Renal ischemia-reperfusion injury (IRI) is a critical health concern that aggravates the pathophysiology of acute kidney injury (AKI), leading to high mortality rates in intensive care units. Cardamonin is a natural compound with anti-inflammatory and antioxidant properties. The current study aimed to evaluate the renoprotective impact of cardamonin against AKI induced by renal IRI. Male rats (n=5 per group) were divided into four groups: the sham group underwent anesthesia and abdominal incision only; the control group experienced bilateral renal artery clamping for 30 minutes followed by 2 hours of reperfusion; the vehicle group received the cardamonin vehicle 30 minutes before ischemia induction; and the cardamonin group was administered 5 mg/kg of cardamonin 30 minutes before ischemia. Blood urea nitrogen (BUN) and creatinine were measured to assess the renal function. Tumor necrosis factor alpha (TNF-α), interleukin 1 beta (IL-1β), interleukin-6 (IL-6), caspase 3, and F2-isoprostane were assessed in renal tissues. Kidney injury was examined using the hematoxylin and eosin stain method. Compared to the sham group, the control group exhibited significantly higher levels of BUN, creatinine, TNF-α, IL-1β, IL-6, F2-isoprostane, and caspase 3 in renal tissues, along with severe kidney injury as evidenced by histological analysis. Compared to the control group, pretreatment with cardamonin resulted in a significant reduction in these biomarkers and alleviated renal damage. Cardamonin had renoprotective effects against renal ischemia and reperfusion injury via modulating inflammation, oxidative stress, and apoptosis pathways.
肾缺血再灌注损伤(IRI)是一个严重的健康问题,会加重急性肾损伤(AKI)的病理生理学,导致重症监护病房的高死亡率。小豆蔻明是一种具有抗炎和抗氧化特性的天然化合物。本研究旨在评估小豆蔻明对肾 IRI 诱导的 AKI 的肾脏保护作用。雄性大鼠(每组 5 只)分为 4 组:假手术组仅接受麻醉和腹部切开;对照组经历双侧肾动脉夹闭 30 分钟,然后再灌注 2 小时;载体组在缺血诱导前 30 分钟给予小豆蔻明载体;小豆蔻明组在缺血前 30 分钟给予 5mg/kg 的小豆蔻明。测定血尿素氮(BUN)和肌酐以评估肾功能。测定肾组织中肿瘤坏死因子-α(TNF-α)、白细胞介素 1β(IL-1β)、白细胞介素 6(IL-6)、半胱天冬酶 3 和 F2-异前列腺素。采用苏木精和伊红染色法检查肾损伤。与假手术组相比,对照组肾组织中 BUN、肌酐、TNF-α、IL-1β、IL-6、F2-异前列腺素和半胱天冬酶 3 水平显著升高,组织学分析表明肾损伤严重。与对照组相比,小豆蔻明预处理可显著降低这些生物标志物,并减轻肾损伤。小豆蔻明通过调节炎症、氧化应激和细胞凋亡途径对肾缺血再灌注损伤具有肾脏保护作用。
