Stroke patients treated with the new stroke drug tissue plasminogen activator (t-PA) generally have better outcomes and therefore are less costly to the health care system than those not treated, according to an article published in the April issue of Neurology, the scientific journal of the American Academy of Neurology.
For the first time in medical history, researchers have transplanted fetal brain cells from pigs into humans to treat a degenerative disease of the brain. Fetal pig cells have been transplanted into several patients who suffer from Parkinson's Disease. Results of this research will be presented at the Annual Meeting of The American Association of Neurological Surgeons (AANS) on Monday, April 27, 1998 in Philadelphia.
A surgical procedure performed to remove the fatty build-up in the carotid arteries leading to the brain has proven to reduce the risk of stroke. Stenosis, or blockage, in the carotid artery narrows the pathway for blood to travel to the brain. This build up can break off and block the flow of blood to the brain completely, causing a stroke and the ensuing brain damage.
The American Association of Neurological Surgeons (AANS) will hold its 66th Annual Meeting April 25 - 30, 1998 at the Pennsylvania Convention Center in Philadelphia, Pennsylvania.

Results of this landmark study, conducted in a rabbit model of rheumatoid arthritis, appear in the April 15 issue of the Proceedings of the National Academy of Sciences. It is a major advance in the quest to bring arthritis gene therapy into widespread clinical use.
