    Changes in Biogenic Amine Content of Tokaj Grapes, Wines, and Aszu-wines (2000)

    Notes: : Biogenic amines in grapes, aszu-grapes, wines, and aszu-wines of the Tokaj region of Hungary were separated, identified, and quantified by HPLC. The biogenic amine content of the Tokaj wines was well below the suggested limits for any of the biogenic amines. Histamine contents were especially low in all the samples investigated. The composition and concentration of the biogenic amines (polyamines) in the grape berries were altered remarkably by the Botrytis cinerea, and this resulted in a great change of the amine concentration in the aszu-wines compared to the wines. The composition and concentration of biogenic amines might provide useful information on the vintage and can support the authentication of the Tokaj aszu-wines.

    Early detection of metastasis by alterations in the cellular immune system in the murine liver and blood (1996)

    Notes: Abstract We investigated the reaction of the cellular immune system of liver and blood in the C57BL/6 mouse to a metastasizing Lewis lung carcinoma. The cellular immune system of the liver consists of mature and immature macrophages, B-cells, T-cells including their subpopulations, and natural killer cells, and their percentage frequencies differ significantly from those in the corresponding mononuclear blood cell (MBC) compartment. This suggests that the hepatic immune cells represent a system with autonomous function showing a typical homing of its members. Imminent metastasis to the liver is signalled by impressive alterations in the percentage frequencies of nonparenchymal liver cells (NPLC). There are a dramatic loss of mature macrophages, an increase in immature macrophages, a reduction of T-helper cells leading to a low CD4/CD8 ratio, and an increase in natural killer cells. In the blood, the corresponding precursor cells show comparable changes with a delay of at least 2 days. Early metastasis is accompanied by a significant increase in mononuclear NPLC producing tumour necrosis factor α. The alterations in percentage frequencies of the NPLC during tumour metastasis differ markedly from the changes in these cells in the liver during endotoxinaemia.

    Light microscopic triple-colored immunohistochemical staining on the same vibratome section using the avidin-biotin-peroxidase complex technique (1988)

    Notes: Summary The sequential application of the avidin-biotinperoxidase complex technique was used to localize multiple tissue antigens on a single free floating section of rat brain. sequential visualization of individual antigens was achieved by the silver-gold-intensified diaminobenzidine (DAB) in the first step, nickel-intensified DAB in the second step, and the DAB alone in the third step of the immunostain procedure. For the demonstration of this method, tyrosine hydroxylase (TH), corticotropin-releasing factor (CRF), and vasopressin (VAS) antisera were used. Sections from the hypothalamic paraventricular nucleus (PVN) of rats pretreated with colchicine were stained. Black TH containing cell bodies were clearly distinguished from blue stained CRF cells and from yellow stained VAS-containing cell bodies in the PVN on the 25–30 μm thick vibratome sections. The sequential immunostaining procedure presented here results in superior staining of multiple antigens as compared to that achieved by the sequential application of the peroxidase-antiperoxidase (PAP) technique.

    Mean corpuscular volume is not a reliable marker of red cell age in case of anisocytosis (1998)

    Notes: Abstract  The present study was designed to determine the effect of anisocytosis on the association of MCV values with HbA1c and reticulocyte counts as markers of red cell age. Normo-, micro- and macrocytic samples, fractionated by counterflow centrifugal elutriation were studied. The previously described correlation between MCV and HbA1c was only observed in normal samples and in the middle fractions of samples with anisocytosis. At both extremes of the elutriation profile, curves for HbA1c content and reticulocyte count levelled out. Furthermore, in fractions containing the largest red cells of the microcytic series and the smallest red cells of normo- and macrocytic samples, reticulocyte count decreased while HbA1c content increased with increasing MCV. From these data it is concluded that MCV is not an absolute determinant of red cell age in case of anisocytosis.

    Course of cerebral lesions in a patient with periarteritis nodosa studied by magnetic resonance imaging (1989)

    Notes: Summary The course is reported of a patient with periarteritis nodosa who initially presented with neurological symptoms. Multiple cerebral lesions were documented by the first magnetic resonance imaging (MRI) investigation. The majority of these had disappeared completely in the follow-up MRI studies. In contrast to neurological improvement the patient eventually died due to multiorgan failure. Postmortem histological examination revealed no pathological findings in the brain except one single necrotic area already known from MRI. Remissions of histological and angiographic alterations in periarteritis nodosa have been described as “local healing” leading to fibrosis and scarring. Our findings suggest that restitutio ad integrum may occur, at least in cerebral lesions.

    Operation characteristics of the Au-II 690-nm laser transition in a segmented hollow-cathode discharge (2000)

    Notes: Abstract. Single-mode operation at the Au-II 690-nm transition was obtained in a segmented hollow-cathode discharge laser without the use of any additional frequency-selective device. The pressure of the helium buffer gas, which is responsible for the significant homogeneous broadening of the laser line, was varied between 10 and 20 mbar. The discharge was excited with rectangular current pulses (up to 3 A) six times exceeding the threshold value. The time dependence of the laser output during the 1-ms-long discharge pulses is explained on the basis of the temperature and pressure changes in the tube. The highest small-signal gain at optimal discharge conditions was 11%m−1.

    Investigation on the possibility of cold nuclear fusion in Fe-Zr amorphous alloy (1989)

    Notes: Abstract Neutron, γ and Mössbauer spectroscopy were used to study the possibility of cold nuclear fusion in Fe90Zr10 amorphous ribbon having high hydrogen absorbing ability. No significant changes in the neutron and in the γ spectra were found at deuterization performed electrochemically at different cathodic potentials. The observed differences between the Mössbauer spectra of samples deuterized in air and in nitrogen atmosphere can be explained by decrease of deuterium uptake as well as by a small heat effect due to reaction of hydrogen with oxygen dissolved in water in the case of electrolysis carried out in air.
