    Description / Table of Contents: Zusammenfassung Leberstanzcylinder, gewonnen durch Blindpunktion, wurden mit (4-14C)-Testosteron und (1,2-3H)-Δ4-Androstendion inkubiert und die Interkonversion sowie der Katabolismus dieser Androgene in vitro mit Hilfe einer radiogaschromatographischen Methode untersucht. Es zeigte sich, daß Testosteron durch histologisch normales und cirrhotisches Lebergewebe in der gleichen Größenordnung abgebaut wurde, durch Fettlebergewebe dagegen in geringerem Ausmaß. Der Abbau von Δ4-Androstendion durch normales Lebergewebe von Frauen war etwa 3mal größer als von Männern; auch die cirrhotische Leber von Männern baute mehr Δ4-Androstendion ab als die normale. Die Interkonversion von Testosteron in Δ4-Androstendion war durch normales Lebergewebe von Männern wesentlich höher als von Frauen. Abgebaut wurde Testosteron und Δ4-Androstendion mehr zu 5β-hydrierten Metaboliten als zu 5α-hydrierten Verbindungen.
    Notes: Summary Human liver tissue obtained by needle biopsy was incubated with (4-14C)-testosterone and (1,2-3H)-androst-4-enedione and the interconversion and catabolism of these androgenic hormones were investigated by a radio-gas chromatographic method. The rate of metabolism of testosterone in histologically normal hepatic tissue was as high as in cirrhotic tissue, while the rate of metabolism in fatty liver was lower. The catabolism of androst-4-enedione in normal liver tissue of women was three times higher than in that of men; metabolism of androst-4-enedione in cirrhotic tissue was also higher than in normal tissue. The interconversion of testosterone to androst-4-enedione by normal tissue of men was much higher than in women. Testosterone and androst-4-enedione catabolism to 5β-metabolites was greater than that to 5α-metabolites.
