Experimental results indicate a mutual interaction between cannabinoidergic and GABAergic systems; however, the interaction between these systems on corticosterone release has not been fully investigated. In this study, we treated male mice with either cannabinoid compounds alone or in combination
The time courses of the effects of acute doses of amphetamine (5 and 10 mg/70 kg), alcohol (0.3 and 0.6 g/kg), diazepam (5 and 10 mg/70 kg), and marijuana (2.0% and 3.5% delta 9-THC) on performance engendered by each of four computerized behavioral tasks were evaluated in six human subjects. These
Our aim was to evaluate the effects of marijuana (Mar) and diazepam (Dz) on lipid peroxidation (TBARS), Na + , K + ATP ase activity, levels of glutathione (GSH) and 5-hydroxytryptophan (5-HTP). Male Wistar rats were given a single dose per group: extract of Mar (100 microL/kg), Dz (5 mg/kg), Mar
Several studies have shown that cannabinoids have anticonvulsant properties that are mediated through activation of the cannabinoid CB1 receptors. In addition, endogenous cannabinoid compounds (endocannabinoids) regulate synaptic transmission and dampen seizure activity via activation of the same
Previous studies have suggested that cannabinoidergic system is involved in anxiety. However, a complete picture of cannabinoid association in the anxiety is still lacking. In the present study, we investigated the possible interaction between cannabinoidergic and GABAergic systems in the
Earlier studies have shown that combination of antibodies to S100 protein and to cannabinoid receptor type 1 in released-active form (Brizantin) may possess anxiolytic properties and decrease nicotine dependence. Released-active form of antibodies is a novel approach that permits to modify natural
Convulsant effects of abused synthetic cannabinoid (SCB) drugs have been reported in humans and laboratory animals, but the mechanism of these effects is not known. We compared convulsant effects of partial CB1R agonist ∆9-tetrahydrocannabinol (THC), full CB1R agonist SCBs JWH-018 and 5F-AB-PINACA,
The effects of the novel high affinity cannabinoid receptor agonist (+)-WIN 55,212-2 ((R)-4,5-dihydro-2-methyl-4(4-morphoinylmethyl)-1-(1-naphthalen ylcarbonyl)-6H-pyrrolo[3,2,1-ij]quinolin-6-one) on severity of dystonia were investigated in mutant Syrian hamsters with primary generalized dystonia.
BACKGROUND
The elevated risk of triggering a myocardial infarction by smoking cannabis is limited to the first 2 h after smoking.
OBJECTIVE
To examine the possible role of cannabis in cardiac deaths. CASES AND RESULTS: From 3,193 coroners' cases over 2 years, there were 13 cases where the clinical
The present work, involving clinical, behavioral, and biochemical studies, was undertaken to elucidate the probable mechanism of the observed antianxiety effects of cannabis. The population for the clinical study consisted of 50 male chronic cannabis users who were otherwise healthy and 50 matched
A case is presented involving a young woman on several illicit drugs (heroin, cocaine and cannabis) as well as two medications and a solvent used for their anesthetic and narcotic properties: thiopental, ketamine and chloroform. This complex drug use was supported by hair analysis over a 10.5 cm
It is known that an individual's drug use history affects the quality of subjective effects experienced following administration of several clinically used psychoactive drugs such as barbiturates, diazepam, and morphine. However, it is not known whether drug use history also affects responses to
BACKGROUND
There is evidence from around Europe of the availability and use of 6-(2-aminopropyl)benzofuran (6-APB) as a recreational drug. However, there is currently limited information on the acute toxicity of this compound. We describe here a case of acute toxicity associated with recreational
BACKGROUND
Anxiety is among the most common and treatable mental disorders. Adrenergic and cannabinoid systems have an important role in the neurobiology of anxiety. The elevated plus-maze (EPM) has broadly been used to investigate anxiolytic and anxiogenic compounds. The present study investigated
OBJECTIVE
Activation of CB1 receptors, produces anticonvulsant effect accompanied by memory disturbance both in animal seizure tests and in patients with epilepsy. Few reports considered the role of CB2 receptor on seizure susceptibility and cognitive functions. The aim of the present study was to
