(kōr'ti-kō-ster'oyd)
A steroid produced by the cortex of the suprarenal gland.

adrenal steroids,

adrenal

1. near the kidney.
2. of or produced by the adrenal glands.
3. an adrenal gland.

adrenal cortex
the outer part of the adrenal gland made up of an external zona glomerulosa, a deeper zona fasciculata and a zona reticularis. It produces three main groups of hormones, the glucocorticoids which are concerned with increasing blood glucose levels, the mineralocorticoids concerned with the maintenance of electrolyte levels in the extracellular fluid, and androgens which have the same masculinizing effect as the hormone testosterone produced by the testis. Called also adrenal gland cortex. See glucocorticoid, mineralocorticoid, androgen.

adrenal hyperplasia-like syndrome
a congenital abnormality of adrenal steroidogenesis reported in dogs which results in hyperprogestinism and hyperandrogenism. Clinical signs include bilaterally symmetrical alopecia resembling that seen with other endocrinopathies.
adrenal insufficiency
hypofunction of the adrenal gland, particularly the cortex, leading to signs of weakness and loss of sodium, chloride and water. See also primary hypoadrenocorticism.
adrenal medulla
a glandular extension of the effector fibers of the sympathetic nervous system that releases into the bloodstream the hormones epinephrine (adrenaline) and norepinephrine (noradrenaline). When the sympathetic nervous system is stimulated the adrenal medulla responds also and its hormones are carried via the bloodstream to cause increases in cardiac output and metabolic rate, vasoconstriction and reduction of gastrointestinal peristalsis. The hormones have similar functions but epinephrine is removed from the bloodstream more slowly and has a more prolonged effect. Called also adrenal gland medulla.
Adrenal medullary hormones are not essential to life. Hypersecretion, such as occurs in some functional pheochromocytomas, causes tachycardia, edema and cardiac hypertrophy.
adrenal steroids
cortisol, corticosterone, cortisone, 11-dehydroxycortisone, desoxycorticosterone, 17-hydroxy-11-desoxycorticosterone, aldosterone, the adrenal corticoids from the adrenal cortex. Called also corticosteroids.

However, ROC curve analysis indicated considerably improved diagnostic utility for subtype discrimination when all 15 adrenal steroids were considered (Fig.
34), who reported measurements of 10 adrenal steroids, including aldosterone, in adrenal venous plasma of 9 patients with primary aldosteronism before and after corticotropin stimulation.
Fourth, a model that predicts the response of the major adrenal steroids [e.
However, ovarian and testicular steroidogenesis does not include the metabolic pathways for the major adrenal steroids, aldosterone and Cortisol.
A much smaller number of chemicals have been evaluated for effects on other endocrine systems such as androgens and adrenal steroids.
Lead exposure early in development has been shown to disrupt multiple endocrine systems, including the gonadal steroids (103), adrenal steroids (104,105), and thyroid hormones (105).
Because interfering substances and the degree of interference vary among commercially available immunoassays, reference intervals for adrenal steroids are often method-specific and cannot be used interchangeably (18-23).
Some states have been reluctant to screen for CAH because the most commonly used assays have poor positive predictive values, especially in preterm and acutely ill neonates, in whom the adrenal steroids are physiologically increased.
He joined the neuroendocrine research group in the Institute of Physiology in Pecs, where he became involved in research projects investigating the interactions of neuronal peptides, adrenal steroids, and the central nervous system's adaptation processes.
The majority of these articles dealt with topics in pediatric endocrinology, particularly with the urinary excretion of adrenal steroids.
The diagnosis is usually made by finding the characteristic pattern in the adrenal steroid profile with confirmation by molecular mutation analysis.
