[The phenomenon of hyperproduction and in vivo shedding of excess epithelial layers of intestinal villi].

The native mucosa of enterobioptates of different animal species and men was examined with the use of binocular magnifier in combination with microscopic studies of serial sections of some intestinal villi isolated from mucous membrane. Areas with masses of fully or partially rejected excessive epithelial structures (long folds, plates, tubules) were revealed. The phenomenon under study is one of the sources of the epithelium in the mucous layer on the luminal surface of the small intestine.
