Ascorbic Acid 및 김치가 다환 방향족 탄화수소 섭취 Guinea Pigs 의생체 이물 대사에 미치는 영향
Effect of Ascorbic Acid and Kimchi on the Metabolism of Xenobiotics in Guinea Pigs Administered Polycyclic Aromatic Hydrocarbon
초록
The effect of ascorbic acid (AsA) or kimchi on the metabolism of xenobiotics in guinea pig administered policyclic aromatic hydrocarbons(PAH) an environmental pollutant was inves-tigated. Guinea pigs given oral supplementation were divided into 4 groups. Group A(control) was supplemented with 2mg of AsA/day group B with 2mg of AsA and PAH/day gruop C with 50mg of AsA and PAH/day. Changes of liver cytochrome P-450 contents and 7-ethoxycou-marin O-deethylase(ECOD) activity glutamate-oxaloacetate transferase(GOT) activity in serum and AsA contents in various tissues were determined. Cytochrome P-450 contents ECOD activity and GOT activity increased in B, C and D groups administered PAH. Moreover cytoch-rome P=450 contents and ECOD activity in group C were higher than those of group A and D. The content of AsA in the tissues of group B was lower than that of A, C and D groups respectively. These results suggested that AsA was necessary in the PAH metabolism moreo-ver supplementation of large amount of AsA or kimchi in the guinea administered PAH had an influence in the drug-metabolizing enzyme induction thus caused a decrease of AsA in tissues.
