Figure 7From: Induction of lung lesions in Wistar rats by 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone and its inhibition by aspirin and phenethyl isothiocyanate Aspirin and/or PEITC inhibit lung tumorigenesis in Wistar rats after NNK instillation. Treatment with aspirin and/or PEITC reduced alveolar dysplasia and improved lung structure after 91 days. A, NNK-treated group; B, aspirin group; C, aspirin and PEITC group.
