Abstract

Abstract Objectives Teucrium polium (TP) has been traditionally used for treatment of the diabetes mellitus, kidney and liver diseases, and inflammations but some studies have reported the hepatotoxicity effects of this plant. Therefore, this study was conducted to investigate the effect of TP aqueous extract on the liver of the diabetic rats. Methods Adult male Wistar rats were randomly divided into five groups: (Control) Normal rats that were gavaged with normal saline (1 mL), (TP100) Normal rats (Non-diabetic) that were gavaged with TP (100 mg/kg), (DM) diabetic model rats, which became diabetic by intraperitoneal injection of streptozotocin (50 mg/kg), (DTP100) diabetic rats that were gavaged with TP (100 mg/kg), and (DTP200) diabetic rats that were gavaged with TP (200 mg/kg). The effects of the aqueous extract on the blood glucose, body weight, the activities of enzyme markers of liver damage (Aspartate Aminotransferase (AST) and Alanine Aminotransferase (ALT)) were investigated in the serum of the control and treated groups. At the end of study liver histopathology and the total antioxidant activity (TAA) test were evaluated. Finally, obtained data were analyzed by the SPSS software (version 16). Results Results showed that the AST and ALT levels were significantly increased in the diabetic rats (p<0.001). A comparison of 100 mg/kg and 200 mg/kg doses of TP administration in diabetic rats also showed a significant difference (p=0.01), indicating a better performance of 100 mg/kg dose. No significant difference was found between the control group and rats treated by the TP (TP100) (p=0.382). Also, triglyceride (TG) and cholesterol levels were significantly decreased in the treated groups compared to the diabetic untreated group. Conclusions Findings of the study revealed no hepatotoxicity, and the hepatoprotective effects of the TP were proved in the present study.
