磁疗获得的珍珠形胆结石是罕见的病例 ,作者利用红外光谱、扫描电子显微镜及X射线能谱对该胆结石进行了观察和研究。结果表明该胆结石的主要成分为胆固醇 ,并混有少量的蛋白质和无机钙盐 ,说明珍珠形胆结石虽然和珍珠具有相似的形貌 ,但组成是完全不同的。根据扫描电子显微镜的照片 ,作者推测结石的珍珠外形可能是因为片状的胆固醇分子形成胆甾型晶体而形成的。 The pearlitic gallstone obtained by magnetic therapy is a rare case. The authors used infrared spectroscopy, scanning electron microscopy and X-ray spectroscopy to observe and study the gallstones. The results showed that the main component of the gallstone is cholesterol, and mixed with a small amount of protein and inorganic calcium salt, pearl-shaped gallstone although pearl has a similar morphology, but the composition is completely different. According to the photograph of the scanning electron microscope, the authors speculate that the pearl shape of the stone may be formed because of the formation of cholesteric crystals of lamellar cholesterol molecules.
