The experimental myocardial damages were induced in Wistar rats by noradrenaline infusion (20ug/kg body wt/minute)for a period of 90 minutes daily for three consecutive days. The animals weresacrificed few minutes (acute phase), 7 days(subacute phase),and 30~90 days (chronic phase)afterinfusion. Specimens of myocardium were examined by histopathological, immunohistochemical and ultrastructural methods. Multiple focal necrosis, deficient of myoglobin in myocytes, myofibrillar fragmentation and dissolution were observed in the acute phase. The mdrphofogical feature simulated themyocardial infarctinn without coronary occlusion. Focal myocardial atrophy, scar f0rmation of myocardium, proliferation of fibroblasts and infiltraiton of the neo-colleagenous fibrils in necrotic myocytes were observed in the subacute and chronic phase. This feacture simulated the early cardiomyopathy.

大鼠尾静脉滴去甲肾上腺素(20μg/kg/min)后,分别于即刻、7天、30~90天杀死取材,用病理组织学、肌红蛋白免疫组化染色及透射电镜观察心肌损伤。结果:早期可见心肌多灶性坏死、肌红蛋白缺染、肌原纤维断裂溶解,似冠状动脉无阻塞性心肌梗死;中后期可见心肌灶性萎缩及疤痕形成、成纤维细胞增生活跃、新生胶元原纤维伸入坏死心肌内,类似早期心肌病图象。

Objective:To discover nicotinamide's action on serum endothelin and protection in experimental myocardical damage of rats.Method:Randomly divided 60 wister rats into 3 groups:Control group,myocardial damage model group and nicotinamide therapy group. Changes of endothelin (ET),creatine phosphokinase (CPK) and lactic dehydrogenase (LDH) were tested and the grade of myocardial damage were observed.Result:Contrasting model group with control group,the levels of ET,CPK and LDH were high (P< 0.05 ),myocardial...

Changes of endothelin (ET),creatine phosphokinase (CPK) and lactic dehydrogenase (LDH) were tested and the grade of myocardial damage were observed.Result:Contrasting model group with control group,the levels of ET,CPK and LDH were high (P< 0.05 ),myocardial damage was heavy.The levels of ET,CPK and LDH were lower in therapy group than in model group,the myocardial damage was light.The difference was little between therapy group with control group (P> 0.05 ).Couclusion:Nicotinamide has protective effect on experimental myocardial damage of rats.

目的 :探讨烟酰胺对大鼠实验性心肌损伤血浆内皮素 ( ET)影响及心肌保护作用。方法 :用 Wistar大鼠 60只 ,随机分为心肌损伤模型组、烟酰胺治疗组和对照组 ,每组 2 0只。测定血中ET、肌酸磷酸激酶 ( CPK)、乳酸脱氢酶 ( L DH)变化并观察心肌组织学损害程度。结果 :模型组与对照组比较血中 ET、CPK、LDH明显增高 ( P <0 .0 5 ) ,心肌组织学损害程度较重。治疗组与模型组比较血中 ET、CPK、L DH显著下降 ( P<0 .0 5 ) ,组织学受损程度轻、例数少。治疗组与对照组比较血中 ET、CPK、L DH无显著性差异 ( P >0 .0 5 )。结论 :烟酰胺对大鼠实验性心肌损伤有明显的保护治疗作用。
