Methods: Twenty-four male SD rats were randomly divided into normal control (NC, n=6), protein C activator (PCA, n=6), lipopolysaccharide (LPS, n=6) and LPS+PCA group (n=6). NC group were given normal saline and PCA group were injected protein C activator (0.4 mg/kg) through vein of the tail. LPS group were administered lipopolysaccharide (10 mg/kg, 4h) by intraperitoneal injection method to make the model of septic shock rats. After the animal model was made, LPS+PCA group were injected protein C activator (0.4 mg/kg) through vein of the tail. 30 minutes after the injection, each rat was tested by Medlab biosignal analyzing system for observing mean arterial pressure and left ventricle function, the activity of LDH and iNOS in myocardium and the cuttings of myocardial tissues.
