Abstract

Objectives : Angelicae Radix, the root of Angelica gigas N_AKAI (Umbelliferae) , which has been used to nourish the blood(補血), regulate menstruation(調經), relieve pain and promote bowel movements(崩漏) and activate blood circulation for the treatment of fatigue, headache, constipation and blood troubles in traditional Korean medicine. It's flavour and channel tropism is sweet(甘), pungent(辛), warm(溫), acting on the lung, heart and spleen(肺, 心, 脾). The purpose of study we report here was to determine the neuroprotective effect of Angelica gigas on global ischemia induced by 4-vessel occlusion in Wistar rats. Methods : Angelica gigas extracts was lyphilized after extraction with 85% methanol. We induced 4-VO for 10 minutes and reperfused again. The number of CA1 pyramidal neurons were counted after 7 days of reperfusion under the cresyl violet staining. Results : The results showed that Angelica gigas had significantly neuroprotective effects (100, 250 and 500mg/kg of AR extracts, p＜0.001) compared with control group. Each neuroprotective ratio was about 66.1, 79.3 and 78.6% respectively. Immunohistochemical data partially explained the protective effects of Angelica gigas via attenuation of COX-2 induction in hippocampus. Conclusion : Angelica gigas gas neuroprotective effects on the global ischemia induced by 4-vessel occlusion in Wistar rats and the attenuation of COX-2 induction is thought to be its possible mechanism.
