Abstract

The effect of increasing intravenous doses of synthetic salmon calcitonin (0.0044, 0.0088, 0.0175, and 0.0350 iu/kg per min) versus placebo on the fasted gall-bladder volume was assessed in seven normal subjects according to a double-blind study protocol. In addition, the action of calcitonin on meal-induced gall-bladder emptying was examined. Gall-bladder volumes were measured by means of real-time ultrasonography. Calcitonin evoked a dose-dependent relaxation of the fasted gall-bladder. A statistically significant increase of the fasted gall-bladder volume was observed with 0.0175 (23.4 +/- 5.5 cm3 placebo versus 33.9 +/- 7.7 cm3 calcitonin, P less than 0.001) and 0.0350 (21.4 +/- 4.6 cm3 placebo versus 36.1 +/- 8.4 cm3 calcitonin, P less than 0.01) iu/kg per min calcitonin, whereas a mean increase of the gall-bladder volume amounted to 32.1% and 46.5%, respectively. A significant delay of the gall-bladder emptying after calcitonin was reflected by a decrease of the ejection fraction: 23.2 +/- 8.3% calcitonin versus 57.8 +/- 6.9% placebo (P less than 0.02) at 20 min, and 40.5 +/- 8.8% calcitonin versus 67.2 +/- 3.8% placebo (P less than 0.02) at 30 min after the test meal. Calcitonin is concluded to have a potent relaxing eff...Continue Reading
