Histological studies on the kidney of Marwari Sheep (Ovis aries)

Abstract

The microscopic studies of kidneys of 6 Marwari sheep showed that the thick fibrous capsule consisted of two layers. The outer layer of dense collagenous fibres with a few elastic fibres. Fibroblast and some smooth muscle cell were also present in outer layer. The inner layer consisted predominantly of reticular fibres with collagenous fibres and had a distinct thick smooth muscle layer. Interstitial tissue contained network reticular fibres which extended from the capsule to the apex of papilla. The juxtaglomerular structure and basement membranes were P.A.S. positive. The papillary duct lined with simple columnar epithelium which become transitional before opening into the papilla.
