There are about hundreds of castor oil factories in China, of which only about 10% castor oil manufacturers start working; large processing plants have around 20; only nine plants have tens of thousands processing capacity. About 70% of Chinese castor oil processing factories in stop production or semi-shutdown state, because there are no adequate, high-quality raw material castor sources. At the end of the 1980s, China extends and built several large scale castor oil factories, each factory's total amount of annual output of castor oil are in 10 -15 thousand tons, total production capacity is about 55,000 tons per year. The world's major markets of castor oil were concentrated in North America and Europe, of which the France, Britain, Netherlands, United States, Germany, five countries accounted for 61% of annual fuel consumption. India castor oil used in making soap has about 1.6-1.8 million tons, the textile industry uses 2-3 thousand tons, chemical industries use 2-3 thousand tons, lubricating oil use 5-6 thousand tons, the rest for exporting. In Japan's castor oil use amount, paints accounted for 28.6%, the surfactant is 12.3%, cosmetic raw material is 8.2%, resin is 5.7%, hardened oil is 17.8%, sebum oil is 12.9%, others is 14.5%. Japan needs to import large quantities of castor beans every year; they are mostly imported from China, Pakistan, Indonesia, Sri Lanka, Philippines, Vietnam, Ethiopia, Brazil and other countries. Castor oil in the United States for the production of plastics and resins was accounted for 25.9%, fatty acids accounted for 12.7%, lubricating oil accounted for 6.3%, paint accounted for 23.7%, cosmetics (mainly synthetic waxes) accounted for 2.1%, others such as inks, surfactants accounted for 29.1%, these castor oils are imported from foreign countries. Every year, the world needs 700 thousand tons of castor oil, convert into 1.6 million tons castor beans. Nowadays, gasoline resource was gradually reduced, transportation, live used gasoline was rapidly increasing, use gasoline as a raw material for synthetic material will be increasingly constrained in cost. And the United States study found that long-term exposure to polymers which synthesized by gasoline was harmful to human health. California and some other states have enacted laws and regulations for this, to restrict and gradually prohibit using synthetic resin in city buildings, interior facilities and human health-related sites and articles, which is polymerized from petroleum, natural gas cleaved into monomers raw materials, it makes castor oil's demand was rising sharply. Castor cultivation in China is very commonly; there is no open planted regional division. South from Hainan Island, north to Heilongjiang is cultivated. Because castor hybrids with drought resistance, thin ridge resistant, Saline-alkaline tolerance, well-adapted, simple to manage, less invest, high efficiency and other salient features, no matter grain field or hills, rocky land, Saline-alkali soil and even around the house can be grown it. So anywhere in China can be planted castor. Related Products

Supports normal heart function*
A significant amount of in vitro, animal and human research suggests benefits of ribose on heart function.* Studies have shown that ribose supplementation can enhance cardiac energy levels and support cardiovascular metabolism.* Ribose has been shown in clinical trials to enhance the recovery of heart muscle ATP levels and improve myocardial function following exercise.
Studies suggest that ribose supplementation can increase the tolerability of the cardiovascular system to exercise-induced fatigue.1 In one study, twenty men underwent treadmill exercise tests on two consecutive days to confirm the onset of fatigue secondary to exercise. The participants were then randomized to the treatment group or a placebo group. The groups received either four doses of 15 grams of D-ribose (60 grams/day total) or the same amount of placebo each day. After three days of treatment, another treadmill test was performed. The time it took to reach the specified level of fatigue was significantly greater in the ribose group than in the placebo group.
Another study investigated the ability of ribose to support healthy heart function and quality of life.2 In a randomized, crossover design study, fifteen individuals were given 5 grams three times a day of either D-ribose or placebo. Each treatment period lasted three weeks. In patients receiving ribose, echocardiography demonstrated enhancement of heart function, reflecting a “more efficient relaxation phase of the heart”. Participants also had a significant improvement in their subjective quality of life scores compared to placebo.
