The tonsils are mucosa-associated lymphoid organs. Several details regarding their normal function and pathological alteration are still unknown. In this review the relationship of the tonsils to similar lymphoid organs is discussed, the possibilities of antigen uptake (M cells and micropores of the crypt epithelium) are demonstrated, and alterations of the(More)
Patients suffering from recurrent tonsillitis (RT), hyperplastic tonsillitis (HT) or idiopathic tonsillar hyperplasia (ITH) were compared in immunological studies with subjects showing clinically normal palatine tonsils. Serum concentrations of immunoglobulins, particularly IgG, were increased in association with tonsillitis. Conversely, the number of IgG-,(More)

The crypt epithelium of human palatinal tonsils is a specialized squamous epithelium characterized by the presence of intraepithelial passages which are filled by non-epithelial cells. The passages are covered by the so-called M cells. This reticulated epithelium (reticulum = network) is a highly differentiated one. In the present study immunohistochemical(More)
A new method for testing lactose intolerance was developed. The examination is performed by jejunoscopy using lactose dilution for provocation and sucrose for control. Macroscopic and microscopic changes in the jejunal mucosa are examined after administration of solutions. The results of this study demonstrated that lactose administration causes prompt(More)
