摘要: 目的:考察逐瘀通脉胶囊对大鼠急性局灶性脑缺血再灌注损伤的影响。方法:SD大鼠按体重随机分为7组:模型组(局灶性脑缺血损伤模型)、维脑路通组(100 mg·kg-1,阳性对照1)、脑心通组(800 mg·kg-1,阳性对照2)、逐瘀通脉200、100、50、25 mg·kg-14个剂量组。经口给予上述剂量受试物7 d,模型组经口给予去离子水,末次给药30 min后采用改良线栓法建立大鼠急性局灶性脑缺血损伤模型。造模后24 h内,观察大鼠清醒后出现的神经行为异常,按Zea Longa方法进行评分。测定血清中凝血酶原时间、超氧化物歧化酶、丙二醛,分析脑梗死体积,计算脑梗死体积比和脑梗死减少率。结果:与模型组比较,逐瘀通脉200、100、50、25 mg·kg-1各剂量组神经行为异常明显改善,脑梗死体积、脑梗死体积比均显著下降,脑梗死率显著减少。逐瘀通脉50~200mg·kg-1可显著延长凝血酶原时间和升高超氧化物歧化酶水平。逐瘀通脉胶囊对脑梗死各个检测指标的影响略优于阳性对照药维脑路通、脑心通。结论:逐瘀通脉胶囊对大鼠急性局灶性脑缺血再灌注损伤有预防性保护作用。

Abstract: Objective:To study the effects of Zhuyutongmai capsule on acute focal cerebral ischemia reperfusion injury in rats. Methods:SD rats were divided into 7 groups, that were model control, positive control (Weinaolutong 100mg·kg-1, Naoxintong 800 mg·kg-1) and Zhuyutongmai (200、100、50、25 mg·kg-1). The drugs were infused into rat stomachsfor 7 days by intragastric administration, the rats of model group were given deionized water. After 30 min of the last administration, improved suture method was adopted to establish acute focal cerebral ischemia reperfusion injury in rats. In 24 hours, the rats awake were observed what the neurobehavioral abnormalities were,and wererated according to the Zea Longa rating method. The blood PT, SOD and MDA were tested. The frontal cerebral infarction volumes were analyzed. The ratios of cerebral infarction and cerebral infarction decrement were calculated. Results:Compared with model group, the nerve behaviors of Zhuyutongmai groups were obviously improved, the cerebral infarction volumes and the ratios of cerebral infarctionvolumeswere significantly declined, cerebral infarction decrement was reduced. Zhuyutongmai (50~20 mg·kg-1) couldsignificantly prolong PT and increase SOD. The effects of Zhuyutongmai capsule on cerebral infarction were better than the positive controls. Conclusion:The preventive protections of Zhuyutongmai capsule on acute focal cerebral ischemia reperfusion injury in ratsare proved.
