The Tonsils and Nasopharyngeal Epidemics

The Tonsils and Nasopharyngeal Epidemics.

Nasopharyngeal Tonsils (Adenoids) Contain Extrathymic Corticothymocytes

Adenoidal tissue (also known as nasopharyngeal tonsils) of 58% of humans in the pediatric age group contains immature T-lymphoid cells with the phenotype of thymocytes (TdT+, CD1abc+, cytoplasmic CD3+, coexpressing CD4 and CD8, lacking an Intraepithelial Lymphocyte-associated phenotype). The notable difference in comparison to palatine tonsils is the clustering in groups and sheets, comprising ...

QUANTITATIVE IMMUNOHISTOCHEMICAL INVESTIGATION OF IgA1 AND IgA2 IN NASOPHARYNGEAL AND PALATINE TONSILS

Localization of IgA1,2 positive objects has been studied quantitatively in the palatine and nasopharyngeal tonsils of 20 patients with pathological recurrent tonsillitis or adenoid hyperplasia. We found expression of IgA1 and IgA2 positive objects both in the tonsillar parenchyma and epithelium with predomination of the IgA1 subclass. An attempt was made to connect the morphological changes in ...

Some Tips about Tonsils and Adenoid Tonsil

This is an artic.:le about the pharyngeal lymphoid tissue. so called waldyer's ring. I have tride to give a rather clear discription of Its functi<"m, especially pointing to Its role in protecting the body against the infections by promoting the antibodv production and lymphocite formation.  In the view of these functions a clear cut indi­cations and contraindications of adenotonsillectomy has...

Tonsils and adenoids.

The bacteriology of acute tonsillitis and the normal flora of the throat in children is interesting and somewhat puzzling. Several studies (Box, Cleveland and Willard, 1961; Reilly et al, 1981; Toner et al, 1986) have shown that the culture of throat swabs taken from children with a history of acute tonsillitis does not differ, in terms of organisms cultured, from those taken from normal childr...
