This study examined the effects of GATA-3-dependent Th2 cells and IgE inhibition by using PM-E and PM-70M isolated from Sasao. It was analyzed that the 70 % methanol layer contained adsorbed chromatograms of the fraction of sodium hypochlorite that inhibited GATA-3 transcription factor activity. As a result, PM-70 %MFL fraction seems to have an antiallergic effect by inhibiting GATA-3 which regulates Th2 cytokine. PM-30A, PM-70A, and PM-30A layers by inhibiting IgE secretion in B cells by co-culturing the fractions with anti-CD40/rmIL-6 and TNF-${\alpha}$ mRNA and IgE were not different from control. However, expression of IL-6 and TNF-${\alpha}$ mRNA was $0.69{\pm}0.058$ (p<0.001) and $0.72{\pm}0.58$ (p<0.05), respectively. The amount of IgE secretion was $94.6{\pm}16.0$, which was significantly decreased by 45.6% (p<0.01) compared with the control group. This study suggests that the PM-70% MFL layer in the fraction of Sasao contains the components that inhibit the differentiation and activity of B cells.
