前言促菌生是一种活菌制剂。它是用我们从土壤中分离出来的DM423菌株制成的。促菌生的作用,是通过其吸氧能力,降低肠腔内氧化还原电位,促进在数量上和种类上都占绝对优势的正常菌群中的厌氧菌成员的生长和繁殖。利用这个特点,我们把促菌生用于调整菌群失调,做为微生物生态防治的一个手段。本文就促菌生的研制、临床应用和作用机制进行了研究。 Introduction Propolis is a viable bacteria preparation. It is made from the DM423 strain that we isolated from the soil. The role of syphilis is through its ability to reduce oxygen in the intestine to promote the growth and reproduction of anaerobic members of normal flora that are both predominant in quantity and in species. Using this feature, we use syphilis as a means of regulating microbial flora as a means of ecological control of microbes. In this paper, the development of bacterial growth, clinical application and mechanism of action were studied.
