칡추출물이 알코올성 뇌손상에 미치는 영향 을 구명하기 위해 알코올을 투여한 흰쥐에게 갈화와 갈근을 수준별 (I;1.2 g/kg B.W., II;2.4 g/kg B.W.) 로 5주간 급여한 후 \ulcorner 열수추출물이 알코올 대사와 유리기 생성 및 제거효소 활성에 미치는 영향을 관찰하였다. ADH 활성응ㄴ 갈화 및 갈근추출물 급여시 에탄올만 투 여한 대조군에 비하여 유의적으로 감소한 반면, ALDH 활성은 갈근추출물 급여군에서 유의 적으로 증가하였는데 1수준군의 증가정도가 현저하였다. P450 함량과 AD, AH 활성은 대조 ...
This study investigated the effect of Puerariae Flos (PF; flower of Puerariae plant) and Puerariae Radix (PR; root of Puerariae plant) water extracts on the activities on the activities of ethanol-metabolizing enzymes and free radical generating/scavenging enzymes of brain in ethanol-treated rats. Five groups of male Sprague-Dawley rats were orally administered ethanol (25%, v/v) 5 g/kg body weight/day, and sacrificed 5 weeks post treatment. PF and PR water extracts were supplemented in a diet based on 1.2g (I) or 2.4 g (II) raw PF or PR/kg body weight/day. Alcohol dehydrogenase activity of brain was significantly lowered in PF of PR groups, whereas aldehyde dehydrogenase activity was significantly higher in PR groups than those of control and PF groups. Cytochrome P-450 content, aminopyrine D-methylase and aniline hydroxylase activities were decreased in both PF and PR groups compared to control group. Aldehyde oxidase and xanthine oxidase activities tended to decrease by Puerariae plant extract supplemented goups and degree of decrease predominated in PRI. Superoxide dismutase and glutathione S-transferase activities were increased in PF or PR groups, whereas glutathione peroxidase and catalase activities were significantly decrased by Puerariae plant extracts supplement. These results indicated that supplementation of PF or PR lowers free radical generating enzymes activities. It was suggested that the activities of ethanol metabolizing emzymes and antioxidant enzymes in brain can be enhanced by PF or PR supplement in ethanol-treated rats.
