Abstract in Portuguese
Objetivo: checar se poluentes do ar urbano de São Paulo induzem alterações sangüíneas e cardiopulmonares. MM: camundongos Balb/c foram expostos por 7, 14, 21, 30 e 45 dias em 3 câmaras: Limpa (controle), Intermediária (seletiva ao PM) e Suja (ar externo). Após exposição, os animais foram ventilados (FlexiVent) e coletados dados de mecânica pulmonar, sangue, coração e pulmão. Foram registrados PM, CO, SO2 e NO2 diários. Resultados: aos 21 e 45 dias coincidentes com picos de poluição houve aumento da resistência de via aérea (45d p=0,012), leucocitose (21d p < 0,001 e 45d p=0,039) e vasoconstricção pulmonar (21d p=0,034) nos animais da Câmara Suja, sem alteração de coronárias. Nenhum poluente excedeu limites de qualidade de ar

Abstract in English
Objective: verify if air pollution of São Paulo city induces alterations in blood and cardiopulmonary systems. MM: Balb/c mice were exposed during 7, 14, 21, 30 and 45 days to 3 chambers: Clean (control), Intermediate (PM only) and Dirty (external air). After exposure, animals were ventilated (FlexiVent) and collected lung mechanics data and blood, heart and lung. PM, CO, SO2 e NO2 were measured daily. Results: on day 21 and 45, coincidently to peak of pollutions, there was proximal airway resistance increase (45d p=0.012), leukocytosis (21d p < 0.001 and 45d p=0.039) and vasoconstriction of peribronchiolar arterioles (21d p=0.034) in animals of Dirty Chamber with no alterations of coronaries. Neither pollutants exceeded the standard limits
