CLP: cecal ligation and puncture; PCT: procalcitonin; HMGB1: high-mobility group box 1; BUN: blood urea nitrogen; ALT: alanine aminotransferase; cTnI: cardiac troponin i; PaO2/FiO2: oxygenation index; MAP: mean arterial pressure; Lac: blood lactate; cfu: colony-forming units. S group: animals that met the septic thresholds after CLP insult (); NS group: animals that did not meet the septic thresholds after CLP insult (). versus baseline, # versus NS group.
