ABSTRACT
The stomach of three species of non-human primates was investigated by lectin histochemistry to clarify the staining affinity and distribution patterns of their sugar residues. All gastric regions, with little differences between the deep and superficial parts of the same region, were rich in. in N-acetylglucosamine and/or neuraminic acid. Although, the superficial regions of the gastric mucosa were scanty in N-acetylgalactosamine, a- D-glucose and a -D-mannose, the deep parts of the gastric mucosa were rich in these sugars. In conclusion, there is a difference among the mucosubstances of surface and foveolar mucous cells, mucous neck cells, and gastric gland cells. This indicates heterogeneous composition of gastric mucus, or mucus molecules with variations in the degree of glycosylation of their oligosaccharide chains in the different cells which suggest that lectin binding affinity in the gastric mucosa correlated mostly to the degree of cellular differentiation.
RESUMEN
El estómago de tres especies de primates no humanos fue investigado por histoquímica de lectinas para determinar la afinidad de tinción y los patrones de distribución de sus residuos de azúcar. Todas las regiones gástricas, con pequeñas diferencias entre las partes profundas y superficiales de la misma región, eran ricas en N-acetilglucosamina y/o ácido neuramínico. Si bien, las regiones superficiales de la mucosa gástrica eran escasas en N-acetilgalactosamina, a-D-glucosa y a-D-manosa, las partes profundas de la mucosa gástrica eran ricas en estos azúcares. En conclusión, existe una diferencia entre las mucosustancias de la superficie y células mucosas foveolares, células mucosas del cuello y células de las glándulas gástricas. Esto indica una composición heterogénea de la mucosa gástrica, o moléculas de moco con variaciones en el grado de glicosilación de sus cadenas de oligosacáridos en las diferentes células, sugieriendo que la afinidad de union de lectinas en la mucosa gástrica se relacionada principalmente con el grado de diferenciación celular.
