[Experemental modeling of ovary hyperstimulation syndrome in test animals].

The experimental simulation of ovary hyperstimulation syndrome (OHSS) in test murine by administration with several dozes of exogenous gonadotropic hormones has been performed. It has been shown that mouse ovary hormone stimulation leads to manifestation of all OHSS symptoms: ovary swelling and hyperemia, injury of their structure, cystic corpus luteum formation, hemorrhagic follicles, folliculogenesis disturbance, oocyte and embryo morphology injury. The degree of OHSS symptom manifestation depends on hormone doze.

[Electron probe microanalysis of potassium and phosphorus in mouse oocytes and zygotes].

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.
