[Laryngeal mucosal changes experimentally produced by endogenous and exogenous factors in mice (author's transl)].

Experimentally an attempt was made to demonstrate the effects of exogenous factors on the hormonally altered laryngeal mucosa of mice. Albany mice were divided into 4 groups of 8. In the first group of males, testosterone was injected daily; in the second group of males, no testosterone was given; in the third group of females with previously removed ovaries, testosterone was given daily; and, in the fourth group of females, no testosterone was given. All 4 groups were exposed to cigarette smoke for one hour daily for six weeks. Histopathological examination of the mucosa showed that the larynx can be considered a "target" organ for male hormones and that exogenous factors produce changes that lead to malignancy.
