针刺对实验性糖尿病大鼠视网膜病变的影响及其作用机理的研究

本研究对糖尿病大鼠的视网膜血管铺片进行了观察。与以往结论不同，本实验在３个月病程的糖尿病大鼠即发现其具有毛细血管曲张、管径不规则、微血管瘤和无细胞毛细血管等糖尿病性视网膜病变（ＤＲＰ）特征，病程至６个月时，各种病变进一步加重。针刺后观察，其微血管病变得到改善。有关机理研究的结果表明：针刺防治ＤＲＰ的作用机理是改善微循环、减轻血栓形成倾向、提高红细胞变形能力、降血糖等综合效应的结果。

Effect or Acupuncture on Retinopathy and Study on ItsMechanisms in Rats of Experimental Diabetes

In the present study. the smear of blood vessels of retina in rats of diabetes was observed.The results indicated that capillary varicose, irregular caliber. micrangium tumor,no-cellular capillary. and other characteristics of diabetic retinopathy(DRP) were found as early as 3 months after attack,and the various pathological changes deteriorated futher 6 months after attack, which were different from previous conclusion.Afer acupuncture, the pathological changes of micrangium were improved. It is suggested that prevention and treatment of DRP with acupuncture may be carried out by synthetical effects of improving microcirculation, reducing thrombosis, increasing transforman capicity of erythrocytes, decreasing blood sugar,etc.
