초록

This study was designed to investigate the protective effect of the combination of fucoidan and lutein against AAPH-induced oxidative stress in THP-1 cells. The combination of fucoidan and lutein existed significant antioxidant effect on AAPH-damaged THP-1 cells by using lipid peroxidation and cellular antioxidant capacity assay. Fucoidan(1㎍/㎖) and lutein(10㎍/㎖) did not affect at all the viability of THP-1 cells, but protected the AAPH-damage of THP-1 cells at the same concentration. The viability of THP-1 cells was 0% with 1 mM AAPH alone, the protective effect of fucoidan(1㎍/㎖) and lutein(10㎍/㎖) was 37% and 36%, respectively. The combination of fucoidan(1㎍/㎖) and lutein(10㎍/㎖) exhibited significant inhibitory effect of lipid peroxidation using TBARS assay and cellular antioxidant capacity using DCFH-DA assay. In lipid peroxidation, the TBARS value of 1mM AAPH alone was 0.8±0.03nM MDA, its of the combination of fucoidan(1㎍/㎖) and lutein(10㎍/㎖) was 0.2±0.05nM MDA. In cellular antioxidant capacity, the combination of fucoidan(1㎍/㎖) and lutein(10㎍/㎖) exhibited significant cellular antioxidant capacity of 76%, whereas quercetin(10μM) as positive control exhibited the cellular antioxidant capacity of 32%. These results indicate that the cotreatment of fucoidan and lutein protects against AAPH-induced THP-1 cell damage by inhibiting lipid peroxidation, increasing cellular antioxidant capacity.
