In fasting human serum, cholecystokinin (CCK) is not the principal substance which causes in vitro rabbit gallbladder contraction. Removal of CCK by affinity chromatography from fasting sera from 8 healthy adults reduced bioactivity only by 18 +/- 4% (SEM). Unlike CCK, the bioactivity of serum was enhanced by 30 to 57% rather than destroyed by pronase and… CONTINUE READING
