Compound May Hold Clues to Prostate Cancer Prevention

Media Contact: Ann Blackford, (859) 323-6363

LEXINGTON, Ky. (April 30, 2007) − A University of Kentucky researcher has received funding to investigate an herbal compound used in Indian medicine that may have anti-prostate cancer mechanisms.

The National Institute for Health (NIH) has awarded Damodaran Chendil, assistant professor at the UK College of Health Sciences, Division of Clinical and Reproductive Sciences, $1.1 million to investigate the compound.

In previous studies, Chendil reported that the herbal preparation Rasagenthi Lehyam (RL), an herbal formulation used in Indian medicine, is an effective treatment for prostate cancer in an animal model. The most potent compound of RL is psoralidin, which proved to have more potent anti-cancer effects in prostate cancer cells compared to the other isolated compounds identified in RL. The action of psoralidin inhibits cancerous cell growth and tumor survival.

Importantly, Chendil found psoralidin targets cancer cells without causing significant toxicity to normal prostate cells.

The focus of Chendil's current research will be to study how psoralidin functions to inhibit the growth of prostate cancer cells and tumors. The results of the study may lead to the identification of biomarkers for prostate cancer and the development of chemotherapeutic and/or chemopreventive strategies for prostate cancer. Very little is known about psoralidin and Chendil's research is the first to study its action on prostate cancer cells.

"Treatment for cancer usually involves physically intense and expensive drug therapy, often with unwanted side effects," Chendil said. "Some scientists suggest that cures for cancer and other diseases can be found in nature and such treatments may produce less harmful side effects. I am excited about the potential this natural compound holds in helping to combat one of the most deadly cancers.

"Prostate cancer is the second leading cause of cancer-related deaths among men in the U.S. and many Western countries. African-American men have had higher incidence and at least double the mortality rates compared to men of other racial and ethnic groups.

Although early diagnosis of prostate cancer has improved significantly in recent years, there is a need for more effective treatment strategies for patients presenting with advanced or metastatic disease. Risk factors for prostate cancer include: age, since 65 percent of cases diagnosed occur in men over 65, race and family history of the disease.Symptoms of prostate cancer may include but are not limited to:

-Frequent urination, especially at night
-Difficulty or inability to urinate
-Painful or burning urination

Men who experience any of these symptoms are encouraged to seek advice from a urologist. For more information about prostate health, go to the UK Urology Prostate Cancer website

Reiki's Healing Touch

By Danielle Sonnenberg

Who says that hands alone can't heal? Undergo reiki, and you may see the possibilities of touch, from offering deep relaxation to restoring your energy. Reiki originated in Japan, but there is not one definitive story of how this alternative medicine was developed. Most believe Mikao Usui, a Japanese physician and monk, started the practice in the mid-19th century after a period of isolated meditation.

E*TRADE FINANCIALThe word reiki derives from rei, meaning universal life or spirit, and ki, or energy. Also known as qi or chi, this energy is believed to exist in all living beings, and has been addressed for centuries through traditional Chinese medicine and practices like acupuncture. Allegedly, qi's flow can be interrupted by negative thoughts and feelings; the blockage can then manifest itself in physical health problems.

But by placing their hands on or near a patient's body, reiki practitioners can manipulate this energy. Many positive effects -- including reducing stress and chronic pain, improving mental clarity and lowering one's heart rate -- are often reported.

Reiki can be practiced anywhere -- hospitals, alternative medicine clinics, spas or private homes. The sessions usually range from about 30 to 90 minutes. While the process itself is spiritual, it is important to remember that reiki is not a religious practice. It is also noninvasive, and very safe.
Usually the patient is fully clothed, and can either lie down or sit in a chair, whichever is most comfortable.

The hands are the sole instruments of this medicine, and they can be used on many parts of the body including the head, chest, abdomen or back for a few minutes at a time. If a patient is suffering from headaches or a cold, for instance, the practitioner may place his or her hands near the back of the head.

Most reiki does not involve actual touching, though. The hands are held at a distance, usually a few inches or more, from which the practitioner proceeds to manipulate the patient's energy. One of the most important aspects of the practice is the intent and a mindset of both people.
After the session, most patients feel very refreshed and some experience a warmth or tingling sensation.

Herb May Cure Bladder Infections

Forskolin, an herbal medicine made from the Asiatic coleus plant, may help treat urinary tract infection.
That’s according to preliminary tests done in mice.

