Severe burns with delayed resuscitation are associated with high morbidity which is attributed to ischemia-reperfusion injury. This study was undertaken to investigate the effect of hydrogen-rich saline known as a significant selective antioxidant on the inflammatory reaction induced by severe burns with delayed resuscitation. By establishing the model of severe burns with delayed resuscitation in rats, we recorded improvement on the mortality, secretion of cytokines and reaction of oxidative stress of rats treated with hydrogen-rich saline. We found that resuscitation by hydrogen-rich saline alleviated inflammation significantly. We further detected the change of the key nuclear factor NF-κB contributed to inflammation. The expression of both NF-κB and phosphorylated NF-κB in rats having severe burns with delayed resuscitation by hydrogen-rich saline was lower than that in rats with delayed resuscitation with Ringers' solution. Our data imply that hydrogen-rich saline significantly improves the inflammatory reaction in rats with severe burns with delayed resuscitation, possibly by inhibiting activation of NF-κB.
延迟复苏的重度烧伤与高发病率相关,这归因于缺血-再灌注损伤。本研究旨在探讨富含氢气的生理盐水(一种重要的选择性抗氧化剂)对延迟复苏的重度烧伤所致炎症反应的影响。通过建立大鼠延迟复苏的重度烧伤模型,我们记录了用富含氢气的生理盐水治疗的大鼠在死亡率、细胞因子分泌和氧化应激反应方面的改善情况。我们发现,用富含氢气的生理盐水进行复苏可显著减轻炎症。我们进一步检测了导致炎症的关键核因子NF-κB的变化。用富含氢气的生理盐水进行延迟复苏的重度烧伤大鼠中NF-κB和磷酸化NF-κB的表达均低于用林格氏液进行延迟复苏的大鼠。我们的数据表明,富含氢气的生理盐水可显著改善延迟复苏的重度烧伤大鼠的炎症反应,可能是通过抑制NF-κB的激活来实现的。
