    Notes: The aim of this study was to develop rapid and accurate procedures to identify microorganisms contaminating cosmetic products, based on the identity of the nucleotide sequences of the internal transcribed spacer (ITS) region of the ribosomal RNA coding DNA (rDNA). Five types of microorganisms were isolated from the inner portion of lotion bottle caps, skin care lotions, and cleansing gels. The rDNA ITS region of microorganisms was amplified through the use of colony-direct PCR or ordinal PCR using DNA extracts as templates. The nucleotide sequences of the amplified DNA were determined and subjected to homology search of a publicly available DNA database. Thereby, we obtained DNA sequences possessing high similarity with the query sequences from the databases of all the five organisms analyzed. The traditional identification procedure requires expert skills, and a time period of approximately 1 month to identify the microorganisms. On the contrary, 3–7 days were sufficient to complete all the procedures employed in the current method, including isolation and cultivation of organisms, DNA sequencing, and the database homology search. Moreover, it was possible to develop the skills necessary to perform the molecular techniques required for the identification procedures within 1 week. Consequently, the current method is useful for rapid and accurate identification of microorganisms, contaminating cosmetics.

    Ultrastructure of transplant glomerulopathy (1980)

    Notes: Thirty-one specimens of tissue were obtained from 15 renal allografts 3–96 months after transplantation and studied by light, electron and in some cases also by immunofluorescence microscopy. All patients had a degree of renal insufficiency and almost all had proteinuria and moderate hypertension; nephrotic syndrome was present in one and hematuria in two. On histological examination one patient showed cellular proliferation suggestive of glomerulonephritis (recurrent or de novo) and another patient had numerous crescents. The most frequent glomerular lesion was widening of the lamina rara interna with subendothelial accumulation of finely granular material, formation of new subendothelial basement membrane and deposition of microfibrils and fine filaments. The mesangial changes were mainly those of mesangiolysis and mesangial sclerosis with deposition of mesangial matrix and microfibrils, but little cellular proliferation. Fragmented red blood cells were seen in nearly half of the patients. In another seven patients the lesion resembled focal segmental glomerulosclerosis. This combination of changes termed transplant glomerulopathy leads to diffuse glomerular sclerosis. Arterial intimal thickening and occasionally also thrombosis produced ischaemic changes in the kidney and in the glomeruli and contributed significantly to the process of transplant rejection.

    Notes: Background  Dapsone (4,4′-diaminodiphenyl sulphone) is a powerful therapeutic tool in many skin diseases including neutrophilic dermatoses. The drug has an outstanding therapeutic efficacy against many skin diseases characterized by neutrophil-rich infiltrates; however, mechanisms of its action are poorly understood.Objectives  We investigated the effects of dapsone on respiratory and secretory functions of human neutrophils triggered by the chemotactic peptide N-formyl-L-methionyl-L-leucyl-L-phenylalanine (fMLP), the physiological agonist C5a, and phorbol myristate acetate (PMA).Methods  Human neutrophils were isolated from venous blood obtained from healthy donors. We detected extracellular production of superoxide (O2–) by cytochrome C reduction assay, and intracellular production of O2– by flow cytometry. Neutrophil elastase release was measured by the cleavage of the specific elastase substrate N-methoxysuccinyl-Ala-Ala-Pro-Val-p-nitroanilide. Measurement of cytosolic free calcium concentration was performed using the calcium-reactive fluorescence probe, Fluo-3.Results  Dapsone suppressed intra- and extracellular production of O2– and elastase release triggered by fMLP and C5a, but not by PMA. Both fMLP and C5a signalled the above pathways by inducing calcium influx, but PMA functions bypassed calcium influx. Dapsone was capable of antagonizing the induction of calcium influx.Conclusions  These findings suggest that one mechanism of the anti-inflammatory action of dapsone is inhibition of calcium-dependent functions of neutrophils including release of tissue-damaging oxidants and proteases in the affected skin.

    Notes: Abstract A lithium isotope separation was performed using a laser isotope separation method. It was found that the lithium atoms with a natural isotopic abundance enhanced its6Li concentration up to over 90% by tuning the laser wavelength to the2 P 1/2 of6Li. Too high power, however, leads to a loss of enrichment due to the power broadening effect which was analysed by the equation of motion of density matrices.

    Notes: In this study, the influences of carbides and alloy additives on ground surfacecharacteristics of several high Chromium (Cr) steels and abrasive grains of working surface werediscussed. In the grinding using metal bonded CBN wheel, almost constant values in groundsurface roughness and high grinding ratio were shown. 5% Cr steel with Vanadium, 8% Cr steeland 10% Cr steel showed a rougher surface than Cr steels with 3%, 4% and 5% due to the carbideinclusion. The grinding ratio of 5%Cr steel could be raised considerably by adding sulfur to it

    Notes: The fundamental experiment of the grinding of the stainless steel using the metal bondedCBN wheel which was excellent in wear resistance was conducted. The most appropriate grindingconditions were obtained by clarifying wear process of grinding wheel and finished ground surfacequality. When grinding was carried out up to stock removal 7000mm3/mm, radial wear of grindingwheel %R is 3μm and surface roughness Rz was 0.5μm or less. The grinding ratio Gr becomesabout 3000, and long life grinding with little change of surface roughness was possible
