临床及流行病学资料表明:糖尿病患者冠脉性心脏病的发生率较高。人类冠脉循环和动物实验研究也证实糖尿病可使冠脉血流量减少。作者研究了心脏活动增加时,糖尿病对冠脉血流量的影响。实验选用生物饲养的原发性糖尿病大鼠和健康对照大鼠。处死后取出心脏,按Langerdoff法进行冠脉 Clinical and epidemiological data show that: the incidence of coronary heart disease in diabetic patients is higher. Human coronary circulation and animal studies have also confirmed that diabetes can reduce coronary blood flow. The authors studied the effects of diabetes on coronary blood flow when heart activity was increased. Experimental selection of biologically-fed primary diabetic rats and healthy control rats. Remove the heart after sacrifice, according to Langerdoff method of coronary artery
