A radioimmunoassay for plasma corticosterone

Steroids, 1972
Abstract 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%.

Enzyme immunoassay of corticosterone

Journal of Steroid Biochemistry, 1979
Abstract 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.

Corticosterone rhythm of mouse adrenal in relation to serum corticosterone and sampling

American Journal of Physiology-Legacy Content, 1959
Under 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 ...

The release of corticosterone and a corticosterone-binding protein by incubated rat adrenal slices

The Journal of Steroid Biochemistry and Molecular Biology, 1991
Stimulation 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.

Cannabinoid effects on plasma corticosterone and uptake of 3H-corticosterone by mouse brain

European Journal of Pharmacology, 1978
The 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.

BINDING OF CORTICOSTERONE IN RAT LIVER

Journal of Endocrinology, 1970
SUMMARY 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.

Corticosterone Half-Life in Children

Archives of Pediatrics & Adolescent Medicine, 1964
Corticosterone (4-pregnene-11 β, 21 diol-3,20-dione; compound B) is a major product of adrenal steroidogenesis in most animal species. 1 In man, it is present in peripheral blood 2-12 and in adrenal vein effluent 3,13-15 in quantities second only to cortisol.

Corticosterone and corticosterone-21-sulphate production in man

Journal of Steroid Biochemistry, 1969
Abstract From isotope dilution experiments in which 3H-corticosterone-21-sulphate (B-S) or 14C-corticosterone (B) were injected intravenously into normal men and the specific activities of urinary metabolites were measured, it was estimated that 1.7–3.3 mg of B and less than 0.2 mg of B-S were secreted per day.

Fecal corticosterone metabolites and plasma corticosterone in Japanese quail selected for low or high plasma corticosterone responses to brief restraint

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.

Rat and Mouse Brain Corticosterone

Endocrinology, 1972
A procedure has been developed for determining the amount of corticosterone in mouse and rat brains. Recovery of corticosterone was shown to be between 80 and 90%. Using this procedure, values for basal levels of brain corticosterone have been obtained.
