胆胰康对慢性胰腺炎大鼠血清超氧化物歧化酶活性、羟脯氨酸含量及胰腺病理的影响

目的:通过观察中药胆胰康(DYK)对慢性胰腺炎(CP)大鼠血清超氧化物歧化酶(SOD)活性、羟脯氨酸(HYP)含量的影响及胰腺病理改变,进而探讨该方药治疗CP的机理。方法:从70只SD大鼠(雌雄各半)中随机抽取20只(雌雄各半)作为正常组大鼠,其余50只大鼠采取腹腔注射L-精氨酸(L-Arg)的方法制造慢性胰腺炎动物模型。3周后抽取正常大鼠10只(雌雄各半)、模型大鼠10只(雌雄各半),分别检测血清SOD活性及HYP含量,镜下观察胰腺组织改变。验证造模成功后,将剩余的40只模型大鼠随机分为4组:模型组(b)、小柴胡汤丸组(c)、胆胰康低剂量组(d)、胆胰康高剂量组(e)。剩余的10只正常大鼠作为空白组(a)。从第4周起给药治疗,治疗4周后,处死全部大鼠,提取血清检测SOD活性及HYP含量,观察胰腺组织病理改变。进行实验数据统计。结果:b血清SOD活性明显低于a(P0.01),HYP含量高于a(P0.01),c、d、e血清SOD活性均明显高于b(P0.01),HYP含量明显低于b(P0.05)。所有治疗组胰腺组织均有不同程度病理改变。结论:采取腹腔注射L-Arg的方法能够成功地复制大鼠CP模型,DYK能够有效地提高CP大鼠血清SOD活性,降低其血清HYP含量,能够有效地对抗CP形成过程中的胰腺组织损伤,从而对CP具有显著的防治作用。

Effect of DanYiKang on Serum Superoxide Dismutase Activityhydroxyproline Content and Pancreatic Pathology of Chronic Pancreatitis Rats

Objective:To explore the mechanism of DanYiKang (DYK)to treat chronic pancreatitis (CP) by observing the serum superoxide dismutase (SOD)activity,hydroxyproline (HYP)content and pancreatic pathology of chronic pancreatitis rats.Method:70 Sprague-Dawley (SD) rats were randomly drew-out 20 rats as normal control group,50 rats were intraperitoneally injected L-Arg to make CP rat model.3 weeks later,normal rats and model rats were extracted 10 respectively,whose serum SOD activity and HYP content were tested,an...
