Fig. 1. Effect of a 4 week experimental diet of doenjang (DJ), cheonggukjang (CGJ), or unfermented raw material mixture (UF) on interferon-γ (IFN-γ) and interleukin (IL)-4 production from splenic T cells stimulated ex vivo compared with standard rodent chow intake (Plain). The IFN-γ IL-4 ratio was calculated by dividing the IFN-γ level with the IL-4 level and then multiplying the result by 100 for each individual culture supernatant. Values are expressed as the mean ± SEM for seven mice per group. ^*p < 0.05 vs. the plain group. ^†p < 0.05 vs. the UF group. ^‡p < 0.05 vs. the CGJ group.
