项目摘要

It is extremely important to have an basic idea that our behavior in a daily life on the earth is controlled by the gravity kfrom the cell level to the higher cortical functions as a whole. With using the gravity cue we are controlling our Behavior without any consciousness. This has been done not only by an individual personal experience but also by the longitudinal evolution which has a long historical elapsed time. We have already know many negative aspect of the microgravity to the human body including not only total body but also the simple cell culturing, such as decalcinations from the bone, disadvantage of cumulative exposure for the space radiation, difficulty of early development for the embryo without gravity, and so on. Life science research is just on the way how the gravity plays an important role to the Jiving organ on the earth. Clinostat experiments gives usa lot of knowledge from the usual cell level experiments in our own laboratory without expecting uncertain flight opportunity and expensive budget. There are several advantages to apply the clinostat rotations to the cell level experiments. One is the extended long term cell biological experiments on the earth with less expensive facilities. Another advantage of the clinostat experiment can be easily put into the daily biology research activities without taking into account the special equipments or facilities comparing with the flight experiments. By introducing the clinostat method, we can re-evaluate the gravity importance by doing the ground base experiments and test our hypothesis by flowing same schematic experiments under the real microgravity environments.

我们在地球上的日常生活行为是由重力控制的，从细胞层面到更高级的皮质功能作为一个整体，这一基本观念是极其重要的。通过使用重力线索，我们在没有任何意识的情况下控制了我们的行为。这不仅是由于个人的经验，而且是由于长期的历史演变所造成的。我们已经了解了微重力环境对人体的诸多负面影响，不仅包括对人体的影响，还包括对单纯细胞培养的影响，如骨骼的脱盐、空间辐射的累积暴露、无重力环境下胚胎早期发育的困难等。生命科学的研究正处于重力如何对地球上的生命器官起重要作用的道路上。在我们自己的实验室里，回转器实验给我们提供了大量的知识，从通常的细胞水平的实验中，没有期望不确定的飞行机会和昂贵的预算。在细胞水平实验中应用回转器有几个优点。一种是在地球上用较便宜的设备进行长期细胞生物学实验。与飞行实验相比，回转实验的另一个优点是可以很容易地投入到日常的生物学研究活动中，而不需要考虑特殊的设备或设施。通过引入回转器方法，我们可以通过地面实验重新评估重力的重要性，并在真实的微重力环境下进行相同的原理图实验来验证我们的假设。
