INTRODUCTION: Inflammation and oxidative stress are the main factors ascribed with interruption in the process of renal tissue impairment. The toxicity of different types of nitrosamine is well recognized in animals and humans. Administration of the smallest quantities of diethylnitrosamine or dimethylnitrosamine either orally or parenterally results into renal damage. Therapeutic effects of phytofabricated silver nanoparticles of aqueous extract has been scrutinised in current study for the assessment of renal cancer activity in animal model. METHODOLOGY: Phytofabricated silver nanoparticles were characterized by using different instrumentation. Nephroprotective activity of silver nanoparticles at different doses was evaluated against N-diethylnitrosamine (200 mg/kg b.w., intraperitoneal) in animal model. Serum and renal homogenate were taken to evaluate the renal toxicity markers, oxidative stress, and antioxidant parameter, proinflammatory cytokines and histopathological study. RESULT: Significant outcomes of silver nanoparticles in dose dependent manner down regulated the elevated serum marker, tumour marker enzymes and histopathology observation of repaired tissue assured the renal cancer activity in animals. In addition, profile of enzymatic and non-enzymatic antioxidant, proinflammatory cytokines and tumour promotion marker also favours the anticancer property of silver nanoparticles. CONCLUSION: The data of current study reveals silver nanoparticles ameliorates renal oxidative stress and carcinogenesis which was induced by N-diethylnitrosamine and accredited to antioxidant and anticancer activities of phytofabricated nanoparticles by biological approach.
引言:炎症和氧化应激是导致肾组织损伤过程中断的主要因素。不同类型亚硝胺的毒性在动物和人类中已得到充分认识。口服或肠胃外给予最小剂量的二乙基亚硝胺或二甲基亚硝胺都会导致肾损伤。在当前研究中,已对水提取物植物合成的银纳米颗粒的治疗效果进行了审查,以评估其在动物模型中的肾癌活性。 方法:使用不同仪器对植物合成的银纳米颗粒进行表征。在动物模型中,评估了不同剂量的银纳米颗粒对N-二乙基亚硝胺(200 mg/kg体重,腹腔注射)的肾保护活性。采集血清和肾匀浆以评估肾毒性标志物、氧化应激、抗氧化参数、促炎细胞因子,并进行组织病理学研究。 结果:银纳米颗粒以剂量依赖性方式产生显著效果,下调了升高的血清标志物、肿瘤标志物酶,修复组织的组织病理学观察证实了其在动物中的肾癌活性。此外,酶促和非酶促抗氧化剂、促炎细胞因子和肿瘤促进标志物的情况也有利于银纳米颗粒的抗癌特性。 结论:当前研究数据表明,银纳米颗粒可改善由N-二乙基亚硝胺诱导的肾氧化应激和致癌作用,这归因于通过生物学方法制备的纳米颗粒的抗氧化和抗癌活性。