Scientists suggest that suboptimal heart function is a result of the heart requiring more energy to function properly. Ribose supports the heart’s enhanced energy requirements, promoting optimal heart function. It does so by enhancing the stores of high-energy phosphates in heart tissue. These intermediates are necessary for the production and resynthesis of ATP. A double-blind crossover study in which 12 individuals were randomized to receive either ribose or dextrose (both administered as 5 grams three times daily for three weeks, followed by a 1-week washout period and crossover of treatments for three additional weeks) suggested significant enhancements in normal cardiac function during the period of ribose supplementation.3
Perhaps one of the more useful illustrations of the potential for ribose to support heart function comes from a study in which 20 rats received a continuous infusion of ribose for 24 hours (control rats received an infusion of Saline). The hearts were then explanted (as they would be for heart transplants) and placed in preservation solution that was enriched with ribose for 4 hours. ATP levels were measured from tissue biopsies and revealed that 10 of the ribose-treated hearts had ATP levels higher than 12.3 micromoles per gram whereas Saline-treated hearts (controls) had lower ATP levels, with 20% showing levels below 10 micromoles per gram of tissue. This provides support for the hypothesis that ribose may enhance the preservation of ATP levels in cardiac tissue, promoting normal heart function.4
Further animal studies have shown that ribose significantly enhances heart function after experimentally induced cardiac depression. Rats were injected with isoproterenol (a drug that stimulates sympathetic nervous system function) and had their abdominal aorta constricted to induce depression of heart function and reduce cardiac ATP levels. The decrease in ATP was primarily responsible for the depression of heart function. Continuous infusion of ribose for 24 hours replenished ATP concentrations to normal levels and normalized heart function in these animals.5
Ribose may strengthen and support the body’s crucial antioxidant defenses*
Ribose may support the body’s innate antioxidant mechanisms while promoting an antioxidant effect of its own. Intense exercise and other strenuous activity can induce the production of free radicals. Preliminary studies suggest that ribose can attenuate some of the effects of oxidation seen after performance of intensive exercise.
One small human study indicated that ribose administered at a dose of seven grams before and after a bout of cycling exercise may reduce free radical production.6 Seven volunteers ingested either ribose or placebo both before and after intense exercise. Markers of lipid peroxidation, including malondialdehyde, significantly decreased in the ribose-supplemented group, while increasing in the control group. The results of this study indicate a possible effect of ribose in supporting antioxidant activity.
Supports healthy energy levels in heart and muscle tissue*
After bouts of intense exercise, ATP levels have been shown to decrease by an average of 15 to 20%.7 The amount of ATP stored in the muscle is limited and so the body must have the potential to rebuild ATP stores. ATP is the fuel necessary for the integrity and function of a cell. In addition, several studies have found correlations between ATP content and heart function.1 Research that was also alluded to above suggests that ribose stimulates ATP synthesis and supports heart and muscle function by enhancing ATP levels in cardiac and muscle tissue. D-ribose is an essential building block for the synthesis of ATP through the pentose phosphate pathway.
The results of ribose supplementation enhancing ATP levels in muscle are evidenced by studies suggesting beneficial effects on anaerobic performance. In a randomized, placebo-controlled crossover study assessing the effects of acute ribose supplementation, participants receiving the ribose supplement had increases in mean power (a measure of average overall muscular strength output during the sprint) and peak power (a measure of the highest muscular strength output during the sprint) when undergoing a series of cycle sprints.8 While this effect was not noted in all of the six short cycling sprints that the participants underwent, the study does illustrate the potential benefits of ribose on ATP production and, secondarily, on enhancing exercise performance.
A second placebo-controlled trial investigated the effects of four weeks of ribose-supplementation (10 grams /day) on male bodybuilders. Of the 20 participants who were recruited, twelve completed the study. Each subject participated in a heavy-resistance training program designed to increase skeletal muscle mass. The effects of ribose on body composition (body weight, body fat, lean body mass, fat mass, and bone mineral content) were also assessed. The results suggested that ribose increased total work capacity and bench press strength compared to placebo, without altering body composition.9
Supports energy recovery after exercise*
Animal studies have suggested that the administration of ribose after exercise increases the rate of adenine salvage by five to seven-fold in muscle tissue7, supporting energy recovery after exercise. When ATP is utilized by muscle tissue, the degradation products include adenine nucleotides (Adenine is one of two purine bases that is a component of DNA). Adenine is recycled to synthesize DNA, and the salvage of adenine within the muscle tissue is crucial to energy recovery. Studies have shown that the presence of adequate ribose concentrations is the rate-limiting step in the purine salvage pathway. Therefore, increased adenine salvage could potentially help in the recovery and regeneration of ATP after intense bouts of activity.
