为诊断、治疗过敏性疾病,我们自制了粉尘螨制剂。经临床验证,取得较为满意的效果。现将制备方法简介如下:材料取于南京面粉厂装包车间面粉下脚,显微镜下证实有螨的存在。取回的面粉下脚经分级过筛、用丙酮清洗脱脂,直至显微镜下面粉越少越好。烘干后经提取、过滤、酸碱度校正、无菌过滤步骤制成粉尘螨制剂原液。最后经无菌测定、小白鼠毒力试验合格后方可在临床上应用。与人类变态反应有关的螨主要为屋尘螨、粉尘螨和宇尘螨。鉴于粉尘螨(Dermatopha- For the diagnosis, treatment of allergic diseases, we made a dust mite preparation. After clinical verification, to obtain more satisfactory results. Now the preparation method is as follows: The material was taken from the flour mills in Nanjing flour mill plant under the foot, under the microscope confirmed the presence of mites. Remove the flour under the screened grading, degreasing with acetone, until the microscope, the less flour the better. After drying, extraction, filtration, pH correction, sterile filtration steps made dust mites preparation stock solution. After the final determination by aseptic mice toxicity test before passing the clinical application. Mites related to human allergies are mainly house dust mites, dust mites and dust mites. In view of dust mite (Dermatopha-
