本制品根据微生态学原理，利用微生物间的拮抗作用，由枯草芽孢杆菌ＢＳ２２４活菌体制成的生物制品，喷涂于创面，达到治疗烧伤创面感染的目的。为了研究用药后枯草杆菌是否会扩散而造成环境污染，由北京解放军三○四医院和北京积水潭医院等四家单位，联合对本制品进行了用药前后病房、环境空气及被服的细菌学监测。结果表明，应用本品治疗烧伤创面，病房及周围环境的枯草芽胞杆菌始终维持在相对低值水平，并未因应用时间延长而使该菌持续增多，亦未发现任何危害。所以应用本制品不仅不会造成环境污染，而且有利于环境的生态平衡
The product according to the principle of micro-ecology, the use of antagonism between microbes, Bacillus subtilis BS224 live bacteria made of biological products, spray wounds to achieve the purpose of treatment of burn wound infection. In order to study whether the Bacillus subtilis after treatment will cause environmental pollution, four units including Beijing People’s Liberation Army 340 Hospital and Beijing Jishuitan Hospital will jointly carry out bacteriological monitoring of ward, ambient air and clothing before and after treatment. The results show that the application of this product for the treatment of burn wounds, wards and the surrounding environment Bacillus subtilis has always been maintained at a relatively low level, did not extend the application of the bacteria continued to increase, did not find any harm. Therefore, the application of this product not only will not cause environmental pollution, but also conducive to the ecological balance of the environment
