Title

Differential effects of the antidepressants tranylcypromine and fluoxetine on limbic cannabinoid receptor binding and endocannabinoid contents

Overall design

The aim of this study was to examine whether the endocannabinoid system is altered by chronic antidepressant treatment. Rats were divided into the following 3 groups: (1) control group (0.9% saline), (2) tranylcypromine group (tranylcypromine treatment at the dose of 10 mg/kg), and (3) fluoxetine group (fluoxetine treatment at the dose of 5 mg/kg. Drugs were daily intraperitoneal injecteds for 21 days. For analysis of endocannabinoid content, brain regions were subjected to a lipid extraction process. The content of the two primary endocannabinoids, anandamide and 2-arachidonylglycerol, within lipid extracts was determined using isotope-dilution liquid chromatography mass spectrometry.
