放射作业人员的球结膜微循环变化

随着医疗保健事业的发展，电离辐射和放射性核素在医疗中的应用日益广泛，放射诊断与治疗的新技术、新设备不断出现，在提高疾病诊治水平的同时，也增加了对从事放射作业人员安全与健康的疑问，国外也曾开展大量的实验与现场调研，但电离辐射和放射性核素对人体球结膜微循环的影响目前尚不多见，为更深入地了解电离辐射和放射性核素对放射作业人员球结膜微循环的影响，我们对３８名从事放射作业的工作人员进行了球结膜微循环观察。１　资料与方法１．１　对象放射组为３８名从事放射作业的工作人员（放射医师、技师），其中男２５名、女１３…

Changes of Bulbar Conjunctiva Microcirculation on Radiation Operators

Objective: To Study the effects of ionization radiation and radio nuclide on the bulbar conjunctive microcirculation of radiation operators. Methods: Observe the bulbar conjunctiva microcirculation of 38 radiation operators with Tians bulbar conjunctiva microcirculation weighted integral method while observing separately the form, flow regime and peripheral status of the bulbar conjunctiva microcirculation of 35 normal people as the control group and calculating the total. Results: The radiation operators capillaries present apparently more blood deficit areas, poor definition resolution, a larger number, greater diameter, an increasing A/V(above 1∶3) proportion, obviously uneven thickness, disorderly edges, travelness was abnormal. the structure was reticulation and vecicle dilatation. The status of flow showed obviously grain、 sluggish and red blood cell aggregation in flow regime and evident exudation, more hemosiderim deposition and more A/V short circuit was higher( P < 0.05 ~ 0.001 ). Conclusion: Ionization rediation and radio nuclide damage the bulbar conjunctiva microcirculation of radiation operators to different extent. Therefore, it is suggest that the labor hygiene authorites should take further measures to monitor and prevent such damage in a better way.
