Involvement of Potassium Channels in Vasorelaxant Effect Induced by Valeriana prionophylla Standl. in Rat Mesenteric Artery
Figure 6
Effect of VPR on MAP and HR in nonanesthetized rats. (a) Representative tracing showed the hypotension induced by addition of VPR (20 mg/kg). (b) Changes in mean arterial pressure (MAP, mmHg). (c) Changes in heart rate (HR, bpm) induced by the acute administration of increasing doses of VPR (mg/kg, i.v). Values are expressed by mean ± SEM; .
