In spite of the fact that neurotoxic effects of MDMA has been found in several species from rodents to non-human primates, and results increasingly point to damage also in human MDMA users, data about the sensitivity of different brain areas and the recovery after neuronal damage are scarce. Serotonin transporter (5-HTT) mRNA in the raphe nuclei also has not been examined. Humans with genetic predisposition for the slow metabolism of MDMA, the so-called \u201cpoor metabolizers\u201d of debrisoquin are at higher risk. Five- 9% of the Caucasian population is considered to carry this phenotype. These studies were carried out in Dark Agouti rats, a special strain that show decreased microsomal CYP2D1 isoenzyme activity, and thus may serve as a model of vulnerable human users. These works were designed to characterize MDMA-induced damage and recovery of the serotonergic system including sleep and morphological changes within 180 days. In our experiments we investigated the 5-HTT mRNA expression in the brainstem and medullary raphe nuclei, 5-HTT immunoreactive (IR) fibre densities in several brain areas, and 16 functional measures of sleep in response to a single dose of +\/- MDMA (15mgkg). Furthermore, behavioural experiments were performed 21 days after MDMA treatment. We found similar changes in 5-HTT mRNA expression in the examined raphe nuclei, namely transient increases 7 days after MDMA treatment followed by transient decreases at 21 days. Significant (20\u201340%), widespread reductions in 5-HTT-IR fibre density were detected in most brain areas at 7 and 21 days after MDMA administration. All cortical, but only some brainstem areas were damaged. Parallel to the neuronal damage we observed significant reductions in rapid eye movement (REM) sleep latency, increased fragmentation of sleep and increases in delta power spectra in non-REM sleep. At 180 days almost all functional changes in sleep were normalized together with 5-HTT mRNA expression in the examined raphe nuclei and the recovery of 5-HTT-IR fibre density in most brain areas. Our results also suggest that the acute MDMA administration abolished aggressive behaviour but MDMA pretreatment and the consequent depletion of serotonergic terminals did not affect aggression. Our findings concerning the changes detected in 5-HTT mRNA expression and fibre density indicate lasting impairment of the serotonergic system and suggest that a single use of MDMA may be associated with long-lasting cognitive, learning, memory and mood deficits and sleep disturbances particularly when a constellation of genetic vulnerability and certain environmental factors are present. Our data provide further evidence for the connection between altered serotonergic functions and sleep disturbance.<\/p>\n<p><strong>Keywords:<\/strong>\u00a0MDMA, serotonin transporter, raphe nucleus, REM latency, aggression<\/p>\n<\/div>\n<p>[\/et_pb_toggle][et_pb_blurb title=&#8221;9-hydroxy-risperidone (9OHRIS) prevents stress-induced \u00df-actin overexpression in rat hippocampus&#8221; url=&#8221;https:\/\/mppt.hu\/magazin\/pdf\/xii-evfolyam-3-szam\/kalman_web_20101018.pdf&#8221; url_new_window=&#8221;on&#8221; image=&#8221;https:\/\/mppt.hu\/wp-content\/uploads\/2019\/04\/pdf.png&#8221; icon_placement=&#8221;left&#8221; image_max_width=&#8221;105%&#8221; content_max_width=&#8221;1100px&#8221; _builder_version=&#8221;3.22.7&#8243; header_font=&#8221;||||||||&#8221; header_font_size=&#8221;17px&#8221; header_line_height=&#8221;1.3em&#8221; body_font=&#8221;||on||||||&#8221; body_line_height=&#8221;1.3em&#8221; link_option_url=&#8221;https:\/\/mppt.hu\/magazin\/pdf\/xii-evfolyam-3-szam\/kalman_web_20101018.pdf&#8221; link_option_url_new_window=&#8221;on&#8221;]<\/p>\n<p>S\u00e1ra<sup>\u00a0<\/sup>K\u00e1lm\u00e1n, Magdolna<sup>\u00a0<\/sup>P\u00e1k\u00e1ski, Szabina<sup>\u00a0<\/sup>Sz\u0171cs, J\u00e1nos ifj.<sup>\u00a0<\/sup>K\u00e1lm\u00e1n , \u00d6rsike<sup>\u00a0<\/sup>Fazekas, Petra<sup>\u00a0<\/sup>S\u00e1ntha, Gyula<sup>\u00a0<\/sup>Szab\u00f3, Zolt\u00e1n<sup>\u00a0<\/sup>Janka and J\u00e1nos<sup>\u00a0<\/sup>K\u00e1lm\u00e1n<\/p>\n<p>[\/et_pb_blurb][et_pb_toggle title=&#8221;Abstract&#8221; closed_toggle_text_color=&#8221;#000000&#8243; closed_toggle_background_color=&#8221;rgba(0,0,0,0)&#8221; icon_color=&#8221;#0c71c3&#8243; _builder_version=&#8221;3.22.7&#8243; title_font=&#8221;|600|||||||&#8221; title_letter_spacing=&#8221;1px&#8221; text_orientation=&#8221;justified&#8221; custom_padding=&#8221;0px||10px&#8221; border_width_all=&#8221;0px&#8221; border_width_bottom=&#8221;1px&#8221;]<\/p>\n<div class=\"artbody\">\n<p>Alzheimer\u2019s disease (AD) is the most frequent form of neurodegenerative dementias.