Result assay of allergens of 400 cases of chronic urticaria

慢性荨麻疹是一种变态反应性皮肤病，其病因复杂，多数患者找不到确切原因。其中有一部分是由变应原引起的，临床治疗困难，原则上应首先寻找病因并加以去除。为了解变应原在慢性荨麻疹中的作用，笔者使用近年来国际变态反应学广泛采用的皮肤点刺试验（SPT），对中国建筑第三工程局武汉中心医院400例不能明确原因的慢性荨麻疹患者进行了23种变应原的检测。

Abjective To investigate allergens of chronic urticaria, to prevent and treat chronic urticaria- Methods 400 cases of chronic urticaria were tested with 23 kinds of allerger by skin prick test of international method.
