摘要
本研究利用^(99m)Tc标记717树脂制备符合生理条件的固体实验餐对10例正常人和25例慢性萎缩性胃炎、10例甲亢、5例甲减病人行胃排空时间(GET)测定。结果表明^(99m)Tc标记717树脂核素检查法稳定性好、重复性佳,是合乎生理性的胃运动功能检查法。本实验餐制备简单,便于推广。慢性萎缩性胃炎(GET1/2 62.89±9.13min)较正常对照组(GET1/2 51.62±3.69min)胃排空延迟(P<0.01);甲亢(GET1/2 35.12±10.09min)排空增快(P<0.01)、甲减(GET1/281.86±14.45min)排空延迟(P<0.01)。
In this study,we used 99mTc-resin to make experimental solid meal fitting for physiological condition to detect gastric emptying time of 40 patients,including 25 cases of chronic atrophic gastritis (CAG) ,10 of hyperthyroidism,5 of hypothyroidism,and 10 normal subjects. The results showed that 99mTc-resin redionuclide γ-photography was a stable,well repeatable physiological method for detection of gastric movement function. This method was easily prepared, convenient for widely used. A half of gastric emptying time in CAG(62. 89±9. 13min) was longer(P<0. 01),in hyperthyroidism(35. 12±10. 09min)was shorter(P<0. 01),in hypothyroidism (81. 86±14. 45min)was longer(P<0. 01)than normal controls (51. 62±3. 69min).
