摘要
本文研究了突触后致密小体的亚显微结构,发现突触后致密小体与突触后膜有密切的关系,二者之间有细丝连接。突触后致密小体多见于GrayⅠ型突触内,它们具有复杂的形态特点,推测这种结构在突触传递上有重要的作用,可能与兴奋性突触有关。注:本研究承中山大学电镜室和山东医学院电镜室给予帮助,谨致谢意。
The submicroscopic structure of the postsynaptic membrane and the snbsynaptic dense body in the supraoptic nucleus of the hypothalamus of rat were studied.It was found that the subsynaptic dense body and postsynaptic membrane were connected by fine filaments.The subsynaptic dense body was closely related to the postsynaptic membrane and its submicroscopic configuration was complicated.In spite of the obvious differences existing between the subsynaptic dense bodies,nevertheless a typical one was described in this nucleus.It is of interest to note that most subsynaptic dense bodies were mainly encountered within the postsynaptic element of Gray’s TypeⅠsynapse,thus the authors postulated that the subsynaptic dense body would play an important role in the excitatory synapse.
