The effects of sound stimulation (electric bell, 110 dB) on the pineal glands of adult female rats were studied. Two types of animals were selected: audiogenic (Adg) and nonaudiogenic (Nadg). Unlike the Nadg rats, Adg rats exhibited tonic-clonic seizures in response to stimulation. In Adg rats, after a single seizure, all pinealocyte nuclei were pyknotic and the characteristic lobular organization of the pineal was markedly disrupted, indicating intense glandular stress; however, neither serotonin levels nor its biosynthesis were significantly altered. These results suggest a physiopathological relationship between audiogenic seizures and the pineal gland.
研究了声音刺激(电铃,110分贝)对成年雌性大鼠松果体的影响。选取了两种类型的动物:听源性发作(Adg)和非听源性发作(Nadg)。与Nadg大鼠不同,Adg大鼠在受到刺激时会出现强直阵挛性发作。在Adg大鼠中,单次发作后,所有松果体细胞的细胞核都发生了固缩,松果体特有的小叶结构明显被破坏,表明腺体受到强烈应激;然而,血清素水平及其生物合成均未发生显著改变。这些结果提示听源性发作与松果体之间存在生理病理关系。
