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%.

Rat and Mouse Brain Corticosterone
Endocrinology, 1972A 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.

Repeatability of baseline corticosterone concentrations
General and Comparative Endocrinology, 2008One major assumption for endocrine studies is that hormone titers are consistent within an individual so that if hormone titers are low relative to the cohort on one day, they are relatively low compared to the cohort on other days. This is an especially important assumption for most field studies where researchers may have access to an individual ...

Unlike normal rats, adrenalectomized rats do not voluntarily drink sweet saccharin solutions. To test whether this is a function of corticosterone in the circulation, and if corticosterone also increases the impetus for drinking saccharin after a period of withdrawal, we performed the following experiments.

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.

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.

Corticosterone and corticosterone-21-sulphate production in man
Journal of Steroid Biochemistry, 1969Abstract 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.

Glucocorticoids can play a critical role in modulating life-history trade-offs. However, studying the effects of glucocorticoids on life-history often requires experimentally elevating plasma glucocorticoid concentrations for several weeks within normal physiological limits and without repeated handling of the animal. Recently, implants made of beeswax

CORTICOSTERONE was isolated from adrenal gland extracts almost simultaneously by Kendall (i, 2) and Reichstein (3). Its chemical configuration was also eluci-dated independently by these workers (4, 5). This substance occurs in gland extracts in as great if not greater concentration than any of the other active steroids thus far obtained.
