To explore the effect of Shengqitang on the ultrastructure changes of the neurons in the mammillary body area in aged(15 month)mice.Methods:morphocy tologic in the mammillary body area were observed by electron microscopy.Results:The contents of lipofuscin in the neurons of the region of the experiment group was reduced as compared with that of the old group.In the Shengqitang treatment group,the normal membrane and the structure of the mitochondrion were clearly seen in the hippocampus neuron in the mice;the ridges of the mitochondrion could clearly be seen,with rich rough endoplasmic reticul...
