INTRODUCTION
The research examined the antioxidative impact of astragalosides (AST) on experimental acute pancreatitis (AP) in mice. This study aims to assess the correlation between varying doses of astragalosides and superoxide dismutase (SOD) activity in an acute pancreatitis mouse model. By examining the interplay between astragaloside's protective effects and its antioxidant properties, we aim to deepen our understanding of its therapeutic potential in acute pancreatitis.
METHODS
The AP model in mice was induced by retrograde injection of sodium deoxycholate into the biliary and pancreatic ducts. Serum amylase activity was monitored at various time points following induction. Furthermore, 24 hours post-induction, levels of serum nitric oxide (NO), superoxide dismutase (SOD) activity, and malondialdehyde (MDA) content in pancreatic tissue were assessed.
RESULTS
The findings of this study illustrated that AST, while exhibiting a protective effect in experimental AP, could effectively lower the elevated serum NO levels, reduce MDA production, and enhance SOD activity in model mice. AST notably reduced MDA levels in the pancreatic tissue of AP mice, underscoring its ability to inhibit membrane peroxidation induced by oxygen free radicals. Furthermore, AST was observed to elevate SOD activity in scavenging oxygen free radicals in pancreatic tissue.
CONCLUSION
These findings suggest that AST enhances recovery in an experimental acute pancreatitis mouse model by exerting antioxidative effects.
引言
本研究探讨了黄芪总苷(AST)对小鼠实验性急性胰腺炎(AP)的抗氧化作用。本研究旨在评估急性胰腺炎小鼠模型中不同剂量黄芪总苷与超氧化物歧化酶(SOD)活性之间的相关性。通过研究黄芪总苷的保护作用与其抗氧化特性之间的相互作用,我们旨在加深对其在急性胰腺炎中治疗潜力的理解。
方法
通过向胆管和胰管逆行注射脱氧胆酸钠诱导小鼠AP模型。在诱导后的不同时间点监测血清淀粉酶活性。此外,在诱导后24小时,评估胰腺组织中血清一氧化氮(NO)水平、超氧化物歧化酶(SOD)活性和丙二醛(MDA)含量。
结果
本研究结果表明,AST在实验性AP中具有保护作用,可有效降低模型小鼠血清中升高的NO水平,减少MDA生成,并增强SOD活性。AST显著降低了AP小鼠胰腺组织中的MDA水平,突出了其抑制氧自由基诱导的膜过氧化的能力。此外,观察到AST可提高胰腺组织中清除氧自由基的SOD活性。
结论
这些发现表明,AST通过发挥抗氧化作用促进实验性急性胰腺炎小鼠模型的恢复。
