Comparative Histochemical and Histoenzymological Studies on the Kidney of Domestic Animals

Abstract

The histochemical and histoenzymological aspects of kidney were studied in buffalo, sheep, pig and dog. The glomeruli, parietal and visceral layers of Bowman’s capsule exhibited intense positive activity for PAS and moderate to intense activity for PAS-AB in buffalo, sheep, pig and dog. The basement membranes around the renal corpuscles and tubules of cortex and medulla showed intense activity for PAS in buffalo, sheep and pig and moderate activity in dog. The cortex showed intense alkaline phosphatase and acid phosphatase activity and fat deposition was observed in the tubules of cortical labyrinth in buffalo, sheep, pig and dog. The glomeruli of kidney showed more protein activity in buffalo and less activity in sheep, pig and dog. The strong activity for renin was observed at the vascular pole surrounding the afferent and efferent arterioles close to the macula densa in all domestic animals.
