    Notes: Summary In this study it is demonstrated, that incubation of both, bile acids and free fatty acids with LP-X, the abnormal plasmalipoprotein found in patients suffering from cholestasis or LCAT-deficiency, results in striking alterations of the physico-chemical and immunological properties of LP-X: 1. The cathodic mobility in agar is changed into an anodic migration of the material. 2. The unique appearance of LP-X on electronmicrographs is altered by the incubation revealing fingerprint like structures. 3. The albumin portion of LP-X becomes immunologically detectable. 4. Bile salts cause marked changes in the hydrated density of the material as determined by zonal ultracentrifugation. 5. In vitro incubation of LP-X with postheparin plasma causes a complete disappearance of LP-X as judged by its typical migration on agar electrophoresis. All these alterations can be prevented or reversed by the addition of albumin in appropriate concentrations. These findings are important in the light of studies designed to investigate the catabolic action of plasma lipolytic enzymes on LP-X, as well as for follow up studies of LP-X concentrations during the course of disease.

    Description / Table of Contents: Summary The theory of parameter and combination resonances is applied to rotor systems having asymmetric elements. The number of formal possible resonances of first order is usually given by f 2, when f is the number of degrees of freedom. The number of resonances can be essentially reduced representing the rotor system by inertial as well as by rotating coordinates. Resonance frequencies must appear in both representations. By this, for a rotor system having asymmetric shaft stiffness and asymmetric bearings, the number of possible resonances is reduced to f 2/4. While parameter resonances only arise in the case of critical speeds of forward precession, combination resonances may only appear summing critical frequencies of a forward and of a backward precession.
    Notes: Übersicht Für Rotorsysteme mit Unsymmetrien wird die Theorie der Parameter- und Kombinationsresonanzen angewandt, um die kritischen Frequenzen der Parametererregung festzustellen. Die Anzahl der formal möglichen Resonanzfrequenzen 1. Ordnung, die bei einem Rotorsystem mit f Freiheitsgraden bei üblicher Untersuchungsweise f 2 beträgt, wird wesentlich reduziert, indem die mathematische Beschreibung sowohl im inertialen als auch im mitdrehenden Koordinatensystem erfolgt. Nur die in beiden Darstellungen gleichen Resonanzfrequenzen sind interessant. Für ein Rotorsystem mit Wellen- und Lagerunsymmetrien ergeben sich Parameterresonanzen nur für Gleichlauf-Frequenzen; die Kombinationsresonanzen treten nur in Summenform zwischen je einer Gleichlauf- und einer Gegenlauf-Frequenz auf. Die Anzahl der möglichen Instabilitäten hat sich auf f 2/4 verringert.

    Notes: Summary The parents of a child with the clinical symptoms of Ehlers-Danlos syndrome type VI were identified as third-degree cousins. Biochemical analysis of the dermis of the patient revealed a complete lack of hydroxylysine in the dermal collagen. The dermis of both parents contained only half the amount of hydroxylysine found in healthy individuals. Hydroxylation of prolyl residues was normal in the skin of the patient and his parents. Investigation of the collagen synthesized by fibroblasts derived from the skin of the patient showed a normal proportion of type I and type III collagen. However, while hydroxylation of prolyl residues was normal in type I and type III collagen, hydroxylation of lysyl residues was markedly lower than normal in both type I and type III collagen.

    Notes: Summary The present study describes for the first time the use of the fluorescent dye sulfonefluorescein for intravital microscopy and microphotometry on the renal surface of rats. With help of this dye tubular secretion can be observed in mammalian kidney in vivo. Tubular secretion can further be quantified with microphotometrical measurements. The molecular structure of sulfonefluorescein is closely related to phenol red, which is known for its tubular secretion. Clearance experiments also show a secretion of sulfonefluorescein. The secretion can be inhibited by probenecid. Ureter ligation causes a strong increase in tubular concentration of the dye. After a temporary ischemia dye accumulation in tubular lumen is greatly reduced.
