A study was made of the 131I radioisotope absorption by the thyroid gland, thyroxin binding by a number of tissues, and also protein-bound iodine (PBI) content in the blood plasma of albino rats after the application of alternating magnetic field (AMF)--industrial frequency 200 Ersted voltage--of various duration and periodicity. Plasma PBI increased in response to the 15-minute AMF application. When the exposure was increased to 6.5 hours and especially to 24 hours there was a reduction of the PBI level and of the process of 131I-thyroxin binding by the tissues of the testes, heart, liver, and spleen. The AMF application for 6.5 hours a day for 5 days resulted in a significant elevation of 131I in the thyroid gland and of the PBI, but the 131I-thyroxin binding by the tissues decreased markedly. It is suggested that functional condition of the thyroid gland and the tissue reaction to thyroxin altered depending on the AMF duration and periodicity of action.
对白化大鼠施加不同持续时间和周期性的交变磁场（AMF）——工业频率200厄斯特电压后，研究了甲状腺对131I放射性同位素的吸收、多种组织对甲状腺素的结合以及血浆中蛋白结合碘（PBI）的含量。施加15分钟的AMF后，血浆PBI增加。当暴露时间增加到6.5小时，尤其是24小时时，PBI水平以及睾丸、心脏、肝脏和脾脏组织对131I -甲状腺素的结合过程均降低。每天施加6.5小时的AMF，持续5天，导致甲状腺中131I和PBI显著升高，但组织对131I -甲状腺素的结合明显减少。提示甲状腺的功能状态以及组织对甲状腺素的反应会根据AMF的作用持续时间和周期性而改变。
