Retigabine is a novel antiepileptic drug that influences M-type potassium currents. It is active in broad range of animal seizure models. PURPOSE. The aim of the present study is to determine the median effective dose (ED50) of Retigabine in two seizure models – maximal electroshock (MES) test and maximal pentylenetetrazole (MPTZ) test in rats. METHODS. Male Wistar rats (10 groups of 6 rats) we...

Anxiety related disorders are the most common mental illnesses and major cause of disability in man. Anxiolytic activity of methanol extract of leaves of A. brasiliana (L.) Kuntze (MEAB) was evaluated using hole board (HB), open field (OF), elevated plus maze (EPM) and light/dark exploration test (LDE) in mice. Its locomotor activity was studied using actophotometer and anticonvulsant effect wa...

DESPITE the high incidence of convulsive disorders and widespread use of shock therapy in the major psychoses, relatively few investigations have dealt with the physiological properties of experimental seizures (1, 2, 3, 10, 12, 14, 16, 17). Convulsive threshold has received considerable attention, particularly in the testing of anticonvulsant drugs (11, 13, 15, 18, 21, and others), but thresho...

For centuries, extracts of Acorus gramineus have been used extensively in traditional Chinese medicine for the treatment, management, and/or control of human ailments, including central nervous system disorders such as convulsions and epilepsy. In the present study, we investigated the anticonvulsant activity of chronic treatment with the plant's major essential oil component (a-asarone, 50-200...

Triazolo-thiadiazines 4a–f and triazolo-tetrazines 8g–l were prepared from reaction of 3-(4-amino-5-mercapto-4H-1,2,4-triazol-3-yl)-2H-chromen-2-one with the respective hydrazonoyl halides 2a–f 2g–l. Moreover, aminomercaptotriazole derivative phenacyl bromide ethyl 2-chloro-3-oxobutanoate followed by coupling products benzenediazonium chloride yielded corresponding 4f 8g, respectively. All newl...

Ocimum gratissimum L. (Lamiaceae) and other species of the same genus are used as medicines to treat central nervous system (CNS) diseases, commonly encountered in warm regions of the world. The chemical composition of Ocimum gratissimum essential oil varies according to their chemotypes: timol, eugenol or geraniol. In this study, the essential oil type eugenol was extracted by hydrodistillatio...

The objective of the present study was to evaluate the anxiolytic and anticonvulsant activity of the methanolic extract of Allium Cepa Linn (MEAC). After preliminary phytochemical evaluation, acute oral toxicity test, anxiolytic activity of methanolic extract of Allium Cepa bulbs at doses of 200 and 400 mg/kg was assessed using elevated-plus-maze (EPM), open field test (OFT), light & dark trans...

Plasma cortisol and glucose levels were measured in 36 adult Nile tilapia males, Oreochromis niloticus (standard length, mean +/- SD, 14.38 +/- 1.31 cm), subjected to electroshock and social stressors. Pre-stressor levels were determined 5 days after the adjustment of the fish to the experimental aquaria (1 fish/aquarium). Five days later, the effects of stressors on both cortisol and glucose l...

Salvia verticillata is one of the salvia species which possesses remarkable antioxidant activity. In the present study, we investigated the possible effects of hydro-alcoholic extract from Salvia verticillata plant (SVE) in various models of anxiety, depression and seizure in mice. Mice were randomly divided into control (saline), SVE-treated and standard treatment groups. The SVE-treated group...
