Cecal ligation and puncture (CLP) is a commonly used model of sepsis in vivo. We investigated the effects of dexpanthenol (DXP) on heart, lung and aorta in CLP-induced sepsis in rats. Rats were divided into four groups of eight: group 1, sham (SH); group 2 (DXP), 500 mg/kg DXP injected intraperitoneally (i.p.); group 3 (CLP), CLP performed; group 4 (CLP + DXP), 500 mg/kg DXP injected i.p. after CLP. Heart, lung and aorta specimens were harvested for histopathological and biochemical analysis. Heart rate increased in group 3 compared to group 1; DXP administration to group 4 did not alleviate this change. In heart tissue samples, MDA levels were decreased signi?cantly in groups 2 and 4 compared to group 3. The levels of GSH in groups 2 and 3 were elevated compared to groups 1 and 2. SOD activity was increased significantly in group 4 compared to group 3. CAT activity for group 4 was increased significantly compared to groups 1 and 3. We found that caspase-9 and caspase-3 activity was increased after application of CLP. Also, DXP treatment decreased the number of caspase-positive cells significantly compared to group 3. DXP appears to be promising for reducing sepsis-related mortality.
