* A typical square inch of body skin includes about 19 million cells, including an average of 625 sweat glands, 90 sebum or oil glands, 65 hair follicles, 19,000 sensory cells and about 12 to 13 feet of microscopic blood vessels. * Goose bumps are caused by smooth muscles that are concentrated around hair follicles. Under stimulation these muscles contract. This can be a reaction to cold or an evolutionary "flight or fight" response.

A heart blood vessel that was largely blocked caused the chest pains that put Gov. Jim Edgar in the hospital over the weekend, doctors said. The injury to the tiny blood vessel was characterized as a bruise to the heart that left no major or long-term damage. Dr. James Dove, president of the Prairie Heart Institute at St. John's Hospital, said the problem would be treated with medicine rather than surgery.

When 85-year-old Laker sportscaster Chick Hearn fell at home recently, hitting his head on concrete, he began hemorrhaging. Surgeons were unable to save him because pooled blood had damaged his brain. Like hundreds of thousands of Americans, Hearn took the blood-thinner Coumadin to protect against a stroke. But Coumadin makes bleeding hard to stop and, as a result, falls become riskier.

Researchers at UCI Medical Center are looking for 25 volunteers to participate in a study of a drug that may relieve a potentially debilitating leg condition. People with the condition, called intermittent claudication, experience aching, cramping and sometimes severe pain when they walk, but feel fine while at rest, research coordinator Judith Hopkins said. The symptoms are caused by atherosclerosis, a narrowing in the blood vessels due to plaque or fatty deposits.

A new approach to gene replacement therapy in animals and, eventually, in humans has been developed independently by two groups of researchers. The groups reported last week in the journal Science that they had used a special virus to insert the gene for a protein into cells isolated from the lining of blood vessels, then reintroduced the cells into pigs and dogs. The engineered cells then colonized the interior of blood vessels and began producing the new protein. In the past, researchers have speculated about using bone marrow cells, the source of blood cells, for gene replacement therapy.

The Food and Drug Administration on Thursday warned parents and pediatricians about the dangers of swallowing over-the-counter eyedrops and nasal decongestants by children age 5 and younger. The agency cited 96 cases of serious illness resulting from accidental swallowing of the products, with 53 hospitalizations. There were, fortunately, no deaths. The eyedrops, which are sold under a wide variety of brand and generic names -- including Visine, Opcon-A, Naphcon, Afrin, Dristan, Mucinex and Sudafed -- contain either tetrahydrozoline, oxymetazoline of naphazoline.

In her youth, my sister (who is not exactly a delicate flower) would sometimes faint. It was never quite clear why, and the episodes eventually passed. I was impressed. I couldn't even faint when I tried, and I did try once, in my teens. A pal devised a kind of "fainting recipe" that involved antics like rapid inhaling and exhaling. The antics didn't work.

Microsurgeons predict that within 15 years they will be able to perform routine operations on fetuses developing in the womb and to negate the need for transplant surgery by repairing hearts, kidneys and livers before returning the organs to the body. "Microsurgical research and techniques being developed around the world today will radically transform the health care profession and hospitals before the year 2000," said Dr. Sebastian Arena, director of Mercy Hospital's microsurgery laboratory.

A tiny diamond-tipped cutting tool spinning 200,000 times per minute successfully tunneled through deposits clogging arteries in 95% of 315 patients tested, scientists reported. "It has been an exceedingly useful device to treat blood vessels in a different way," said Dr. Maurice Buchbinder, a cardiologist at the University of California, San Diego. Side effects were minimal, Buchbinder said in a report at the annual meeting of the American College of Cardiology in Atlanta. Dr.

Chris Schwenke, the boxer who lapsed into a coma after losing on a technical knockout in a light-heavyweight fight July 22 at the Forum against Prince Mohammed, was taken off a respirator Friday, and doctors said he was no longer in a life-threatening situation. "His condition has gone from critical to guarded," said Christie Plank, spokeswoman for Daniel Freeman Memorial Hospital in Inglewood. Plank reported that Schwenke sat up with assistance later in the day, ate and talked.
