This book was released on 2010 with total page 324 pages. Available in PDF, EPUB and Kindle. Book excerpt: 3,4-Methylenedioxymethamphetamine (MDMA, 'ecstasy') is an amphetamine derivative widely used in rave party and club scenes. In some users, MDMA causes fatalities, most often due to acute hyperthermia which leads eventually to multi-organ failure. Other structurally related drugs, including methamphetamine and para-methoxyamphetamine (PMA), as well as structurally unrelated cocaine, have also been associated with death due to hyperthermia, and are also often taken with or instead of MDMA. Harm minimisation advice to prevent this acute hyperthermia depends on appropriate thermoregulatory behaviour by drug users, an aspect of thermoregulation which had not been studied with respect to MDMA previously. The purpose of this thesis was to use a novel behavioural thermoregulation model in rats to investigate the effects of MDMA and other stimulant drugs on behavioural thermoregulation and related physiological parameters, as well as investigating residual neurochemical changes caused by these substances. The behavioural thermoregulation model used throughout most of this thesis involved rats being administered a drug, immediately prior to being confined to a set ambient temperature (30 ± 1o or 21.5 ± 1.5oC) for 30 minutes. Rats were then immediately allowed access to a thermally graded runway (11-41oC) where they were able to choose their preferred temperature for a further 4 hours. The final study consisted of giving rats a drug in their home cages at an elevated ambient temperature. Firstly, a dose-response study was conducted using MDMA, PMA, methamphetamine and cocaine. All drugs lead to a dose dependent increase in core temperature at high ambient temperature, and this led to animals seeking the cool end of the runway after MDMA, methamphetamine and cocaine administration, but not after PMA. Methamphetamine was the most potent drug at increasing core temperature, followed by MDMA and PMA, then cocaine as the least potent, however, MDMA and PMA showed steeper slopes on the dose-response curves than methamphetamine and cocaine. The second study consisted of rats receiving MDMA at 30 or 21.5oC for three consecutive days a week for one week or 6 weeks before being tested in the thermal gradient. The main findings of this study were that heart rate (HR) response to MDMA progressively decreased with repeated dosing over 6 weeks at both ambient temperatures, and that there was a difference in core temperature between rats treated for 6 weeks compared to 1 week when they were in the thermal gradient. The third study looked at the effects of MDMA in an animal model of depression, the Flinders Sensitive Line (FSL) rat. We showed that FSL rats were much more sensitive to the effects of MDMA at a high ambient temperature compared to Sprague-Dawley controls, however there were limited differences in behaviour in the thermal gradient between the strains. Pharmacokinetic analysis showed that there was no difference in blood or brain concentrations of MDMA, or its metabolite 3,4-methylenedioxyamphetamine (MDA) which could have explained the different responses. These concentrations also showed that the dosing regimens used throughout this thesis led to similar plasma concentration as those reported in human users. The final study was a pilot study done to see if proteomics could be a useful method to investigate the effects of MDMA and other stimulants on the brain after administration at a high ambient temperature. Rats were administered MDMA, methamphetamine or a combination, and several changes in protein expression were found. These were mostly evident in rats treated with MDMA which was in contrast to the effects on neurotransmitter concentration and acute hyperthermia, which was only seen in rats treated with MDMA and methamphetamine together. Three of the four results chapters in this thesis have been published or have been accepted for publication, while the fourth has been prepared as a manuscript ready for publication.
Download or read book Effects of Auditory and Thermal Stimuli on 3 4 Methylenedioxymethamphetamine MDMA induced Neurochemical and Behavioral Responses written by Allison Anne Feduccia and published by . This book was released on 2009 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: The amphetamine derivative, 3,4-methylenedioxymethamphetamine (MDMA), is a popular drug often taken by young adults at dance clubs or rave parties. Laser light shows, fast-paced electronic music, and hot crowded dance floors are characteristic of these events, and Ecstasy users report that the acute effects of the drug are potentiated by these stimulatory conditions. However, it remains largely unknown how environmental stimuli impact the neurochemical and physiological effects of MDMA. The aim of the first study presented in this dissertation was to investigate how auditory stimuli (music, white noise, and no additional sound) influence MDMA conditioned place preference (CPP), self-administration, and nucleus accumbens (NAcc) dopamine (DA) and serotonin (5-HT) responses. Findings revealed a significant CPP for animals exposed to white noise during MDMA conditioning trials. After self-administration of MDMA (1.5 mg/kg), NAcc DA and 5-HT were highest in rats exposed to music during the test session. The second study aimed to investigate the effects of ambient temperature (23° or 32°C) on long-term MDMA self-administration and neurochemical responses. Results indicated no difference in self-administration or locomotor activity rates for the high versus room temperature groups across sessions. However, MDMA (3.0 mg/kg) administered in high ambient temperature resulted in significantly greater NAcc serotonin release compared to when taken at room temperature, but no differences in dopamine response was determined between the two conditions. Overall, these results indicate that auditory and thermal stimuli can effect MDMA-induced behavioral and neurochemical responses. The last aim tested a novel apparatus and method for use in animal models of drug reinforcement. By combining traditional CPP and self-administration procedures, this approach provided more informative data and circumvented some inherent drawbacks of each method alone. In addition to confirming the ability to produce drug conditioned place preferences after short- and long-term experiments, the long-term version of the procedure revealed a significant positive relationship between lever response rate and CPP magnitude. Therefore, this experimental design can be used to identify subgroups of rats that may vary in sensitivity to drug motivational effects. Further study of these populations may be useful in the development of behavioral and pharmacological therapies for drug addiction.

Download or read book Synthetic Cathinones written by Jolanta B. Zawilska and published by Springer. This book was released on 2018-04-16 with total page 215 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last decade, and particularly during the recent five years, a rapidly increasing number of novel psychoactive substance (NPSs), often marketed as “designer drugs”, “legal highs”, “herbal highs”, “research or intermediate chemicals” and “laboratory reagents”, has appeared on the drug market in an effort to bypass controlled substance legislation. NPSs encompass a wide range of different compounds and drug classes but had been dominated by synthetic cannabinomimetics and psychostimulatory synthetic cathinones, so-called β-keto amphetamines. Compounds from the later class were first detected in Europe in 2004, and since then 103 new cathinones have been identified and reported to the European Monitoring Centre for Drugs and Drug Addiction, with 57 during the last two years. Synthetic cathinones – novel addictive and stimulatory psychoactive substances is the first publication of this kind that provides readers with background on chemical structures, detection, prevalence and motivation of use of the very popular group of NPSs. This book also presents comprehensive overview of the mechanisms of action, pharmacological activity, and main metabolic pathways of synthetic cathinones, followed by a detailed discussion of the acute and chronic toxicity associated with the use of these substances. Written by international experts in the field, this multi-authored book is a valuable reference not only for scientists, clinicians and academics, but also for readers representing different professional background who are involved in educational-prophylactic activities directed to harm reduction of psychoactive compounds.
