实验性空洞的形成,是为了研究有关空洞的形成、治疗和闭合机制等问题。我们为了缩短形成实验性空洞所需要的时间,提高空洞的出现率,选择了文献记载中最有效的山村氏法,加以改良,在二次抗原中加入增强变态反应性因素,以促进空洞的形成。实验方法及步骤一、菌液的配制: 1.牛型死菌菌悬液的配制: 加热牛型死菌(高压15磅30分) The formation of experimental holes is to study the formation, treatment and closure mechanisms of cavities. In order to shorten the time required for the formation of experimental cavities and increase the occurrence rate of cavities, we selected Yamagata’s method, which is the most effective method in the literature, to be improved and added to the secondary antigen to enhance the formation of cavities . Experimental methods and steps First, the preparation of bacterial liquid: 1. Bovine dead bacteria suspension preparation: heating bovine dead bacteria (high pressure 15 pounds 30 points)
