>New clue explains damage of stroke

Friday, September 17, 2004

A new study has linked brain cell damage during a stroke to an increase in
brain acidity, a finding that could lead to new therapies for stroke
victims.
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) <
