摘要: : This study analyzed dopamine (DA) and norepinephrine (NE) in the synaptic vesicles cytoplasm of brains rats 2 months 14 months. The data revealed a clear NE increase 14-month-old rats, contrasting with cytoplasmic fraction rat brain, which remained unchanged age. Synaptic from different regions including those striatum, consistently exhibited higher than DA concentrations, suggesting that they are predominantly noradrenergic. In concentrations vesicular fractions did not vary age, whereas superior cervical ganglia increased older rats. L-3,4-Dihydroxyphenylalanine administration significantly without affecting all ages. such treatment raised only an facilitation transport into may account for
