Abstract

The protective effects of a herbal compound Liv52 were studied against mercuric chloride (0.1 mg/l) induced histochemical and histological changes in gill of a fresh water catfish Heteropneustes fossils (Bloch). Heavy metal accumulation was seen in the secondary gill filaments in mercury exposed fish, while moderate Hg deposition was seen in the Hg + Liv52 treated group. The effective recovery was seen in the Liv52 fed fishes as against the normal recovery. Similarly, the structural damages such as degenerated lamellar epithelium, curved and exposed pillar cells in gill was lesser in the Hg + Liv52, as well as in the recovery with drug. This suggests preventive and curative effect of herbal compound against mercury intoxication in gill of H. fossilis.
