Sažetak

Physicochemical characterization of clinical dextran samples
of Yugoslav ·production was made and the results were compared
with the specifications of clinical dextrans produced in other
co untries. Measurements of .optical rotation, density, viscosity
a nd light scattering were undertaken, and the kinetics of the
a lkaline iodine oxidation was analysed. The experiments were
performed on unfractionated clinical samples and both low and
high 100/o fractions . For the purposes of routin_e determinations of
molecular weight a relation between 1['P] and Mw was given. It is
valid for unfractionated clinical samples. produced in the same way
and having Mw in the range from 65,000 to 95,00Q. From our data it
could be concluded that Yugoslav clinical dextran belongs to tbe
group of clinical dextrans with lower mol ecular weight (Swedish
a nd U. S. dextran) ..
