Table 1.

Values of power (pD2) and maximal relaxant effect (ME) to relaxation induced by acetylcholine and sodium nitroprusside, in aortic rings with (E+) or without (E-) its endothelium from intact (INT), ovariectomized (OVX) and ovariectomized + resveratrol (OVX + RES) groups in both experimental periods. Values are expressed as Mean±SD. Comparisons were made using One-way ANOVA followed by the Newman-Keuls post- hoc test. *p<0.05 compared to INT 60 group; +p<0.05 compared to INT 90 group; # p< 0.05 compared to OVX 90 group