The researchers who conducted those tests included Duke University microbiologist Soman Abraham, Ph.D.

They note that forskolin has been used for centuries in traditional Indian Ayurvedic medicine to treat various ailments, including painful urination.

The scientists tested forskolin in female mice with bladder infections caused by E. coli bacteria, which cause most urinary tractinfections.

Twenty-four hours after the mice were infected with E. coli, the researchers injected forskolin directly into the mice’s bladders or their belly.

For comparison, the scientists injected saltwater into the bladders of otherfemale mice with E. coli bladder infections.

One day after treatment, the mice in the forskolin group had less E.coli bacteria in their bladders than the mice that got the saltwatershot.

The forskolin group also had lower levels of inflammatory chemicals in theirurine, the study shows.

“This type of treatment strategy may prove beneficial for patients with recurrent urinary tract infections,” Abraham says in a Duke University news release.

He notes that antibiotics get rid of most bacteria that cause urinary tract infections, but some bacteria may hide in the bladder’s lining. Forskolin may force those hidden bacteria out of the bladder’s lining, where they could be targeted by antibiotics.

“Ideally, use of this herb would expel the bacteria, where it would then be hit with antibiotics. With the reservoir of hiding bacteria cleared out, the infection should not occur,” Abraham says.
The researchers didn’t test forskolin on people.
The study appears online in Nature Medicine.

Ginkgo Biloba? Forget About It

A history of the top-selling brain enhancer.

By Brendan I. Koerner

Remedies designed for the infirm seldom aid the healthy, too. Donning bifocals won't turn 20/20 eyesight into X-ray vision, and wearing a hearing aid can't endow a nonmusician with the gift of perfect pitch. It's a little baffling, then, that so many consumers assume ginkgo biloba will sharpen their memories.

Reputable medical researchers generally agree that ginkgo pills and powders, extracted from an ornamental tree whose seeds smell like rancid butter, show promise for treating Alzheimer's disease and other cases of age-related dementia. But scant scientific evidence supports the notion that ginkgo can also increase mental acuity among the young and fit. Even so, Nutrition Business Journal estimates that Americans spent $109 million on ginkgo in 2005, making it the nation's best-selling herbal brain booster, ahead of such rivals as gotu kola, Bacopa monnieri, and Siberian ginseng.

Native to East Asia, the ginkgo biloba tree likely existed during the Mesozoic Era; Charles Darwin referred to it as a "living fossil." Its seeds and leaves have been part of Chinese medicine for centuries, used to treat everything from coughs to bladder infections to unwanted freckling.
Though the ginkgo biloba tree has long been appreciated by American botanists, its medicinal properties were largely unheralded in the United States until the late 1980s. The same cannot be said of Europe, however, where German pharmaceutical company Dr. Willmar Schwabe GmbH & Co. launched its first ginkgo product, an extract formally called EGb 761, more than 30 years ago. Studies had shown that ginkgo was effective at increasing blood flow, so Schwabe marketed EGb 761, known commercially as Tebonin or Rokan, as a prescription medicine for the treatment of minor circulatory ailments. In 1988 alone, West German doctors wrote 5.24 million prescriptions for EGb 761 products.

As ginkgo's popularity increased throughout the 1980s, so, too, did the medical establishment's interest in its potential uses. Some practitioners of alternative medicine hailed ginkgo as an anti-aging remedy or as an antidote to kidney yang deficiency. Based on a study of 224 patients, one Berlin doctor pronounced ginkgo inhalations as the cure for the common cold. Dementia researchers, meanwhile, speculated that increased blood flow to the brain might help counter memory loss, a hypothesis lent credence by several small-scale West German and French studies.

Harvard University chemist Elias James Corey learned of ginkgo's promise in the late 1980s, and set his research team loose to synthesize ginkgo's active ingredient, ginkgolide B. They hoped the compound, once properly studied, could help treat toxic shock, asthma, and Alzheimer's disease. When Corey won the Nobel Prize in chemistry in 1990 for his work on organic synthesis, he name-checked ginkgolide B in his Nobel lecture, though nothing he said could be construed as an endorsement of its benefits.

