    Notes: The coercive forces and anisotropy fields of Fe-Ru-Ga-Si films deposited on 30° tilted substrates were measured for varying chemical compositions and crystal orientations. The minimum coercivity and minimum in-plane magnetic anisotropy were observed at an iron-rich composition corresponding to a substantial magnitude of anisotropy constant: K1=6×103 (J/m3). From an orientation analysis of the crystal aggregate, this optimization with the large K1 was understood to be a result of the cancellation of the shape anisotropy by the crystalline anisotropy.

    Notes: To advance new soft magnetic materials of an FeGaSi alloy into the commercial world, improvements on various properties were designed by introducing additive elements without sacrificing its high saturation magnetic induction. The detailed studies on the diversified properties, such as saturation magnetic induction, film internal stress, wear resistivity, and so on, were performed. High-frequency permeability of the laminated structure film was also investigated. As a result, the Ru-added FeRuGaSi alloy films, whose typical compositions are Fe72Ru4Ga7Si17 and Fe68Ru8Ga7Si17 (at. %), prove to be excellent soft magnetic materials especially appropriate for the magnetic recording/playback head core use.

    Notes: Magnetic and other properties of Co-base amorphous alloy films prepared by sputtering are investigated. A detailed magnetic phase diagram with saturation magnetic flux density, crystallization temperature, and zero-magnetostrictive line on Co-Ta-Zr amorphous alloys were obtained, and the technical knowhow to make a film with well-reproducible characteristics by widely changing the sputtering conditions was related with these physical properties. Especially on alloy sputtering, a phenomenological model for elucidating a composition difference between film and target is presented. After these studies, the film characteristics of Bs=12 kG, Tx=450 °C, ||λs||〈10−8, Hc〈10 mOe, and permeabilities of μ(1 MHz)=7000, μ(100 MHz)=2000 for the single film of 2 μm in thickness and of μ(1 MHz)=4000, μ(100 MHz)=800 for the insulator-sandwiched multilayered film of 10 μm are obtained, and these well-balanced values enable us to apply the materials for high-frequency recording head.

    Notes: Extensive study was made on Fe-base crystalline alloys in search for new soft magnetic materials with high saturation magnetization by means of sputtering technique. It revealed that newly found FeGaSi and FeAlGe alloy systems possessed excellent soft magnetic properties with remarkably higher saturation magnetization. These new alloy films, annealed in vacuum at 500 °C for 1 h, show the magnetic properties of Bs=13 and 15 kG, Hc=0.09 and 0.20 Oe, and μ1 MHz=2000 and 1800 for the FeGaSi and FeAlGe alloy films of 2 μm in thickness, respectively. These values are superior to those of FeAlSi (sendust) alloy which is a typical soft magnetic material with high saturation magnetization. Results of the Co-added systems of FeCoGaSi and FeCoAlGe alloys are also presented. Discussions are given on various systems of Fe base crystalline alloy films studied, which are classified into four types of groups with respect to magnetic softness.

    Notes: To clarify the significance of basic fetoprotein (BFP) in lymphocytes, we investigated whether BFP is produced in lymphocytes during blastic transformation. Peripheral blood lymphocytes obtained from 14 adults were cultured under the stimulation of lectins. The concentration of BFP in the culture medium (extracellular BFP) was estimated serially. The incorporation of [6-3 H] thymidine was assayed simultaneously. The intracellular BFP was measured by dual flow cytometry for DNA and BFP. A lymph node was studies immunohistochemically. Serum BFP was measured in four cases of lumphocytic leukaemia. In two cases, dual staining was performed. The intracellular BFP of the mitogen-stimulated lymphocytes was increased within 24 h. The extracellular BFP was increased exponentially from 72 h. The extracellular BFP at 96 h did not correlate with the [3H]-thymidine incorporation. The intracellular BFP increase began in G1 phase. Immunostaining showed that the B cells also produced BFP. Theserum BFP level in leukaemia was high in 1 of 4 cases and the leukaemic cells in two cases showed high intracellular BFP content. These observations indicate that BFP is produced in activated human lymphocytes and in lymphocytic leukaemic cells. The production of BFP during blastic transformation will be a useful new in vitro model for studying the biological role of BFP, and BFP labelling may offer some new possibilities for study of lymphocytes.

