摘要
目的:研究发酵乳杆菌(Lactobacilus fermentum,Lb-f)在体内的抗癌活性,以期为研制新的抗癌药物提供实验数据。方法:以0.9%氯化钠注射液为空白对照,左旋咪唑和环磷酰胺为阳性对照,测定Lb-f对人胃癌裸鼠异种移植瘤生长的抑制率;以0.9%氯化钠注射液为空白对照、左旋咪唑为阳性对照测定Lb-f对小鼠单核巨噬细胞系统细胞吞噬功能、迟发性免疫反应、抗绵羊红细胞凝集素抗体滴度的影响。结果:三个剂量组的Lb-f在给药后均能显著抑制人胃癌裸鼠异种移植瘤的生长(与0.9%氯化钠注射液组对比,P<0.05),与左旋咪唑组、环磷酰胺组结果相当。三个剂量组的Lb-f均能显著增强小鼠的细胞吞噬功能、迟发性免疫反应、抗绵羊红细胞凝集素效价(与0.9%氯化钠注射液组对比,P<0.01),比左旋咪唑组稍强。结论:发酵乳杆菌在体内具有一定的抗胃癌活性和免疫活性。
Objective: To investigate the anticaneer activity of Lactobacilus fermentum (Lb-f) in vitro. Method: The inhibitory rate of the tumour of SGC-7901 cells was Determined in nude mice after injection of NS,Lb-f( three groups of different doses) ,Levamisole(LMS) and Cyclophosphamide( CTS), respectively. Result: All of Lb-f in the three groups could inhibit the growth rate of the tumour of SGC-7901 cells in nude mice significantly in 5 -20 days after injection (P 〈 0.01 vs NS). Conclusion: Lb-f have significant anticancer activity and immune activity in vitro.
