background: resistance to antiepileptic drugs as well as intolerability in 20-30% of the patients raises demand for developing new drugs with improved efficacy and safety. acceptable anticonvulsant activity, good tolerability, and inexpensiveness of docosahexaenoic acid (dha), make it as a good candidate for designing and development of the new anticonvulsant medications. methods: ten dha-based...

objective: nitric oxide (no) plays an important role both as a consequence and as a cause of epileptic seizures.regarding the central nervous system depressant effects of achillea wilhelmsii (a. wilhelmsii), as well the effects of the plant on no, this study was aimed to elucidatethe possible role for nitric oxide on the effects of hydroalcoholic extract of a. wilhelmsii on pentylenetetrazole (...

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...

The topical application of strychnine, d-tubocurarine, pentylenetetrazole, picrotoxin, and physostigmine evoked different patterns of electrical activity in a portion of the acutely isolated suprasylvian gyrus of dogs. Pentylenetetrazole and picrotoxin evoked a similar pattern of activity in the isolated gyrus by both topical application and intravenous administration. Reasonable systemic doses...

The seizure sensitivities to pentylenetetrazol (Ptz, 25-100 mg/kg) and strychnine (S, 2 mg/kg) were tested in two mice lines selected for large (LB) and small (SB) brain weight (brain weight difference being approximately 75 mg). The selection was based on a regression line connecting body and brain weight. SB mice were more sensitive to both drugs-their seizure latencies were shorter and letha...

The cellular basis of kindling was studied electrophysiologically with slices of guinea pig hippocampus. Normally, epileptiform activity can be induced in the slices only by combined exposure to elevated potassium levels and a chemical convulsant such as penicillin. In hippocampal slices from pentylenetetrazole-kindled animals, however, elevated potassium alone can induce seizures. These data s...

Anticonvulsant activity of the methanolic extract of Prosopis Cineraria (Linn) Druce stem barks was studied against maximal electro shock (MES) and Pentylenetetrazole (PTZ) induced convulsions in mice. The extract suppressed hind limb tonic extensions (HLTE) induced by MES and also exhibited Protector Effect in PTZInduced Seizures. In conclusion, the methanolic extract of Prosopis Cineraria (Li...
