title: [Electron-microscopic and autoradiographic study of giant cells of foreign bodies in the focus of aseptic inflammation].
abstract: Ultrastructure of sinuous proximal and straight distal tubules, as well as collecting tubules of the cortical layer in the rat kidney fixed with perfusion has been studied with electron microscopic morphometry 7--8 weeks after contralateral nephrectomy. The volume of mitochondria, the area of their crists, the area of the membranes in intracellular labyrinth and other morphometrical parameters have been calculated. Relative volume of mitochondria in the nephron areas studied does not change, while in the collecting tubules it is elevated. The area of crists in mitochondria and "coefficient of morphological organization level" of these organells in the proximal tubules are increased, in the distal do not change, in the collecting tubules increase again. Subcellular changes described are discussed mainly in terms of enhancement of concentrating function of the compensatory-hypertrophic kidney.
