    Abstract:
    Reactive oxygen species (ROS) may be involved in the pathogenesis of serum induced by dichlorvos. Therefore, the rationale of present research was to evaluate the ameliorative efficacy of bacoside A and bromelain on oxidative stress biomarkers in serum of dichlorvos intoxicated mice. Also the level of serum antioxidants viz. catalase (CAT), superoxide dismutase (SOD), glutathione peroxidase (GPx) and reduced glutathione (GSH) were measured. For experiments, mice were allocated into six groups. First group received saline as a vehicle; second group was administered with dichlorvos (40 mg/kg b.w.); third group was administered with bromelain (70 mg/kg b.w.), fourth group received dose of bacoside A (5 mg/kg b.w.), fifth group was given concomitant exposure of bacoside A and bromelain both and mice of sixth group were exposed to bacoside A, bromelain and dichlorvos for 21 days consecutively. Oxidative stress biomarkers thiobarbituric acid reactive substances (TBARS) and protein carbonyl content (PCC) and antioxidants (CAT, SOD, GPx and GSH) level of serum was determined to elucidate the protective potential of bacoside A and bromelain against dichlorvos intoxication. Significantly increased TBARS and PCC level in second group suggests that dichlorvos enhances the production of free radicals in serum of mice (p < 0.05). Antioxidants treatment significantly decreased the levels of TBARS and PCC (p < 0.05). Dichlorvos administration causes a significant reduction in the level of CAT, SOD, GPx and GSH (p < 0.05) which was restored significantly by co-administration of bromelain and bacoside A in dichlorvos exposed mice (p < 0.05). The bacoside A and bromelain are attributed with antioxidant properties. Finding of research conclude that concomitant exposure of bacoside A and bromelain was much effective in combating oxidative stress induced by dichlorvos.
