手皮肤β辐射损伤患者甲襞微循环改变

The Changes of Fingernail Microcirculation in the Patients with Hand Skin Radiation Damage Caused by β Rays

目的 观察手皮肤β辐射损伤时甲襞微循环的改变。 方法 采用XOX - 1A型微循环显微镜在汞灯冷光下检查 2 2例手皮肤 β辐射损伤 (Ⅲ°～Ⅳ°)患者的甲襞微循环变化。结果 异型管襻、襻周出血及乳头下静脉丛显著增多 ,流速显著减慢 (以粒流为主 ) ,且有明显红细胞聚集。

Objective To observe the microcirculation changes in the patients with hand skin radiation damage caused by β rays.Methods The XOX-1A type microcirculation microscope was used in observation of the microcirculation changes of fingernail,in 22 patients with Ⅲ-Ⅳ degree hand skin radiation damage caused by β rays.Results A series of abnormal signs were observed in all these patients and it was found that the microcirculation abnormity of the fingernail were the most clinical significant sign.Conclusion The fingernail microcirculation changes can be used as an indicator for prognosis in the hand skin radiation damage patients.
