Lutein protects human lens epithelial cells from phototoxicity of fullerol. The cells were incubated with 20 µM lutein in Minimum Essential Medium (MEM)/DMSO (99:1) for 2 h and with 15µM fullerol in MEM/DMSO (99:1) for the next 16 h. Then the cells were washed and overlaid with HBSS and exposed to UVA for 10 min. After irradiation, the cells were incubated overnight in MEM/FBS (8:2). Metabolic activity (A) and lactate dehydrogenase release (B) from the cells were determined with MTS and LDH assays, respectively. Values are expressed as mean ± SE (n=4). * p<0.01, comparing metabolic activity or LDH release in cells incubated with lutein and fullerol vs. cells incubated only with fullerol both in the “dark” and “UVA exposed” group.
