It is known that TCDD, one of the most toxic dioxin compounds, causes oxidative damage by forming free radical in human and animal tissues. In this study, the protective effect of PCA, an important phenolic compound, was examined in rat kidney and liver tissues with TCDD-induced toxicity. For this purpose, 28 Wistar Albino rats (3-4 months old and weighing 280-310 g) were used. Rats were randomly divided into 4 equal groups (control, TCDD, PCA and TCDD+PCA). TCDD and PCA were dissolved in corn oil at doses of 2 µg/kg and 100 mg/kg, respectively. Subsequently, the substances were administered to the rats by oral gavage for 45 days. The test results showed that in both kidney and liver tissues, TCDD increased the level of malondialdehyde (MDA) but inhibited the level of glutathione (GSH) and the activities of superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px). PCA administration was found to increase the enzyme activities and GSH levels, whereas it decreased the TCDD and MDA levels. In conclusion, it was observed that PCA decreased the TCDD-induced lipid peroxidation, increasing the antioxidant activity. Therefore, it might be suggested that PCA is a potential reducing agent for the toxicity caused by TCDD. |
