    Notes: Summary The impact of aggressive chemotherapy on reproductive and endocrine gonadal function was prospectively studied in 44 patients with germ cell tumors. Diagnostic procedures to determine gonadal toxicity consisted of hormone determinations, semen analyses, interviews with a standardized questionnaire, and gonadal histology. After chemotherapy all patients showed elevated serum levels of follicle-stimulating hormone (FSH) and azoospermia due to germ cell and stem cell loss. Recovery of spermatogenesis, as indicated by normalization of serum FSH levels and sperm density, occurred in 77% of the patients 25–60 months after cessation of chemotherapy. In all patients serum testosterone and luteinizing hormone (LH) values remained within normal limits after therapy indicating resistance of Leydig cells to cytotoxic drugs. Three patients fathered four healthy children after completion of chemotherapy. These data suggest significant reproductive dysfunction in all men treated for germ cell tumors. However, most patients showed late and complete recovery of spermatogenesis. In contrast, endocrine gonadal function was unaffected after chemotherapy in all patients. FSH and LH are feasible markers to assess drug-induced gonadal toxicity.

    Description / Table of Contents: Abstract. Multicentric reticulohistiocytosis (MRH) is a rare disorder of skin and joints, and its aetiology is unknown. We describe a male patient who had first developed osteoblastic lesions of the skeleton in 1976 at the age of 59 years. Three years later, he presented with multiple papular and nodular skin lesions, predominantly on the limbs and upper trunk, and 4 years later he developed painful arthropathy. In 1988 skin examination showed multiple brownish-red papulo-nodules, some of which, at mechanically stressed areas, were ulcerated. The patient complained of pronounced arthrotic disorders with reduced joint mobility. Examination of biopsy specimens from active skin lesions demonstrated extensive numbers of macrophages with partial confluence to giant cells with typical ground-glass cytoplasm. Electron microscopy revealed phagocytosis of collagen-like structures. Examination of bone marrow biopsy specimens revealed diffuse infiltration by histiocytic cells. The diganosis made was therefore MRH. The patient was treated for several years with different therapeutic regimens, including azathioprin, dapsone, prednisolon, chlorambucil and cyclophosphamide, and complete remission of skin lesions and of bone marrow infiltration was observed. However, a myelodysplastic syndrome with refractory anaemia and ring sideroblasts developed, which is generally understood to be a preleukaemic condition. Myelodysplastic syndromes commonly develop between 3 and 10 years after the start of a therapy with antineoplastic agents.
    Notes: Zusammenfassung. Die multizentrische Retikulohistiozytose (MRH) ist eine seltene, ätiologisch ungeklärte Erkrankung der Haut und des Skeletts mit Bevorzugung der Gelenke. Bei dem vorgestellten männlichen Patienten fanden sich 1976 im Alter von 59 Jahren erstmalig osteoblastenaktive Verdichtungen im Skelett. Drei Jahre später entwickelten sich multiple Papeln und Knoten an den Extremitäten, und nach 4 Jahren traten Gelenk- und Knochenschmerzen auf. Bei der Erstvorstellung 1988 fanden sich multiple, livide und z. T. bräunlich pigmentierte Knoten an der Haut, die an mechanisch belasteten Arealen exulzeriert waren. Weiterhin fielen erhebliche arthrotische Veränderungen mit Bewegungseinschränkungen der großen Gelenke auf. Der histologische Befund der Haut zeigte Makrophagen, z. T. zu Riesenzellen konfluierend mit typischem glasigem Zytoplasma. Elektronenmikroskopisch war Kollagenphagozytose nachweisbar. Somit konnte die Diagnose einer MRH gestellt werden. Im Knochenmark fand sich eine diffuse Vermehrung histiozytärer Zellen. Über mehrere Jahre wurde der Patient in unterschiedlichen Therapieprotokollen mit Azathioprin, Dapson, Prednisolon, Chlorambucil und Cyclophosphamid behandelt. Darunter kam es zu einer vollständigen Rückbildung der Tumoren der Haut. Auch Knochenmarksinfiltrate waren nicht mehr nachweisbar, dafür trat jetzt eine refraktäre Anämie mit Ringsideroblasten als Ausdruck eines myelodysplastischen Syndroms (MDS) auf, das als Präleukämie aufgefaßt wird. Myelodysplastische Syndrome entwickeln sich häufig 3 – 10 Jahre nach Chemotherapie.

    Notes: The two-scale-factor universality hypothesis of critical phenomena is used to estimate the liquid/liquid interfacial tension near the critical point of binary alloys with miscibility gap. Experimental results of measurements of the correlation length of local concentration fluctuations (data for the systems cadmium/gallium and sodium/lithium taken from the literature), and experimental results of measurements of the temperature dependence of the molar heat capacity at constant pressure (data for the system bismuth/gallium taken from the literature) are used for this illustration.

    Notes: The pendant drop method and the capillary rise method are used to measure the interfacial tension σ of 2,6-dimethyl pyridine(2,6-lutidine)/water mixtures near the lower critical point. It is found that at temperatures 0.2 K≤(T−Tc)≤1.5 K the temperature dependence of σ is represented by a power law of the form σ=σ0 tμ (t=(T−Tc)/Tc) with μ=(1.25±0.01) and σ0=(32.4±0.6) mN m−1. The value of μ is consistent with the theoretically expected universal value of μ=1.26. At large temperature differences σ increases slower than expected by the power law. The values of the amplitude ratios Rσ,ξ+[=σ0(ξ0+)2/(kBTc)] and Rσ,A+[=(Av,0/kB)2/3(kBTc/σ0)] calculated from the experimental data [correlation length of local concentration fluctuations, ξ0+=(0.230±0.009) nm] and Av,0 (heat capacity per unit volume at constant pressure; Av,0=1.81 J cm−3 K−1) are consistent with accepted values. This indicates that the interfacial tension measurements are free from large systematic errors. The value of a2 (a, capillary constant) determined with the pendant drop method as well as with the capillary rise method agree with each other within the uncertainty of the measurements in a temperature range (T−Tc)≤7 K. The capillary rise data is analyzed by assuming that the contact angle θ of the lower water rich phase at the capillary wall is zero (θ=0). The data follows the same curve as that obtained with the pendant drop method in a temperature range (T−Tc)≤25 K. From these findings it is concluded that the water rich (lower) phase wets the wall of the glass capillary completely at least up to temperature differences (T−Tc)≤7 K. A wetting transition cannot be detected in that temperature range.
