A decrease in the functional neurosecretory cell activity of the rat hypothalamic supraoptical and paraventricular nuclei was seen 30 minutes after a single intramuscular thyroliberin injection (8 micrograms). The size of the neurosecretory cell nucleoli significantly diminished in both centers, while a large amount of intranuclear nucleoli-like bodies appeared in the paraventricular nucleus. The neurosecretory substance content in the posterior hypophysis significantly decreased, indicating an active neurohormone excretion. A possibility of negative feedback between the body thyroliberin level and the state of the Gomori-positive hypothalamic neurosecretory centers is discussed.
单次肌肉注射甲状腺释放激素（8微克）30分钟后，可见大鼠下丘脑视上核和室旁核的功能性神经分泌细胞活性降低。两个核团中神经分泌细胞核仁的大小均显著减小，而室旁核中出现大量核内核仁样小体。垂体后叶中神经分泌物质的含量显著降低，表明神经激素的排泄活跃。本文讨论了机体甲状腺释放激素水平与Gomori阳性下丘脑神经分泌中心状态之间存在负反馈的可能性。
