THE RENAL CLEARANCE OF ALKALI-STABLE INULIN

Open access
Walser, Mackenzie, Davidson, Douglas G., Orloff, Jack·1955·Journal of Clinical Investigation

Abstract

Commercial inulin available at present is not a homogeneous product (1). It consists of two major fractions the proportions of which vary: (a) a portion of relatively large molecular weight resistant to heating in alkali; and (b) a portion of smaller molecular weight susceptible to destruc-tion with alkali. In addition, most samples con-tain a small percentage of fructose, which also yields color in the analytical methods for inulin unless removed by treatment with yeast or hot alkali. Two recent reports (2, 3) indicate that the clearance of the alkali-stable and alkali-labile frac-tions of inulin may not be equal. Since some com-mercial preparations of inulin (such as the one used in this study) may contain as much as 50 per cent of the alkali-labile material, considerable errors in estimation of glomerular filtration rate would occur if a difference in clearance of the two fractions exists. The present report indicates that the clearance of the two fractions is identical, within the limits of error of analysis, in confirmation of the prelimi-nary report by Cotlove (1).

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
