摘要: Abstract Norepinephrine (NE) uptake has been studied in the adult (3–6 months) and aging (5 yr) chick iris, which there is a discrete population of norepinephrine containing nerve terminals. Although total accumulation 3H-NE iris does not change with age, decline Na+-dependence, temperature-sensitivity, ouabain-and inhibitor-sensitivity uptake. The results indicate either loss active, carrier-mediated NE during aging, or biochemical pharmacological characteristics this Changes composition organ sites are considered.
