Abstract

This study was carried out to determine the effect of renal ischemia on renal function and excretion of amino acid in rabbit. The animal models of renal ischemia induced experimentally by clamping the renal artery for different lengths of time. These results were summarized as follows: 1. Ischemia for 30 or 60 min produced a polyuria which is accompanied by an increase in $Na^+$ excretion. Glomerular filtration rate (GFR) and p-aminohippurate plasma($C_{PAH}$) were not altered by 30 min of ischemia, indicating that transient ischemia results in a marked tubular dysfuction before a reduction in GFR or renal blood flow. 2. Reabsorption of glucose and amino acids such as alanine and lysine was markedly reduced after 30 min of ischemia, and the effect was more pronounced after 60 min of ischemia.
