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. 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. It was passed by Congress in October, 1919, but was vetoed by President Wilson on October 27.
Much of the credit for this headway can be given to the organization Mothers Against Drunk Drivers (MADD). But now that progress has slowed. Government drinking and driving statistics show that there were about 600 more deaths in 2003 than 1999, when a record-low 16,572 were killed in alcohol-related crashes.
