Concentration of Circulating Advanced Glycation end Products of in the Model of Acute Renal insufficiency in Rats

Overview

Background.
Advanced glycation end products (AGEs) are formed from proteins and peptides by non-enzymatic glycation or glycoxidation. AGEs are formed slowly during aging, and they accumulate in circulation and tissues in diabetes and chronic renal failure. Kidney plays a key role in the disposal of AGEs. Aim of this study was to verify the hypothesis that, acute loss of renal function with enhanced oxidative and carbonyl stress should results in a rise of circulating AGEs levels.Method and Results. Acute renal failure (ARI) was induced in rats by bilateral nephrectomy (24-72 hours). The data on AGEs levels, oxidative status and antioxidative defense was compared to those of sham operated animals. 48 hours after the induction of ARI concentrations of AGEs, determined fluorimetrically or as carboxymethyllysine, rose 2-fold, and they correlated with concentrations of creatinine (r=0.938, p
