Abstract

Weekly intragastric administration of 20, 40, and 80 mg/kg body weight diallylnitrosamine to BD IX rats selectively induced nasal and paranasal cavity tumors with incidences of 30%, 85%, and 65% in females and of 0%, 75%, and 80% in males, respectively. All tumors were carcinomas of the olfactory region, and 95% were invasive. Only a few papillomas in the anterior region were found simultaneously with the carcinomas.

摘要

每周给BD IX大鼠胃内注射20、40和80毫克/千克体重的二烯丙基亚硝胺,可选择性地诱发鼻腔和鼻窦肿瘤,雌性大鼠的发病率分别为30%、85%和65%,雄性大鼠的发病率分别为0%、75%和80%。所有肿瘤均为嗅区癌,95%为浸润性癌。仅在前部区域发现少数乳头状瘤与癌同时存在。
