[Ultrastructure of the duodenal mucosa in rats under stress].
Electron microscopy study of the duodenal mucosa of rats after a 24-hour restrain stress was conducted in a special apparatus. Moderate changes of enterocytes chiefly consisting of focal destruction of mitochondrial cristae and increase in the number of lysosomes were revealed. These results correlate with the previously published data on histochemical study of the same objects. The changes of the  goblet cells and of the blood vessels are described.
