A. Cumulative concentration response curve to 5-HT generated from baseline, and contracted with prostaglandin F2alpha (PGF2α) in the presence of ketanserin in the normal superior mesenteric resistance artery. B. Cumulative concentration response curve to 5-HT vs. vehicle (H2O) in SMA contracted with U46619 and incubated with ketanserin in SMA. Data points represent mean ± SEM for the number of animals in parentheses.
