Abstract

The fine structure os spinal ganglia from seven slow lorises (Nycticebus coucang coucang) was studied following perfusion fixation using different concentrations of glutaraldehyde and post-fixation in 1% osmic acid. Two cell types, one light (63%), and the other dark (37%) were reported out of the total number of 425 neurons counted. Almost all the light cells contained filamentous mitochondria, whereas only 35% of the dark cells contained filamentous mitochondria, the other 65% having vacuolated mitochondria. The significance of this mitochondrial variation in the spinal ganglion cells of the slow loris is undecided.

摘要

对7只懒猴(蜂猴指名亚种)的脊髓神经节进行精细结构研究,采用不同浓度的戊二醛灌注固定,随后用1%的锇酸进行后固定。在所计数的425个神经元总数中,报告有两种细胞类型,一种浅色的(63%),另一种深色的(37%)。几乎所有浅色细胞都含有丝状线粒体,而只有35%的深色细胞含有丝状线粒体,另外65%的深色细胞具有空泡化线粒体。懒猴脊髓神经节细胞中线粒体这种变化的意义尚不确定。
