The effect of cigarette smoke exposure in European hamsters.
The effects of 2 types of research cigarettes, differing in their total smoke delivery and condensate were examined. Two groups of European hamsters were exposed in a smoking chamber to the cigarette smoke of both types of cigarettes for 130 weeks. Exposure related alterations were found in the respiratory tract and forestomach. However, smoke exposure over this period had no effect on mortality and led to no neoplastic response.
