Main Projects

1.  Effect of ultraviolet exposure on cultured mammalian cells
 The major effect of ultraviolet is known to be on nuclear events such as DNA damage. On the other hand, there is accumulating evidences that UV affects biomembrane functions. We investigate the effect of UVA and UVB on biomembrane functions and apoptosis in cultured mammalian cells.

2. Effect of ionizing radiation on macrophages, and radiation hormesis
 Low-doses of ionizing radiation have been known to enhance the immune functions. Macrophages have not been considered to be target cells by low-dose irradiation because of their radioresistance, but play an important role in the immune responses. We investigate the effect of low-dose in vivo and in vitro irradiation on macrophages.

3. Combined effects of environmental contaminants and ultraviolet
 We have misgiving about that UV is increasing with the destruction of ozone layer. Chemical substances such as surfactants and polymer in environment must be affected by UV. We investigate the combined effects of surfactants and UV on cultured mammalian cells.

4. Synthesis and degradation of polymers in reversed micelles
 We study the synthesis of biological polymers such as polyA and the degradation of chemical polymers such as plastics in reversed micelles.
