In this report the olfactory bulbs (OB) were removed from 5-6 month, 15-16 month and 25-26 month male Fischer 344 rats and assayed for concentrations of monoamines and their metabolites using HPLC-EC. Concentrations of norepinephrine were…

Levels of pituitary growth hormone (GH) messenger RNA (mRNA) were compared in groups of genetically obese (fa/fa) and lean (Fa/-) littermate male Zucker rats at four different ages, 3, 5, 9, and 11 weeks, in order to determine the earliest age at…

In the present experiment we compared the effects of continuous versus pulsed infusions of L-beta-3,4,dihydroxyphenylalanine (L-DOPA) upon dopamine and 3,4-dihydroxyphenylacetic acid (DOPAC) release in vitro from superfused corpus striatal tissue…

In the present report we examined the effects of estrogen upon catecholamine release from superfused medial basal hypothalamic tissue fragments of pre-pubertal ovariectomized CD-1 mice. Prepubertal mice treated with estradiol benzoate (EB–5…

Previous research has demonstrated that the antinociceptive efficacy of opioids decreases with advancing age. This study utilized radioligand binding techniques to determine if this decline is due to a change in the receptor density (Bmax) and/or…

The purpose of this study was to investigate how the aging process alters the basal levels of serotonin, norepinephrine, dopamine, and their respective metabolites in the spinal cord using high-performance liquid chromatography and electrochemical…
