aconitine/seizures

Aconitine effects on the hippocampal slice preparation have been well documented and include acute inhibitory and prolonged excitatory effects. To date, the effect of aconitine on neocortical activity has not been investigated. The aim of this study was to characterise the acute and long term

Altered autonomic activity has been implicated in the development of cardiac dysfunction during seizures. This study investigates whether intervening in seizure progression with diazepam will reduce seizure-induced cardiomyopathy. Second, this study examines the hypothesis that combining atenolol

Lethal cardiac arrhythmias contribute to mortality in a number of pathological conditions. Several parameters obtained from a non-invasive, easily obtained electrocardiogram (ECG) are established, well-validated prognostic indicators of cardiac risk in patients suffering from a number of

Despite much research, there remains controversy over the role of gap junctions in seizure processes. Many studies report anticonvulsant effects of gap junction blockade, but contradictory results have also been reported. The aim of this study was to clarify the role of connexin36 (Cx36) gap

BACKGROUND Cardiotoxicity in acute aconitine intoxication is well known; however, elevation of troponin I level and abnormal scintigraphy findings had not previously been reported. METHODS A 60-year-old man developed chest tightness, syncope and convulsion after ingesting processed Aconitum

CGS 19755 (cis-4-phosphonomethyl-2-piperidine carboxylic acid) was found to be a potent, stereospecific inhibitor of N-methyl-D-aspartate (NMDA)-evoked, but not KCl-evoked, [3H] acetylcholine release from slices of the rat striatum. The concentration-response curve to NMDA was shifted to the right

The new antiarrhythmic drug propafenone and its main human metabolite 5-hydroxypropafenone were investigated for antiarrhythmic, local anaesthetic, Ca++-antagonistic and beta-adrenoceptor blocking effects as well as for their activity on the central nervous system. In isolated organs (guinea-pig

The anticonvulsants phenytoin and carbamazepine interact allosterically with the batrachotoxin binding site of sodium channels. In the present study, we demonstrate an autoradiographic technique to localize the batrachotoxin binding site on sodium channels in rat brain using [3H]batrachotoxinin-A

Seizures are associated with altered autonomic activity, which has been implicated in the development of cardiac dysfunction and structural damage. This study aimed to investigate the involvement of the autonomic nervous system in seizure-induced cardiomyopathy. Male Sprague-Dawley rats (320-350 g)

Status epilepticus (SE) is a seizure or series of seizures that persist for >30 min and often results in mortality. Death rarely occurs during or immediately following seizure activity, but usually within 30 days. Although ventricular arrhythmias have been implicated in SE-related mortality, the

Verapamil, nifedipine, perhexiline and SKF 525-A (2-diethylaminoethyl-2,2-diphenylvalerate . HCL) were evaluated for cardiac antiarrhythmic activity by assessing their effectiveness in increasing left ventricular fibrillation threshold (FT) and antagonizing ouabain-induced arrhythmias (OA), 24 h

Alkaloids of Aconitum spec. (Ranunculaceae) are employed in traditional Chinese folk medicine as analgesics. The present study was designed in order to investigate the effects of the structurally related alkaloids aconitine, lappaconitine, and 6-benzoylheteratisine on experimentally induced

3-(2-Carboxypiperazin-4-yl)propyl-1-phosphonic acid (CPP) was synthesized as a rigid analog of 2-amino-7-phosphonoheptanoate, a previously known antagonist at the N-methyl-D-aspartate (NMDA) preferring, or NMDA-type, of excitatory amino acid receptor. CPP was found to be a potent, selective and

Voltage-gated Na(+) channels are heteromeric membrane glycoproteins responsible for the generation of action potentials. A number of diverse lipid-soluble neurotoxins, such as batrachotoxin, veratridine, aconitine, grayanotoxins, pyrethroid insecticides, brevetoxins and ciguatoxin, target
