摘要: Summary Zinc has been determined with atomic absorption spectrophotometry in 1.460 specimens of human seminal plasma from 809 men. The mean concentrations was 133 μg/ml (range 1—621) and the relative frequency distribution showed a marked positive skewness. There no difference among samples different age groups (18—70 years). Zinc originates prostate gland it appears that determination this ion provides valuable information about secretory capacity provided due attention is paid to volume fructose concentration same specimen. No correlation noted between zinc sperm density, motility or morphology. reasons for are discussed. Human subjected gel chromatography on Sephadex G-50 recovered two peaks, one coinciding first protein peak, second having Kav 0.84. ratio peaks dependant upon content plasma. Zusammenfassung In Humanseminalplasmata von Mannern wurden Zinkgehalte mit Atomabsorption bestimmt. Der Mittelwert betrug einer Streuung 1—621. Die Frequenzverteilung ist rechts verschoben. Wir fanden keine Differenz der Verteilungsfrequenz verschiedenen Altersgruppen Jahre). Der Zinkgehalt des Seminalplasmas stammt aus Prostata und es scheint, daβ die Bestimmung Zink-Ionen eine Aussage uber sekretorische Funktion dieser Druse gibt, jedoch nur wenn Zinkwerte zu Volumen Fruktosekonzentration Relation gesetzt werden. Es konnte zwischen Spermatozoenzahl, Motilitat Morphologie gefunden werden. Grunde dafur diskutiert. Bei Chromatographie Humanseminalplasmen an wurde Zink zwei Fraktionen gefunden, 1. zusammen ersten Proteinfraktion, 2. bei einem Quotient beiden Zinkproteinfraktionen hangt ab. Resume Le ete recherche par spectrophotometrie d'absorption atomique sur echantillons de preleves chez hommes. La moyenne (valeurs extremes 1—621 μg/ml) et la courbe frequence montrait une obliquite marquee. Aucune dans frequences n'etait notee pour les provenant groupes differentes âges (18–70 ans). Le continent le humain proviant prostate. Il apparait que cet apporte capacite secretoire glande si l'on tient compte egalement du en meme echantillon. Aucune n'a remarquee entre densite spermique, motilite ou morphologie spermatozoides. Les raisons sent discutes. La chromatographie montre etait recueilli 2 pics; l'un coincide avec premier pic correspondant aux proteines, l'autre un Le rapport ces pics depend seminal.
