从云南省第一人民医院得到经过医学证实的典型三聚氰胺肾结石,将2 mg肾结石与200 mg KBr一同放入玛瑙研钵中研碎,进行压片.用Perkin-Elemer公司生产的spectrum 100光谱仪得到了该结石的红外光谱.吸收峰在4 000~2 000 cm~(-1) 之间有3 487,3 325,3 162,2 788 cm~(-1),在1 700~1 000 cm~(-1)之间有1 694,1 555,1 383,1 340,1 189,1 122cm~(-1),在1 000~400 cm~(-1)之间有993,782,748,709,624,585,565,476 cm~(-1).结石的红外光谱经过与文献报道的饲喂含氰尿酸、三聚氰胺宠物饲料后猫的肾结石的红外光谱图及普通人肾结石的红外光谱图财比,相差很大,说明该患儿结石与宠物结石及普通人肾结石的成分相同的可能性不大;分别与三聚氰胺与尿酸的红外光谱图对比,各有50%的相似性;将三聚氰胺、尿酸按1:1混合后,红外光谱出现的峰在4 000~2 000 cm~(-1)之间有3 469,3 419,3 333,3 132,3 026,2 827cm~(-1),在1 700~1 000 cm~(-1)之间有1 696,1 656,1 555,1 489,1 439,1 350,1 311,1 198,1 124,1 028cm~(-1),在1 000~400 cm~(-1)之间有993,878,814,784,745,708,619,577,475 cm~(-1),将其与结石的红外光谱对比,发现两张图谱有83.3%的相似性,由此得出典型三聚氰胺尿结石的主要成分为三聚氰胺和尿酸.
從雲南省第一人民醫院得到經過醫學證實的典型三聚氰胺腎結石,將2 mg腎結石與200 mg KBr一同放入瑪瑙研缽中研碎,進行壓片.用Perkin-Elemer公司生產的spectrum 100光譜儀得到瞭該結石的紅外光譜.吸收峰在4 000~2 000 cm~(-1) 之間有3 487,3 325,3 162,2 788 cm~(-1),在1 700~1 000 cm~(-1)之間有1 694,1 555,1 383,1 340,1 189,1 122cm~(-1),在1 000~400 cm~(-1)之間有993,782,748,709,624,585,565,476 cm~(-1).結石的紅外光譜經過與文獻報道的飼餵含氰尿痠、三聚氰胺寵物飼料後貓的腎結石的紅外光譜圖及普通人腎結石的紅外光譜圖財比,相差很大,說明該患兒結石與寵物結石及普通人腎結石的成分相同的可能性不大;分彆與三聚氰胺與尿痠的紅外光譜圖對比,各有50%的相似性;將三聚氰胺、尿痠按1:1混閤後,紅外光譜齣現的峰在4 000~2 000 cm~(-1)之間有3 469,3 419,3 333,3 132,3 026,2 827cm~(-1),在1 700~1 000 cm~(-1)之間有1 696,1 656,1 555,1 489,1 439,1 350,1 311,1 198,1 124,1 028cm~(-1),在1 000~400 cm~(-1)之間有993,878,814,784,745,708,619,577,475 cm~(-1),將其與結石的紅外光譜對比,髮現兩張圖譜有83.3%的相似性,由此得齣典型三聚氰胺尿結石的主要成分為三聚氰胺和尿痠.

A typical melamine kidney stone confirmed by some medicine expert was collected from the first people's hospital of Yunnan.The kidney stone was adequately determined by PE corporation spectra 100(with resolution of 1 cm~(-1)).The stone samples for FTIR analysis were prepared using the KBr pellet technique,where 2 mg of the pretreated stone powder was mixed with 200 nag of analytical grade KBr using an agate pestle and mortar.The digital spectrum was then scanned in the mid-infrared region from 4 000 to 400 cm~(-1) at room temperature.The appearing bands between 4 000 and 2 000 cm~(-1) were 3 487,3 325,3 162 and 2 788 cm~(-1),those between 1 700 and 1 000 cm~(-1) were 1 694,1 555,1 383,1 340,1 189 and 1 122 cm~(-1),and those between 1 000 and 400 cm~(-1) were 993,782,748,709,624,585,565 and 476 cm~(-1).It was found that the main constituent of calculi showed few comparability with cat kidney stone,which was from cats that died after consuming the contaminated food,and confirmed that these deposits were primarily composed of melamine and cyanuric acid compared to the IR spectra of calculi in literature.It was also found that the main constituent of calculi showed few comparability with popular kidney stone by comparison with the IR spectra of calculi in literature The spectrum of calculi was 50% respectively similar with melamine and uric acid as compared with the IR spectrum.It was found that the main constituent of calculi was melamine itself and uric acid as com3 333,3 132,3 026,2 827 cm~(-1),those between 1 700 and 1 000 cm~(-1) were 1 696,1 656,1 555,1 489,1 439,1 350,1 311,1 198,1 124 and 1 028 cm~(-1),and those between 1 000 and 400 cm~(-1) were 993,878,814,784,745,708,619,577 and 475 cm~(-1).
