Effect of Polysaccharide from Ilex kudingcha C.J. Tseng on the Immune Regulation and Antioxidation of Spleen Lymphocytes from Mice

To investigate the immune regulation and antioxidation effects of polysaccharide from Ilex kudingcha C.J. Tseng on mouse spleen lymphocytes in vitro. The proliferation, antioxidant capacity (SOD, T-AOC, GSH-Px and CAT) activity and malonic dialdehyde (MDA) content, as well as the secretion of cytokines (TNF-α, IFN-γ and IL-1β) were detected after treating with polysaccharide from Ilex kudingcha C.J. Tseng. The results showed that polysaccharide from Ilex kudingcha C.J. Tseng could promote the proliferation of spleen lymphocytes dose-dependently. Compared to the OD value of control group (0.31), the OD values at the concentration of 80 and 160 μg/mL were increased significantly (P
