Abstract

This study was performed to evaluate repeated dose oral toxicity upon administration of the test substance 1,2-benzisothiazolin-3-one for 90 days and to determine NOAEL (no observed adverse effect level) and target organs in Sprague-Dawley rats. Single, 2-week repeated, and 13-week repeated oral dose toxicity studies were conducted in Sprague-Dawley rats. The dose levels of groups were 1,250, 2,500, and 5,000 mg/kg/d. All dose groups were compared with the vehicle control group. The animals were observed for clinical signs and weekly body weight. Urinalysis, hematology, and serum biochemistry analyses were conducted. Subsequently, animals were sacrificed and subjected to histopathological examination. For the result, NOAEL of ethanol extract from unripe fruit of bitter melon had an optimal dose of 5,000 mg/kg/d and acceptable daily intake up to 3,000 mg/man. There was no target organ detected. Therefore, bitter melon, which contains a variety of bioactive substances, could be widely used as a health functional food ingredient.

본 연구에서는 항당뇨에 유효성이 있는 천연물질인 여주 추출물을 이용하여 여주에 포함된 독성물질인 vicine의 분석과 경구투여에 따른 독성을 조사하기 위하여 단회 경구투여 독성시험과 13주 반복 경구투여 독성시험을 진행하였다. 본 시료는 여주 미숙과 열매추출물로 vicine의 분석 결과 존재하지 않거나 극미량일 것으로 판단된다. 단회 경구투여 독성 시험과 시험물질에 의한 이상증상과 사망동물은 발생하지 않아 여주 추출물의 ALD는 암수 모두 5,000 mg/kg/d 이상으로 판단된다. 13주 반복 경구투여 독성시험의 투여용량을 결정하기 위하여 0, 1,250, 2,500 및 5,000 mg/kg/d의 투여용량으로 2주 반복투여 용량결정시험을 실시한 결과, 모든 시험군에서 시험물질에 의한 이상증상 및 독성 변화가 관찰되지 않아 동일한 용량으로 13주 반복 경구투여 독성시험을 진행하였다. 실험기간 동안 사망률, 일반증상, 체중 변화, 사료섭취량, 안검사, 요검사, 혈액학적 검사, 혈액응고시간 검사, 혈액생화학적 검사, 부검소견, 장기중량 및 조직병리학적 소견을 관찰한 결과, 시험물질에 의한 전신적인 독성학적 변화는 관찰되지 않았다. 따라서 여주 추출물의 NOAEL은 5,000 mg/kg/d로 판단되었고, 표적장기는 관찰되지 않았다. 본 연구의 결과로 볼 때 여주 추출물은 투여 가능한 최대 용량에서도 독성이 나타나지 않는 안전한 천연물로 확인하였고, 본 시험 결과를 바탕으로 ADI는 3,000 mg/man으로 판단된다. 따라서 기능성 식품으로서의 개발 가능성을 확인하였다.
