Histological alterations in liver and intestine of teleost Sarotherodon mossambicus in response to mercury toxicity.
Effects of lethal (1.5 ppm) and sublethal (0.1 ppm) concentrations of HgCl2 on liver and intestine tissues of Sarotherodon mossambicus were studied by routine histological techniques. Engorged blood sinusoid, vacuolation, rupture, granular degeneration of hepatocytes, edema, focal necrosis, and proliferation of fibroblasts were the alterations observed in liver. Rupture of the tips of the villi, proliferation of villi, increase in goblet cell population, and focal necrosis of villi were the characteristic changes in intestine.
