Abstract

Syrian golden and European hamsters were exposed to 14C-labelled cigarette smoke. The deposition of the 14C activity in the respiratory and digestive tracts was determined immediately after the exposure. From the results obtained it can be seen that the distribution of particulate matter between the upper and lower respiratory tract, as well as, between the respiratory and digestive tracts is related to the body weight of the experimental animals.

摘要

叙利亚金黄地鼠和欧洲仓鼠被暴露于含14C标记的香烟烟雾中。暴露后立即测定呼吸道和消化道中14C活性的沉积情况。从所得结果可以看出,颗粒物在上呼吸道和下呼吸道之间以及呼吸道和消化道之间的分布与实验动物的体重有关。