A study investigated the effect of oral intake of ribose on the synthesis of AMP, a precursor to ATP.10 Participants performed intense cycle training for seven days. They then received either ribose (at a concentration of 200 mg/kg body weight, which is equivalent to 14 grams per day for an average 70 kilogram male) or placebo three times a day for the following three days. Exercise tests were performed again on day 4. Muscle biopsy samples were taken before the first training session, immediately after, and again five hours, 24 hours, and 72 hours after the last training session. No differences were seen in exercise performance between the groups. The intense exercise caused the ATP levels in muscle to decrease in both groups. However, at 72 hours post-exercise, the ribose group exhibited a much higher ATP level than the placebo group. The muscle levels of critical building blocks for ATP, including total adenine nucleotides (TAN) and inosine 5’-monophosphate (IMP), were also significantly higher in the ribose group compared to the placebo group at 24 hours after exercise. Ribose-supplementation was shown to enhance the resynthesis of ATP after intense exercise.

Silibinin, a flavonone compound found in milk thistle, helped hinder the progess of lung cancer in an animal study, according to findings published in the journal of the national cancer institute (2006, vol.98: 846-885). Researchers divided 90 mice into six groups and injected 75 of them with cancer causing urethane and in the remaining 15, a Saline solution as a control. After two weeks the normal diet, the five groups injected with urethane were fed a diet supplemented with various doses of silibinin (zero, 0.033, 0.10, 0.33, and 1.0 percent). After 18 and then 29 weeks, the silibinin groups showed between 32 and 38 percent fewer tumors and 64 to 70 percent fewer tumors, respectively, than the control group. The group with the highest dosage of 1.0 percent silibinin had 93 percent fewer large tumors than the urethane-only group. Regarding spread of cancer, the silibinin fed mice had between 41 and 74 percent fewer cancer cells that tested for spread markers.

Benefits • Supports Healthy Joint Structure and Function* Components of BioCell Collagen II including collagen type II, chondroitin sulfate and hyaluronic acid (HA) can enhance proteoglycans in the joint matrix, thereby providing support for healthy joint function and maintaining joint shock absorption and cushioning. CHONDROITIN SULFATE Chondroitin has been well studied for its effects on joint health. In a 1996 controlled, double-blind trial published in the Journal of Rheumatology, 146 volunteers consumed chondroitin sulfate daily for 6 months. Changes in joint function were measured according to several clinical parameters and carefully analyzed. After the first month, significant improvements were noted and maintained for three months after the subjects stopped taking the chondroitin sulfate.1 In an earlier double-blind study subjects taking chondroitin sulfate had improvements in joint function after three months of use, as determined by both objective and subjective measurements.2 In both studies, the benefits lasted for weeks after subjects stopped taking chondroitin sulfate. In another controlled study, 192 subjects took chondroitin sulfate or a placebo daily for one year. At the end of the trial, chondroitin sulfate maintained healthy joint cartilage thickness, while those on placebo had decreased cartilage. Improvements in joint function also occurred. The researchers reported that chondroitin exerted a clear chondroprotective effect.3 COLLAGEN TYPE II A number of studies have also been conducted on the administration of collagen type II to individuals that have various joint issues. Much of this research has been conducted on animal models of joint conditions while there are also studies showing the effectiveness of oral collagen type II preparations in humans for maintenance of healthy joints. A randomized controlled trial conducted on 60 patients with joint health issues in 1993 found that oral administration of chicken collagen type II for 3 months led to a significant decrease in swollen and tender joints in this group, as compared to no measurable improvement in the placebo group. There were also no side effects seen with the treatment.4 A second multicenter, double-blind, placebo-controlled trial in 274 individuals with joint issues was published in 1998. The participants were given collagen type II orally for 24 weeks. Positive effects of the treatment were noted while no adverse effects were seen.5 A paper published in 2000 reviewed the literature to assess the role of hydrolyzed collagen in joint and bone health. It was found that hydrolyzed collagen when administered orally was able to support joint health in most of the trials reviewed while the author concluded that, “Its high level of safety makes it attractive as an agent for long-term use.”6 HYALURONIC ACID (HA) Most of the literature on hyaluronic acid and joint health deals with its intra-articular use, or injections of HA directly into the joints. In this realm, there is good evidence for the effects of HA on joint function. A study was conducted with injectable HA in individuals with TMJ (temporomandibular joint) conditions. Participants received two injections, each one week apart, or placebo injections with Saline. In the HA group, the researchers found decreased clicking sounds and increased function of the joint at 1 month (90% of patients showed improvement) and 6 months (63%) of follow-up, compared to about 26% of the placebo group showing improvement at 6 months.7
A pair of researchers also conducted a literature review of the trials using HA for improving joint health that was published in 2005. Their findings indicate a positive role for HA in modifying the structure of the joint and slowing progressive deterioration of joint function and mobility.8 Hyaluronic acid seems to have a natural affinity for joint tissue, and is therefore able to help support healthy joint structure and function.
