摘    要:小檗碱5,10,20mg·kg-1ip可显著延长双侧颈总动脉结扎致脑缺血小鼠的存活时间。自颅外阻断大鼠大脑中动脉造成局灶性脑缺血模型。小檗碱20,40mg·kg-1于术前中,能缩小缺血2h造成的梗塞范围,减轻神经功能障碍.小檗碱40mg·kg-1ip能提高大鼠急性脑缺血30min时的血浆,海马及皮层脑组织的超氧化物歧化酶活力。降低丙二醛含量。结果表明。小檗碱对缺血脑组织有保护作用。其机理推测与其抗氧自由基损伤有关.

关 键 词:小檗因类  脑缺血  超氧化物歧化酶类  脑梗塞

Abstract:erberine(Ber 5,10、20mg·kg-1,ip)significantly prolonged the survial time of micesubjected to cerebral ischemia by the occlusion of thebilateral carotid arteries. The mortality of the mice sub-jected to reperfuSion after cerebral ischemia was re-duced by Ber After acute incomplete cerebral ischemiain rats induced by hypotension coupled withhypoperfusion for 30 min, Ber (40 mg·kg -1 ip) mightmarkedly increase the activities of superoxidedismutase and decrease the concentration ofmalndialdehyde in plasma,as well as in hipocampusand cortex of the brain.in the model of local cerebralinfarction of rat produced by middle cerebral arteryocclusion,Ber(20, 40 mg·kg-1,ip before operation)decreased the infarct size and ameliorated neurologicdeficits,improved electroencephalogram changes in 2h occ1usion of rats.
Keywords:berberine  cerebral ischemia:superoxide dismutase  cerebral    infarction
