Abstract

OBJECTIVE

has been reported for its anti-inflammatory properties. However, its efficacy in sepsis has yet to be reported. In this study, we studied the ability of extract (DIE) to rescue mice from septic shock and sepsis.

METHODS

studies included the measurement of secreted nitric oxide, cell viability, gene and protein expression via real-time polymerase chain reaction and western blot, and confocal microscopy in RAW 264.7 cells. studies include a model of septic shock and sepsis in BALB/c mice induced by a lethal and sub-lethal dose of lipopolysaccharide (LPS).

RESULTS

DIE suppressed the expression of proinflammatory cytokines induced by LPS and prevented the translocation of NFB into the nucleus of RAW 264.7 cells. It also prevented reactive oxygen species damage induced by LPS in murine bone marrow-derived macrophages. Models of sepsis and septic shock were established in BALB/ mice and DIE-rescued mice from septic shock. DIE also reversed the increase in tumor necrosis factor- and nitrite levels in the serum of mice induced with sepsis. DIE also prevented the translocation of NFB from the cytosol into the nucleus in murine lungs. Histopathological damage induced by sepsis was reversed in the testis, liver, and lungs of mice.

CONCLUSION

In conclusion, DIE is a suitable candidate for development as a therapeutic agent for sepsis.

摘要

目的

已有报道称其具有抗炎特性。然而,其在脓毒症中的疗效尚未见报道。在本研究中,我们研究了提取物(DIE)拯救小鼠脓毒性休克和脓毒症的能力。

方法

研究包括在RAW 264.7细胞中测量分泌的一氧化氮、细胞活力、通过实时聚合酶链反应和蛋白质印迹法检测基因和蛋白质表达,以及共聚焦显微镜观察。研究还包括用致死和亚致死剂量的脂多糖(LPS)诱导BALB/c小鼠建立脓毒性休克和脓毒症模型。

结果

DIE抑制了LPS诱导的促炎细胞因子的表达,并阻止了NF-κB转位至RAW 264.7细胞的细胞核。它还防止了LPS在小鼠骨髓来源的巨噬细胞中诱导的活性氧损伤。在BALB/c小鼠中建立了脓毒症和脓毒性休克模型,DIE拯救了小鼠的脓毒性休克。DIE还逆转了脓毒症诱导的小鼠血清中肿瘤坏死因子和亚硝酸盐水平的升高。DIE还阻止了NF-κB在小鼠肺中从细胞质转位至细胞核。脓毒症诱导的组织病理学损伤在小鼠的睾丸、肝脏和肺中得到逆转。

结论

总之,DIE是一种适合开发为脓毒症治疗药物的候选物。
