Abstract: Animal cells are described which can be infected by influenza viruses and which are adapted to growth in suspension in serum-free medium. Processes for the replication of influenza viruses in cell culture using these cells are furthermore described, as well as vaccines which contain the influenza viruses obtainable by the process or constituents thereof.

Abstract: Novel processes for the replication of influenza viruses in cell culture, and vaccines and diagnostic compositions which contain the influenza viruses obtainable by the process or constituents thereof, are described.

Abstract: A modified C1 esterase inhibitor is described which on the one hand binds to the surface of HIV, but on the other hand not to human cell membranes. This modified C1 esterase inhibitor can be used in vivo and in vitro for blocking the infectiousness of HIV.

Abstract: The invention relates to the removal of viruses from aqueous solutions, as a rule protein solutions, by ultrafiltration. This entails the viruses to be removed being increased in size by incubation with a high molecular weight receptor binding thereto, preferably a specific antibody, so that, on the one hand, the separation effect is improved and, on the other hand, a larger pore diameter which can now be chosen for the filters used also makes it possible for smaller viruses to be separated from larger protein molecules present in protein solutions, and, where appropriate, the filtration rate is increased.

Abstract: A process and an agent for the sanitization of tissues or cell cultures and also of materials and equipment which can be contaminated with viruses are described. For sanitization, a solution of a substituted phenol or of a substituted phenol ether is employed here which as substituents carries one or two saturated or unsaturated hydrocarbon radicals which in each case can have up to 4 carbon atoms.

Abstract: A process for separating HIV from a fluid is described, in which the HIV is bound to a C1 esterase inhibitor immobilized on a support material. The process can be carried out both for the preparation of HIV-free blood donations and therapeutically for the reduction of the virus load in the blood by means of a blood lavage under the conditions of an extracorporeal blood circulation. The C1 esterase inhibitor can be bonded to a support material which is customary in affinity chromatography or to the fibers of a filter.

Abstract: A permanent cell line PH2, and a process for replication of rabies viruses which have a cytopathic effect (CPE) is claimed. The process comprises: infecting the PH2 cell line with the virus to be replicated; incubating the cells; and isolating and purifying virus particles after they have reached a sufficiently high titer.

Abstract: The invention relates to a pharmacological composition comprising a polyelectrolyte complex, in particular a polyacid with an average particle size of less than 15 .mu.m and an active agent, among which are active peptides, proteins, enzymes, enzyme inhibitors, antigens, cytostatics, antiinflamatory agents, antibiotics and vaccines. The said composition ensures that the active agent is converted in a non-deleterious manner into a form which can be administered. In addition, the biodistribution, bioavailability and absorption of the pharmaceutical are beneficially affected.

Abstract: The invention relates to a process for growing Cydia pomonella granulosis virus (CpGV), which comprises propagating the virus in Larvae of Tortricidae species which have a LD.sub.50 for this virus which is a factor of 5 to 100,000 higher than that of codling moth Larvae.
