Phytol, a branched chain unsaturated alcohol, is particularly interesting because it is an isolated compound from essential oils of different medicinal plants. The aim of this study was to evaluate the anxiolytic-like effects of phytol in animal models to clarify their possible action mechanism. After acute intraperitoneal treatment with phytol at doses of(More)
The aim of this study was to evaluate the neuroprotective effects of nerolidol in mice hippocampus against oxidative stress in neuronal cells compared to ascorbic acid (positive control) as well as evaluated the nerolidol sedative effects by open field test compared to diazepam (positive control). Thirty minutes prior to behavioral observation on open field(More)
Blood fluke of the genus Schistosoma are the etiological agents of human schistosomiasis, an important neglected tropical disease that afflicts over 200 million people worldwide. The treatment for this disease relies heavily on a single drug, praziquantel. Recent reports of praziquantel resistance raise concerns about future control of the disease and show(More)
2-[(2,6-dichlorobenzylidene)amino]-5,6-dihydro-4H-cyclopenta[b]thiophene-3-carbonitrile), 5TIO1, is a new 2-aminothiophene derivative with a promising pharmacological activity. The aim of this work was to evaluate the potential anxiolytic effect of 5TIO1 in animal models. In the elevated plus-maze test, 5TIO1 (0.1, 1.0 and 10.0 mg/kg, i.p) increased the(More)
Studies showing anxiolytic-like properties of natural products have grown. This paper evaluated if carvacryl acetate (CA) could be studied as an alternative drug to treat anxiety disorders. Elevated plus maze (EPM) tests , light-dark box (LDB) tests, and marble-burying tests (MBTs) were performed on mice. In the first protocol, the anxiolytic-like(More)
The present study evaluated anxiolytic activity of (+)-limonene epoxide (EL), through the marble burying test (MBT) assay, and the antioxidant potential in vitro and in vivo in mice hippocampus of adult mice subjected to experimental anxiety protocol. For behavioral studies, and in vivo antioxidant analyses, mice were treated orally with 0.05% Tween 80(More)
Estudos comportamentais e das alterações histopatológicas em camundongos pré-tratados com Bellis perennis no modelo de convulsão induzido por pilocarpina [Behavioral studies and histopathological changes in mice pretreated with Bellis perennis in pilocarpine-induced seizures.] Abstract The aim of this study was to investigate the potential neuroprotective(More)
Blood flukes of the genus Schistosoma are the causative agents of human schistosomiasis, a debilitating disease that afflicts over 200 million people worldwide. Praziquantel is the drug of choice but concerns over praziquantel resistance have renewed interest in the search for alternative drug therapies. Carvacrol, a naturally occurring monoterpene phenol(More)
Two cases of chagasic megacolon associated with colon cancer are reported. This is the first communication with complete clinical details of this association. Our two cases presented tumors (adenocarcinomas) in a nondilated segment of the transverse colon. The associated tumor lesions were diagnosed by a barium enema. Both patients had a typical clinical(More)
2-[(2,6-Dichlorobenzylidene)amino]-5,6-dihydro-4H-cyclopenta[b]thiophene-3-carbonitrile, 5TIO1, is a new 2-aminothiophene derivative with promising pharmacological activities. The aim of this study was to evaluate its antioxidant activity in different areas of mice central nervous system. Male Swiss adult mice were intraperitoneally treated with Tween 80(More)
