Sakata (1954) studied the fine structure of the attachment between lamina propria mucosae and the epithelium of the gingiva and the hard palate, and compared her observation with that of Odland (1950) , who reported on the attachment between epidermis and dermis. The present study deals with the junction between the mucous epithelium and the lamina propria mucosae of the esophagus of the adult ...

According to the 2010 WHO classification of digestive system tumors, esophageal low‐grade intraepithelial neoplasia (LGIEN) is associated with ultrastructural and cytological abnormalities confined to the lower half of the epithelium, and squamous cell carcinoma (SCC) is defined as tumor invasion of the lamina propria or penetration into deeper tissue layers. We here reported a rare esophageal ...

The aims of this paper were to establish the origin of cells producing IgA antibody to cholera toxoid in the lamina propria of the small intestine and to define the role of antigen in their distribution. The use of Thirty-Vella loops made it possible to restrict antigenic challenge to a defined segment of the intestine in rats which had been primed i.p. with toxoid in Freund's complete adjuvant...

Only recently has it become apparent that eosinophils play a crucial role in mucosal immune homeostasis. Although eosinophils are the main cellular component of the lamina propria of the gastrointestinal tract, they have often been overlooked because they express numerous markers, which are normally used to characterize macrophages and/or dendritic cells. To study their function in mucosal immu...

Oral submucous fibrosis is a chronic insidious disease and a well-recognized potentially malignant condition of the oral cavity. It is a collagen related disorder associated with betel quid chewing and characterized by progressive hyalinization of the lamina propria. Objectives: It is traditionally held that in oral submucous fibrosis the hyalinization process starts from the lamina propria and...

Hemangiomas of the tympanic membrane are extremely rare. We present the third reported case and, to our knowledge, the first capillary hemangioma of the tympanic membrane. These deep purple polypoid tumors are asymptomatic while small but enlarge slowly to erode adjacent structures. They arise characteristically from the lamina propria of the tympanic membrane without involving the middle ear. ...

linated nerve fibers and Schwann cells is found near blood capillaries in the lamina propria of the proventricular mucosa of the finch. At least two types of endocrine cells (type I and II) are present mainly in the lamina propria mucosae where they form a neuro-endocrine complex, but some cells of both types are also seen in the basal part of the epithelial layer like mammalian basal-granulate...
