【摘要】 本工作在观察去垂体大鼠血中T₄、T₃动态变化的基础上,主要对喉返神经在调节甲状腺激素分泌方面的作用作了初步的探讨,并观察了通过植物性神经传入的光和冷的刺激对甲状腺T₄、T₃分泌的影响。结果表明:大鼠在去垂体后11d中,血中T₄水平正常,此后逐渐下降;持续光照有助于对去垂体大鼠血中T₄、T₃正常水平的维持;喉返神经对甲状腺T₄、T₃的分泌可能有抑制作用;急性寒冷刺激的甲状腺T₄、T₃的分泌与下丘脑—垂体—甲状腺轴的活动有关。更多还原

【Abstract】 This experiment was designed to study the pituitary-removing effect on the thyroid hormone release. A preliminary investigation on the role of recurrent laryngeal nerve in regulating thyroid hormone release was made. In addition, we evaluated the influence of acute cold stimulus and persistent illumination on thyroid hormone secretion in rats. The results showed that T₄ level in serum from pituitary-removed rats remained normal 1～11 days following surgery, then declined progressively, and a persistent exposure to light might contribute to the maintenance of the normal level of thyroid hormone in pituitary- removed rats. Recurrent laryngeal nerve might inhibit thyroid hormone release. Acute cold stimulation of thyroid hormone release is related to hypothalamo -pituitary-thyroid complex.更多还原
