Integrated regulation in response to simulated weightlessness.

Hang tian yi xue yu yi xue gong cheng = Space medicine & medical engineering, 1997
To investigate physiological effects of tail suspension, Ca2+ concentration, immune factors, erythrocyte rheological properties, and growth hormone were determined in rats suspended for 15 and 30 d. The results showed that inhibitory changes of both local factors (proteins secreted by bone cell, Ca(2+)-ATPase in sarcoplasmic reticium) and integrated ...

[The effect of weightlessness and simulated weightlessness on the expression of genes].

Hang tian yi xue yu yi xue gong cheng = Space medicine & medical engineering, 2003
The research results of the relationship between gene expression and weightlessness or simulated weightlessness were studied. The influence of weight on the expression of genes in central nervous system were summarized in three aspects. It can be concluded that the expression of genes in central nervous system were precisely regulated by weight. It was

Neuromuscular adaptation to actual and simulated weightlessness.

Advances in space biology and medicine, 1995
The chronic "unloading" of the neuromuscular system during spaceflight has detrimental functional and morphological effects. Changes in the metabolic and mechanical properties of the musculature can be attributed largely to the loss of muscle protein and the alteration in the relative proportion of the proteins in skeletal muscle, particularly in the ...

Bone changes during simulated weightlessness in rats.

Indian journal of physiology and pharmacology, 2000
Weightless environment due to prolonged Space mission results in decreased mineralisation of the weight bearing bones. Hind limb unweighting (HU) in rats by tail suspension was used to simulate the effect of weightlessness on tibia. Adult male albino rats were divided into two groups as (i) Control (CON, n = 12) and (ii) HU for 15 days (HU, n = 18 ...

Erythrocyte deformation in simulated weightless human and rabbits.

Journal of gravitational physiology : a journal of the International Society for Gravitational Physiology, 1999
Effect and mechanism of simulated weightlessness (SWL) in humans and rabbits erythrocyte deformation were studied. Erythrocyte deformation and membrane fluidity in humans and rabbits, and erythrocyte morphology and hemorreology indices in control and HDT rabbits were measured. The results were a decrease in erythrocyte deformation and membrane fluidity
