[Effects of hypokinesia and hypoxia on the bone static electrogenesis].

It was studied the conformities to law of quasistatic electric potential (QSEP) distribution on the periosteal surface of 64 adult Vistar rats-males fresh exited femur and their changes after dosed hypokinesia and hypoxia influences. The maximal negative sizes of QSEP were incorporated in epiphyseal-metaphyseal departments and minimal--in the central part of bone diaphysis. Conformities to law of QSEP distribution on the periosteal surface fresh exited bone represented the physiology unevenness of metabolic processes intensity in the different bone departments.

[Effect of oxygen deprivation on photosensitivity and thermostability of Drosophila].

There are certain distinctions in firmness to the high temperature and photo sensitiveness between highly and low steady to the hypoxia action of flies. Flies of line Conton-S after preadaptation to hypoxia acquired more firmness to the high temperature. Most of flies in line Uman, who are high-steady to the action of hypoxia, had positive phototaksis.

[The model of hypokinesia in rats and preventing its negative effects].

The special container for modeling of long-term hypokinesia state in rats was developed. Such construction allows us to examine simultaneously hypokinesia and its negative influence correction by gas mixture regulated with different oxygen partial pressure.

[The modeling of experimental osteopenia in rats and development of prophylaxis technology].

An appliance for hind limb unloading in rats and the technology for preventing of inactivity osteopenia have been developed.

[Effect of oxygen deprivation on the development of osteodystrophy caused by the load deficit].

The subject of the study was influence of gas mixture (GGS) with low Po2 on biomechanical properties of femoral and tibial bones in rats after hind-limb unloading. Experiments were performed in two different age groups (three month and six month) rats. It is shown that biomechanical properties of bone tissue in young rats, inhaling atmosferic air, under the influence of 28 days hind-limb unloading deteriorate essentially in comparison with adult rats.
