Figure 4From: Sidestream cigarette smoke effects on cardiovascular responses in conscious rats: involvement of oxidative stress in the fourth cerebral ventricle (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 ATZ 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 fresh air treated with ATZ into the 4th V. N = 8. Means ± SDM.Back to article page
