Ferula gummosa Boiss. (Apiaceae) which has been used as an antiepileptic remedy in Iranian traditional medicine was evaluated for anticonvulsant activity against experimental seizures. The seed acetone extract of F. gummosa protected mice against tonic convulsions induced by maximal electroshock
BACKGROUND
The mechanism of action of the ketogenic diet, a therapy for refractory epilepsy, is unknown. Our hypothesis is that acetone, one of three ketones elevated by the ketogenic diet, is directly responsible for the diet's anticonvulsant effects. This study examined the basic concepts of this
High fat and low carbohydrate diet, designated ketogenic diet, has been successfully used for the treatment of intractable epilepsy in a portion of patients, particularly in children. Several hypotheses have been worked out for the explanation of its beneficial effects, among others acetone has been
The MDR1 gene product, P-glycoprotein (P-gp), was shown to confer multidrug resistance to cancer cells, but its overexpression is also suggested to be involved in pharmacoresistance of epilepsy by acting as an energy-dependent drug-efflux pump in the blood-brain barrier (BBB). In normal brain
The purpose of these studies was to investigate the nature and mechanism of a toxicologic interaction between acetonitrile and acetone. Results of oral dose-response studies utilizing a 1:1 (w/w) mixture of acetonitrile and acetone, or varying doses of acetonitrile administered together with a
Solvent blood concentrations and subnarcotic effects (inhibition of electrically evoked seizures) were measured in rats exposed to constant or fluctuating air concentrations of toluene or acetone. A 4 hour exposure of resting rats to toluene at an air concentration of 1 and 2 mg/l, or to acetone at
OBJECTIVE
Delphinium nordhagenii belongs to family Ranunculaceae, it is widely found in tropical areas of Pakistan. Other species of Delphinium are reported as anticonvulsant and are traditionally used in the treatment of epilepsy. Delphinium nordhagenii is used by local healer in Pakistan but never
BACKGROUND
Acetone, one of the principal ketone bodies elevated during treatment with the ketogenic diet, exhibits anticonvulsant properties that may contribute to the seizure protection conferred by the diet. The anticonvulsant mechanism of acetone is unknown, but it is metabolized to several
The anticonvulsant effects of acetone have been reported in various animal models of epilepsy. We recently demonstrated that other ketone bodies, methyl ethyl ketone (MEK) and diethyl ketone (DEK), suppressed status epilepticus that was induced by lithium-pilocarpine in rat. In the present study,
OBJECTIVE
Acetone is the principal ketone body elevated in the ketogenic diet (KD), with demonstrated robust anticonvulsant properties across a variety of seizure tests and models of epilepsy. Because the majority of patients continue to receive antiepileptic drugs (AEDs) during KD treatment,
OBJECTIVE
To investigate whether ketone bodies are directly anticonvulsant.
METHODS
We tested the effects of acetoacetate (ACA), acetone, and both stereoisomers, D-(-)- and L-(+), of beta-hydroxybutyrate (BHB) on sensory-evoked seizures in Frings audiogenic seizure-susceptible mice.
RESULTS
We found
Recent interest in the anticonvulsant effects of acetone has stemmed from studies related to the ketogenic diet (KD). The KD, a high-fat diet used to treat drug-resistant seizures, raises blood and brain levels of three ketones: beta-hydroxybutyrate, acetoacetate, and acetone. An obvious question is
Male rats and female mice were exposed to vapours of toluene, o-xylene and acetone in basic or double concentrations or to binary combinations of basic concentrations, for 4 and 2 hours, respectively. Basic air concentrations were for rats and mice (in ppm): toluene 270 and 380, o-xylene 230 and
The direct injection of semicarbazide (SC), an antivitamin B6 (anti-B6), into the lateral ventricle of the mouse brain induced convulsion and tremors at a smaller dose after a shorter latent period than that in systemic administration. The symptoms were prevented by pyridoxine, aminooxyacetic acid
