| 中文摘要: |
| 泌尿系结石是临床上的常见病和多发病,可生长于肾盂、肾实质、输尿管以及膀胱中,较大的结石常会导致尿道阻塞、感染甚至肾脏坏死等病变,是一种严重危害人体健康的泌尿系统疾病。尿结石是动物体内异常生物矿化的产物,其主要成分有草酸钙、磷酸铵镁、尿酸等,其中以草酸钙最为常见。本研究直接取肾结石病人排出体外的自然结石和尿液中的结石微晶作为研究对象,采用透射电子显微镜(TEM)、扫描电子显微镜(SEM)、X-射线衍射分析(XRD)和傅立叶变换红外光谱(FT-IR)等手段对尿结石进行了表征分析。 |
| 英文摘要: |
| Urinary calculus is a serious hazard to human health and diseases of urinary system in clinic. It can be grown in the renal pelvis, renal, ureter and bladder, the larger stones often lead to obstruction of the urinary tract, infection or necrosis of the kidneys and other diseases. Urinary calculus is a product of the animal abnormal biomineralization, its main ingredients are calcium oxalate, magnesium ammonium phosphate and uric acid. Calcium oxalate is the most common of one which. In this study, direct access to the patient with renal stones excreted in urine of natural stone and stone microcrystal, using transmission electron microscopy (TEM), scanning electron microscopy (SEM), X- ray diffraction (XRD) and Fu Liye transform infrared spectroscopy (FT-IR) and other methods were used to characterize the urinary calculus. It is concluded that agglomeration of urinary nanocrystallites is a key factor leading to rapid growth of the crystallites and formation of urinary stones. Through the regulation of physical and chemical properties of nanocrystallites, the formation and recurrence of urinary stones are possible inhibited. |
