Effects of hypo- and hyperosmotic shocks on the volume and ions content of Carcnus maenas isolated axons

Invertebrate Cell Volume Control Mechanisms: A Coordinated Use of Intracellular Amino Acids and Inorganic Ions as Osmotic Solute

“…For example, isolated Callinectes axons swell during exposure to a hypoosmotic stress and then return toward the initial volume utilizing a mechanism that requires Ca 2+ and ATP (Gerard, 1975). Axons from other euryhaline Crustacea also show similar patterns of volume changes (Gilles, 1973;Kevers et al, 1979a). Although electrical recordings have not accompanied the above studies, neuronal cell volume regulation is accompanied by an adaptation in the electrical properties of the cells.…”

The effect of β-alanine on the concentration of taurine and other free amino acids during osmotic stress ofMytilus galloprovincialis

“…The mechanisms involved in the osmotic balance depend on the type and the intensity of the stress. In fact, in the case of hyposmotic stress cell volume can increase as a consequence of the water uptake, which is parallel to the extrusion of cellular osmotically active solute (Bricteux-Gregoire et al 1964;Gilles, 1978;Gilles & Pequeux, 1981: Kevers, Pequeux & Gilles, 1979Mangum et al 1976;Oglesby, 1981;Pierce & Greenberg, 1976;Costa, Pierce & Warren, 1980;Pierce, 1982).…”

“…On the other hand, in hyperosmotic stress a loss of water from the cell and an increase in the intracellular concentration of the osmotically active solutes occurs (Gilles, 1977(Gilles, ,1978Kevers et al 1979;Otto & Pierce, 1981;Pierce & Greenberg, 1973;Rorive & Gilles, 1979).…”
