Figure 6. The correlation of increases in nitric oxide (NO) concentration with bradykinin-induced increases in coronary flow in the absence and presence of 1% isoflurane (A) and 2% isoflurane (B). Each slope is significant. There is no difference between control and isoflurane slopes. The Y intercepts for 1% and 2% isoflurane are significantly (P < 0.05). See Figure 4for other details.
