초록

<TEX>$^{14}C$</TEX>-warfarin을 흰쥐에 경구투여 후 4시간 경과시 혈액에서 최고치를 나타내었으며, coumarin과 그 유도체인 warfarin에 의한 간조직 microsome 내의 Cyt. p-450은 이들 화합물에 의해 microsomal electron transport system이 증가됨과 Cyt. p-450의 isozyme들이 유도됨을 확인할 수 있었다.

Abstract

The <TEX>$^{14}C$</TEX>-warfarin used as rodenticids was identified from various organs of sprague dawley with scintillation counter. And the cytochrome p-450 which was induced by coumarin derivatives was identified with electrophoresis. The distributions of <TEX>$^{14}C$</TEX>-warfarin after <TEX>$14.8{\mu}Ci/kg$</TEX> oral application at each organ was as follows; urine-7.5%, blood-0.44%, feces-0.9%, liver-0.66%, lung-0.86%, kidney-0.8%, heart-0.43% and spreen-0.33% after 24hrs. The cytochrome p-450 was purified by Octyl Sepharose CL-4B hydrophobic chromatography and isozymes were 50.8 Kd in control group, 53.3 Kd and 55.2 Kd in coumarin pretreated group and 50.8 Kd, 54.6 Kd and 57.7 Kd in warfarin pretreated group.
