영문 초록

The hepatoprotection by the methanol extract of Oenanthe javanica DC (water dropwort) (OJME) was investigated in Sprague Dawley rats with inducing liver damage by acetaminophen. After OJME administration for 1 week, the increase of hepatic lipid peroxide level by acetaminophen-induced hepatotoxicity was significantly reduced. In case of phase I microsomal enzyme systems including cytochrome P-450, aminopyrine N-demethylase and aniline hydroxylase, any significant differences between in control and in OJME-pretreated group was observed after acetaminophen treatment. However, the pretreatment of OJME maintained the hepatic glutathione level and the activity of liver cytosolic glutathione Stransferase, which was significantly decreased by the acetaminophen intoxication. Among the glutathione-generating system, glutathione reductase was more responsible for its biosynthesis rather than γ-glutamylcystein synthetase. OJME itself showed the strong inhibition activity on DPPH radical generation. In conclusion, OJME administration maintains the liver glutathione pool and hepatic glutathione S-transferase activity, in addition with its high anti-oxidative capability, to show hepatoprotective effect from acetaminophen intoxication.
