Abstract: The invention relates to the use of thromboembolic proteins. These contain, as their only structural portion effecting thrombolytic activity, the protease domain of human tissue type plasminogen activator. These derivatives show reduced side effects, such as a reduction in bleeding while demonstrating remarkable in vivo efficacy. The effect is surprising, given their in vitro properties.

Abstract: A method of treatment using carvedilol is disclosed, wherein the carvedilol decreases the mortality caused by congestive heart failure in patients. The patients are titrated with low amounts of carvedilol, with the initial titration dosage being only 10 to 30% of the daily maintenance dose.

Abstract: An apparatus for light transport measurements on a test object with a measuring head which includes a contact surface for placing against an interface of the test object, light irradiation device with a light transmitter for irradiating light through the contact surface and an interface into the test object, and detection device with a light receiver for detecting light leaving the test object. The contact surface comprises at least one optically transparent light passage point for the light, on which a large number of rigid light-conducting elements are arranged, wherein an optical connection with a light transmitter or light receiver assigned to a light passage point is produced by the whole of the light-conducting elements of the light passage site.

Abstract: A vector according to the invention with a positive selection possibility for cloning a DNA sequence into a host cell transformed with the vector, wherein the vector contains suitable restriction cleavage sites within a selection gene the functional expression of which is prevented by insertion of the foreign gene is characterized in that it contains a modified cap gene as the selection gene which codes for a CAP protein with modified DNA binding specificity the expression of which is lethal for adenylate-cyclase-positive host cells.

Abstract: The invention concerns human monoclonal antibodies of the IgG isotype against human pancreatic islet cells which can be obtained by immortalizing human lymphocytes of prediabetics or diabetics, treating the culture supernatant of the immortalized cells with a conjugate of antibodies against human Fc .gamma. and a label, subsequently treating with human immunoglobulin, incubating with immobilized human pancreatic islet cells identifying an immortalized human cell culture which produces an antibody against pancreatic islet cells via determination of the label bound to the immobilized islet cells, isolating a human immortalized cell which produces this antibody, propagating this immortalized cell and isolating the monoclonal antibody produced by these cells.The invention also concerns a process for the isolation of an islet cell antigen to which such antibodies bind as well as a method for the determination of antibodies against an islet cell antigen of the pancreas.

Abstract: The present invention concerns a method for the determination of an analyte in a sample liquid using a metal complex capable of luminescence as an analyte-specific marker group for the production of a measuring signal in which an unspecific metal complex is additionally added as an interference elimination reagent which has a structure that is chemically related to the marker group.

Abstract: Described herein is a method of promoting osteogenesis in a patient in need thereof by administering a plasminogen activator which activates the zymogen plasminogen by cleavage between arginine 506 and valine 561 to form the serine protease plasmin.

Abstract: An instrument for determining a characteristic of a biological fluid or a control comprises a radiation-reflective surface, a first source for irradiating the surface, a first detector for detecting radiation reflected from the surface, and a mechanism for determining the characteristic based on the detected radiation. A slide holds a sample of the biological fluid or control the characteristic of which is to be determined. The slide has two opposed walls transparent to the radiation. The first source and first detector are disposed adjacent a first one of the two opposed walls and the radiation reflective surface is disposed adjacent a second of the two opposed walls. A system is provided for supplying power and regulating supplied power from one of multiple power sources to the instrument.

Abstract: The invention concerns a process for improving the regeneration of oligodendrocytes, in particular of human oligodendrocytes, in which oligodendrocytes are treated in cell culture with nerve growth factor (NGF) or active fragments of NGF. Furthermore a composition is disclosed for treating diseases in which a demyelination of nerve fibres occurs which contains NGF or an active fragment thereof as the active substance, if desired, together with the usual pharmaceutical vehicles, auxiliary substances, fillers and diluents.

Abstract: The invention relates to monoclonal antibodies, humanized monoclonal antibodies and functional derivatives thereof specific for the platelet-derived growth factor receptor .beta.. Methods of use of the antibody, particularly in ameliorating restenosis, are also provided.

Abstract: System for determining the properties of tissue parts of a living organism, comprising an optoelectronic measuring device (10) and an attachment device (20) which is opaque to light and surrounds a measuring window (28) through which determinations are carried out. The device (20) has one or several components (26) for reproducibly attaching the measuring device (10) in a direction toward a first surface of the tissue. Other subject matters of the invention are an attachment device (20) and a method for determining the properties of tissue parts with the aid of the claimed system.

Abstract: A method and apparatus for the quantitative analysis of sample liquids. A sample is dried and irradiated with visible and/or infrared light. Light that is diffusely or specularly reflected from the sample and sample carrier is detected. and analysed.

Abstract: The invention concerns interference-eliminating agents for avoiding unspecific interactions in immunoassays in which avidin or streptavidin or a derivative thereof are used as the interference-eliminating agents.

Abstract: Packaging system for liquid reagents in which two or more vessels with holding areas are combined by pressing a plug-on plate onto the holding areas of the vessels. For this purpose the plug-on plate has two or more apertures the cross-section of which essentially corresponds to the cross-section of the holding areas of the vessels. Plug-on plate and/or holding areas of the vessels can have stop elements which, after the combination, hinder the separation vessels and plug-on plate.

Abstract: A systems for test elements used for clinical chemical analyses has several test elements, each of which is individually sealed to be impermeable to water vapor. The method provides for the removal of test elements and protects the test elements contained in it against effects from the outside.

Abstract: The invention concerns a method for the simultaneous colorimetric and electrochemical measurement of an analyte using an oxidizing enzyme and a chromogen A that accepts electrons from the enzyme which is characterized in that the chromogen A after reduction to A' reacts by coupling to a substance BX to form a colored substance A'B the concentratin of which is measured colorimetrically as a measure for the presence or amount of the analyte and in that an electrochemically measurable group X.sup.- is cleaved off during the coupling reaction the concentration of which is measured electrochemically as a measure for the amount of the analyte.
