【摘要】 根据胆石的红外吸收光谱可将468例胆石分为六型:胆色素型249例,胆固醇型165例,胆色素-胆固醇混合型25例,以上三型共占93.8％。还有碳酸盐型20例,磷酸盐型7例,脂肪酸盐型2例。通过化学定性定量、原子发射光谱、远红外光谱分析,结果表明,化学定性定量分型法与红外光谱分型法基本一致。更多还原

【Abstract】 Gallstones from 468 cases were classified according to their infrared spectra. Of these specimens, 249, 165 and 25 cases were divided into pigment type, cholesterol type and pigment-cholesterol mixed type respectively; and cases within these three types accounted for 93.8％. In addition, 20, 7 and 2 cases were classified with carbonate type, phosphate type and fatty acid salt type respectixely. The result of quantitative, qualitative, atomic spectra and far-infrared spectra analysis suggested that infrared spectra classification of gallstones actually indicated the differeces in their chemical components and structure. This method was sensitive, convenent and rapid. This demonstrated that chemical analysisis also quite reliable. It would be advisable to promote this qualitative method in investigating the gallstone incidence in our country.更多还原
