Histophysiologic aspects of the remnant intestine of rats subjected to partial resection of the small intestine

Abstract

The effect of small bowel resection on the morphology, mucous secretion and alkaline phosphatase activity of the remnant intestine was studied five months after surgical operation.Distal small bowel resection produced hyperplasia and infiltration of lymphocytes.The intestinal neutral and acid mucosubstances, and the alkaline phosphatase activity were increased in resected animals, whilst the sulphomucins content of goblet cells was unaltered.The serum alkaline phosphatase activity two and five months after resection was also increased.
