Determination of endogenous corticosterone in rodent’s blood, brain and hair with LC–APCI–MS/MS
Journal of Chromatography B: Analytical Technologies in the Biomedical and Life Sciences, 2015 Endogenous corticosterone in rodent's hair would be a potential biomarker to assess the response of the hypothalamus-pituitary-adrenal axis to chronic stress.

Corticosterone in Chicken Eggs
Annals of the New York Academy of Sciences, 2005Abstract: Birds are discussed as models for prenatal stress. In this study, several experiments were conducted to gain basic knowledge of if, how, and when maternal adrenocortical activity is reflected by corticosterone concentrations in the egg. Radiolabeled corticosterone was administered to 10 laying hens to investigate the uptake into as well as ...

Journal of Steroid Biochemistry, 1983
If micro-sampling techniques are used in conjunction with a highly sensitive radioimmunoassay procedure, it is possible to obtain repeated rapid measurements of plasma corticosterone concentrations from unanesthetized rats. Such a procedure reveals the existence of rapid corticosterone pulses with a duration of less than 60 s and amplitudes as great as

Enzyme immunoassay of corticosterone
Journal of Steroid Biochemistry, 1979Abstract Enzyme immunoassay of corticosterone was developed using alkaline phosphatase as a labelling enzyme. Serum corticosterone was measured by this system after the extraction and purification of corticosterone by Sephadex LH-20 column chromatography.

A radioimmunoassay for plasma corticosterone
Steroids, 1972Abstract A radioimmunoassay for plasma corticosterone has been developed. Antiserum against corticosterone was produced in rabbits immunized with corticosterone -21- hemisuccinate conjugated to bovine serum albumin. The assay was practical and reliable. The coefficient of variation between assays was ± 23% and among assays was ± 8%.

Corticosterone rhythm of mouse adrenal in relation to serum corticosterone and sampling
American Journal of Physiology-Legacy Content, 1959Under conditions standardized for light-synchronized periodicity analysis the corticosterone content of mouse adrenals undergoes significant 24-hour periodic changes. In mature males of the B1 stock, glandular hormone content fluctuates by approximately 50% around its day-mean, accounting amplitude-wise for about one-half of the periodic change in ...

Cannabinoid effects on plasma corticosterone and uptake of 3H-corticosterone by mouse brain
European Journal of Pharmacology, 1978The effects of three cannabinoids, 11-hydroxy-delta9-tetrahydrocannabinol (11-HO-delta9-THC), delta9-THC and cannabinol (CBN), ranging in behavioral activity from high to low, were studied on two aspects of pituitary--adrenal function. Plasma corticosterone levels were used as an index of adrenocorticotropic hormone (ACTH) release.

The release of corticosterone and a corticosterone-binding protein by incubated rat adrenal slices
The Journal of Steroid Biochemistry and Molecular Biology, 1991Stimulation of incubated rat adrenal slices with ACTH(1-24) resulted in an increase in the release of both corticosterone and specific corticosterone-binding protein into the incubation medium. The release of corticosterone and binding protein was dose and calcium dependent with adrenals from animals pretreated with betamethasone.

Domestic Animal Endocrinology, 2012
Fecal corticosterone metabolites and plasma corticosterone in Japanese quail selected for low- or high-plasma corticosterone responses to brief mechanical restraint (low- and high-stress lines), and in a line of unselected quail, were measured in this study.

BINDING OF CORTICOSTERONE IN RAT LIVER
Journal of Endocrinology, 1970SUMMARY The binding characteristics of corticosterone by rat liver were studied by a displaceable binding technique. The binding of corticosterone to protein fractionated by gel filtration and density gradient centrifugation has been carried out as a preliminary determination of the nature of the binding sites.
