To find compounds of immunomodulating and anti-allergic function, effects of protein-bound polysaccharides extracted from Phellinus igniarius (Pl), Fomitella fraxinea (FF) and Agrocybe cylindracea (AC) on hemagglutinin titer (HA), hemolysin titer (HY), plaque forming cell (PFC), rosette forming cell (RFC) and phagocytosis were investigated in BALE/C mice. The oral administration of the protein-bound polysaccharides of PI, FF and AC for 10 days resulted in the enhanced phagocytic activity of peritoneal exudate cells (PEC), spleen cells (SC) and blood lymphocyte cells (BLC).Moreover, PI showed the activating effect on the phagocytosis of PEC and AC in SC. In the experiment of PFC and RFC, the results of the experimental group which was given each samples as compared to the control group, showed the enhanced level of activity such as PI 130%, FF 90% and AC 70%. Generally, HY and HA showed from ten to hundred times of level in each sample groups, as compared to the control group.
