2.5. Biochemical Parameters
Initial and final plasma and erythrocyte samples were collected under fasting conditions, followed by centrifugation (4 °C for 15 min at 3500 rpm) to separate plasma and serum. The samples were stored at −80 °C before biochemical analysis for subsequent tests. Plasma and erythrocyte samples were obtained from the NAC-treated and control group patients. The following initial and final data were recorded: biochemical blood profile acid-base balance: pH; renal function: creatinine, urea, and ions; liver function: glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT); haematometric parameters: leukocytes, neutrophils, lymphocytes, and rate neutrophils/lymphocytes; inflammatory parameters: lactate dehydrogenase (LDH), PCR, lactate, ferritin, D-dimer, and procalcitonin.
