Bisphenol A (BPA), commonly found in plastic packaging and cans, can induce oxidative stress. This study was aimed to prove that oral BPA could decrease superoxide dismutase (SOD) and increase F2-isoprostan levels in male Sprague Dawley rats. This was an experimental study using randomized pretest-posttest control group design. There were 14 rats (Rattus norvegicus), male, Sprague Dawley strain, 8-10 weeks old, as subjects. Rats were divided into two groups with 7 rats each. The control group (P0) was treated with placebo for 21 days and the treatment group (P1) was treated with oral BPA dose of 400mg/kg for 21 days. Before and after treatment for 21 days, blood was drained through the canthus medial sinus orbital and urine was collected as pretest and posttest data. SOD and F2-isoprostan levels were then examined by using ELISA. The results showed that before treatment (pretest), the mean SOD level in P0 group was 42.51±3.127 U/mL and in P1 group was 41.87±2.477 U/mL (P > 0.05). The mean F2isoprostane level in P0 group was 3.18±0.599 ng/ml and in P1 group was 3.22±0.489 ng/ml (P > 0.05). However, after treatment for 21 days (posttest), the mean level of SOD in P0 group was 43.52±3.472 U/mL and in P1 group was 31.84±2.563 U/mL (P <0.01). The mean level of F2isoprostane in P0 group was 2.94±0.500 ng/ml and in P1 group was 4.47±0.241 ng/ml (P < 0.01). The analysis of the treatment effect showed significant decreased level of SOD and increased level of F2-isoprostane in P1 group (P < 0.01). Conclusion: Oral bisphenol A could decrease superoxide dismutase (SOD) and increase F2-isoprostan levels in male Sprague dawley rats.
