Morphological study of the effect of abdominal compression on acute intestinal radiation syndrome. II. Local irradiation with 30 Gy.

The radioprotective effect of abdominal compression introduced by Svoboda et al. on rats exposed to local irradiation of the abdomen with 30 Gy was studied using light microscopic and histochemical methods. Irradiation combined with abdominal compression does not lead to the development of typical radiation alterations of intestinal mucosa. The protected animals retained normal structure of intestinal and colon mucosa, and unchanged epithelium with typical enzymatic equipment. Local differences in protective effect may be due to various degree of ischemization of intestinal tract.
