2. Impairment of locomotor activity induced by the novelN-acylhydrazone derivatives LASSBio-785 and LASSBio-786 in mice
The N-acylhydrazone (NAH) analogues N-methyl 2-thienylidene 3,4-benzoylhydrazine (LASSBio-785) and N-benzyl 2-thienylidene 3,4-benzoylhydrazine (LASSBio-786) were prepared from 2-thienylidene 3,4-methylenedioxybenzoylhydrazine (LASSBio-294). The ability of LASSBio-785 and LASSBio-786 to decrease central nervous system activity was investigated in male Swiss

3. Anxiolytic-like and sedative effects of Kyllinga brevifolia in mice
Kyllinga brevifolia Rottb., Cyperaceae, rhizomes have been widely used in the Paraguayan folk medicine as digestive, diuretic, sedative, tonic, antispasmodic and sudorific. The purpose of this study is to characterize the putative sedative, anxiolytic effects of the crude hydro-ethanolic extract (CEKb) and fractions of the rhizome of K. brevifolia, in male m

4. Avaliação da atividade tipo ansiolítica do óleo essencial das folhas de Spiranthera odoratissima A. St. Hil. - possível mecanismo envolvido / Anxiolytic-like activity of essential oil from Spiranthera odoratissima A. St. Hil. leaves possible mechanism evolved
Anxiety is among the most common chronic disease in the world. In Brasília city (capital of Brazil), anxiety disorders affect 12.1 % of population and are the most prevalent psychiatry disease. Since the introduction of benzodiazepines in the 1960s, they have been the most commonly prescribed treatment for anxiety disorders. However, their side-effects such

5. Effects of a hydroalcoholic extract of Turnera diffusa Willd. ex Schult., Turneraceae, in tests for adaptogenic activity
The objective of the present study was to assess whether Turnera diffusa Willd. ex Schult., Turneraceae, (TD), plant known in popular medicine as tonic and aphrodisiac, has other effects that are characteristic of an adaptogen substance, such as improvement of the memory and reduction of the damage caused by stress. We carried out an initial screening to det

6. Hypnotic effect of ecdysterone isolated from pfaffia glomerata (spreng.) pedersen / Efeito hipinótico de ecdisterona isolada de Pfaffi a glomerata (Spreng.) Pedersen
Neste trabalho foi avaliado, em roedores, o efeito depressor das frações clorofórmio (CHCl3), acetato de etila (EtOAc) e n-butanol, obtidas das partes subterrâneas de Pfaffi a glomerata, empregando-se o teste de tempo de sono barbitúrico como referência. Somente a fração lipofílica (CHCl3:EtOAc, 1:1, m/m) (i.p. 500 mg/kg; v.o. 1000 mg/kg) potenciou

7. Potentiation of carbon tetrachloride hepatotoxicity by pentosan polysulfate in rats
Few data are available in the literature regarding the effect of pentosan polysulfate (PPS) on normal and fibrotic rat livers. In addition, the combination of PPS and carbon tetrachloride (CCl4) has not been studied so far. The objective of this study was to assess the effect of PPS on rat livers treated or not with CCl4 for the induction of liver fibrosis.

8. InvestigaÃÃo dos efeitos centrais e gastroprotetores do isopulegol em camundongos / Evaluation of the central nervous system and gastroprotective effects of isopulegol in mice.
Isopulegol is a monoterpene alcohol present in the essential oils of various plants, and has been used in the manufacture of fragrances with blossom compositions. In order to investigate its effects on animal models of CNS actions, isopulegol was administered to male Swiss mice at single doses of 25 and 50 mg/kg 30 (i.p.) or 60 min (p.o.) before the experime

9. Pharmacologycal and auto-radiographical study of GABAA/benzodiazepine site, and biochemical assays of the Na+/K+-ATPase and of the glutamatergic receptors in rats susceptible and non-susceptible to clonic convulsions induced by DMCM, a benzodiazepine inverse agonist. / Estudo farmacológico e auto-radiográfico do complexo GABAA/Sítio benzodiazepínico, e ensaios bioquímicos da enzima Na+/K+- Atpase e de receptores glutamatérgicos em regiões encefálicas de ratos susceptíveis e não-susceptíveis às convulsões clônicas induzidas pelo DMCM, um agonista inverso benzodiazepínico.
Objective: The aim of this work was to verify if rats susceptible and non-susceptible to clonic convulsions induced by DMCM, a benzodiazepine inverse agonist, differ: 1) in the sensitivity to the hypnotic effect induced by diazepam and by others positive allosteric modulators of GABAA receptors; 2) in auto-radiographical analysis of [3H]-flunitrazepam bindin

10. Antinociceptive properties in mice of a lectin isolated from the marine alga Amansia multifida Lamouroux
The antinociceptive effects of a lectin (LEC) isolated from the marine alga Amansia multifida were determined in Swiss mice. The LEC (1, 5, and 10 mg/kg) inhibited acetic acid-induced abdominal writhings in a dose-dependent manner after intraperitoneal or oral administration. A partial but significant inhibition of writhings was observed after the combinatio
