    Changes in microflora of a puffer fish Fugu niphobles, with different water temperatures (1989)

    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.

    Vibrio alginolyticus, a tetrodotoxin-producing bacterium, in the intestines of the fish Fugu vermicularis vermicularis (1987)

    Notes: Abstract To clarify the mechanism of toxification in animals contaminated with tetrodotoxin, the intestinal contents of the puffer Fugu vermicularis vermicularis were examined for bacterial flora in 1985. Twenty-six out of 33 strains belonged to the genus Vibrio. These bacteria were classified into Groups I to VII, based on biological and biochemical characters. High performance liquid chromatography and gas chromatography-mass spectrometry, together with mouse bioassay for toxicity, clearly demonstrated that Group I produced tetrodotoxin and anhydrotetrodotoxin under cultivation with a medium composed of Phytone peptone (BBL) and NaCl. Some other groups also produced this toxin and/or related substances to some extent. Strains of Group I were all identified as Vibrio alginolyticus. Two strains among four produced a detectable amount of tetrodotoxin and/or anhydrotetrodotoxin, as measured by all instrumental analyses applied. Our findings suggest that some strains of V. alginolyticus are closely related to the toxification of the puffer, and probably of other species.

    The establishment of an intestinal microflora in developing goldfish (Carassius auratus) of culture ponds (1988)

    Notes: Abstract The bacterial flora in the intestinal tract of goldfish (Carassius auratus) was investigated at different stages of fish development. The floras of the diets and the water and sediment of a culture pond were also analyzed. The total counts in the intestine ranged from 2.2 × 106−2.1 × 108 cells g−1 wet weight.Aeromonas hydrophila, A. punctata, Pseudomonas, Bacteroidaceae andClostridium species were the common components in the intestinal tract of goldfish from larvae to adult stage.Bacteroides type A appeared at 44 days with a density of 103 cells g−1 and then predominated with densities of 105−107 cells g−1. The intestinal microflora of goldfish become relatively stable after 67 days of hatching. These observations suggest that the intestinal microflora of adult goldfish becomes established approximately 2 months after hatching.

    Determination of calcium in chlor-alkali brine by flow injection analysis (1985)

    Notes: Summary Determination of Calcium in Chlor-alkali Brine by Flow Injection Analysis A few milligrams of calcium in one liter of chlor-alkali brine were determined by flow injection analysis. When the calcium content was lower, the preconcentration and separation of calcium from sodium chloride with a chelating resin column was employed. The flow injection analysis was based on the exchange reaction between calcium and zinc complex of ethylene glycol-bis(2-aminoethylether)tetraacetic acid (EGTA) in the presence of 2-(3,5-dibromo-2-pyridylazo)-5-[N-ethyl-N-(3-sulfopropyl)amino]phenol(H2R): $$Ca^{2 + } + Zn(EGTA) + 2R \rightleftharpoons ZnR_2 + Ca(EGTA)$$ . Calcium (0.25–2.0 mg 1−1 in the presence of magnesium, iron(III), aluminum, copper(II), nickel, phosphate, chloride, sulfate and carbonate can be determined with a sampling rate of 40 h−1.

    Creep behaviour in unloading process of cellulose nitrate under superimposed tensile and hydrostatic loading (1982)

    Notes: Abstract The creep behaviour in unloading process under various combinations of superimposed tensile and hydrostatic loading are quantitatively investigated using non-linear-viscoelastic cellulose nitrate heated at 65° C. The creep strain and the creep strain-rate in the unloading process are quite influenced by the effect of hydrostatic pressure, but are not so influenced as those in the loading process mentioned in a previous paper. The deformation properties in the unloading process are also discussed with experiments for proportional loading (namely, uniform rate of stress increases or decreases with time). The stress-strain relation in the unloading process of the creep behaviour under superimposed loading is deduced by using the invariant theory. The deduced relation gives good agreement with the actual observations under the superimposed loading.
