The relationship between UVB screening and cytoprotection by microcorpuscular ZnO or ascorbate aganist DNA photodamage and membreane injuries in keratinocytes by oxidative stress

摘要

Decreased cell viability and increased formation of cyclobutane-type pyrimidine dimers (CPDs) is DNA is UVB-irradiated keratinocytes were shown to be appreciably restored by the addition of w/o emulsion of microcorpuscular zine oxide (mcZnO) with a corpuscle diameter of 0.15 #mu#m.
