Figure 2.

Dynamics of mean ABP changes after intraperitoneal administration of nitroglycerin. Time points in the X axis before the gap show moments of the ABP assessment in the baseline and at the 15th minute after intravenous infusion of either saline or sumatriptan (pre-NTG), whereas after the gap we show moments of the ABP measurements in minutes starting just after NTG administration. The blue boxes correspond to rats of the control group (saline pretreated), the red boxes are for rats of the sumatriptan-pretreated subgroup at a dose of 4 mg/kg, and black boxes are for rats pretreated with sumatriptan at 10 mg/kg. Significance of the differences is not shown, see the text to its assessment.
