Aromaterapia e Ansiedade: revisão integrativa da literatura

This study aimed at investigating, in the national and international scientific literature, how aromatherapy is used as a therapeutic tool to reduce anxiety. It is a bibliographic study that adopted integrative literature review as a method. Studies published on databases Scielo, Medline and Cinahl from 2008 to 2012 were selected. A sample of 20 scientific articles was analyzed, and of these, 13 had an experimental and a quasi--experimental design whereas 07 were systematic or integrative reviews. The synthesis of knowledge sho-wed that aromatherapy represents a safe therapeutic practice although it is still underestimated in health care practices. The construction of evidence levels was not possible due to discrepancies in the studied populations, in research designs, the various essential oils used and the different methods for aromatherapy application. The knowledge gaps identified in these studies are related to the need to develop new forms to evaluate the effectiveness of this practice, including the therapist-patient relationship and the different communication forms that are intrinsic to aromatherapy.

Efeitos do treinamento aeróbio e de força sobre a área de secção transversal (AST) das fibras do músculo plantar de ratos

Recent research seeking to elucidate the possible effects of different types of physical training on the morphological adaptations of skeletal muscle. Although it is relatively easy to study the effects of exercise training in humans, such research becomes limited due to the invasive nature of the biopsies and the risk inherent in the use of human subjects. Thus, the application of animal models of training has been considered an appropriate strategy for the study of muscular adaptations in response to exercise. Objective: This study used a rodent model to determine the possible effects of aerobic and strength training on the CSA of fibers of the plantaris muscle. Methods: 24 male Wistar rats (80 to 120 days, 250 to 400 g) were randomly divided into 3 groups: aerobic training (TA, n = 8), strength training (ST, n = 8) and control (CO, n = 8). The animals in groups TA and TF were subjected to 8 weeks of training, while the animals of group C remained without any stimulus from start to finish the training period. At the end of the experiment, the animals were sacrificed and right plantar muscles dissected and removed. For morphological and morphometric analysis of muscle fibers was performed staining was performed H.E. Results: There was no significant difference in initial body weight between experimental groups. After 8 weeks of training, the TA group showed a significant reduction in final body weight, compared to CO and TF groups. With respect to the CSA of fibers of the plantaris muscle, no significant difference between the groups CO and TA. On the other hand, the strength training promoted a significant increase in AST of the group TF in compared with the groups CO and TA. Conclusion: Strength training used in this study promoted an increase in CSA of fibers of the plantaris muscle. On the other hand, animals submitted to aerobic training showed no changes in the CSA of the fibers, however, there was reduction in PC animals. The data strongly suggest the use of animal model of strength training used in this study as an appropriate strategy for studying the hypertrophic response of skeletal muscle.

Sensibilização comportamental ao etanol e neuroadaptações envolvendo a proteína (DELTA)FOSB: efeitos do tratamento com N-Acetilcisteína em camundongos

Pharmacological treatments currently used in ethanol addiction are inefficient, requiring new drugs for this purpose. The pro-drug N-Acetylcysteine (N-Ac) has shown efficacy in the treatment of addiction to cocaine and nicotine in preclinical research and clinical pilot studies. When administered, N-Ac is subsequently converted to cysteine, and cystine, which has an action on the central nervous system. However, there are few data about the possible application of N-Ac in the ethanol addiction. Behavioral sensitization is the gradual increase of the psychostimulant effects induced by repeated administration of drugs of abuse, including ethanol, and its development has been linked to important neuroadaptations in addiction. These neuroadaptations occur in neural circuits that mediate the reinforcing properties of these drugs and may involve several proteins. The ΔFosB protein accumulates in neurons after repeated activation and mediates long lasting changes in response to drugs of abuse. These changes are manifested mainly in the nucleus accumbens (Acb) and prefrontal cortex (PFC) neurons. The aim of the study was to evaluate the effects of N-Ac treatment in the development of ethanol behavioral sensitization and in alterations in the ΔFosB protein in mice. Swiss male mice were exposed to a standardized behavioral sensitization protocol to the experimental conditions of the laboratory and treated with N-Ac. At the end of behavioral sensitization procedure, animals were euthanized and their brains removed for ΔFosB quantification by Western blotting. Two experiments of behavioral sensitization were performed to the standardization of the protocol. The first, although effective in demonstrating the development of behavioral sensitization, was not effective in allowing the evaluation of the expression of the behavioral sensitization. The age of the animals and the conditions of luminosity and color of locomotion apparatus were changed and a new...

Efeitos de histórias experimentais e de justificativas sociais sobre o comportamento de seguir regras

Este estudo avaliou o efeito de justificativas sobre o comportamento de seguir regras, quando foi construída uma história de reforço para não seguir regra. Dez crianças foram expostas a um procedimento de escolha segundo o modelo, cuja tarefa era tocar um de dois estímulos de comparação na presença de um estímulo contextual. Nas Condições I e II, as Fases 1, 2 e 4 eram iniciadas com a apresentação de instruções discrepantes das contingências programadas, cujo comportamento de segui-las produzia perda de fichas. Na Fase 3 era apresentada uma instrução correspondente com uma justificativa para seguir a instrução que produzia perda de fichas. A Condição I diferia da Condição II apenas com relação ao tipo de justificativa apresentada na Fase 3. Na Condição I era apresentada uma justificativa para ajudar crianças carentes e na Condição II uma justificativa que envolvia a aprovação do experimentador. O comportamento de nove dos 10 participantes ficou sob o controle da história de reforço para o não seguir instrução e das consequências imediatas produzidas pelo comportamento de não seguir instruções; o comportamento de um participante ficou sob o controle da justificativa para seguir a instrução correspondente.
