Envolvimento de receptores 5-HT1A no hipocampo ventral na regulação de comportamentos defensivos relacionados com a ansiedade generalizada e com o pânico /

Kümpel, Vinícius Dias. January 2016 (has links)
Orientador: Telma Gonçalves Carneiro Spera de Andrade / Banca: Miriam Mendonça Morato Andrade / Banca: Hélio Zangrossi Junior / Resumo: Ainda pouco se conhece a respeito da atividade serotonérgica sobre receptores 5-HT1A no hipocampo ventral na regulação de diferentes tipos de ansiedade. O Labirinto em T elevado (LTE) é um teste que avalia separadamente dois subtipos de ansiedade: a ansiedade generalizada e o pânico, respectivamente através da avaliação dos comportamentos defensivos de esquivas inibitórias e das fugas. Assim, este estudo teve por objetivo investigar o envolvimento de receptores 5-HT1A no HV sobre a manifestação dos transtornos de ansiedade generalizada (TAG) e pânico (TP) no LTE, tendo como parâmetro a ativação de receptores gabaérgicos (GABAA) nessa área do hipocampo. Foram conduzidos dois experimentos em ratos Wistar: o Experimento 1, visando avaliar o efeito do midazolam (10, 20 ou 40nmol) - um benzodiazepínico que potencializa a ação do GABA em receptores GABAA; e o Experimento 2, para avaliar o efeito de 8-OH-DPAT (0,6, 3 ou 15nmol) - um agonista de receptores 5-HT1A. Animais dos grupos controles nos dois experimentos foram tratados com salina. Dez minutos após as microinjeções foram submetidos ao LTE para avaliação das latências (em segundos) para esquivas e fugas. Imediatamente após, os animais foram colocados no centro da arena para avaliação da atividade motora (número de quadrados percorridos). Os resultados apontaram que a maior dose de midazolam microinjetada no hipocampo ventral causou ansiólise, comprovada pela diminuição na latência das esquivas em relação aos animais controle...

The Elevated T Maze (ETM) is a test that evaluates separately two subtypes of anxiety: generalized anxiety and panic, respectively by evaluating the defensive behaviors of inhibitory avoidance and escapes. Therefore this study aimed to investigate the involvement of 5-HT1A receptors in VH on the manifestation of generalized anxiety disorder (GAD) and Panic (PD) in ETM, having as parameter the activation of gabaergic receptors (GABAA) in that area of the hippocampus. Two experiments were conducted in rats: Experiment 1, to evaluate the effect of midazolam (10, 20 or 40nmol) - a benzodiazepine that potentiates the action of the GABA on GABAA receptors; and Experiment 2 to evaluate the effect of 8-OH-DPAT (0.6, 3 or 15nmol) - an agonist of 5-HT1A receptors. Animal control groups in both experiments were treated with saline. Ten minutes after microinjection, the animals were submitted for evaluation to the ETM latencies (in seconds) for avoidances and escapes. Immediately after, the animals were placed in the center of the arena to eavaluation of motor activity (number of covered squares). The results showed that the highest dose of midazolam microinjected in the ventral hippocampus caused anxiolysis, evidenced by the decrease in latency of avoidances compared to controls and those treated animals 10nmol of the same drug.

No. of bitstreams: 1 veridiana costa.pdf: 821261 bytes, checksum: c7ba3ea596fac5b42e3b610d55299d0d (MD5) Previous issue date: 2005-04-08 / The current context presents changes in the subjectives organization ways. Inside this, the redefinitions from the man and woman roles, the new filiation forms, as the new familiar configurations, have brought to a references crisis that reaches different sections from the human life. Among others aspects, this has been implied on redimensionment of the father s place, traditionally conceived as representing from the symbolic law. The father social role is so questioned and, many times, confused with the decline from the paternal function, but, is there is a decline, it is from the patriarchal power, and not of its function, that stays as structural. Fundamental to the structuring of human being and to the social coexistence, the law presents itself like a way of symbolic support. In front of this, we question how stays the reference from the symbolic law, that in the current panorama, it seems leave important blanks in its duties. Inefficient in the limit and interdiction function, the law fails, as well the advantages that should assure of her. No more interdicted, the subject sees himself summoned to the excess and, paradoxally, without references, unsupported. The human condition of unssuporting constituent of the subject due to the life circumstances of people have been exacerbated, what reveals a constant unssuporting situation in which live the nowadays subjects. This leave them to new psychic disorganization forms and makes emerge new symptomatologic configurations, in which expression forms are linked to specific contexts. Among them, the panic disorder highlights as a illustration of the unssuporting more often evocated in the contemporary times, due to the fragility which the law presents itself / O contexto atual apresenta mudanças nos modos de organização subjetiva. Em meio a isso, as redefinições dos papéis do homem e da mulher, as novas formas de filiação, assim como as novas configurações familiares têm levado a uma crise de referências que atinge diferentes setores da vida humana. Dentre outros aspectos, isso tem implicado o redimensionamento do lugar do pai, tradicionalmente concebido como representante da lei simbólica. O papel social do pai passou a ser questionado e, muitas vezes, confundido com o declínio da função paterna, porém, se há um declínio, é do poder do patriarcado, e não de sua função, que permanece como estrutural. Fundamental à estruturação do humano e à convivência social, a lei se apresenta como um modo de amparo simbólico. Diante de tal quadro, questionamos como fica a referência à lei simbólica, que, no panorama atual, parece deixar lacunas importantes em seu exercício. Ineficiente na função de interdição e limite, a lei falha, como falham também as vantagens que ela deveria assegurar. Não mais interditado, o sujeito se vê convocado ao excesso e, paradoxalmente, sem referências, desamparado. A condição humana de desamparo constituinte do sujeito , em razão das circunstâncias de vida das pessoas, vem sendo exacerbada, o que revela a constante situação de desamparo na qual vivem os sujeitos atuais. Isso os leva a novas formas de desorganização psíquica e faz emergir novas configurações sintomatológicas, cujas formas de expressão estão vinculadas a contextos específicos. Dentre elas, o transtorno de pânico se destaca como uma ilustração do desamparo mais freqüentemente evocado na contemporaneidade, promovido pela fragilidade com que a lei se apresenta

