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.
âNo temperance in itâ¦â: Woodrow Wilson & Prohibition Because Prohibition began in Wilsonâs administration it is often assumed that he supported it. In fact, Wilson vetoed the infamous Volstead Act which enforced Prohibition and he opposed a federal law enforcing what he thought was a personal moral issue.he 1916 election was a watershed moment for the prohibition campaign. Both Democratic incumbent Woodrow Wilson and Republican candidate Charles Evans Hughes ignored the Prohibition issue, as did both party's political platforms.
