Depression is a common disease affecting more than 300 million people worldwide. Since has shown central nervous system effects in previous works, we aimed to investigate the effect of essential oil and its major compound, thymol on a corticosterone-induced depression model in mice. Male mice (20⁻25 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 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 < 0.05. It was shown that 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 essential oil, thymol and fluoxetine reversed anhedonia. These results suggest that the thymol and 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.
Objetivo: Analisar a condição epidemiológica da tuberculose no município de Sobral (CE) entre os anos de 2013 e 2017. Métodos: O estudo está sob o aspecto epidemiológico quantitativo mediante o levantamento de dados de domínio público e de abrangência nacional, alimentados por meio da notificação compulsória de doenças e agravos. A pesquisa foi realizada com base nos elementos epidemiológicos da cidade de Sobral, região Norte do Ceará, com dados referentes ao período de 2013 a 2017. Resultados: Foram notificados 993 casos de tuberculose no município, sendo tais acometidos adultos jovens, entre 20 e 59 anos, somando 721 casos. Os indivíduos do sexo masculino foram mais prevalentes em relação ao sexo feminino. A grade maioria dos episódios notificados constituiu de casos novos em todos os anos estudados. Os casos de tuberculose pulmonar constituíram 84% e a maior parcela dos casos notificados (54%) era positiva para o bacilo na primeira baciloscopia. A cura constituiu maior percentual entre os encerramentos dos casos. Conclusão: Os resultados explanam a situação epidemiológica de tuberculose em Sobral (CE) e apontam para um fortalecimento nas estratégias dos serviços de saúde, principalmente relacionado ao diagnóstico precoce dos casos, com a finalidade de combater a doença no município.