• SuSupports Healthy Joint Structure and Function* Hyaluronic Acid and Collagen are both vital components of skin tissue. Both compounds are known to decline with aging. Collagen is a vital structural component of the skin. It is also one of the most important substances required for proper skin barrier function and health. Collagen, as a major component of the connective tissue, provides structural support, increasing elasticity and tone of the skin. In 1994, researchers performed comparative measurements of hyaluronic acid levels in the skin of young and elderly individuals. The researchers had hypothesized that a major reason for the aged appearance of skin in the elderly is a reduction of hyaluronic acid levels. What they found using their methods is that there is a progressive reduction in the number of hyaluronic acid granules in human skin with age, until a complete absence of these granules was seen in individuals 60 years or older. These variations in HA levels with age could, according to the researchers, account for the decreased turgidity, wrinkled appearance and altered elasticity of skin tissue.9 Further research was needed to determine the effect of exogenously administered HA on the suppleness of human skin. In a laboratory study conducted in 1998, researchers analyzed the effects of HA given to live human skin cells. Whereas the cells on their own had a low rate of renewal, hyaluronic acid added to the cells resulted in increased proliferation of skin cells in the collagen matrix. This showed that supplementing skin cells with HA caused a significant increase in the ability of cells to go through the cell cycle.10 One of the major benefits of this may be hyaluronic acid’s ability to continually renew skin tissue to help maintain a youthful appearance of the skin.

Date:
June 14, 2005 05:23 PM
America's Most Wanted by Brian Amherst Energy Times, January 6, 2000 The United States eats well, a little too well, according to experts. Amply supplied with a large supply of high-calorie food, our diets might seem to be chock full of every conceivable nutrient. Well, to the question "Getting all the right vitamins, minerals and other nutrients?" the most appropriate answer seems to be "Not exactly." Eating a lot doesn't equal eating a lot of the most important vitamins and minerals. So, which vitamins and minerals are likely to show up in short supply in the typical American diet? Calcium certainly sits at the top of list. According to the most recent Continuing Survey of Food Intake by Individuals, which is conducted by the United States Department of Agriculture (USDA), women and girls age 12 and up are not consuming adequate calcium from their diet. Research reveals that about 1200 mg. day suffices for those over age 50 and 1000 mg a day should be adequate if you're between the ages of 19 and 50. Since strong bones are formed during "the first three decades of life," says Laura Bachrach, MD, of Since strong bones are formed during "the first three decades of life," says Laura Bachrach, MD, of Stanford University, ". . .osteoporosis is a pediatric disease." For long-range protection against that bone-weakening disease, kids should eat calcium-rich, low-fat dairy products and plenty of leafy greens (broccoli, cabbage, kale) as well as salmon (with bones), seafood and soy. But the calcium campaign does not end in early adulthood. Bone mass begins to deteriorate at about age 30. Menopausal hormonal changes can exacerbate bone brittleness. Medical conditions, including cancer, liver disease and intestinal disorders; prescription drugs; tobacco and alcohol indulgence; or a decline in activity, especially the weight-bearing kind, also jeopardize bone strength. According to the National Osteoporosis Foundation, about one in every two American women will break a bone after age 50 due to osteoporosis. That translates into about half a million fractured vertebrae and more than 300,000 shattered hips. Frequently, those breaks are life-threatening. Crucial Calcium The critical role of calcium in many body functions is perhaps the most extensively clinically documented among nutrients. Researchers in the Department of Medicine, Oregon Health Sciences University in Portland, reviewed epidemiological and clinical studies conducted over the past two years on the relationship between dietary calcium and blood pressure (J Am Coll Nutr October 1999: 398S-405S). "Nearly 20 years of investigation in this area has culminated in remarkable and compelling agreement in the data," the researchers report, "confirming the need for and benefit of regular consumption of the recommended daily levels of dietary calcium." Investigators at the State University of New York, Buffalo School of Dental Medicine, presented results of their studies of calcium and vitamin C and gum disease