The effect of carbon monoxide (CO) on the survival rate in the rat model of sepsis induced by cecal ligation and puncture (CLP). Rats from each study group (n=10) were assessed to determine the 7-day survival rate. The Kaplan-Meier survival curves are shown. Male Sprague-Dawley rats (n=120) were divided into six study groups: the sham group; the CLP group; the hemin group (treated with ferric chloride and heme); the zinc protoporphyrin IX (ZnPPIX) group; the CO-releasing molecule 2 (CORM-2) group; and the inactive CORM-2 (iCORM-2) group. FD-4 – fluorescein isothiocyanate-labeled dextran 3000~4000 KDa; CLP – cecal ligation and puncture; CORM-2 – CO-releasing molecule 2; Hemin – ferric chloride heme; ZnPPIX – zinc protoporphyrin IX; iCORM-2 – inactive CORM-2.
