight interferes with insulin's ability to propel sugars from digested food across the cell membrane, robbing the cells of needed carbohydrates. Diabetes results when glucose builds up in the bloodstream and can't be utilized by the body. Being overweight can also lead to obstructive sleep apnea, according to Friedlander. "When people gain too much weight, fatty deposits build up along the throat and line the breathing passages," he explained. "The muscles in this region slacken during sleep, forcing the airway to narrow and often close altogether." Reclining on one's back magnifies the situation. "When an overweight person lies down and goes to sleep," Friedlander said, "gravity shoves the fat in the neck backwards. This blocks the airway and can bring breathing to a halt." Friedlander tested the blood sugar of 54 randomly selected male veterans whom doctors had previously diagnosed with obstructive sleep apnea. He discovered that 17 of the 54 patients, or 31 percent, unknowingly suffered from adult-onset diabetes. Using the same sample, Friedlander also took panoramic X-rays of the men's necks and jaws. The X-rays indicated that 12 of the 54 patients, or 22 percent, revealed calcified plaques in the carotid artery leading to the brain. These plaques block blood flow, significantly increasing patients' risk for stroke. Seven of the 12, or 58 percent, were also diagnosed with diabetes. In dramatic comparison, the 17 patients diagnosed with diabetes showed nearly twice the incidence of blockage. Seven of the 17 men, or 41 percent, had carotid plaques. Only five of the 54 patients who displayed plaques did not have also diabetes. If he conducted this study today, Friedlander notes, he would likely find a higher number of diabetic patients. After he completed the study in 1997, the American Diabetes Association lowered its definition for diabetes from 140 to 126 milligrams of sugar per deciliter of blood. "This is the first time that science has uncovered a link between sleep apnea and diabetes," said Friedlander. "The data suggest that someone afflicted with both diabetes and sleep apnea is more likely to suffer a stroke in the future." "Persons going to the doctor for a sleep-apnea exam should request that their blood be screened for diabetes, especially if they are overweight," he cautioned. More than half of the individuals who develop diabetes as adults will need to modify their diet and take daily insulin in order to control the disease, he added. ------------------------------ Stress, Surgery May Increase CA Tumors. Stress and surgery may increase the growth of cancerous tumors by suppressing natural killer cell activity, says a Johns Hopkins researcher. Malignancies and viral infections are in part controlled by the immune system's natural killer (NK) cells, a sub-population of white blood cells that seek out and kill certain tumor and virally infected cells. In a study using animal models, natural killer cell activity was suppressed by physical stress or surgery, resulting in a significant increase in tumor development. These findings suggest that protective measures should be considered to prevent metastasis for patients undergoing surgery to remove a cancerous tumor, according to Gayle Page, D.N.Sc., R.N., associate professor and Independence Foundation chair at the Johns Hopkins School of Nursing. "Human studies have already found a connection between the level of NK activity and susceptibility to several different types of cancer," says Page, an author of the study. "We sought to determine the importance of stress-induced suppression of NK activity and thus learn the effects of stress and surgery on tumor development. "Many patients undergo surgery to remove cancerous tumors that have the potential to spread. If our findings in rats can be generalized to such clinical settings, then these circumstances could increase tumor growth during or shortly after surgery." The research was conducted at Ohio State University College of Nursing and the Department of Psychology at UCLA, where Page held previous positions, and at Tel Aviv University. Results of the study are published in the March issue of the International Journal of Cancer. In laboratory studies, Page and her colleagues subjected rats to either abdominal surgery or physical stress, and then inoculated them with cancer cells. In the rats that had undergone surgery, the researchers observed a 200 to 500 percent increase in the incidence of lung tumor cells, an early indicator of metastasis, compared with rats that had not received surgery. The experiment also showed that stress increased lung tumor incidence and significantly increased the mortality in the animals inoculated with cancer cells. "Our results show that, under specific circumstances, resistance to tumor development is compromised by physical stress and surgical intervention," says Page. "Because surgical procedures are life-saving and cannot be withheld, protective measures should be considered that will prevent suppression of the natural killer cell activity and additional tumor development. "Researchers do not yet know how to prevent surgery-induced immune suppression, but early animal studies have shown increased use of analgesia reduces the risk." The study was funded by the National Institutes of Health, and the Chief Scientist of the Israeli Ministry of Health. Lead author was Shamgar Ben-Eliyahu, Ph.D., and other authors were Raz Yirmiya, Ph.D., and Guy Shakhar.

