微波照射对大鼠造血系统影响的实验研究

Effect of microwave radiation on the rat hematopoietic system

目的探讨微波照射对大鼠造血系统影响的程度和时相性。方法采用血细胞分析和瑞姬氏染色的方法对不同微波辐射剂量照射组的Wistar大鼠在不同时间段(1天、7天、14天)的外周血细胞及骨髓象进行分析。结果微波照射组大鼠血液中的各种细胞参数相对于空白对照组有不同的改变,骨髓象破坏现象明显;以辐射剂量为200 mW/cm2照射后的第7d改变更为显著。而第14d时除WBC、LY#、MID#、N#升高,PLT和PCT仍然减低外其他参数均恢复至空白对照组。结论微波辐射对大鼠的血液系统有影响,且随着辐射剂量的加大,影响越显著。

Objective Discuss the effect degree and phase of microwave radiation on the hematopoietic system in rats,and to provide basis for human health life.Methods Use the methods of blood cell analysis and Wright-Gimsa stain to analyse the peripheral blood cell and marrow smear of the different time（1d,7d and 14d） Wistar rats that exposured by different radiation dose.Results Compare with the untreated control group,various cell parameters of blood in the microwave radiation rats had different changes,and their marrow smear was obviously destroyed;especially the group treated with 200 mW/cm2 microwave exposure had more significant change at seven-day.For the 14d group,the other hematological parameters all return to control except WBC、LY#、MID# and N# increase,PLT and PCT remain lower.Conclusion Microwave radiation can influence hematological system of rats,and with the radiation dose increased,the effect is more significant.
