There are considerably fewer works dealing with the reaction of stromal elements of the mucosa of the small intestine in the presence of radiation pathology than with injury to the epithelial layer. These works deal primarily with the morphophysiology of the vascular component. Data on changes in interstitial stroma cells, particularly in the first postradiation hours, are given in isolated works and they are indicative of high radiosensitivity of many stromal elements. Our objective in this article was to make a comprehensive analysis of ultrastructural changes in the mucosal stroma of the small intestine as related to different doses of radiation, and to compare our results to the reaction of proliferative cryptal cells of the same laboratory animals.
