Lactogenic hormone activity was first observed in bovine pituitary
extracts by Stricker and Griiter in 1928, working in Bouin's
laboratory in Strasbourg. Since that time prolactin has been shown
to exist in anterior pituitary extracts of almost all vertebrate
species investigated. Although its biology was extensively studied
in many mammalian species, the existence of prolactin in the human
was generally doubted, despite the positive evidence produced by
such researchers as Pasteels. This can partly be explained by the
fact that human growth hormone isolated in 1961, is itself a potent
lactogen, in contrast to nonprimate growth hormones, and is present
in the normal human pituitary in much greater amounts than
prolactin. As a result there was a lag of nearly 10 years until
prolactin was unanimously accepted as a hormone of the human
pituitary, separate from human growth hormone. In 1970 new bioassay
techniques permitted the demonstration of prolactin bioactivity in
the serum of postpartum women and galactorrhea patients, and
chromatographic methods led to the isolation and purification of
human prolactin allowing the establishment of a specific
radioimmunoassay for this hormone. This opened the road to the
understanding of prolactin physiology and pathophysiology in the
human, which has revolutionized clinical neuroendocrinology and
reproductive endocrinology. Particularly hyperprolactinemia has
turned out to be one of the most common endocrine syndromes.
Die HyperprolaktinAmiesyndrome gehAren zu den facettenreichsten
endokrinen Erkrankungen. Innerhalb der gynAkologischen
Endokrinologie wird die HyperprolaktinAmie als Ursache von
ZyklusstArungen bei ca. 15 % der Frauen mit AmenorrhA gefunden. Bei
MAnnern gehArt die HyperprolaktinAmie zu den wichtigsten
somatischen Ursachen der Impotenz. AuAerdem spielt sie als
Begleiterkrankung anderer endokriner StArungen eine Rolle. Das
vorliegende Buch gibt eine Aoebersicht A1/4ber die heute
akzeptierten theoretischen, klinischen und therapeutischen Konzepte
bei der HyperprolaktinAmie. VAllig neu ist dabei die Integration
eines Konzeptes A1/4ber psychologische Befunde. Das Buch ist fA1/4r
interessierte A"rzte, welche Patienten mit
HyperprolaktinAmiesyndromen behandeln, eine unerlAAliche
Informationsquelle.
