Morphology of rat small intestine in response to heat stress. (I) Photomicrographs of hematoxylin and eosin-stained sections of rat small intestine after 3 days of heat treatment. Upper panels show small intestine from control rats, lower panels show small intestine from heat-stressed rats. Thermal injury to the intestinal villi is apparent, with hyperemia desquamation at the tips of the intestinal villi. (II) Morphology of rat small intestine at higher magnification. Heat stress resulted in profound damage to the epithelium of the small intestine. Sloughing of epithelium off the basement membrane at the villus tips and even exposing of the lamina propria are more obvious at higher magnification. Abnormal microstructures are indicated by arrows
