Abstract
This study aims to determine the potential of melanomacrophage centers (MMCs) as a bioindicators of environment polluted with mercury chloride. This study used the carp fish that were kept in an environment that contained mercury chloride with a concentration of 0.01, 0.05 and 0.1 ppm for 21 days. The rate of accumulation of macrophages in the tissue of kidney, spleen and liver were measured by the activity of N-acetylglucosaminidase. The results showed that the MMCs in the spleen and liver tissue of the carp fish potential as the bio-indicators of polluted environment ≥0.1 ppm of mercury chloride. The increased in accumulation of macrophages found in the kidney tissue of carp fish exposed to mercury chloride concentration of 0.01, 0.05 and 0.1 ppm, although no significant difference with control (0 ppm). The suppressive effect of the accumulation of immune response showed at the carp fish liver tissue macrophages which were exposed to mercury chloride lower than carp fish that were not exposed.