    Notes: The definition of a lattice and its superlattice is given algebraically. A coincidence site lattice (CSL) is defined as an intersection lattice of any two crystal lattices, and a complete pattern-shift lattice (DSCL) as the set theoretically smallest lattice containing both crystal lattices as superlattices. In the case where the two lattices are related by a non-singular matrix (having non-zero determinant), the so-called 0-lattice may be generated from the two crystal lattices. Any translation of the 0-lattice by all the vectors of one of the crystal lattices forms a lattice, i.e. a reduced 0-lattice. As a result of the theory of groups and numbers, the reduced 0-lattice (abbreviated to ROL) is homomorphic to the DSCL. It is shown that the factor group of all cosets of lattice 1 in the DSCL (in the ROL) is isomorphic with the factor group of all cosets of the CSL in lattice 2 (in the 0-lattice). The volume of a unit cell is derived for all the lattices generated by the two crystal lattices. Secondly, the reciprocal of a lattice is introduced and the reciprocity between the CSL and the DSCL determined by the reciprocals of the two crystal lattices is shown as a special case of a theorem mentioned about modules over a ring. Finally a complete diagram of relationships between b-lattices and 0-lattices for direct lattices and reciprocal lattices is given.

    Notes: Abstract We present a case of Dandy-Walker malformation associated with occipital meningocele, microphthalmia, and cleft palate. Small numbers of cases of Dandy-Walker malformation with occipital meningocele have been described in the literature, but to our knowledge, non of these also had microphthalmia or cleft palate. This association suggests that time of intrauterine origin of Dandy-Walker syndrome was in the sixth or seventh embryonic week. In the diagnosis, both CT cisternography and direct neurosonography over the occipital meningocele was useful for the demonstration of a posterior fossa cyst which communicated with the fourth ventricle and the occipital meningocele.

    Description / Table of Contents: Zusammenfassung Eine einfache und schnelle Methode zur Analyse von Barbituraten im Serum wurde entwickelt. Zur Probenaufarbeitung wurde eine Säulenextraktion mit Hilfe von Extrelut und Florisil angesetzt. Das Eluat wurde direkt analysiert mit Hilfe der GC/MS (EI-SIM). Als Ionen wurden die „base peaks” von 10 verschiedenen Barbituraten ausgewählt. Als interner Standard wurde Allobarbital oder Secobarbital verwendet. Innerhalb eines Bereiches von 0,5–5 ng wies die Eichkurve einen linearen Verlauf auf. Bei der Extraktion von gespeikten Serumproben, welche 20 μ1,5 ml und 5 μ1,5 ml enthielten, konnte eine Wiederfindungsrate von 87,2–105,2% und 81,6–104,6% gefunden werden. Phenobarbital stellt mit einer Wiederfindungsrate von 151,9% bzw. 172,1% eine Ausnahme dar. Die Secobarbital-Gehalte von 13 Patienten-Seren nach intravenöser Gabe von Secobarbital wurden analysiert. In 3 von 10 Fällen konnten Secobarbital-Spiegel von mehr als 1 μg/ml bei mehr als 72 Stunden zurückliegender Secobarbital-Gabe nachgewiesen werden. Die Methode scheint eine Möglichkeit zur klinischen Barbiturat-Spiegel-Bestimmung zu bieten.
    Notes: Abstract A simple and rapid method for analysis of barbiturates in serum has been developed. In order to extract and clean barbiturates in serum, a separation column packed with Extrelut and Florisil was used, and the eluate was directly analyzed by means of electron impact selected ion monitoring (EI-SIM). Selected ions used were base peak ions of 10 barbituartes, and the internal standard used was allobarbital or secobarbital. The calibration curves were linear over the range 0.5–5 ng. Extraction of replicate serum samples containing 20 μg/1.5 ml and 5 μg/1.5 ml resulted in a recovery of 87.2–105.2% and 81.6–104.6%, respectively, with the exception of phenobarbital, which was 151.9% and 172.1%, respectively. Secobarbital was also analyzed in the serum of 13 patients who had been given secobarbital intravenously. In 3 out of 10 cases, Secobarbital levels greater than 1 μg/ml were detected more than 72 h after administration. This method seems to have possibilities for clinical use.

    Notes: Summary Japanese encephalitis virus antigens were immunohistochemically demonstrated in formalin-fixed paraffin sections from an autopsied brain. Glial nodules were always associated with antigen-positive cell debris. Glia shrubs in the cerebellar cortex appeared to be formed along the apical dendrite of Purkinje cells. Most, but not all, of the neurons involved in neuronophagia were viral antigen positive. Antigenic masses were occasionally encountered in the center of so-called acellular plaques. Neurons with strong viral antigens were sporadically found in normal-appearing regions in the thalamus and cerebral cortex. Viral antigens were demonstrable only in neurons and not in glial or vascular endothelial cells.
