Scanning and transmission electron microscopy (S.E.M. and T.E.M.) and resin histology have been used to investigate the effects on mouse small intestinal villi of heating at 43 degrees C for 20 minutes and of irradiation with 10 Gy X-rays. Damage after irradiation included conical villi and giant cells. Damage after heating included the production of conical and rudimentary villi and the stacking of enterocytes. Individual cells showed signs of abnormalities in their cell membranes, nuclei and cytoplasmic components. The differences in the response after irradiation and hyperthermia are linked to the fact that heating has a primary effect on villous structure, whereas irradiation mainly affects the proliferative pool of crypt cells.
