In male arteries, maximal relaxation and EC50 values had been also substantially decrease in CSE in comparison with ACh (Table 2).Table 1.

Data show the impact in carotid (A,C) and iliac (B,D) artery segments with endothelium (+E, black symbols) and without endothelium (-E, white symbols). Relaxation is expressed as a percentage of maximal contraction to NA (10-7 M). Data represent the imply SEM; n indicates the number of segments from 4 various rats per group. Statistical analysis was performed by 2-way ANOVA, contemplating concentration and drugs (ACh or CSE) as factors. The p-value was extracted of your interaction term of the ANOVA.
