Persimmon is well-known as a Korean traditional medicine for alleviating coughs and enhancing blood circulation; it is also used for treatment of hypertension, cancer, diabetes and atherosclerosis. To evaluate the protective properties of persimmon leaf methanol extract (PLME) and persimmon fruit methanol extract (PFME) administration on acute ethanol-induced hepatotoxicity, C57BL/6 male mice were gavaged with or without persimmon extracts for 1 week. Hepatotoxicity was then induced by gavage of 5 g/㎏ BW ethanol. After 12 hr of ethanol administration, blood and liver were collected and analyzed for biochemical markers of hepatotoxicity. The results showed PLME and PFME treatments decreased the activities of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) compared with ethanol control. Both PLME and PFME reduced serum lactate dehydrogenase (LDH) activity, but elevated alcohol dehydrogenase (ADH) activity. Serum triglyceride (TG) and hepatic cholesterol levels were significantly decreased when treated with PLME and PFME. Liver malondialdehyde (MDA) levels were significantly decreased in PLME and PFME groups compared with ethanol control. Furthermore, the administration of PLME and PFME significantly increased the activities of catalase, glutathione peroxidase (GSH-Px) and glutathione reductase (GSH-red). In summary, PLME and PFME appeared to prevent hepatic injury by accelerating alcohol metabolism by increasing alcohol-metabolizing enzyme activities, by activating the antioxidative enzyme system against oxidative stress, and by decreasing fat accumulation, which is evidenced by decreased hepatotoxic indices in serum.
