Abstract

The purpose of this study was to investigate the preventive effects of Paeoniae Radix Extract(PRE) against the acute hepatotoxicity-inducing lipopolysaccharide(LPS) in the liver. PRE of 100 mg/kg concentration was intraperitoneally administered into rats at dose of 1.5 ml/kg for 20 days. On day 21, 5 mg/kg of LPS dissolved in saline was injected 4 hours before anesthetization. We examined the levels of glutamate oxaloacetate transaminase(GOT), glutamate pyruvate transaminase(GPT), lactate dehydrogenase(LDH) in serum of rats, superoxide dismutase(SOD) in mitochondrial fractions, and malondialdehyde(MDA), catalase(CAT), glutathione peroxidase(GPx) in liver homogenates. LPS-treatment markedly increased the levels of GOT, GPT, LDH and MDA, and significantly decreased those of SOD, CAT and GPx. But PRE-pretreatment decreased the levels of GOT, GPT, LDH and MDA, by 59.7%, 43.6%, 59.6% and 63.5%, respectively and increased those of SOD, CAT and GPx, by 85.5%, 57.8% and 62.9%, respectively. These results showed that the PRE had the preventive effects against the acute hepatotoxicity-inducing LPS in the liver.

본 연구에서는 한방에서 약용으로 사용하고 있는 미나리 재비과에 속하는 다년생 초본으로 백작약의 열수 추출물을 이용하여 LPS로 유발된 급성 간독성에서의 간 보호효과를 나타내는지 살펴보고자 하였다. 간독성이 유발된 쥐의 혈청에서의 GOT, GPT 그리고 LDH의 감소는 백작약 추출물이 간독성으로부터 간을 보호하였음을 보여주며, 간조직에서의 MDA 감소 및 SOD, CAT, GPx의 활성도 증가 역시 백작약 추출물이 간독성으로부터 간의 기능이 회복됨을 볼 수 있었다. 이러한 결과는 백작약 추출물이 LPS로 유발된 급성 간손상에 대한 보호물질로서의 가능성을 확인할 수 있었다.
