A Histological and Histochemical study of small intestine in adult stage of cats.

Abstract

This study was performed to detect histological & histochemical facts of the bowel in adult cats.was approved on six mature cats the body masses it between 3 to 3.5 Kg, which occur in College of Veterinary Medicine, University of Baghdad. Killing euthanized by injection of an overdose of sodium pentobarbital intra-cardiac. Tissue sections were treated, sectioned and exposed to specific dyes to detected histological details.small intestine of adult cats is lined by simple columnar epithelium with goblet cells. The general architecture was like to other mammals with little individualities: the shape of the villi different from leaf-similar in the duodenum ,pointed in jejunum &leaf-formed in the ileum due to the type nutrition, the Brunner’s gland was current in the initial portion and caudal part duodenum and initial part of the jejunum act to neutralize the acidity of the food coming from the stomach with foods.The paneth cells have few numbers with rather epithelial cells in duodenum. Peyer's spot was current at the termination of jejunum and ileum. Goblet cells were able to secrete a high amount of slimy mucous into the lumen of the bowel ,.Carbohydrate profile small intestine shown the found of non-sulfated acidic mucin in the crypts and intestinal glands while the a neutral & sulfated acidic mucins found in the villi & superficial epithelium.
