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.

Corticosterone Half-Life in Children
Archives of Pediatrics & Adolescent Medicine, 1964Corticosterone (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's dual metabolic actions
Life Sciences, 1989Corticosterone possesses two distinctly opposite metabolic actions. The actions are strictly dose-dependent and are linked to type I and type II corticosteroid receptor binding. These conclusions are drawn from continuous infusion studies where corticosterone yields a bitonic dose-response curve for body weight gain and feeding efficiency.

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 ...

3H-CORTICOSTERONE METABOLISM IN THE RAT
Acta Endocrinologica, 1969ABSTRACT 3H-Corticosterone was administered intravenously into two rats. After 80 min the animals were sacrificed and the radioactive material of the different tissues (intestine, liver, kidneys, lungs, adrenals, spleen and the remainder of the animal) was analyzed.

Comparative Biochemistry and Physiology Part A: Molecular & Integrative Physiology, 2003
Relationships between hormones and behaviour can be explored by altering endogenous hormone levels, often through implantation of silastic tubing or osmotic pumps filled with a hormone or its agonists or antagonists. However, organisms in sensitive life-history stages (such as pregnancy) may be adversely affected by the surgical procedures associated ...

General and Comparative Endocrinology, 2008
The question of whether changes in glucocorticoid concentrations reflect consistent changes in physiology associated with transitions between different stages of reproduction, or whether they reflect responses to environmental conditions, is one the central issues in field endocrinology studies.
