Figure 2: Concentration-response curves for resveratrol were obtained in preparations precontracted with phenylephrine and K+-rich (100 mM K+) Krebs-Ringer bicarbonate solution. Endothelium was intact. Responses are expressed as a percentage of the maximum possible relaxation, i.e., the return of tension to the pre-phenylephrine level. Each point represents the mean SEM (n=10).
