...Khaled H. Ahmed; Bernd Pelster SUMMARY Exposure of trout hepatocytes to hypertonicity induced a decrease in acridine orange (AO) fluorescence, indicating a corresponding decrease in pH inside the lumen of acidic compartments (pH L). Pre-exposure of cells to the specific V-ATPase inhibitor...

... whereas neither removal of Ca 2+ e nor chelation of Ca 2+ i affected pHi recovery following Na-propionate exposure. Similarly, [Ca 2+ ] i increase induced by hypertonicity appeared to be a consequence of the changes in pHi as Na-free medium as well as cariporide diminished the hypertonicity-induced...
