Abstract

The effect of sublethal toxicity of cadmium ions on the liver and gill of Cyprinuscarpio was investigated under laboratory conditions. After placement of Cyprinuscarpio in the vicinity Density (0/1LC50) Cadmium sampling days 1, 3, 7 and 14 of the second arc of gills and liver were, And the histopathological lesions were examined. After reviewing the intensity and timing complications, it seems that In the early hours of exposure to inflammatory damage caused And more destructive damage occurs. It is important that has liver the ability to Cyprinuscarpio Some inflammatory damage (Hypertrophy of hepatocytes and nuclear hypertrophy) to control the So that on the third day This damage can be minimized, But inflammatory damage in the gills became more intense with increasing time of exposure. Injury destructive in any mitigation process Was found in the liver and gills With increasing exposure time increases the severity of injuries.
