Multiple binding sites for [125I]RTI-121 and other cocaine analogs in rat frontal cerebral cortex.

In an effort to identify novel binding sites for cocaine and its analogs, we carried out binding studies with the high-affinity and selective ligand [125I]RTI-121 in rat frontal cortical tissue. Very low densities of binding sites were found.…

Pentobarbital differentially inhibits N-methyl-D-aspartate and kainate-stimulated [3H]noradrenaline overflow in rat cortical slices.

1. This study examined the ability of pentobarbital to inhibit NMDA and kainate-stimulated [3H]noradrenaline ([3H]NA) overflow in rat brain cortical slices. 2. Pentobarbital inhibited NMDA-evoked [3H]NA overflow at 100 microM and greater and…

Evaluation of nigrostriatal dopaminergic function in adult +/+ and +/- BDNF mutant mice.

Deletion of a single copy of the BDNF gene has been shown to affect the nigrostriatal dopaminergic system of young adult BDNF mice. In the present report we evaluated various indices of nigrostriatal dopaminergic function between

The effects of intranasal infusion of

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…

Alterations in nigrostriatal dopaminergic function within BDNF mutant mice.

The influence of brain-derived neurotrophic factor (BDNF) upon the nigrostriatal dopaminergic system was evaluated in weanling and adult mice carrying a targeted inactivated BDNF gene. Regional specificity of this BDNF mutation was assessed by…

The effect of estrogen administration in vivo upon catecholamine release in vitro from superfused hypothalamic tissue of ovariectomized pre-pubertal and adult mice.

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…

Methamphetamine-gonadal steroid hormonal interactions: effects upon acute toxicity and striatal dopamine concentrations.

Methamphetamine (MA)-related deaths and nigrostriatal dopaminergic (NSDA) neurotoxicity are greater in males. The exact basis for this gender difference is not known, but data, which show that estrogen (E) can function as a protectant of both the…

Light and electron microscopical immunolocalization of neuropeptide Y-containing nerves in the hamster gallbladder.

Neuropeptide Y (NPY)-containing nerve structures were detected in the Syrian hamster gallbladder by using peroxidase-antiperoxidase immunohistochemical staining and immunoelectron microscopic techniques. In addition, Alcian blue-P.A.S. was used to…

The effects of aging on spinal neurochemistry in the rat.

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…

Castration differentially alters [3H]nisoxetine binding to norepinephrine uptake sites in olfactory bulb and frontal cortex of male rats.

In the present study, [3H]nisoxetine binding to norepinephrine (NE) uptake sites and [3H]norepinephrine uptake were investigated within olfactory bulb (OB) and frontal cortex homogenates from intact and castrated male rats. Statistically significant…

Inactivation of one copy of the mouse neurotrophin-3 gene induces cardiac sympathetic deficits.

Whether two copies of the neurotrophin-3 (NT3) gene are necessary for proper development of cardiac sympathetic innervation was investigated in mice carrying a targeted inactivation of the NT3 gene. Heterozygous (+/-) and null (-/-) mutant mice had…
