Hepatitis, a significant medical concern owing to its potential to cause acute and chronic liver disease, necessitates early intervention. In this study, we aimed to elucidate the histopathological features of lipopolysaccharide-induced hepatitis in mice, focusing on tissue alterations. The results demonstrated that hepatocytes exhibited decreased eosin staining, indicating cellular shrinkage, whereas sinusoids were swollen with blood cells. Detailed electron microscope analysis identified these blood cells as leukocytes and erythrocytes, which confirmed a thrombus formation within the liver. Pre-treatment with aspirin significantly attenuated these pathological changes, including reductions in inflammatory markers such as C-reactive protein, interleukin-1β, and tumor necrosis factor-alpha. These findings highlight aspirin's anti-inflammatory and antiplatelet effects in mitigating liver inflammation and thrombus formation. In this study, we highlighted the potential of aspirin as a therapeutic agent for liver inflammation, in addition to providing insights into hepatocyte alterations and sinusoidal blood cell aggregation in liver inflammation. Aspirin, through the protection of endothelial cells and reduction of cytokine levels, may have broader applications in managing liver disease and other systemic inflammatory conditions. This emphasizes its value in prevention and therapy.
肝炎因其可能导致急慢性肝病而成为一个重大的医学问题,需要早期干预。在本研究中,我们旨在阐明脂多糖诱导的小鼠肝炎的组织病理学特征,重点关注组织改变。结果表明,肝细胞的嗜酸性染色减少,表明细胞萎缩,而肝血窦因血细胞而肿胀。详细的电子显微镜分析确定这些血细胞为白细胞和红细胞,证实肝脏内形成了血栓。阿司匹林预处理显著减轻了这些病理变化,包括炎症标志物如C反应蛋白、白细胞介素-1β和肿瘤坏死因子-α的减少。这些发现突出了阿司匹林在减轻肝脏炎症和血栓形成方面的抗炎和抗血小板作用。在本研究中,我们强调了阿司匹林作为肝脏炎症治疗药物的潜力,此外还深入了解了肝脏炎症中肝细胞改变和肝血窦血细胞聚集情况。阿司匹林通过保护内皮细胞和降低细胞因子水平,可能在肝病和其他全身性炎症疾病的管理中有更广泛的应用。这强调了其在预防和治疗中的价值。
