MAJOR SALIVARY GLANDS OF BOTH HUMANS AND RODENTS CONSIST OF THREE PAIRS OF MACROSCOPIC GLANDS: parotid, submandibular, and sublingual. These glands secrete serous, mucous or mixed saliva via the proper main excretory ducts connecting the glandular bodies with the oral cavity. A series of discoveries about the salivary ducts in the 17th century by Niels Stensen (1638-1686), Thomas Wharton (1614-...

The biological properties and underlying genetics of gastric cancer and gastric intestinal metaplasia evolve with neoplastic progression from the genetics of the original gland cell. PCR assay with crypt isolation was used in tumors from 20 patients to examine microsatellite alterations (allelic imbalance at 17p, 5q, 18q, 3p, 4p, and 9p, and microsatellite instability) in glands from each tumor...

AIM To make a quantitative evaluation by image analysis of oestrogen receptors, progesterone receptors, and androgen receptors in papillary hidradenomas and anogenital sweat glands. METHODS 20 papillary hidradenomas and the anogenital sweat glands detected in surgical specimens selected from 10 vulvectomies for squamous carcinoma, eight haemorrhoidectomies, and one anal polypectomy, all from ...

The distribution of amylase in rat parotid glands and von Ebner's glands was examined using ion etching-immunoscanning electron microscopy, which enables both light and electron microscopic observations of identical semi-thin resin sections immunolabeled with anti-α-amylase and immunogold in association with silver enhancement. At the light microscopic level, most acinar secretory granules (SG)...

The lacrimal and third eyelid superficial glands produce the aqueous component of the preocular tear film. In this research, morphologic and morphometric assessments of the parenchyma and stroma of both lacrimal glands of healthy adult mongrel dogs were performed. Both lacrimal and third eyelid glands of fourteen dogs were collected, summing fiftysix samples. The macroscopic and morphometric da...

The non-obese diabetic (NOD) mouse is chosen among other experimental models to study autoimmune sialadenitis resembling Sjögren's syndrome (SS), because of its unique characteristic of developing salivary dysfunction. Based on the deep loss of nitric oxide synthase (NOS) activity in parotid glands of NOD mice observed from early stages of disease and the inhibitory effect of nitric oxide (NO) ...

Whereas lymph vessels in some endocrine glands have been thoroughly investigated, data on these vessels in human parathyroid glands are often contradictory and deficient in available literature. Therefore, the aim of this study was to histomorphologically investigate whether lymph vessels could be found in human parathyroid glands postnatally and, if so, whether their presence was age- and gend...

ABSTRACT The parasitoid Diachasmimorpha longicaudata is an important control agent for several species of fruit flies. Research on the characteristics reproductive system and biology this can be valuable studies in taxonomy phylogeny insects order Hymenoptera. In study we analyzed histology histochemistry male D. longicaudata. consists a pair testes, two accessory glands, ejaculatory duct. Each...

Aims: To detect the presence of human herpes virus 6 (HHV6) and endogenous biotin in paraffin wax embedded and frozen salivary glands. Methods: Two stage indirect and streptavidin-biotin immunoperoxidase techniques were used to visualise the antigens. Results: HHV6 could not be shown in any of the tissues. However, considerable endogenous biotin antigenicity was detected in the glandular elemen...

Brunner's glands are rarely the seat of pathological change. Cases of solitary adenoma arising in the glands are reported (Jacobius, 1940; Cattell and Pyrtek, 1949; Culver and Caccese, 1957; Stephens and Harbrecht, 1958) and carcinoma has been noted on one occasion (Christie, 1953). In addition, it is known that diffuse hyperplasia, producing lobulated masses of glands, may occur; it is difficu...
