Figure 1 ET-1, NOx, systolic and diastolic blood pressure and forearm blood flow levels after an intravenous administration of 0.1 U/kg of insulin in 13 CSX patients (circles), in 9 MSX subjects (triangles) and in 13 normal controls (squares). Histograms represent AUCs for the different parameters in CSX patients (filled bars), in MSX subjects (hatched bars) and in normal controls (open bars). Data are means ± SE. Blood Press. = blood pressure; ET-1 = endothelin-1; F. Blood Flow = forearm blood flow; NOx = nitrite/nitrate. #p < 0.05 vs. basal; *p < 0.05 vs. normal controls; p < 0.01 vs. normal controls; p < 0.05 vs. CSX patients.
