Figure 1.

Relaxant effect of different concentrations of βES and PRG (1–100 μmol/L) on contractions of endothelium-denuded rat aortic rings induced by KCl (60 mmol/L) (A) or by BAY (0.1 μmol/L after KCl 10 mmol/L) (B). Each point represents the mean value and the vertical lines indicate SEM of at least 5 experiments. Control experiments were performed using with ethanol, the vehicle used to dissolve the hormones. ^bP<0.05 versus control. ^fP<0.01 βES versus PRG. One-way ANOVA followed by with Tukey post hoc test.
