Abstract: The experiment was conducted to study the effect of polysaccharide from atractylodis macrocephalae (PAM) on proliferation of lymphocytes and signaling related molecules like NO, cAMP and cGMP in peripheral blood of piglet. Effects of PAM on proliferation of peripheral blood lymphocytes of piglet were tested by MTT assay. The production of IFN-γ in supernatant were determined by ELISA; the content of cAMP and cGMP were tested by RIA. The concentration of NO was tested by deoxidization assay. The results showed that PAM insignificantly increased proliferation of lymphocytes and the contents of NO, cAMP and IFN-γ in similar dose dependent manner. In conclusion, PAM might perform its immunoregulation functions via signal transduction system in immunocytes by activating immunocytes to release NO and cAMP/cGMP and raise IFN-γ.

Key words: PAM, NO, cGA, P cGMP, IFN-γ, Immunomodulation
