Changes in the distribution of Anionic sites on the synaptosomal membrane of old rats were investigated by means of cationized ferritin. Synaptosomal fraction was isolated from the cerebral cortex of two groups of rats: a control group-rats aged 2 months and second group-rats aged 14 months. Some diminishing of density was established on anionic sites as well grouping in larger or smaller aggregates of the same sites on the membrane of some synaptosomes of old rats.
采用阳离子铁蛋白法研究了老年大鼠突触体膜上阴离子位点分布的变化。从两组大鼠的大脑皮层分离出突触体部分：对照组为2个月龄的大鼠，第二组为14个月龄的大鼠。在老年大鼠的一些突触体膜上，阴离子位点的密度有所降低，并且相同位点形成了大大小小的聚集体。