No. of bitstreams: 1 dissertacao_georgiana.pdf: 317249 bytes, checksum: 9c7961da3235617b705e4a902ffb1a8d (MD5) Previous issue date: 2008-12-01 / This study aims at analysing the physical symptoms triggered by panic disorder not only its merely physiological reactions but also the way they are psychologically organized, that is to say, the corporal demeanour as viewed by Czermak, When referring to real clinic in Lacan, who privileges the body and its intensities. It is a psychoanalytic research, on which we will use fragments of a clinical case of a 29 year-old young man, married, whose psychiatric diagnosis is Panic Disorder. Our purpose is to search for metapsychological meanings of the revealed physical symptoms. To accomplish this, we will present the meanings expressed by the patient in relation to his corporal symptoms, by means of distinction between such meanings and the physiological manifestations caused by panic, described on the disorder. The corporal representations will be taken as a corporal memory that is revealed oh the transfer. Our aim is to comprehend, with the analysis of the fragments of the studied case, how the corporal demeanour organizes it self psychologically, by means of the interpretation method suggested by psychoanalysis. As theoretical basis for discussion of such issues, we will consider Freud's ideas, according to Basto's view as well as contemporary authors who treat the body in clinic, like Paul Laurent Assoun, Piera Aulagnier, Ivanise Fontes and Maria Helena Fernandes. The analysis of the fragments has indicated that it is possible to identify the organization of the rising subjectiveness throuem body demeanour present in the physical symptoms of panic. / O presente estudo se propõe analisar os sintomas físicos manifestados na Síndrome de Pânico, enfocando-os não como reações fisiológicas, mas como eles se organizaram, psiquicamente, ou seja, como acontecimento corporal no sentido tomado por Czermak, ao referir-se à clínica do real em Lacan, que privilegia o corpo e suas intensidades. Trata-se de uma pesquisa psicanalítica, na qual utilizaremos fragmentos de um caso clínico de um jovem de vinte e nove anos, do sexo masculino, casado, cujo diagnóstico psiquiátrico é de Síndrome de Pânico. Nosso objetivo é buscar as significações metapsicológicas dos sintomas físicos manifestados. Para tanto, apresentaremos as significações dadas pelo paciente aos seus sintomas corporais, distinguindo-as das manifestações fisiológicas desencadeadas pelo pânico, descritas na síndrome. As representações corporais serão entendidas como uma memória corporal que se manifesta na transferência. Nosso propósito é compreender, a partir da análise dos fragmentos deste caso, como se organiza psiquicamente o acontecimento corporal, utilizando o método de interpretação proposto pela psicanálise. Como referencial teórico para discussão de tais questões, tomaremos as contribuições freudianas, pela ótica de Bastos, e também de autores contemporâneos que tratam do corpo na clínica, como Paul-Laurent Assoun, Piera Aulagnier, Ivanise Fontes e Maria Helena Fernandes. A análise dos fragmentos mostrou que é possível identificar, por intermédio do acontecimento de corpo manifesto nos sintomas físicos do pânico, a organização da subjetividade nascente.

Assessing the influence of gastrointestinal symptoms in females with emetophobia : the mere thought of my gut makes me want to vomit

Liebenberg, Anuscha 11 1900 (has links)
The study sought to explore the influence of gastrointestinal symptoms in female respondents with emetophobia disorder, panic disorder with agoraphobia and obsessive compulsive disorder. The research assessed a sample of sixty respondents which formed part of three groups which were recruited from clinical and online support groups. The age ranged from twenty to forty-five years. Non-probability quota sampling was employed. A non-experimental research design was implemented in order to make comparisons between these groups’ association of gastrointestinal symptoms and the occurrence of possible vomiting. The differential research strategy determined whether a statistically significant difference existed. The groups were assessed on the Gastrointestinal Symptom Score (2005) and the Patient Assessment of Upper Gastrointestinal Symptom Severity Index (2004). The research aimed to determine whether empirical support exists for the Cognitive Behavioural Model of Emetophobia by Boschen (2007). / Psychology / M.A. (Psychology)
