Abstract: Disclosed is the use of an antiviral substance which, when given alone for 14 days, shows a mean initial suppression of viral load by 1.4 log or more and which does not reduce the number of lymphocytes, granulocytes and macrophages as determined by differential blood count after 12 weeks of treatment for the manufacture of a medicament for the immune system-assisted post-exposure prophylaxis of an HIV infection.

Abstract: A rubber composite comprising polyester fibers as the reinforcing material, wherein a compound having at least one cyclic imino ether group of a specific structure in its molecule is incorporated in a rubber composite except for adhesive-treated polyester cords.

Abstract: P. aeruginosa E87Ag antigen comprising polysaccharide fraction with molecular weight of about 27,000 which is contained in lipopolysaccharide of P. aeruginosa; anti-P. aeruginosa human or mouse monoclonal antibody which recognizes said E87Ag antigen; and mouse-human or mouse-mouse hybridoma which produces said monoclonal antibody.The monoclonal antibody can be used for making diagnosis and therapy of infections with P. aeruginosa.

Abstract: IgM derivatives into which acyl groups expressed by the following formula (I) are introduced to make their anticomplement activity weak by acylating the free amino groups existing in IgM up to 1-90% (acylation percentage)--COR (I)where R indicates an alkyl group having 1 to 4 carbon atoms, or a carboxylated alkyl group expressed by --(CH.sub.2)mCOOH (m is 2 or 3) or --CH.dbd.CHCOOH.These IgM derivatives can be used for making immunoglobulin preparations for intravenous injection use.

Abstract: Method of transfer printing for cellulosic textile articles by pretreating the article with a polyhydric alcohol, squeezing and drying the article, superposing the article with a transfer sheet printed with an ink containing a sublimable disperse dye and pressing the assembly under heating.

Abstract: Bacterial cells are separated from a culture broth by adding thereto a solution of casein or alkali-soluble soybean proteins, said culture broth being maintained at a pH less than 6. Bacteria cells are flocculated to form a protein-bacteria co-precipitate which is easily separable by a conventional procedure. The co-precipitate may be directly put to uses such as for foods or feeds.

Abstract: A method of transfer printing, wherein a release layer is formed on a temporary support; printing a pattern on said release layer with an ink containing coloring matter therein to obtain a transfer sheet; superposing an article to be transfer-printed on the printed surface of said transfer sheet; heating the superposed aggregate under pressure to transfer the release layer with the pattern onto said article to be transfer-printed; fixing the coloring matter to said article, and then soaping said article to remove the release layer, characterized in that the release layer consists of (1) 10-90 wt. percent of one or more thermoplastic polymers having excellent film-forming properties and water-solubility or alkaline water solubility as well as organic solvent solubility and (2) 90 to 10 wt. percent of one or more plasticizers having a melting point between 30.degree. and 120.degree.
