The mechanism of BSCE in the treatment of pulmonary hemorrhage. The BSCE component shortens the activated partial thromboplastin time in the endogenous coagulation pathway by contracting the blood vessel wall, promotes the formation of thrombin in the common pathway of coagulation, and inhibits the conversion of plasminogen into plasmin, reduces the level of tissue plasminogen activator, thereby accelerating blood coagulation.
