RESUMEN
Abstract Increased anxiety and depressive symptoms have reported to be its association with long term illness. Because of having unwanted effects of newly available drugs, patients administering anxiolytic drugs usually discontinue the treatment before they are completely recovered. Therefore, there is a serious need to develop new anxiolytic drugs. The anxiolytic effect of hydro-alcoholic extract of Agaricus blazei in animal models was assessed. 24 male mice (Mus musculus genus) were included in the study. Four groups were prepared and each group contained six animals. The groups were vehicle control, positive control (diazepam 1.0 mg/kg, i.p.) as well as two treatment groups receiving Agaricus blazei hydro-alcoholic extract at a dose of 136.50 mg/kg and 273.0 mg/kg orally. The Marble burying test, Nestlet shredding test and Light and Dark box test used to assess anxiolytic activity. Mice administered with diazepam 1.0 mg/kg, i.p. while hydro-alcoholic extract of AbM (136.50 and 273.0 mg/kg, respectively) was administered via oral route which exhibited marked reduction in number of marbles-burying as compared to vehicle control group. Mice administered with diazepam 1.0 mg/kg, i.p. and Oral administration of hydro-alcoholic extract of AbM (136.50 and 273.0 mg/kg, respectively) exhibited significant decrease in nestlet shredding in comparison to vehicle control group. The oral administration of hydro-alcoholic extract at a dose of 136.5mg/kg and 273mg/kg showed elevation in time spent in light box and was comparable to standard treated group while time spent by mice following oral administration of hydro-alcoholic extract of Agaricus blazei at a dose of 273.0 mg/kg also showed elevation and was found to be more near to standard treated group (diazepam 1 mg/kg, i.p.).
Resumo O aumento da ansiedade e dos sintomas depressivos têm relatado sua associação com doenças de longa duração. Por causa dos efeitos indesejáveis dos novos medicamentos disponíveis, os pacientes que administram medicamentos ansiolíticos geralmente interrompem o tratamento antes de estarem completamente recuperados. Portanto, há uma necessidade séria de desenvolver novos medicamentos ansiolíticos. Foi avaliado o efeito ansiolítico do extrato hidroalcoólico de Agaricus blazei em modelos animais. Vinte e quatro camundongos machos (gênero Mus musculus) foram incluídos no estudo. Quatro grupos foram preparados, e cada grupo continha seis animais. Os grupos foram controle de veículo, controle positivo (diazepam 1,0 mg/kg, i.p.), bem como dois grupos de tratamento recebendo extrato hidroalcoólico de Agaricus blazei na dose de 136,50 mg/kg e 273,0 mg/kg por via oral. O teste de enterrar Marble, o teste de retalhamento Nestlet e o teste de caixa clara e escura são usados para avaliar a atividade ansiolítica. Camundongos foram administrados com diazepam 1,0 mg/kg, i.p., enquanto o extrato hidroalcoólico de AbM (136,50 e 273,0 mg/kg, respectivamente) foi administrado por via oral, que exibiu redução acentuada no número de mármores enterrados em comparação com o grupo de controle de veículo. Camundongos administrados com diazepam 1,0 mg/kg, i.p. e a administração oral de extrato hidroalcoólico de AbM (136,50 e 273,0 mg/kg, respectivamente) exibiu diminuição significativa na trituração de ninhos em comparação ao grupo de controle de veículo. A administração oral de extrato hidroalcoólico na dose de 136,5mg/kg e 273mg/kg mostrou elevação no tempo gasto na caixa de luz e foi comparável ao grupo tratado padrão, enquanto o tempo gasto por camundongos após a administração oral de extrato hidroalcoólico de Agaricus blazei na dose de 273,0 mg/kg também mostrou elevação e foi mais próximo do grupo tratado padrão (diazepam 1 mg/kg, ip).
