Effect of normal microbial flora on intestinal surface area

Gordon, Helmut A., Bruckner-Kardoss, Edith·1961·American Journal of Physiology-Legacy Content

Abstract

The mucosal surface area of the small intestine was determined in young adult, germfree and conventional rats. On the average, the germfree values were found to be 30% lower than those of conventional animals. This reduction was pronounced in the mid- and lower parts of the small intestine and relatively slight in the upper segment. It is assumed that the higher surface area values of conventional rats are due to the "physiologic" stimulation by the normal microbial flora.

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.
