    Notes: Abstract The grasshopper Oedaleonotus enigma possesses a neo-XY sex system and the rest of the chromosome complement is highly polymorphic, suggesting recent chromosomal evolution. It contains a fusion between two telocentrics, a centric shift and an extra heterochromatic segment, all of which are polymorphic, and in addition it has B-chromosomes. The fusion polymorphism has a preponderance of heterokaryotypes, and despite frequent inbreeding the other two polymorphisms have binomial frequencies of heterokaryotypes. Male individuals with two neo-X chromosomes and no neo-Y (at least in the germ line) are discussed.

    Description / Table of Contents: Zusammenfassung Bei 18 von 39E. corrodens-Stämmen konnte mit einem einfachen Verfahren eine „twitching motility“ nachgewiesen werden. Alle Stämme, bei denen dieser Beweglichkeitstyp gefunden wurde und einige Stämme, bei denen der Nachweis nicht gelang, bildeten auf festen Nährböden Schwärmsäume aus.
    Notes: Abstract In 18 out of 39 strains ofE. corrodens twitching motility was observed. Spreading colonies were associated with this kind of motility.

    Notes: Abstract 396 strains ofV. parahaemolyticus, 345 originating from Togo and 51 from Japan, were submitted to the study of butandiol dehydrogenase (BDH). It was found that 52.3% of the strains were BDH-positive and 44.2% BDH-negative. An intermediate group characterized by weak reactions amounted to 3.5% of the strains. The distribution of this enzyme parallels to a certain degree the results of serotyping. Positive reactions have been found in all or moat strains belonging to serotypes 03K29, 04K8, 04K12, 04K55, 05K15 and 012K19, whereas strains of serotypes 03K5 and 04K10 gave negative reactions. In serotype 05K17 both properties were found in nearly equal proportions. The test of BDH, which can supplement serotyping in characterizing strains ofV. parahaemolyticus, can be applied as an aid to epidemiological studies.

    Description / Table of Contents: Abstract Magnetic resonance (MR) imaging is one of the best methods in diagnosis of multiple sclerosis, particularly in disclosure of active demyelinating lesions. Aim of this study was to compare diffusion weighted imaging and contrast enhancement in the detection of active lesions. A MR study with a contrast enhanced T1-weighted pulse sequence with magnetization transfer presaturation and a diffusion weighted echoplanar pulse sequence (b=1000 s/mm2) was performed in 17 patients (11 women, 6 men) with multiple sclerosis. 29 of 239 lesions showed an increased signal intensity in diffusion weighted imaging, 24 lesions a contrast enhancement, but only 16 lesions were visible in both pulse sequences. In patients with short clinical symptomatology significant more lesions could be detected with diffusion-weighted pulse sequence in comparison to patients with long standing symptomatology showing more lesions with contrast enhancement. Hence it is likely, that both pulse sequences detect different histopathologic changes. The early detection of demyelinating lesions in diffusion weighted imaging is attributed to the extracellular edema, however the contrast enhancement is caused by a blood brain barrier abnormality. It can be expected that diffusion weighted imaging will have a high impact on imaging of multiple sclerosis not only in therapeutic trials, but also in clinical routine.
    Notes: Zusammenfassung Die Magnetresonanztomograpie ist eine der wichtigsten Untersuchungsmethoden in der Diagnostik der Encephalitis disseminata, insbesondere im Nachweis aktiver Entmarkungsherde. Ziel der Untersuchung war es, diffusionsgewichtete und kontrastverstärkte Untersuchungen bezüglich der Erkennung aktiver Läsionen zu vergleichen. Bei 17 Patienten (11 Frauen, 6 Männer) mit bekannter Encephalitis disseminata wurden sowohl eine kontrastverstärkte T1-gewichtete Sequenz mit Magnetization-Transfer-Sättigung als auch eine diffusionsgewichtete Echoplanar-Sequenz (b=1000 s/mm2) durchgeführt. 29 der 239 Läsionen zeigten eine Signalsteigerung in der diffusionsgewichteten Sequenz, 24 eine Kontrastmittelaufnahme, jedoch waren nur 16 Läsionen in beiden Techniken nachweisbar. Bei Patienten mit kurzzeitig bestehender Symptomatik zeigten sich signifikant mehr Entmarkungsherde mit Signalsteigerung in der Diffusionswichtung im Vergleich zu Patienten mit länger bestehender neurologischer Symptomatik, die mehr kontrastmittelaffine Läsionen aufwiesen. Dies lässt darauf schließen, dass mit beiden Verfahren unterschiedliche histopathologische Veränderungen beobachtet werden. Das sehr frühe Auftreten der Diffusionsänderung in den Entmarkungsherden wird auf das Ödem zurückgeführt, während die Kontrastmittelaufnahme durch eine Blut-Hirnschranken-Störung verursacht wird. Es ist zu erwarten, dass die diffusionsgewichtete Magnetresonanztomographie einen hohen Stellenwert in der Bildgebung der Encephalitis disseminata nicht nur in Therapiestudien, sondern auch in der klinischen Routinediagnostik erlangen wird.
