title: Augmentation of cholinesterases and ATPase activities in the cerebellum and pons-medulla oblongata, by a combination of antioxidants (resveratrol, ascorbic acid, alpha-lipoic acid and vitamin E), in acutely lindane intoxicated mice.
abstract: In the present investigation neurotoxic effects of lindane and the protective potential of a combination of antioxidants against lindane-induced toxicity were evaluated in Swiss mice. The investigation was carried out on acetylcholinesterase (AChE), butyrylcholinesterase (BChE) and adenosine triphosphatase (ATPase) activities of the cerebellum and pons-medulla oblongata. Healthy mice, 7-8 weeks old were administered acute dose of lindane (40 mg/kg b.w.), antioxidants, both lindane and antioxidants, and vehicle in four separate groups, subcutaneously. Resveratrol (Res), ascorbic acid (C), alpha-lipoic acid (ALA) and vitamin E (E) were used in the combination for neuroprotection at the concentration of 5 mg/kg b.w., 50 mg/kg b.w., 20 mg/kg b.w. and 50 mg/kg b.w. respectively. Enzymatic activities were used as biochemical marker for manifestation of lindane-induced acute toxicity. Protective effects of antioxidants were also evaluated using the same parameters. Treatment of lindane to normal control animals resulted in a significant decrease in AChE, BChE and ATPase levels in crude homogenates of cerebellum and pons-medulla. Antioxidants treatment significantly increased the levels of enzymes. Critical difference (CD) of AChE, BChE and ATPase levels in various groups was found significant at 1% in cerebellum and pons-medulla both (i.e. P<0.01).
