Fig. 1From: Investigation of the mechanisms of Angelica dahurica root extract-induced vasorelaxation in isolated rat aortic ringsVasorelaxant effect of a 70 % methanol extract of Angelica dahurica root (ADE) on phenylephrine (PE)-precontracted (a, b, and c) or KCl-precontracted (d, e, and f) rat aortic rings. Representative traces show the control group (a and d) and the ADE-treated group (b and e). Control groups were treated with the same volume of Krebs-Henseleit solution without ADE. Values are expressed as mean ± SEM (n = 6–8). *P < 0.05, **P < 0.01 vs. controlBack to article page
