tetrahydrocannabinol/infarction

Delta(9)-tetrahydrocannabinol (Delta(9)-THC), a primary psychoactive constituent of cannabis, has been reported to act as a neuroprotectant via the cannabinoid CB(1) receptor. In this study, Delta(9)-THC significantly decreased the infarct volume in a 4 h mouse middle cerebral artery occlusion mouse

OBJECTIVE To demonstrate the clinical characteristics, radiologic findings, and neuropathological features of tetrahydrocannabinol-related posterior fossa ischemic stroke in adolescent patients. METHODS A retrospective case and chart review of 3 cases encountered at a tertiary care institution over

Many reports of marijuana-associated myocardial infarct (MI) are limited by incomplete evaluation of the toxicologic exposure, a lack of definitive anatomic findings, and the potential for comorbid coronary atherosclerosis inherent in an adult population. We report a 16-year-old adolescent boy who

Tetrahydrocannabinol (THC), the major psychoactive component of marijuana, is a cannabinoid agonist that exerts its effects by activating at least two specific receptors (CB1 and CB2) that belong to the seven transmembrane G-protein coupled receptor (GPCR) family. Both CB1 and CB2 mRNA and proteins

BACKGROUND Synthetic cannabinoids (SC) are recreational designer drugs intended to mimic delta-9-tetrahydrocannabinol while surreptitiously circumventing classification by the Drug Enforcement Administration. METHODS A 50-year-old black male arrived in the Emergency Department transported by

Delta-9-tetrahydrocannabinol (THC) is increasingly used for the long-term treatment of nausea, vomiting, cachexia, and chronic pain. Recent reports, however, have indicated an increased risk of myocardial infarction and thromboangiitis obliterans after THC intake. Blood platelets have an essential

Cannabidiol, a non-psychoactive constituent of cannabis, has been reported as a neuroprotectant. Cannabidiol and Delta(9)-tetrahydrocannabinol, the primary psychoactive constituent of cannabis, significantly decreased the infarct volume at 4 h in the mouse middle cerebral artery occlusion model. The

Cannabinoids can mimic the infarct-reducing effect of early ischemic preconditioning, delayed ischemic preconditioning, and ischemic postconditioning against myocardial ischemia/reperfusion. They do this primarily through both CB1 and CB2 receptors. Cannabinoids are also involved in remote

The use of synthetic cannabinoids is being increasingly recognised worldwide, but the chemical compositions and physiological effects of these drugs are poorly characterised and are continually changing. New substances are constantly being added to the content of synthetic cannabinoids and they are

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 pharmacological (and recreational) effects of cannabis have been known for centuries. However, it is only recently that one has identified two subtypes of G-protein-coupled receptors, namely CB1 and CB2-receptors, which mediate the numerous effects of delta9-tetrahydrocannabinol and other

A 37-year-old, one-pack-per-day tobacco smoker collapsed and died at home. At autopsy, he had an occluded left anterior descending coronary artery. Δ(9)-Tetrahydrocannabinol-carboxylic acid was found in his urine but no cannabinoids were detected in his blood. Misadventure was the inquest verdict on

We encountered evidence of myocardial infarction due to coronary thrombosis in an autopsy of an occasional marijuana smoker. These findings prompted us to perform a narrative review of the literature to determine when post-mortem toxicological tests may support a temporal relationship between

Marijuana is the most commonly abused recreational substance. With the increasing legalization of marijuana, its use is expected to rise. Delta-9-tetrahydrocannabinol (THC) is the psychotropic component of marijuana, acting via CB1 and CB2 G-protein coupled cannabinoid receptors. Marijuana has
