Effects of Chromium on Histological Alterations of Gill, Liver and Kidney of Fresh Water Teleost, Cyprinus carpio (L.)

Authors : K. Parvathi, P. Sivakumar and C. Sarasu

Abstract: Lethal effects of chromium on the histological alterations of fresh water teleost, Cyprinus carpio were studied. The fish exposed to lethal concentrations of chromium for 96 h showed clubbing of the secondary lamella in the ends, fusion of adjacent secondary lamella, epithelial lifting, necrosis and curling of secondary lamella. Hepatic cirrhosis, fatty changes, degeneration of parenchyma cells results in atrophy, tissue ischemic and extensive necrosis of liver cells were recorded. Hypertrophy of epithelial cells, contraction of glomerulus, increase of space inside the grouping of tubules, distortion of architecture, glomerular edema were observed when the fish exposed to lethal concentrations of chromium. Bowman’s capsule, atrophy and dispersed interrenal cells with pyknosis of some nuclei were observed in kidney of C. carpio exposed to lethal concentrations of chromium.
