利用放射性~(131)I治疗甲亢在国内已有30多年的历史,由于此方法特异性强、安全、可靠、简便、经济,目前仍是治疗甲亢的重要方法之一。我国从50年代末期开始应用于临床,许多医院在这方面积累了丰富的经验。1984年在全国核素治疗质量控制会上又制定了一系列规程,使此方法更规范化,因而大大地提高了疗效。一、~(131)I治疗甲亢的原理甲状腺具有高度浓聚碘的能力,甲亢时甲状腺组织浓聚碘的能力更强,放射性~(131)I具有一般碘的化学性质,因而口服~(131)I后,~(131)I能迅速而选择性地被甲状腺组织摄取,使部分甲状腺组织受到β射线的集中照射而遭到破坏,从而减少甲状腺激素的合成而达到
The use of radioactive 131I treatment of hyperthyroidism in the country for more than 30 years of history, due to the specificity of this method, safe, reliable, simple and economical, is still an important method of treatment of hyperthyroidism. Since the late 1950s, China has been applied to clinical practice, and many hospitals have accumulated rich experience in this field. In 1984, a series of procedures were formulated at the National Quality Control Conference for Radionuclides to make this method more standardized, thus greatly improving the curative effect. A, 131I treatment of hyperthyroidism principle Thyroid gland has a high concentration of iodine capacity, hyperthyroidism thyroid tissue concentration of iodine stronger ability, radioactive 131I I have a general chemical nature of iodine, which oral ~ (131 ) I, ~ (131) I can quickly and selectively taken by the thyroid tissue, so that part of the thyroid tissue by the concentrated exposure to beta rays were destroyed, thereby reducing the thyroid hormone synthesis and achieve
