Abstract: Human urine trypsin inhibitor is provided as an agent for treating acquired immunodeficiency syndrome (AIDS), preventing the infection with AIDS or preventing the onset of AIDS after such infection. It can be administered intravenously for the treatment and externally for the prevention.
Abstract: A modified superoxide dismutase represented by the formula: ##STR1## (wherein R is as defined below; SOD is a residue of superoxide dismutase) is produced, in a shortened period of reaction with a high and constant modification ratio, by reacting a polymeric carbonyldiimidazole derivative represented by the formula: ##STR2## (wherein R is a residue of a water soluble polymer having an average molecular weight of about 2,000 to 10,000) with superoxide dismutase in the presence of a buffer having a pH of 9.0 to 11.0 and a concentration of 0.1 M to 0.5 M, preferably 0.2 M to 0.4 M, at a temperature of 30.degree. to 70.degree. C., preferably 45.degree. to 60.degree. C. The modified superoxide dismutase thus produced exhibits a suitably prolonged blood half-life.
Abstract: Secretory immunoglobulin A preparations substantially not containing virus are produced by a process wherein secretory immunoglobulin A which might be contaminated with viruses is (1) heated about 60.degree. C. for about 10 hours, or (2) subjected to the reaction with tri-n-butyl phosphate and a surfactant and the heating as mentioned above, as liquidized form in an aqueous medium, and then polymerized matters are precipitated from the resulting solution by adding polyethyleneglycol thereto.

Abstract: There are provided thrombolytic agents suited for oral administration. The agent comprises a proteolytic enzyme of subtilisin family, such as subtilisin BPN', subtilisin Carsberg, subtilisin amylosacchariticus, etc., produced by microorganisms belonging to genus Bacillus, such as Bacillus subtilis, Bacillus licheniformis, Bacillus amyloliquefaciens, etc. and, even when administered orally, exhibits thrombolytic activity.
Abstract: LEM which is an aqueous extract of a mycelial culture of Lentinus Edodes and has a sugar composition composed of arabinose, xylose, glucose, mannose, galasctose, fucose and rhamnose, as well as a fraction of LEM which corresponds to molecular weights of 10,000 to 1,000,000 daltons and has a sugar composition composed of arabinose, xylose, glucose, mannose and galactose are provided as agents for inhibiting the adsorption of herpesviruses such as herpes simplex to the cells.
Abstract: An inhibitor of the proliferation of herpesviruses and of the recurrence of affections caused by their latent infection, which is an active material obtained by fractional purification of the aqueous extract from cultured Lentinus edodes mycelia.
Abstract: Antiserum which can recognize all subtypes of human leukocyte interferon is prepared from the blood of an animal immunized with partially purified human leukocyte interferon obtained from a culture of human leukocyte stimulated with Sendai virus.The antiserum is added to a column whereon concentrated culture broth of human leukocyte has been immobilized to adsorb impurities, the effluent is added to a column whereon partially purified human leukocyte interferon has been immobilized to adsorb anti-human leukocyte interferon antibody and then the antibody is eluted from the column.The antibody thus obtained recognizes all subtypes of human leukocyte interferon and can be separated by a chromatography to each monoclonal antibody which recognizes a single subtype.Employing these antibodies, the subtypes of human leukocyte interferon or their antibodies in a sample can be analized or assayed.
