[An isolated abdominal preparation in the rat].

A methodological approach proposed lies in the use of a complex abdominal preparation (an alimentary complex) of the gastrointestinal tract containing rat stomach, duodenum, small and large intestines and pancreas. The method is based on perfusion of the preparation vessels, namely of the vessels of the gastrointestinal tract or its parts both in situ and isolation of this alimentary complex. The alimentary complex is intended for solution of many problems of normal and pathological physiology, pharmacology and biology, permitting a deeper and broader insight into alimentary, transport, endocrine and regulatory functions of the gastrointestinal tract.
