摘　　要：用电镜技术研究沙土鼠海马ＣＡ＿１区的神经组织超微结构，发现神经毯内的某些线粒体与突触小泡之间有着密切的形态学关系，在部分线粒休内存在着扁平与无颗粒的线粒体小泡，小泡的横径与线粒体嵴的厚度相近，小泡的长轴与线粒体嵴的长轴排列一致。根据突触小泡的形态、大小、电子密度、分布和排列与线粒体小泡相似的事实。笔者认为这两种小泡是同一性质的细胞器。The electron microscopy was used to examine the ultrastructure of the nervoustissue of the hippocampal CA_1 in gerbils.Similar morphological features were found between thesynaptic vesicle and the mitochondria in the hippocampal neuropil.In some mitochondria therewere flat agranular vesicles,whose cross axon was close to the thickness of the mitochondrialcrest.The long axis of the vesicle was arranged in the same way as that of mitochondrial crest.Itwas assumed that two organelles are homologous on the basis of the similar facts in form,size,distribution,arrangement and electronic density between the synaptic vesicle and the mitochon-drial one.
