title: [Electron probe microanalysis of potassium and phosphorus in mouse oocytes and zygotes].
abstract: Intracellular concentrations of potassium and phosphorus were determined by Electron Probe Microanalysis in mouse mature oocytes and zygotes. The oocytes were characterized by insignificant variations in the concentrations of these elements in the cytoplasm: 60 +/- 4 and 103 +/- 6 mM, respectively. In zygotes, on the contrary, significant variations were observed: 64 +/- 16 and 84 +/- 14 mM, respectively. Changes in the potassium homeostasis during the first cell cycle have been discussed.
