Hyperglycemia increases reactive oxygen species (ROS), which contributes to diabetic complications such as kidney cell damage. Antioxidant administration could inhibit ROS and kidney cell damage commonly seen in hyperglycemia.
We want to demonstrate that the antioxidant properties of ethanol extract nanoparticles can prevent kidney cell damage brought on by streptozotocin (STZ) in the current investigation.
This study employs high-energy ball milling to produce nanoparticles from extract. Additionally, dynamic light scattering (DLS) is utilized to characterize the nanoparticle sizes of the ethanol extract. Five groups, each consisting of 8 rats, were formed from 40 rats. Control rats received distilled water, the diabetic rats were administered STZ injections, while rats were given extract nanoparticles orally and STZ injection. After the trial, blood from a rat was drawn intracardially to check the levels of blood urea nitrogen (BUN) and creatinine. The levels of superoxide dismutase (SOD), glutathione peroxidase (GPx), and malondialdehyde (MDA) were then assessed in kidney tissue samples. Histological alterations were evaluated in kidney section samples.
A DLS analysis estimated the size of the ethanol extract nanoparticles to be about 91.50 ± 23.06 nm. BUN and creatinine levels were significantly raised after STZ treatment. STZ significantly decreased SOD and GPx levels in kidney tissue while raising MDA levels ( < 0.05). ethanol extract nanoparticle caused the decreased levels of BUN and creatinine in blood to normal levels ( < 0.05), indicating that ethanol extract prevented the STZ-induced kidney cell damage. Additionally, nanoparticles significantly raise GPx and SOD levels in kidney tissue while lowering MDA levels ( < 0.05). These actions are thought to have prevented kidney histological alterations (degeneration and necrosis) in diabetic rats.
According to these results, the anti-oxidative stress properties of nanoparticles make them potentially effective nephroprotective therapies for STZ-induced kidney cell damage.
高血糖会增加活性氧(ROS),这会导致糖尿病并发症,如肾细胞损伤。给予抗氧化剂可以抑制高血糖中常见的ROS和肾细胞损伤。
在本研究中,我们想要证明乙醇提取物纳米颗粒的抗氧化特性可以预防链脲佐菌素(STZ)引起的肾细胞损伤。
本研究采用高能球磨法从提取物中制备纳米颗粒。此外,利用动态光散射(DLS)来表征乙醇提取物的纳米颗粒尺寸。将40只大鼠分成五组,每组8只。对照组大鼠接受蒸馏水,糖尿病大鼠接受STZ注射,而其他大鼠口服提取物纳米颗粒并接受STZ注射。试验结束后,通过心脏穿刺采集大鼠血液,检测血尿素氮(BUN)和肌酐水平。然后评估肾组织样本中超氧化物歧化酶(SOD)、谷胱甘肽过氧化物酶(GPx)和丙二醛(MDA)的水平。对肾切片样本进行组织学改变评估。
DLS分析估计乙醇提取物纳米颗粒的尺寸约为91.50±23.06nm。STZ处理后,BUN和肌酐水平显著升高。STZ显著降低了肾组织中SOD和GPx水平,同时提高了MDA水平(P<0.05)。乙醇提取物纳米颗粒使血液中BUN和肌酐水平降至正常水平(P<0.05),表明乙醇提取物预防了STZ诱导的肾细胞损伤。此外,纳米颗粒显著提高了肾组织中GPx和SOD水平,同时降低了MDA水平(P<0.05)。这些作用被认为预防了糖尿病大鼠的肾组织学改变(变性和坏死)。
根据这些结果,纳米颗粒的抗氧化应激特性使其有可能成为治疗STZ诱导的肾细胞损伤的有效肾保护疗法。
