In the present study, the effect of chronic treatment with venlafaxine on beta1 and 5-HT2 receptor populations was examined in the frontal cortex of olfactory bulbectomised (OB) and sham operated (SO) animals. The effect of these drugs on the behaviour of the animals on the elevated plus maze and the "open field" was also assessed. Removal of the bulbs… (More)
The realisation that pindolol may accelerate the effects of some antidepressant drugs in clinical trials has added extra impetus to the search for faster acting antidepressants. Currently, no animal model of depression can identify potential faster acting antidepressant drugs or drug combinations. In this study, we investigate the effects of combining… (More)
The study was designed to assess the potential antidepressant properties of the 5-HT1A receptor agonist, (+)-S-20499 (10 mg kg(-1) i.p.) in the olfactory bulbectomised (OB) rat. Following 2 weeks of treatment, the rats were tested in the elevated plus maze and the "open field". A characteristic hyperactive response was evident in the OB animals in the "open… (More)
5-HT1A receptor antagonists have recently been shown to accelerate the effects of some antidepressant drugs in clinical trials. In this study we investigate the effects of combining a full antagonist at the 5-HT1A receptor, WAY 100635 (0.2 mg/kg, SC) with the selective serotonin reuptake inhibitor (SSRI) paroxetine (5 mg/kg. SC) in the olfactory… (More)
Muscle lipid increases with high-fat feeding and diabetes. In trained athletes, increased muscle lipid is not associated with insulin resistance, a phenomenon known as the athlete's paradox. To understand if exercise altered the phenotype of muscle lipid, female C57BL/6 mice fed CTL or high-fat diet (HFD for 6 or 18 weeks) were further divided into… (More)
The olfactory bulbectomised (OB) rat is being increasingly used as a model of impaired learning and mnemonic functioning. In this study the model has been utilised to determine the effect of the acetylcholinesterase inhibiting compounds tacrine and physostigmine on spatial working memory deficits associated with the OB rat. One-hundred and twenty male rats… (More)
Racemic 7-hydroxy-N,N-dipropylaminotetralin (7-OH-DPAT) shows greater affinity for limbic-selective dopamine D3 receptors than for more ubiquitous dopamine D2 receptors. R(+)-7-OH-DPAT was prepared and evaluated in radioreceptor assays using membranes of fibroblasts expressing the human dopamine D3 receptor as well as rat striatal membranes containing… (More)
This report presents white blood cell count findings for persons ages 1-74 years and differential leukocyte count findings for adults ages 25-Bureau of the Census, under a contractual agreement, participated in the design and selection of the sample and carried out the first stage of the field interviewing and certain parts of the statistical processing.
