[Benzopyrene (BaP) implants into the glottic mucous membrane of hamsters].
For testing the effect of benzo (a) pyrene (BaP) on glottical epithelium European hamsters were used. With laryngofissure hamsters larynges had been opened and a mixture of tricaprilin, beewax and 1 mg BaP was implanted into a pocket formed by mucous membrane of one vocal fold. Compared to typical histology in smoker's larynx, squamous metaplasia and dysplasia and in one case papillary polyps could be described. No squamous cell carcinomata was found.
