The exceptional abilities of stink bugs (Hemiptera: Pentatomidae) to colonize a diverse group of plants have been attributed to the feeding behaviors and the functions of the salivary complex of these insects. Here, we describe the ultrastructure of the salivary glands of the Neotropical brown stink bug, Euschistus heros, which is a major component of the pentatomid pest complex on soybeans, Gl...

Background: Solitary, nodular lesions of the oral mucosa present a clinical dilemma with their similar presentation to physician. The that appear on ventral surface tongue, soft muscular organ are distinct and even rarer varied manifestations. It may occur in different locations due trauma or obstruction minor salivary gland ducts lower lip as predominant site, often overlooked during screening...

Purpose: The purpose of this study was to examine whether cytomegalovirus (CMV) is present in different histological types of salivary gland cancer (SGC) by detecting CMV immediate-early (IE) and early gene products, and to determine the presence of its association with the overexpression of interleukin (IL)-6. Methods: Immunohistochemical analysis of 92 cases of different histological types of...

The salivary system of the Hymenoptera consists of the mandible, hypopharynx and thoracic salivary glands. It is very important because it is related to various aspects of the life of the insects, such as pheromone production, feeding the young, food digestion and nest building. Adult Polistes versicolor (Olivier) individuals were dissected, the thoracic salivary glands removed and processed fo...

Metallothioneins (MTs) are metal-binding proteins that have been regarded as intrinsic factors for protecting cells and tissues from metal toxicity and oxidants. Among the three major classes of MTs, MT-III is different from other MTs because it has neuronal inhibitory activity and is only expressed in the central nervous system. Recent studies, however, have confirmed that MT-III is also expre...

The growing widespread usage of cell phones has resulted in potential negative impacts on human health due to their use near the location salivary glands, which might be affected by non-ionizing radiofrequency radiation emitted from phones. purpose study was investigate effect electromagnetic waves glands male albino rats. Albino rats (n =42) were divided into 6 groups = 7 per group). Group I, ...

Mucoepidermoid carcinoma (MEC) is a malignant neoplasms of the salivary glands which is rarely found in childhood. Its incidence rate has been reported to be 0.44 per 100,000.1 Most of them arise from the parotid gland (64 – 80%) while other locations that are less frequent include submandibular gland, sublingual gland, minor salivary glands and lacrimal gland.2 Submandibular gland cancer is ex...

Specimens from parotid salivary glands of full-grown elephant Loxodon­ to offlcana a (n =6) and saliva aspirated from their main excretory ducts were examined macroscopically and microscopically and analysed bloohemlcally. The composition of the saliva was compared to that of the blood. The parotids (n=12; x = 7,4 kg) are homocrlne and of a seromucous nature. Myoepithelial celfs are well-develo...

Sclerosing polycystic adenosis (SPA) is a rare tumor-like lesion of the salivary gland that bears a histomorphological resemblance to fibrocystic disease and sclerosing adenosis of the breast. The lesion is widely considered to be a pseudoneoplastic inflammatory process. However, foci of epithelial dysplasia and carcinoma in situ can occur in the lesion. We report a case of 16-year-old Thai fem...
