Abstract

1,2-Dibromo-3-chloropropane (DBCP) was inhaled by B6C3F1 mice of each sex at concentrations of 0.6 or 3.0 ppm for 6 h/day, 5 days/week, for 103 weeks. Untreated controls consisted of 50 mice of each sex. All surviving animals were killed at 104 weeks. Survival in the high-dose groups of female mice was significantly shorter than that in the corresponding controls. Alveolar-bronchiolar adenomas or carcinomas occurred in both male and female mice with dose-related trends (P < 0.007) in males and (P < 0.002) in females. Papillary carcinomas in the lung occurred in low-dose female mice at an increased incidence compared with controls (P < 0.006). Many induced tumors were morphologically different than those in controls.

摘要

将1,2 - 二溴 - 3 - 氯丙烷(DBCP)以0.6或3.0 ppm的浓度让各性别B6C3F1小鼠吸入,每天6小时,每周5天,持续103周。未处理的对照组由各50只各性别的小鼠组成。所有存活的动物在104周时处死。高剂量组雌性小鼠的生存期显著短于相应的对照组。雄性和雌性小鼠均出现肺泡 - 细支气管腺瘤或癌,雄性呈现剂量相关趋势(P < 0.007),雌性呈现剂量相关趋势(P < 0.002)。低剂量雌性小鼠肺部乳头状癌的发生率高于对照组(P < 0.006)。许多诱发肿瘤在形态上与对照组不同。
