Abstract: The present invention relates to immobilized pepsin for use in removing immune complex which comprises pepsin fixed on a suitable carrier, and to a process for removing immune complex which comprises bringing blood or plasma from a patient suffering from an immune complex disease, such as rheumatoid arthritis and systemic erythematosus, into contact with the immobilized pepsin.

Abstract: This invention provides a human leucocyte pepsin-like enzyme and a therapeutic agent and method for treating allergic disorders, immune complex diseases and tumors, the agent containing the enzyme as an effective ingredient. The human leucocyte pepsin-like enzyme of this invention is a protein of human origin and, therefore, a therapeutic agent containing said enzyme as an effective ingredient shows extremely little adverse reactions such as anaphylaxis and thus is highly safe.

Abstract: A therapeutic agent for the treatment of cardiovascular diseases which contains as the effective component at least one compound selected from the group consisting of 5-hydroxydecanoic acid, a salt thereof, an ester thereof and .delta.-decalactone, which is a lactone of 5-hydroxydecanoic acid.

Abstract: Therapeutic agent for the treatment of allergic disorders, immune complex diseases and tumors, which contains a human urinary acid protease as an active ingredient, and a method for treating allergic disorders, immune complex diseases and tumors by administering the said acid protease, which has never been used as a therapeutic agent for allergic disorders, immune complex diseases and tumors. Since the acid protease is a protein of human origin, the probability of adverse reactions such as anaphylactic shock due to the antigenicity of the acid protease is believed to be extremely small.

Abstract: Target Cell Lysis Factor (TCLF) is produced by exposing a human cell line capable of producing TCLF to a TCLF inducer to induce TCLF production, and collecting and purifying the accumulated TCLF. The TCLF which is produced includes lymphotoxin and human Tumor Necrosis Factor (hTNF). The hTNF may be separated and purified. The human cell lines are preferably human leucocyte and human lymphoblastoid lines, such as BALL-1, TALL-1, NALL-1 Namalwa, MOLT-3, Mono-1, M-7002, B-7101, JBL, EBV-Sa, EBV-Wa, EBV-HO, BALM 2, CCRF-CEM, DND-41 and CCRF-SB, as well as human cell lines which are obtainable by transforming normal human monocytes, or granulocytes. All of these human cell lines are multipliable by implanting them in a non-human warm-blooded animal, or alternatively, allowing them to multiply in a conventional-type diffusion chamber by which the nutrient body fluid of a non-human warm-blooded animal is supplied to them.

Abstract: A method of producing .gamma.-globulin which can be administered intravenously without adverse reactions and loss of opsonic activity is provided. The method comprises treating .gamma.-globulin with pepsin or uropepsin in a neutral pH range of 6.0 to 7.5. The aggregates in .gamma.-globulin are selectively decomposed by the method of the present invention, while any decomposition of monomer .gamma.-globulin molecule is substantially prevented. A therapeutic agent for intravenous injection which is reduced its anticomplementary activity and is stabilized by adding uropepsin which serves simultaneously as a proteolytic enzyme and a stabilizer, to human .gamma.-globulin. Uropepsinogen can be also as a stabilizer.
