Abstract
Follicular neoplasms of the thyroid gland developed in 79 of 200 Fischer 344 rats of both sexes, fed either 0.0375% or 0.075% 4,4'-methylene-bis-(N,N-dimethyl)-benzenamine (MDBA) mixed with the diet. Hyperplastic changes in the follicular epithelium occurred in 12 rats fed the higher concentration of this chemical. One of 40 control rats had a follicular carcinoma of the thyroid gland.
摘要
在200只雌雄Fischer 344大鼠中，79只喂食了含0.0375%或0.075% 4,4'-亚甲基双（N,N-二甲基）苯胺（MDBA）的混合饲料，甲状腺出现了滤泡性肿瘤。12只喂食该化学物质较高浓度饲料的大鼠，其滤泡上皮发生了增生性变化。40只对照大鼠中有1只患有甲状腺滤泡癌。
