[Functional and structural myocardial changes in experimental glomerulonephritis].
Functional structural changes in the myocardium in different developmental phases of nephrotoxic glomerulonephritis were studied in rats. Electrocardiography, electron microscopy, and biochemical study of respiration, linked with oxidative phosphorylation, by polarography in the fraction of mitochondria isolated by differential centrifugation were employed. In experimental glomerulonephritis the ECG shifts were attended with diminished oxidative phosphorylation in the myocardial mitochondria, destructive changes in the cardiomyocytes (disorganization of mitochondria, myofibrils, endoplasmic reticulum), loosening and swelling of the basilar membranes, and changes and swelling in the capillaries and interstitium. The functional structural changes in the heart are reversible in character but persist for a longer period of time than the clinical manifestations of glomerulonephritis.
