Dr. Lee Tyrey, an associate professor of obstetrics and gynecology, told scientists attending ELECTED—Or. E. Harvey Estes, professor and chairman of the Department of Community Health Sciences, has bron elected president of the North Carolina Medical Society. Dr. Josephine Newell, associate in community health sciences and director of the Breast Cancer Screening Project, has tieen named first vice president. the 59th annual meeting of the Endocrine Society in Chicago yesterday that THC suppresses secretion of luteinizing hormone (LH). LH is a chemical produced by the pituitary gland near the brain that causes delicate structures in ovaries to release eggs for fertilization, Tyrey explained in an interview before the meeting. It also helps to maintain another structure in the ovaries known as the corpus luteum that produces progesterone, a hormone that prepares the womb for receiving and nourishing the fertilized egg. Comparable To Smoking Marijuana "Because these studies included doses of THC comparable to what a human would be exposed to by smoking one or two marijuana cigarettes, we have to be concerned that the same thing might happen in humans," the scientist said. "At this point, we can't say that it does, but the possibility certainly rweds to be looked at." Tyrey's experiments were conducted on female laboratory rats that had had their ovjuies surgically removed. The ovaries were taken out, he said, because those organs can naturally limit the amoimt of LH produced by the pituitary, and the scientists wanted LH production to be at a maximum before injecting the rats with the marijuana derivative. After giving the aiumals varjring amounts cf THC, Tyrey and his staff took tiny blood samples from the rats' hearts through tubes entering the jugular veins of the animals. Hormone Suppressed Hormone measiuements showed that doses ranging from .5 milligrams per kilogram of body weight (mg/kg) to 8 mg/kg all suppressed the pituitary's rhythmic release of LH, he said; The length of the effect depended on the strength of the drug. "If this suppression occurs in rats with single injections, we wonder what the effect of chronic exposure would be," he said. "Can it prevent pregnancy from being established or can it cause eiirly abortion?" The scientist pointed out that birth control pills prevent pregnancy by reducing LH production. The research is continuing with rats that will have intact ovaries, Tyrey said. He also plans to study the long-term effects of THC on, the test aiumals. Federal Drug Administration regulations currently prohibit using THC in experiments wih women of childbearing age, the scientist said. GET SET TO TRAVEL Recent government statistics indicate that more than half of all American families take at least one vacation every year. Furthermore, each of those families travek an average of over 1,100 miles, according to the U.S. Travel Data Center in Washington, D.C.
