赤血球亜鉛量と血清亜鉛量を64例の肺癌患者で測定し, 以下の結果を得た.1)進行肺癌患者では健康成人に比し血清亜鉛量は低下し, 赤血球球亜鉛量は増加した.2)しかし, 炭酸脱水素酵素量に差はなかった.3)進行肺癌患者の赤血球をヘパリン加生食で洗浄すると, 赤血球亜鉛量の約1%の亜鉛の遊離を認めた.4)以上より, 進行肺癌患者では亜鉛の赤血球への集積が見られ, 担癌生体の亜鉛の動態に多大な影響を示すものと考えられた.

Some kinds of spatiotemporal pattern generator systems are expressed by evolution equations. Such evolution equations are composed of many dynamic units which behave from only its local information. This is one example to coordinate many subsystems which observe the system from inside and to generate a global order. This paper shows how to treat these evolution equations and how to apply it to network systems. First, a continuous media system which is expressed by a gradient system in function space is considered. One of the simplest potential functional derives a reaction diffusion equation which decreases the value of potential functional monotonously. The similar result is found in graph space. That is, a reaction diffusion equation on a graph decreases the value of a potential functional monotonously. This means that a network of dynamic units which observe only their connecting units' states can generate a global order in the same way of continuous media. This theory can treat some internal dynamic network system which should coordinate without some kinds of central controllers.
