Figure 7. Vasodilating action of volatile anesthetics in high Potassium sup +-treated endothelium-denuded strips in the presence (right) or absence (left) of ryanodine (10 micro Meter) at (A) 22 degrees Celsius and (B) 35 degrees Celsius. No significant differences were observed in vasodilating action among three volatile anesthetics under each condition. The IC⁵⁰values for the vasodilating actions of volatile anesthetics under each condition are shown in Table 2. All values are displayed as mean plus/minus SEM (n = 7–11, six animals).
