The intensity of WGA staining of the intestinal epithelium decreases along the length of the SI and can be reduced by N-acetyl-L-cysteine (NAC) treatment.

Abstract

<p>(A) Confocal micrographs of longitudinal sections of the proximal, medial and distal SI from infant mice treated with PBS or NAC after 6 h. The sections were stained with WGA (red) and DAPI (blue). Scale bar = 200 µm. (B,C) PAS stained sections of Carnoy's fixed proximal, medial and distal SI segments from untreated infant mice (B) and of the proximal SI from infant mice treated with PBS or NAC after 6 h (C). Scale bar = 100 µm. Arrow points to mucus layer.</p
