成石性胆汁钙、镁组成变化的意义

A STUDY ON CONSTITUTIVE CHANGES OF CALCIUM AND MAGNESIUM IN LITHOGENIC BILE

应用原子吸收光谱法测定了57例胆汁中的钙、镁含量,探讨了成石性胆汁钙、镁组成变化与胆石形成的关系。研究结果表明:对照组胆汁钙所占比例(56％)显著低于胆囊结石组(65％)和胆管结石组(75％),而镁所占比例则向反方向变化。作者认为:成石性胆汁钙、镁组成的这种变化证实了钙在成石胆汁中的相对增多及两种成石性胆汁间钙、镁组成的差异,是表示成石性胆汁钙、镁含量变化及钙、镁与胆石形成关系的可靠指标。

The concentration of calcium and magnesium in the bile of 57 patients with and without cholelithiasis was determined using atomic absorption spectrometry, and the constitutive changes of calcium and magnesium were studied. The results showed that the percentage of calcium in total concentration of calcium and magnesium was significantly higher in gallbladder (65%) and duct stone groups (75%) than that in control one (56%), P<0.025, P<0.01 and the difference between two stone groups could also be observed, P<0.001. The changes of the percentage of magnesium was reversed. Author believed that the relative increase of calcium constituent in lithogenic bile, especially in duct stone bile, was a good index for researching the causes of the formation of gallstone and recognizing whether the bile was lithogenic or not with computerassistant diagnostic system.
