18-Hydroxycorticosterone (18 Hydroxycorticosterone)

05/01/1995 - "Some of the prohormones, such as 18-hydroxycorticosterone, are elevated in adenomas. "

10/20/1985 - "Seven out of 8 patients with aldosterone-producing adenoma had above-normal serum 18-hydroxycorticosterone levels. "

03/01/1982 - "However, a few "aldosterone" and "18-hydroxycorticosterone" values for patients with essential hypertension and normal aldosterone excretion were also (moderately) increased. "
05/01/1980 - "Increased 18-hydroxycorticosterone responses to frusemide in essential hypertension."
03/01/1982 - "For distinguishing primary aldosteronism from essential hypertension, we use simple direct radioimmunoassays for "aldosterone" (aldosterone and other materials that react with the antibody to aldosterone) and "18-hydroxycorticosterone" (similarly) in unprocessed urine. "
05/01/1981 - "In the three subjects with non-tumorous hyperaldosteronism, plasma aldosterone and 18-hydroxycorticosterone concentrations were raised, and their responses to AII infusion resembled those found in essential hypertension and were different from those found in Conn's syndrome. "
02/01/2002 - "The strongly enhanced 18-hydroxycorticosterone and aldosterone formation observed in the mutants provides important information on a possible role of such amino-acid replacements in the development of essential hypertension. "

01/01/1982 - "The role of 18-hydroxycorticosterone in the etiology of hypertension is still unknown."
01/01/1984 - "Adrenal adenoma with 18-hydroxycorticosterone excess and hypertension: a variant of aldosteronomas."
01/01/1982 - "Increased excretion of 18-hydroxycorticosterone in patients with adrenal adenomas and hypertension."
07/01/1983 - "Three cases with hypertension, adrenal adenoma, elevated 18-hydroxycorticosterone but normal aldosterone values were observed. "
03/01/1982 - "Direct radioimmunoassays for "aldosterone" and "18-hydroxycorticosterone" in unprocessed urine, and their use in screening to distinguish primary aldosteronism from hypertension."

11/01/1996 - "The hormonal studies showed that the tumor produced 18-hydroxycorticosterone."
07/01/1969 - "18-Hydrocorticosterone biosynthesis in an aldosterone secreting tumor and in the surrounding nontumorous adrenal gland."
05/01/1996 - "Preoperative diagnosis was primary aldosteronism in 2, 18-hydroxycorticosterone producing adnoma in 1, pre-Cushing syndrome in 5, and nonfunctioning adrenal tumor in 1 patient. "
01/01/1993 - "Tumor tissues actively converted deoxycorticosterone and 18-hydroxy-11-deoxycorticosterone to 18-hydroxycorticosterone and aldosterone. "
10/03/1990 - "The tumor appeared to produce autonomously cortisol as well as corticosterone, 18-hydroxycorticosterone and aldosterone. "

12/04/1982 - "Selective hypoaldosteronism is defined as diminished production of aldosterone, and sometimes also of 18-hydroxycorticosterone, with otherwise intact adrenal function. "
07/01/1985 - "Studies of renin activation and regulation of aldosterone and 18-hydroxycorticosterone biosynthesis in hyporeninemic hypoaldosteronism."
07/01/1989 - "Percent increments of plasma 18-hydroxycorticosterone and plasma aldosterone above their baseline levels after angiotensin II infusions were low or somewhat low in the patients with hyporeninemic hypoaldosteronism and low in the patients with normoreninemic hypoaldosteronism. "
07/01/1989 - "To examine the nature of adrenal abnormalities in diabetic patients with hyporeninemic and normoreninemic hypoaldosteronism, responses of plasma 18-hydroxycorticosterone and plasma aldosterone to angiotension II infusions and ACTH injection were investigated in 8 diabetic patients with hyporeninemic hypoaldosteronism and 9 diabetic patients with normoreninemic hypoaldosteronism compared to 11 control subjects. "
07/01/1989 - "In both the patients with hyporeninemic and normoreninemic hypoaldosteronism, plasma 18-hydroxycorticosterone and plasma aldosterone were low, whereas plasma cortisol and plasma corticosterone were within normal ranges. "
