Research suggests that treatment with human growth hormone may reverse some of the effects that aging has on the body. Injecting a genetically engineered version of the natural body hormone led to an increase in muscle mass and a decrease in body fat in a group of men ranging in age from 61 to 81 years old. However, the results are preliminary, and the long-term effects of human growth hormone have yet to be determined.

Drug maker Eli Lilly & Co. agreed to pay at least $300 million for Monsanto Co.'s Posilac, a synthetic hormone used to boost milk production in cows. The agreement will expand Lilly's veterinary operations and enable St. Louis-based Monsanto to focus on genetically modified crops. Lilly, based in Indianapolis, gains the U.S. sales force for Posilac and the manufacturing plant in Augusta, Ga. It also inherits opposition to the hormone from consumer advocates and some dairy processors.

Scientists call it the love hormone, the chemical that binds people to one another. Now researchers from the University of Zurich in Switzerland have found that the hormone, released in high amounts in mothers after childbirth, can improve a person's ability to interpret what is going on in another person -- by reading information gleaned from their eyes.

Smoking gives post-menopausal women higher levels of two male hormones, suggesting that the hormones might account for the higher incidence of heart attacks among women smokers, researchers at UC San Diego say. The findings also point to hormones as the potential explanation for why men are three times more likely than women to have cardiovascular disease.

The startling finding that a popular hormone therapy used to treat menopause and prevent osteoporosis may promote breast cancer left many women wondering this week whether they should reconsider taking so-called replacement hormones. The finding, announced Tuesday in Sweden, emerged from a study of women over age 34 who took hormones for at least six years. While estrogen alone had a slight impact on their risk of breast cancer, estrogen and progestin together raised it fourfold.

Some binge eaters produce unusually small amounts of a hormone that ordinarily signals people that they are full, according to a study. The report suggests that a defect in production of this natural chemical may be an underlying cause of bulimia nervosa, an eating disorder in which people stuff themselves with food and then make themselves vomit. The study compared 14 women with bulimia to 10 healthy volunteers.

Hormone replacement therapy should not be given to women solely for the purpose of preventing heart disease because the benefits are ambiguous at best, the American Heart Assn. recommended today. The suggestion from the nation's leading group of heart doctors adds another twist to the complex calculations faced by many of the 50 million American women over age 50 as they ponder whether to use hormone therapy.

A new strain of midget mice that are only half normal size has been developed by Ohio University researchers who accomplished the feat by modifying the gene for a growth hormone and inserting it into the animals, the scientists report today. The researchers say the technique should work for any animal, so it should be possible to develop small rodents, pigs and other laboratory animals that would require less space and food.

In the latest indictment of hormone replacement therapy, researchers at the Fred Hutchinson Cancer Research Center in Seattle have found that women taking an estrogen-progestin combination have an increased risk of ovarian cancer. The women also underwent more endometrial biopsies for the diagnosis of cancer, according to the report in the Journal of the American Medical Assn. Despite the increased risk, however, ovarian cancer remains a rare disease, the researchers said.
