本试验应用几种不同方法制备粉尘螨浸液,皮内试验法测定其生物活性,结果表明反复冻融法好于超声波粉碎法、冻融—负压法、磁力搅拌法。
In this study, several different methods were used to prepare Dictyophora piteri dipping solution, and its bioactivity was tested by intradermal test. The results showed that repeated freeze-thaw method was better than ultrasonic pulverization, freeze-thaw-negative pressure method and magnetic stirring method.
