摘要

쥐에서 carbofuran 대사에 미치는 phenobarbital sodium (PB) 또는 3-methylcholanthrene (3-MC)의 영향을 조사하기 위하여 쥐에 이들을 단독 또는 조합으로 경구투여한 후 일정 간격으로 쥐의 주요 장기, 대변, 소변 및 혈액 중 대사산물의 종류와 생성율을 조사하였다. Carbofuran 단독투여와 carbofuran과 PB 또는 3-MC 조합투여 모두 경구투여 후 48시간 이내에 빠르게 배설되어 $^{14}C$-carbofuran 총 투여량의 79.9$\sim$81.1%가 소변으로, 5.7$\sim$6.5%가 대변으로 배설되었는데, 배설속도는 carbofuran 단독투여 보다 carbofuran과 PB 또는 3-MC 조합투여에서 빨랐다. 쥐의 주요 장기, 대소변 및 혈액 중의 carbofuran의 대사산물은 공통적으로 3-hydroxycarbofuran, 3-ketorarbofuran, 3-hydroxycarbofuran phenol, 3-ketocarbofuran phenol과 carbofuran phenol이었고, 주요 대사산물은 3-hydroxycarbofuran과 3-ketocarbofuran이었는데, 주요 대사산물의 경우 carbofuran만의 투여에서는 3-hydroxycarbofuran이었으나 carbofuran과 PB 또는 3-MC 조합투여는 3-ketocarbofuran이었다. 소변 중 carbofuran의 2가지 주 대사산물의 생성율은 carbofuran 단독투여시 3-hydroxycarbofuran 17.4%와 3-ketocarbofuran 12.8%이었고, carbofuran과 PB 또는 3-MC 조합투여시 3-hydroxycarbofuran 8.6%와 3-ketocarbofuran 23.5%로서, carbofuran 단독투여와 carbofuran과 PB 또는 3-MC 투여사이에 대사산물의 종류는 같았으나 생성율에는 큰 차이가 있었다. 이와 같은 결과는 쥐에 carbofuran 투여 후 PB나 3-MC를 투여함으로써 carbofuran의 대사가 빠르게 이루어지고, 주 대사산물 중3-hydroxycarbofuran보다 독성 이 낮은 3-ketocarbofuran으로의 대사가 빠르게 이루어지기 때문에 carbofuran의 독성이 경감되어 쥐가 생존할 수 있는 것으로 판단된다. In order to elucidate the effect of phenobarbital sodium (PB) and 3-methylcholanthrene (3-MC) on metabolism of insecticide carbofuran in rat. Carbofuran metabolites and its formation rates were determined when orally administered $^{14}C$-carbofuran alone and its combination with PB or 3-MC to rat. $^{14}C$-carbofuran administered orally, alone or in combination with PB or 3-MC, was secreted rapidly within 48 hrs. That is, 79.9 to 81.1% of the original radioactivity was secreted into the urine and 5.7 to 6.5% into the feces. The secretion rate was faster in the combined administration than that in carbofuran alone. Metabolites of carbofuran in main organs, urine, feces and blood of rat were largely 3-hydroxycarbofuran, 3-ketocarbofuran, 3-hydroxycarbofuran phenol, 3-ketocarbofuran phenol, and carbofuran phenol, the major ones being 3-hydroxycarbofuran and 3-ketocarbofuran, respectively, in all administrations of carbofuran alone, carbofuran+PB and carbofuran+3-MC. In addition, formation rate of the two major metabolites detected in the urine was 17.4% and 12.8%, respectively, when carbofuran alone was administered. Meanwhile, when carbofuran was administered with PB or 3-MC, they were 8.6% and 23.5, repectively. These results indicate that the oral administration of PB or 3-MC can reduce carbofuran toxicity by fastening and stimulating the carbofuran metabolism in rat.
