ABSTRACT
This study aimed to evaluate the cardioprotective effects of ghrelin in septic mice, focusing on its anti-inflammatory and antioxidant properties. Thirty-five male Swiss mice (8-12 weeks old, 23-33g) were randomly assigned to five groups (n = 7 each) (1) Normal, fed usual diets, (2) Sham, subjected to anesthesia and laparotomy, (3) Sepsis, subjected to cecal ligation and puncture, (4) Vehicle, given an equivalent volume of intraperitoneal saline injections immediately after cecal ligation and puncture, and (5) Ghrelin-treated, administered 80 µg/kg ghrelin intraperitoneal injections immediately following cecal ligation and puncture. Serum levels of tumor necrosis factor-alpha (TNF-α), macrophage migration inhibitory factor (MIF), toll-like receptor 4 (TLR4), and 8-epi-prostaglandin F2 alpha (8-epi-PGF2α) were measured. The extent of cardiac damage was also evaluated histologically. The mean serum levels of TNF-α, MIF, TLR4, and 8-epi-PGF2α levels were significantly higher in the sepsis and vehicle groups than in the normal and sham groups. The levels were significantly lower in the ghrelin-treated group than in the vehicle and sepsis groups. Histological analysis revealed normal myocardial architecture in the normal and sham groups, whereas the sepsis and vehicle groups had severe myocardial injury. The ghrelin-treated group displayed histological features similar to the sham group, indicating reduced myocardial damage. Ghrelin ameliorated sepsis-induced cardiotoxicity in mice by exhibiting strong anti-inflammatory and antioxidant effects. These findings suggest that ghrelin may be a promising therapeutic candidate for the prevention of sepsis-induced cardiotoxicity.
