During a HIDA Scan a scanner monitors the radioisotope that was initially injected. When (CCK) cholecystokinin, a hormone that's normally released by the body after a meal, is injected, the contraction of the gallbladder is identified on the scan. Reduced contraction (which often produces pain) may mean anything from actual gallbladder disease/dysfunction, to inflammation or scarring.
United States History. Volstead Act. Andrew J. Volstead, Republican representative from Minnesota, was the driving force behind the National Prohibition Act (popularly the Volstead Act), written to provide for the enforcement of the recently ratified 18th Amendment.
Prohibition was a tool that the white South could use to keep down the black population. In fact, they used Prohibition to keep liquor away from black people but not from white people. So you could find a number of ways that people could come into whatever issue they wanted to use and use Prohibition as their tool. The clearest one, probably, was women's suffrage.
