[Trace elements maintaining the vital functions].

In a healthy condition, trace elements constituting the living body are regulated and maintained their balance of each other and their range of physiological optimum concentration in order to maintain the normal vital functions. When the optimum conditions of their balance and their homeostasis, however, are broken down by deficiency or excess of certain trace element, an excess accumulation or deficiency of specified element is induced and it follows that peculiar disease is caused according to function of each specified element. Generally, the disturbance of major elements such as O, C, H, N, Ca, P will induce a nutrition lesion and electrolytic abnormality, and the disturbance of 10 trace elements such as Fe, F, Si, Zn, Sr, Rb, Br, Pb, Mn, Cu being at ppm order and 14 ultra-trace elements such as Al, Cd, Sn, Ba, Hg, Se, I, Mo, Ni, B, Cr, As, Co, V being at ppb order will give rise to functional disorder of enzyme and physiological active substance in living body.
