Abstract
Several epidemiological studies have shown that acute exposure to particulate air pollution is associated with increases in cardiovascular morbidity and mortality, and that these effects are especially exacerbated among individuals with pre-existing compromised cardiovascular function such as hypertension. This study was undertaken to determine the cardiovascular effect of diesel exhaust on TO mice made hypertensive by implanting osmotic minipump infusing angiotensin II or vehicle (control). On day 13, the animals were intratracheally instilled with either DEP (15μg/mouse) or saline. 24h later, pulmonary exposure to DEP had significantly decreased the systolic blood pressure (SBP) in hypertensive (HT) mice (P2 was decreased, and PaCO2 increased in DEP-treated HT mice compared to NT mice treated with DEP (P
