Anxiety is a key symptom of the cocaine withdrawal syndrome in human addicts, and it is considered to be one of the major factors in precipitating relapse to chronic cocaine abuse. Corticotropin-releasing factor (CRF) plays an important role in the pathophysiology of anxiety and depression, and it may also be involved in the acute behavioral and(More)
Objective: There are few large cohort studies available on the association of systemic and thyroid autoimmune diseases. In this study, we wished to determine the association of Hashimoto’s thyroiditis (HT) and Graves’ disease (GD) with systemic autoimmune diseases. Methods: One thousand five hundred and seventeen patients with systemic lupus erythematosus(More)
Corticotropin-releasing factor (CRF) may mediate some of the neuroendocrine and behavioral responses to cocaine. In this study, the distribution of CRF-like immunoreactivity (CRF-LI) was determined in the hypothalamus and in several extrahypothalamic brain regions after acute cocaine administration in handled rats. CRF-LI decreased dose-dependently with(More)
The possible involvement of different neurotransmitter systems in the anxiogenic action of cholecystokinin octapeptide sulphate ester (CCK-8) was investigated in rats. Intracerebroventricularly (i.c.v.) administered CCK-8 induced an anxiogenic response in an elevated plus-maze test. Pretreatment with dopaminergic, muscarinergic acetylcholine receptor(More)
The possible involvement of endogenous corticotropin-releasing factor (CRF) in the anxiogenic and pituitary-adrenal-axis-activating effects of cholecystokinin octapeptide sulfate ester (CCK 8) was investigated in rats. Intracerebroventricularly (i.c.v.) administered CCK 8 induced an anxiogenic response in an elevated plus-maze test, and enhanced the plasma(More)
Mild Cognitive Impairment (MCI), sometimes regarded as a prodromal stage of Alzheimer's disease, is a mental disorder that is difficult to diagnose. However, recent studies reported that MCI causes slight changes in the speech of the patient. Our starting point here is a study that found acoustic correlates of MCI, but extracted the proposed features(More)
The role of endogenous corticotropin-releasing factor (CRF) in the cocaine-induced corticosterone response was investigated by using the immunoneutralization and receptor blockade of endogenous CRF. Pretreatment with different dilutions (1:5, 1:10 and 1:20, i.c.v.) of CRF antibody and different doses of an antagonist for CRF receptors, alpha-helical CRF9-41(More)
Behavioural adaptation to and the effects of the neurohypophyseal peptide, oxytocin, on repeated treatment with cocaine were investigated in rats. The content of immunoreactive oxytocin in the plasma, hypothalamus and different limbic structures in the brain were also studied after treatment with cocaine, identical to that used in the behavioural(More)
During the follow-up of thyroid function of 151 patients with Hodgkin's disease in complete remission for at least 1 year, 26 cases of subclinical, 12 cases of manifest clinical hypothyroidism and 2 cases of hyperthyroidism (Graves-Basedow disease) were confirmed. Thyroid dysfunction was more frequent in patients who had undergone mantle or neck(More)
It has previously been demonstrated that cocaine stimulates the hypothalamic-pituitary-adrenal (HPA) axis through hypothalamic corticotropin-releasing factor (CRF) secretion. The role of different neurotransmitters in mediation of the cocaine-induced elevation of plasma corticosterone (CORT) were investigated in rats by using transmitter antagonists.(More)
