    Two patients with meningioma visualized as high uptake by SPECT with N-isopropyl-p-iodo-amphetamine (I-123) (1988)

    Notes: Summary It has been reported that brain tumors show decreased IMP uptake, however, we encountered two cases of meningioma which had initially increased IMP uptake. SPECT was performed at 30 min, 2 hr and 6 hr after intravenous administration of IMP (3 mCi). The delayed images (2 and 6 h) showed decreased IMP uptake. These were convexity and parasagittal meningiomas which had tumor stains at angiography. Although the mechanism of IMP uptake in brain tumor is still unclear, this finding should be considered in the interpretation of IMP-SPECT.

    Tetrodotoxin-producing bacteria from the blue-ringed octopus Octopus maculosus (1989)
    Springer

    Topics: Biology
    Notes: Abstract Several live specimens of the blue-ringed octopus Octopus maculosus were collected from the Philippines in November 1985, and from Japan in February 1986, and the distribution of toxicity, along with toxin composition, in the posterior salivary gland and other soft parts were examined. Tetrodotoxin (TTX: 1400 mouse units g-1) was detected in the posterior salivary gland of a Japanese specimen, while not only the salivary gland but other soft parts were toxic in the Philippine specimens. The Philippine specimens contained TTX and anhydrotetrodotoxin, the Japanese specimen TTX, 4-epitetrodotoxin, and an unknown toxin. The posterior salivary gland, intestine and other parts were excised from the Philippine specimens and examined for bacterial flora. Twenty-two dominant strains were isolated and cultured in a 2xORI medium (Ocean Research Institute, Simidu and Tsukamoto 1985) at 20°C for 20 to 48 h. Cells were harvested by centrifugation, and disrupted by ultrasonication. The toxins were partially purified from the cell lyzate by ultrafiltration and Bio-Gel P-2 column-chromatography. Instrumental analyses disclosed that 16 of the 22 strains produced TTX and/or related substances. Six strains which clearly exhibited TTX productivity were identified as Alteromonas (2 strains), Bacillus (2), Pseudomonas (1) and Vibrio (1), based on biochemical and biological characteristics. Of these, one strain each of Bacillus and Pseudomonas produced TTX at a level detectable by the mouse assay.

    Changes in microflora of a puffer fish Fugu niphobles, with different water temperatures (1989)
    Springer
    Marine biology 101 (1989), S. 299-304 
    Details
    ISSN: 1432-1793

    Topics: Biology
    Notes: Abstract Grass puffer Fugu niphobles, captured in November 1986 at Shimoda, Japan, and then reared at different temperatures ranging from 10 to 29°C, was examined for microflora changes in the skin, gill and intestines. At 10°C, the skin and gill were colonized mainly by Pseudomonas, Flavobacterium and Moraxella, while at 29°C Vibrio and Flavobacterium appeared abundantly. The intestinal microflora, consisting of Vibrio, Pseudomonas and Flavobacterium, revealed little temperature dependence, although the intrageneric composition of Vibrio changed conspicuously depending on the change of water temperature. Vibrio group 1, tentatively identified as V. alginolyticus, was detected in all tissues examined at 20 and 29°C. This, along with the fact that V. alginolyticus produces tetrodotoxin, suggests that the tetrodotoxin contained in puffer is, at least partly, accounted for by this bacterial species inhabiting intestines.

    Pathogenesis of pili annulati (1988)
    Springer
    Archives of dermatological research 280 (1988), S. 308-318

    ISSN: 1432-069X
    Keywords: Pili annulati ; Ultrastructure ; DACM staining ; Hair cortex ; Protein metabolism

    Topics: Medicine
    Notes: Summary Plucked scalp hairs and hair roots of pili annulati were examined to understand their pathogenesis. Stereoscopic examinations of hairs in transmitted light and/or reflected light and light microscopic surveys of the cross-sections of hairs confirmed that the cortical empty spaces appeared to be responsible to the unique dotted shiny appearance of the hairs seen by the unaided eyes under a refracted light. By transmission electron microscope, small vacuoles and dense bodies were observed in the cytoplasm of the differentiating cortical cells; subsequently, with increasing number of tonofilaments, an uneven distribution of free ribosomes occurred and abnormal spaces containing fine granular substances were formed in the cytoplasm of the cortical cells. Occasionally, extremely large cortical trichohyaline granules were found. In the keratinized hair, irregular empty spaces were present in the cortex of the abnormal hair segments. Histochemically, the keratinized cortex of the affected hairs always had more residual SH groups than the controls. Pili annulati may be a disorder of protein metabolism involving a partial dysfunction of cytoplasmic ribosomes, resulting in a lack of cortical keratin formation.

    Antikeratin autoantibodies in the amyloid deposits of lichen amyloidosus and macular amyloidosis (1989)
    Springer
    Archives of dermatological research 281 (1989), S. 377-382

    Keywords: Lichen amyloidosus ; Macular amyloidosis ; Antikeratin autoantibodies

    Topics: Medicine
    Notes: Summary In order to characterize immunoglobulins found on amyloid deposits of lichen amyloidosus and macular amyloidosis, an elution from cryostat sections was performed with citrate buffer, glycine buffer, NaCl, and PBS. Resulting eluates (mainly IgG) were examined with dot immunoblotting and SDS-PAGE immunoblotting and were found to react with the human epidermal keratin of 50 and 67 kD. Antikeratin autoantibody activities in normal murine and human sera were examined using a dot immunoblotting assay. In murine sera, titers of IgG and IgM autoantibodies were higher in older mice. The human cord blood showed significantly lower IgM autoantibody titers, whereas IgG antibody titers showed no significant differences from adults' sera, probably due to the permeability of IgG through the placental barrier. A stronger antibody activity in older individuals was thought to be due to the repeated exposures to keratin proteins derived from apoptotic keratinocytes. Sera from lichen amyloidosus and macular amyloidosis patients did not show any difference from normal controls in their antikeratin titers. It was concluded that the patients with lichenoid or macular amyloidosis are capable of producing a normal level of antikeratin autoantibodies. However, the removal of opsonized keratin-type amyloid from the skin is slow or deficient due to as yet unknown factors.

    Notes: Abstract Chlorobis/β-diketonato/ oxotechnetium/V/ complexes [TcOCl/β-dik/2, β-diketone=acetylacetone, benzoylacetone and dibenzoylmethane] were newly synthesized using macroamount of99Tc. These complexes were further separated into geometrical isomers. Furthermore, an improvement of the yields for the syntheses of tris/β-dike-tonato/technetium/III/ complexes [Tc/β-dik/3, β-diketone=acetylacetone, benzoylacetone and 2-thenoyltrifluoroacetone] was examined using Tc/III/-thiourea complexes as a starting material.

    Pionic X-ray intensity ratios in chromium compounds (1989)

    Notes: Abstract Pionic X-ray intensity ratios in chromium compounds were compared with those from muonic X-rays. The ratios were found depending on the μ− capture ratio as on μ− capture. The difference of the ratios between Cr/H2O/6Cl3 and CrCl3 was attributed to the formation of pseudoneutron μ− by interaction of hydrogenic protons during passage of a pion in the hydrated compound.
