    Notes: Abstract An anti-inflammatory factor (AIF) was highly purified from normal bovine serum. The purified AIF was a polysaccharide which was formed from a low molecular substance Pro-AIF by macromolecularization. AIF showed potent inhibitory activities against carrageenin induced edema in rats and PMN-leucocyte chemotaxis. It showed no inhibition in cutaneous reaction with serotonin, bradykinin or a mediator releaser compound 48/80. No inhibition was also observed in thermally induced pain, reversed passive Arthus reaction and adjuvant polyarthritis in rats. With these results, the role of AIF in inflammation was discussed.

    Notes: Summary Candida albicans produces a major extracellular proteinase whose activities are observed only in weakly acidic pH. However, in affected lesions, a variety of pH conditions exist, including neutral pH. To verify the pathological importance of the extracellular proteinase, the correlation between culture medium pH, extracellular proteinase activity, and cell growth of C. albicans was followed for 3 weeks with unbuffered and insoluble stratum corneum-supplemented liquid media. Each medium pH, initially adjusted within a range of pH 3–7 by the addition of sodium hydroxide or hydrochloric acid solution, was acidified, and a subsequent high proteolytic activity and rapid fungal growth were observed. After full fungal growth, neutralization of each medium to pH 7 and reduction of proteinase activity occurred. Results from a glucose addition experiment suggest that acidification of each medium was produced by the acid formation from glucose and neutralization by the exhaustion of glucose and increase of ammonia from denatured stratum corneum. These data suggest that extracellular proteinase from C. albicans could act as a virulence factor under a wide range of pH conditions by the acidification of the environmental pH close to the organism.

    Effect of oxygen on the corrosion of dental amalgam (1985)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: The anodic and cathodic polarization of five dental amalgams were determined as a function of oxygen concentration in Ringer's solution and artificial saliva. The results indicate an anodic polarization behaviour dependent on Cl ion concentration and a corrosion potential determined primarily by oxygen concentration. At high oxygen concentrations the corrosion rates of traditional and copper enriched amalgams were equivalent.

    Polyribosome metabolism, growth and water status in the growing tissues of osmotically stressed plant seedlings (1985)

    Notes: Relationships between growth of osmotically stressed intact seedlings and polyribosome levels and water status of growing tissues were examined. Sudden exposure of barley (Hordeum vulgare L. cv. Arivat) roots to a solution of −0.8 MPa polyethylene glycol caused leaf growth to stop almost immedately, but growth resumed at a much lower rate after 0.5–1 h. In the growing region of leaves, the polyribosome: total ribosome ratio of free (non-membrane-bound) ribosomes was significantly reduced after 15 min stress, but a decrease in the large polyribosome:total polyribosome ratio occurred only after 1–2 h. Membrane-bound and free polyribosome levels both decreased to 70% of unstressed control values after 4 h stress. Recovery of total polyribosomes occurred within 1 h after relief of 4 h stress, but required 3 h after relief of 24 h stress. Stress detectably reduced the water potential and osmotic potential of growing tissue within 0.5–1.0 h, and osmotic adjustment continued for up to 10 h. Recovery of water status was incomplete after 1 h relief of a 4 h stress. In contrast, expanded blade tissues of stressed plants underwent minor changes in water status and slow decreases in polyribosomes levels. These results confirm that growing tissues of barley leaves are selectively responsive to stress, and suggest that changes in growth, water status and polyribosome levels may be initiated by the same signal. Measurements of seedling growth, polyribosome levels and water status of growing tissues of barley and wheat (Triticum aestivum L. cv. Zaragoza) leaves, etiolated pea (Pisum sativum L. cv. Alaska) epicotyl and etiolated squash (Cucurbita pepo L. cv. Elite) hypocotyl stressed with polyethylene glycol solutions of −0.3 to −0.8 MPa for 12 h or more showed that polyribosome levels were highly correlated with seedling growth rate as well as with tissue water and osmotic potentials, while turgor remained unchanged. These results suggest that long-term growth of osmotically stressed plants may be limited by a reduced capacity for protein synthesis in growing tissues and is not dictated by turgor loss.

    Description / Table of Contents: Übersicht Durch Anwendung des Verfahrens von Galerkin auf die Donnellschen Grundgleichungen werden praktisch genaue Lösungen für das Nachbeulverhalten von eingespannten Kreiszylinderschalen gewonnen, die einer Torsion unterworfen sind. Über detaillierte Rechnungen für einen weiten Bereich von Schalengeometrien wird geklärt, wie Verdrehung, Stauchung und Nachbeulverformung mit dem gegebenen Torsionsmoment zusammenhängen. Die Ergebnisse stimmen mit experimentell ermittelten Werten gut überein.
    Notes: Summary Applying the Galerkin procedure to the Donnell basic equations, fairly accurate solutions are obtained for the postbuckling behavior of clamped circular cylindrical shells subjected to torsion. Through detailed calculations, main postbuckling characteristics, i.e., connections of the angle of twist, axial shortening and deflection with applied torque, are clarified for a wide range of shell geometrics. The results here obtained are ascertained to be in good agreement with the corresponding experimental results.

    Experiments on the postbuckling behavior of circular cylindrical shells under compression (1975)

    Notes: Abstract Detailed experimental studies are performed on the postbuckling behavior of circular cylindrical shells under compression, by using polyester test cylinders with the geometric parameterZ ranging from 20 to 1000. In each case, variations of the equilibrium load, circumferential wave number and maximum inward and outward deflections, with applied edge shortenings, are clarified. Contour lines for typical postbuckling configurations are also shown. It is found that, as the cylinder is compressed beyond the primary buckling, secondary bucklings take place successively with diminishing wave numbers, and that postbuckling equilibrium loads become significantly lower than those at buckling asZ increases. Further, for short shells withZ≦100, the buckled waveforms are always symmetric with one-tier diamond buckles, while for longer shells, asymmetric postbuckling patterns with two tiers of buckles dominate.
