Determination of Molecular Weights of Dextrans by Means of Alkaline Copper Reagents
Reducing values were determined for samples of clinical dextrans, gentiobiose, and isomaltose with several alkaline copper reagents. The results for t he dextrans were converted to number-average molecular weights on the assumption th a t eq uimolecular quantities of dextran , isomaltose, and gentiobiose have approximately the same reducing power . The molecular weights, t hus obtained , are in...
متن کاملCurrent status of renal clearances.
Determination of renal clearances continues to have value in clinical situations. Current knowledge of renal function permits expansion of the clearance concept to include non-excretory mechanisms by which kidneys clear substances from blood. Measurement of clearances is useful in quantifying renal function, progression of renal disease, response to therapy, determining the amount of dialysis r...
متن کاملRenal Clearances of Grass Polysaccharide: Observa- Tions
Dr. D. J. Bell, Biochemical Laboratory, Cambridge, drew our attention in 1948 to a fructosan polysaccharide (levan) prepared from Italian rye grass. It is readily soluble in cold water, yields levulose on acid hydrolysis and is not metabolized. At that time, the fructosan was believed to be a homogeneous substance with a molecular weight somewhat greater than that of inulin, so that the suggest...
متن کاملInulin and Endogenous Amino Acid Renal Clearances
Cystinuria is manifested by cystine calculi and high urinary excretion of cystine (2), lysine, arginine (3), and ornithine (4). Abnormally low plasma levels have been established for cystine (5, 6), lysine (7), arginine, and ornithine (5, 8). Several investigators have previously demonstrated increased renal clearances for cystine, lysine, arginine, and ornithine (7-11). These four amino acids ...
متن کاملAlbumin and creatinine clearances in renal disease.
1. The ratio of albumin clearance to creatinine clearance (CJC,) was determined on 129 occasions in forty patients with a wide variety of renal diseases, both 24 hcollections of urine and random mid-morning samples being used. The clearance ratios derived from 24 h urine (24 h C,/C,-J and random urine (R C,/C,-J were compared with random urine protein concentration, 24 h urine protein excretion...
