An evaluation of the rheological properties and the effects of Momordica. charantia L. (M. charantia) nanoparticles and polyethylene glycol (PEG) microspheres adsorbed with M. charantia nanoparticles on the blood of hyperglycemic patients is presented. Blood samples were collected according to glycemic status: normoglycemic (N = 56) and hyperglycemic (N = 26). General and hematological characteristics were determined. Blood rheological parameters were determined at room temperature and under a temperature scan. We determined the effects on whole blood viscosity of treatment with an extract of M. charantia, PEG, or PEG microspheres adsorbed with plant extract. The viscosity of the blood of hyperglycemic patients is greater than that of normoglycemic patients. Nanoparticles of M. charantia extracts lowered blood viscosity at equivalent rates in normo- and hyperglycemic individuals. PEG microspheres did not reduce blood viscosity in hyperglycemic individuals. However, PEG microspheres adsorbed with nanofraction extracts of M. charantia reduced blood viscosity. These data suggest that the effects of diabetes on the viscosity of the blood should be considered. The use of a nanoparticles extract of M. charantia and its adsorption on PEG microspheres may represent an alternative for the control and treatment of blood disorders in diabetic patients.
本文对苦瓜纳米颗粒及吸附有苦瓜纳米颗粒的聚乙二醇(PEG)微球的流变学特性及其对高血糖患者血液的影响进行了评估。根据血糖状况采集血样:血糖正常者(N = 56)和高血糖者(N = 26)。测定了一般和血液学特征。在室温及温度扫描条件下测定血液流变学参数。我们测定了苦瓜提取物、PEG或吸附有植物提取物的PEG微球处理对全血粘度的影响。高血糖患者血液的粘度高于血糖正常患者。苦瓜提取物纳米颗粒在血糖正常和高血糖个体中以相同速率降低血液粘度。PEG微球在高血糖个体中未降低血液粘度。然而,吸附有苦瓜纳米级提取物的PEG微球降低了血液粘度。这些数据表明应考虑糖尿病对血液粘度的影响。使用苦瓜纳米颗粒提取物及其吸附在PEG微球上可能是控制和治疗糖尿病患者血液疾病的一种替代方法。
