Despite their prevalence and spectrum of functions, appreciation of their potential general importance has been elusive since their identification in the mids, and only relatively recently have they been gaining their due respect.
Neuroimmune basis of methamphetamine toxicity. International Review of Neurobiology. Collectively, these pathological processes contribute to neurotoxicity e.
Curr Neuropharmacol. They are present in the organs that mediate the actions of METH e. In the brain, METH acts primarily on the dopaminergic system to cause acute locomotor stimulant, subchronic sensitized, and neurotoxic effects.

Despite the importance of numerous psychosocial factors, at its core, drug addiction involves a biological process: the ability of repeated exposure to a drug of abuse to induce changes in a vulnerable brain that drive the compulsive seeking and taking of drugs, and loss of control over drug use, that define a state of addiction.
Moreover, there is increasing evidence that, despite a range of genetic risks for addiction across the population, exposure to sufficiently high doses of a drug for long periods of time can transform someone who has relatively lower genetic loading into an addict.
Mount Sinai School of Medicine. Department of Neuroscience. Retrieved 9 February New England Journal of Medicine. Substance-use disorder: A diagnostic term in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders DSM-5 referring to recurrent use of alcohol or other drugs that causes clinically and functionally significant impairment, such as health problems, disability, and failure to meet major responsibilities at work, school, or home.
Depending on the level of severity, this disorder is classified as mild, moderate, or severe. Addiction: A term used to indicate the most severe, chronic stage of substance-use disorder, in which there is a substantial loss of self-control, as indicated by compulsive drug taking despite the desire to stop taking the drug.
In the DSM-5, the term addiction is synonymous with the classification of severe substance-use disorder. This is known to occur on many genes including fosB and c-fos in response to psychostimulant exposure.
Chronic exposure to psychostimulants increases glutamatergic [signaling] from the prefrontal cortex to the NAc.
The Journal of General Physiology. Coincident and convergent input often induces plasticity on a postsynaptic neuron. The NAc integrates processed information about the environment from basolateral amygdala, hippocampus, and prefrontal cortex PFC , as well as projections from midbrain dopamine neurons.
Previous studies have demonstrated how dopamine modulates this integrative process. For example, high frequency stimulation potentiates hippocampal inputs to the NAc while simultaneously depressing PFC synapses Goto and Grace, KEGG Pathway.
Retrieved 31 October Most addictive drugs increase extracellular concentrations of dopamine DA in nucleus accumbens NAc and medial prefrontal cortex mPFC , projection areas of mesocorticolimbic DA neurons and key components of the "brain reward circuit".
Amphetamine achieves this elevation in extracellular levels of DA by promoting efflux from synaptic terminals.
Chronic exposure to amphetamine induces a unique transcription factor delta FosB, which plays an essential role in long-term adaptive changes in the brain.
Molecular Neurobiology. Nature Reviews Neuroscience. The net result is gene activation and increased CDK5 expression. The net result is c-fos gene repression.
Clinical Psychopharmacology and Neuroscience. Drug Alcohol Abuse. Similar to environmental enrichment, studies have found that exercise reduces self-administration and relapse to drugs of abuse Cosgrove et al.
There is also some evidence that these preclinical findings translate to human populations, as exercise reduces withdrawal symptoms and relapse in abstinent smokers Daniel et al.
In humans, the role of dopamine signaling in incentive-sensitization processes has recently been highlighted by the observation of a dopamine dysregulation syndrome in some patients taking dopaminergic drugs.
This syndrome is characterized by a medication-induced increase in or compulsive engagement in non-drug rewards such as gambling, shopping, or sex Evans et al.
Archived from the original on 13 October Bibcode : PNAS.. Journal of Psychoactive Drugs. It has been found that deltaFosB gene in the NAc is critical for reinforcing effects of sexual reward.
Pitchers and colleagues reported that sexual experience was shown to cause DeltaFosB accumulation in several limbic brain regions including the NAc, medial pre-frontal cortex, VTA, caudate, and putamen, but not the medial preoptic nucleus.
Drugs of abuse induce neuroplasticity in the natural reward pathway, specifically the nucleus accumbens NAc , thereby causing development and expression of addictive behavior.
Sexual behavior is highly rewarding Tenk et al. Moreover, sexual experience induces neural plasticity in the NAc similar to that induced by psychostimulant exposure, including increased dendritic spine density Meisel and Mullins, ; Pitchers et al.
Finally, periods of abstinence from sexual experience were found to be critical for enhanced Amph reward, NAc spinogenesis Pitchers et al. Drug Alcohol Depend.

Shoptaw SJ, Ali R eds. A minority of individuals who use amphetamines develop full-blown psychosis requiring care at emergency departments or psychiatric hospitals.
In such cases, symptoms of amphetamine psychosis commonly include paranoid and persecutory delusions as well as auditory and visual hallucinations in the presence of extreme agitation.
Findings from one trial indicate use of antipsychotic medications effectively resolves symptoms of acute amphetamine psychosis.

AMPH and METH also stimulate DA efflux, which is thought to be a crucial element in their addictive properties [80], although the mechanisms do not appear to be identical for each drug [81].
University of Paris. Archived from the original on 29 May Retrieved 29 May Retrieved 5 October Methamphetamine is rapidly absorbed from the gastrointestinal tract with peak methamphetamine concentrations occurring in 3.
Methamphetamine is also well absorbed following inhalation and following intranasal administration. It is distributed to most parts of the body.
Because methamphetamine has a high lipophilicity it is distributed across the blood brain barrier and crosses the placenta.
The primary site of metabolism is in the liver by aromatic hydroxylation, N-dealkylation and deamination. At least seven metabolites have been identified in the urine, with the main metabolites being amphetamine active and 4-hydroxymethamphetamine.
Other minor metabolites include 4-hydroxyamphetamine, norephedrine, and 4-hydroxynorephedrine. Foye's principles of medicinal chemistry 7th ed. The simplest unsubstituted phenylisopropylamine, 1-phenylaminopropane, or amphetamine, serves as a common structural template for hallucinogens and psychostimulants.
Amphetamine produces central stimulant, anorectic, and sympathomimetic actions, and it is the prototype member of this class The phase 1 metabolism of amphetamine analogs is catalyzed by two systems: cytochrome P and flavin monooxygenase.
Amphetamine can also undergo aromatic hydroxylation to p -hydroxyamphetamine. Stereochemical course of the reaction" PDF.
Archived PDF from the original on 7 October Retrieved 6 November Hydroxyamphetamine was administered orally to five human subjects The lack of effect of administration of neomycin to one patient indicates that the hydroxylation occurs in body tissues.
Unfortunately, at the present time one cannot be completely certain that the hydroxylation of hydroxyamphetamine in vivo is accomplished by the same enzyme which converts dopamine to noradrenaline.

Im Vertrauen gesagt ist meiner Meinung danach offenbar. Sie versuchten nicht, in google.com zu suchen?
Es ist die ausgezeichnete Idee
Ich denke, dass Sie sich irren. Geben Sie wir werden besprechen. Schreiben Sie mir in PM.
Wacker, mir scheint es, es ist die ausgezeichnete Phrase
Wirklich?
