During a stroke, acid is released in the brain following the depletion of oxygen in brain cells, say researchers at the Robert Dow Neurobiology Laboratories in Portland, Oregon. That acid release causes a subsequent influx of calcium into the nerve cells, which sets off a cascade of events toxic to the cells, lead researcher Zhi-Gang Xiong said. How brain damage can be reduced The researchers found in experiments with rats that brain damage could be reduced through treatment with a chemical that blocked nerve perception of the increase in acidity. Rats injected with the agent showed a 60 percent reduction in the area of brain damage, the researchers reported. The study appears in the Sept. 17 issue of Cell. - (HealthDayNews) < Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=24658