<br \/>The aetiology and the exact pathomechanism of AD is not known, but stress has been<br \/>considered recently in the aetiology. Beside the abnormal metabolism of the amyloid<br \/>\u2013 precursor protein (APP), the hyperactivity of the mitogen \u2013 activated protein kinase 1<br \/>(MAPK1) involved in the hyperphosphorylation of the tau proteins \u2013 which are considered<br \/>as the major component of neurofibrillary tangles \u2013, in addition to \u00df-actin, being involved<br \/>in synaptogenesis and neuronal plasticity, are all considered as important contributors of<br \/>the development of AD specific neuropathological changes. The major aim of our present<br \/>investigation was to examine the effect of stress on the expression of APP, MAPK1 and<br \/>\u00df-actin mRNAs in the rat hippocampus and cortex. The effect of 9-hydroxy-risperidone<br \/>(9OHRIS) on the transcription of these genes was also examined. Adult, male Wistar rats<br \/>were exposed to chronic immobilization stress for 3 weeks. The 9OHRIS (4 mg\/bwkg)<br \/>was administred by gastric tube. Four groups were formed depending on the treatment:<br \/>(1) control, (2) stress, (3) 9OHRIS, (4) stress and parallel 9OHRIS treatment (n=5-6). The<br \/>expression of APP, MAPK1, \u00df-actin mRNAs from the perfused brain samples was measured<br \/>with real-time PCR technique. The \u00df-actin mRNA was significantly overexpressed in the<br \/>hippocampus after 3 weeks of stress treatment. On the other hand, the stress induced<br \/>hippocampal \u00df-actin mRNA overexpression was repressed by the 9OHRIS treatment.<br \/>There were no changes in the cortical or hippocampal expression of APP and MAPK1<br \/>mRNAs after neither the stress nor the 9OHRIS treatments. These results emphasize<br \/>the importance of the stress induced \u00df-actin expression in rat hippocampus. The stress<br \/>induced alterations in the \u00df-actin RNA expression could be associated with neuronal<br \/>plasticity and adaptional processes, which could be modified by the 9OHRIS treatment.<br \/>Our findings indicate that a second generation antipsychotic drug could have a beneficial<br \/>effect in the pathomechanism of stress and this may have relevance in the treatment of<br \/>such devastating conditions like AD and psychotic disorders.<\/p>\n<p><strong>Keywords<\/strong>: Alzheimer\u2019s disease, stress, hippocampus, amyloid-precursor protein,<br \/>mitogen-activated protein kinase, \u00df-actin, 9-hydroxy-risperidone, real-time PCR<\/p>\n<\/div>\n<p>[\/et_pb_toggle][et_pb_blurb title=&#8221;Application of lamotrigine in bipolar disorder \u2013 3T MR spectroscopy follow up (part 1)&#8221; url=&#8221;https:\/\/mppt.hu\/magazin\/pdf\/xii-evfolyam-3-szam\/sumegi_esettan_web_20101018.pdf&#8221; url_new_window=&#8221;on&#8221; image=&#8221;https:\/\/mppt.hu\/wp-content\/uploads\/2019\/04\/pdf.png&#8221; icon_placement=&#8221;left&#8221; image_max_width=&#8221;105%&#8221; content_max_width=&#8221;1100px&#8221; _builder_version=&#8221;3.22.7&#8243; header_font=&#8221;||||||||&#8221; header_font_size=&#8221;17px&#8221; header_line_height=&#8221;1.3em&#8221; body_font=&#8221;||on||||||&#8221; body_line_height=&#8221;1.3em&#8221; link_option_url=&#8221;https:\/\/mppt.hu\/magazin\/pdf\/xii-evfolyam-3-szam\/sumegi_esettan_web_20101018.pdf&#8221; link_option_url_new_window=&#8221;on&#8221;]<\/p>\n<p>Andr\u00e1s<sup>\u00a0<\/sup>S\u00fcmegi, Szabolcs Hal\u00e1sz and Edit<sup>\u00a0<\/sup>Kliment<\/p>\n<p>[\/et_pb_blurb][et_pb_toggle title=&#8221;Abstract&#8221; closed_toggle_text_color=&#8221;#000000&#8243; closed_toggle_background_color=&#8221;rgba(0,0,0,0)&#8221; icon_color=&#8221;#0c71c3&#8243; _builder_version=&#8221;3.22.7&#8243; title_font=&#8221;|600|||||||&#8221; title_letter_spacing=&#8221;1px&#8221; text_orientation=&#8221;justified&#8221; custom_padding=&#8221;0px||10px&#8221; border_width_all=&#8221;0px&#8221; border_width_bottom=&#8221;1px&#8221;]<\/p>\n<div class=\"autors\">\n<p>MR spectroscopy (MRS) is a widely used and useful additional tool in the diagnostic<br \/>process of several neuropsychiatric disorders. Despite several MRS studies in bipolar<br \/>spectrum reserach, establishing a clean image about special metabolite alterations in<br \/>the disorder still needs further investigation. The first part of this case study presents a<br \/>bipolar II patient and her first 3T MR spectroscopy in drug-naive conditions, comparing<br \/>to a healthy subject. Having finished the first MRS investigation, we applied lamotrigine<br \/>medication.
