This study was carried out on six adult red kangaroos of both sexes. To determine the location of the oligodendrocytes (OLGs) of the hippocampus (Hip) and corpus callosum (CC), the method of impregnation of the neuroglia with silver salts was applied. The iron distribution in the OLGs was determined by the histochemical method. The Nissl method was used to determine the location of the brain structure and to analyze the number of OLGs. In the Hip, these cells are located one beside another, mainly in blood vessels and neurons; in the neocortex (NC), they are located in layers I-VI; and in the CC, they are arranged in characteristic rows and accompany both nerve fibers and blood vessels. The analysis of the results obtained by the chosen methods in the Hip, NC, and CC in males and females did not show statistically significant differences in the distribution and location of the red kangaroo OLGs. The involvement of these cells is a physiological process that proceeds in a similar manner throughout the life of individuals and actively influences the metabolism of neurons and myelin.
本研究对6只成年红袋鼠（雌雄皆有）进行。为确定海马体（Hip）和胼胝体（CC）中少突胶质细胞（OLGs）的位置，采用了银盐浸染神经胶质的方法。通过组织化学方法测定OLGs中的铁分布。采用尼氏染色法确定脑结构的位置并分析OLGs的数量。在海马体中，这些细胞彼此相邻，主要位于血管和神经元中；在新皮层（NC）中，它们位于I - VI层；在胼胝体中，它们排列成特征性的行，并伴随神经纤维和血管。对雄性和雌性红袋鼠在海马体、新皮层和胼胝体中通过所选方法获得的结果进行分析，结果显示红袋鼠OLGs的分布和位置在统计学上没有显著差异。这些细胞的参与是一个生理过程，在个体的整个生命过程中以类似的方式进行，并积极影响神经元和髓磷脂的代谢。
