碘撒酸为一种新型胆道造影剂,具有低毒、高效的特点,其类似物碘克酸也具有相同效果。本文主要介绍碘撒酸的合成方法。成品经元素分析,含碘量及含氮量均符合理论值。又经实验表明,碘撒酸钠及碘克酸钠在胆汁中的排泄量及胆汁/尿液排泄比,均明显高于胆影酸钠,故用于胆道造影更为适宜,效果更佳。 Iodosilicate is a new type of biliary contrast agent with low toxicity and high efficiency. Its analogue iodic acid also has the same effect. This article describes the synthesis of iodized acid. Finished product by elemental analysis, iodine content and nitrogen content are in line with the theoretical value. Experiments show that iodine sodium and sodium iodate in bile excretion and bile / urine excretion ratio were significantly higher than sodium dichromate, it is more appropriate for the cholangiography, the effect is better.
