RESUMO
Introdução: O tabagismo é capaz de causar intoxicação química desencadeando efeitos deletérios de natureza aguda ou crônica em diversas estruturas do corpo, afetando significativamente a saúde. É considerada uma epidemia que mais ameaça à saúde pública em todo o mundo. Objetivo: Para tanto, esse estudo objetiva-se analisar o grau de dependência, a história tabágica, a caracterização sociodemográfica a adesão terapêutica dos usuários em tratamento de cessação do tabagismo atendidos pela rede CAPS-AD em um município do interior do Ceará. Métodos: Trata-se de um estudo quantitativo e descritivo. Foi desenvolvido por meio de reuniões coletivas com o grupo de cessação tabágica, os usuários foram convidados a participar da pesquisa, respeitando o princípio da autonomia, após apresentação dos objetivos e esclarecimentos a cerda do estudo. Resultados: Foram recrutados 19 usuários em tratamento de cessação tabágica. Desses, 10 participantes eram do sexo masculino e 9 ao sexo feminino. Com relação a faixa etária, 42,11% estavam entre as idades de 46 a 55 anos e a maioria dos participantes não tinha o ensino fundamental completo e eram civilmente casados. Analisando o IMC, 57,9% estavam com peso normal e 21,05% com sobrepeso. Mais de 80% iniciaram o vício na adolescência e68% relataram não conviver com fumantes em casa. Em relação à adesão terapêutica, cerca de 52% foram satisfatórias. Conclusão: De um modo geral observa-se que a população do estudo, tem um elevado índice de dependência à nicotina em decorrência do prolongado tempo de uso, do início precoce e de uma procura de tratamento tardia.
Introduction: Smoking is able to cause chemical intoxication triggering deleterious effects of acute or chronic nature in several structures of the body, significantly affecting health. It is considered an epidemic that most threatens public health worldwide. Objective: Therefore, this study aimed to analyze the degree of dependence, smoking history, sociodemographic characterization, and therapeutic adherence of users in smoking cessation treatment assisted by the CAPS-AD network in a city in the interior of Ceará. Methods: This is a quantitative and descriptive study. It was developed through collective meetings with the smoking cessation group, users were invited to participate in the research, respecting the principle of autonomy, after presentation of the objectives and clarifications about the study. Results: Nineteen users in smoking cessation treatment were recruited. Of these, 10 participants were male and 9 were female. Regarding the age range, 42.11% were between 46 and 55 years old, and most participants did not have complete elementary school education and were civilly married. Analyzing the BMI, 57.9% were normal weight and 21.05% were overweight. More than 80% started smoking during adolescence and 68% reported not living with smokers at home. In relation to therapeutic adherence, about 52% were satisfactory. Conclusion: In general, it is observed that the study population has a high rate of nicotine dependence due to the prolonged time of use, the early onset and a late search for treatment.

Conclusión: En general se observa que la población de estudio, presenta una alta tasa de dependencia nicotínica debido al tiempo prolongado de consumo, inicio precoz y demanda tardía de tratamiento.
RESUMO
Depression is a common disease affecting more than 300 million people worldwide. Since Lippia sidoides has shown central nervous system effects in previous works, we aimed to investigate the effect of L. sidoides essential oil and its major compound, thymol on a corticosterone-induced depression model in mice. Male mice (20â»25 g) received corticosterone (20 mg/kg, subcutaneously), once a day for 22 days. From the 16th day on, mice were grouped to receive either corticosterone or L. sidoides essential oil (100 and 200 mg/kg), or thymol (25 and 50 mg/kg) or fluoxetine (35 mg/kg) by gavage. The forced swimming test, tail suspension, open field, elevated plus maze and sucrose preference tests were performed from the 19th to 22nd day. Data were analyzed by ANOVA followed by the Student-Newman-Keuls as a post hoc test and the results were considered significant when p < 0.05. It was shown that L. sidoides essential oil, thymol and fluoxetine decreased the immobility time in the tail suspension and forced swimming tests and none of these altered locomotor activity in the open field test. However, the drugs increased the amount of grooming. In the elevated plus maze, all drugs increased the number of entries and the time of permanence in the open arms. In the sucrose preference test, the L. sidoides essential oil, thymol and fluoxetine reversed anhedonia. These results suggest that the thymol and L. sidoides essential oil have an antidepressant-like effect, similar to fluoxetine. However, future studies should be encouraged to enhance understanding of the effects of essential oil and thymol for the treatment of depression.
