关键词: 参附注射液;脑缺血;治疗时间窗摘 要:目的 探讨参附注射液对局灶性脑缺血性损伤的治疗时间窗. 方法 80只雄性SD大鼠,随机分为8组(每组n=10):对照组,即单纯缺血再灌注组;参附注射液治疗A~G组,分别于缺血再灌注后0,0.5,1.0,1.5,2.0,4.0和6.0h经腹腔注射参附注射液,剂量为10mL kg-1 .用右侧颈内动脉线栓法致大脑中动脉阻闭120min,拔出尼龙线即刻为再灌注时间.观察再灌注后24h时神经功能损害改变并评分,24h时处死动物,取大脑行TTC染色以测量脑梗死容积. 结果 24h时神经功能损害评分,A~F组分别为:0.5±0.3,0.5±0.4,0.6±0.5,0.8±0.4,0.8±0.3和0.9±0.3,明显低于对照组(2.1±0.8)及G组(1.5±0.7)(P<0.05).脑梗死容积A~F组分别为(46.4±26.1),(60.2±25.8),(67.2±36.7),(76.0±39.7),(94.1±34.9)和(98.4±35.3)mm3 ;均明显小于对照组(182.6±39.6)mm3 及G组(139.1±42.8)mm
3 (P<0.05),A~F组间24h时神经功能损害评分和梗死容积无差别(P>0.05). 结论 参附注射液对局灶性脑缺血再灌注损伤的最佳治疗时机在缺血后4h以内.
