Using a variety of chemical compounds and biomolecules, researchers have been working on new antidiabetic drugs for many years. Anti-diabetic research is increasingly using nanomaterials because of their unique qualities, such as their tiny size, biocompatibility, and ability to penetrate cell membranes for drug delivery. Using extract of coated with silver nanoparticles as a model for diabetes mellitus research was one of the goals of this work. Uv-Vis spectroscopy was used to measure the TAgNPs surface plasmon resonance. FTIR spectroscopy confirmed the attached functional groups, XRD analysis confirmed the size and crystallinity, scanning electron microscopy revealed that the majority of the particles were spherical, and EDX performed the elemental analysis. For 21 days, alloxan-induced diabetic Wistar rats (N = 25, n = 5/group) were administered 10 mg/kg body weight of photosynthesized AgNPs as a standard animal model, while those in the untreated normal control group C, received distilled water as a control, diabetics who were treated with 0.5 mg/kg of body weight of glibenclamide, 10 mg/kg of methanolic extract, and diabetics who were given 10 mg/kg of body weight of synthetic AgNPs derived from in the DAgNPs group. At the conclusion of the treatment, lipid, liver and kidney profiles were re-examined to determine whether or not the treatment had been effective (day 21). Oral glucose doses of 2 g/kg of body weight were administered to each group, and blood glucose levels were measured at various intervals (day 21). Fasting glucose levels were measured using a glucometer. Each animal's urine was tested for leukocytes, nitrites, and bilirubin using lab-made prepared assay kits. One-way ANOVA and Dunnett's test were used for statistical analysis. The surface plasmon resonance effect was examined with UV-vis, it showed a sharp peak at 412 nm. X-ray diffraction measurements indicated that the produced nanoparticles were between 15 to 31.44 nm in size. Alloxan-induced diabetic rats were fed AgNPs derived from phytosynthesized AgNPs, compared to diabetic control rats, diabetic rats treated with AgNPs showed a considerable improvement in their dyslipidemia status. Over the course of the days, it also lowered blood glucose levels. A reduction in blood glucose levels, a rise in body weight, and significant improvements in the lipid, liver, and renal profiles were also seen. The present findings revealed that plant mediated silver nanoparticles significantly improved the alloxan induced diabetic changes in various treated rats and might be used for the treatment of diabetes.
多年来,研究人员一直在使用各种化合物和生物分子致力于研发新型抗糖尿病药物。由于纳米材料具有诸如尺寸微小、生物相容性以及能够穿透细胞膜进行药物递送等独特性质,抗糖尿病研究越来越多地使用纳米材料。本研究的目标之一是以包覆银纳米颗粒的提取物作为糖尿病研究的模型。采用紫外可见光谱法测量银纳米颗粒的表面等离子体共振。傅里叶变换红外光谱法证实了附着的官能团,X射线衍射分析确定了尺寸和结晶度,扫描电子显微镜显示大多数颗粒为球形,能量色散X射线光谱进行了元素分析。将四氧嘧啶诱导的糖尿病Wistar大鼠(N = 25,n = 5/组)作为标准动物模型,连续21天给予10mg/kg体重的生物合成银纳米颗粒,而未处理的正常对照组C给予蒸馏水作为对照,用0.5mg/kg体重的格列本脲治疗的糖尿病大鼠、10mg/kg甲醇提取物治疗的糖尿病大鼠,以及在DAgNPs组给予10mg/kg体重合成银纳米颗粒的糖尿病大鼠。在治疗结束时(第21天),重新检查血脂、肝肾功能指标以确定治疗是否有效。给每组大鼠口服2g/kg体重的葡萄糖,在不同时间间隔(第21天)测量血糖水平。使用血糖仪测量空腹血糖水平。使用实验室自制的检测试剂盒检测每只动物尿液中的白细胞、亚硝酸盐和胆红素。采用单因素方差分析和Dunnett检验进行统计分析。用紫外可见光谱检测表面等离子体共振效应,其在412nm处有一个尖锐的峰。X射线衍射测量表明所制备的纳米颗粒尺寸在15至31.44nm之间。与糖尿病对照大鼠相比,给予生物合成银纳米颗粒的糖尿病大鼠血脂异常状况有显著改善。在这几天里,它还降低了血糖水平。还观察到血糖水平降低、体重增加以及血脂、肝肾功能指标有显著改善。目前的研究结果表明,植物介导的银纳米颗粒显著改善了四氧嘧啶诱导的各治疗组大鼠的糖尿病变化,可能用于治疗糖尿病。
