P 17: Electrophysiological Effects of Cannabinoid Receptor Antagonist AM251 on Harmaline Toxicity in Rat’s Cerebellar Vermis Slices
Introduction: The Cannabinoid receptors (CBR) densities are high within the cerebellum. Cannabinoid receptors manipulations have been reported to cause altering the cerebellar functions. harmaline have immune-modulatory effects in several studies. i.e., significant anti-inflammatory effect via the inhibition of prostaglandin E2 (PGE2) and tumor necrosis factor alpha (TNF-α). Endocannabino...
متن کاملThe cannabinoid 1 receptor antagonist, AM251, prolongs the survival of rats with severe acute pancreatitis.
It has recently been recognized that anandamide (arachidonylethanolamide), which is an endogeneous-cannabinoid (endocannabinoid), mediates septic shock. Cannabinoid means a mind-active material in cannabis (marijuana). Anandamide is mainly produced by macrophages. Cannabinoid 1 (CB1) receptor, which is one of the cannabiniod receptors, is also known to mediate hypotensive shock. The role of end...
متن کاملInteraction between Antagonist of Cannabinoid Receptor and Antagonist of Adrenergic Receptor on Anxiety in Male Rat
Introduction: 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 the effects of intraperitoneal (IP) injection of cannabinoid CB1 receptor antagonist (AM251) i...
متن کاملCannabinoid CB1 receptor as a target for chlorpyrifos oxon and other organophosphorus pesticides.
Binding of the endocannabinoid anandamide or of Delta(9)-tetrahydrocannabinol to the agonist site of the cannabinoid receptor (CB1) is commonly assayed with [3H]CP 55,940. Potent long-chain alkylfluorophosphonate inhibitors of agonist binding suggest an additional, important and closely-coupled nucleophilic site, possibly undergoing phosphorylation. We find that the CB1 receptor is also sensiti...
متن کاملPurification of two rat hepatic proteins with A-esterase activity toward chlorpyrifos-oxon and paraoxon.
A-esterases are calcium-dependent hydrolases that can detoxify the active metabolites (oxons) of organophosphorus insecticides such as chlorpyrifos and parathion. A-esterases from rat liver have previously been shown to hydrolyze chlorpyrifos-oxon but not paraoxon at low substrate concentrations. Two A-esterases were extracted by ammonium sulfate fractionation from solubilized rat liver microso...
