초록
Objectives : Cnidium officinale(CO) has been used for medication for stroke in the Oriental Medicine. So this study was planned to investigate the effects of CO on the focal ischemia-induced by Middle Cerebral Artery Occlusion(MCAO) in rats Materials and methods : The focal ischemia was induced by MCAO. CO extracts through oral administration and herbal acupuncture at GB2l was carried out during 3 weeks after focal ischemia-induced. Eight-arm radial maze was used for the behavioral task. For the neuroprotective effect of CO, we investigated AchE, ChAT, and NGF-expression by immnohistochemical method. Results : The error rate in the eight-arm radial maze task was significantly decreased in normal group compared to control group on 1-6days, OA-CO1(CO oral administration, 0.8g/kg) group on 1-6days, OA-CO2(CO oral administration, 1.6g/kg) group on 1-3,5,6days, HA-CO1(CO herbal acupuncture, 0.016g/kg) group on 2,3,6days, HA-CO2(CO herbal acupuncture, 0.008g/kg) group on 1-3,5,6days. The rate of correct choice was significantly increased in OA-CO1, HA-CO2. The density of neurons in the hippocampal CA1 was the most increased in OA-CO1, HA-CO1, HA-CO2. The density of ChAT in the hippocampal CA1 was increased in OA-CO1, HA-CO2. The density of ChAT in the hippocampal CA1 was significantly increased in OA-CO1, HA-CO2. The density of NGE in the hippocampal CAI was significantly increased in OA-CO1, OA-CO2, HA-CO2. Conclusions : These results suggest that CO oral administration with 0.8g/kg and CO herbal acupuncture with 0.008g/kg might be used as a regulator of cell death of cholinergic system induced by stroke.
