摘要:

目的 研究粉防己碱(Tet)对白念珠菌(Candida albicans)生物膜及芽管形成的影响。方法 采用XTT还原比色法观察Tet对C.albicans成膜的影响;将0.01、0.1、1μmol/L的Tet分别与C.albicans悬液共同孵育,显微镜下计数芽管形成率。分别设阳性对照组(两性霉素B与白念珠菌悬液共孵育)和阴性对照组(白念珠菌悬液中不加Tet),试验重复5次。结果 Tet各剂量组对C.albicans生物膜及芽管形成具有明显抑制作用(P<0.05),其作用与药物浓度呈正相关,其中1μmol/L的Tet对C.albicans生物膜及芽管形成的抑制率最高,C.albicans生物膜及芽管形成率低于阴性对照组(P<0.05),1μmol/L的Tet组生物膜及芽管形成率低于0.01及0.1μmol/L组(P<0.05)。与阳性对照组比较,差异无统计学意义(P>0.05)。结论 Tet对体外C.albicans生物膜及芽管形成有一定的抑制作用。

Abstract:

Objective To study the effects of tetrandrine(Tet) on Candida albicans biofilm and germ tube formation.Methods Using the XTT method to observe the effect of Tet on C.albicans biofilm.0.01, 0.1, 1μmol/L of Tet and C.albicans suspensions were incubated together, then the rates of bud tube were counted.The experiment was repeated 5 times.Results Tet had obvious inhibitory effects on C.albicans biofilm and the germ tube(P<0.05).The biofilm and germ tube formation inhibition rate was the highest in 1μmol/L of Tet, compared with the negative control group(P<0.05) and the 0.01, 0.1μmol/L groups(P<0.05).Conclusions Tet had inhibitory effect on C.albicans biofilm and germ tube formation.
