BACKGROUND There are breed differences in several blood variables in healthy dogs. OBJECTIVE Investigate breed variation in plasma endothelin-1 (ET-1) concentration, plasma renin activity, and serum cortisol concentration. ANIMALS Five-hundred and thirty-one healthy dogs of 9 breeds examined at 5 centers (2-4 breeds/center). METHODS Prospective observational study. Circulating concentrati...
Fisheries Department, Faculty of Natural Resources, University of Guilan, Sowmeh Sara,1144, Iran ABSTRACT This study was conducted the effect of stress on blood glucose and cortisol levels in cultured great sturgeon. Blood sampling was done and then water level decreased to the half in experimental tanks. The fish were exposed in that situation and second blood sampling was taken after ...
BACKGROUND The purpose of this study was to validate a commercially available enzyme-linked immunosorbent assay (ELISA) developed for measuring free cortisol in human saliva and total cortisol concentration in diluted human serum, for its applicability in measuring cortisol concentration in pig saliva. Collection of saliva is less stressful than e.g. blood sampling, and is a non-invasive method...
Natural and synthetic glucocorticoids (GCs) have been used for decades to suppress inflammation. In this paper, we re-examine the role of the endogenous GC, cortisol, as a primary homeostatic regulator of the human inflammatory response to injury. Our data show that cortisol regulation of innate immunity can be both pro-inflammatory and anti-inflammatory. Using a human model of in vivo cortisol...
The purpose of this research was to evaluate the serum cortisol and immunoglobulin-A (IgA) responses to maximal progressive exercise in elite male and female athletes. Twenty-four elite athletes who had experience in national team or played on league championship voluntarily participated in this study ( ages: 22.46±3.37 yr, height: 175.54±8.68 cm, weight: 70.02±13.60 kg, body fat percent: 15.86...
BACKGROUND There are no clear treatment guidelines for dogs with clinically well-regulated hyperadrenocorticism in which serum cortisol concentrations before and after an ACTH stimulation test performed 3-6 hours after trilostane administration are < 2.0 μg/dL. OBJECTIVE To determine if serum cortisol concentrations measured before (Pre1) and after (Post1) ACTH stimulation at 3-6 hours after ...
BACKGROUND A syndrome of relative adrenal insufficiency has been identified in septic humans, and is associated with hypotension and death. Relative adrenal insufficiency is generally associated with basal serum cortisol concentration within or above the reference range and a blunted cortisol response to adrenocorticotropic hormone administration. It is unknown whether relative adrenal insuffic...
BACKGROUND Cortisol is presumed to be a risk factor for stress- and age-related disorders, such as depressive disorder and Alzheimer's disease (AD). The aim of this study was to investigate the association of plasma cortisol concentration with AD in presence or absence of comorbid depressive symptoms. MATERIAL AND METHODS Plasma cortisol concentration was measured in 80 AD patients (35 of the...
Radioimmunoassay (RIA) is the "gold standard" method for evaluation of serum cortisol concentration. The VIDAS cortisol test is an enzyme-linked fluorescent assay designed for the MiniVidas system. The aim of this study was to compare the VIDAS method with RIA for measurement of bovine serum cortisol concentration. Cortisol concentrations were evaluated in 40 cows using both VIDAS and RIA metho...
