2-Bromopropane의 수컷 랫트를 이용한 고환 독성시험

택트 스위치 제조공정 침지액의 주성분인 2-bromopropane독성에 대한 연구로 최단기의 폭로로 농도를 달리하여 3주간 반복 투여 시험을 시행하여, 흰쥐의 혈액 및 세정관의 변화를 관찰하기 위해 투여기간 동안의 체중의 변화, 고환, 간, 신장 등의 장기무게, 혈액화학과 혈액학적 분석 및 고환의 병리조직의 변화 등을 관찰하여 2-bromopropane의 급성투여 조건에서의 중독현상을 비교.분석하였다. 농도를 달리하여 투여에 따른 체중변동은 통계적으로 유의한(P 【2-Bromopropane, important industrial chemical, specially in electronic industry at Yangsan in Korea has been reported to cause amenorrhea for female and azoospermia, oligozoospermia or reduced sperm motility for male. 2-BP was investigated through 21 days of repeated dose in male Sprague-Dawley rats. The dose levels per body weight were 0 (control), 250,500 and 1,000 mg/kg. 2-BP dissolved in vehicle olive oil was injected into the intraperitoneum 6 times per week for 3 weeks, but 1,000 mg/kg dose group was 2 weeks because of serious illness. Male rats showed significant decreases in body weight and right and left testis showed typical weight losses depending on the 2-BP. The number of white blood cell and red blood cell , percentage of monocytes, and hemoglobin decreased significantly in high dose (P $\beta$ -galactosidase) and 53,900 dalton (ovalbumin) has decreased in 250 mg/kg dose group, but it has gradually increased to the higher density in 1,000 mg/kg dose group than in control group.】
