Objectives: This study was performed to investigate the effects of acupuncture therapy(AT, AT-9), electro-acupuncture therapy(EAT) and low level laser acupuncture therapy(LAT) at LRJ on the focal ischemia-induced by intraluminal filament insertion in rats. Methods : In the present syudy, the focal ischemia was induced by Intraluminal filament insertion into left middle cerebral artery. The subjects were divided into five groups after focal brain ischemia. (n=15, in each group) : Control with no treatment, AT with acupuncture at $LR_3$, AT-9 with acupuncture at $LR_3$ and rotating 9 times in a clockwise direction, EAT with electro-acupuncture at $LR_3$ and LAT with invasive laser acupuncture at $LR_3$. Anti-apoptotic and neuroprotective effects of acupuncture were observed by mGluR5 mRNA, Bax mRNA, Bcl-2 mRNA, Cytochrome C protein, Cresyl violet-stain and Choline acetyltransferase (ChAT)-stain in the hippocampus. Results: 1. In LAT, mGluR5, Cresyl violet-stain and ChAT-stain were increased. 2. In LAT, Cytochrome C protein was decreased. 3. In AT-9, Bax, Cytochrome C protein and the Bax/Bcl-2 ratio were decreased. 4. In AT-9, Bcl-2, Cresyl violet-stain and ChAT-stain were increased. 5. In EAT, Bcl-2 and Cresyl violet-stain were increased. Conclusions: These results suggests that LAT and AT-9 show anti-apoptotic and neuro-protective effects and that LAT and AT-9 may be useful for managing stroke by focal brain ischemia.

Bambusae Caulis in Liquamen(BCL) has been commonly prescribed for stroke patients in the traditional Oriental medicine. So this study is aims to investigate the anti-apoptotic and neuroprotective effects of Bambusae Caulis in Liquamen(BCL) manufactured by different production process on the focal ischemia induced by intraluminal filament insertion in rats. The focal ischemia was induced by intraluminal filament insertion into middle cerebral artery. The animals were divided into four groups (n=15 in each group). The ischemia induced and not treated group : Control group, the ischemia induced and oral medication of the three kinds of BCL : BCL-A group, BCL-B group, BCL-C group. BCL-A was produced by heating at a low temperature$(250^{\circ} C)$ in electric kiln and filtering. BCL-B was produced by heating at a high temperature$(900^{\circ} C{\sim}1,000^{\circ}C)$ in yellow earth kiln and refining and filtering. BCL-C was produced by heating at a low temperature$(400^{\circ} C)$ yellow earth kiln and no refining and filtering. The anti-apoptotic and neuroprotective effects of the oral medication of BCL were observed by Bax, BCL-2, cytochrome c, mGluR5, cresyl violet and ChAT-stain. Our study suggests that BCl-A(was produced by heating at a low temperature in electric kiln and filtering) and BCL-C(was produced by heating at a low temperature in yellow earth kiln and no refining and filtering) show anti-apoptotic and neuroprotective effects on the focal ischemia induced by intraluminal filament insertion in rats and BCL-C is more effective than BCL-A.
