The distribution of immunoglobulin-containing cells within 8 normal human labial salivary glands was studied using an immunoperoxidase technique. Cell counts revealed that IgA-containing cells pre-dominated in all specimens and that the mean percentage class ratios for IgG:IgA:IgM:IgD cells were 4:92:3:1. IgE cells were rare and only detected in one gland. The density of IgA cells (191 cells/mm...

Myoepithelioma is a rare benign neoplasm of salivary glands. Accounts for less than 1% of all salivary gland neoplasms. It is more common in parotid glands foIIowed by small salivary glands. Myoepithelioma once was considered as extreme variant of pleomorphic adenoma. But now many authors consider the myoepithelioma as distinct pathological entity as it i of myoepithelial cells and behaves more...

The western chinch bug, Blissus occiduus Barber, is a serious pest of buffalograss, Buchloe dactyloides (Nuttall) due to physical and chemical damage caused during the feeding process. Although previous work has investigated the feeding behaviors of chinch bugs in the Blissus complex, no study to date has explored salivary gland morphology and the associated salivary complex of this insect. Who...

This article discusses salivary gland disorders and provides nurses with a broad base of knowledge for use in planning and implementing perioperative patient care. Salivary gland disorders may be caused by nonneoplastic conditions or neoplasms. Nonneoplastic conditions generally are related to inflammatory processes or are secondary to existing disease processes. Neoplasms manifest themselves a...

The aim of this work was to study the feeding habits of the predator Brontocoris tabidus (Heteroptera: Pentatomidae) analyzing the salivary gland complex (SGC). The SGC was dissected and subjected to histological analyses and biochemical assays. Results showed that a pair of bilobed principal salivary glands and one pair of tubular accessory salivary glands form the SGC and different parts of s...

Objectives. To investigate the expression of IL-34 in labial salivary glands (LSGs) of patients with primary SS (p-SS) and its role in inducing a pro-inflammatory monocyte phenotype. Methods. LSG biopsies were obtained from 20 patients with p-SS and 10 patients with non-Sjögren’s sicca syndrome (n-SS). The expression of IL-34, IL-1b, TNF-a, IL-17 and IL-23 was assessed by real-time PCR. IL-34 e...

1. Salivary glands of the female ixodid tick, Dermacentor andersoni, secrete fluid in vitro when bathed in a slightly modified version of the mammalian tissue culture medium 'TC 199'. 2. Rate of salivation in vitro increases with progression of feeding, but there is no comparable increase in dry weight of the salivary glands during the early phase of engorgement. Engorged ticks secreted at only...

Hessian fly (Mayetiola destructor) larvae are thought to manipulate host growth and metabolism through salivary secretions. However, the transcriptome and proteome of Hessian fly salivary glands have not been systematically analyzed. In this research, we analyzed Expressed-Sequence-Tags (EST) representing 6106 cDNA clones randomly selected from four libraries made from dissected salivary glands...

Sclerosing Polycystic Adenosis (SPA) is a rare disease of the salivary glands, first described by Smith et al. in 1996, with histomorphological aspects similar to those from breast fibrocystic disorders1. Its pathogenesis is still unclear; however, it is considered a pseudo-neoplastic or reactive process. Recently, Skálová et al. showed clonality in six SPA cases. SPA affects mainly the parotid...

Adenoid cystic carcinoma (ACC) is a relatively uncommon tumor, with a reported incidence of 4.5 cases per million individuals . The age range for diagnosis is wide, with tumors arising at almost equal incidence in any decade of adulthood. The salivary and lacrimal glands are among the most common sites at which this tumor arises. It is the most common malignancy to arise in the minor salivary g...
