Functional load test and re-adapt to the role of factors that hemodynamic responses under
, PEP / LVET increased. These changes lasted for 1 month. However, after 84 days flying over 28 days and 56 days to adapt to post-flight easier, and that all change is a functional rather than pathological. Of the cardiovascular system that is well adapted micro-gravity, changes in heart size and function of limited space is unlikely to be a factor. Weightlessness, fluids shift from the lower body to upper body, upper body after landing from the transfer to the lower body, this fluid redistribution is 3 to 6 hours of continuous dynamic process, l Skylab astronauts in the rinse arm measured the venous pressure, confirmed this point. After landing lh, CVP higher than the flight, this is due to extravascular fluid shift rapidly to the results of intravascular red cell hematocrit dropped 5 fine proof of this view. After 12h, CVP returned to initial levels. Blood pressure and between organisms hydration asymmetry disappeared. The reaction was short flight experiments had to be carefully applied to the long flight. Return to Earth, circulating blood volume and extracellular fluid remained normal orthostatic tolerance decreased. Gazenko other view is that according to this state of lower limb disorders, where excessive blood storage, caused by reduced venous return. LBNP experiments confirmed this point. Even in the - 25, when a 35mmHgLBNP tachycardia and pulse pressure significantly decreased. 2 to 4 days after landing in the active and passive experiments have similar hemodynamic changes. Weight loss or return to Earth has entered an adaptive stress acting on the body. Short-term adaptive stress does not cause pathological changes in the load, but if the long role in the body, may cause pathological changes become adapted disease. In our view, adaptive load of significant change after a hard as a normal adaptive changes, because they are adaptive dysfunction and loss of working capacity boundary line, so we had a bad adaptation. Therefore, in order to determine the safety of astronauts during weightlessness limits, and flight after flight to ensure the health,[link widoczny dla zalogowanych], in order to study the mechanism of adaptive response and improvement of protective measures, the changes caused by weightlessness etiology research is very necessary. SHEN Xian-yun translated Hypokinesiaandweightlessness; a fi {Fu. I,,,. Health hairpin l j} F1 show I; City ClinicalandPhysiologicAspectsP87 ~ 94 write-female environment, a microbial-based model of controlled ecological life support system 'Melissa \One option is based on a microbial ecosystem, as the development of future lunar base such as human space missions, the hub of biological life support system,[link widoczny dla zalogowanych], a simplified model, is also a small research tool. Melissa aims light as an energy source,[link widoczny dla zalogowanych], to promote biological photosynthesis, from the waste (stool, urine),[link widoczny dla zalogowanych], CO and minerals in the recovery of edible biomass. It consists of the European spacecraft thermal and environmental control at the host, the European Space Agency (ESA ) Overall, in collaboration with the voluntary collaborators jointly developed in close cooperation. The four-room plan selection ecosystems, and the material loop around food production and the formation of oxygen regeneration of the center closed circulation, the central task of the spiral bacteria from the blue algae to complete. spirulina nitrate needed, CO: Room and minerals produced by other microorganisms. For this project, they first conducted a survey of literature related to research,[link widoczny dla zalogowanych], to check the validity of the basic programs, and theoretically studied the efficiency, safety, quality and biomass is a process to another process, toxic effects. and then the experimental study, first, Clostridium, red bacteria, nitrifying bacteria and pure culture of Spirulina and other experimental study and later in the laboratory and in the Chinese Long March rocket launched the satellite, the health differences were Euglenophyta length (intake of oxygen and release CO:) and Photoautotrophic long cyanobacteria (release oxygen uptake of CO:) of closed-circuit gas exchange experiments, the culture medium were installed in a small dialysis tube, so that it can carry out gas exchange with the surrounding. In addition, the laboratory also conducted O: consumption of those (fish) and producers (Spirulina) between similar gas exchange experiments and experiments under laboratory conditions for a month straight. At the same time, also conducted a mass balance of the system and its mathematical model, and Melissa's physical examination to understand the degree and the closed loop process control The main technical difficulties to expect. 6
