【摘要】 本文采用放射免疫测定技术研究了磁场作用下雄性大白鼠体内两种甲状腺激素—T₄及T₃水平的变化,以求阐明磁场对甲状腺功能的生物学效应。实验结果表明:在表面静磁场为2000GS的旋磁作用下,雄性大白鼠血清中这两种激素的含量均有所增加。但加磁前后Г₄水平的变化不显著（P>0.05）,而加磁后T₃水平的升高则具有统计学意义（P<0.01）。作者认为这一现象提示,磁场可能主要是通过促进T₄向T₃的脱碘转化而使T₃含量增高的。更多还原

【Abstract】 In this paper, radioimmunoassay was applied to study the changes in level of the two thyroid hormones（T₄ and T₃）in male rats under the action of magnetic field, so as to survey its biological effect on thyroid gland function. The result showed that under the action of rotating magnetic field（the strength of the surface static magnetic field being 2000 GS）, these two hormones were increased in serum of male rats. The change of T₄ level was not remarkable from begining to end （P>0.05）. But then, T₃ was going up. It has statistical meaning （P<0.01）. It was suggested that the elevation of serum T₃ concentation was due to the enhanced deiodination process of T₄ to T₃ under the influence of magnetic field.更多还原
