Abstract

OBJECTIVES

The current study was conducted to assess the protective mechanisms of BuOH fraction from the aerial part of (BEGC) on APAP-induced liver injury compared to necrostatine-1 (Nec-1).

MATERIALS AND METHODS

A model of APAP-induced hepatotoxicity was created in male rats by injecting a single dose; 1000 mg/kg APAP, the protective effect was performed with (200 mg/kg; 10 days) BEGC compared to Nec-1, (1.8 mg/kg).

RESULTS

BEGC or NeC-1 pretreatment significantly abolished impaired effects in APAP-rats, by decreasing the generation of TBARS and ROS in mitochondrial and cytosolic fractions and maintaining liver function activities. A marked response was observed in the levels of both GSH and GSH-system enzymes in liver homogenates and mitochondrial fractions to BEGC. BEGC/ Nec-1 successfully regulated the inflammatory mediators (IL-β, TNF-α, HMGB1, and acHMGB1) and MPO levels. During APAP treatment, no caspase-3 or -8 activity was detected, and the level of fk18; M30 was higher than the levels of cck18; M65. Moreover, RIPK3 and MLKL levels were increased in the APAP group. These results suggested that necroptosis predominates during the APAP liver injury model. Interestingly, these necroptotic factors were significantly down-regulated by BEGC treatment. Both biochemical and histopathological findings were consistent with each other.

CONCLUSION

From all these findings, the hepatoprotective effect of BEGC could be due to the abundance of polyphenols identified by LC-MS/MS analysis, as well as the synergistic interactions of all contents.

摘要

目的

本研究旨在评估与坏死抑制因子 -1(Nec-1)相比,白背叶根(BEGC)地上部分的正丁醇馏分对乙酰氨基酚(APAP)诱导的肝损伤的保护机制。

材料与方法

通过单次注射1000mg/kg APAP建立雄性大鼠APAP诱导的肝毒性模型,与1.8mg/kg的Nec-1相比,用200mg/kg的BEGC(连续10天)进行保护作用研究。

结果

BEGC或NeC-1预处理通过减少线粒体和胞质组分中丙二醛(TBARS)和活性氧(ROS)的生成并维持肝功能活性,显著消除了APAP诱导大鼠的损伤作用。在肝匀浆和线粒体组分中,谷胱甘肽(GSH)和GSH系统酶水平对BEGC有明显反应。BEGC/Nec-1成功调节了炎症介质(IL-β、TNF-α、HMGB1和乙酰化HMGB1)和髓过氧化物酶(MPO)水平。在APAP治疗期间,未检测到半胱天冬酶 -3或 -8活性,而fk18; M30水平高于cck18; M65水平。此外,APAP组中受体相互作用蛋白激酶3(RIPK3)和混合谱系激酶结构域样蛋白(MLKL)水平升高。这些结果表明在APAP肝损伤模型中坏死性凋亡占主导。有趣的是,BEGC治疗可显著下调这些坏死性凋亡因子。生化和组织病理学结果相互一致。

结论

从所有这些发现来看,BEGC的肝保护作用可能归因于LC-MS/MS分析鉴定出的丰富多酚类物质,以及所有成分的协同相互作用。
