EFFECT OF BEE POLLEN ON SERUM IGM AND IGG CONCEN TRATION IN NORMAL AND IMMUNODEPRESSED MICE / 中国药理学通报

ABSTRACT

The effect of bee pollen on serum IgM and IgG concentration was investigated in normal and immunodepressed mice.The levels of serum IgM and IgG in normal NIH mice were 0.80? 0.07mg/ml ( X ? SD ) and 11. 42 ?2. 31 mg/ml respectively. The concentration of IgM and IgG were all markedly lowered in immunodepres-ssed mice induced by cyclophosphamide 100 mg/kg/d sc for 4d,hydro-cortison 100 mg/kg/d sc for 6d,60Co ?-irradiation 600 rads and S-180 tumor-bearing in comparison to normal control, while IgG and IgM content in mice treated with bee pollen ( Pollen of Brassica campes-tris L. ) 10 g/kg/d orally for 1 month were significantly increased.The results showed that the stimulating effect of bee pollen on humoral immunity may be the base of beneficial effect in human being.
