    Notes: Abstract The ospC gene coding for the outer surface protein OspC and the fla gene coding for the flagellin have been investigated in three different Borrelia burgdorferi sensu lato strains. These strains (the North American strain B31 and the European strains PKo and PBi) derive from various biological sources (lxodes dammini, human skin and human CSF) and belong to three different B. burgdorferi OspA serotypes and genospecies (OspA serotype 1, B. burgdorferi sensu stricto; OspA serotype 2, group VS461 and OspA serotype 4, B. garinii, respectively). The ospC and fla genes of the respective strains have been amplified by polymerase chain reaction, cloned in pUC8 and sequenced. The fla as well as the ospC genes were different among the three strains investigated. In general the fla genes are more conserved than the ospC genes. The fla genes have the same length of 1008 nucleotides coding for proteins of 336 amino acids, whereas the ospC genes differ in length. The ospC genes of strains B31, PKo and PBi have 630, 636 and 621 nucleotides encoding proteins of 210, 212 and 207 amino acids, respecctively. The ospC genes exhibit sequence identities between 70% and 74% among each other, sequence identities of the fla genes are in the range 96–97%. The ospC genes could be expressed in Escherichia coli to obtain proteins with and without leader peptides. The expression of the fla gene and an internal gene fragment resulted in the complete flagellin protein and a truncated protein (amino acids 129–251). The different ospC and fla gene products were immunoreactive with monoclonal antibodies and human sera and, thus, enlarge the spectrum of recombinant antigens to improve antibody detection in patients with Lyme borreliosis.

    Notes: Summary The fluid composition of five epididymal spermatocoeles, one epididymal cyst and a hydrocoele was examined. The fluid obtained from the spermatocoeles was a dilute suspension of mainly immotile spermatozoa. The sperm-free fluid contained less protein, phosphate, glucose, triglyceride and cholesterol than serum but more testosterone and chloride than peripheral blood. It contained no epididymal secretion products. Proteins in the fluid differed from those in serum. From the fluid composition these cysts appeared to be continuous with the rete testis, either dilatations of efferent ducts or Haller's superior aberrant duct (vas aberrans of the rete testis). Fluid from an epididymal cyst containing no spermatozoa was mainly of similar composition. In contrast, hydrocoele fluid resembles blood serum.

    Description / Table of Contents: Abstract Methicillin resistant Staphylococcus aureus-strains, isolated from 1994 to 1997 from patients of the traumatic surgery hospital Tübingen, were compared using lysotyping and pulsed-field gel electrophoresis. Both typing methods detected two clones causing an outbreak 1994 in 6 patients and a third endemic clone of MRSA, which was isolated from 5 patients (1995), 4 patients (1996), and 6 patients (1997). Additionally other MRSA-types were found in 6 cases of which transmissions occurred in up to three patients. An epidemiological connection to MRSA isolated from patients of the university hospital of Tübingen was made. Possible consequences for patient management and antibiotic strategies in MRSA-infections were discussed.
    Notes: Zusammenfassung Methicillin-resistente Staphylococcus-aureus-Isolate (MRSA) der Berufsgenossenschaftlichen Unfallklinik Tübingen (BGU) aus den Jahren 1994–1997 wurden mit Hilfe der Lysotypie und der Pulsfeldgelelektrophorese verglichen. Beide Typisierungsmethoden zeigten, daß 1994 ein Ausbruch von 6 Infektionen auf 2 verschiedene Klone zurückzuführen war. Sie wiesen weiterhin das Auftreten eines in der BGU endemischen Klones bei 5 (1995), 4 (1996) und 6 (1997) Patienten nach. Übertragungen von anderen MRSA-Typen fanden in 6 Fällen statt, bei denen die MRSA auf bis zu 3 Patienten transferiert wurden. Ein epidemiologischer Zusammenhang zu MRSA-Isolaten von Patienten des örtlichen Universitätsklinkums wurde hergestellt; mögliche Konsequenzen für das Patientenmanagement und die Chemotherapie von MRSA-Infektionen wurden diskutiert.

    Notes: Abstract: Production cross-sections of charged pions, kaons and antikaons have been measured in C+C and C+Au collisions at beam energies of 1.0 and 1.8 AGeV for different polar emission angles. The kaon and antikaon energy spectra can be described by Boltzmann distributions whereas the pion spectra exhibit an additional enhancement at low energies. The pion multiplicity per participating nucleon M(π+)/〈A part〉 is a factor of about 3 smaller in C+Au than in C+C collisions at 1.0 AGeV whereas it differs only little for the C and the Au target at a beam energy of 1.8 AGeV. The K+ multiplicities per participating nucleon M(K+)/ 〈A part〉 are independent of the target size at 1 AGeV and at 1.8 AGeV. The K- multiplicity per participating nucleon M(K-)/ 〈A part〉 is reduced by a factor of about 2 in C+Au as compared to C+C collisions at 1.8 AGeV. This effect might be caused by the absorption of antikaons in the heavy target nucleus. Transport model calculations underestimate the K-/K+ ratio for C+C collisions at 1.8 AGeV by a factor of about 4 if in-medium modifications of K-mesons are neglected.

    Description / Table of Contents: Abstract Seeds of Betula platyphylla var. japonica (provenances from Hokkaido and Hondo, Japan) were sown in 1959. The seedlings were planted one year later in Großhansdorf/Schleswig-Holstein. At the age of 37 years, 20 trees were felled and the butt and top logs used for the determination of some wood properties e.g. density, swelling and shrinkage, mechanical properties. At both height levels, mean air-dry (11–12% m c) density is an uniform 0,60 g/cm3. Along the density increases from pith to bark. The wood of the investigated trees has lower mechanical properties, but more favourable swelling and shrinkage values compared with European birches.
    Notes: Zusammenfassung Saatgutproben von Betula platyphylla var. japonica (Herkünfte Hokkaido und Hondo, Japan) wurden im Jahre 1959 ausgesät. Die Jungpflanzen wurden ein Jahr später in Großhansdorf/Schleswig-Holstein angepflanzt. Im Alter von 37 Jahren wurden bei einer Durchforstung 20 Bäume entnommen, von denen ein unterer und ein oberer Stammabschnitt zur Untersuchung der Holzeigenschaften dienten. Für beide Stammhöhen ergab sich eine einheitliche mittlere Rohdichte von 0,60 g/cm3 im normalklimatisierten Zustand. Dagegen entspricht die Rohdichtezunahme vom Mark zum Kambium der bei anderen Birken üblichen Verteilung. Das Holz der untersuchten Bäume besitzt geringere mechanische Eigenschaften, aber günstigere Quell- und Schwindmaße als das Holz europäischer Birken.
