cytisine/癲癇性発作

Cytisine (CYT) is a partial agonist of brain α4β2 nicotinic acetylcholine receptors widely used in Central/Eastern Europe for smoking cessation. This study evaluated the effect of CYT on the ability of classical and novel antiepileptic drugs to prevent seizures evoked by the 6-Hz test, a model of

BACKGROUND Cytisine (CYT), the most commonly used drug for smoking cessation in Poland, was experimentally found to induce convulsions. There is a lack of studies on the influence of CYT on the anticonvulsant activity of antiepileptic drugs (AEDs). METHODS The effects of CYT on the anticonvulsant

The nature of the central receptors mediating the convulsant actions of nicotine has been investigated. Clonic tonic convulsions were seen in mice following intracerebroventricular (i.c.v.) injection of nicotinic agonists. (-)Nicotine was the most potent agonist tested, with a CD50 of 7.9 X 10(-9)

Planarians are traditional model invertebrates in regeneration and developmental biology research that also display a variety of quantifiable behaviors useful to screen for pharmacologically active compounds. One such behavior is the expression of seizure-like movements (pSLMs) induced by a variety

This study extends the pharmacological characterization of the genotype- dependent difference in analgesic responsiveness to neuronal nicotinic agonists between CD-1 and CF-1 strains of mice. Acute analgesic potency of cytisine measured by the tail-flick assay differed by > 3200-fold between CD-1

There are acetylcholine receptors throughout the central nervous system, and they may mediate some forms and aspects of convulsive activity. Most high-affinity binding sites on nicotinic acetylcholine receptors for nicotine, cytisine, and epibatidine in the brain contain the beta2 subunit of the

The studies outlined here used pharmacological and genetic approaches to attempt to identify the nicotinic receptors that modulate nicotine-induced seizures. Full-blown clonic-tonic seizures were induced by intracerebroventricular (i.c.v.) injection of nicotine, the alpha4beta2 selective agonist

BACKGROUND Studies in rodents selectively bred to differ in alcohol sensitivity have suggested that nicotine and ethanol sensitivities may cosegregate during selective breeding. This suggests that ethanol and nicotine sensitivities may in part be genetically correlated. METHODS Male and female high

An outbreak of neurological disorders in a flock of 20 sheep coming from a rural farm in Civitella Roveto, Italy, occurred in winter 2015. All the animals showed tonic-clonic convulsions followed by muscle paralysis associated with dilated pupils, tremor, tachycardia, tachypnea and diarrhea. The

ABT-089 [2-methyl-3-(2-(S)-pyrrolidinylmethoxy)pyridine dihydrochloride salt] is a selective neuronal nicotinic receptor (NNR) modulator with cognitive enhancing properties in animal models of cognitive functioning. Amongst NNR subtypes, ABT-089 shows selectivity for the cytisine binding site on the

Planarians are traditional animal models in developmental and regeneration biology. Recently, these organisms are arising as vertebrate-relevant animal models in neuropharmacology. Using an adaptation of published behavioral protocols, we have described the alleviation of cocaine-induced planarian

Green tobacco sickness occurs from transdermal absorption of chemicals from freshly harvested, green tobacco leaves. Signs and symptoms include nausea, vomiting, headache, and abdominal cramps. Prevalence has shifted from the United States and Europe to China, India, and Brazil. Worldwide 8 million

BACKGROUND Smoking is the leading preventable cause of illness and premature death worldwide. Some medications have been proven to help people to quit, with three licensed for this purpose in Europe and the USA: nicotine replacement therapy (NRT), bupropion, and varenicline. Cytisine (a treatment
