Figure 3 Left ventricular tissues of patients were divided into two groups (n = 12 each) according to the median values of their NOS II-(iNOS) activity (individual data are depicted in Figure 2). (Left panel) Mean values (± SEM) for NOS II-(iNOS) activities of these two groups (statistically significant by definition). (Middle panel) Force of contraction at baseline (B) and following isoproterenol (ISO) for both groups, both absolute values and percent increase with isoproterenol are depicted. (Right panel) ß-Adrenoceptor density (Bmax) of both groups. White bars = patients with iNOS-activity > 3,120; solid bars = patients with iNOS-activity < 3,120.
