Effect of OY and fermented OYs on LPS-induced (A) NO and (B) PGE
production. RAW 264.7 cells pretreated with the indicated each concentration of OY or fermented OYs for 30 min before being incubated with LPS (200 ng/mL) for 24 hours. The culture supernatant was analyzed for nitrite production. The data are mean ± SE values of duplicate determinations from three separate experiments. *p < 0.05 and **p < 0.005, compared with LPS-stimulated values.
