内容記述 | Both morphological and quantitative changes in electron-dense granules and foamy granules of the brain perivascular macrophages were investigated using senescence accelerated prone mice (SAMP) at different ages.

In this study, SAMPS and control SAMR1, 2-19 months of age, were examined to characterize these granules in perivascular macrophages of the brain. The number of granules were counted in animals of each age studied and were observed to change with aging from dense to foamy granules in perivascular macrophages.
