中文摘要：

目的研究云南松松塔提取物对正常小鼠免疫功能的影响.方法：昆明种小鼠灌胃给予高、中、低剂量（400、200、100mg/kg）的松塔提取物,阳性对照药左旋咪唑（25 mg/kg）,连续给药10 d后,处死小鼠,测定小鼠血清中免疫球蛋白IgA、IgM、IgG和补体C3、C4的含量,测全外周血细胞数,计算脾脏指数和胸腺指数.结果：云南松松塔提取物能增加外周血中的免疫球蛋白IgA、IgM、补体C4的含量和白细胞数,与正常组相比差异均具有统计学意义（P 〈0.05）.结论：云南松松塔提取物对正常小鼠的免疫功能有-定的增强作用.

英文摘要：

Objective To study the effect of pinecone extract of Pinus Yunnanensis on immune function of normal mice. Methods：Kunming mice were administered high, middle and low dose of pinecone extract（400,200,100 mg/kg）, 25 mg/kg Levamisole by gavageand the mice were sacrificed after 10 days. The content of immunoglobulin IgA, IgM, IgG, complement C3 and C4 in mice serum wasmeasured; the amount of peripheral blood cell, spleen index, and thymus index were measured as well. Results： The pinecone extractof Pinus Yunnanensis could increase immunoglobulin IgA, IgM, complements C4 and WBC in peripheral blood content. Compared withnormal group, the difference reflects statistical significance（P 〈0.05）. Conclusion： The pinecone extract of Pinus Yunnanensis canenhance the immune function of normal mice .
