Abstract

Nephroprotection or renal rescue is to revive and restore kidney function after damage, with no need for further dialysis. During acute kidney injury (AKI), sudden and recent reductions in kidney functions occur. Causes are multiple, and prompt intervention can be critical to diminish or prevent morbidity. (ES) is a curative plant with proven pharmacological and biological effects including anti-inflammatory, antioxidant, and antibacterial competencies. The principal goal of this research is to scrutinize the nephroprotective features of extract (ESE) against glycerol-induced AKI. Male Wistar albino rats were equally divided into five separated groups: negative control rats (vehicle-injected), ESE control rats (ESE-treated rats), positive control rats, glycerol-induced AKI-model rats (single IM injection of 50% glycerol), and 2 groups of diseased rats but pretreated with different concentrations of ESE for 7 days (ESE + AKI rats and ESE + AKI rats). Kidney tissues were collected and used for histopathology analysis. The relative kidney weight percentage was assessed. ESE effects were investigated via scanning several biomarkers, such as serum urea and creatinine, as kidney function biomarkers. Lactate dehydrogenase (LDH) and creatine kinase (CK) activities were examined as rhabdomyolysis (RM) indicators. Kidney injury molecule-1 (Kim-1) and neutrophil gelatinase-associated lipocalin (NGAL) were also examined to investigate kidney injury. Enzymatic and nonenzymatic oxidative stress markers were analyzed, namely, superoxide dismutase (SOD), catalase (CAT), glutathione reductase (GR), glutathione peroxidase (GPx), malondialdehyde (MDA), nitric oxide (NO), and reduced glutathione GSH. Proinflammatory cytokine [tumor necrosis factor-α (TNF-α) and interleukin-1 β (IL-1β)] and the renal proapoptotic protein (Bax) and antiapoptotic protein (Bcl-2) levels were evaluated. Statistical analysis for the resulting data revealed that ESE pretreatment turned AKI-induced biological antioxidant levels to an extent comparable to normal results. Furthermore, ESE decreased kidney function markers and RM-related biomarkers (LDH, CK, Kim-1, and NGAL) compared to those in untreated AKI-model rats. ESE treatment dropped the apoptotic renal Bax levels, enhanced antiapoptotic Bcl-2 manufacture, and disallowed the release of IL-1β and TNF-α. This study revealed the protective effect of ESE as therapeutic medicine against AKI-encouraged oxidative stress, inflammation, and apoptosis. It can be effectively used as adjuvant therapy, helping in renal rescue, and for kidney healing in cases with risk factors of AKI.

摘要

肾脏保护或肾脏挽救是指在肾脏受损后恢复和重建肾功能,且无需进一步透析。在急性肾损伤(AKI)期间,肾功能会突然且近期出现下降。病因多种多样,及时干预对于减轻或预防发病至关重要。(ES)是一种具有经证实的药理和生物学作用的药用植物,包括抗炎、抗氧化和抗菌能力。本研究的主要目的是探究提取物(ESE)对甘油诱导的AKI的肾脏保护特性。雄性Wistar白化大鼠被平均分为五组:阴性对照大鼠(注射赋形剂)、ESE对照大鼠(接受ESE治疗的大鼠)、阳性对照大鼠、甘油诱导的AKI模型大鼠(单次肌肉注射50%甘油),以及两组患病大鼠,但预先用不同浓度的ESE处理7天(ESE + AKI大鼠和ESE + AKI大鼠)。收集肾脏组织用于组织病理学分析。评估相对肾脏重量百分比。通过检测几种生物标志物来研究ESE的作用,如血清尿素和肌酐作为肾功能生物标志物。检测乳酸脱氢酶(LDH)和肌酸激酶(CK)活性作为横纹肌溶解(RM)指标。还检测肾脏损伤分子-1(Kim-1)和中性粒细胞明胶酶相关脂质运载蛋白(NGAL)以研究肾脏损伤。分析酶促和非酶促氧化应激标志物,即超氧化物歧化酶(SOD)、过氧化氢酶(CAT)、谷胱甘肽还原酶(GR)、谷胱甘肽过氧化物酶(GPx)、丙二醛(MDA)、一氧化氮(NO)和还原型谷胱甘肽(GSH)。评估促炎细胞因子[肿瘤坏死因子-α(TNF-α)和白细胞介素-1β(IL-1β)]以及肾脏促凋亡蛋白(Bax)和抗凋亡蛋白(Bcl-2)水平。对所得数据的统计分析表明,ESE预处理使AKI诱导的生物抗氧化水平在一定程度上恢复到与正常结果相当的水平。此外,与未治疗的AKI模型大鼠相比,ESE降低了肾功能标志物和与RM相关的生物标志物(LDH、CK、Kim-1和NGAL)。ESE治疗降低了肾脏促凋亡的Bax水平,增强了抗凋亡的Bcl-2生成,并抑制了IL-1β和TNF-α的释放。本研究揭示了ESE作为治疗药物对AKI诱导的氧化应激、炎症和凋亡具有保护作用。它可有效用作辅助治疗,有助于肾脏挽救,并用于有AKI危险因素病例的肾脏愈合。
