Abstract

Background and Objective: 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. Methods: 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. Results: 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). Conclusion: The simultaneous use of endurance exercise training and curcumin due to increased IgA activity has beneficial effects against lead poisoning.

Abstract

Background and Objective: The kidney has a key role in homeostatic regulation. Vascular endothelial growth factor (VEGF) is essential regulator of stimulatory and inhibitory processes for neonatal, post-natal endothelial cell differentiation. This study was done to determine the effect of maternal swimming during pregnancy on VEGF level of kidney in rat pups. Methods: In this experimental study, sixteen Wistar rat dams were allocated into interventional swimming and control groups. In the first day of pregnancy, in interventional group, swimming was performed for 30 minutes a day and 5 minutes every day was added until the time of training gradually reached to one hour per workout. Dams swimming endurance training were performed in 5 days per week for three weeks. Pups’ kidneys were removed two days after birth and kindney tissue VEGF level was determined using ELISA method. Results: Kidney tissue VEGF level in interventional swimming group (133.13 pg/ml) was significantly increased in compared to controls (48.19 pg/ml) (P<0.05). Conclusion: Swimming endurance training increases the pups’ kidney VEGF level.
