Figure 3. Effect of cocaine on myogenic tone in male coronary arteries.
Pressure-dependent myogenic tone was determined in the absence or presence of L-NNA (100 µM, 20 min) in coronary arteries from 3 month old male offspring that had been exposed in utero to saline control or cocaine. Data are means ± SEM. * P < 0.05, cocaine versus control. n=6–8 rats.
