ABSTRACT
Lead as an environmental pollutant can damage the immune system. This study was done to determine the effect of moderate-intensity exercise and Curcumin supplement on serum level of immunoglobulin A in rats exposed to lead acetate. In this experimental study, 46 male rats were allocated into six groups including; Control [C], vehicle [V], lead [L], lead and exercise [LE], lead and curcumin [LC], Lead+exercise+curcumin [LEC]. Animals in training groups ran on treadmill for 8 weeks [25- 64 minutes per daily, 15-22 meter/minute and 0% grade]. Animals in Lead, LE, LC and LEC groups were received lead acetate [20 mg/kg/bw] and vehicle animals were received ethyl oleat [30 mg/kg/bw] Intraperitoneally for 3 days per week for 8 weeks. Rats in curcumin and LEC groups were received Curcumin [30mg/kg/bw], for 3 day per week for 8 weeks. IgA level were measured by single radial immuno diffusion method. Lead acetate significantly increased MDA levels at P<0.05 in animals. IgA level was 0.2, 0.41 and 0.47 mg/dL in Lead, LE and LEC groups [P<0.05]. The simultaneous use of endurance exercise training and curcumin due to increased IgA activity has beneficial effects against lead poisoning
