Abstract:
Objective To study the anti-tumor activity of Phellinus linteus(PL) and its immunomodulational effects.Methods Solid tumor was induced by injecting HepA,MFC,S_(180) cells(3?10~6cells/animal) subcutaneously to the right anterior limb in mice.The tumor weight,thymus weight and spleen weight were measured after mice were executed.The effects of PL on lymphocyte proliferation,mitogen-induced proliferatoin of ICR mouse splenocytes were measured by MTT.Meanwhile,lymphocytes were prepared as described above.SRBC(10%,0.2 mL) was injected to abdominal cavity to elevate the level of antibody production by B cells.Spleen cells suspension(1?10~7?mL~(-1)) was used as the effect cells and L_(929) cells was used as the target cells.L_(929) cells engulfing neutral red determined the cytotoxic activity of NK.Simultaneously,phagocytosis of mice was detected using the method that macrophages engulfed neutral red.The effect of PL on the production of antibody was studied,the lymphocytes from mice were prepared as described above.Results The high-dose(2.0 g?kg~(-1)) and mid-dose(1.0 g?kg~(-1)) of PL could significantly inhibit the growth of HepA,MFC and S_(180)tumor,the inhibitory rates were 38.19% and 37.15%,32.46% and 30.91%,36.0% and 34.16%,respectively(P
