Study on andrographolide-induced apoptosis of Candida albicans biofilm dispersion cells / 中国中药杂志

ABSTRACT

<p><b>OBJECTIVE</b>To detect the effect of andrographolide on apoptosis of Candida albicans biofilm dispersion cells.</p><p><b>METHOD</b>The morphological changes of apoptotic C. albicans biofilm cells were observed by using Hoechst 33258 staining Fluorescence microscope; changes of mitochondrial membrane potential (MMP) of C. albicans biofilm cells were detected by rhodamine 123 staining flow cytometry; and reactive oxygen species (ROS) was detected by DHR staining flow cytometry.</p><p><b>RESULT</b>1 000, 100 micromol x L(-1) of andrographolide could cause pyknosis and dense staining of C. albicans biofilm cells, 1 000, 100, 10 micromol x L(-1) of andrographolide could decrease MMP and increase ROS of C. albicans biofilm cells.</p><p><b>CONCLUSION</b>Andrographolide of appropriate concentrations could induce apoptosis of dispersion cells of C. albicans biofilms.</p>
