【摘要】 <正> 小引人体结石中的胆结石和尿路结石,为结石病中的常见病和多发病。而尿路结石似乎又有地区性的特点,以四川而论,川南多见,川北少见。上述两种结石病的病因和发病学,国内外虽然研究了数百年,但至今尚未查明,因而治疗也就存在问题。我们从医学地质学的观点,研究了这些结石的物质成分及其结构构造特点也许有助于这个问题的解决。更多还原

【Abstract】 We have studied the composition of calculi from the view of medical geology. Calculi is a solid concretion formed in the human body.We have studied the samples from cholecystolithus, cholithus, nephrolithus, cystolith ureterolith, etc.with the method of petrology and the technique of infra-red absorption spectrum. The composition of cholecystolithus was made up of organic matter and carbapatite. For example, the composition of the Patient-Shi’s cholecystolithus was a cholesterinicus component as follow: cholesterin-C₂₇H₄₅OH: 93.4%; bilirubin-C₃₃H₃₆O₆N₄: 0.5%; carbapatite-3Ca （PO₄）₂·CaCO₃（?）: 2.1%. The composition of cholithus, such as Patient-Wang’s, was made up of bilirubin-C₃₃H₃₆O₆N₄: 52.1%, cholesterin-C₂₇H₄₅OH: 27.8% and carbapatite -3Ca （PO₄）₂·CaCO₃ （?）: 1.9%. The texture of cholecystolithus was radiate, concentric and it is crossed or mud texture. The composition of urolithus was made up of mineral component and organic matter: Nephrolith was made up of whewellite-CaC₂O₄·H₂O, hydroxyapatite- Ca₅[PO₄]₃ （OH）, and cystolith: uricacid-C₅H₄O₃N₄, ammonium urate-（NH₄） C₅H₃O₃N₄, struvite-NH₄MgPO₄·6H₂O, sodium urate-Na₂C₅H₂O₆N₄·H₂O, cystine-C₆H₁₂O₄N₂S₂ and carbapatite. The texture of cystolith was conce- ntric. The ureterolith was made up of whewellite, struvite, uricacid, ammonium urateetc.更多还原
