本文是试制一种适合于临床应用的胆固醇示踪物。研制成的I-6-碘代胆固醇在结晶形状,成色反应、沉淀反应及红外线吸收光谱等方面都和胆固醇很相似,且有很高的化学与生物稳定性。此标记物与胆固醇,同时给予家兔或大鼠后,在动物肝、血浆及血管壁动脉粥样硬化斑块中浓度的变化彼此平行。目前它巳用于临床,作为肾上腺显影剂。 This article is a trial of a cholesterol tracer suitable for clinical use. The I-6-iodocholesterol developed is very similar to cholesterol in crystalline form, color reaction, precipitation reaction and infrared absorption spectrum, and has high chemical and biological stability. This marker and cholesterol, given to rabbits or rats, change in concentration in the animal liver, atherosclerotic plaque, and blood vessel walls parallel to each other. It has been used clinically as an adrenal developer.
