    • A buffered body fluid expander solution, in which the buffer is a physiologically acceptable buffer that is not an inorganic phosphate buffer, comprises calcium ions and magnesium ions at a concentration ratio of 5:1 to 1:1. The non-phosphate buffer may be a physiologically acceptable N-substituted aminosulfonic acid buffers, especially those having a pKa value in aqueous solution of from 7.1 to 7.5 at 2O0C, and most preferably N-tris(hydroxymethyl) methyl-2-aminoethanesulfonic acid (TES), 3-(N-morpholino) propanesulfonic acid (MOPS), N,N-bis (2-hydroxyethyl)-2-aminoethanesulfonic acid (BES) and combinations thereof. Preferred components include from 100 to 150 (preferably about 135) mmoles/L sodium ions, from 2.5 to 6.2 (preferably about 5) mmoles/L potassium ions, from 0.1 to 2.5 (preferably about 1.25) mmoles/L calcium ions, from 0.4 to 25.0 (preferably about 0.45) mmoles/L magnesium ions, from 96 to 126 (preferably about 118) mmoles/L chloride ions, 2 to 11 mmoles/L (preferably about 10) glucose (preferably D-glucose), from 50 to 150 (preferably about 110) μmoles/L glycerol, from 7 to 15 (preferably about 10) μmoles/L choline, from 5 to 400 (preferably about 300) μmoles/L glutamate (preferably L-glutamate), from 5 to 200 (preferably about 20) μmoles/L aspartate (preferably L-aspartate), from 100 to 2000 (preferably about 400) μmoles/L glutamine (preferably L-glutamine), from 15 to 215 (preferably about 60) μmoles/L pyroglutamate, from 20 to 200 (preferably about 100) μmoles/L arginine (preferably L-arginine), from 1 to 120 (preferably about 40) nmoles/L thiamine pyrophosphate (TPP), from 40 to 70 (preferably about 50) μmoles/L D- or DL or L-carnitine (preferably L-carnitine), and from 5 to 200 (preferably about 28) ml.U./L porcine or human insulin (preferably human insulin). The solutions are useful for the manufacture of medicaments and blood volume expanders, for treating hypovolemia or for treating the loss of extracellular and interstitial fluid in subjects suffering with burns, for treating respiratory and/or metabolic acidosis in a subject, for perfusion of the abdominal cavity during peritoneal dialysis of a subject with acute renal failure or an acute toxicity condition, for preventing and/or ameliorating reperfusion injury, and for delivering a therapeutic, test and/or synergistic agent to a subject, including a biological agent, such as at least one stem cell, peptide or genomic derived protein.

    • The invention relates to a method for producing an aqueous albumin solution from an albumin parent solution containing stabilizer molecules capable of occupying binding sites of the albumin. In order to increase the albumin binding capacity for other molecules, at least a portion of the stabilizer molecules are removed from the albumin of the albumin parent solution and separated out from the albumin parent solution. In order to provide a method of this type, with which a stabilized commercial albumin parent solution can be prepared, in comparison to the prior art, easier, faster, and more economically and to prepare albumin without altering it while removing a large portion of the stabilizers and while increasing the albumin binding capacity, the method comprises the steps in which the albumin parent solution is brought into contact with a solid adsorber material whose affinity to at least a portion, preferably to all of the stabilizer molecules used, is higher than the affinity of the albumin to the corresponding stabilizer molecules, and the albumin solution is separated out from the adsorber material, the method being carried out at a pH value > 3.
