中成药检菌方法繁杂、费时、笔者对此进行了几点改进: 1、平皿采用消洁精(第二军医大学产)浸泡12秒,常以蒸馏水依次冲洗,平皿光洁,无污迹,灭菌后无菌检验,细菌无生长。 2、检菌方法中吸管吸取液体,常常在第一、二稀释度发生管尖堵塞,操作人员只好将吸管尖打碎一部分,影响检菌结果的准确性, The method of detecting bacteria in Chinese patent medicines is complicated and time-consuming. The author has made several improvements: 1. The dish is soaked for 12 seconds with a detergent (produced by the Second Military Medical University), often rinsed with distilled water, and the dishes are clean and free from smudges. Sterility test after bacteria, no growth of bacteria. 2. In the sterilizing method, the pipette sucks liquid, and the tip of the pipe is often jammed in the first and second dilutions. The operator has to break a part of the pipette tip to affect the accuracy of the bacterium detection result.
