过去研究胃肠道脂肪吸收的方法如平衡试验及十二指肠插管引流等,由于测定手续繁杂,影响因素较多,故临床应用有一定困难。1949年 Thannhauser 及 Stanley 二氏首先应用碘标记的中性脂肪,涂浸于面包中,早餐时给病人吃,然后定时取血检查,发现正常人血内碘高峰在3—6小时内出现,高峰的碘强度为口服剂量的4～6%。此外,还发现2名血内碘高达11～12%,说明血内吸收脂肪较多,称之为高脂肪血症。由于此种方法比较简便,且对某些胃肠吸收障碍的疾病如斯泼卢等有较高的诊断价
In the past, the study of gastrointestinal fat absorption methods such as balance test and duodenal drainage, due to complicated procedures, affecting many factors, it has some difficulties in clinical applications. In 1949, Thannhauser and Stanley first used iodine-labeled neutral fat coated Tu bread, breakfast to the patient to eat, and then regularly check the blood and found that normal blood iodine peak within 3-6 hours, the peak The iodine intensity is 4 to 6% of the oral dose. In addition, also found that 2 blood iodine as high as 11 to 12%, indicating more fat absorption within the blood, known as hyperlipidemia. Because of this method is relatively simple, and some gastrointestinal disorders such as gastrointestinal disorders such as Splash have a higher diagnostic price
