论生物体内的生物元素图谱

给出了生物元素的定义，讨论了人体内存在的生物元素的由来及功能；系统地总结了 s区和p区主族元素、d区过渡元素和f区稀土元素对四膜虫真核细胞生长分裂的促进或营养作用及毒性抑制的影响，得到一定的规律性。提出生物体内存在着“生物元素平衡图谱”，它于三维元素周期表空间内展现出来，是反映生物与地球表面环境之间物质交换、能量交换达到动态平衡的标志。这样，三维元素周期表不仅揭示各元素及化合物的物理 、化学性质，看来也能在一定程度上预示它们的生物学性质。

On the Biological Element Spectrum in Organism

A definition of biological essential element was proposed. Their origin and function in human body were discussed. An excellent strain S1 of Tetrahymena, a kind of ciliates, has been used in this study to observe both stimulation or nutritious and toxic inhibition effects of elements located in s block, p block, d block, and f block in the periodic table, some regularity between the biological effects of these elements and their positions in the periodic table has been obtained. It is shown that a “spectrum of biological element equilibrium”, which exists in organism, can be exhibited in the periodic table designed in the three-dimensional space, if the abundance of biological elements or/and their bioavailability is used as the third z axis, a vertical line to the plane of the periodic table, and then the biological element spectrum shows that the exchanges of matter and energy between organism and surface environment of the earth have been reached the dynamic equilibrium state. It seems that not only physical and chemical properties of different elements and their compounds can be shown in the developed periodic table, but also their biological properties to a certain extent.
