Structural and cytochemical changes in the small intestine wall at cotact impact of the obturator of polyurethane and teflon
The experimental studies have been done to determine the influence of the elastic obturators made of foamed polyurethane and teflon on the structural and cytochemical changes in the small intestine wall. It was determined that the present elastic obturators do not cause marked changes in the intestinal wall during the contact impact on the intestine for 24 hours within 14 days and the revealed deflections in enzyme activity of the epithelial cell villi are feebly marked and can not influence villi functional condition.
