    The patient didn’t overdose on medication. She overdosed on grapefruit juice. The 42-year-old was barely responding when her husband brought her to the emergency room. Her heart rate was slowing, and her blood pressure was falling. Doctors had to insert a breathing tube, and then a pacemaker, to revive her. They were mystified: The patient’s husband said she suffered from migraines and was taking a blood pressure drug called verapamil to help prevent the headaches. But blood tests showed she had an alarming amount of the drug in her system, five times the safe level. Did she overdose? Was she...

    Citrus species are among the most important fruit trees in the world. Citrus has a long history of cultivation, often thought to be more than 4,000 years. Until now, however, the exact genetic origins of cultivated citrus such as sweet orange (Citrus sinensis), lemon (C. limon), and grapefruit (C. paradisi) have been a mystery. A team of researchers from China has published a study in the Journal of the American Society of Horticultural Science that provides genetic evidence of the origins of a variety species of today's cultivated citrus. The research team, led by Zhiqin Zhou from Southwest University, analyzed...

    Scientists have shown that feeding a simple polyamine called spermidine to worms, fruit flies and yeast significantly prolongs their lifespan. In addition, adding spermidine to the diet of mice decreased molecular markers of ageing, and when human immune cells were cultured in a medium containing spermidine, they also lived for longer.Spermidine - a simple linear molecule found in large quantities in human sperm and grapefruit - is known to be necessary for cell growth and maturation, and as cells age their level of spermidine is know to fall. Now, Frank Madeo from the University of Graz in Austria and his colleagues have shown...
  • Nabbed: Culprit Of Grapefruit Juice-Drug Interaction

    Nabbed: Culprit of grapefruit juice-drug interaction Ben Harder Drinking grapefruit juice is a medical no-no for people who take any of several widely prescribed drugs. The drink affects how the body metabolizes the medications. Now, researchers have pinned down the class of natural juice compounds that's responsible for the unwanted chemical interaction. Researchers discovered around 1990 that grapefruit inhibits the enzyme CYP3A4, which participates in the metabolism of about half of all prescription drugs. Inhibition of that enzyme causes drugs to stay in the body longer, potentially overdosing the patient. Doctors subsequently advised many patients not to consumer the juice...

    In 1989, a group of Canadian researchers studying a blood pressure drug were astonished to discover that drinking a glass of grapefruit juice dangerously increased the drug's potency. They were testing the effects of drinking alcohol on a medicine called Plendil. The scientists needed something that would hide the taste of alcohol so that subjects would know only that they were taking the drug and not know whether they were drinking alcohol with it. "One Saturday night, my wife and I tested everything in the refrigerator," said David G. Bailey, a research scientist at the London Health Sciences Center in...
  • Germ Sours Florida Citrus Industry

    FORT PIERCE, Fla. — For more than 40 years, grapefruit grew juicy and ripe on this 1,200-acre grove inland from the Atlantic. Now there is little left but the jagged branches of torn-up trees, and spicy smoke fills the hot midday air as one by one, they are burned to powdery ash. Last year's hurricanes dropped a bacteriological bomb on Florida's already sorely challenged citrus industry, widely dispersing a virulently contagious germ that causes citrus canker — a disease harmless to humans and animals but ruinous to oranges and grapefruit. Florida officials say the possibility that hurricanes could further scatter...

    Grapefruit diet really works, say scientists in US By Celia Hall, Medical Editor (Filed: 29/01/2004) The famous grapefruit diet espoused by women across the Western world 30 years ago really does work, according to research from America. A three-month study has shown that adults who ate half a grapefruit with each normal meal, three times a day, lost 3.6lb on average compared with people eating a similar diet without grapefruit who lost only 0.5lb. Some of the grapefruit eaters lost as much as 10lb and even grapefruit juice had an effect. A group who drank juice lost, on average, 3.3lb....

    For education and discussion only. Not for commercial use. TALLAHASSEE, Fla. -- Cutting crews can resume chopping down healthy citrus trees within 1,900 feet of those infected with canker under a bill signed into law Monday by Gov. Jeb Bush. Despite protests from homeowners, the bill moved quickly through the House and Senate and crews expected to remove another 200,000 trees this year. "We've got to look at the overall economic impact on our state and move forward," said Bush spokeswoman Elizabeth Hirst. Agriculture brings in $9 billion a year in central Florida and employs more than 100,000 people. The...

    For education and discussion only. Not for commercial use. VERO BEACH, Fla. -- The U.S. Food and Drug Administration served a warrant on an Ocean Spray Cranberries Inc. citrus processing plant but wouldn't publicly say why. FDA spokeswoman Kimberly Rawlings said Friday that the investigation of the Vero Beach plant is ongoing and she could not discuss details. Rawlings, with the FDA's Center for Food Safety and Applied Nutrition, said the warrant was served Thursday. The plant manager referred calls to Ocean Spray headquarters in Lakeville-Middleboro, Mass. Chris Phillips, a spokesman for the agricultural cooperative, said the company is cooperating...
