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

摘要

A dextrain having a boron content reduced to below 0.30 .mu.g/g in terms of boron atom (in a dried state); a process for producing the same; and the dextran which is in a solution state and contained in a container. This dextran is obtained by treating a boron-rich dextran with a lower alcohol. The dextran is characterized by being inhibited from precipitating when used in a solution state, or by being significantly reduced in precipitation rate. Since, therefore, a solution of this dextran in, for example, physiological saline as a high storage stability, it is suitable for use as a plasma expander or an extracorporeal circulatory fluid for operations, etc.
