Filed: 1981-06-26
Abstract: PURPOSE:To produce a polyurethane excellent in selective permeability and antithrombotic property, by addition-polymerizing a linear or cyclic dimer of a hydroxy group-containing alpha-amino acid with a diisocyanate. CONSTITUTION:A polyurethane having a linear dipeptide-doil as one component is synthesized by condensing a hydroxyl group-containing alpha-amino acid to form  a dipeptide-diol and addition-polymerizing the dipeptide-diol with an aliphatic or aromatic diisocyanate in the presence or absence of an alkylenediol as a chain extender. Or, a polyurethane having a cyclic dipeptide as one component is synthesized by cyclocondensing an alpha-amino acid having a hydroxy group in the side chain to form a cyclic dipeptide-diol and reacting this in the manner as in above. The obtained polyurethane can be applicable to medical devices and appliances  of which an antithrombotic property is required (e.g., blood vessel catheter, shunt, extracorporeal circulation circuit, blood pump for artificial hearts) and,  because it has a selective adsorptive permeability for metal ions, amino acids,  surgars, etc., it can further be applicable to dialysis membranes of artificial  kidneys.

Title: Latex reagent

IPC: A61K39/00
Filed: 1982-06-10
Abstract: PURPOSE:To obtain a latex reagent for detecting toxins, by fractionating immunoglobulin (IgG) from antiserum against intestinal bacterial toxins, and sensitizing latex particles to IgG. CONSTITUTION:Solid and watery feces from patients of pseudomembranous enteritis are extracted with 0.9% NaCl on solution, and the extract is used as a clindical sample. When IgG the surfaces of latex particles and toxins D-1 and D-2 in the said extract are allowed to be reacted with each other to assay the said toxins, the toxins in patients of enteritis are semiquantitatively detected by observing macroscopically the extent of the aggregation messes of latex on a slide glass by means of a multivalent antibody reaction. Owing to rapidity of the above procedure, judgement of pseudomembranous enteritis caused by Clostridium diflicile is made much more rapidly with higher accuracy in comparison with conventional procedures. When the aggregation reaction of the latex reagent with the toxins in feces from the patients diagnosed with this procedure is compared with the reaction of extract of feces from normal human, the toxins are clearly detected according to the existence of the aggregation masses of the latex reagent, and thus the judgement of pseudomembranous enteritis can be made in the manner clinical examination.
