The Given

The paper presents the results of the author's research aimed at finding new methods of vibrodynamic sealing of sandy soils foundation by using the energy of water flow. The data of water flow parameters providing the given speed of its movement without the significant carryover of sand particles based on the theoretical studies, as well as the laboratory studies of sandy soil dumping into a water flow (with an average horizontal velocity of about 10-15 cm/s) on a specially designed hydraulic tray are described in the paper.

Cytoskeletal System

The amphibian urinary bladder has been used as a ‘model’ system for studies of the mechanism of action of antidiuretic hormone (ADH) in stimulating transepithelial water flow. The increase in water permeability is accompanied by morphological changes that include the stimulation of apical microvilli, mobilization of microtubules and microfilaments and vesicular membrane fusion events . It has been shown that alterations in the cytosolic calcium concentrations can inhibit ADH transmembrane water flow and induce alterations in the epithelial cell cytomorphology, including the cytoskeletal system . Recently, the subapical granules of the granular cell in the amphibian urinary bladder have been shown to contain high concentrations of calcium, and it was suggested that these cytoplasmic constituents may act as calcium storage sites for intracellular calcium homeostasis. The present study utilizes the calcium antagonist, verapamil, to examine the effect of calcium deprivation on the cytomorphological features of epithelial cells from amphibian urinary bladder, with particular emphasis on subapical granule and microfilament distribution.
