Methods of selection, preparation and evaluation of the viability of small-intestinal fragments suitable for transplantation

In the experiment performed on cats, using histological, histochemical and impregnative techniques it has been stated that choose of the small intestine area, suitable for transplantation should be based on counting straight vessels ramified in it. In order to ensure viability of the small intestine fragment the method of its preliminary treatment is recommended, based on training blood vessels. For estimating viability of the transplant it is possible to ascertain SDG activity in neurons of the intramural nervous ganglia and estimate amount of secreting gobletlike cells in mucous membrane of the small intestine loop.
