(A) Increase in mean arterial pressure (MAP, mmHg) and (B) decrease in heart rate (HR, bpm) in response to phenilephrine (PHE, 8 μg/kg i.v., bolus) in Wistar rats exposed to fresh air treated with vehicle into the 4th V. (C) Decrease in mean arterial pressure (MAP, mmHg) and (D) increase in heart rate HR, bpm) in response to sodium nitroprusside (SNP, 50 μg/kg i.v., bolus) in Wistar rats exposed to SSCS treated with vehicle into the 4th V. N = 7. Means ± SDM.
