title: Methodoloigcal study on examiniation of primary tumors of the respiratory tract "in toto" and histologically.
abstract: The results of histological evaluation of DENA-induced tracheobronchial tumors in the Syrian golden hamster are described and compared with those of an in toto method of visualization. In 55 animals, roughly twice as many tumors were detected in the lungs in the in toto preparation as those found by the histological technique [92:42]. The examiniation of the respiratory tract, as a whole, would consequently appear to afford an efficient and economical means of quantifying the effects of, for instance, chemotherapeutic agents in the growth of such tumors, which can subsequently be complemented, especially in the qualitative sense, by histological techniques.
