Abstract
At this study, kidneys of 10 normal fishes have been studied macroscopic and microscopically. The kidneys were collected by autopsy and tissue samples were sectioned by routine paraffin embedding and stained by H&E and PAS. Macroscopic observation showed that the kidney in Barbus grypus situated in the ventral region of vertebral column. The kidney could be divided into; head, body and tail portions according to their relative position. Microscopic studies showed that the kidneys consisted of excretory portion and hematopoietic-lymphoid tissues. Anterior portion of kidney (head) had more Hematopoietic-lymphoid tissues than the posterior portion (body and tail). Hematopoietic-lymphoid tissue consisted of cells which were found in different stages of development to blood cells. Excretory portion of kidney parenchyma consisted of renal corpuscle and urinary tubules. In microscopic section of glomerulus, endothelial and mesangial cells and nucleated red blood cells were seen. The number of renal corpuscles in the posterior portion of kidney was more than the anterior portion significantly, while there was no significant difference between the average diameter of renal corpuscles in the head, body and tail portions of kidney. Urinary tubules consisted of neck segment, proximal tubule (first and second portion), intermediate segment and distal segment. The collecting ducts were situated after the distal segments. No significant difference was observed in the measured parameters between the males and females fishes in this study. Based on the results of this study, the kidney of Barbus grypus is very similar to other species of the family Cyprinidae, histologically and anatomically.
