The effect of carbachol on the gallbladder in Black and White subjects.
The effect of carbachol on the gallbladder was assessed in 24 White and 24 Black volunteers. The results suggest that in Blacks the gallbladder empties to a signigicantly greater degree than it does in Whites after administration of carbachol. This fact may account, in part, for the lower incidence of cholelithiasis in Black populations. No difference in gallbladder contractility was found between men and women nor did gallbladder response appear to be influence by hormonal factors.
