Fig. 1. Angiotensin-II plasma levels in rats exposed to fine PM.
Adult Sprague Dawley rats treated with saline, Benazepril or Valsartan were exposed to fine PM or filtered air for 5 hours in the HFPC. Blood samples were collected at the end of the exposure and processed for the determination of angiotensin-II in plasma, as described in the Methods section. Bars represent the mean value of 4-5 independent experiments. * p <0.002 vs. control. † p< 0.05 vs. PM.
