title: Distribution and form of uranium-containing deposits in chickens treated with uranyl nitrate.
abstract: The kidneys of chicks treated with uranyl nitrate were examined by electron microscopy. Most deposits of electron-dense material containing uranium were found in the lumina of distal tubules and collecting ducts of kidneys collected 12-24 hours post-treatment. Some deposits were present in extracellular spaces between adjacent cells. Only occasionally were deposits found intracellularly where they were associated with localized cellular degeneration. A generalized cellular degeneration over the whole kidney was seen 72-96 hours post-treatment, but this was not directly associated with the deposits of electron-dense material.
