摘要:
A process for purifying and collecting albumin from plasma and plasma fractions involves diafiltration of an albumin-containing plasma fraction; stabilizing the resulting albumin fraction with sodium chloride and an amino acid in the absence of any added fatty acid; pasteurizing the stabilized albumin fraction; and diafiltering the pasteurized fraction to remove, along other things, stabilizers. In one embodiment, the amino acid stabilizing agent is acetyl tryptophan. The resulting albumin has at least about 80% albumin binding capacity relative to natural plasma albumin, and is storage stable for about 30 months at 30° C.
摘要:
Composition of biocompatible microparticles of alginic acid for the controlled release of active ingredients by intravenous administration. The invention relates to a biocompatible composition which comprises microparticles of alginic acid or its salts and an active ingredient. More particularly, the invention relates to microparticles for the encapsulation of an active ingredient to be administered intravenously to a patient who needs it. These microparticles are of a combination of size sufficient to increase the half-life or survival of the active ingredient in blood, with a low uptake in the liver and a fast cell clearance when administered intravenously.
摘要:
A device for the application of two components of fibrin adhesive at a treatment site comprising a support for syringes comprising two parallel cylindrical housings to receive corresponding syringes and a plunger connecting member, characterised in that the said syringe support comprises a passage for insertion of the said plunger connecting member, the said passage being located in the space defined between the cylindrical housings of the said syringe support, the said plunger connector having a zone with a suitable geometry to slide within the said passage and in that the transverse cross-section of the said passage of the syringe support has a maximum opening at the ends and a minimum opening in the central part.
摘要:
The invention comprises taking colour pictures of back-lighted analysis microtubes and using the colour information in the images to identify areas of the image which are relevant for interpreting the result of other possible artefacts, as well as detecting abnormal samples and/or reactions characterised by changes in the colour properties of the reaction.
摘要:
The apparatus comprises a single transportable structure provided with several separate compartments located in a vertical stack within a cabinet, with means for the vertical transport of gel cards, means for the transport of units for moving the cards and pipetting probes, being displaceable to the entire transverse cross-section of the compartments in at least two of the vertical compartments or floors through moving along coordinate axes X, Y, Z at right-angles, and control means so that automatic functioning can take place simultaneously with manual actions to load and unload the necessary materials (samples, reagents, cards, wash solutions and waste solutions) in a random manner.
摘要:
The process is characterised by the preparation of a solution of Von Willebrand Factor or a complex of Factor VIII/Von Willebrand Factor which contains VWF and a concentration of up to 12 IU VWF:RCo/ml and a Von Willebrand Factor/Factor VIII ratio of 0.4 or more; and then proceeding with nanofiltration of the solution prepared in a) through a filter having a pore size of less than 35 nanometres.
摘要:
The invention discloses a purified albumin solution of human origin with low prekallicrein activator (PKA) activity and stability over time characterised in that it has an antithrombin content equal to or greater than 0.03 mg/g of albumin, and a process for production thereof by the partial extraction of the antithrombin during fractionation of the human plasma.
摘要:
The invention is based on feeding the closed bodies to be evaluated to a station for the application of high voltage for the formation of the arc across the inner space of the body and capturing the arc formed by means of a CCD camera which will compare, adjustably, the luminous intensity of the arc created within the body subjected to checking with a threshold value determining whether the luminous intensity is above or below the threshold, which will be the rejection threshold, rejecting the bodies which do not comply with the predetermined threshold value, separating them from the whole of the accepted bodies.
