36只兔分对照组和实验组。实验组施行了左肾动脉或左肾动、静脉同时结扎手术。术后动物生活正常,3～8个月后杀死。分别观察肾侧支循环的建立及肾的大体解剖、显微结构和组织化学变化等。1.结扎左肾血管后,因未能建立有效的侧支循环,致使左肾萎缩。右肾均呈现明显的代偿性肥大,其重量也明显增加。2.代偿肥大肾是由于原有肾单位的代偿肥大,以及其间结缔组织增生所造成的。3.代偿肥大肾与对照组相比,在 JGI、PAS、AIP 等方面均无显著差异。这可能提示代偿肥大肾至少在肾素分泌和重吸收机能等方面基本正常。
36 rabbits were divided into control group and experimental group. In the experimental group, left renal artery or left renal artery and vein were ligated simultaneously. After normal animal life, 3 to 8 months after killing. To observe the establishment of renal collateral circulation and renal gross anatomy, microstructure and histochemical changes. Left ligation of the left renal vascular, due to the failure to establish an effective collateral circulation, resulting in left atrophy. Right kidney showed significant compensatory hypertrophy, its weight is also significantly increased. 2 compensatory hypertrophy due to the original renal unit compensatory hypertrophy, as well as during the connective tissue hyperplasia caused. 3. Compensated hypertrophy kidney compared with the control group, JGI, PAS, AIP, etc. no significant difference. This may prompt compensatory hypertrophy at least in the renin secretion and reabsorption function and other aspects of the normal.
