[Ultrastructure and function of cellular elements of the thymus during formation of antitubercular immunity].
Electron microscope and histochemical study of the thymus was carried out on growing guinea pigs under normal conditions and during the immune responses in BCG vaccination. During the postvaccinal period, particularly at periods of from 3 to 7 days, there was a change in the cell elements ultrastructure of the hemato-encephalic barrier. The greatest shifts were noted in the reticular and endothelial cells. The data obtained pointed to the intensification of the morpho-functional activity of the mentioned cell elements of the thymus during the formation of antituberculosis immunity.
