Quinolone계 항균제의 일종인 pefloxacin을 넙치에 투여한 후, HPLC를 이용하여 약물의 분포도를 살펴보았다. 100 mg/kg의 pefloxacin을 넙치에 이틀 연속 경구투여한 후, 넙치의 혈액, 근육 및 간을 포함한 8개의 장기를 분석한 결과, pefloxacin은 장을 통하여 흡수되며 담낭에 축적됨을 알았다. 약물 투여 후 45분에 <TEX>$4.70{\mu}g/ml$</TEX>로 혈액내 농도가 최대치를 나타냈으며, 11일째에는 <TEX>$0.31{\pm}0.01{\mu}g/ml$</TEX>이 검출되었다. 근육조직에서는 10일째까지 <TEX>$0.29{\pm}0.02{\mu}g/g$</TEX> tissue가 잔류하였다.
This study showed the distribution of pefloxacin as a kind of quinolones after oral administrations of 100 mg/kg pefloxacin for 2 days in flounder. After administrations of pefloxacin, blood, muscle, and 8 organs including liver of flounder were analyzed by HPLC. In results, we knew that pefloxacin had absorbed from intestine and accumulated into gall bladder. In blood, maximum plasma concentration was showed <TEX>$4.70{\mu}g/ml$</TEX> at 45min, and detected <TEX>$0.31{\pm}0.01{\mu}g/ml$</TEX> at 11th day after administration. The concentration of pefloxacin was remained <TEX>$0.29{\pm}0.02{\mu}g/g$</TEX> tissue in muscle at 10th day.
