Abstract

By the method of quantitative cytophotometry, the content of ribonucleic acid in neurons and mantle gliocytes of the cat vagus caudal node has been studied after a single maximal overloading of 10 units. It has been stated that a decreased RNA content in the mantle gliocytes is less pronounced; that could be explained by their different nutritional conditions (owing to their various position towards the microvessels of the node), on the one hand, and by different functional loading experienced by the two types of cells under the effect of the extreme factor studied, on the other hand. RNA content in gliocytes is restored more quickly owing to its less decrease, and also owing to a more favourable protein synthesis in glycocytes--"for itself".

摘要

采用定量细胞光度法,研究了猫迷走神经尾节神经元和套层神经胶质细胞在单次10单位最大超载后的核糖核酸含量。结果表明,套层神经胶质细胞中核糖核酸含量的降低不太明显;一方面,这可能是由于它们不同的营养条件(因其相对于神经节微血管的不同位置),另一方面,是由于在研究的极端因素作用下,这两种细胞所经历的不同功能负荷。神经胶质细胞中的核糖核酸含量恢复得更快,这是因为其降低较少,还因为神经胶质细胞自身蛋白质合成更有利。
