The study of a biological microobject from the standpoint three-dimensionality gives more correct and realistic vision. material included 8 preparations palatine labial salivary glands adult human individuals fixed in 4% glutaraldehyde solution phosphate buffer (pH 7.4). Following pre-fixation, object was cut into individual slices freshly prepared similar fixator adding 1% calcium chloride at ...

developmental disturbances of the tongue (aglossia, macroglossia, microglossia, and ankyloglossia) can adversely affect the development of the surrounding structures including the palate, alveolar process, and teeth. these developmental disturbances impair functions such as mastication, speech, and swallowing. ankyloglossia is of various types and may be associated with other syndromic features...

OBJECTIVE To determine an appropriate focus score cutoff for childhood Sjögren syndrome (SS). METHODS Labial salivary gland tissue from specimens from children with SS and age-matched controls was retrospectively identified and reviewed by a blinded oral pathologist. RESULTS The presence of any focal sialadenitis (focus score > 0 foci/4 mm(2)) was common among childhood SS samples but prese...

Objective-To study collagenase production in labial salivary glands in patients with Sjogren's syndrome (SS). Methods-Collagenases were localised in labial salivary glands by immunohistochemistry. Collagenase activity against triple helical type I collagen monomers in stimulated saliva was measured using sodium dodecyl sulphate polyacrylamide gel electrophoresis and laser densitometry; tissue i...

The head anatomy of Pselaphus heisei (Pselaphitae) is described and documented. structural features are evaluated in comparison with findings presented earlier studies on the subfamily, a special focus correlations predacious habits groundplan Pselaphinae. We found tentorium, labrum, maxillary palps, shape head, system dorsal pits sulci highly variable within reflecting multiple transformations...

BACKGROUND Human T lymphocytes infiltrating tissues in autoimmune diseases are known to express somatostatin receptors amongst other activation markers. In this study, we evaluated whether somatostatin receptor scintigraphy (SRS) using a radiolabelled somatostatin analogue ((99m)Tc-EDDA/tricine-HYNIC-tyr(3)-octreotide ((99m)Tc-EDDA/HYNIC-TOC)) is able to detect the presence of immune-mediated p...

The aim of this study was the evaluation of the value of labial biopsy in the differential diagnosis of sarcoidosis and Sjögren’s Syndrome and the value of immunohistochemical markers such as CD3, CD4, CD8, and CD20 at the immunopathogenesis. Fifteen labial salivary gland biopsies from patients affected by primary Sjögren’s syndrome, and 15 labial salivary gland biopsies from patients affected ...

OBJECTIVE Sjögren's syndrome (SS), an autoimmune disease of exocrine glands, typically starts at the time of adrenopause. We undertook this study to test the hypothesis that SS is characterized by an insufficient androgen effect at the target tissue level. METHODS We searched for androgen response elements (AREs) in the cysteine-rich secretory protein 3 (crisp-3) gene. Dehydroepiandrosterone ...
