Valerenic acid (VA)-a β2/3-selective GABA type A (GABAA) receptor modulator-displays anxiolytic and anticonvulsive effects in mice devoid of sedation, making VA an interesting drug candidate. Here we analyzed β-subunit-dependent enhancement of GABA-induced chloride currents (IGABA) by a library of VA derivatives and studied their effects on pentylenetetrazole (PTZ)-induced seizure threshold and...
Flavonoids are a class of polyphenolic compounds present in fruits and vegetables. Several studies have demonstrated a relationship between the consumption of flavonoid-rich diets and the prevention of human diseases including neurodegenerative disorders. Thus, we assessed the effect of quercetin (3,3',4',5,7-pentahydroxyflavone) on oxidative stress and memory retrieval using a step-through pas...
This study aimed to examine whether celecoxib influences clonic seizure thresholds through modulation of nitric oxidergic (NO) pathway. The effect of celecoxib (1-5 mg per kg, p.o.) was investigated on clonic seizures induced by pentylenetetrazole (PTZ, 50 and 80 mg per kg, i.p.) in male Swiss mice. The interaction of celecoxib-induced effects with NO pathway was examined using a NO synthase (N...
The peptide angiotensin IV (Ang IV) influences seizure susceptibility in rat and mouse models. Indeed, Ang IV has been shown to protect rats from limbic seizures in the focal pilocarpine model. Moreover, both anticonvulsive and antiepileptogenic effects of Ang IV have been reported in the acute pentylenetetrazol (PTZ) and kindling model of generalized seizures in mice. It has been hypothesized ...
objective: regarding the anticonvulsant effects of satureja hortensis (s. hortensis) in avicenna’s book: canon of medicine; the present study was undertaken to evaluate the anti- eplileptic effects of s. hortensis aqueous and ethanolic aerial part extracts. furthermore, the mechanisms of their anticonvulsant activities were also evaluated. materials and methods: seizure was induced by pentylent...
Creatine exerts beneficial effects on a variety of pathologies in which energy metabolism and oxidative stress play an etiological role. Creatine supplements have shown beneficial effects on neurological disorders including Parkinson׳s disease, Huntington›s disease, amyotrophic lateral sclerosis, as well as Alzheimer›s disease and stroke. However, the potential benefits of creatine for patients...
Sildenafil is the first marketed phosphodiesterase 5 inhibitor for the treatment of erectile dysfunction and recently, for pulmonary hypertension. While the treatment was found to be highly effective, several adverse effects are associated with this compound. Among numerous central nervous system-related untoward effects, proconvulsant activity was reported. The purpose of this study was to ass...
Epilepsy is a neurological disorder characterized by unprovoked, recurring seizures that disrupts the nervous system and can cause mental and physical dysfunction. Based on the ethno pharmacological information of the plant, the methanolic and aqueous extracts of the flowers of Nepeta bractaeta was evaluated for its antiepileptic activity. The methanolic and aqueous extracts of the flowers of N...
Nitric oxide (NO) is known to be a neuromodulator with dual proconvulsive and anticonvul- sive action. Valeriana officinalis (VAL) was previously believed antiepileptic, but today as sedative sleep regulator. Seizures may associated abnormal electrocardio- graphic changes cardiac dysfunction arising from epilepsy related neuronal nitric (nNO). This study aimed investigate the effects of synthas...
It is believed that a deficiency of androgens, including free testosterone, may promote the development of convulsions. The present study revealed differences in the action of androsterone (AND), a major excreted metabolite of testosterone and a neurosteroid, in three commonly used seizure models in mice. AND administered intraperitoneally exhibited dose-dependent protection against tonic-cloni...
