Abstract

This study was done to investigate the effects of Artemisia selengensis methanol extract on ethanol-induced hepatotoxicty in rat liver. Sprague-Dawley(SD) rats weighing about 150g were divided into the following 4 groups : control group(CON), Astemisia selengensis methanol extract administered group(ASE), ethanol adminstered group(ETH) and Artemisia selengenis methanol extract and ethanol administered group(ASA). Ethanol and Artemisia selengenis methanol extract were administered orally by 5m1/kg and 200mg/kg body weight per day for 6weeks, respectively. Body weight, daily food intake and percent liver weight per body weight were significantly changed by ethanol administration in comparison to control group. The activities of serum alanine aminotransferase(ALT), asparate aminotransferase(AST), and hepatic TBA-reactants increased by ethanol were decreased significantly by Artemisia selengensis methanol extract compared with ethanol group. It was also obseued that superoxide dismutase, catalase and glutathione peroxidase were not changed by Artemisia selengensis methanol extract, whereas hepatic xanthine oxidase activity was inhibitied by Artemisia selengensis methanol extract as compared to ethanol group. The glutathione contents in liver decreased by ethanol adminstration, but glutathione levels increased in ASA compared with ethanol group. These results suggest that Artemisia selengenis methanol extract have a possible protective effect on the ethanol-induced hepatotoxicity in rat liver.

물쑥추출물이 에탄올에 의한 횐쥐의 간손상에 미치는 영향을 알아보기 위하여 정상군, 물쑥추출물 투여군, 에탄을 투여군 및 에탄올과 물쑥추출물 병합투여군으로 나누어 6주간 사육하여 식이 섭취량, 체중 및 간장의 무게, 혈청 중의 AST, ALT 및 ALP 활성, 간장 중의 TBA반응성 산물량, SOD, catalase, GSH-PX 및 xanthine oxidase의 활성 및 GSH의 함량에 미치는 영향을 관찰하였다 : 1) 에탄올 섭취군이 정상군 보다 체중 및 식이 섭취량이 유의적으로 감소되었다. 2) 물쑥추출물은 에탄올 투여로 증가된 휜쥐의 혈청 중 AST ALT의 활성을 에탄올 투여군에 비하여 유의성있는 감소 효과를 나타냈다(p<0.05). 또한 물쑥추출물은 증가된 간 TBA-반응성 물질 함량을 유의성있게 감소시켰다(p<0.05). 3) 물쑥추출물은 유리기 생성계의 효소인 xanthine oxidase 활성을 에탄올 투여군에 비하여 약 25% 정도 현저하게 감소시켰다(p<0.05). 그러나 유리기 해독계 요소인 SOD, catalase 및 GSH-PX 활성에 대해서는 약간의 변화는 있었으나 유의한 변화를 나타내지 않았다. 4) 물쑥추출물은 에탄을 투여로 감소된 간 GSH함량을 에탄올 투여군에 비하여 유의하게 증가시켰다. 이상의 실험 결과와 문헌상의 지견을 종합하여 볼 때 에탄올 투여로 증가된 간 지질과산화물 생성계 효소인 xanthine oxidase활성억제와 비효소적 항산화작용을 나타내는 GSH 함량을 증가시킴으로서 산화물에 대한 방어력이 증강되어 나타난 결과로 여겨지며, 또한 혈청 중의 AST, ALT및 ALP효소 활성을 유의성있게 감소시켰음은 물쑥추출물이 에탄올에 의한 간세포손상에 대한 방지 작용이 있는 것으로 사료된다.
