In previous studies pineal "synaptic" ribbons have been shown to undergo striking numerical changes under various physiological and experimental conditions and to be regulated by beta-adrenergic mechanisms. The aim of the present investigation was to study the numbers of pineal "synaptic" ribbons and spherules in Wistar rats throughout the estrous cycle and to compare them with those in males. There were no statistically significant differences in the numbers of ribbons and spherules between males and females and in the females at the different stages of the estrous cycle, indicating that the structures in question, in vivo, do not appear to be regulated by naturally occurring changes of sex steroid hormones and gonadotrophins.
在先前的研究中，松果体“突触”带已被证明在各种生理和实验条件下会发生显著的数量变化，并受β-肾上腺素能机制调节。本研究的目的是研究Wistar大鼠在整个发情周期中松果体“突触”带和小球的数量，并将其与雄性大鼠的数量进行比较。雄性和雌性之间以及处于发情周期不同阶段的雌性之间，带和小球的数量没有统计学上的显著差异，这表明所讨论的结构在体内似乎不受性类固醇激素和促性腺激素自然变化的调节。
