Lee HS, Jung KH, Hong SW, Park IS, Lee C, Han HK, Lee DH, Hong SS: Morin protects acute liver damage by carbon tetrachloride (CCl (4)) in rat. Toxicol Appl Pharmacol. 2008 Jan 1;226(1):38-45. Epub 2007 Aug 24.
The purpose of this study was to investigate possible beneficial effects of morin on CCl (4)-induced acute hepatotoxicity in rats. Rats received a single dose of CCl (4) (150 microL/100 g 1:1 in corn oil). Morin treatment (20 mg/kg) was given at 48, 24, and 2 h before CCl (4) administration. CCl (4) challenge elevated serum alanine transaminase (ALT), aspartate transaminase (AST), and alkaline phosphatase (ALP) levels, but these effects were prevented by the pretreatment of rats with morin. To identify the mechanism of protective activity of morin in CCl (4)-induced hepatotoxicity in rats, we investigated expressions of tumor necrosis factor alpha (TNF-alpha), interleukin-1beta (IL-1beta), interleukin-6 (IL-6), and inducible nitric oxide (iNOS). The expressions of TNF-alpha, IL-1beta, IL-6, and iNOS were increased by CCl (4) treatment and increased expressions of those were decreased by morin. These findings suggest that morin prevents acute liver damage by inhibiting the production of TNF-alpha, IL-1beta, IL-6, and iNOS. |
