    Notes: Abstract The adhesion is a fundamental property of hard coatings in view of tribological-mechanical demands. The quantification of adhesion between coating and substrate is with respect to practice not easy to handle, even so the scratch test is the best established and well discussed test method. The present study analyzes the test procedure and proposes a possible evaluation method and interpretation of the results to reach sufficient reproducibility due to a better standardization.

    Notes: Summary The cutaneous infiltrate in mycosis fungoides (MF) is predominantly composed of T4-positive T-cells. Attempts to distinguish the early stages of this condition from benign inflammatory infiltrates using anti-T3, T4 and other T-cell-associated antibodies have hitherto been unsucessful. Recently a monoclonal antibody BE 2 has been described as selectively reacting against leukemic cells in patients with cutaneous T-cell lymphoma. To investigate whether the BE 2 antigen is differentially expressed in different stages of MF and benign dermatoses, thus facilitating diagnosis, especially of early MF, the reactivity of monoclonal antibody BE 2 against cutaneous infiltrates from such conditions was assessed. In the early stages of MF only a small number of reactive cells was present. In benign inflammatory infiltrates, especially in those that clinically and histologically were hardly distinguishable from early MF, BE 2 reactivity was essentially the same as in eczematous-stage MF. Lesions from plaque and tumor stage MF contained large numbers of BE 2-reactive cells. Our results indicate that expression of BE 2 is associated with the stage of a given MF lesion and is essentially identical in early MF and eczematous lesions with a similar histopathological appearance.

    Notes: Abstract. The timing of replication of mouse ribosomal RNA (rRNA) genes was determined in cultured cells by using 5-bromodeoxyuridine labeling of DNA coupled with synchronization. Two subclasses of rRNA genes were characterized that differ in their temporal order of replication during S-phase. Approximately half of the rDNA repeat units replicated primarily during the first half of S-phase and the other 50% preferentially in the second half. This difference in replication timing was consistently observed for the approximately 400 rDNA repeat units of NIH3T3 fibroblasts, but not for plasmid DNA containing fragments of rRNA genes that had been stably transfected into the genome of these cells. The rDNA fragments inserted into these transfection vectors contained the recently mapped origin of bidirectional replication with or without amplification-promoting sequences, or none of the above. Since the plasmid DNA that was integrated into the host cell genome replicated randomly during S-phase we conclude that the integrated plasmid DNA is either replicated from a chromosomal origin in the neighborhood of its integration site or that inserts are replicated from their own origins and the timing of replication is determined by flanking sequences.

    Notes: Abstract We prospectively compared the diagnostic value of C-reactive protein (CRP) and white blood cell counts for detection of neonatal septicaemia. Sensitivity and specifity in receiver operating characteristics, and positive and negative predictive value of CRP and white blood cell count were compared in 195 critically ill preterm and term newborns clinically suspected of infection. Blood cultures were positive in 33 cases. During the first 3 days after birth CRP elevation (sensitivity 75%, specifity 86%), leukopenia (67%/ 90%), neutropenia (78%/80%) and immature to total neutrophil count (I/T) ratio (78%/73%) were good diagnostic parameters, as opposed to band forms with absolute count (84%/66%) or percentage (79%/ 71%), thrombocytopenia (65%/57%) and toxic granulations (44%/94%). Beyond 3 days of age elevated CRP (88%/87%) was the best parameter. Increased total (84%/66%) or percentage band count (79%/71%) were also useful. Leukocytosis (74%/ 56%), increased neutrophils (67%/ 65%), I/T ratio (79%/47%), thrombocytopenia (65%/57%) and toxic granulations had a low specifity. The positive predictive value of CRP was 32% before and 37% after 3 days of age, that of leukopenia was 37% in the first 3 days.

    Description / Table of Contents: Summary A potential impact of tricyclic antidepressants on oral anticoagulation is controversial. Phenprocoumon – the most commonly used anticoagulant in Germany – is rarely considered in clinical trials. In the present study, a potential drug-drug interaction between phenprocoumon and tricyclics, causing an alteration in prothrombinemic effects, has been investigated. In eleven patients simultaneously receiving tricyclic antidepressants and phenprocoumon the course of Quick values and the phenprocoumon dosages were compared to a control group of eleven phenprocoumon treated patients not receiving tricyclics. Quick value deviations from the individually required therapeutic ranges 〉25%, as well as frequent changes in the phenprocoumon dosages were indicators of an inconstant oral anticoagulation and a possible interaction. The results showed unstable prothrombinemic effects throughout tricyclic antidepressant therapy. The average Quick value deviation amounted to 68.7% in the patients group and to 13.1% in the control group. Additionally, there was an average change in phenprocoumon dosage of 0.6 in the patients group and of 0.2 in the control group. Further controlled studies are certainly warranted to specifically answer the question of a clinically relevant drug-drug interaction.
    Notes: Zusammenfassung Eine mögliche Beeinflussung der Antikoagulanzientherapie durch trizyklische Antidepressiva wird bislang unterschiedlich bewertet. Vor allem das in Deutschland therapeutisch eingesetzte Antikoagulanz Phenprocoumon bleibt bei Untersuchungen nahezu unberücksichtigt. Die vorliegende retrospektive Studie wurde unter der Fragestellung einer potentiellen Arzneimittelinteraktion zwischen Phenprocoumon und Trizyklika durchgeführt. Bei 11 gleichzeitig mit Trizyklika und Phenprocoumon behandelten Patienten und 11 antikoagulierten Kontrollen ohne antidepressive Therapie erfolgte eine Gegenüberstellung von Quickwertverlauf und Phenprocoumondosis während und außerhalb trizyklischer Therapie. Quickwertabweichungen vom therapeutischen Bereich 〉25% und häufige Phenprocoumon-Dosiswechsel galten als Zeichen einer instabilen Antikoagulation und einer zugrundeliegenden Interaktion. Sowohl im intraindividuellen Patientenvergleich wie auch in der Gegenüberstellung von Patienten- und Kontrollkollektiv wurde eine instabile Phenprocoumonwirkung unter Trizyklikatherapie gezeigt. Die mittlere Quickwertabweichung [mQWA] betrug im Patientenkollektiv 68,7%, im Kontrollkollektiv 13,1%. Für das Patientenkollektiv wurde eine mittlere Dosiswechselzahl [mDWZ] von 0,6 errechnet. Im Kontrollkollektiv lag die mDWZ bei 0,2. Inwiefern unsere Beobachtungen als Indikator einer potentiellen Arzneimittelinteraktion gelten können, ist in diesem Rahmen nicht abschließend zu beurteilen. Zur endgültigen Abklärung der Fragestellung erscheint die Durchführung prospektiver Studien angezeigt.

    Notes: Thin-layer (uni-dimensional and bi-dimensional) chromatography studies were performed on 52 beige stockings and pantyhose from different countries. They demonstrated the presence of Disperse Yellow 3 in 51 and Disperse Orange 3 in 15 stockings. In the absence of isolation and spectroscopic identification of the dyes, these results are strong clues to their presence.
