Abstract
Objectives : The purpose of this study is to investigate effects of Scutellariae Radix water extract on hydrogen peroxide production in LPS-induced RAW 264.7 mouse macrophages.
Methods : Scutellariae Radix produced from South Korea (SK) and Scutellariae Radix produced from China (SC) were extracted by hot water. Effects of SK and SC on hydrogen peroxide production in LPS-induced RAW 264.7 were measured by dihydrorhodamine 123 assay after 20, 24, 28, 44, 48, and 52 h incubation at the concentrations of 10, 25, 50, and 100 ug/mL.
Results : SK significantly increased hydrogen peroxide production in LPS-induced RAW 264.7 cells for 20, 24, 28, 44, 48, and 52 h incubation at the concentrations of 10, 25, 50, and 100 ug/mL (P < 0.05). But SC did not represent any significant effect on hydrogen peroxide production in LPS-induced RAW 264.7 cells.
Conclusions : These results suggest that Scutellariae Radix, especially produced from South Korea, has the immune-enhancing property related with its increasement of bacteriocidal hydrogen peroxide production in LPS-induced macrophages.
