EXPERIMENTAL STUDIES ON THE RENAL VESSELS LIGATION IN RABBITS / 解剖学报

ABSTRACT

36 rabbits were divided into control and experimental groups.In the experimen-tal group,the left renal artery was ligated or the left renal artery and vein wereligated simultaneously.All the animals were alive.After 3—8 months of the opera-tion,the rabbits were killed.The establishment of collateral circulation and theanatomical,histological and histochemical changes of the kidny were observed.The resultsobtained were as follows1.Ligation of the left renal vessels causes atrophy of theleft kidney on account of the failure of collateral circulation establishment.Theright kidney of the experimental group showed obviously compensatory hypertrophy.The weight of the compensatory hypertrophied kidneys obviously increased.2.Thecompensatory hypertrophic growth of kidneys is due to the hypertrophy of existingn(?)phrons and the hyperplasia connective tissue.3.comparison of the controls,inthe JGI,PAS and AlP reactions with the compensatory hypertrophied kidneys,there were no striking differences.The results suggest that the compensatory hyper-trophied kidneys were normal at least on the renin secretion and reabsorption func-tion.
