    Description / Table of Contents: Zusammenfassung Geprüft wurde ein embryonales Organkultursystem für carcinogene Untersuchungen in vitro. Dabei fanden murine Sarkomaviren (MSV-M) und 3-Methylcholanthren (MCA) Verwendung. Die Behandlung wurde am embryonalen Nierengewebe von CBA/H-T6 Mäusen durchgeführt. MSV-M Gabe führte weder zu einer Hemmung der Glomerulogenese noch zu einer frühen malignen Transformation. Die Behandlung des gleichen Gewebes mit MCA verzögerte dagegen die Glomerulogenese erheblich, führte jedoch ebenfalls nicht zur Induktion einer frühen malignen Transformation. Erst nach sehr langen Überlebenszeiten in vitro entstanden bei je einer MSV-Mund MCA-behandelten und bei zwei unbehandelten Kulturen transformierte Zellen, die nach Transplantation auf neugeborene CBA/H-T6 Mäuse malignes Wachstum zeigten. Auffällig waren dabei die histologisch unterschiedlichen Differenzierungsformen der Tumoren.
    Notes: Summary With the aim of expanding knowledge on the pathogenesis of nephroblastomata, an embryological organ culture system (Grobstein, 1956) was tested for its applicability to in vitro carcinogenesis experiments by using murine sarcoma virus (MSV-M) and 3-methylcholanthrene (MCA). Treatment of CBA/H-T6 mouse metanephrogenic mesenchyma with MSV-M at the pretubular stage neither disturbed the glomerulogenesis nor induced rapid malignant transformation. Treatment of the same tissues with MCA considerably inhibited the glomerulogenesis but failed to also induce rapid malignant transformation. However, one MSV-M, one MCA and two untreated cultures showed malignant transformation after prolonged survival in vitro and produced different histological types of tumours upon transplantation into newborn CBA/H-T6 mice.

    Notes: Abstract Low cycle fatigue was considered in relation to back-stress hardening. Cyclic stress-strain behaviours under controlling strain and stress conditions were investigated for a quenched and tempered low alloy steel which contained cementite particles. The cyclic stress-strain states obtained by the two prescribed tests were uniquely described using a parameter which reflected the cumulative reversible plastic work associated with the back-stress hardening. It was suggested that the effect of back-stress hardening on cyclic deformation should appear directly on the cyclic stress-strain curves defined as the loci of the tips of stable hysteresis loops. The initial slopes of the cyclic stress-strain curves for several steels were demonstrated to coincide with the theoretical work-hardening rates calculated on the basis of back-stress hardening due to the included carbide particles. Finally, the Manson-Coffin law was explained from the view that the surface damage would progress in parallel with the structure change in the bulk according to the persistency of slips resulting from the reversible back-stress hardening.