Nevertheless, Corey's shout-out was a boon to Schwabe, which was just starting to market EGb 761 in the United States. Once relegated to obscure health-food stores, ginkgo broke mainstream. Schwabe first supplied EGb 761 to Nature's Way, an herbal products company based in Springville, Utah. (Utah is to supplements what Silicon Valley is to computers; Mormons are unusually keen on herbal remedies, thanks to Joseph Smith's doubts about conventional medicine.) Nature's Way sold EGb 761 as Ginkgold, the "World's #1 Selling Ginkgo." Though Ginkgold's packaging listed other benefits like its ability to reduce blood viscosity and protect against free radicals, the bold type first and foremost proclaimed it a mind sharpener. This marketing angle resonated with early 1990s health-food consumers, who were then obsessed with smart drinks and nootropics.

Virtually no peer-reviewed evidence supported Ginkgold's assertion that it could enhance memory in the otherwise healthy. But ginkgo's success in Europe, paired with Corey's inadvertent seal of approval, was enough to convince many consumers of the supplement's value. And since ginkgo was marketed as an over-the-counter supplement in the United States, the memory claim didn't need to be evaluated by the Food and Drug Administration. According to Nature's Way, Ginkgold would go on to outsell all other ginkgo biloba supplements combined in the United States. Schwabe was able to take a more direct roll in ginkgo's stateside sales starting in 1992, when it acquired a financial stake in Nature's Way; three years later, it obtained an American patent for EGb 761.

Meanwhile, clinical researchers (many funded by Schwabe) remained excited by ginkgo's potential in the fight against dementia. In 1997, a Schwabe-sponsored study published in the Journal of the American Medical Association concluded that EGb 761 "appears capable of stabilizing and, in a substantial number of cases, improving the cognitive performance and the social functioning of demented patients for 6 months to 1 year."

12 ESSENTIAL HERBS

By Michael Castleman

herbs safely and effectively.
By Michael Castleman

Do you use herbal medicine Whether or not youre aware of it, the answer is yes. Ironically, even vocal critics use medicinal herbs all the time usually without realizing it, says Mark Blumenthal, executive director of the American Botanical Council, a nonprofit herb education organization.
Thats because many foods have medicinal properties from ginger, which helps soothe upset stomachs, to garlic, which can help control cholesterol and reduce the risk of some cancers. Its also true that an estimated 25 percent of todays pharmaceutical drugs have plant origins. That includes aspirin, which originally came from white willow bark, and the cancer drug taxol, which is derived from the Pacific yew tree.

Herbs are also the most popular form of alternative medicine in the United States, according to a recent Harvard study which found that 38 million Americans collectively spend $4.2 billion on herbal medicine every year. Understanding more about how medicinal herbs work can help people treat common ailments more effectively.

Herbs Hiding in Plain Sight

One reason we dont recognize many herbal medicines is that theyre already so familiar to us. For example, coffee is an herbal medicine a powerful stimulant thanks to the caffeine it contains. In addition to being Americas favorite pick-me-up, coffee also opens your bronchial passages, according to botanist James Duke, author of The Green Pharmacy. Coffee can help treat the chest congestion of the common cold and asthma, Duke says. Recent studies show that coffee also may help prevent gallstones and Parkinsons disease, and that it boosts the pain-relieving power of ibuprofen.

Two other popular drinks, Coca-Cola and ginger ale, have medicinal uses both can calm upset stomachs. Coke, developed by Atlanta pharmacist John Pemberton in 1886, contains an extract of the tropical cola nut, which was widely used in the 19th century to improve digestion, reduce fatigue, strengthen the heart and even treat alcoholism. As for ginger ale, recent studies show that ginger helps prevent the nausea and vomiting of motion sickness.

Ginger is the herb for nausea, says Linda White, a physician and co-author of Kids, Herbs and Health. I use it and give it to my kids.

Then there are the herbs and spices in your kitchen. Before refrigeration, Blumenthal explains, they were mainstays of food preservation. Most culinary herbs and spices are useful not just for seasoning, but because they have antimicrobial properties that retard spoilage.

Using Herbs Safely

In the United States, herbal medicines are not regulated as strictly as pharmaceuticals because they are treated as foods, not drugs. Some critics contend that herb users are flying blind, but extensive research is available on many herbs. Two good sources for learning more about the latest research on herbal medicine are the American Botanical Council (www.herbalgram.org) and the Memorial Sloan-Kettering Cancer Center (www.mskcc.org).

