Objective : Acupuncture and herbal medicine have been used to prevent and treat cerebrovascular accident, such as stroke, and many studies of acupuncture and moxibustion concerning stroke have been undertaken in humans and various animals. However, the protective effect of the electroacupuncture (EA) of Huan-do (GB30) on the transient forebrain ischemia injury has not been published. Methods : The nenroprotective effects of EA (2 ms, 10 Hz, and 1 - 2 mA) of GB30 on the transient forebrain ischemia injury were investigated by immunohistochemistry of c-Fos-like protein in Sprague-Dawley rats. Results : The transient forebrain ischemia injury resulted in increased expression of c-Fos-like protein (cFL) in the dentate gyms (DG) and CAl for 6 hrs after ischemia, and EA increased significantly expression of cFL in the CAl and DG. For 48 hrs after, there was delayed expression of cFL at the CAl and DG, representing the sign of neuronal cell death, but EA decreased the delayed expression of cFL, significantly. Conclusion : These results suggest that the nenroprotective effects of EA on transient forebrain ischemia injury may be related to excitatory regulation of cFL at the early stage and inhibitory regulation in the long term.
