title: [Lipid peroxidation and Ca-dependent ATPase activity in the microsomal fraction of renal tissue in patients with nephrolithiasis and chronic pyelonephritis].
abstract: The author has estimated levels of malonic dialdehyde (MDA) indicative of activity of membrane phospholipid peroxidation activity, basal and true (in incubation in the culture containing glomeruloform antibiotic alameticin) Ca-ATPase activity in microsomal fraction isolated from cortical tissue of functioning kidneys obtained intraoperatively from 26 patients. 12 samples of cortical tissue obtained from uninvolved parts of the kidneys affected with carcinoma served as control. 14 samples were obtained from the tissue of functioning kidneys affected with nephrolithiasis and active chronic pyelonephritis. The investigations show elevated MDA levels, enhanced basal in reduced true Ca-ATPase activity of microsomes from the kidneys of patients with nephrolithiasis and active chronic pyelonephritis compared to control. It is suggested that high basal against low true Ca-ATPase activity of renal microsomes may be explained by increased permeability of renal membranes for Ca2+ under activation of lipid peroxidation in active chronic pyelonephritis and nephrolithiasis.
