Abstract

The purpose of this study was carried out to investigate the effect of electroacupuncture on reactive gliosis expressing GFAP in rat with transient global cerebral ischemia. Subjects were randomly divided into two groups, a control group and a electroacupuncture group on ST36, LI11 and SP9 with 2 Hz and 1 mA. The rats were sacrificed on 1, 3 and 7 days after transient cerebral ischemia using ligation of left common carotid artery. After making brain slide sections, they were immunostained with GFAP antisera(1:2,500). The results were as follows: The numbers of astrocytes of electroacupuncture group were decreased than those of control group at every 1, 2 and 7 days. Especially, the numbers of astrocytes at 3 days(p<0.01) and 8 days(p<0.05) were different statistically. And astrocytes had resting, hypertrophic and moving types on cerebral cortex. The decrease of numbers of astrocytes expressing GFAP showed that electroacupuncture could localise and minimize the brain damage by transient cerebral ischemia and cause brain cell plasticity.
