has been used to treat ulcer, diabetes, fever, and a variety of stress-related disorders. Acetaminophen (APAP) overdose is the most common cause of drug-induced acute liver injury. In this study, we evaluated the hepatoprotective effect and antioxidant capacity of ethanolic extract of (EFE) on acetaminophen-induced hepatotoxicity in albino rats. Rats were pretreated with EFE (150, 250, 500 mg/kg) and thereafter received 250 mg/kg APA intraperitoneally (i.p.). The normal control group received distilled water, while the negative control group received 250 mg/kg APAP, respectively. Hepatotoxicity and oxidative stress-antioxidant parameters were then assessed. Flavonoids, saponins, steroids, and glycosides, but not phenolics were detected by EFE phytochemical analysis. No mortality was recorded on acute exposure of rats to varying concentrations of APAP after 24 h; however, a dose-dependent increase in severity of convulsion, urination, and hyperactivity was observed. APAP overdose induced high AST, ALT, ALP, and total bilirubin levels in the serum, invoked lipid peroxidation, depleted GSH, decreased CAT, SOD, and GST levels, respectively. Nitric oxide (NO) level, myeloperoxidase activity, TNF-, IL-1, NF-B, COX-2, MCP-1, and IL-6 were also increased. Importantly, pretreatment of rats with EFE before acetaminophen ameliorated and restored cellular antioxidant status to levels comparable to the control group. Our results show and suggest the hepatoprotective effect of and its ability to modulate cellular antioxidant status supports its use in traditional medicine and renders it safe in treating an oxidative stress-induced hepatic injury.
已被用于治疗溃疡、糖尿病、发热和各种与应激相关的疾病。对乙酰氨基酚(APAP)过量是药物引起的急性肝损伤的最常见原因。在这项研究中,我们评估了 (EFE)对乙酰氨基酚诱导的白化大鼠肝毒性的保肝作用和抗氧化能力。大鼠用 EFE(150、250、500mg/kg)预处理,然后腹腔内(i.p.)给予 250mg/kg APAP。正常对照组给予蒸馏水,阴性对照组给予 250mg/kg APAP。然后评估肝毒性和氧化应激-抗氧化参数。通过 EFE 植物化学分析检测到类黄酮、皂苷、类固醇和糖苷,但未检测到酚类。在 24 小时内,大鼠急性接触不同浓度的 APAP 时未记录到死亡;然而,观察到抽搐、排尿和多动的严重程度呈剂量依赖性增加。APAP 过量会导致血清中 AST、ALT、ALP 和总胆红素水平升高,引发脂质过氧化,耗尽 GSH,降低 CAT、SOD 和 GST 水平。一氧化氮(NO)水平、髓过氧化物酶活性、TNF-α、IL-1、NF-B、COX-2、MCP-1 和 IL-6 也增加。重要的是,EFE 在给予乙酰氨基酚之前对大鼠进行预处理可改善并恢复细胞抗氧化状态,使其水平与对照组相当。我们的研究结果表明, 具有保肝作用,并能调节细胞抗氧化状态,支持其在传统医学中的应用,并使其在治疗氧化应激诱导的肝损伤时安全。
