[Ultrastructural analysis of the cortical substances of the adrenal glands of rats under conditions of bilateral subdiaphragmatic vagotomy].

Electron-microscopic study of zona fasciculata and zona reticularis of the adrenal cortex showed that 7 days after bilateral subphrenic vagotomy there occurred a diatation of the perinuclear space of adrenocorticocytes and endothelial cells; there was also a dilatation of the tubules in the smooth cytoplasmic reticulum, edema of the mitochondria, reduction of their cristae, and increase in the number and size of lipid drops. In 45 days there are encountered mitochondria with the beginning myelinization, lipid drops form accumulations, and electron-transparent vacuoles are revealed in them. The functional activity of adrenocorticocytes in zona fasciculata and zona reticularis of the adrenal cortex diminished in rats after vagotomy.
