    Notes: Abstract. This is a report of clinical, CT and MRI findings in a patient with toxic spongiform leucoencephalopathy after heroin ingestion. The disease is observed in drug addicts who inhale pre-heated heroin. The clinical onset, which usually occurs some days or even longer after the last heroin consumption, is characterized by a cerebellar syndrome. The cerebellar hemispheres, the cerebellar and cerebral peduncles and the pyramidal tract may be affected. Spongiform demyelination is the morphological substrate of the lesions, which are not contrast enhancing, hypodense on CT and hyperintense on T2-weighted MRI. The frequently perfect symmetry of the affection of functional systems points to a toxic and/or metabolic pathophysiological mechanism.

    Description / Table of Contents: Abstract The diagnostic procedure in viral encephalitis is based on the synopsis of clinical signs and symptoms, serological data, CSF analysis and diagnostic imaging findings. This article summarizes the findings of those viral encephalitides most frequently encountered in Western Europe. MRI is more sensitive than CT for the detection of inflammatory brain lesions due to the higher contrast resolution. The pattern of parenchymal damage is highly specific in only some viral encephalitides (e. g., the frequently hemorrhagic lesions of structures of the limbic system in herpes simplex virus type I encephalitis; the symmetric and confluent lesions of the frontal white matter of progressive diffuse leukoencephalopathy in AIDS). In the majority of viral encephalitides MRI demonstrates the location and extension of parenchymal damage. The specific diagnosis in terms of the causative agent is based on serological studies.
    Notes: Zusammenfassung Die Diagnostik viraler Enzephalitiden basiert auf der synoptischen Auswertung klinischer, serologischer, liquoranalytischer und bildgebend erhobener Befunde. In der vorliegenden Arbeit werden die entsprechenden Befunde der häufigsten in Westeuropa viral verursachten Enzephalitiden dargestellt. Generell ist bei entzündlichen Läsionen des Hirnparenchyms die Kernspintomographie (MRT) aufgrund ihrer hohen Weichteilkontrastauflösung der Computertomographie (CT) hinsichtlich der Nachweissensitivität überlegen. Bei einigen viralen Enzephalitiden ist das kernspintomographisch erfassbare Schädigungsmuster hochspezifisch. Die gilt z. B. für die häufig hämorrhagischen Läsionen der Strukturen des limbischen Systems bei der Herpes-simplex-Virus-Typ-1-Enzephalitis und für die flächenhaft symmetrischen Marklagerläsionen bei der progressiven diffusen Leukenzephalopathie bei AIDS-Patienten. Bei der Mehrzahl der viralen Enzephalitiden weist die MRT zwar die Lokalisation und Ausdehnung der Parenchymschädigung nach, erlaubt jedoch keine sichere Zuordnung zu einem Erreger.

    Description / Table of Contents: Summary In 137 patients with different kinds of cancer and different cancer stage, cell-mediated immunity was investigated by DNCB (dinitrochlorobenzene) and tuberculin test. These two skin tests were performed before and after cytostatic drug combination therapy. For a collective of cancer patients we found a positive correlation between skin reactions and prognosis and a negative correlation between skin reactions and cancer stage. After cytostatic drug therapy skin reactions could be significantly stronger. This could be observed in 50% when one test was positive before chemotherapy and in only 20% when both tests were negative before chemotherapy. There existed a significant correlation between an increased reaction after cytostatic drug therapy and objective tumor regression. When skin reactions decreased, tumor progression was seen in all cases. Due to these observations we use skin reactions as a good parameter for therapy results. When delayed cutaneous hypersensitivity impairs 2–3 weeks after chemotherapy, we then change the cytostatic drug combination immediately. We cannot say at this moment, whether an improvement of cytostatic drug therapy can be reached in this way.
    Notes: Zusammenfassung Bei 137 Patienten mit unterschiedlichen soliden Karzinomen und verschiedenem Tumorstadium wurde die zelluläre Immunität durch Tuberkulin- und DNCB-(Dinitrochlorbenzol)-Test untersucht. Die Tests wurden vor und nach zytostatischer Stoßtherapie durchgeführt. Insgesamt fanden wir eine positive Korrelation zwischen Hauttests und Prognose und eine negative Korrelation zwischen Hauttests und Tumorstadium. Wenn mindestens ein Test vor Chemotherapie positiv war, konnten wir in ca. 50% eine Verbesserung der zellulären Immunität registrieren, dagegen nur in 20%, wenn beide Tests vor zytostatischer Therapie negativ waren. Ein signifikanter Zusammenhang zwischen verbesserter Reaktion auf Tuberkulin und/oder DNCB nach zytostatischer Therapie und objektiver Tumorrückbildung wurde beobachtet. Wenn beide Reaktionen schwächer wurden, folgteimmer eine Tumorprogression. Aufgrund dieser Beobachtungen verwenden wir die Hauttests als wertvollen Parameter für den Therapieerfolg. Wir wechseln daher sofort die Zytostatikakombination, wenn 2–3 Wochen nach Chemotherapie die Hautreaktionen schwächer werden. Ob hierdurch eine Verbesserung der Zytostatikatherapie möglich ist, kann derzeit noch nicht sicher gesagt werden.