at the June 26, 1998 meeting of the International Association for Dental Research. Two separate inquiries revealed that people who consumed too little calcium as young adults, and those with low levels of vitamin C in their diets, appear to have nearly twice the risk of developing periodontal disease later in life than folks with higher dietary levels of either nutrient. Calcium: Much Documented Researchers offer extensive evidence of calcium's benefits on many fronts: n Osteoporosis poses a threat to older men as well as women, according to Randi L. Wolf, PhD, research associate at the University of Pittsburgh Graduate School of Public Health. Dr. Wolf presented her award-winning study to an October 3, 1999 meeting of the American Society for Bone and Mineral Research. Dr. Wolf suggests that men increase their consumption of calcium, particularly after age 80, to avoid age-related declines in the amount of calcium absorbed. According to Dr. Wolf, "It appears that the hormonal form of vitamin D, which is the main regulator of intestinal calcium absorption, may have an important role. We are conducting more research to better understand the reasons for why calcium absorption declines with age in men." n Scientists at Tufts University in Boston did some earlier work on the calcium-vitamin D connection and reported it in the September 4, 1997 New England Journal of Medicine. Using the National Academy of Sciences (NAS) increased recommended daily intake of 1200 milligrams of calcium and 400 to 600 international units of vitamin D for people over 50, the Tufts researchers found that with supplementation of the nutrients, men and women 65 and older lost significantly less body bone and, in some cases, gained bone mineral density. n Two studies published in American Heart Association journals show that atherosclerosis and osteoporosis may be linked by a common problem in the way the body uses calcium. The September 1997 Stroke revealed that, in a group of 30 postmenopausal women 67 to 85 years old, bone mineral density declined as atherosclerotic plaque increased. Researchers reporting in Circulation (September 15, 1997) advanced the theory that the osteoporosis-atherosclerosis connection may be related to a problem in handling calcium. n For people who had colon polyps removed, taking calcium supplements decreased the number of new polyps by 24% and cut the risk of recurrence by 19%, according to researchers at the University of North Carolina, Chapel Hill, School of Medicine. The study, published in the January 14, 1999 New England Journal of Medicine, was a first in crediting calcium with anti-cancer properties. The D Factor Without adequate vitamin D, your absorption of calcium slips and bone loss can accelerate, increasing the risk for fractures. Fifty percent of women with osteoporosis hospitalized for hip fractures at Brigham and Women's Hospital in Boston had a previously undetected vitamin D deficiency (Journal of the American Medical Association, April 28, 1999). University of Pittsburgh Cancer Institute researchers told participants at the April 14, 1997 meeting of the American Association for Cancer Research that vitamin D "significantly inhibits highly metastatic, or widespread, prostate cancer in animals," suggesting its potential for treating men with similar conditions. Few foods that Americans eat, except dairy, contain much vitamin D, but we can usually synthesize sufficient amounts from as few as five minutes' exposure to the sun. But as skin ages, its ability to act as a vitamin D factory decreases. According to Michael F. Holick, the director of the Vitamin D, Skin and Bone Research Laboratory at Boston University Medical Center, upwards of 40% of the adult population over age 50 that he sees in his clinic are deficient in vitamin D. Recently, the National Academy of Sciences (the official body that decrees the required amounts of necessary nutrients) increased the daily recommendations of vitamin D to 600 IU for people over 71, 400 IU for those aged 51 to 70 and 200 IU for people under 50. The best dietary sources, apart from dependable supplements, are dairy and fatty fish like salmon. Four ounces of salmon provide about 300 IU. The Facts About Fats The American lust for low-fat, high-carbohydrate diets filled with sugary foods has exploded into nothing short of "obsession," according to experts at the General Research Center at Stanford University Medical Center (Am J Clin Nutr 70, 1999: 512S-5S). That mania oftens robs us of the crucial balance of omega-3 and omega-6 fatty acids typical of the Mediterranean diet that protect us from heart disease by controlling cholesterol and making blood less likely to form clots. These fatty acids cannot be made by the body but are critical for health: n Omega-3 fatty acid (linolenic acid) comes from