Chlorpyrifos induces hypertension in rats
This study using a non-invasive measurement with a working range from 0–300 mm Hg and a silent built-in air pump that ensured automated cuff inflation/deflation at a constant rate blood pressure (BP) demonstrated an initially elevated BP in all treatment groups for several hours after exposure. This parameter was monitored for 3 and 14 days. BP was elevated at 3- and 14 –day exposure, but not...
