anxiolytic/癲癇性発作

Most antidepressants lower seizure threshold, which might be due to the modulation of serotonergic neurotransmission. Here, we investigated the effects of two 5-HT1A, 5-HT7 and 5-HT3 antagonists, i.e., 1-(2-(2-(2,6-dimethylphenoxy)ethoxy)ethyl)-4-(2-methoxyphenyl)piperazine hydrochloride (HBK-14)

Buspirone, gepirone and ipsaperone administered intraperitoneally (40 mg/kg) to naive rats were found to be proconvulsive for strychnine-induced seizures. The dose of strychnine required to induce seizures in 50% of test animals (CD50) was 2.18 mg/kg in naive rats, while CD50s for rats treated with

1. Convulsions were induced reproducibly by intracerebroventricular injection of N-methyl-D-aspartic acid (NMDA) to conscious mice. 2. Competitive (carboxypiperazine-propylphosphonic acid, CPP; 2-amino-7-phosphonoheptanoic acid, AP7) and non-competitive (MK801; phencyclidine, PCP;

Cocaine abuse may lead to overdose (related to seizures and/or status epilepticus) and to diseases (schizophrenia, depression, and anxiety). This work was designed to study the influence of drugs used to treat psychopathologies associated with cocaine abuse on cocaine-induced seizures and mortality

In this paper we examined the effect of flumazenil (Ro 15-1788, 10 mg/kg), a benzodiazepine receptor antagonist, on the anticonflict activity of DL-(E)-2-amino-4-methyl-5-phosphono-3-pentenoic acid (CGP 37849), a competitive N-methyl-D-aspartate (NMDA) receptor antagonist, and

Allopregnanolone (AlloP), GABA(A) positive modulator, has efficacy as anticonvulsant. In contrast, nicotine and pregnenolone sulfate (PregS) act as potent convulsants. The present study aims to evaluate whether a promnesic dose of PregS and/or an anxiolytic dose of AlloP administered in the

Endogeneously occurring neuroactive steroids, metabolites of progesterone and deoxycorticosterone, have been shown previously to interact with the GABAA receptor with great specificity in vitro and to have anticonvulsant, anxiolytic and sedative activity in vivo. However, these endogenously

Crinum glaucum A. Chev (Amaryllidaceae) (CG) is a bulbous plant widely used in folk medicine in the treatment of cough, asthma and convulsions. This study was carried out to investigate the anticonvulsant, anxiolytic and hypnotic effects of the aqueous bulb extract of C. glaucum and its possible

Effects of increased levels of selective reuptake inhibitor fluoxetine were studied in Wistar male rats with different individual reactivity of the nervous system. Different behavioral models were used. In rats tolerant to audiogenic stress, drug administration led to a decrease in exploratory

The anticonvulsant BW A78U, tested in a free mouse exploratory situation, reduced in a dose-dependent fashion the locomotion and the number of rearings, this sedative effect being significant up to a dose of 15 mg/kg (IP, 20 min before testing). In an unconditioned conflict test, the light/dark box

(S)-3-methyl-5-(1-methyl-2-pyrrolidinyl)isoxazole (ABT 418), an isoxazole analog of (-)-nicotine, is a potent agonist at the alpha-4/beta-2 subtype of neuronal nicotinic acetylcholine receptor (nAChR) that exists in mammalian brain (Arneric et al., 1994). Compared to (-)-nicotine, ABT 418 has

A series of 4-phenyl-6H-imidazo[1,5-a]thieno[3,2-f][1,4]diazepine-7-carboxylate esters were synthesized and tested as central benzodiazepine receptor (CBR) ligands by the ability to displace [³H]flumazenil from rat cortical membranes. All the compounds showed high affinity with

Ipsapirone (TVX Q 7821, 2-(4-(4-(2-pyrimidinyl)-1-piperazinyl)butyl)-1,2-benzisothiazol-3- (2H)one-1, 1-dioxidehydrochloride), a new anxiolytic drug in respect of the evaluation of its effect on central 5-hydroxytryptamine (5-HT), noradrenaline and dopamine functions was studied. It was found that

Drugs used to treat anxiety have many negative side effects including addiction, depression, suicide, seizures, sexual dysfunction, headaches and more. Anxiolytic medications do not restore normal levels of neurotransmitters but instead manipulate the brain chemistry. For example, selective

Huntington's disease (HD) is a neurodegenerative condition characterised by motor dysfunction with involuntary movements and loss of voluntary control, cognitive deterioration and psychiatric problems. We report a 51-year-old man with early HD who experienced stereotyped episodes of repetitive,
