Valproate is a common antiepileptic drug whose adverse effects include liver steatosis and dyslipidaemia. The aim of our study was to see how natural flavonoid antioxidant naringin would interact with valproate and attenuate these adverse effects. For this reason we treated male C57BL6 mice with a combination of 150 mg/kg of valproate and 25 mg/kg naringin every day for 10 days and compared their serum triglycerides, cholesterol, LDL, HDL, VLDL, and liver PPAR-alpha, PGC-1 alpha, ACOX1, Nrf2, SOD, CAT, GSH, and histological signs of steatosis. Valproate increased lipid peroxidation parameters and caused pronounced microvesicular steatosis throughout the hepatic lobule in all acinar zones, but naringin co-administration limited steatosis to the lobule periphery. In addition, it nearly restored total serum cholesterol, LDL, and triglycerides and liver ACOX1 and MDA to control levels. and upregulated PPAR-alpha and PGC-1 alpha, otherwise severely downregulated by valproate. It also increased SOD activity. All these findings suggest that naringin modulates key lipid metabolism regulators and should further be investigated in this model, either alone or combined with other lipid regulating drugs or molecules.
丙戊酸是一种常见的抗癫痫药物,其不良反应包括肝脂肪变性和血脂异常。我们的研究目的是观察天然类黄酮抗氧化剂柚皮苷如何与丙戊酸相互作用并减轻这些不良反应。为此,我们每天用 150mg/kg 丙戊酸和 25mg/kg 柚皮苷联合治疗雄性 C57BL6 小鼠 10 天,并比较它们的血清甘油三酯、胆固醇、LDL、HDL、VLDL 以及肝组织中 PPAR-α、PGC-1α、ACOX1、Nrf2、SOD、CAT、GSH 和脂肪变性的组织学迹象。丙戊酸增加了脂质过氧化参数,并在所有腺泡区的肝小叶中引起明显的微泡脂肪变性,但柚皮苷共同给药将脂肪变性限制在小叶边缘。此外,它几乎将总血清胆固醇、LDL 和甘油三酯以及肝 ACOX1 和 MDA 恢复到对照水平。并上调 PPAR-α和 PGC-1α,否则丙戊酸严重下调。它还增加了 SOD 活性。所有这些发现表明,柚皮苷调节关键的脂质代谢调节剂,应在该模型中进一步单独或与其他调节脂质的药物或分子一起进行研究。
