本文采用常规法,离心法,离心-薄膜过滤法对五批拨云锭的控制菌检查方法进行了研究考察.实验结果表明:常规法和离心法都不能同时检出标准所要求检查的控制菌.离心-薄膜过滤法尽管能完全消除该药品的抑菌作用,但又有污染菌丢失的可能存在.应因控制菌的不同而采用不同的处理方法来消除抑菌作用. In this paper, the control bacteria inspection methods of the five batches of Radix ingots were studied by conventional method, centrifugal method and centrifugation-membrane filter method. The experimental results show that neither the conventional method nor the centrifugation method can detect the control bacteria required by the standard at the same time. Although the centrifugation-membrane filtration method can completely eliminate the antibacterial effect of the drug, there may be the loss of the contaminating bacteria. Different control methods should be adopted to eliminate the antibacterial effect.
