[Histochemical and immunohistochemical study of jejunal mucosa cells in children with celiac sprue].
In the jejunal mucosae of 45 children with coeliac sprue (24 cases in the florid stage and 21 cases in remission) and 19 children without signs of affection of the small intestine a quantitative investigation was made of cells in the lamina propria which were visualized selectively by histochemical and immunohistochemical methods-plasmocytes with IgA, plasmocytes with IgM, plasmocytes with IgG, cells containing IgE, mast cells, eosinophil and neutrophil leucocytes. The objective was to find which of the above cells will best reveal by a change of their number the pathological process in the lamina propria of children with coeliac sprue and which has the greatest informative value on the present state of the lamina propria. It was found that plasmocytes with IgG and cells containing IgE are good markers of the activity of coeliac sprue in the lamina propria. The best marker of the activity of coeliac sprue in the lamina propria are mast cells detected by the histochemical reaction for tryptase using Z-Ala-Ala-Lys-MNA. This reaction detects mast cells also in non-fixed bioptic material.
