引言在胸部战伤中,有一部分发生‘凝固血胸’或脓胸,需要进行手术治疗(如肺包膜剥除术,引流术等),如此不但增加伤病员痛苦,延长治疗日期,甚至形成慢性脓胸,造成呼吸机能的严重损失。在细菌学方面,曾发现某些乙型溶血性链球菌能产生溶解血塊的溶纖维蛋白激酶(以下简称激酶)及液化粘稠脓汁的溶核蛋白酶。慢性脓胸包膜形成的初期,包膜的主要固体成分是由渗出液的纖维蛋白及脓汁中核蛋白所组成,如 INTRODUCTION In the case of chest warfare, there is a partial coagulation hemopneumothorax or empyema that requires surgical treatment (such as pulmonary capsulorhexis, drainage, etc.), which not only increases the suffering of the wounded and sick, prolongs the treatment date, and even The formation of chronic empyema, causing severe respiratory function loss. In bacteriology, some hemolytic streptococci have been found to produce clot-soluble fibrinolytic kinases (hereinafter referred to as kinases) and liquefied viscous pus nucleolytic protease. Chronic empyema initial envelope formation, the main solid component of the envelope by the exudate of fibrin and pus nucleus protein composition, such as
