An attempt was made to evaluate experimentally the importance of surface charge characteristics of tumour cells for growth of subcutaneous transplants and for metastasis distribution and growth in a syngeneic tumour-host system (MCG1-SS in CBA mice). The

DEXTRANS, a mixture of glucose polymers of various size and geometry, were introduced into medicine in the early 1950's by the Swedish scientists, after a long search for a practical nontoxic plasma substitute. 1 As a byproduct of this search, it was soon found that the high fractions of dextrans produced erythrocyte aggregation, impaired ...

Methods currently available for the examination of the retinal vasculature of laboratory animals have significant drawbacks. Fluorescein angiography of rodent eyes is hampered by a poor view of the peripheral retina and difficulty in performing fundus ...

Static compression is associated with decreased diffusivity of dextrans in cartilage explants.
Archives of Biochemistry and Biophysics, 2000The chondrocytes of adult articular cartilage rely upon transport phenomena within their avascular extracellular matrix for many biological activities.

Hyperfiltration precedes renal function loss in several nephropathies. Animal studies suggest this may be due to accompanying increases in transglomerular capillary hydrostatic pressure difference (delta P) and/or altered glomerular processing of ...

Publisher Summary This chapter discusses dextrans of commercial interest and in particular, the dextran from Leuconostoc mesenteroides NRRL B-512(F). Dextran is produced in most developed countries, primarily for clinical products. Good yields of native dextran are dependent on vigorous growth of the organism, optimal elaboration of the enzyme, and ...

Surface activity and emulsification properties of hydrophobically modified dextrans.
Journal of Colloid and Interface Science, 2002Neutral polymeric surfactants were synthesized by covalent attachment of hydrophobic groups (aromatic rings) onto a polysaccharide backbone (dextran). By changing the conditions of the modification reaction, the number of grafted hydrophobic groups per ...

Studies on dextran and dextran derivatives. II. Acid hydrolysis of native dextran
Biopolymers, 1964AbstractThe kinetics of the depolymerization of native dextran in dilute hydrochloric acid at different temperatures has been followed by measurements of M̄w, M̄n, [η], 〈ρ2〉1/2, and S. The data allow the correlation of the various parameters of the total hydrolyzate at various degrees of depolymerization. At a first approximation the results conform to

Molecular weight dependent tissue accumulation of dextrans: in vivo studies in rats.
Journal of Pharmacy and Science, 1994The effects of molecular weight (M(r)) on the serum and urine pharmacokinetics and tissue distribution of dextrans, potential macromolecular carriers for drug delivery, were studied in rats.
