    Zusammenfassung 1. Unsere statistischen Untersuchungen stützen sich auf 395 Leichen mit bekannter Wasserzeit und -temperatur. 2. Fäulnis, Autolyse und Mazeration laufen bei Wasserleichen in einer bestimmten gesetzmäßigen Reihenfolge neben- und nacheinander ab. Zuerst bildet sich eine Waschhaut an Händen und Füßen aus, zuletzt lösen sich die Zehennägel ab. Eine Umwandlung in Fettwachs haben wir bei Rheinleichen schon nach zweieinhalb bis drei Monaten beobachtet. 3. Von den späten Leichenveränderungen haben wir insgesamt 10 Parameter systematisch überprüft und dabei deren Abhängigkeit von der Temperatur und Zeit festgestellt. Der Zeitraum schwankt zwischen 2 und 47 Tagen. 4. Mit Hilfe von Temperatur- Zeit-Diagrammen kann ermittelt werden, wielange eine Leiche mindestens im Wasser gelegen hat. Häufig ist auch eine Aussage über die maximale Wasserzeit möglich. 5. Folgende Bedingungen müssen erfüllt sein: a) Messung der Wassertemperatur am Fundort, b) Entkleiden der Leiche, c) kühle Lagerung der Wasserleiche an der Luft bei +4°C, d) Leichenschau oder Leichenöffnung am 2. oder 3. Tag nach der Bergung.
    Notes:
    Summary Putrefaction, autolysis and maceration of water corpses follow a regular sequence depending on the water temperature and the interval in the water, the socalled water period. We have determined the beginning of characteristic exterior and interior changes in 395 water corpses of adult persons with known immersion intervals and water temperatures at the place of discovery at the time of recovery. The corpses had been kept in a cooling-room at 4°C for 2 to 3 days until they were studied. Altogether 10 parameters have been considered and plotted (Fig. 1–3): intensive dyscoloration of the skin, gasformation, loosening of hair, loss of hair, putridity transsudate of more than 500 ml into the pleural cavitiesn, bloodlessness of the heart, softening and liquefaction of the brain, loosening of fingernails, loss of washer-woman's skin from the hands and loss of fingernails. Several parameters are synchronous (Fig. 1, 2). The studied intervals of exposure to water were from 2 to 47 days at water temperatures between 22 and 3°C. — By means of the three diagrams it can be found out how many days at the minimum a corpse had been submerged, if the water temperature at the place of discovery is known and storage in a cooling-room has taken place for 2 to 3 days. Also statements are possible about the maximal period of time. — Corpses found in the Rhine will develop washer-woman's skin on hands and feet after no less than 5 hours, even at summer temperatures, and adipocere after no less than 2.5 to 3 months. There is no difference between running and stagnant water in the chronological developments of the parameters investigated. Also the degree of water pollution does not affect the estimation of the time of death.

    Description / Table of Contents:
    Zusammenfassung Sehnen besitzen wie viele viscoelastische Körper die Eigenschaft der Relaxation. Die Relaxation ist um so stärker ausgeprägt, je höher folgende physikalische Größen sind: Dehnungsrate, Nennspannung bzw. Kraft, Temperatur und Dehydrationsgrad. Auch unter Berücksichtigung einer Vorspannung ist die Relaxation um so ausgeprägter, je größer der Spannungs- bzw. Krafthub ist. Im Kurz- und Langzeitrelaxationsversuch ist nach Ausgleich des Kraftabfalles die jeweilige erneute Relaxation flacher als die vorausgehende. In niedrigen Kraftbereichen entsteht nach wenigen Kraftausgleichen praktisch eine Gerade auf der Höhe des Ausgangsniveaus zu Beginn der Relaxation. Dehydration während des Relaxationsversuches bedingt eine deutliche Kraftzunahme. Die Klärung der Ursache der Relaxation bedarf einer molekularen Deutung. Sie wird auf reversible Sprengung der Nebenvalenzkräfte, insbesondere der bindungsenergiearmen Wasserstoffbrücken zurückgeführt.
    Notes:
    Summary Tendons have the property of relaxation like many viscoelastic bodies. The diagram of the relaxation is deeper when the following physical parameters are higher: strain-rate, nominal stress or force, temperature, and degree of dehydration. Under the application of a preload there is also the relaxation deeper, when the generating force is augmentet. In short and long time relaxation experiments there is after the compensation of the load decrease the next relaxation less deeper than the previous one. In the low domain of force there comes into existence a straight line at the niveau of the force at the beginning of the relaxation after few compensations. Dehydration during the relaxation causes an evident increase of the force. The interpretation of the relaxation has to take into account a discussion of molecular processes. The relaxation is explained as a time dependent process, which is caused by the disjunction of the noncovalent bounds, especially low energy hydrogen bounds.

