Glycogen concentrations were measured by fluorescence enzymatic assay in rat brains fixed by focused microwave irradiation Regional glycogen concentrations varied 2.5 fold, ranging from 27.1 nmol glucosyl units/mg protein in the striatum to 52.3 nmol/mg protein in the cerebellum and 69.9 nmol/mg protein in the pons-medulla; other regions were intermediate in concentration. Since glycogen is contained primarily within astrocytes, this regional variation may reflect regional differences in astrocyte energy metabolism.
通过荧光酶法测定聚焦微波辐射固定的大鼠脑中的糖原浓度。区域糖原浓度变化2.5倍，范围从纹状体中的27.1 nmol葡萄糖基单位/毫克蛋白质到小脑中的52.3 nmol/毫克蛋白质以及脑桥-延髓中的69.9 nmol/毫克蛋白质；其他区域浓度处于中间水平。由于糖原主要存在于星形胶质细胞内，这种区域差异可能反映了星形胶质细胞能量代谢的区域差异。
