Curcumin reduces VIS related oxidative stress HN cells were pre-incubated with dihydrorhodamine and curcumin. Thereafter the cultures were irradiated with VIS for 5min (black bars) or were kept light protected (white bars). Fluorescence measured after 60 minutes is shown. The values of the un-irradiated controls were set to 100%. The data displayed are representative of three experiments performed with comparable results. Average absorbance values (mean ± SD) from sextuplicate replicates per experimental condition were calculated. * p ≤ 0.05 versus the irradiated control.