RESUMO
Background. Omega-3 (ω3) administration was shown to protect against hypoxic-ischemic injury. The objectives were to study the neuroprotective effects of ω3, in a model of global ischemia. Methods. Male Wistar rats were subjected to carotid occlusion (30 min), followed by reperfusion. The groups were SO, untreated ischemic and ischemic treated rats with ω3 (5 and 10 mg/kg, 7 days). The SO and untreated ischemic animals were orally treated with 1% cremophor and, 1 h after the last administration, they were behaviorally tested and euthanized for neurochemical (DA, DOPAC, and NE determinations), histological (Fluoro jade staining), and immunohistochemical (TNF-alpha, COX-2 and iNOS) evaluations. The data were analyzed by ANOVA and Newman-Keuls as the post hoc test. Results. Ischemia increased the locomotor activity and rearing behavior that were partly reversed by ω3. Ischemia decreased striatal DA and DOPAC contents and increased NE contents, effects reversed by ω3. This drug protected hippocampal neuron degeneration, as observed by Fluoro-Jade staining, and the increased immunostainings for TNF-alpha, COX-2, and iNOS were partly or totally blocked by ω3. Conclusion. This study showed a neuroprotective effect of ω3, in great part due to its anti-inflammatory properties, stimulating translational studies focusing on its use in clinic for stroke managing.
RESUMO
Valproic acid (VA) is a major antiepileptic drug, used for several therapeutic indications. It has a wide activity spectrum, reflecting on mechanisms of action that are not fully understood. The objectives of this work were to study the effects of VA on acute models of nociception and inflammation in rodents. VA (0.5, 1, 10, 25, and 50 mg/kg, p.o.) effects were evaluated on the carrageenan-induced paw edema, carrageenan-induced peritonitis, and plantar tests in rats, as well as by the formalin test in mice. The HE staining and immunohistochemistry assay for TNF-α in carrageenan-induced edema, from paws of untreated and VA-treated rats, were also carried out. VA decreased paw edema after carrageenan, and maximum effects were seen with doses equal to or higher than 10 mg/kg. VA also preserved the tissue architecture as assessed by the HE staining. Immunohistochemical studies revealed that VA significantly reduced TNF-α immunostaining in carrageenan-inflamed rat paws. In addition, the anti-inflammatory action of VA was potentiated by pentoxifylline (a phosphodiesterase inhibitor, known to inhibit TNF-α production), but not by sodium butyrate or by suberoylanilide hydroxamic acid (SAHA), nonspecific and specific inhibitors, respectively, of histone deacetylase. However, the decrease in the number of positive TNF-α cells in the rat paw was drastically potentiated in the VA + SAHA associated group. VA also reduced leukocytes and myeloperoxidase (MPO) releases to the peritoneal exudate, in the carrageenan-induced peritonitis. Although in the formalin test, VA inhibited both phases, the inhibition was mainly on the second phase. Furthermore, VA significantly increased the reaction time to thermal stimuli, as assessed by the plantar test. VA is a multi-target drug, presenting potent antinociceptive and anti-inflammatory properties at a lower dose range. These effects are partly dependent upon its inhibitory action on TNF-α-related pathways. However, the participation of the HDAC inhibition with the VA anti-inflammatory action cannot be ruled out. Inflammatory processes are associated with free radical damage and oxidative stress, and their blockade by VA could also explain the present results.
