Abstract

Abstract: Ethnopharmacological relevance: "Zereshk-e-Saghir" (ZES), one of the traditional herbal medicines in old manuscripts of Persian hakims, has been used for the treatment of liver disorders. This current study is aimed to evaluate ZES effects on animal model to investigate its safety and hepatoprotective activity. Materials and methods: ZES was prepared according to a traditional method by blending aqueous extracts of Berberis vulgaris L., with fine particles of other plants including Rosa damascene Mill, Cichorium intybus L., Cucumis sativus L., Portulaca oleracea L., Rheum palmatum L., and Nardostachys jatamansi DC.. The lethality of ZES was determined in male NMRI mice. Acute organ toxicity of ZES (750 and 1500 mg/kg for 15 days, orally) was evaluated by measuring the cell blood count, liver marker enzymes, creatinine, antioxidant status and histopathological examinations in rats. CCl4 -induced liver toxicity was used to examine the hepatoprotective effects of the preparation. The rats were pretreated with 250, 500, 750 and 1500 mg/kg ZES by gavage for 15 days. At day 16, the rats were intraperitoneally injected 1 ml/kg CCl4 in olive oil. Forty-eight hours after CCl4 injection, the animals were sacrificed and their liver samples and blood were collected for determination of alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase (ALT, AST, and ALP), histopathological examinations and antioxidant status. Results: Treatment of the mice with a single dose of ZES up to 2 g/kg did not cause mortality. Treatment of the rats with doses of 750 and 1500 mg/kg for 15 days showed no significant hematotoxicity and hepatotoxicity. Treatment of the rats with ZES reduced the increased serum levels of ALT, AST, and ALP induced by CCl4 at the doses of 250, 500, and 750 mg/kg. This was almost confirmed by histopathological examinations. Pretreatment with ZES also decreased lipid peroxidation and maintained the levels of glutathione and total antioxidant capacity. Conclusions: The present in vivo study revealed that the long term usage of ZES was safe for organs in laboratory animals. Meanwhile, prescribing the traditionally-recommended dose of ZES can be probably used against the liver injuries induced by xenobiotics. Further studies in other models of liver injuries are recommended for finding the exact hepatoprotective mechanism of ZES. Graphical abstract:
