    Notes: Summary In a study undertaken to investigate the relationship between vibration syndrome and collagen disease, 90 Japanese patients with vibration syndrome (all men aged 41–86 years) were examined immunologic abnormalities, mainly by a set of immunoserology tests. Of these 90 patients, 25 had examinations at yearly intervals for 3 consecutive years, while the other 65 underwent examinations once. The results indicate that, of all the patients studied, 10 (11.1%) gave a positive RA test, 6 (6.7%) had leukopenia, 5 (5.6%) had hypergammaglobulinemia, and 15 (16.7%) had hypocomplementemia (CH50). Worthy of particular note are the 21 patients (23.3%) who were positive for nuclear-specific antibodies (1: ≥ 40) (using Hep-2 cells as the nuclear substrate), with some of them suspected of having Sjögren's syndrome, progressive systemic sclerosis, or systemic lupus erythematosus. During a 3-year follow-up period, 10 (40%) of 25 patients exhibited rising titers of nuclear-specific antibodies with conversion to seropositivity for these antibodies. The facts that the positivity rate for nuclear-specific antibodies was significantly higher in these patients with vibration syndrome (23.3%) than in healthy adult men over 40 years of age (1.8%) (P 〈 0.05) and that a progressive elevation of nuclear-specific antibody titer was noted in a high percentage of the patients were suggestive of some causal relationship between the appearance of nuclear-specific antibodies and the use of vibrating tools.

    Notes: In this work several polyorganosilylenes were synthesized including homo-and copolymers containing SiMe2 and SiPh2 units. A Wurtz-type coupling reaction of the respective dichlorodiorganosilanes with sodium metal, varying the Ph2SiCl2/Me2SiCl2 ratio was the chosen synthesis method. Products with different characteristics for solubility, structure (cyclic or linear), composition, and molecular weight distribution could be obtained depending on the comonomer ratios employed. The polysilane derivatives were characterized by infrared spectroscopy (IR), proton nuclear magnetic resonance (1H-NMR), and gel permeation chromatography (GPC). Valuable information related to the comonomers' reactivities was obtained, such as molecular weight distribution, composition, and relationships between yields of soluble, insoluble, and cyclic materials of each polycondensation reaction. © 1992 John Wiley & Sons, Inc.

    Synthesis and structure of crosslinked poly[(methylsiloxane)-co-(oxymethylene)] copolymers (1997)

    Notes: A series of new crosslinked copolymers was obtained by cationic ring-opening copolymerization of 1,3,5,7-tetramethylcyclotetrasiloxane and 1,3,5-trioxane. The poly[(methylsiloxane)-co-(oxymethylene)] copolymers are white crystals or glassy. Crosslinking reactions take place in the reaction medium. The degree of crosslinking increases with a higher concentration of the methylsiloxane units in the copolymers. The combination of solid-state magic-angle spinning nuclear magnetic resonance of 29Si and 13C and Fourier-transform infrared spectroscopy provided a quantitative description of the copolymer microstructure.
