Potential of Casimiroa edulis and Glycosmis pentaphylla leaves extracts were investigated against the effect of two different particle sizes of silver nanoparticles induced toxicity in mice. Mice received silver nanoparticles (AgNPs) (100 mg/kg) with 20 and 100 nm for four weeks followed by daily oral dose of extracts (500 mg/kg) for three weeks. C. edulis leaves identified fourteen phenolic compounds while, G. pentaphylla leaves identified, twelve phenolic compounds. Additionally, biochemical, genotoxicity, mutagenicity, and histopathological investigations were carried out, revealed that liver function activities, lipid profile, hydrogen peroxide, and C‐reactive protein were significantly elevate post AgNPs exposure. While, superoxide dismutase, glutathione‐S‐transferases, and glutathione peroxidase significantly reduce. A marked amelioration in all detected biomarkers, improved histopathological changes and repair DNA damage after treated with C. edulis and G. pentaphylla leaves extracts. These extracts are used for the first time as promising candidate therapeutic agents against toxicity induced by AgNPs.

不同尺寸的银纳米粒子诱导的 DNA 损伤和遗传畸变:卡西米罗阿和五叶糖叶提取物的治疗方法。



研究了卡西米罗五叶糖叶提取物对抗两种不同粒径的银纳米颗粒对小鼠引起的毒性的影响。小鼠接受 20 和 100 nm 的银纳米粒子 (AgNP) (100 mg/kg),持续四个星期,然后每天口服提取物 (500 mg/kg),持续三周。 C. edulis叶子鉴定出 14 种酚类化合物,而G. pentaphylla叶子鉴定出 12 种酚类化合物。此外,还进行了生化、遗传毒性、致突变性和组织病理学研究,结果表明,暴露于 AgNP 后,肝功能活动、脂质谱、过氧化氢和 C 反应蛋白显着升高。同时,超氧化物歧化酶、谷胱甘肽-S-转移酶和谷胱甘肽过氧化物酶显着降低。在用C. edulisG. pentaphylla叶提取物处理后,所有检测到的生物标志物均得到显着改善,改善了组织病理学变化并修复了 DNA 损伤。这些提取物首次被用作对抗 AgNP 引起的毒性的有前景的候选治疗剂。
