“…With these findings, the researchers recommend the need to limit biomass burning and that smoking cessation encouragement be emphasized in the population exposed to the combination of these two risk factors. In an experimental model of mice exposed to tobacco smoke and residual oil fly ash (ROFA -diesel burn waste), Biselli et al 50 evaluated the presence of lung lesions in the animals exposed to fossil fuel burning and cigarette smoke inhaling, separately and combined, for two months. The combined exposure group showed an joined effect of the two environmental risk factors on the most frequently studied lung abnormalities (airway wall thickening, end-terminal airspace dilation and inflammatory infiltrate), followed by the group exposed to inhaled cigarette smoke and nasal instillation of a suspension of particulate matter from fossil fuels, thereby enhancing the combined effect of both types of exposure.…”

“…The flap dimensions were 2.5x10cm and after 28 days of tobacco exposure, the necrosis was 78.2%. Necrosis found in our study was different for several reasons; one reason was the flap dimensions (2.5x10cm versus 3x10cm Moreover, it was difficult to reproduce the equipment used in Nolan et al 14 , thus, we adopted the model of Biselli et al because it was a feasible and reproducible equipment 12,14 . We consider these results methodological steps to define this tobacco exposure model as feasible and reproducible.…”

“…However, to reproduce a clinical condition, we believe that nicotine injection was inadequate. The cigarette had more than one thousand of substances that can interfere with flap survival, and for this reason we adopted this model 12 .…”

“…No presente estudo realizamos exposição a uma mistura de fumaça central e lateral do cigarro para mimetizar o fumo passivo. A monitorização ambiental da exposição demonstrou resultados semelhantes ao observado em trabalho anterior de nosso grupo (TORRES et al, 2012) e também por Biselli et al (2011). Em estudo anterior avaliamos os efeitos da fumaça do cigarro no estresse oxidativo no SNC de camundongos jovens por meio da exposição diária (2 horas/dia) durante 14 dias e observamos concentração de CO de 500,9 ± 158,6 ppm (TORRES et al, 2012 (OBOT et al, 2004).…”
