评价中药体外抑菌法的研究进展

综合评述常用中药体外抑菌评价方法及存在问题，发现评价标准未能统一，结果受主观因素影响大、体外与体内抑菌效果存在一定差异性，未能结合中药特点选择合适的方法。不同抑菌方法对评价中药对细菌的抑制能力（抑菌环、MIC）、杀灭能力（MBC），细菌对药物的耐药率等影响较大。中药体外抑菌作用虽然研究方法较多，应根据研究对象、实验目的、具体条件等选择合适的方法，以便更加准确地评价中药的抗菌作用。

Research progress in evaluation on Chinese materia medica in vitro bacteriostasis methods

After the common evaluation methods of in vitro bacteriostasis by Chinese materia medica (CMM) and the existing problems were comprehensively reviewed, we found that the evaluation criterion was not unified. The results were affected by subjective factors, there were some differences in the antibacterial effect between in vitro and in vivo, and the appropriate method was chosen without combining with the characteristics of CMM. Different bacteriostatic methods had a greater influence on the evaluation of CMM inhibition of bacteria (bacteriostasis circle, MIC), ability to kill (MBC), and the resistance of bacteria to drugs, etc. There are many research methods on the bacteriostasis experiment in vitro of CMM. Therefore, suitable methods should be chosen according to the conditions, aims, and requirements, so as to evaluate the antibacterial effect of CMM more accurately.
