Biochem/physiol Actions

11β-Hydroxy-4-androstene-3,17-dione is a naturally occurring steroid that is primarily, if not strictly, produced in adrenal tissue. In diseases such as Cushing′s syndrome, adrenal-originated hyperandrogenism, and congenital adrenal hyperplasia, plasma 11β levels are very high. Plasma 11β concentration is very low in congenital 11-hydroxylase deficiency and adrenal insufficiency.

In order to gain a better understanding of adrenal steroid production in guinea pigs, adrenocorticotropin (ACTH) was administered to castrated adult guinea pigs and a series of C-21 and C-19 steroid levels were determined in both adrenals and plasma over

The effects of sex steroids on spermatogenesis and testicular androgen secretion were studied in juvenile (spermatogonia present in testes) African catfish. Fish were implanted with Silastic pellets containing 11-ketotestosterone (KT), 11beta-hydroxyandrostenedione (OHA), androstenetrione (OA), androstenedione (A), testosterone (T), 5alpha-dihydrotestosterone (DHT)

In this study, we investigated guinea pig adrenal steroidogenesis, specially, C19 steroid production. Analysis of adrenal steroids by high performance liquid chromatography and gas chromatography indicated the presence of androstenedione and 11β-hydroxyandrostenedione. Adrenal androstenedione and 11β-hydroxyandrostenedione levels were stimulated by

To determine whether the adrenal androgen 11 beta-hydroxyandrostenedione is a more sensitive and specific marker than dehydroepiandrosterone sulfate, we compared these serum androgens in 81 women with anovulatory hyperandrogenism before treatment, after corticotropin and corticotropin-releasing-factor stimulation, and after short- and
P Holownia et al.

In a longitudinal study of 82 children we found a gradual rise in median plasma concentrations of 11 beta-hydroxyandrostenedione (11 beta-OH-A4) from 2.5 to 6.4 nmol/l during childhood which was similar in both sexes. This could reflect changes in adrenal
