目的探讨支气管上皮细胞与原虫类寄生虫鉴别方法。方法比较支气管上皮细胞与寄生虫的形态学特点。结果支气管上皮柱状细胞在形态上与鞭毛虫、纤毛虫等原虫类寄生虫颇为相似,均存在纤毛或鞭毛;尤其是新采取支气管肺泡灌洗液(bronchoalveolar lavage fluid,BALF)中的柱状细胞为活细胞,其细胞和纤毛均为运动状态,极易与原虫类寄生虫混淆而发生误诊;如根据其特点认真鉴别,则不会得出错误结果。结论应认真观察柱状细胞与原虫类寄生虫的主要区别点,从而正确鉴定,以免误诊。
Objective To investigate the method of differentiating bronchial epithelial cells from protozoan parasites. Methods The morphological characteristics of bronchial epithelial cells and parasites were compared. Results The bronchial epithelial columnar cells were similar in morphology to the protozoan parasites such as flagellates and ciliates, and had cilia or flagella. In particular, the columnar cells in bronchoalveolar lavage fluid (BALF) Live cells, their cells and cilia are the state of movement, easy to be confused with protozoan parasites misdiagnosis; If carefully identified according to its characteristics, you will not get wrong results. Conclusions The main difference between columnar cells and protozoan parasite should be carefully observed so that the correct identification can be made to avoid misdiagnosis.
