FIGURE 4.
(A) Concentration-response curve of phenylephrine (10−9 M–10−5 M), (B) concentration-response curve of carbachol (10−9 M–10−4 M), and (C) concentration-response curve of sodium nitroprusside (SNP) (10−9 M–10−6 M) in isolated rat aorta rings from animals two weeks post-treatment with saline (sequelae saline, white circles) or vincristine (sequelae vincristine, black circles). Values are expressed as mean ± SEM, n = 9–12 preparations per experimental group. A two-way ANOVA followed by the Bonferroni test was used for statistical analysis.
