Effects of partial locus coeruleus denervation and chronic mild stress on behaviour and monoamine neurochemistry in the rat
Autor: Riina Häidkind, Marika Eller, Jaanus Harro, Lars Oreland, Ago Rinken, Maarike Harro, Ants Kask
Publikováno v: European Neuropsychopharmacology. 13:19-28
It has been proposed that lesions of the ascending noradrenergic projections render animals more vulnerable to stress. In this study, the effects of partial denervation of the locus coeruleus (LC) by DSP-4 (10 mg/kg) treatment, chronic mild stress (C

Melanocortin (MC) peptides are suggested to play a role in opiate dependence, where they antagonise the addictive properties of opiates. To further study the involvement of the MCs in drug dependence, we analysed the effects of the MC(4)-receptor ant

Novel and sensitive high-performance liquid chromatographic method based on electrochemical coulometric array detection for simultaneous determination of catecholamines, kynurenine and indole derivatives of tryptophan
Autor: Uno Mäeorg, Ants Kask, Annika Vaarmann
Publikováno v: Journal of Chromatography B. 769:145-153
A novel and simple method has been developed for the simultaneous quantification of tryptophan, kynurenine and indole derivatives as well as four catecholamines, including dopamine, noradrenaline, homovanillic acid and 3,4-dihydroxyphenylacetic acid.

Factors influencing behavior of group-housed male rats in the social interaction test
Autor: Ants Kask, Reinhard Pabst, Huu Phuc Nguyen, Stephan von Hörsten
Publikováno v: Physiology & Behavior. 74:277-282
The rat social interaction (SI) test is used widely to measure anxiety-like behavior, yet the influence of various factors such as testing time, pre-experimental manipulations (transport stress), and testing of animals from the same cage (cohort remo

Chronic variable stress and partial 5-HT denervation by parachloroamphetamine treatment in the rat: effects on behavior and monoamine neurochemistry
Autor: Jaanus Harro, Ants Kask, Marika Eller, Margus Tõnissaar, Lars Oreland
Publikováno v: Brain Research. 899:227-239
Chronic variable stress (CVS) and manipulations of 5-HT-ergic neurotransmission are increasingly used as animal models of depression. In the present study, CVS for 2 weeks and a partial lesion of 5-HT projections by a small dose of parachloroamphetam

Differential Effects of Beta-Carbolines and Antidepressants on Rat Exploratory Activity in the Elevated Zero-Maze
Autor: Lembit Rägo, Ants Kask, Rein Pähkla
Publikováno v: Pharmacology Biochemistry and Behavior. 65:737-742
Present experiments were designed to compare the effects of antidepressants desipramine (10 and 20 mg/kg IP) and fluoxetine (5 and 10 mg/kg IP) with anxiogenic beta-carboline DMCM (0.5 and 1.0 mg/kg IP) in the elevated zero-maze test in rats. The sec

Orexigenic effect of the melanocortin MC4 receptor antagonist HS014 is inhibited only partially by neuropeptide Y Y1 receptor selective antagonists
Autor: Lembit Rägo, Helgi B. Schiöth, Jarl E. S. Wikberg, Ants Kask, Jaanus Harro
Publikováno v: Canadian Journal of Physiology and Pharmacology. 78:143-149
Neuropeptide Y (NPY) and melanocortin (MC) peptides have opposite effects on food intake: NPY-like peptides and MC receptor antagonists stimulate feeding and increase body weight, whereas melanocortins and NPY antagonists inhibit food intake. In this

NPY Y1 receptors in the dorsal periaqueductal gray matter regulate anxiety in the social interaction test
Autor: Jaanus Harro, Ants Kask, Lembit Rägo
Publikováno v: Europe PubMed Central
WE have reported previously that the NPY Y 1 receptor antagonist BIBP3226 applied into the dorsal periaqueductal gray matter (DPAG) has an anxiogenic-like effect in the elevated plus-maze test in rats. In the present study the effects of neuropeptide
