Methods It made a cerebral ischemia-reperfusion model using the line in the left middle cerebral artery occlusion (MCAO) of rats in ischemia for 2 h and reperfusion for l d, 4 d, 7 d and 14 d, the model of rats was established by intravenous injection of drugs. Nitric oxide synthase (NOS), endothelin-1(ET-1), 6-ketone-prostaglandin F<sub>1α</sub> (6-Ke-to-PG-F<sub>1α</sub>) and thromboxane B2 (TXB<sub>2</sub>) content of the brain microvessel in the lateral ischemic cerebral cortex was detected by enzyme immunoassay kits. Results In reperfusion for 4, 7 and 14 d, compared with model group, Zige lyophilized powder groups (16.40 mg/kg, 32.70 mg/kg and 65.40 mg/kg) had reduced significantly the level of TNOS, iNOS, ET-1, TXB<sub>2</sub> and TXB<sub>2</sub>/6-Ke-to-PGF<sub>1α</sub> in microvessel of the lateral ischemic cerebral cortex (<i>p</i> < 0.01), and had increased significantly the level of significantly cNOS and 6-Ke-to-PGF<sub>1α</sub>(<i>p</i> < 0.01). Conclusion Zige lyophilized powder for injection can improve the effect of cerebral microcirculation. Zige lyophilized powder can protect cerebral ischemia-reperfusion injury by improving the microvascular contraction function %K 梓葛冻干粉针 %K NOS %K ET-1 %K TXB< %K sub> %K 2< %K /sub> %K 6-Ke-to-PGF< %K sub> %K 1α< %K /sub> %K 脑微血管舒缩功能< %K br> %K Zige lyophilized powder for injection %K NOS %K ET-1 %K TXB< %K sub> %K 2< %K /sub> %K 6-Ke-to-PGF< %K sub> %K 1α< %K /sub> %K microvascular contraction function %U http://xbgjxt.swu.edu.cn/jsuns/html/jsuns/2017/6/201706004.htm