Its also helpful to know that the number of adverse reactions attributed to herbs is relatively small. The American Association of Poison Control Centers publishes an annual review of the nations toxic exposures. In 2003 the most recent year for which complete figures are available acetaminophen (used in Tylenol and other painkillers) killed more than 100 Americans. For the same year, only seven deaths were blamed on the misuse of herbs. Although these deaths are tragic, it would be a mistake to suggest that medicinal herbs are a frequent cause of death.
Meanwhile, the U.S. Food and Drug Administrations strict regulation of drugs in no way guarantees their safety. University of Toronto researchers reviewed serious drug side effects among U.S. hospital patients from 1966 to 1996. The study did not look at overdoses or prescription errors, just at serious side effects from drugs taken as prescribed. The researchers estimated that more than 2 million hospital patients a year suffer serious side effects, and that more than 100,000 of them die.

All medicines should be used cautiously, and that includes herbal medicines. Just because theyre natural doesnt mean theyre safe, Blumenthal says. Some of the worlds most potent poisons are herbal for example, poison hemlock, which looks like parsley, and Amanita death cap mushrooms.

To use herbs safely, always take the following steps:

Tell your doctor which herbs you take and why. Do not substitute an herbal medicine for a prescribed medication without consulting your physician.

Pregnant women, children and those with chronic medical conditions should not take herbs or drugs without consulting a medical professional.

Do not duplicate drug effects with herbs. If you take a pharmaceutical antidepressant, dont take an herbal antidepressant, too.

Find out about any potential side effects before you begin taking the herbal medication. When using commercial preparations, follow the directions on the label.

Some herbs should not be taken before surgery because they slow blood clotting. Stop taking anticoagulant herbs notably garlic, ginkgo, ginseng and white willow at least two weeks before surgery.

Herbs for Wellness

Some herbs are beneficial to almost everyone when taken regularly. They include the following:
Garlic for Cholesterol Control and Cancer Prevention. Researchers at Penn State University gave men with high cholesterol either garlic or a placebo. The herb lowered their total cholesterol by 7 percent, which reduced their risk of heart attack by 14 percent. The majority of garlic studies show that garlic reduces cholesterol and helps prevent heart disease.

Garlic also helps prevent several types of cancer. In the Iowa Womens Health Study, researchers followed 41,387 middle-aged women for five years. Those who ate the most garlic had the lowest risk of colon cancer. In general, fruit and vegetable consumption helps prevent cancer, but in this study, of all the plant foods analyzed, garlic yielded the greatest preventive benefit. Other studies show that garlic also helps prevent prostate, esophageal, stomach and bladder cancer.

Dosage: Most studies have used approximately the equivalent of one clove a day. Garlic works best when its raw or only slightly cooked. Garlic supplements are another option (deodorized brands are available); they have similar cholesterol-lowering effects. Follow label directions.

Cautions: Garlic impairs blood clotting. If you notice increased bruising, stop taking it and consult a doctor. Stop taking medicinal doses of garlic two weeks before any planned surgery.

Ginkgo for Mental Sharpness. Ginkgo increases blood circulation through the brain, and it is best known for its potential to slow the progression of Alzheimers disease. Ginkgo also enhances memory in healthy adults of all ages, according to several studies. In one, the greatest memory enhancement occurred in those taking 120 milligrams once a day.

Dosage: Ginkgo leaves contain only trace amounts of the medicinal compounds. Use commercial preparations, which concentrate these compounds. Look for standardized extracts that contain 24 percent flavonoid glycosides. Take 120 milligrams daily.

Cautions: Ginkgo has an anticoagulant effect, so stop taking it at least two weeks before any surgery or if you notice bruising. Otherwise, side effects are rare, though upset stomach, headache and allergic reactions are possible.

Tea for Heart Health and Cancer Prevention. For centuries, tea was just considered a mildly stimulating beverage, but no longer. Both black and green tea are high in antioxidants, which help prevent both heart disease and cancer. A five-year Dutch study of 3,454 older adults showed that compared with nondrinkers, those who drank two cups of tea each day had a 46 percent less risk of heart attack.

Drinking tea also reduces cholesterol and improves survival odds after a heart attack. University of California at Los Angeles researchers surveyed 1,100 Asian women, half of whom had breast cancer. They found that those who were cancer-free drank the most tea. Japanese researchers have discovered that as breast cancer survivors tea consumption increases, their risk of recurrence decreases. Tea also appears to protect against cancers of the colon, rectum, pancreas and esophagus.

