OBJECTIVE
To determine the delta-9-tetrahydrocannabinol (THC) content of cannabis seizures in Egypt.
METHODS
Unheated and heated extracts of cannabis seizures were prepared from the dried flowering tops and leaves (marijuana) or from the resin (hashish) and subjected to analysis using high
Delta 9-Tetrahydrocannabinol (THC), the major psychoactive ingredient of marijuana, causes nonfatal convulsions in rabbits of a closed colony of New Zealand White rabbits (Uaz: NZW). The convulsive phenotype appears to be associated with homozygous expression of a single autosomal recessive gene
Introduction: Accidental cannabis poisoning after oral ingestion in infants is an emerging cause of intoxication with well-known clinical aspects but few data exist regarding the levels of cannabinoids in plasma and urine. Here, we present data on the concentrations of
An autosomal recessive condition (thc/thc) in our closed colony of New Zealand White rabbits (Uaz:NZW-thc) results in nonfatal, behavioral convulsions following intravenous (i.v.) injections of delta-9-tetrahydrocannabinol (THC) and other psychoactive cannabinoids of marijuana. The ontogeny of the
The influences of delta 9-tetrahydrocannabinol (THC) and cannabidiol on electrically evoked cortical potentials of conscious rats with chronically implanted electrodes were investigated. Specifically, the cannabinoids' effects on a transcallosal evoked response were compared with those of
Drug seizures containing carfentanil continue to increase in Palm Beach County, FL, USA despite international efforts to control the distribution of the drug. The analysis of drug seizures from the county in 2016 and 2017 demonstrated that carfentanil was the most commonly identified fentanyl analog
Doses of delta 9-tetrahydrocannabinol (delta 9-THC) and cannabidiol (CBD) affording the same degree of protection against seizures induced by maximal electroshock were compared for their effects on sodium-dependent high affinity choline uptake into six rat brain regions: cortex, striatum,
Rats rendered chronically epileptic by bilateral implantation of cobalt into frontal cortices were simultaneously prepared with permanent electrodes for longitudinal recording of the electroencephalogram (EEG) and electromyogram (EMG). Delta-8-tetrahydrocannabinol (delta-8-THC; 10 mg/kg),
delta 9-Tetrahydrocannabinol (delta 9-THC) was studied for potential carcinogenicity in rodents because it is the principal psychoactive ingredient in marihuana and it has potential medicinal uses. delta 9-THC in corn oil was administered by gavage to groups of male and female Fischer rats and
The mechanisms of the anticonvulsant activity of cannabidiol (CBD) and the central excitation of delta 9-tetrahydrocannabinol (delta 9-THC) were investigated electrophysiologically with conscious, unrestrained cobalt epileptic rats. The well-known antiepileptics, trimethadione (TMO), ethosuximide
A single exposure to delta-9-tetrahydrocannabinol (THC) resulted in a "rebound" hyperexcitability in the CNS in mice, which was assessed in terms of the susceptibility of the CNS to electrically-induced convulsions. The magnitude of the hyperexcitability was dose-related (25-150 mg/kg, i.p.), as
Mice were kindled to produce minimal convulsions by repeated application of either electrical or chemical stimuli. Electrical kindling involved the use of corneal electrodes; chemical kindling involved the use of pentylenetetrazol or picrotoxin. Delta-9-tetrahydrocannabinol (delta-9-THC) appeared to
The effects of delta 9-tetrahydrocannabinol (delta 9-THC), two of its metabolites, 8 beta-hydroxy-delta 9-THC and 11-hydroxy-delta 9-THC, and cannabidiol were comparatively studied by means of an iron-induced cortical focal epilepsy in conscious rats with chronically implanted electrodes. delta
Experiments were performed with mice to determine whether doses of the benzodiazepine, flurazepam, or the GABA uptake inhibitor, NO-328, known to potentiate catalepsy induced by delta-9-tetrahydrocannabinol (THC), would also interact synergistically with THC in the production of certain other
