Abstract

X-ray diffraction analysis of bone from chronically uremic but nonacidotic rats with normocalcemia and hyperphosphatemia revealed smaller apatite crystals and an increase in the X-ray amorphous mineral fraction when compared to age-matched, pair-fed control animals, indicating less advanced mineral maturation in the uremic animals. Studies in animals with varied degrees of chronic renal insufficiency revealed a progression of the bone crystal maturational defect with advancing uremia.

摘要

对患有慢性尿毒症但无酸中毒、血钙正常且血磷升高的大鼠的骨骼进行X射线衍射分析发现,与年龄匹配、成对喂养的对照动物相比,其磷灰石晶体更小,X射线无定形矿物质部分增加,这表明尿毒症动物的矿物质成熟程度较低。对不同程度慢性肾功能不全动物的研究表明,随着尿毒症病情进展,骨晶体成熟缺陷也在加重。
