摘要:
This study aimed to verify the development of placental and systemic inflammation in rats exposed to fine particulate matter before or during pregnancy. Wistar rats were exposed to filtered air ( control) or to a load of 600 mu g/m(3) of fine particles in the air. The gene expression of IL-1 beta, IL-4, IL-6, IL-10, INF-gamma, TNF-alpha and Toll-like receptor 4 in the placenta was evaluated. The serum and placental concentrations of IL-1 beta, IL-4, IL-6, IL-10, INF-gamma and TNF-alpha were measured. The total and differential blood leukocyte and blood platelet count was assessed. Compared to control animals, IL-4 content was elevated in the fetal portion of the placenta in rats exposed to air pollution before and during pregnancy. Increased IL-4 suggests that a placental inflammatory reaction may have occurred in response to exposure to fine particulate matter and that this cytokine was responsible, among possibly others factors, for resolution of the inflammatory reaction.