Cross Training by column Energy Times, April 1, 1999 If you've ever felt burned out, bored and/or just plain tired of your exercise program, you may be in need of a taste of cross training. When your exercise routine becomes too routine, you run not only the risk of losing your motivation for physical activity, but you may also run an added chance of injury. The possible cause: overusing particular muscles that receive an excessive amount of stress as other muscles practically atrophy while waiting for a chance to show off their stuff. For instance, if you are a devoted runner who spends hours jogging, your upper body may wither unless you give it a reason not to. At the same time, your achilles, hamstrings, knees and lower back muscles may protest those miles after miles. As Frank Jobe, MD, Neal EllAttrache, MD, and Karen Mohr, PT, point out in Athletic Forever (Contemporary), "Dedicated runners are among the most injury-prone of all athletes. If running is your main form of exercise, you have a 37 to 56 percent chance of sustaining an injury each year and your chances for a recurrence of that injury are as high as 70 percent." Simple Principle The basic principle of cross training is simple: take part in various activities that supplement each other. Runners should lift some weights or at least shoot a few hoops to keep those arms and shoulders toned. Bikers should walk or run now and then to keep their bones healthy. (Bicycling, since it is not a weight bearing exercise, does little to promote bone strength.) Swimmers should find something to do on dry land so that their bones react to gravity and grow stronger. And, no matter what your sport, you should stay well-nourished and supplied with plenty of antioxidants. As Stephen T. Sinatra, MD, points out in Optimum Health (Bantam), while athletes may enjoy health benefits from exercise, "The vigorous training pursued by competitive athletes renders them more prone to catabolic stress-a situation in which tissues are constantly broken down." He goes on to point out that the low fat diet many athletes follow may be short of antioxidant nutrients. Unfortunately, that shortage can lead to injury. The metabolic acceleration caused by athletic activity may increase potentially harmful oxidative stress at the cellular level. Without antioxidant nutrients to help quell that stress... Well, the results may not be pretty. Potentially, that kind of oxidative damage may, theoretically, lead to cancer or heart disease. As Dr. Sinatra says, in those circumstances, "the supplemental use of glutathione, vitamins C and E, coenzyme Q10 and magnesium seems reasonable. Some athletes, such as menstruating women, may also need iron supplementation." In addition, water is crucial for athletes to stay adequately hydrated during activity. According to Daniel Gastelu and Fred Hatfield, PhD, in Dynamic Nutrition for Maximum Performance (Avery), when you run short of water "this can adversely affect performance and, in the long run, can cause peaks and valleys in the athlete's performance." In addition, they advise using sports drinks to stay adequately supplied with electrolytes. "The major electrolytes found in bodily fluids are chloride, magnesium, potassium and sodium." Electrolytes serve a host of duties, including keeping the heart muscle functioning properly. Gastelu and Hatfield explain, "An electrolyte is an ion that is required by the body to regulate the electric charge and flow of water between the cells and the bloodstream." Getting Better All the Time Even if you cross train religiously and try to avoid overdoing one particular sport, sooner or later you may incur injury. If you do (or even before you hurt yourself), the trio of Stanley W. Jacob, MD, Ronald M. Lawrence, MD, PhD, and Martin Zucker, authors of The Miracle of MSM (Putnam), believe that methylsulfonylmethane (MSM) can provide reliable relief for pain and suffering. "Many people experience rapid relief after starting MSM," say this trio. They go on to claim that "this nutritional supplement has real potential to make a significant impact on the quality of life." "Your main enemy in the hours following an injury is inflammation," warns Athletic Forever. For injury, they recommend RICE: rest, ice, compression and elevation. In other words, put the injured body part in a firmly wrapped bandage (don't cut off the circulation!) Keep the injury cold but don't put ice directly on it (watch out for frost bite). Rest a while and keep the injury elevated. Then, don't exercise again until you've fully recovered.
