Cannabinoids, the active ingredients of Cannabis sativa, have been used by humans as hallucinogens and therapeutic agents for thousands of years. These agents are now known to act through the cannabinoid CB1 and CB2 receptors. The recent discovery of endogenous cannabinoids and the fact that they
OBJECTIVE
Cirrhosis is associated with blunted cardiovascular response to stimuli such as hemorrhage, but the mechanism remains unclear. We aimed to clarify the role of endocannabinoids in blunted hemorrhage response in cirrhotic rats.
METHODS
Cirrhosis was induced by bile duct ligation (BDL).
Endocannabinoid anandamide, arachidonylethanolamine (AEA), is considered to be a causative mediator of hemorrhagic or septic shock, inducing death of several types of cells by producing free radicals such as reactive oxygen species (ROS). Propofol contains a phenolic hydroxyl group that donates
Anandamide, an endogenous cannabinoid ligand, binds to CB1 cannabinoid receptors in the brain and mimics the neurobehavioural actions of marijuana. Cannabinoids and anandamide also elicit hypotension mediated by peripheral CB1 receptors. Here we report that a selective CB1 receptor antagonist,
Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used analgesics, but can cause gastric and esophageal hemorrhages, erosion, and ulceration. The endogenous cannabinoid (endocannabinoid; eCB) system possesses several potential targets to reduce gastric inflammatory states, including
The role of anandamide in the development of inflammatory hyperalgesia and visceral hyperreflexia was studied in the rat urinary bladder. Animals were given intraperitoneal cyclophosphamide injection, which evokes painful hemorrhagic cystitis accompanied by increased bladder reflex activity. The
The endocannabinoid anandamide is an emerging potential signalling molecule in the cardiovascular system. Anandamide causes vasodilatation, bradycardia and hypotension in animals and has been implicated in the pathophysiology of endotoxic, haemorrhagic and cardiogenic shock, but its vascular effects
The endocannabinoid system is a component of the neuroprotective mechanisms that an organism displays after traumatic brain injury (TBI). A diurnal variation in several components of this system has been reported. This variation may influence the recovery and survival rate after TBI. We have
Elucidation of mechanisms regulating microcirculatory vascular tone is a key issue in the knowledge of human pathophysiology. Anandamide is an endogenous lipidic cannabinoid (CB) characterized by potent vasodilator activity acting mainly through the activation of CB receptors, located on the vessel
The prototypic endocannabinoid, anandamide, and synthetic analogues have been shown to elicit pressor and depressor effects, bradycardia, vasorelaxation, and inhibition of neurotransmission in the central and peripheral nervous systems. Cannabinoid-mediated inhibition of neurotransmission is
The psychoactive properties of cannabinoids, the biologically active constituents of the marijuana plant, have long been recognized. Recent research has revealed that cannabinoids elicit not only neurobehavioral, and immunological, but also profound cardiovascular effects. Similar effects can be
Marijuana is a widely abused recreational drug well known for its psychoactive properties. Cannabinoids, the active ingredients of marijuana, elicit their neurobehavioral effects by interacting with the CB1 cannabinoid receptor subtype, expressed primarily in the brain but also present in some
Acute hypotension, hypoxemia, cardiac arrhythmias, cardiac arrest, (or a combination of these), and sudden death are well-recognized complications of the cemented hip arthroplasty procedure. Collectively, these are known as the bone cement implantation syndrome (BCIS). The endogenous cannabinoids,
BACKGROUND
The endocannabinoid anandamide is implicated in the pathogenesis of hypotension in haemorrhagic, endotoxic, and cardiogenic shock. It has been demonstrated in animal, but not in human, vessels that the vasodilatory effects of anandamide and abnormal cannabidiol are partially mediated by
BIA 10-2474 (3-(1-(cyclohexyl(methyl)carbamoyl)-1H-imidazol-4-yl)pyridine 1-oxide) is a novel fatty acid amide hydrolase (FAAH) inhibitor developed by BIAL for the treatment of medical conditions which would benefit from enhanced levels of endogenous anandamide (AEA) such as pain disorders. During a
