Abstract:

研究了姜辣素对60Coγ射线损伤小鼠造血和抗氧化功能的治疗作用。18只雌性健康昆明小鼠被随机分为3组,每组6只,分别为对照组、照射组、照射给药组。对照组不照射,连续灌胃5d蒸馏水;照射组和照射给药组分别用3Gy60Coγ射线进行照射,并分别在照射后30min内灌胃蒸馏水和姜辣素,连续5d。末次灌胃后48h内测定所有小鼠血液中白细胞(WBC)和红细胞(RBC)数量、脏器指数、肝脏超氧化物歧化酶(SOD)活性、总抗氧化能力(T-AOC)、丙二醛(MDA)含量及骨髓嗜多染红细胞微核(MN)数目。与对照组相比,照射组脾脏指数、WBC极显著降低(P<0.01),肝脏MDA含量、骨髓MN数目极显著升高(P<0.01);与照射组相比,照射给药组脾脏指数、T-AOC、SOD活性极显著升高(P<0.01),肝脏指数、WBC、RBC含量也有所升高,MDA含量、MN数目极显著降低(P<0.01)。结果表明,姜辣素对60Coγ射线照射造成的小鼠造血、抗氧化功能损伤具有治疗作用。
