Effect of eugenol (100 µM), linalool (100 µM) and carvone (100 µM) on the contraction induced by PE in endothelium-intact thoracic aortic rings. Results are presented as the mean ± S.E.M. (n=5); **P≤0.05 compares a significant variation in contractions shown by these molecules in both unexposed and exposed ring segments of the rat aorta (unpaired Students t-test); *P≤0.05 shows significant difference of PE-induced contractions shown by eugenol, linalool and carvone versus control (ANOVA) followed by Duncan's multiple range test; n: number of tissues.
