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.
It was that driving force that first gave me the idea to put licensed characters on children's dinnerware as a way to give kids something to look forward to at mealtime. And it's that same driving force that has helped Zak Designs grow into the global leader it is today.
