Blood Flow

Jimmy Shea is spending a lot of his time cruising Lake Placid in his vintage mahogany speedboat, dubbed "Happy Ending" after his Olympic gold medal in skeleton three years ago. "It's my dream boat. It's classic, all redone," Shea said of his 1952 Century, its stern emblazoned with the Olympic rings. "It's beautiful." If only he could say the same about his sliding career.

According to the Bible, "A merry heart doeth good like a medicine." Now, modern science may be validating that Old Testament proverb -- a good laugh may actually help fend off heart attacks and strokes. "We believe laughing is good for your health," said Michael Miller, of the University of Maryland School of Medicine in Baltimore, who led the research. "And we think we have evidence to show why that's the case."

Marijuana users have faster blood flow in their brains, even after a month of not smoking, than nonusers, researchers have found. The study suggests that marijuana users have narrowed arteries, similar to patients with high blood pressure and dementia, and could help explain reports that heavy marijuana users have trouble on memory tests, said the researchers at the National Institute on Drug Abuse in Baltimore.

Coronary artery bypass surgery, which former President Clinton is scheduled to undergo, is often the treatment of choice for heart patients who have extensively clogged arteries or for those who are relatively young and desire a more maintenance-free procedure, experts said Friday.

An autopsy of a Corcoran State Prison inmate who bled to death in his cell overnight on Super Bowl Sunday showed that his medical shunt was not fully closed, allowing blood to flow out of his jugular vein, authorities said.

Large doses of caffeine are known to constrict blood vessels supplying the brain. Now researchers have found that going without the brew for about a day and half increases blood flow to the brains of heavy coffee drinkers 30% more than it does in light coffee drinkers. "It's way above what a person normally experiences," study coauthor Dr. Paul J. Laurienti says of the increased blood flow. The surge may explain the headaches that plague people when they first give up coffee.

Elderly people who drink moderately are less likely to suffer dementia than teetotalers, though seniors who drink too much add to their risk, researchers said Tuesday. Seeking to explain their findings, the researchers said consuming moderate amounts of alcohol prevents hardening of the arteries that leads to damaging strokes, lessens the risk of brain lesions and helps blood vessels to function.
Brandy Eddins, 14, lost her forearm in a wood-shop accident on Jan. 11. Later that day, in surgery at Hartford Hospital that went late into the night, Dr. Andy Caputo reattached the forearm, which had been cut midway between wrist and elbow. The difficult surgery was a technical success, and there was every reason to be optimistic. But when it comes to reattaching upper limbs--"replanting," in medical jargon--the body has evolved a response that even sophisticated medicine can't always overcome.
Among the directorial challenges Dave Barton faced in staging "Frankenstein in Love," a sometimes funny, sometimes philosophical but altogether gory play by horror master Clive Barker, was the careful, trial-and-error calibration of how much blood to spill. During rehearsals, Barton said, spectators in the front row of the Rude Guerrilla Theater Company's tiny Empire Theater were getting splashed. He gradually found ways to make the spurting more sparing.

J. Harold Wayland, 91, Caltech scientist known internationally for his research on blood flow. Wayland taught engineering and applied science at Caltech from 1949 to 1979. He was an expert on blood flow whose research examined the impact of diabetes mellitus on circulation and the interaction between blood and tissues in the smallest vessels in the body. He also pioneered the development of microscopic measurements to investigate fundamental life processes.