    Description / Table of Contents: Abstract The hematogenous spread of bacteria, fungi and protozoa may also reach the brain vessels, which happens mostly through septic emboli. From such an embolus a metastatic focal encephalitis and later a septic-embolic brain abscess may arise. The most frequently underlying infections that may cause septic emboli are bacterial endocarditis as well as bacterial infections of artificial heart valve prostheses. Congenital heart malformations with a right-to-left shunt also play here a certain role. Basically, however, all septic conditions and bacteriemias may cause septic-embolic brain abscesses. They occur frequently as multiple lesions. MRI is superior to CT in depicting the different stages of evolution from focal encephalitis, through the hardly encapsulated early abscess, to the formation of a membrane and later a dense fibrous capsule. The medical treatment of a brain abscess requires properly performed CT or MRI follow-up examinations in order to realize early enough a possible growing of such a lesion.
    Notes: Zusammenfassung Die hämatogene Ausbreitung von Bakterien, Pilzen oder Protozoen bis in die Hirngefäße erfolgt meist durch eine septische Embolie. Es entstehen eine metastatische Herdenzephalitis und im weiteren Verlauf daraus ein septisch-embolischer Hirnabszess. Die häufigste Grunderkrankung die zu septischen Embolien führt ist die bakterielle Endokarditis sowie die bakterielle Infektion von Herzklappenprothesen. Eine besondere Bedeutung kommt hier den angeborenen kardialen Fehlbildungen mit Rechts-Links-Shunt zu. Grundsätzlich können jedoch alle Bakteriämien zu septisch-embolischen Hirnabszessen führen. Septisch-embolische Hirnabszesse treten aufgrund ihres Entstehungsmechanismus häufig multipel auf. Die CT und besser noch die MRT erlauben die Darstellung aller Entwicklungsstadien von der Herdenzephalitis über den kaum abgegrenzten Abszess, die Membranbildung bis zur Entstehung einer dicken, die eitergefüllte Höhle allseits umgebenden Abszesskapsel. Die medikamentöse Therapie von Hirnabszessen erfordert Verlaufsuntersuchungen, um einer eventuellen Größenzunahme der Läsion(en) frühzeitig durch Umstellung der antibiotischen Medikation oder durch operative Abszessentfernung zu begegnen.

    Notes: Abstract  We describe the use of wheat microsatellites for the discrimination of Aegilops markgrafii chromosomes. Twenty out of eighty eight wheat microsatellites (WMS) tested were able to distinguish Triticum aestivum-Ae. markgrafii addition lines. Six, three, three, one and six of 18 WMS can be used as markers for single Ae. markgrafii chromosomes B, C, D, F and G, respectively. Addition line A is not available but additional bands, appearing only in Ae. markgrafii and the T. aestivum-Ae. markgrafii amphiploid and not in any of the available addition lines, indicate that three WMS detect markers for Ae. markgrafii chromosomes A. Addition line E could not be detected by any of the WMS markers applied, although the 20 WMS represented all the homologous groups of wheat. All three WMS located on the short arm of group-2 chromosomes were located on Ae. markgrafii chromosome B; three of four WMS, located on the long arm of wheat group-2 chromosomes, were specific to Ae. markgrafii chromosome G and three of four WMS, specific to group-5 chromosomes, were markers for Ae. markgrafii chromosome C, indicating the homoeology of these wheat chromosome arms with the respective Ae. markgrafii chromosomes.

    Notes: Abstract  Aegilops markgrafii contains resistance genes to powdery mildew, leaf rust and stripe rust, and also has high crude protein and lysine contents, which can be useful for wheat improvement. These important traits are localized on different chromosomes. Disomic Triticum aestivum-Ae. markgrafii addition lines and euploid introgression lines showing leaf-rust and powdery mildew resistance were screened with RAPDs to detect chromosome-specific markers which can accelerate the breeding process. RAPD markers for all six available disomic addition lines were obtained. The additional chromosomes B, C, D, E, F and G were identified by three, three, three, two, one and seven primers, respectively. All three chromosome-B-specific RAPD markers demonstrated the presence of alien chromatin in the leaf-rust-resistant 42-chromosome introgression lines as well as in the segregating progeny. The three chromosome-C-identifying primers also demonstrated the presence of that chromosome in powdery mildew-resistant euploid introgression lines. The substitution lines (5A)5C and (5D)5C with different genetic backgrounds for both parents, in comparison to the lines mentioned above, showed the chromosome C-specific band with only two of the three primers. The chromosome F-specific primer and a primer evident on all the Ae. markgrafii chromosomes analysed did not generate the expected fragments on the chromosome Fdel addition line, indicating that the markers are located on the deleted part of chromosome F.

    Notes: Summary We established a chromosome specific DNA library of the Aegilops markgrafii chromosome B. Eight microdissected chromosomes B obtained from a monosomic T. aestivum-Aegilops markgrafii addition line were PCR-amplified and the DNA was cloned in Escherichia coli DH5α. Clones were characterized by dot blot hybridization with total Ae. markgrafii DNA. 62% of clones represented repetitive sequences and 38% low or single copy sequences. The estimated length of excised inserts varied between less than 200 bp and more than 500 bp. The average size of inserts was 310 bp.
