Abstract: The invention relates to a method for producing hyperbranched amylopectin having a mean molecular weight ranging between 2,000 and 29,000 Dalton and an average degree of branching of more than 10 percent and less than 20 percent, said degree of branching being expressed in mole percent of the anhydroglucose units carrying branching points. According to the inventive method, the molecular weight of plant amylopectins or starch rich in amylopectin is reduced to molecular weights not exceeding 60,000 Dalton by means of a-amylase or acid hydrolysis in a first hydrolysis step, and the molecular weight of the reduced product obtained in the first hydrolysis step is further reduced by means of ?-amylase reduction in a second hydrolysis step. The invention further relates to the production of coupling products of the hyperbranched amylopectin with a pharmaceutical agent.

Abstract: The invention relates to novel pharmaceutical forms for antibiotics containing amino sugar, amphotericin B, daunorubicin and doxorubicin, in which the known side effects are reduced and which can be used in a simple manner. The antimycotic agent B is nephrotoxic. The cytostatic agents daunorubicin and doxorubicin are highly cardiotoxic. The novel pharmaceutical forms are antibiotic-starch conjugates, wherein the antibiotic is combined with the polysaccharide at the reducing end thereof by means of a peptide bond. According to the invention, said bond is carried out by means of J2 oxidation of the starch derivative at the reducing end thereof in an aqueous alkaline solution, and by coupling the starch derivative oxidised thereby to the antibiotic in an organic solution. The conjugates obtained are less toxic. The polysaccharide part can be decomposed by serum-?-amylase and the peptide bond can be accessed by an enzymatic attack.

Abstract: The invention relates to the use of hyperbranched amylopectin which has an average branch degree of between >10 and 25 mol % and a molecular weight (Mw) ranging from 40.000-800.000 Dalton and the derivatives thereof in methods for surgical or therapeutic treatment of human or animal bodies or in a diagnostic method, preferably as a plasma volume expander. Plasma volume expanders based on hydroxy-ethylated amylopectin have, as a result of hydroxy ethylation, hitherto exhibited the disadvantage of incomplete metabolism and thus temporary tissue storage which is linked to side-effects. According to the invention, novel plasma expanders based on polysaccharides which do not exhibit the same disadvantages as the former are provided.

Abstract: To produce a two-chamber arrangement having a first chamber, which is filled with a first component, and a second chamber, which is filled with a second component, two separate bags are sterilized and filled independently of each other with the first/second component. Only after the bags have been sterilized and filled are they connected to each other in such a way that the component contained in one chamber can be transferred into the other chamber so as to be able to mix the two components together. Once they have been filled, the first and second bags are preferably sealed with an openable peel seam, after which the bag ends are welded together.

Abstract: The present invention relates to dialysis solutions for peritoneal dialysis, containing hydroxyethyl starch as the osmotically-active substance, electrolytes and, optionally, conventional additives, where the hydroxyethyl starch has a molecular weight Mw in the range from 10,000 to 150,000, a substitution MS in the range from 0.10 to 0.40, a substitution DS in the range from 0.09 to 0.35 and a substitution ratio C2/C6≧8. With this peritoneal dialysis solution it is possible, with an outstanding ultrafiltration, to maintain a longer dwell time, for example the dialysis solution can be utilized for a period of 12 hours in the CAPD without replacement. In addition, the inventive dialysis solution is also particularly advantageous for patients with residual kidney function. The resorption of the osmotically active substance is clearly diminished and even after a dwell time of 12 hours it amounts to a maximum of 60-70%.