fresh, deepwater fish (salmon, mackerel, sardines) and vegetable oils such as canola, flaxseed and walnut. n Omega-6 fatty acid (linoleic acid) found primarily in raw nuts, seeds and legumes and in saturated vegetable oils such as borage, grape seed, primrose, sesame and soybean. The American Heart Association recommends limiting total fat consumption to 30% of daily calories. Saturated fats like those in dairy and meat products as well as vegetable oil should comprise 10% of total calories; total unsaturated fat (fish oils, soybean, safflower nuts and nut oils) should be restricted to 20 to 22% of daily calories. Be Sure About B12 Vitamin B12 presents a particular problem for the elderly because older digestive systems often don't secrete enough stomach acid to liberate this nutrient from food. (The elderly have no problem absorbing B12 from supplements, because it's not bound to food.) Vitamins generally moderate the aging process but, ironically, that process and the diseases that frequently accompany it affect vitamin metabolism (Schweiz Rundsch Med Prax 83, 1994: 262-6). And because of those changes, we need more of certain vitamins. This is the case for vitamins D, B6, riboflavin and B12. Crucial for health, B12 is necessary to prevent anemia, and, according to recent studies, needed (along with folate and B6) to help stave off heart disease. B12, with thiamine and niacin, boosts cognition (Adv Nutr Res 7, 1985: 71-100). Screening for vitamin B12 deficiency and thyroid disease is cheap and easy and can prevent conditions such as dementia, depression or irreversible tissue damage (Lakartidningen 94, 1997: 4329-32). In the January 5-12, 1999 issue of Circulation: Journal of the American Heart Association, the AHA urged doctors to screen levels of homocysteine (the amino acid byproduct of protein digestion that damages arteries, causes heart disease and, possibly, strokes) in patients at high risk for heart disease. They also recommended all Americans to up their daily levels of vitamins B6 and B12, as well as folic acid. Since fruits, vegetables or grains lack B12, vegetarians need B12 supplements. And they're a good idea for the rest of us, too. Folic Acid Benefits Folic acid made headlines in the early 1990s when the U.S. Public Health Service declared that "to reduce the frequency of neural tube defects [spina bifida, or open spine, and anencephaly, a lethal defect of the brain and skull] and their resulting disability, all women of childbearing age in the United States who are capable of becoming pregnant should consume .4 milligrams (400 micrograms) of folic acid per day." This recommendation followed voluminous research that showed taking folic acid was associated with a significantly reduced risk of birth defects. (The advisory is based on the fact that nearly half of all pregnancies are unplanned. If you think you are pregnant, consult your health practitioner for supplementary advice.) A Team Player Folic acid's efficacy intensifies when it works with other nutrients. Among many studies on the preventive powers of folic acid on birth defects, one published in The New England Journal of Medicine (327, Dec. 24, 1992: 1,832-1,835), disclosed an even greater decrease in neural tube defects when supplements of folic acid contained copper, manganese, zinc and vitamin C. As a warrior against homocysteine, folic acid joins the battalion of B12 and B6 in detoxifying this harmful protein. At the University of Washington's Northwest Prevention Effectiveness Center, researchers recently analyzed 38 published studies of the relationship between folic acid, homocysteine and cardiovascular disease and, according to associate professor Shirley A. Beresford, MD, folic acid and vitamin B12 and B6 deficiencies can lead to a buildup of homocysteine. Compelling Evidence Canadian researchers reported in the Journal of the American Medical Association (275, 1996: 1893-1896) that men and women with low folic acid have a 69% increase in the risk of fatal coronary heart disease. This 15-year study of more than 5,000 people stressed the need for dietary supplementation of folic acid. Folic acid also has been credited with the potential to protect against cancers of the lungs, colon and cervix. It appears to help reverse cervical dysplasia, the precursor cells to cervical cancer, especially for women taking oral contraceptives, which may cause a localized deficiency of folic acid in the cells of the cervix. According to Shari Lieberman, PhD, and Nancy Bruning, authors of The Real Vitamin & Mineral Book (Avery), folic acid derivatives work with neurotransmitters, the chemicals that permit signals to be sent from nerve fiber to nerve fiber. A lack of folic acid can cause some nervous-system disorders, such as depression, schizophrenia and dementia; it also may be related