Table 1 Basal and peak plasma values of cholecystokinin (CCK) and oxytocin

From: Oxytocin and cholecystokinin secretion in women with colectomy

  CCK (pmol/l) N = 11 Oxytocin (pmol/l) N = 11
Controls   
Basal 0.7 ± 0.1 1.3 ± 0.1
Peak 0.9 ± 0.1 2.8 ± 0.4***
Patients   
Basal 1.0 ± 0.2 1.6 ± 0.2
Peak 1.8 ± 0.3**+ 3.3 ± 0.5***
  1. Values are expressed as mean value ± standard error of the mean (SEM). Comparisons are made within groups; ** = p < 0.01, *** = p < 0.001, and between groups; + = p < 0.05. Wilcoxon signed rank test. The basal value is the mean of the two fasting values. The peak value is the mean of the highest concentration in every subject after the injection.
