[A clinico-morphologico-functional study of the kidneys in glomerulonephritis]

The article deals with the results of a clinico-functional-morphological study of the kidneys in glomerulonephritis (50 observations) which was carried out with the use of the method of puncture biopsy of the kidneys. It was shown that clinical forms of glomerulonephritis, accompanied with hematuria, were characterized by the absence of fixation of immune complexes in the basal membrane of the glomeruli. According to the electron microscopy data, this corresponds to the dissappearance of deposits from the subendothelial parts of the basal membrane. The extramembranous glomerulonephritis, revealed with the help of electron microscopy technique, was characterized by the nephrotic syndrome. An increased tension of immunological processes in the glomeruli was accompanied by a more grave clinical course of glomerulonephritis, by impairment of not only glomerulous but tubular functions as well. A greater dicrease in the function of osmotic concentration of the urine in fibroplastic types of glomerulonephritis, as compared with non-firboplastic ones, was apparently connected not only with lesiones of tubules but rather with more expressed sclerotic changes in the interstitial tissue of the kidney.