    Notes:
    Summary Glutamine:fructose 6-phosphate amidotransferase (GFA) is rate-limiting for hexosamine biosynthesis, while a UDP-GlcNAc β-N-acetylglucosaminyltransferase (O-GlcNAc transferase) catalyses final O-linked attachment of GlcNAc to serine and threonine residues on intracellular proteins. Increased activity of the hexosamine pathway is a putative mediator of glucose-induced insulin resistance but the mechanisms are unclear. We determined whether O-GlcNAc transferase is found in insulin-sensitive tissues and compared its activity to that of GFA in rat tissues. We also determined whether non-insulin-dependent diabetes mellitus (NIDDM) or acute hyperinsulinaemia alters O-GlcNAc transferase activity in human skeletal muscle. O-GlcNAc transferase was measured using 3H-UDP-GlcNAc and a synthetic cationic peptide substrate containing serine and threonine residues, and GFA was determined by measuring a fluorescent derivative of GlcN6P by HPLC. O-GlcNAc transferase activities were 2–4 fold higher in skeletal muscles and the heart than in the liver, which had the lowest activity, while GFA activity was 14–36-fold higher in submandibular gland and 5–18 fold higher in the liver than in skeletal muscles or the heart. In patients with NIDDM (n = 11), basal O-GlcNAc transferase in skeletal muscle averaged 3.8 ± 0.3 nmol/mg · min, which was not different from that in normal subjects (3.3 ± 0.4 nmol/mg · min). A 180-min intravenous insulin infusion (40 mU/m2· min) did not change muscle O-GlcNAc transferase activity in either group. We conclude that O-GlcNAc transferase is widely distributed in insulin-sensitive tissues in the rat and is also found in human skeletal muscle. These findings suggest the possibility that O-linked glycosylation of intracellular proteins is involved in mediating glucose toxicity. O-GlcNAc transferase does not, however, appear to be regulated by either NIDDM or acute hyperinsulinaemia, suggesting that mass action effects determine the extent of O-linked glycosylation under hyperglycaemic conditions.

    Abstract Triton X-100 is applied to influenza vaccines at different stages of the manufacturing process to prevent aggregation and precipitation of biomolecules. Furthermore it is used to disintegrate the virus particles in split vaccine and to guarantee the homogeneity during production and utilisation. The final concentration of Triton X-100 has to be determined because the concentration changes in manufacturing process. The determination of the total amount of Triton X-100 as well as the separation of its ethylene oxide oligomers was possible with high-performance liquid chromatography (HPLC) and capillary electrophoresis (CE). In HPLC a change of the column and eluent was necessary, in CE different electrolytes were used for the various separation effects. The HPLC method for the analysis of total Triton was preferred for the quantification of Triton X-100 in influenza vaccine because of better linearity, reproducibility and detection sensitivity compared to CE. In the end products an average concentration of 0.117 mg/mL was found.

    Notes:
    Abstract For quality tests of ceramic Bi-Pb-Sr-Ca-Cu-O superconductor materials (precursors and final products) accurate stoichiometric determinations of the metallic major components are necessary. Three methods were developed during the last decade in our group. Their properties and the results obtained are compared. The first classical analytical procedure requires to much manpower. The second combined chemical-spectrometric procedure is a routine method today, but also unsuitable for rapid tests. A new fully spectrometric procedure was recently developed using a simultaneously working Echelle spectrometer with CID detector, autosampler and a special self-made data evaluation software. The basis of this method are multi-line measurements of each analyte element, a new method of spectral line selection for main component precision determinations, multi-component calibrations, and frequent external standardizations. For this method the sum of the confidence intervals of all element determinations was less than 1%, and no systematic error was detected.

    Abstract The large surface area of barks from many tree species enables the effective accumulation of pollutants. Therefore, the analysis of bark material will provide useful information about the degree of pollution of a certain region. The determination of main, minor, and trace elements (Al, Ca, Cd, Ce, Cr, Cu, Fe, Mn, P, Pb, S, Ti and Zn) in bark was performed with an Nd:YAG laser coupled to an ICP-MS system. Bark standards for the calibration by laser ablation ICP-MS were prepared from different bark layers which differ for some relevant elements in concentrations. Four digestion procedures for the decomposition of the standard pellets, the numbers of laser shots per sample and of samples per region necessary have been investigated. Representative results were obtained for 5 or more samples taken from different individuals of one species of a sampling area and the averaged element concentrations of 10 separately placed laser shots for each sample. Laser ablation ICP-MS was applied for the characterization of real bark samples from different regions with high and low pollution burden. It was shown that the method is well suited to characterize different degrees of environmental impact. Anthropogenic sources were responsible for the higher concentrations of most of the elements under investigation.

    Abstract  Nonionic surfactants are widely used in commercial formulations as complex mixtures requiring efficient and selective separation methods. Capillary electrophoretic separations were carried out in electrolytes containing high amounts of organic solvents and anionic surfactants based on the formation of association complexes between analytes and anionic surfactants without micelle formation. Octyl- and nonylphenol polyethoxylates were separated as their ethoxylate homologues. Influences of the electrophoretic conditions like electrolyte concentration and pH, type and content of anionic surfactant and organic solvents were investigated.

    Notes:
    Abstract Because of the widespread use, increased application of new formulations and immense impact on organisms and ecology surfactants are still in the focus of analytical chemistry. The development of methods with higher selectivity and lower detection limits is important to meet the requirements of greater responsibility for health of people and environment. Efficient separation methods, like HPLC, GC and CE, in combination with sensitive detection, like MS, are to be preferred over collective techniques which can suffer from interfering components. A review on trace analysis of ionic and neutral surfactants including sample preparation steps is presented, considering especially those methods which provide information about homologous and isomeric distribution of surfactant mixtures. Examples for the determination of linear alkylbenzene sulfonates in river water by HPLC and CE are discussed to show the capability of these methods for environmental analyses. As future trends increased applications of LC/MS (very high sensitivity) and also of CE (robustness and possibility for rapid method development) can be predicted.
