Abstract
SO far as we are aware, no measurements relating to the stability of clinical dextran solutions kept for several years have been published. Two dextran solutions made in the United States, A and B, and two made in Great Britain, C and D, were examined in 1954, and again after storage for 5 yr. at 4° C. Where applicable the methods of testing described in the British Pharmacopœia1 were used. The optical rotation of each dextran was determined and used in calculating the concentrations of solutions for the viscosity measurements (Table 1). Dextran D had undergone the most change; the changes in the others were relatively small.
