摘要: 目的: 探讨异丙肾上腺素(isoprote renol, Iso)对 大鼠,心肌纤维化和相关细胞因子的影响。方法: 20只SD大鼠随机分成正常对照组(空白组)、异丙肾上腺素组(Iso组),每组10只。Iso组经皮下注射Iso 后,对两组行组织学观察心功能、胶原容积分数(CVF)、胶原蛋白含量和血浆中血管紧张素II(An­gll)、一氧化氮(NO)浓度的测定。结果: 与空白组相 比,Iso组心肌细胞间有大量胶原增生, 心功能有所降低,CVF、胶原蛋白含量和Angil含量增加,NO含量降低,最大上升速率(+ dp/dtmax)和心室收缩压(LVSP)未见明显改变。结论: Iso能促进大鼠,心肌纤维化和相关细胞因子浓度的变化。

Abstract: AIM: To study the effects of isoproterenol(Iso on cardiac fibrosis and related cytokines in rats.METHODS: 20 SD rats were divided into control and Isgroup in random, with 10 rats each group. After injectedIso, cardiac histology was observed and cardiac function collagen volume fraction (CVF), content of collagen protein and the concentrations of Angiotensin II (Angll) andnitrogen monoxide (NO were measured in the two groups.RESULTS: Compared with control group, mi) scopic examination Showed that fibrosis Increased In Iso group. Iso did decrease cardiac function and NO levelsand increase CVF, content of collagen protein and Anglllevels. Left ventricular pressure maximal rate of rise (+dp/dtmax) and left ventricular systolic pressure (LVSP) were not significantly different from that of control group.CONCLUSIONS: Iso can induce myocardial fibrosis andchange levels of related cytokines in rats.
