The influence of 1,3-dimethyl-5-adamantanamine (D-145) on catecholaminergic neurons of the rat brain, Histofluorescence studies. 1976

M Smialowska

The effect of a compound stimulating central dopaminergic structures, 1,3-dimethyl-5-adamantanamine (D-145), on the intensity of fluorescence in catecholaminergic nerve endings in some regions of the rat brain, mainly in the striatum and hypothalamus, was investigated with the modificated histofluorescence technique of Falck and Hillarp. D-145 (20 mg/kg), 2-3 hr after the administration depressed the intensity of catecholamine (CA) fluorescence in caudate-putamen (CP) and hypothalamic paraventricular nucleus (PVH). A blockade of dopamine (DA) receptors with spiperone (SPIRO, 2 mg/kg, 5 min before D-145) abolished the D-145 effect in PVH, thus indicating an indirect effect of D-145 on PVH, via a dopaminergic system. D-145 potentiated the depression of CA fluorescence produced by alpha-methyl-tyrosine methyl ester (H 44/68), 250 mg/kg ip. High doses of the CA synthesis inhibitor (2 X 400 mg/kg ip) prevented the developing of stimulation produced by D-145. These data indicate that the action of D-145 on DA receptors is indirect, via endogenous DA.

D009474	Neurons	The basic cellular units of nervous tissue. Each neuron consists of a body, an axon, and dendrites. Their purpose is to receive, conduct, and transmit impulses in the NERVOUS SYSTEM.	Nerve Cells,Cell, Nerve,Cells, Nerve,Nerve Cell,Neuron
D001921	Brain	The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.	Encephalon

D003864	Depression, Chemical	The decrease in a measurable parameter of a PHYSIOLOGICAL PROCESS, including cellular, microbial, and plant; immunological, cardiovascular, respiratory, reproductive, urinary, digestive, neural, musculoskeletal, ocular, and skin physiological processes; or METABOLIC PROCESS, including enzymatic and other pharmacological processes, by a drug or other chemical.	Chemical Depression,Chemical Depressions,Depressions, Chemical
D005453	Fluorescence	The property of emitting radiation while being irradiated. The radiation emitted is usually of longer wavelength than that incident or absorbed, e.g., a substance can be irradiated with invisible radiation and emit visible light. X-ray fluorescence is used in diagnosis.
D006651	Histocytochemistry	Study of intracellular distribution of chemicals, reaction sites, enzymes, etc., by means of staining reactions, radioactive isotope uptake, selective metal distribution in electron microscopy, or other methods.	Cytochemistry
D000547	Amantadine	An antiviral that is used in the prophylactic or symptomatic treatment of influenza A. It is also used as an antiparkinsonian agent, to treat extrapyramidal reactions, and for postherpetic neuralgia. The mechanisms of its effects in movement disorders are not well understood but probably reflect an increase in synthesis and release of dopamine, with perhaps some inhibition of dopamine uptake.	1-Aminoadamantane,Adamantylamine,Adekin,Aman,Amanta,Amanta-HCI-AZU,Amanta-Sulfate-AZU,Amantadin AL,Amantadin AZU,Amantadin Stada,Amantadin-neuraxpharm,Amantadin-ratiopharm,Amantadina Juventus,Amantadina Llorente,Amantadine Hydrochloride,Amantadine Sulfate,Amixx,Cerebramed,Endantadine,Gen-Amantadine,Infecto-Flu,Infex,Mantadix,Midantan,PMS-Amantadine,Symadine,Symmetrel,Viregyt,Wiregyt,tregor,1 Aminoadamantane,AL, Amantadin,AZU, Amantadin,Amanta HCI AZU,Amanta Sulfate AZU,AmantaHCIAZU,AmantaSulfateAZU,Amantadin neuraxpharm,Amantadin ratiopharm,Amantadinneuraxpharm,Amantadinratiopharm,Gen Amantadine,GenAmantadine,Hydrochloride, Amantadine,Infecto Flu,InfectoFlu,Juventus, Amantadina,Llorente, Amantadina,PMS Amantadine,PMSAmantadine,Stada, Amantadin,Sulfate, Amantadine
