流动暗房研制及在地方性氟中毒病区X线检查中的应用

目的 探讨流动暗房配合X线防护罩在地方性氟中毒(简称地氟病)病区X线检查中的应用价值.方法 使用流动暗房和固定暗室对地氟病病区320例受检者前臂和小腿X线照片进行冲洗,观察操作效果,通过洗片成像质量,评价对地氟病的诊断效果.结果 流动暗房冲洗照片320例,有指纹印记268个,照片划痕47处,优良照片298例(93.13%),氟骨症检出率47.18%(151/320),Ⅰ期氟骨症检出率26.25%(84/320);固定暗室冲洗照片320例,有指纹印记735个,照片划痕384处,优良照片227例(70.93%),氟骨症检出率34.70%(111/320),Ⅰ期氟骨症检出率16.25%(52/320).优良照片率、氟骨症及Ⅰ期氟骨症检出率比较,流动暗房明显高于固定暗室(χ2值分别为53.43、10.34、9.56,P＜0.01).结论 流动暗房比固定暗室洗片成像质量优越,照片诊断准确率高,在各地氟病病区采用X线流动检查中具有重要的应用价值.

Development of moving darkroom and the value of X-rays photographing in the endemic fluorosis areas

Objective To discuss the value of moving darkroom and accompanying X-rays protective shield in endemic fluorosis areas.Methods Using moving and fixed darkrooms,the X-rays photos of the forearms and shanks of the 320 persons were developed in the endemic fluorosis areas,while the time for development and installing-uninstalling films was documented.The films develpoed in the darkroom were evaluated for the quality.Results Among the 320 films develpoed in the moving darkroom,the 268 had fingerprints,47 had scratches,298 were in good quality(93.13%),while in the fixed darkroom,the figure was correspondingly 735,384,227(70.93%);The moving darkroom increased excellent film rate significantly than fixed darkroom(χ2=53.43,P＜0.01),The detectable rate of skelelal fluorosis and degree Ⅰ skelelal fluorosis were highter than that in the fixed darkroom did (χ2=10.34,χ2=9.56,P＜0.01).Conclusions The films developed in moving darkroom have superior quality and higher diagnostic value,so it is important to use moving X-rays photographing in ecdemic fluorosis areas.
