cortisol(redirected from cortisol:corticosterone ratio)
Also found in: Dictionary, Thesaurus, Encyclopedia.
a hormone from the adrenal cortex, the principal glucocorticoid; called also 17-hydroxycorticosterone and, pharmaceutically, hydrocortisone. A synthetic preparation is used for its antiinflammatory actions.

The principal glucocorticoid produced by the zona fasciculata of the adrenal cortex. It promotes gluconeogenesis and lipolysis, suppresses protein synthesis, inhibits inflammatory and immune responses, and has mild mineralocorticoid (for example, hypernatremic, kaliureteric, antidiuretic) effects. Most plasma cortisol is bound to transcortin and albumin. Synthetic cortisol administered as a drug is usually known by the alternative name hydrocortisone.

cortisol(kôr′tĭ-sôl′, -zôl′, -sōl′, -zōl′)
A steroid hormone, C21H30O5, produced by the adrenal cortex, that regulates carbohydrate metabolism, maintains blood pressure, and is released in response to stress; hydrocortisone.

cortisolHydrocortisone A major hormone produced by the adrenal cortex, which is the primary glucocorticoid secreted by the adrenal gland in response to ACTH stimulation or stress; cortisol has anti-inflammatory activity, and is involved in gluconeogenesis, glycogen storage in the liver, immune regulation, mediation of physiologic stress responses, Ca2+ absorption, secretion of gastric acid and pepsin, conversion of proteins to carbohydrates, and nutrient metabolism; it is secreted in a diurnal pattern–levels rise early morning, peak ± 8 am, and flatten in the evening, diurnal cycling is lost in Cushing syndrome; cortisol secretion is influenced by heat, cold, infection, trauma, excercise, obesity, intercurrent illness ↑ in Adrenal CA, Cushing's disease, ectopic ACTH, ectopic CRH, hyperthyroidism, depression, alcoholism, substance abuse, anorexia, heavy smoking, CA, ulcers, DM, chronic pain, strokes, CVA, Parkinson's disease, MS, psoriasis, acne, eczema, stress, aging, Alzheimer's disease, AIDS, space adaptation syndrome ↓ in Addison's disease, hypopituitarism, hypothyroidism.

A hormone released by the cortex (outer portion) of the adrenal gland when a person is under stress. Cortisol levels are now considered a biological marker of suicide risk.
