Abstract

To investigate the alcohol metabolizing system in liver of rats drunken 10% ethanol with Monascus pigment extract (MPE), Sprague-Dawley male rats weighing about 250 g have been drunken 10% ethanol containing 1, 2.5 and 5% Monascus pigment extract for a month. Three groups of rats drunken 10% ethanol with MPE gained somewhat less body weight than normal group, but the changes of body weight was not significantly different among the former groups. All groups drunken MPE supplemented alcohol had no remarkable changes in liver function on the basis of liver weight/body weight, the serum levels of alanine aminotransferase and xanthine oxidase activity. 10% alcohol drunken animals (control group) showed significantly increased activity of hepatic alcohol dehydrogenase (ADH) by 87% compared with normal group and the animals drunken 1%, 2.5% and 5% MPE showed respectively 34%, 29% and 21% increased activity of hepatic ADH, whileas Km value of ADH in 1, 2.5 and 5% MPE group decreased by 40%, 30% and 19% respectively compared with the control, but Vmax showed no significant changes among MPE groups. In case of aldehyde dehydrogenase (ALDH), 1% MPE group showed significantly increased activity by 32% and 2.5% or 5% MPE group showed increasing tendency compared with control, and Km value in three experimental groups declined by 27% and no particular changes were found among those. Furthermore, Vmax value in 1, 2.5 and 5% MEP group increased by 88,56 and 22% respectively with the control. In the aspect of the area under the curve of a ethanol concentration versus time (AUC) profile obtained after administration of 10% alcohol with 1 or 5% MPE, the decreasing rate of AUC to the control was 18% in 1% MPE treated rats whereas 10% in 5% MPE group.

홍국 추출물(MPE)이 알코올대사에 어떠한 영향을 미치는지를 알아보기 위하여 흰쥐에 10% ethanol에 홍국 추출물을 1%, 2.5%, 5% 함유시킨 것을 1개월간 음용시킨 뒤, 처치하여 다음과 같은 결과를 얻었다. 홍국 추출물을 첨가시킨 실험군은 정상군에 비하여 체중 증가율이 다소 낮게 나타났으며 이들 실험군 간에는 별다른 차이를 볼 수 없었다. 알코올만 투여한 대조군 및 홍국 추출물 함유 알코올 섭취군 모두 간 기능에 별다른 이상이 나타나지 않았다. 간 조직 중 alcohol dehydrogenase(ADH) 활성은 알코올 투여군이 정상군보다 87%의 유의한 증가를 보였으며 홍국 추출물 1, 2.5 및 5% 함유해서 알코올을 음용시킨 Monascus군은 알코올만 섭취한 대조군에 비해 각각 34, 29 및 21% 증가하였다. Aldehyde dehydrogenase(ALDH) 활성에 있어서는 1% Monascus군은 대조군에 비해서 32%의 유의한 증가를 보였으며, 2.5% 및 5% Monascus군 역시 대조군에 비해 증가되는 경향을 보였다. 이들 효소를 반응속도적인 측면에서 관찰해 볼 때, 1, 2.5 및 5% Monascus군은 대조군에 비하여 ADH의 Km치가 각각 40, 30 및 19% 감소되었으며, Vmax치는 알코올 투여군인 대조군은 정상군(8.26 nmole/min/mg protein)보다 43% 높게 나타났으며, 홍국 추출물함유 알코올음용군과 알코올단독음용군 간에 별다른 차이가 나타나지 않았다. 그리고 ALDH의 Vmax치는 대조군에 비해서 1, 2.5, 5% Monascus군은 대조군에 비해서 각각 88, 56, 22% 증가되었다. 한편 1% 및 5% 홍국 추출물 함유 알코올을 흰쥐에 투여한 다음 경시별로 채혈하여 혈액 중 알코올을 측정하여 알코올 농도 곡선하면적으로 환산한 결과, 1% Monascus군은 대조군에 비하여 약 18% 감소되었으며 5% Monascus군은 대조군에 비해서 약 10% 감소되는 경향을 보였다. 이상 실험 결과는 알코올에 홍국 추출물을 첨가시킴으로서 알코올대사와 더불어 알코올의 체외 배설을 촉진시키는 것을 시사해 주고 있다.
