Effects of Dendrobium Compound Granules on Immune Function in Mice

OBJECTIVE To study the effects of the Dendrobium compound granules on the immune function in mice.METHODS ICR mice were randomly divided into 4 groups, included 3 dosage groups (0.65, 1.30, 4.00 g·kg^-1) and a negative control group. The spleen and thymus index, transformation level of lymphoid, carbon clearance index, the content of serum emolysin, the level of delayed type hypersensitivity(DTH), the phagocytic ability of celiac macrophage, the number of antibody formation cell and activity of natural-killer (NK) cells were measured respectively after gavage for 30-39 d.RESULTS Dendrobium compound granules could stimulate the lymphocyte proliferation, increase hemolysin content and DTH level, activity of NK cells, promote the phagocytic rate obviously.CONCLUSION Dendrobium compound granules can enhance the immune function in mice.
