Popis: | The influence of surgical sympathetic denervation on the morphological parameters of the effector part of immune protection in the rat small intestine was investigated at different time periods after the operation. The disturbances in sympathetic innervation leads to the activation of the immune system. The activation is expressed in an increase in the amount of intraepithelial lymphocytes in intestinal villi and the amount of lymphocytes and plasmocytes in mucous tunica propria. The morphological changes observed correlate with a decrease in intestinal epithelial thickness. This may be caused by increased stimulation of the intestinal immune protection by antigens contained in the chyme . |
