[A morphologic analysis of denuding of the villi in the intestinal form of acute radiation sickness].
Light and electron microscopy were applied to the study in sexually mature rats and mice of the areas of the duodenum, jejunum and the ileum 3-4 days after the irradiation in doses of 1000, 1500, 7000 and 15 000 R. Paraffine mucosal sections of the small intestine showed denuding of the stroma of individual villi. However, a study of the thin and semithin epon sections by light microscopy and of the ultrathin ones--by electron microscopy showed the villi to be always covered with enterocytes, whose cytoplasm was overloaded with lipid droplets and almost structureless. Thus, during the enteric form of acute radiation sickness there was no vital denuding of the villi, and the presence of such on paraffine sections served as the result of inadequate treatment of the material.
