2、血空斑數(shù)(采用Jeme改良玻片法)、巨噬細胞吞噬功能(采用半體內法)以及NK細胞活性(采用乳酸脫氫酶法)。結果:SS中、高劑量組提高小鼠脾臟指數(shù)、脾淋巴細胞轉化率、溶血空斑數(shù)、巨噬細胞吞噬率及吞噬指數(shù)、NK細胞活性,與模型對照組比較有顯著性差異(P<0.05)。與模型對照組比較,SS各劑量組胸腺指數(shù)無明顯差異(P>0.05o結論:一定劑量的SS具有增強荷瘤小鼠免疫功能的作用,從而發(fā)揮抗腫瘤作用。關鍵詞:大豆皂苷;荷瘤小鼠;免疫功能中圖分類號:Q95—3,R73,R282.71文獻標識碼:A文章編號:1673-6273(2013)25·4847—04E
