Adriamycin (Adr) is a cytotoxic anthracycline agent that is utilized to manage many types of tumors, but its clinical use is undesirable due to severe cardiotoxicity. The present study aimed to investigate the cardioprotective effect of () against Adr-induced cardiotoxicity through the antioxidant and anti-inflammatory metabolic pathways. A single dose of Adr was injected in rats to induce cardiotoxicity. Rats are divided into 5 groups, control, 800, Adr, 400 + Adr, and 800 + Adr. 72 h after Adr administration, electrocardiographic (ECG) study was performed for all rats. Serum and hearts were then collected for biochemical and histopathological studies. ameliorated Adr-induced ST-segment elevation. It reduced Adr-induced elevation in lactate dehydrogenase (LDH), creatine kinase-MB (CK-MB), thiobarbituric acid reactive substance (TBARS), tumor necrosis factor-alpha (TNF-), interleukin-1 beta (IL-1), and IL-6. It also protected against Adr-induced histopathological changes. Pretreatment with the extract increased heart tissue contents of glutathione peroxidase (GSH-PX) and reduced glutathione (GSH). Phytochemical analysis of the extract revealed that it is rich in phenolic and flavonoid active constituents. The results of this study revealed that extract ameliorates Adr-induced cardiotoxicity an antioxidant and anti-inflammatory mechanisms. Further studies are warranted in order to recognize the precise active constituents of this natural extract which are responsible for the antioxidant and anti-inflammatory actions.
阿霉素(Adr)是一种细胞毒性蒽环类药物,用于治疗多种类型的肿瘤,但由于严重的心脏毒性,其临床应用并不理想。本研究旨在通过抗氧化和抗炎代谢途径研究 () 对阿霉素诱导的心脏毒性的心脏保护作用。在大鼠中单次注射阿霉素以诱导心脏毒性。将大鼠分为 5 组,对照组、800 组、Adr 组、400+Adr 组和 800+Adr 组。在 Adr 给药后 72 h,对所有大鼠进行心电图(ECG)研究。然后收集血清和心脏进行生化和组织病理学研究。 改善了阿霉素引起的 ST 段抬高。它降低了阿霉素引起的乳酸脱氢酶(LDH)、肌酸激酶-MB(CK-MB)、硫代巴比妥酸反应物质(TBARS)、肿瘤坏死因子-α(TNF-)、白细胞介素-1β(IL-1)和白细胞介素-6(IL-6)的升高。它还可以防止阿霉素引起的组织病理学变化。提取物预处理增加了心脏组织谷胱甘肽过氧化物酶(GSH-PX)和还原型谷胱甘肽(GSH)的含量。提取物的植物化学分析表明,它富含酚类和类黄酮活性成分。本研究结果表明, 提取物通过抗氧化和抗炎机制改善阿霉素诱导的心脏毒性。需要进一步的研究来识别这种天然提取物中负责抗氧化和抗炎作用的确切活性成分。
