Abstract

V originále

OBJECTIVES: The self-medication hypothesis assumes that symptoms related to potential monoaminergic deficits in depression may be relieved by drug abuse. The aim of this study was to elucidate the neurotransmitter changes in a rat model of depression by measuring their levels in the nucleus accumbens shell, which is typically involved in the drug of abuse acquisition mechanism. METHODS: Depression was modelled by the olfactory bulbectomy (OBX) in Wistar male rats. In vivo microdialysis was performed, starting from the baseline and following after a single methamphetamine injection and behaviour was monitored. The determination of neurotransmitters and their metabolites was performed by high-performance liquid chromatography combined with mass spectrometry. RESULTS: OBX animals had lower basal levels of dopamine and serotonin and their metabolites. However, GABA and glutamate levels were increased. The methamphetamine injection induced stronger dopamine and serotonin release in the OBX rats and lower release of glutamate in comparison with sham-operated rats; GABA levels did not differ significantly. CONCLUSIONS: This study provides an evidence of mesolimbic neurotransmitter changes in the rat model of depression which may elucidate mechanisms underlying intravenous self-administration studies in which OBX rats were demonstrated to have higher drug intake in comparison to intact controls.

In Czech

Ve studii byly sledovány změny hladin dopaminu a jeho metabolitů v nucleus accumbens shell metodou in vivo mikrodialýzy u OBX a slepě operovaných zvířat po akutní dávce metamfetaminu. U OBX zvířat bylo zaznamenáno snížení bazálních hladin dopaminu a jeho metabolitů. Dávka metamfetaminu (5 mg/kg) však vyvolala u OBX ve srovnání s kontrolou vyšší vyplavení dopaminu a zvýšení koncentrace jeho metabolitů. Získaná data potvrzují odlišnou reaktivitu zvířat s depresi podobným fenotypem na psychostimulancia.
