摘要: 用含甲硝唑500 μg/ml(12h LC50)的改良TYI-S-33培养基培养蓝氏贾第鞭毛虫滋养体。分别用光镜和电镜观察药物作用后2、4、8及12 h虫体的形态变化。光镜观察显示:虫体变圆,从培养管壁脱落,鞭毛摆动迟缓或停止,细胞质出现空泡。电镜观察显示:虫体胀大、变圆、细胞质内核糖体溶解,出现大量空泡;核呈锯齿状异形。证实甲硝唑对体外培养的贾第虫滋养体的形态结构有明显的损伤作用。

Abstract: Trophozoites of Giardia lamblia were axenically cultivated with modified TYI-S-33 medium contained 500 μg/ml metronidazole(12h LC50). The morphology of drug-treated trophozoites was observed with light and electron micro-scopes at 2, 4, 8, 12 h respectively. The light microscopy revealed that the trophozoites treated with MTZ showed swollen, detached from the wall of the culture tube, and were with vacuoles in the cytoplasm. Movement of the flagella become slowly or stopped. Electronic microscopy showed that the trophozoites were swollen and deformed; lots of vacuoles were seen in the cytoplasm; the contents of cytoplasm were depleted and the nuclei deformed. This study indicated that MTZ has injured the morphology of G.lamblia.
