Abstract

Paramecium tetraurelia cultured aboard Salyut 6 have shown in increase in cell growth rate, cell volume, water content and changes in electrolyte content. Additional experiments, carried out in balloon flight and on earth, showed that the stimulating effect observed on cell proliferation is related to exposure to cosmic rays. Other changes seem to be due to a direct effect of microgravity on cell. Mechanism of gravity action on cell is discussed.

摘要

在“礼炮6号”上培养的四膜虫显示出细胞生长速率、细胞体积、含水量增加以及电解质含量变化。在气球飞行和地球上进行的其他实验表明，观察到的对细胞增殖的刺激作用与暴露于宇宙射线有关。其他变化似乎是由于微重力对细胞的直接作用。本文讨论了重力对细胞作用的机制。
