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…

In this report female and male CD-1 mice were treated with a neurotoxic regimen of methamphetamine (MA) to compare gender differences in striatal dopamine depletion and concordant changes in mRNA markers of the transforming growth factor-beta injury…

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…

This article describes the progression of steps followed to demonstrate a gender difference associated with Parkinson's disease (PD) and to gain an understanding of the basis, mechanisms, and implications of this gender specificity. First, a review…

Concentrations and in vitro release of norepinephrine were determined from left and right olfactory bulbs of adult male CD-1 mice. Norepinephrine concentrations from the left olfactory bulbs were significantly greater than those of the right (p…

Male mice treated with MPTP or vehicle were tested for their ability to demonstrate a memory-recognition response as evaluated in a habituation-dishabituation task. Treatment with MPTP severely disrupted the male's habituation-dishabituation response…

Male C57/B1 mice received bilateral intranasal infusions of saline, MPTP or an intraperitoneal injection of MPTP. Infusions were performed using a peristaltic pump at a setting of 100 microliters/min. The MPTP, diluted in saline at concentrations of…

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…

Male retired breeder C57/Bl and CD-1 mice were treated with either MPTP or its vehicle. At 7-10 days post-treatment, catecholamine concentrations within the olfactory bulbs (OB) and hypothalamus were determined. Norepinephrine concentrations within…

Ovariectomized rats treated or not with an estradiol pellet were subjected to an unilateral intrastriatal infusion of 6-hydroxydopamine (6-OHDA). Various parameters of nigrostriatal dopaminergic function as derived from measurements of dopamine and…

Striatal synaptosomes from ovariectomized rats were prepared to examine the effect of 17beta-estradiol on [3H]dopamine uptake. Estradiol inhibited [3H]dopamine uptake in a dose-dependent manner, with an IC50 of 7.2 microM. Use of identical…
