초록

본 실험은 알코올 투여한 흰쥐를 대상으로 콩나물, 솔잎, 표고버섯과 오가피 추출물의 알코올 탈수소효소 활성과 항산화 효과를 비교하기 위해 수행되었다. 약 200g 정도의 Sprague-Dawley계 쥐들을 정상군, 알코올 단독투여군, 4가지 식물추출물 투여군으로 나우어서, 각 식물추출물을 알코올을 주입하기 전 8일 동안 200mg/kg b.w. 을 하루에 한번 경구투여하였다. 모든 동물은 알코올을 주입하고 90분 후에 도살시켰다. 콩나물과 솔잎추출물 투여군의 혈중 알코올 농도는 알코올 단독투여군, 표고버섯, 오가피군 보다 유의적으로 낮게 나타났다. 또한 콩나물과 솔잎 추출물 투여군의 알코올 탈수소효소활성은 알코올 단독투여군과 표고버섯, 오가파군보다 유의적인 증가를 보여주었다. Catalase 활성은 식물추출물 투여군이 알코올 단독투여군보다 다소 높게 나타났지만, 유의성 있는 차이는 보이지 않았다. 이러한 결과는 흰쥐에게 일회성으로 알코올을 다량 투여했을 때 알코올 탈수소효소가 catalase보다 우선적으로 알코올 대사에 반응함을 보여준다. 모든 식물추출물 투여군들의 지질과산화와 glutathione peroxidase 활성은 알코올 단독투여군보다 유의적으로 낮게 나타났다. 이 결과는 본 실험에 사용된 식물추출물들이 알코올의 산화에 대한 항산화 효과를 가진다는 것을 보여주며, 특히 콩나물과 솔잎 추출물 투여군이 알코올 탈수소효소의 활성증가오 항산화에 대한 효과가 높음을 보여주었다.

This study was purposed to compare the activity of alcohol dehydrogenase and antioxidative effects of several plant extracts in the alcohol-treated rat liver. Sprague-Dawley rat weighing about 200 g were divided into the following 6 groups : normal, alcohol group and 4 different plant extracts administrated groups(Soybean sprout, Pine needle, Lentinus edodes, acanthopanacis cortex). Each plant extract was administrated orally by 200mg/kg b.w./day for 8 days before the alcohol treatment (5 g of 30% alcohol /kg b.w. by i.p.injection). All rats were sacrificed at 90 min after the alcohol treatment. The alcohol concentrations in serum of Soybean sprout and pine needle group were significantly lower than the Lentinus edodes and Acanthopanacis cortex group. The activity of alcohol dehydrogenase in the hepatic cytosol of Soybean sprout and Pine needle group was also significantly higher than the alcohol and the other groups However, the activity of catalase seemed not to be affected, although the extract groups showed slightly higher activities of catalase than the alcohol group. These results may indicate that the extracts of Soybean sprout and Pine needle were relatvely effective on the alcohol degradation. the activity of blutathione-peroxidase and lipid peroxidaton of all of the extract groups were significantly lower than the activity of alcohol group. These results can suggest that all of the use plant extracts more or less have an antioxidative effect on the alcohol-induced oxidation and especially, extracts of Soybean sprout and Pine needle have an stimulating effect on the alcohol absorption and degradation.
