Abstract
Bisphenol A is a well-known toxin whose effects on reproductive toxicities. However, recent years, it has also been known BPA causes oxidative stress. Oxidative stress is one of the factors causing organ damage, this study aims to prove the effect of oral bisphenol A administration on malondialdehyde levels and apoptotic index in rat liver. This study used a posttest only control group design. Subjects were 14 male Sprague Dawley rats, male, aged 8-10 weeks, body weight 180 grams, and healthy. The control group (P0), 7 rats, were given a placebo of 1 ml aquadest for 21 days- while the treatment group (P1), 7 rats, were given 400 mg/kgBW of BPA for 21 days. The results showed that the P1 group had higher hepatic MDA levels (3,33- 0,27 nmol/mg.prot) and significantly different (p<0,001) than the P0 group (2,67- 0,14 nmol/mg.prot). In addition, the P1 group had a higher apoptotic index (11,21- 2,26%) and significantly different (p<0,001) than the P0 group (2,19- 0,97%). Based on these results, it can be concluded that oral administration of bisphenol A increases malondialdehyde and apoptotic index in the liver of male Sprague dawley rats.