to some forms of mental retardation. Other supporting roles of folic acid, according to researchers: the formation of normal red blood cells, important for preventing the type of anemia characterized by oversized red blood cells; strengthening and improving white blood cell action against disease; limiting production of uric acid, the cause of gout. The Best Sources Many foods are rich in folic acid: beef, lamb, pork and chicken liver, spinach, kale and beet greens, asparagus, broccoli, whole wheat and brewer's yeast. But experts believe that only 25 to 50% of the folic acid in food is bioavailable. Processing also reduces an estimated 50 to 90% of its content. Folic acid supplementation overcomes these obstacles with little risk, as it has no known toxicity. Women taking folic acid who are current or former users of oral contraceptives may require additional zinc. And be sure to augment your folic acid supplement with its synergistic counterpart, vitamin B12. Focus on Fiber The American Heart Association came out squarely behind fiber in a June 16, 1997 issue of its journal Circulation: Double your daily intake to lower cholesterol and the risk of heart disease. The American diet is consistently low in fiber, notes Linda Van Horn, PhD, RD, author of the article. Twenty-five to 30 grams a day from foods (or supplements) are not only heart healthy but seem to aid weight control. Iron Problem Getting enough iron? An estimated 25% of adolescent girls in the United States are iron deficient, according to an October 12, 1996 issue of the British medical journal The Lancet, which reported that girls who took iron supplements performed significantly better on verbal tests than those who took a placebo. "Teenage girls should be regularly tested for iron deficiency because rapid growth and the onset of menstruation during puberty increase the body's need for iron," says Ann Bruner, MD, of the Johns Hopkins Children's Center and a lead author of the study.USDA data reveal that women up to age 50 also tend to get much less than recommended levels of iron, a lack of which leads to anemia, a deficiency of red blood cells, hemoglobin or volume of blood. For kids, deficiency is more common from six months to four years and during the rapid growth spurts of adolescence when the body is growing so quickly that the body's iron stores may sink to dangerous levels. Vegetarian women run the greatest risk for deficiency, as meat is iron-rich; foods like beans, grains and vegetables also contain some iron. Supplements, of course, supply easily absorbable iron. And to absorb iron from vegetarian sources, take vitamin C with your meals. That boosts the amount of this mineral you will take in. Bear in mind, however, that certain folks-older men and post-menopausal women-generally have adequate dietary supplies of iron. Of greater concern, in fact, is excessive iron, and for these folks iron-free multivitamin and mineral supplements are available. Ante Up the Antioxidants Antioxidant nutrients help protect the body from oxygen-scavenging molecules called free radicals. The products of pollution, the body's own metabolic processes and other sources, free radicals are linked to heart disease, cancer and other chronic health problems. The most important antioxidants, which include vitamin C, E, beta carotene, and selenium, are often lacking in the American diet. Plus, optimal amounts of vitamin E cannot be consumed from food. You need supplements. The bottom line: even though we live in a land of plenty, you can still miss vital nutrients. So make sure to consume these vital substances. Sprouts: Nutritional Source of Missing Nutrients In the search for the nutrients missing from America's diet, one big help is the sprout. The sprout is truly one of nature's heavyweights: fresh, tiny and moist, its power punch of vitamins, minerals, protein, chlorophyll and disease-busting phytochemicals land it in a weight class far beyond that of its full-grown competitors. Size does NOT matter to this nutritional giant. A championship belt currently wraps around the miniscule broccoli sprout, catapulted into the ring by Paul Talalay, MD, professor of pharmacology and molecular sciences at Johns Hopkins University. Dr. Talalay discovered that the seedlings contain substantially more of the cancer-fighting substance sulforaphane than mature plants (Proc. Natnl. Acad. Sci. USA, 94, 10367-10372). Sprouts, the quintessential health food of the Sixties, provide a wonderfully varied and versatile way to get your daily greens. Raw or cooked, strong or mild, vegetable and grass sprouts and their algae cousins add low-calorie texture to recipes and a rich, diverse complement of nutrients and fiber. Ancient Asia to the Modern Lab Asians stir-fried sprouts as one of the earliest fast foods as long as 5,000 years