Abstract:
This study was undertaken to investigate the effect of UVB radiation on epidermal melanoctes of C57BIL mouse, The results are summarized as follows : l) The numerical increase of DOPA positive melanocytes following UVB irradiation was due to both of active mitosis of epidermal melanocytes and the conversion of dormant. malanocytes to DOPA-positive melsnocytes. 2) Long term effects of UVB irradiatinn on the epidermal melanocytes suggest the persistent activation of typrosinase in UVB irradiated melanocytes.
