The existence of a motor innervation to the secretory and myoepithelial elements of salivary glands has been supported amply by physiological and pharmacological studies extending over a century (reviewed in Babkin, 1950 ; Emmelin, 1967) . However, the exact morphological nature of this innervation at the acinar level is less well established, and has been the subject of several conflicting rep...

OBJECTIVES Among the diverse forms of amyloidosis, secondary type is the most frequent one. Diagnosis of amyloid deposition is based on the identification of the fibrillary protein amyloid by means of Congo Red (CR) or crystal violet (CV) stains, but these techniques do not differentiate between the different types of amyloid fibrils. The aim of this study was to identify by immunofluorescence ...

Labial gland secretions of 22 males of the bumblebee Bombus pomorum, collected in the Czech Republic, were analysed separately for each individual. The secretions contained 70 compounds among which saturated and unsaturated hydrocarbons strongly dominated. The proportion of hydrocarbons in the secretion was unusually high (85-100%) compared to other bumblebee species studied so far (3-15%). Met...

Stingless bees of the species Trigona spinipes (Fabricius 1793) use their saliva to lay scent trails communicating the location of profitable food sources. Extracts of the cephalic labial glands of the salivary system (not the mandibular glands, however) contain a large amount (approx. 74%) of octyl octanoate. This ester is also found on the scent-marked substrates at the feeding site. We demon...

Fifty-one patients with autoimmune rheumatic diseases underwent biopsy of the labial minor salivary glands. These patients were divided according to histopathology of lip biopsies into three groups (negative lip biopsy, 1+ and 2+). From all the patients stimulated parotid salivary flow was measured. In the saliva sodium, potassium, magnesium, alpha-amylase, and immunoglobulin levels (IgA, IgG, ...

Sjögren's syndrome (SS) is a complex, chronic, systemic, autoimmune disease that mainly affects the exocrine glands, especially the salivary and lacrimal glands, leading to dryness of the oral and ocular mucosae. Several factors have been studied that could explain the glandular hypofunction primarily related to water transport. Recent reports have shown alterations in secretory route and traff...

The labial minor salivary glands (LSGs) are easily accessible mucus-secreting structures of the alimentary tract that may provide new information on the basis of gastrointestinal complications of cystic fibrosis (CF). It was shown that they are destructed in the course of cystic fibrosis. We employed wide-field, micrometer resolution in vivo optical coherence tomography to assess the surface de...

salivary mucocele is a common lesion derived from minor salivary glands with various surgical or non-surgical treatment modalities. to evaluate the effect of a highly potent corticosteroid (dexamethasone) in the management of salivary mucocele, we performed intralesional injection of dexamethasone in nine patients with labial mucocele. complete healing of lesions observed in seven of nine patie...
