Figure 9.

Effects of pretreatments with either atropine, indomethacin, ACh, or L-NAME on the vasorelaxant effect produced by ME (A) or C3G (B) in the RIAR system. The abscissae correspond to an increased concentration. Ordinates show changes in the vasorelaxant effect caused by ME (A) or C3G (B) with several pretreatments, with a sample size of eight for each treatment. The symbols represent the mean ± SEM of eight experiments. ✱ shows a significant difference between control and ME + L-NAME values (A) and between control and C3G + L-NAME values (B). p < 0.05 ANOVA post hoc Dunnett’s test.
