1 Infusion of stepwise-increasing doses of CCK, ranging from 0.2 to 6.4 pmol/kg X h, induced dose-related increases in plasma CCK (r = 0.99; p less than 0.001), decreases in gallbladder volume (r = 0.99; p less than 0.001), and increases in intraduodenal bilirubin output (r = 0.96; p less than 0.01). Bilirubin cholecystokinin Homo sapiens
2 Infusion of 0.8 pmol/kg X h of CCK, resulting in an increase in plasma CCK of 1.3 +/- 0.5 pmol/L, was the threshold for stimulating gallbladder contraction as assessed by both ultrasonography and measurement of intraduodenal bilirubin output. Bilirubin cholecystokinin Homo sapiens
