Urban, traffic- related particles and lung tumors in urethane treated mice

Abstract: OBJECTIVE:The present study was designed to evaluate the effects of urban, traffic-related, fine particulate matter (PM2.5) on mice lung tumorigenesis under controlled exposure conditions.METHODS:Four groups of female Swiss mice were treated with intraperitonial injections of urethane and saline solution. Urethane was used to start the carcinogenesis process. The animals were housed in two chambers receiving filtered and polluted air. In the polluted air chamber, pollutant levels were low. After two months of … Show more

“…Isso foi comprovado por estudos experimentais e epidemiológicos. Reymao (1997) mostrou que ratos expostos à poluição atmosférica urbana tiveram maior formação de tumores de pulmão, induzidos por uretana; e a concentração urbana de poluição do ar modificou a progressão de tumores de pulmão induzida em camundongos (CURY et al, 2000;PEREIRA et al, 2011). ;HARVEY, 1990;FISHER, 2004;SMEDBY,2006).…”
