目的:探讨超声微泡辅助治疗对大鼠脑缺血再灌注损伤的治疗效果.方法:采用线栓法制备大鼠脑缺血再灌注模型,取造模成功的 40 只大鼠随机分为微泡组(超声辐照+微泡+溶栓)和对照组(超声辐照+溶栓)各 20例.2 组大鼠均以 1 次·d-1 的频率接受治疗,持续治疗 15 d.溶栓治疗结束后,比较 2 组血栓清除评分、神经损伤严重情况、脑组织含水率.结果:分组后 3、6 h微泡组血栓清除评分高于对照组(P<0.05);分组后 10、15 d微泡组改良神经功能缺损评分(modified neurological severity scores,mNSS)评分均低于对照组(P<0.05);分组后 8 d,微泡组脑组织含水率低于对照组(P<0.05).结论:超声联合微泡用于脑缺血再灌注大鼠,有助于血栓的清除,能够减轻神经损伤及脑组织含水率.
Objective:To explore the therapeutic effect of ultrasound microbubble-assisted therapy on cerebral ischemia-reperfusion injury in rats.Methods:A rat cerebral ischemia-reperfusion model was prepared by the wire thrombus method.40 successfully modeled rats were randomly divided into a microbubble group(ultrasound irradiation+microbubble+thromb olysis)and a control group(ultrasound irradiation+thrombolysis),with 20 cases in each group.Both groups of rats received treatment at a frequency of 1 times·d-1 for 15 days.At the end of thrombolysis treatment,thrombus clearance scores,severity of neurological damage,and water content of the brain tissue were compared between the two groups.Results:Thrombus clearance score in the microbubble group was higher than that in the control group at 3 and 6 h after grouping(P<0.05).mNSS scores in the microbubble group were lower than that in the control group on the 10th and 15th day after grouping(P<0.05).The water content of brain tissue in the microbubble group was lower than that in the control group on the 8th day after grouping(P<0.05).Conclusion:Ultrasound combined with microbubbles for cerebral ischemia-reperfusion rats contributes to thrombus clearance and is able to attenuate neurological damage and brain tissue water content.
