Figure 3: Attenuating effect of Rd on the reactive oxygen species levels in HaCaT keratinocytes under ultraviolet-B irradiation. HaCaT cells were pretreated with Rd (0, 5, 12 and 30 μM) for 30 min prior to the irradiation. Reactive oxygen species levels were represented as 2',7'-dichlorodihydrofluorescein fluorescence arbitrary unit expressed as % of the non-treated control and each bar shows the mean ± standard deviation of the three independent experiments repeated in triplicate. **P < 0.01 versus ultraviolet-B irradiation alone (at column width)
