Summary graphs showing significant differences in pressure-induced SMC [Ca2+]i responses and associated myogenic tone of uterine arteries from nonpregnant versus pregnant horns of late pregnant rats. No difference was found in the basal levels of SMC [Ca2+]i in arteries from nonpregnant versus pregnant horns at 10 mm Hg. Myogenic tone is expressed as a percentage of the diameter measured in the presence of 100 μmol/L papaverine and 10 μmol/L diltiazem (Dmax). *Significantly different at P < .05 (two-way repeated measures ANOVA); numbers in parentheses indicate the number of arteries tested.
