过氯酸钾释放试验对高碘性甲状腺肿临床应用初步探讨

The Prliminary Valur of Pechlorate Washout Test in Diagnosis of Iodine Excessive Goliter

目的 探讨过氯酸钾释放试验对高碘性甲状腺肿应用价值。方法 对 29例高碘性甲状腺肿患者及28例正常人进行过氯酸钾释放试验,口服6-10UCi碘后3小时测定吸碘率,然后立即口服过氯酸钾400mg,一小时后再次测定吸碘率。 结果 29例高碘性甲状腺肿患者中有25例过氯酸钾释放试验为阳性,而28例正常人仅有4例为阳性,其阳性率分别为86.2％和14.3％。结论 过氯酸钾释放试验对高碘性甲状腺肿的诊断有一定的临床意义。

Objective To evaluate perchlorate washout test detecting iodine excessive goliter. Methods 29 patients with iodine excessive goliter and 28 normals were undergone perchlorot washout test. Between 6 to 10UCi radioidine is edmin-istered orally and 3hr later the uptake is measured. And then given 400mg of KCLO4 orally and uptake is mesured after 1hr. Results 25 out of 29 patients and 4 out of 28 normals were abnormal in perchlorate washout test,one positive rate was 86. 2%,the other was 14. 3%. Conclusion The perchlorate washout test has clinical significance in detecting in iodine excessive goliter.
