Abstract

This study was done to investigate the protective effects of ethanol extract puerariae radix(Pr) on carbon tetrachloride($CCl_4$) intoxicated rats. Male sprague Dawley rats(200~210g)was used. experimental groups were divided into normal group, $CCl_4$-control group, and ethanol extract $CCl_4$-treated group. $CCl_4$-treated groups were injected with $CCl_4$ 0.6mg/kg.b.w(i.p). The activities of Alanine aminotransferase(ALT), Aspartate aminotransferase(AST), Alkaline phosphatase(ALP), Glutamyltranspeptidase(${gamma}$-GT), Lactate dehydrogenase(LDH) in extract pretrated group was significantly decreased(p<0.05) compared to the $CCl_4$-control group. The contents of triglyceride, cholesterol and lipid peroxide were significantly decreased(p<0.05). whereas content of HDL-choresterol was significantly increased.(p<0.05). In addition, activities of hepatic catalase(CAT), glutathione peroxidase(GSH-Px) in the extract pretreated rats were significantly decreased(p<0.05) compared to the $CCl_4$-control group. but the content of glutathione(GSH) was significantly increased(p<0.05). These results suggest that extract of puerariae radix(Pr) has hepatoprotective effect in the $CCl_4$-intoxicated rats.

Dawley 계 숫컷 흰쥐(200~210g)를 정상군, $CCl_4$-대조군, $CCl_4$-실험군으로 나누어 실험군은 갈근 에탄올 추출물을 1,000mg/kg,b.w의 용량으로 1일1회7일간 경구 투여 후 사염화탄소를 0.6mg/kg,b.w의 용량으로 복강내 주사 후 다음날 개복하여 혈청내의 Alanine aminotransferase(ALT), Aspartate aminotransferase(AST), Alkaline phosphatase(ALP), Glutamyltranspeptidase(${\gamma}$-GT), Lactate dehydro-genase(LDH)의 활성도와 중성지방, 콜레스테롤 함량을 측정한 결과 갈근 추출물 투여군에서 $CCl_4$-대조군과 비교하여 유의적인 감소(p<0.05)를 나타내었으며, HDL-콜레스테롤은 유의적인 증가(P0.05)를 나타내었다. 간조직중의 지질과산화 함량과 Catalase(CAT), Glutathione peroxiddase(GSH-Px)의 항산화 효소 활성은 유의적인 감소를 나타내었다. 반면에 간 조직중의 glutathione 함량은 유의적인 증가를 나타내었다. 이 실험 결과 갈근 에탄올 추출물은 사염화탄소 투여에 의한 간 손상을 억제하는 보호물질과 항산화 물질을 함유하고 있음을 알 수 있었다.
