DEXTRAN REDUCED IN BORON CONTENT, PROCESS FOR PRODUCING THE SAME, AND DEXTRAN PACKED IN CONTAINER IN SOLUTION STATE

摘要

The present invention relates to dextran whose boron content is reduced to a value less than 0.30 .mu.g/g (dry basis) calculated on the basis of boron atom, a process for producing the same, and dextran with which a container is filled in a solution state. Dextran of the present invention is obtained by treating a boron-containing dextran with a lower alcohol, and said dextran has such a characteristic that deposition is inhibited or the deposition rate is drastically reduced when using it in the form of a solution. Therefore, an isotonic sodium chloride solution of said dextran is suitably used as substitute plasma or external perfusate in an operation.
