2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) induces hepatic damage. Propolis exhibits antioxidant properties and several studies suggest that supplementations with antioxidants can influence hepatotoxicity. Therefore, the aim of the current study was to explore the effectiveness of propolis in alleviating the toxicity of TCDD in the liver of rats. Animals were divided into six groups, namely, TCDD (0.75 and 8 mu g/kgbody weight (bw)), propolis (50mg/kgbw), TCDD (0.75 and 8 mu g) plus propolis (50mg/kg bw), and control, respectively. Rats were intraperitoneally administered with their respective doses daily for 21 days. In rats that received a high dose of TCDD, the antioxidant enzymes were significantly decreased and the serious pathological findings were established. Also, the rate of hepatocyte micronucleus (HMN) was increased after treating with TCDD. The reactions of enzymes in control and low-dose group were weak. The frequencies of HMN and liver histology were similar to both the groups. The presence of propolis with TCDD alleviated its pathological effects in hepatic tissue. Propolis also prevented the suppression of antioxidant enzymes in the livers of animals exposed to TCDD and displayed a strong protective effect against HMN. It can be concluded that propolis has beneficial influences and was able to antagonize TCDD toxicity in the liver.
