Far infrared ray (4-14 μm) emitting materials or products including platinum electro-magnetic wave fiber have recently been widely used for improving various disorders, promoting health and beauty, and preserving food freshness etc. This mechanisms is to decrease the size of water structure (cluster) by cleaving the bonds of H2O in polymer, which leads to the better penetration of water into the cell mem-brane with resultant increase in intracellular calcium concentration [Ca2+] i and potentiation of cell activa-tion. In this connection, we examined the effect of this platinum colloid fiber on [Ca2+] i, chemotaxis, phagocytosis and O-2 generation of normal human neutrophils, and blastogenesis of lymphocytes. Its effect on lipid peroxidation from unsaturated fatty acids was also tested. The test tubes containing neutro-phils and lymphocytes, and docosahexaenoic acid were surrounded and contacted with platinum colloid fiber.
The result revealed that platinum fiber significantly enhanced [Ca2+] i, chemotaxis, phagocytosis and O-2 generation by normal neutrophils, and the blastogenesis of the lymphocytes. Lipid peroxidation was also markedly inhibited. Our study suggests that platinum colloid fiber promotes our health by potentiating the cell function.
