Inhalation experiments with 14C-labelled cigarette smoke. III. Body size dependent distribution of particulate matter in small rodents during cigarette smoke inhalation.

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.

Morphology of spontaneous and induced tumors in the bronchiolo-alveolar region of F344 rats.

The morphology of spontaneous and chemically-induced metastasizing carcinomas and adenomas in the bronchiolo-alveolar region of F-344 rats was studied. Histologically, the tumors were tubulo-papillary. Ultra-structurally, they consisted of cells which formed and secreted osmiophilic lamellated inclusion bodies, a marker of alveolar type II cells. Mitotic tumor cells also demonstrated such bodies. No cells of bronchial or bronchiolar origin were found in the tumors. We conclude that in F344 rats, lung tumors located in the bronchioloalveolar region consist of alveolar type II cells exclusively and are, therefore, alveolar cell adenomas and carcinomas, respectively.

Lung cancer following exposure to bis(chloromethyl)ether: a case report.

A research chemist (non-smoker) worked for two years on an investigation where bis(chloromethyl)ether (BCME) and chloromethyl methyl ether (CMME) were by-products. Twelve years after completion of the study he died of a pulmonary adenocarcinoma that had metastasized to both the bones and soft tissue. The relatively large scale (1--2 mol) on which the chemical reaction was conducted resulted in his inhalation of high doses of both BCME and CMME for this two year period. His case history is discussed with reference to other such reported instances.
