The anticonvulsant activity (ED50) of three synthetic eugenol derivatives - phenyleugenol (PE), benzyleugenol (BE), phenylethyleugenol (PEE) - was compared to that of common antiepileptics - diphenyl-hydantoin (DPH), phenobarbital (PB), diazepam (DZ) - and the naturally occurring methyleugenol (ME)
The hippocampus is an important brain area where abnormal morphological characteristics are often observed in patients with temporal lobe epilepsy (TLE), typically showing the loss of the principal neurons in the CA1 and CA3 areas of the hippocampus. TLE is frequently associated with widening of the
OBJECTIVE
Epilepsy establishment gives rise to biochemical and morphological changes in the hippocampus. Oxidative stress, morphological changes, and mossy fiber sprouting (MFS) in the hippocampus underpin the epilepsy establishment. Eugenol is the main component of the essential oil extracted from
Granule cell dispersion (GCD), a structural abnormality, is characteristic of temporal lobe epilepsy (TLE). Eugenol (EUG) is an essential component of medicinal herbs and is suggested to exert anticonvulsant activity. However, it is unclear whether EUG ameliorates the abnormal morphological changes
BACKGROUND
Eugenol (EUG, 4-allyl-2-methoxyphenol), the main component of essential oil extracted from cloves, has various uses in medicine because of its potential to modulate neuronal excitability. However, its effects on the ionic mechanisms remains incompletely understood.
OBJECTIVE
We aimed to
The leaf essential oil of Laurus nobilis Linn., Lauraceae, which has been used as an antiepileptic remedy in Iranian traditional medicine, was evaluated for anticonvulsant activity against experimental seizures. The essential oil protected mice against tonic convulsions induced by maximal
Eugenol, which is contained in several plants including clove, has been widely used as an analgesic and anti-inflammatory drug in the dental clinic. Eugenol also has anesthetic effects and produces sedation and the reduction of convulsion threshold. These benefits have been partly attributed to the
Many essential oils (EOs) have anticonvulsant activity and might benefit people with epilepsy. Lemongrass, lavender, clove, dill, and other EOs containing constituents such as asarone, carvone, citral, eugenol, or linalool are good candidates for evaluation as antiepileptic drugs. On the other hand,
Mosquito-borne diseases represent a deadly threat for millions of people worldwide. Eco-friendly mosquitocides are a priority. In Ayurvedic medicine, Plectranthus species have been used to treat heart disease, convulsions, spasmodic pain and painful urination. In this research, we evaluated the
How sodium metabisulfite (SMB; Na2S2O5), a popular food preservative and antioxidant, interacts with excitable membrane and induces excitotoxicity is incompletely understood. In this study, the patch-clamp technique was used to investigate and record the electrophysiological effect of SMB on
An essential oil fraction obtained from powdered seeds of Licaria puchury-major contained 51.3% of safrol, 3.3% of eugenol and 2.9% of methyleugenol, among other substances. Fifty to 800 mg/kg of this fraction reduced motor activity and anesthetized mice; it also protected the animals against
Species of genus Ocimum (Lamiaceae) are economically important due to their essential oils and utilization as medicine for many disorders, including the central nervous system. A previous study showed seasonal variations in chemical profile and in central nervous system activities of essential oil
Epilepsy is a most disabling neurological disorder affecting all age groups. Among the various mechanisms that may result in epilepsy, neuronal hyperexcitability and oxidative injury produced by an excessive formation of free radicals may play a role in the development of this pathology. Therefore,
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,
The high-performance counter-current chromatography was used for the efficient purification of single constituents from Thymus vulgaris essential oil. Mixtures of n-heptane, ethyl acetate, methanol, and water (5:2:5:2 and 4:1:4:1 v/v), allowed purification of eugenol, 1-octen-3- ol, borneol, thymol,
