Surgical dressings with improved consistency: Surgical dressings with improved consistency. (Lion Corp., Japan). Jpn. Kokai Tokkyo Koho JP 59013718 A2 24 Jan 1984 Showa, 4 pp. (Japanese). (Japan). CODEN: JKXXAF. CLASS: IC: A61K009-70; A61F007-02. APPLICATION: JP 82-123243 14 Jul 1982. DOCUMENT TYPE: Patent CA Section: 63 (Pharmaceuticals) Surgical dressings, that maintain moisture for a prolonged period and firmly adhere to the skin, contain gelatin, acrylic acid polymer [9003-01-4] or a mixt. of polyacrylate alkali salt and acrylic acid polymer, 2,3-dialdehydo starch [9047-50-1], and hardly sol. metal salts or metal oxides. Thus, 18% gelatin 20, Na polyacrylate [9003-04-7] 2, poly(vinyl alc.) 1, CM cellulose 2, gum acacia 2, a 20% acrylic acid polymer aq. soln. 25, glycerin 15, kaolin 5, and water 9.8 parts were mixed at 40°, and to this was added a 10% 2,3-dialdehydo starch soln. 3 parts and a mixt. of Me salicylate 1, dl-camphor 0.8, l-menthol 1, vitamin E 0.5, and polysorbate-80 0.5 parts. Finally, 1.4 part CaCO3 suspended in 10 parts H2O was added to obtain a surgical dressing.Except for chemicals metioned above, 813-94-5 and 9003-04-7 are also used. .

Altering the chemical and functional properties of protein fibers by reaction with carbonyl compounds: Altering the chemical and functional properties of protein fibers by reaction with carbonyl compounds. I. Lysine blocking and modification of shear strength. Schmandke, H.; Hartmann, B. (Zentralinst. Ernaehr., DAW, Potsdam-Rehbruecke, E. Ger.). Nahrung, 21(3), 215-18 (German) 1977. CODEN: NAHRAR. DOCUMENT TYPE: Journal CA Section: 17 (Foods) The shear strength of spun broad bean-casein (1:1) fibers increases by reaction with aldehydes in the sequence glyoxal [107-22-2], dialdehyde starch [9047-50-1], H2CO [50-00-0], and glutardialdehyde [111-30-8]; this increase depends on the aldehyde concn. 107-22-2 and 111-30-8 which are cas registry numbers of substances are two of reagents here. and is linear. Lysine [56-87-1] blocking increases in the sequence glyocal, H2CO, dialdehyde starch, glutardialdehyde, and approaches a limiting state. .
