目的：探讨长时间低强度游泳运动对心血管系统CGRPmRNA表达的影响。方法：雄性SD大鼠随机分为三组（n=8）：安静对照组（CR）、运动力竭组（ER）和运动训练组（rrR）。RT-PCR测定心尖肌组织和主动脉弓部血管CGRPmRNA的表达水平。结果：①一次急性有氧力竭游泳运动对大鼠心脏和主动脉CGRPmRNA表达无显著影响。②长时间进行低强度有氧游泳训练能引起心脏CGRPrnRNA表达显著上调。结论：长期低强度的有氧运动训练后心脏在分子水平上有良好适应；而长时期进行低强度有氧游泳训练对主动脉CGRPmRNA表达无显著影响。

AIM: Rats cardiovascular expression of CGRPmRNA surveyed after an eight-week swimming training, and molecular mechanism of exercise-induced adaptation were studied. METHODS: 24 purebred male SD rats were divided randomly into three groups (n = 8): control (CR), exhaust (ER), train (TR). After swimming training left ventricular muscle and main artery arch were extracted, we inspected the expression of CGRPmRNA by RT-PCR. RESULTS: (1) Comparing with the control group, once exhausting exercise had no significant effect on cardiovascular expression of CGRPmRNA. (2) Comparing with the control group...
