Abstract: An intravenously administrable polyclonal immunoglobulin preparation for the treatment and prophylaxis of bacterial infections containing at least 50% by weight of IgM in terms of the total content of immunoglobulin, exhibiting a low anticomplementary activity, being stable in aqueous solution, and being free of viruses. It can also consist of or also contain a mixture of several monoclonal IgM antibodies. The source material for its manufacture is an immunoglobulin-containing fraction of human, animal, or bacterial provenance. The fraction is treated with an anion exchanger that is eluted with a saline or pH gradient and the eluate is optionally subjected to gel filtration, treated before or after the chromatography with .beta.-propiolactone and PEG 4000, and optionally heated. Treatment with .beta.-propiolactone and ultraviolet light, treatment with solvents and detergents, or pasteurization can also be conducted. Proteins, sugars, or mixtures of amino acids are optionally added to the preparation.
Abstract: The invention is directed to the administration of Interleukin 6 for the purpose of enhancing endogenous erythropoietin levels in vitro and in vivo. The invention further encompasses methods of treatment of disorders characterized by, or including, erythropoietin deficiency. Such disorders include the anemias of chronic inflammation, renal failure, AIDS, and malignancy.
Abstract: Pharmaceutical formulations for the treatment of diabetes mellitus are disclosed, wherein the pharmaceutical formulations contain at least one insulin derivative modified with a base in position B31 of the insulin B chain and having an isoelectric point between 5.8 and 8.5 and/or at least one of its physiologically tolerated salts in a pharmaceutically acceptable excipient and a relatively high zinc ion content in the range from above 1 .mu.g to about 200 .mu.g of zinc/IU. The preferred insulin derivative modified with a base for this pharmaceutical formulation is human insulin-B31-Arg-OH and human insulin-B31-Arg-B32-Arg-OH. The formulation is used for the treatment of diabetes mellitus; it has a particularly favorable action profile.

Abstract: A substantially heme-free blood protein product is produced by adding an acid to a blood cell suspension to a low pH to disrupt erythrocytes present in the suspension thereby releasing hemoglobin, and to cleave off the heme moiety from the major proportion of the hemoglobin. The released heme forms a precipitate which is removed by centrifugation. Heme moieties remaining in the blood protein solution are degraded by treatment with an oxidizing agent, e.g. hydrogen peroxide. The product has a content of sulfur-containing amino acids which corresponds to the content thereof in natural hemoglobin, as well as foaming and emulsifying properties corresponding to naural hemoglobin. The product has a high lysine content and may be used to enrich the protein content of edible products, e.g. cereals, or to replace part of the meat in meat products. An edible product containing up to about 25% by weight of blood plasma mixed with the product is also disclosed.

Abstract: Compositions and methods for their use in modulating animal cellular responses are disclosed. The compositions include as an active agent an effective amount of an 8-substitued guanine derivative bonded 9-1' to an aldose having 5 or 6 carbon atoms in the aldose chain. The composition includes a diluent amount of a physiologically tolerable carrier. The guanine derivative is free of electrically charged functioinality, while the 8-substituent has an electron withdrawing inductive effect greater than that of hydrogen and contains fewer than about 15 atoms. Animal cellular responses are modulated by contacting the cells with a composition of this invention.

Abstract: A method for inhibiting production of IgE, and a method for enhancing production of IgG are taught. The methods are linked to the role of interleukin 9 in antibody production. Specifically, production of IgG is potentiated by administering either to a subject or a cell culture a combination of interleukin 4 and interleukin 9. Production of IgE is inhibited by administering an amount of an interleukin 9 inhibitor to a subject.

Abstract: A method for purifying hemoglobin, mixed with other proteins is described, wherein the mixture is contacted with an ion exchange matrix so that the hemoglobin is adsorbed to it. The matrix is washed to remove unadsorbed components, and the hemoglobin is then selectively eluted using a ligand which specifically binds the hemoglobin causing it to desorb from the matrix. The method can also be used to effect reduction of methemoglobin to hemoglobin on an ion exchange matrix followed by selective elution to achieve purification. The method can also be used to purify methemoglobin.
Abstract: A source for antibodies (both IgG and IgM types) is put into an aqueous solution which includes a virucidal agent under conditions sufficient to assure substantially complete dissolution of both the antibodies and the virucidal agent and virus inactivation. Then the pH, conductivity and antibody concentration of the solution are then changed to obtain conditions sufficient to assure the precipitation of substantially all antibodies while maintaining substantially all of the virucidal agent in the supernatant solution.In preferred embodiments, using a TNBP/TWEEN virucidal agent, the original solution conductivity ranges from about 0.03 to 0.20 M MHO/CM, the pH ranges from about 4.75 to 4.85, and the protein concentration, when measured at A280, ranges from a reading of about 5 to 40. In the second precipitation step, the pH is changed to a range of about 6.0 to 7.5 and the conductivity is changed to a range of about 0.05 to 0.
