Surface Features of theSmall Intestinal Mucosa in Severe Persistent Diarrhea Sandra de Martini Costa

1 - Thin section of the jejunal mucosa under light microscopy showing mild villous atrophy with the presence of eosinophils(e) and lymphocytes (L) within the epithelium. Microvilli are decreased in number and in height (x960)

2- Scanning electron microscopy of the jejunal surface; the enterocytes are recovered by a mucus material; lymphocytes (arrow) and fat droplets (g) are seen on the surface of the enterocytes (x 2,200)

3- Persistent Diarrhea - Scanning electron microscopy of the jejunal surface; the enterocytes are recovered by a mucus material; lymphocytes (arrow) and fat droplets (g) are seen on the surface of the enterocytes (x 8,000)

Intestinal Mucosa in Normal Infants Sandra de Martini Costa 1- Control - Thin section of the jejunal mucosa under light microscopy Epithelial cells (C) are well preserved and the Nuclei(N) is in a basal location; Microvilli (arrow) are uniformely distributed at the apical portion of the enterocytes. Globelet cell(*) are present between the enterocytes (x2,700).

2- Control - Scanning electron microscopy of the jejunal surface showing the distribution of the enterocytes (arrow) lining the villi and the microvilli on the top of the enterocytes (x2,200)