Note: Both green tea and black tea come from the leaves of the same plant. Drying the leaves produces green tea. Fermenting them yields black tea. Both green and black tea help prevent heart disease and cancer, but for reasons that remain unclear, only green tea has been shown to reduce the risk of breast cancer.

Dosage: One to four cups a day, or as much as you can tolerate. A cup of tea has approximately half the caffeine of a cup of instant coffee, and one-third the caffeine of a cup of brewed coffee.
Cautions: Tea contains caffeine that may cause insomnia and irritability.

Herbs To TreatCommon Complaints

Although herbal medicine is not the answer for every ailment, herbs can be used effectively to treat many health conditions, including those below.

Black Cohosh for Menopausal Discomforts. For 40 years, Europeans have used black cohosh to treat hot flashes. During the past decade, this herb has become popular in the United States.

Several studies have questioned its benefit, but a clear majority have shown that black cohosh is effective. Its also safe for women who cant take hormones, such as those with a history of breast cancer.

Dosage: Products vary, so follow the label directions.

Cautions: Side effects are rare, but may include stomach distress. Black cohosh should not be used by pregnant women.

Cranberry for Urinary Tract Infection. Cranberry juice and the dried berries and extract prevent bacteria from sticking to the bladder wall long enough to cause infection. Many studies confirm cranberrys value in preventing urinary tract infection. Canadian researchers gave 150 women one of three treatments: cranberry juice (three cups per day), cranberry tablets (three per day) or a placebo. A year later, the women who took cranberry had experienced significantly fewer infections than the placebo group. Cranberry juice and dried cranberries are available at supermarkets. Capsules containing cranberry extract are available at health food stores and most pharmacies.

Dosage: If you use cranberry juice cocktail, drink at least three cups a day. If you use dried cranberries, munch on a handful or two a day. For commercial cranberry extract, be sure to follow the label directions.

Cautions: None.

Echinacea for Colds. The root and sometimes the aboveground portions of this daisylike flower have been shown to bolster the immune system and help the body fight colds. Some studies have shown no treatment benefit, but most show that echinacea minimizes cold symptoms and speeds recovery. The most comprehensive investigation of echinaceas cold-fighting effectiveness was a University of Wisconsin analysis of nine studies. Eight showed significant treatment benefit milder symptoms and briefer colds.

Dosage: Take the dosage recommended on the product label. Typical directions are to take it several times a day at first, and then taper off as you begin to feel better. Echinacea is available in teas, capsules and tinctures.

Cautions: A mildly upset stomach is possible with the tincture. Echinacea is safe for most people, but because it stimulates the immune system, it is not recommended for those with auto- immune diseases (rheumatoid arthritis, lupus and several others), or for transplanted-organ recipients. It should also be avoided by those allergic to closely related plants, such as chamomile and ragweed.

Ginger for Motion Sickness and Morning Sickness. Australian researchers gave 120 pregnant women either a placebo or capsules containing 11/2 grams of ginger powder. From the first day of treatment, the ginger group experienced significantly less nausea. Several studies show that the herb also wards off motion sickness. Danish researchers tested it on 80 naval cadets in heavy seas. Compared with those who took a placebo, the ginger group experienced 72 percent less seasickness. To keep motion sickness at bay, take a capsule containing 1,000 milligrams of powdered ginger root about an hour before you embark, and every two hours during your journey.

Dosage: Start with 1,000 milligrams. If that doesnt provide sufficient relief, try 1,500 milligrams. You can also brew ginger tea using 2 teaspoons of fresh grated root per cup of boiling water, or drink ginger ale just check the label to make sure it contains real ginger and not artificial flavoring.

Cautions: Some people report heartburn after taking ginger capsules.

Horse Chestnut Seed Extract for Varicose Veins. Because of genetics, aging or long periods of standing, the walls of leg veins can weaken. Blood pools in the calves and fluid leaks into surrounding tissue, causing unsightly varicose veins. Horse chestnut seed contains a compound (aescin) that strengthens vein walls, which decreases this fluid leakage. Several studies show that its an effective treatment for varicose veins. German researchers gave 240 people with varicose veins either compression stockings or horse chestnut (50 milligrams of aescin twice a day). After 12 weeks, both groups experienced equal relief.

Dosage: Studies showing benefits have used 50 milligrams of aescin once or twice a day.
Cautions: Horse chestnuts from the tree are toxic: Ingestion has killed children. Commercial extracts are detoxified and safe.

