Article Snippet: At predetermined time intervals (after 0, 5, 30, and 60 min of circulation), rabbit blood was collected for biochemical analysis, including thrombin-antithrombin complex (TAT, CUSABIO), fibrinolytic-α2 fibrinolytic inhibitor complex (PIC, mlbio), thrombomodulin (TM, mlbio), platelet (PLT), white blood cell (WBC), serum albumin (ALB, proteintech), C-reactive protein (CRP, proteintech), tumor necrosis factor-α (TNF-α, proteintech), and inflammatory and immunosuppressive factors (IL-6, IL-10, proteintech) to assess physiological parameters such as coagulation, inflammatory response, and organ function.
