title: [Reorganization of the Golgi apparatus of epithelial cells in the frog bladder in stimulation of water transport by antidiuretic hormone].
abstract: Ultrastructural changes of Golgi apparatus of frog urinary granular cells at antidiuretic hormone (ADH) stimulation of water transport were studied. During a short-time ADH action (5 min) the fragmentation of the complex on single dictyosomes and dilution of certain cisternae is discovered. A conclusion is made that the granular cell giant vacuoles may originate from the Golgi cisternae. It is suggested that the microtubules may be involved in the translocation of dictyosomes and migration of formed vacuoles. The quantity of microtubules increases during ADH action very significantly. Moreover, the involvement of the Golgi apparatus is shown in the maintenance of the cell membrane balance due to budding of tubular structures from transcisternae and shuttling between luminal and vacuolar membranes.
