Özet

Background A sepsis model was created, induced by cecal ligation and puncture (CLP), in juvenile rat groups. Milrinone (MIL), which is known to have a modulatory effect on pro-inflammatory cytokines, was administered to the designated rat groups in the early period before severe sepsis developed. The study was aimed at investigating the possible protective effects of milrinone on the lung and kidney tissues of rats in the late phase of sepsis. Methods The rat pups were divided into seven groups with six animals in each group: (1) healthy rats who received no drug; (2) CLP-S12 (sacrificed at hour 12); (3) CLP-S24 (sacrificed at hour 24); (4) CLP-MIL1-S12 (administered with 0.5 mg/kg milrinone at hour 1 and sacrificed at hour 12); (5) CLP-MIL1-S24 (administered with 0.5 mg/kg milrinone at hour 1 and sacrificed at hour 24): (6) CLP-MIL12-S24 (administered with 0.5 mg/kg milrinone at hour 12 and sacrificed at hour 24), (7) and CLP-MIL1,12-S24 (administered with 0.5 mg/kg milrinone at hours 1 and 12 and sacrificed at hour 24). Results Significant differences were found between the early and late administration of milrinone in terms of both molecular and histopathological results. The results showed that the tissues were significantly preserved in the groups in which milrinone had been started in the early period compared to the sepsis control groups and the groups in which milrinone had been started in the late period. Conclusions In addition to the positive inotropic effects of milrinone, its immunomodulatory properties that result in decreased cytokine storm can be beneficial during early period of sepsis.
