In experiments on laboratory non-linear white rats with sublimate nephropathy (mercury dichloride, 5 mg/ kg subcutaneously) and hypoxic histohemic nephropathy (HHHN; sodium nitrite, 50 mg/kg subcutaneously and 2,4-dinitrophenol, 3 mg/kg intraperitoneally) the effect of ATP-sensitive potassium (KATP) channels activation induced by flocalin (5 mg/kg intragastric administration, for 7 days) on kidney protein excretion was studied. Flocalin use causes a decrease in standardized by glomerular filtration rate proteinuria: by 4.5 times and 1.2 times in rats with both acute and chronic sublimate nephropathy; and by 1.6 and 2.1 times, simultaneously, under the conditions of hypoxic injury of nephrocytes. Antiproteinuric effect of flocalin during both acute and chronic periods of nephropathy was accompanied by an increase in enzymatic activity of alkaline phosphatase (by 18.1 % and 49.9 % – in rats with sublimate nephropathy; by 18.1 % and 4 % – in rats with HHHN) and succinate dehydrogenase (by 36.3 % and 56. 7% in rats with sublimate nephropathy; reaches control level in rats with acute НHHN and increases by 71.2 % in rats with chronic НHHN) in kidney cortex. Conclusion was made about the nephroprotective effect of KATP-channels activation induced by flocalin predominantly in the proximal part of nephrons.
