我们曾用死卡介苗(简称死卡)防治老年慢性支气管炎取得效果,随后我们与湘潭制药厂共同研制“卡虎素”(其中含有死卡)治疗支气管哮喘亦取得一定效果。在制备卡虎素的生产流程中,首先必须研碎死卡。该厂于1986年3月间,曾在一次研究死卡过程中改用了100目的筛子(孔径为0.154mm)参加此制作车间的12名工作人员,事先未注意防护措施,连 We have used dead BCG (referred to as dead card) to prevent and treat chronic bronchitis in elderly patients. After that, we jointly developed “Kashilsu” (which contains dead card) with Xiangtan Pharmaceutical Factory for the treatment of bronchial asthma. In the production of kapok production process, we must first crush dead card. In March 1986, the factory switched to using a 100-mesh sieve (0.154 mm diameter hole) in a study of dead cards. Twelve staff members participated in the workshop without any prior protection measures.
