By means of two-wavelength ultraviolet cytospectrophotometry a marked RNA accumulation was revealed in the cytoplasm of motoneurons of lumbar intumescence of the rat spinal cord after 3-week-long hypoxia or hypokinesia as well as their combination. In the neuroglial cells adjacent to these
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
The investigations were designed to study the long-term effect of hypoxia, hypokinesia and of combined hypokinesia and hypoxia on the skeletal muscle in the rat. In the muscles of the hypoxic and hypokinetic animals serious degenerative changes were found and the fibre-type ratio was altered. In the
This investigation was designed to study the long term effect of combined hypokinesia and hypoxia on the skeletal muscle. In the muscles of the hypoxic and hypokinetic animals, serious degenerative changes were found and the fibre type ratio was alterated. The malate dehydrogenase activity was
The hypokinesia initiated on the distrophic changes in the rats' femur bones was studied. The interrupted normobaric hypoxia destructive inhibited possibility in the bone tissue was also investigated. It was shown that inspiration the gaz mixture (nitrogen and oxygen (Po2 = 100-110 mm Hg) normalizes
On 62 white male rats at hypokinesia lasting for 7-60 days, motoneurons and neural cells of the lumbar sensitive ganglia have been studied at the level of L2--L4. Certain changes in the spinal ganglia have been neurohistologically revealed beginning from the 30th day of the experiment. In most of
Long-term locomotive regimens of moderate intensity change the spontaneous locomotive activity (SLA). Hypokinesia leads to the SLA reduction whereas additional physical loads cause its increment, changing hypophyseal-adrenal system reactivity, too. Tolerance to hypoxic hypoxia under locomotive
