研究鹅绒藤对小鼠免疫功能的影响和体外抗菌活性。方法用鹅绒藤浸膏（ＡＥＣＣ）及其正丁醇提取物（ＢＥＣＣ）给实验小鼠灌胃后测定细胞免疫及体液免疫指标。用Ｋ—Ｂ法做了ＡＥＣＣ的药敏试验。结果（１）ＡＥＣＣ对小鼠免疫功能无明显影响，ＢＥＣＣ在高剂量下（３ｇ／ｋｇ·ｄ－１）能增加耳反应程度指数（Ｐ＜０．０５）和胸腺重量（Ｐ＜０．０５），减少巨噬细胞吞噬率和吞噬指数（Ｐ＜０．０１）。在低剂量下（１．５ｇ／ｋｇ·ｄ－１）只能增加耳反应程度指数（Ｐ＜０．０５）；（２）ＡＥＣＣ在各种浓度下无抑菌圈。结论ＢＥＣＣ能增强小鼠细胞免疫功能，ＡＥＣＣ在体外无抗菌活性。
To study the effect of goose down vine on immune function and antibacterial activity in vitro. METHODS: Cellular immunity and humoral immunity were measured after intragastric administration of AECC and BECC to mice. The ABC susceptibility test was performed using the K-B method. Results (1) AECC had no effect on the immune function of mice. BECC increased ear response index (P<0.05) and thymus weight at high dose (3g/kg·d-1) (P<0.05). ), Decrease macrophages phagocytosis rate and phagocytic index (P <0.01). At the low dose (1.5g/kg d-1), the ear response index only increased (P<0.05); (2) AECC had no inhibition zone at various concentrations. Conclusion BECC can enhance the cellular immune function of mice. AECC has no antibacterial activity in vitro.
