    Notes: Multilayer reflectors and position sensitive detectors have been developed in constructing imaging optical systems in the 45–300 A(ring) region. Molybdenum-silicon (2d=140 A(ring), N=20) and nickel–carbon (2d=100 A(ring), N=20) multilayers were deposited on a spherical mirror (25 cm in diameter) for the normal incidence and on a segment of paraboloidal mirror (20 cm×10 cm) for 30° grazing incidence. Their optical characteristics were evaluated by using characteristic x rays and monochromatized synchrotron radiation in the 45–300 A(ring) region. A position sensitive detector is made of a tandem microchannel plate (MCP) with a CsI photocathode and resistive plate, which is placed at the focal plane of each mirror. The detection efficiency and position resolution were measured by using characteristic x rays of CKα and monochromatized synchrotron radiation in the 45–200 A(ring) region.

    Notes: Pb1−x−yCdxSry S/PbS/Pb1−x−yCdxSryS double-heterostructure lasers emitting at a midinfrared wavelength region were fabricated for the first time using molecular beam epitaxy. Effects of the lattice mismatches between active and confinement layers and also between substrate and confinement layers using a tilted substrate on the laser properties were investigated. The maximum pulsed operating temperature increases as the lattice mismatch decreased using a tilted substrate.

    Notes: Barium titanate thin films were deposited on metallic conducting BaPbO3 ceramic substrates by the sol-gel method using metal alkoxides. The thin films with a thickness of around 0.4 μm were confirmed to have a perovskite structure and to be highly resistive with a resistivity of more than 1011 Ω cm at room temperature. The typical dielectric constant and dissipation factor of the films were 600 and less than 2% (1 kHz), respectively, at room temperature. From ferroelectric hysteresis measurements a remnant polarization of around 1.5 μC/cm2 and a coercive field of about 28 kV/cm were obtained for the films.

    Notes: A 73-year-old woman had a walnut-sized tumor in I he occipital region for 10 year. The growth consisted of multiple small and large cystic epithelial masses. The cyst wall exhibited trichilemmal keratinization. Numerous squamous eddies as well as many glycogen-rich cells were present in the cyst wall. Some small round keratohyalin granules were observed in the cells below the horny layer. The desmosomes and masses of lipid droplets were seen in the horny layer. The findings described above are similar to those observed in the follicular isthmus and the follicular infundibulum. Other interesting findings include the presence of intranuclear inclusions of tonofilament-like material and/or keratohyalin-like granules within the cells near the mid-layer of the cyst wall.

    Modification of the hyperosmotic infiltration method of vaccination against vibriosis in cultured ayu, Plecoglossus altivelis Temminck and Schlegel (1984)

    Notes: Abstract. A vaccine solution of a formalin-killed culture of Vibrio anguillarum cells was observed to be toxic to young ayu when administered by the hyperosmotic infiltration method. The toxin was present in the culture broth. After the toxin was removed from the broth by centrifugation, the fish were dipped in 5.32% NaCl solution for 2 min and then in a solution containing precipitated cells for 3 min. The immunized fish were protected against vibriosis when challenged one month after immersion. The bacterin was administered to ayu by a further two methods, both using lyophilized whole cells of formalin-killed V. anguillarum. In one method, the fish were placed in a 5.32% NaCl solution for 2 min and then in a solution containing lyophilized cells at 2 g/l of well water for 3 min (two-step immersion). In the other method, the fish were placed in a 5.32% NaCl solution containing lyophilized cells also at 2 g/l for 3 min (one-step immersion). A high level of protection against artificial challenge was achieved with either method. No agglutinating antibodies to V. anguillarum were detected in either the serum or mucus of fish dipped in a vaccine solution, a supernatant, or a precipitated solution, one month after immersion. On the other hand, serum titres were detected in fish vaccinated by injection, although no titres were detected in mucus. LD50 values are presented for the virulence of the V. anguillarum strain. Compared to the original strain, virulence increased after the third passage in ayu, but decreased after the thirteenth passage in medium.

    The effect of age on concentrations of monoamines, amino acids, and their related substances in the cerebrospinal fluid (1993)

    Notes: Summary We studied age-related changes in the concentrations of monoamines, amino acids, and their related substances in the cerebrospinal fluid on 144 neurologically normal subjects. The concentrations of tyrosine, 3-O-methyldopa, dopamine (total), norepinephrine (total), homovanillic acid, p-hydroxyphenylacetic acid, and 5-hydroxytryptophan increased significantly with age (p〈0.05), and the concentration of 3.4-dihydroxyphenylacetic acid displayed a non-significant trend to decrease, whereas concentrations of other monoamine precursors and metabolites were unchanged. We found the significant positive correlations between the concentrations of HVA and 5-HIAA (p〈0.001), between tyrosine and tryptophan (p〈0.001), and between tyrosine and 3-O-methyldopa (p〈0.001). The concentrations of asparagine, glycine, taurine, and alanine increased significantly with age (p〈0.05), while glutamine, arginine, and threonine concentrations did not change with age. The aspartate, glutamate, and GABA concentrations displayed the non-significant trends to decrease in the elderly subjects. The concentrations of aspartate, glutamate, and GABA had mutually significant positive correlations (p〈0.05), but had significant negative correlations with the concentrations of some neutral amino acids. The urate and xanthine concentrations increased significantly with age (p〈0.01). These findings suggest that the concentrations of monoamine and amino acid transmitters and their related compounds in the cerebrospinal fluid reflect age-related changes in the synthesis, release, and reuptake mechanisms of the transmitters and their transport mechanisms across the blood-brain barrier.

    Notes: Summary We studied the effects of L-threo-DOPS (L-DOPS) on the concentrations of total (conjugated and unconjugated) dopamine (DA) and norepinephrine (NE) in the cerebrospinal fluid (CSF) of parkinsonian patients with freezing phenomenon. The NE concentration increased remarkably and dose-dependently after administration of L-DOPS in both L-dopa/carbidopa-pretreated and untreated patients. The DA concentration also increased mildly but significantly in L-dopa/carbidopa-untreated patients. Freezing phenomenon improved in 6 out of 8 patients at Hoehn and Yahr's stage III, and 1 out of 5 patients at stage IV. These results indicate that L-DOPS administration increases the NE concentration dosedependently, and is effective for freezing of gait of moderate severity.

    Monoamine metabolism in the cerebrospinal fluid in Parkinson's disease: relationship to clinical symptoms and subsequent therapeutic outcomes (1993)

    Notes: Summary We correlated monoamine concentrations in the cerebrospinal fluid from de novo (untreated) patients with Parkinson's disease with their clinical symptoms and therapeutic outcome after two years of L-dopa with/without other anti-parkinson medication. A significant correlation was found between the severity of some parkinsonian symptoms and the reduction in particular monoamines: Hoehn and Yahr's stage with dopamine, norepinephrine, and homovanillic acid: rigidity with dopamine; akinesia with dopamine and norepinephrine; freezing of gait with norepinephrine; and dementia with dopamine and homovanillic acid. Tremor had no correlations with the concentrations of the monoamines measured. Patients with dementia had a significantly increased level of epinephrine concentrations. Insufficient therapeutic responses of invidividual symptoms were associated with significantly decreased concentrations of particular monoamines before treatment: Hoehn and Yahr's stage with norepinephrine and epinephrine; akinesia with homovanillic acid and 5-hydroxyindoleacetic acid; and freezing of gait with dopamine, norepinephrine, homovanillic acid, and 5-hydroxyindoleacetic acid. These results suggest a significant correlation between the reduction in particular monoamines and the severity of some parkinsonian symptoms and their subsequent responses to L-dopa.
