摘要
目的探讨大鼠卡氏肺孢子虫包囊的形态学参数特征。方法采用图像分析仪测量大鼠感染的卡氏肺孢子虫包囊的长径、短径、周长、面积、等效直径、圆球度、体积等参数。结果长径最大值7.598μm、最小值3.75μm、平均5.112μm;短径最大值5.94μm,最小值2.94μm、平均4.438μm;周长平均值16.234μm;面积平均值为17.696μm2。结论本研究结果为比较不同宿主来源的卡氏肺孢子虫包囊提供了科学数据。
Objective The aim of this study was to measure morphological characteristic of Pneumocystis carinii cysts in rats. Methods The rats were injected subcutaneously with dexamethasone (1mg per rate) twice a week and were killed to obtain lungs after 10 weeks. The long diameter, short diameter, perimeter, area, equivalent diameter, sphere grade and volume of Pneumocystis carinii cysts in the lung samples were measured by image analyzer. Results The range of the long diameter is from 7.598μm to 3.75μm, with an average of 5.112μm. The range of the short diameter is from 5.94μm to 2.94 μm, with an average of 4.438μm. The average perimeter is 16.234μm and average area is 17.696μm2. Conclusion The results provided a scientific base for comparing Pneumocystis carinii cysts obtaining from different hosts.
