摘要:

目的 探讨家蝇3龄幼虫感染大肠埃希菌后大量增加的血细胞来源。方法 观察对照组及感染大肠埃希菌后4、8、16 h组家蝇3龄幼虫血淋巴的血细胞总数(THC)变化;用流式细胞仪检测感染前后各组家蝇3龄幼虫血细胞周期的变化。结果 感染后4、8、16 h组THC与对照组比较均有显著增加,感染后8 h组THC最高,达(38 920±2274)/μl;对照组幼虫血细胞增殖指数(PI)为15.98%;感染后各组G2/M期和S期细胞增多,PI值均明显增加;感染后4 h组PI值最高,达44.34%。结论 家蝇幼虫血细胞自身具有分裂能力,是其造血功能的重要补充。

Abstract:

Objective The  source  of  noticeably  increased  blood  cells  in  third?instar  Musca domestica larvae  infected  with Escherichia coli (E. coli) was investigated. Methods Changes in the total hemolymph counts (THC) of the third?instar M. domestica larvae infected with E. coli in 4, 8 and 16 h and those of the control group were followed and compared. A flow cytometry was used to identify the changes in the blood cell cycle of the third?instar larvae of each group before and after infection. Results The THCs in 4, 8 and 16 h after infection were significantly elevated compared with that in the control group. Peaking in 8 h after infection, the highest THC reached (38 920±2274)/μl. The blood cell proliferation index (PI) of the control group was 15.98%. After infection, the G2/M phase and S phase cells increased in each group with significantly increased PI values. Peaking in 4 h after infection, the highest PI value reached 44.34%. Conclusion The blood cells of M. domestica larvae have the ability to divide as a supplement to the hematopoietic function.
