    Notes: Abstract Polyglucosan bodies (PGBs) in the brain of a 12-year-old Holstein cow exhibiting no signs of neurological abormality were examined by light and electron microscopy and immunohistochemistry. PGBs were disseminated throughout the brain, especially in the pallidum, thalamus and cerebellum. Cow PGBs were found in the neuronal perikaryon and in the neuropil. These were round, slightly to severely basophilic, and were strongly positive for the periodic acid-Schiff reaction. The cow PGBs were immunoreactive for monoclonal antibodies raised against human polyglucosan. Electron microscopic analysis revealed that they were composed of branching filaments, glycogen granules and electrondense meterial. These findings indicate that cow PGBs closely resemble human or canine PGBs in Lafora's disease and PGBs found in aged animals that have been reported previously.

    Notes: Abstract Eight patients with a juvenile type of distal and segmental muscular atrophy of the upper extremities (DSMA), a type of cervical flexion myelophathy, were evaluated using MR imaging. In the neutral position there was no spinal cord compression, but in flexion the spinal cord was displaced anteriorly and was compressed by the posterior surfaces or margins of the vertebrae and/or any herniated disks in all cases. In flexion, compression of the cord was exaggerated in seven patients by the anterior displacement of the posterior margin of the thecal sac, which was accompanied by dilated posterior internal vertebral veins. In patients suspected of having DSMA, MR images made in flexion are regarded essential for verifying the diagnosis.

    Sensitivity distribution asymmetries in magnetoresistive heads with domain control films (abstract) : 38th Annual Conference on Magnetism and Magnetic Materials (1994)

    Notes: Suppression of the sidetrack reading behavior is important in achieving⋅high track-density recording with a magnetoresistive head. In the present work, we investigate the sensitivity distribution profiles of MR heads through experimentation using a microtrack technique1 and computer simulation. Shielded, soft, adjacent-layer-biased MR heads with 3∼6−μm-wide tracks are used. The ends of the MR elements are coupled to antiferromagnetic or hard ferromagnetic films for domain control. In the simulation based on the Landau–Lifshitz–Gilbert equation,2 the magnetization configurations in the MR elements of the domain stabilizing films are calculated to analyze the sensitivity distribution. The measured sensitivity profiles in all cases have asymmetries that are reversed when the sensing current direction or the magnetization direction of the MR element is reversed. These results agree with the simulation. The asymmetries of sensitivity profiles are explained by the magnetic poles at the domain control film edges and at the transverse edges of the element which generate a diagonal demagnetizing field distribution in the sensing region.

    Operational characteristics of the impregnated-electrode-type liquid-metal ion source with multiple tip and reservoirs : Proceedings of 5th international conference on ion sources (1994)

    Notes: A new type of impregnated-electrode-type liquid-metal ion source, which eliminated the heating problem in the previous source, has been developed with multiple tip and reservoirs (TAR's). In the present ion source, the TAR's are connected electrically in series by modifying the TAR holding system. In order to achieve uniform heating of the TAR's, the materials of the knife-edged electrodes, which introduce the heating current to the TAR's, were examined. Tantalum electrodes exhibited better results as compared with the conventional Mo electrodes. Both of the two TAR's could be heated up to 700 °C with a heating power of 200 W. The maximum indium ion current of 9.1 mA was obtained from the four-TAR source with 40 emission points. Since the present ion current was limited by the current capacity of the extraction power supply, an ion current of more than 10 mA will be expected with a larger power supply. The results indicated that an ion current approximately proportional to the number of the emission points was obtained. This kind of ion source could be used as a general ion source in materials science.

    Histological evaluation of bone—cement interface affected by polyethylene particles in rabbit knee (1994)
    Springer
    Journal of materials science 5 (1994), S. 610-612

    Notes: To investigate the biological process of aseptic component loosening caused by polyethylene wear debris, nine rabbits were implanted with acrylic cement into the non-weight-bearing intercondylar notch of distal femur. Six animals were administrated the particles of polyethylene into the knee joint repeatedly for 12 weeks. At the bone-cement interface, thin connective tissue was observed, while bone sometimes existed directly next to the acrylic cement. The percentage of the length of interposed fibrous tissue against the total length of bone-cement interface was measured. The percentage was 15.8±10.3 in the polyethylene-injected group and 8.3±7.7 in the control group (no significance). While not significant, the amount was greater in the polyethylene-injected group. Thus it is proposed that the polyethylene particles played a role in bone resorption and fibrous tissue formation at the bone—cement interface. In some specimens, macrophages and foreign body giant cells that surrounded the particles near the articular surface were seen to cause resorption of bone. It is supposed that this phenomenon is similar to the focal osteolysis that is sometimes observed around a prosthetic component.

    Increase of labeling indices in gastrointestinal mucosae of mice and rats by compounds of the okadaic acid type (1994)

    Notes: Abstract Effects of compounds of the okadaic acid type (okadaic acid, dinophysistoxin-1, calyculin A and tautomycin) on proliferation by digestive-tract epithelial cells were investigated in mice and rats. In mice, a single oral administration of these agents caused significant enhancement of BrdU labeling indices in a dose/response manner. Exceptions showing no response were limited to the pyloric mucosa for okadaic acid, the pyloric and fundic mucosa for calyculin A and the pyloric mucosa for tautomycin. Sequential analysis of labeling indices after a single oral administration of dinophysistoxin-1 revealed two peaks of cell proliferation at 18 h and 36 h in the esophagus, ileum and colon. The labeling indices of the forestomach, fundus, pylorus and jejunum, on the other hand, continuously increased from 6 h after the administration. Elevated proliferation was also observed in the skin after 30 h or after, but no effects on the liver or kidney were evident. A single oral administration of the okadaic acid type of compounds also dose-dependently enhanced cell proliferation of the rat digestive tract. These results strongly suggest that the okadaic acid class of compounds may exert promoting potential for the gastrointestinal mucosa when administered orally.

    Notes: Summary Recombinant human granulocyte colonystimulating factor (rhG-CSF) and erythropoietin (rhE-PO) were used to treat ten patients with myelodysplastic syndromes (MDS). None of the patients showed a favorable response in erythrocyte and platelet counts following 10 weeks' treatment, although favorable responses in neutrophil counts were observed in eight of ten patients (80.0%) and in seven of eight patients (87.5%) following 2 weeks' and 10 weeks' treatment, respectively. However, one patient with refractory anemia had a delayed favorable response in erythrocyte and neutrophil counts at week 14 in spite of the cessation of combination therapy at week 10. These results indicate that combination therapy with rhG-CSF and rhEPO is not beneficial to patients with MDS, based on the presently used protocol.