ago. The ancient Chinese relied on sprouts for year-round vegetables in colder regions of their vast country. Today, researchers studying sprouts and adult plants have identified their important chemoprotective and other health-bolstering substances. In Paul Talalay's research project at Johns Hopkins, scientists found that three-day-old broccoli sprouts contain up to 50 times more sulforaphane than mature plants, which prompts the body to produce an enzyme that prevents cancer tumors from forming. Uniform levels of the compound saturate the shoots, unlike the chemically uneven adult plants. The Brassica family of broccoli and cabbage is richly endowed with phytochemicals that also help reduce estrogen levels associated with breast cancer. Other phytochemical compounds in the Brassica family are associated with the prevention of stomach and lung cancers. Most of the initial landmark work on phytochemicals' cancer-fighting powers has taken place since 1989 under the aegis of the National Cancer Institute's "Designer Food Program," which isolated, for example, the isoflavones in beans that seem to neutralize cancer-gene enzymes. Strong Suit: Soy and Spirulina The isoflavones and phytosterols in soy produce an estrogenic effect that appears to relieve menopausal symptoms and help prevent breast cancer. Soy foods expert Mark Messina, PhD, has done extensive work on the subject, some of which has been published in the Journal of the National Cancer Institute 83, 1991: 541-6. Researchers also have synthesized a bone-strengthening form of soy isoflavones called ipriflavone, following impressive clinical trials in the treatment of osteoporosis (American Journal of Medicine, 95 [Suppl. 5A] (1993): 69S-74S). Spirulina and other micro-algae are fascinating organisms that inhabit a niche between the plant and animals kingdoms. Named for its tiny spirals, spirulina, a blue-green algae, grows in Saline lakes but is cultured for maximum nutritional content. In her book Whole Foods Companion (Chelsea Green), Dianne Onstad notes that spirulina contains "the highest sources of protein, beta carotene and nucleic acids of any animal or plant food." Its nucleic acids, she says, benefit cellular regeneration; its fatty acids, especially GLA and omega-3 acids, make it one of the most complete foods. Sprouts, like any other produce, should be rinsed thoroughly before serving. People at high risk for bacterial illness-young children, the very elderly or folks with weakened immune systems-should limit their consumption of raw sprouts. But no matter how you eat them, you may find more spring in your step from these tiny, sprouting nutritional wonders.

Abstract Objectie :To investigate the effect of vinpocetine on cerebral blood flow (CBF) in the compromised circulation of a stroke affected hemisphere using transcranial Doppler (TCD) and near infrared spectroscopy (NIRS) methods. Methods : 43 patients with ischemic stroke were randomized into vinpocetine (VP) and placebo group in a double blind, placebo-controlled study of the effect of a single-dose i.v. infusion of vinpocetine on cerebral blood perfusion and oxygenation. In the VP group 20 mg VP in 500 ml Saline, in the placebo group 500 ml Saline alone were administered. The concentrations of oxy-, reduced- and total hemoglobin were measured by NIRS frontolaterally on the side of lesion while the mean cerebral blood flow velocity (CBFV), the pulsatility index (PI) and Doppler spectral intensity (DSI) were monitored by TCD in the middle cerebral artery on the same side. Values were averaged for the first 5 min prior to the infusion and for the last 5 min of infusion and they were compared between groups. Results : The concentration of all three chromophores increased during infusion in the VP group (mean dHbT=1.03, CI95=0.84, P=0.058; mean dHbO=0.92, CI95=0.91, P=0.071; mean dHb=0.10, CI95=0.21, P=0.297). The HbT and HbO showed a substantially smaller increase in the placebo group (mean dHbT=0.31, CI95=0.74, P=0.22; mean dHbO=0.57, CI95=0.80, P=0.094) while the Hb decreased (mean dHb=-0.26, CI95=0.29, P=0.05). Comparing to the placebo group Hb increased significantly in the VP group (P=0.027) while the increase of HbO and HbT did not reach the level of significance (P=0.29 and 0.11). DSI showed a significantly larger increase in the VP than in placebo group (dDSI=25.8 CI95=8.8 [VP]; dDSI=3.3, CI95=3.7 [Placebo], P0.005). The CBFV and PI did not differ significantly between groups. (dVm=5.02.98 cm/s [VP], dVm=4.12.57 cm/s [Placebo], P=0.28; dPI=0.08 [VP], dPI=0.09 [Placebo]; P=0.47). Conclusion :VP increases cerebral perfusion and parenchymal oxygen extraction as well. The increased perfusion was indicated by NIRS and by TCD measurement of DSI while conventional velocity and pulsatility measurements failed to detect theses effects.
