CYSTIC SQUAMOUS-CELL CARCINOMAS IN THE LUNGS OF SYRIAN GOLDEN-HAMSTERS INDUCED BY COAL OVEN FLUE EXHAUST MIXED WITH PYROLIZED TAR PITCH IN COMBINATION WITH BENZO(A)PYRENE
S. Rittinghausen et al., CYSTIC SQUAMOUS-CELL CARCINOMAS IN THE LUNGS OF SYRIAN GOLDEN-HAMSTERS INDUCED BY COAL OVEN FLUE EXHAUST MIXED WITH PYROLIZED TAR PITCH IN COMBINATION WITH BENZO(A)PYRENE, Experimental and toxicologic pathology, 49(1-2), 1997, pp. 11-14
Among a variety of induced pulmonary tumours, cystic squamous cell car
cinomas were observed in five Syrian hamsters that inhaled a mixture o
f pyrolized tar pitch with coal oven flue exhaust (PCE) and additional
ly received intratracheal injections of benzo(a)pyrene. The histologic
al appearance of these particular tumours is described, compared to si
milar tumour types in rats and the susceptibility of both species to i
nert particles is discussed.