Milk Thistle for Liver Disease. Mainstream medicine doesnt have any miracle drugs for liver disease (hepatitis, cirrhosis), but milk thistle seeds can help. They contain three compounds collectively known as silymarin that have a remarkable ability to protect and heal the liver.

Italian researchers have shown that milk thistle speeds recovery from hepatitis. Several studies have shown that the herb helps treat alcoholic cirrhosis. Milk thistle also helps prevent liver damage from powerful drugs. Most remarkably, this herb has been shown to treat Amanita mushroom poisoning better than mainstream medical treatments. Swiss researchers analyzed 452 cases of mushroom poisoning. Among those who received standard treatment, 18 percent died. But among those treated with silymarin, the death rate was only 10 percent.

Dosage: A typical recommended dosage is 140 milligrams of silymarin three times a day.
Cautions: Side effects are rare, but can include headache, stomach distress, nausea, hives, itching and joint pain.

St. Johns Wort for Depression. While some studies suggest otherwise, the vast majority show that St. Johns wort, in capsules or tablets, works as well as Prozac and Zoloft for relieving mild to moderate depression. Researchers in Montreal gave 87 depression sufferers either the herb (900 to 1,800 milligrams/day) or a standard dose of Zoloft (50 to 100 milligrams/day). After 12 weeks, both groups showed the same mood elevation based on standard psychological tests.

However, the herb caused fewer side effects. Furthermore, a German study shows that the herb is as effective as Prozac but with fewer side effects. Twenty-three percent of those in the Prozac group experienced significant side effects, but in the herb group, only 8 percent reported serious side effects.

Dosage: Follow label directions. Studies showing benefits have used 600 to 1,800 milligrams/day. Most studies have used 900 milligrams/day.

Cautions: St. Johns wort can cause an upset stomach, increases sensitivity to sunlight and reduces the effectiveness of birth control pills. It also interacts with many other drugs, possibly reducing their effectiveness. If you take medication regularly, its important to consult your physician or pharmacist before using St. Johns wort.

Valerian for Insomnia. Valerians centuries-old reputation as a sleep aid has been validated by many studies. It often works as well as a pharmaceutical sleeping aid. German researchers gave 202 chronic insomniacs either valerian or a pharmaceutical sedative. After six weeks, both treatments were equally effective. But unlike many sleeping pills, valerian is not addictive.
Dosage: Follow label directions.

Cautions: Raw valerian root smells and tastes terrible. Use a commercial preparation. Some include other safe tranquilizing herbs such as hops or lemon balm.

Vitex (chaste tree berry) for PMS. Ripe seeds from Vitex angus castus, also called chaste tree, help balance levels of estrogen and progesterone, which minimizes the mood swings, breast tenderness and bloating of premenstrual syndrome. Many studies have found that chaste tree is effective. When 1,634 German PMS sufferers took the herb for three months, 93 percent reported relief from mood upsets. In tests that recorded two other popular PMS treatments vitamin B6 and Prozac chaste tree worked almost as well as the popular antidepressant and better than the vitamin.

Dosage: Available in pills, capsules and tincture. Follow label directions.

Cautions: Some women report stomach distress, headache and increased menstrual flow. Should not be used by pregnant women.

ALTERNATIVE MEDICINE -- Finding magnets attractive

By DERRIK J. LANG - The Associated Press

Magnetic kneepads. Magnetic insoles. Magnetic hairbrushes. Magnetic bed sheets.

You may have seen these alternative pain-relieving products online, or heard your grandmother raving about such remedies. But do they work?

QUESTION: Can magnets cure ailments?
---
ANSWER: Research findings so far do not firmly support claims that magnets are effective for killing pain, according to the National Center for Complementary and Alternative Medicine.
However, that doesn't mean they're totally without use in medicine.

Magnets have been used in surgery to remotely direct instruments. And Robert Campbell, a pharmaceutical sciences professor at Northeastern University's Bouve College of Health Sciences in Boston, recently developed a way to deliver drugs to better attack malignant tumors using external magnets.

In the laboratory, Campbell found that using an external magnet helps chemotherapeutic drugs get to the tumor and stay there longer.

"The magnets that we're using are small, not bigger than a dime," he says.

Really? So does this mean you can grab one off your fridge and use it when you've got a boo boo?
Nope. The magnets Campbell has been using in his cancer research are about 100 times stronger than the household variety - or those found in magnetic kneepads, insoles, hairbrushes and bed sheets.
