It is well-known that the liquid component of blood can be an important marker for assessing health conditions. But the cellular components of blood also convey to us various other information. This paper explains the knowledge obtained from the author's experiments examining blood cells, and how this knowledge elucidates regulational functions of aging. For example, from the facts that: 1. the life span of germfree mice was longer than that of conventional mice, 2. the life span of normal mice with restricted diet(60%)was longer than that of non-restricted normal mice, and that, as the author's experiment revealed, 3. the length and life of their small intestinal epithelial cells were also greater than those of each control group, the author surmises that small intestinal epithelial cells might be a marker for detecting the situation of the regulation of aging. Experiments designed to measure the life span of red blood cells lead the author to find that the number of T-cells in mice on restricted diets increased and immune responses were accelerated. And finally, the author explains experiments examining platelets of laboratory mice to determine the function of EPA(Eicosapentaenoic acid)in the blood coagulation system.
