Prasteron

BeschreibungDehydroepiandrosterone(DHEA) is an endogenous steroid hormone that is secreted primarily by the adrenal gland and is the most abundant sex steroid. It is a neurohormone; small quantities of DHEA are produced in the brain and declines in serum and CSF with age. (Knopman and Henderson, 2003). Metabolites of DHEA include androstenedione , which subsequently may be metabolized to testosterone or estrone which is an estradiol precursor. In addition to serving as an intermediate in the biosynthesis of sex steroids, DHEA directly modulates a number of cellular and nuclear receptors.

OccurrenceDHEA is naturally occurring in yam (see Wild Yam, p. 596-597).

VerwendenDehydroepiandrosterone (DHEA) is a major C19 steroid produced by the adrenal cortex. It is a major secretory steroidal product of the adrenal gland; secretion progresively declines with aging. May have estrogen-or androgen-like effects depending on the hormonal milieu. Intracellularly converted to androstenedione. It is used in treatment of menopausal syndrome. People living with HIV may be interested in taking DHEA for a variety of reasons, including treatment of depression, increasing bone density, decreasing arterial plaques, improvement of immune function with HIV, increased memory, and increased muscle strength.
