alpha-amylase e.c.3.2.1.1. (1,4 glucan, 4 glucanohydrolase) can be obtained from salivary glands, pancreas and microorganisms such as pseudomonas and asperigllus, as well as muscles and ovarian tubes.1.2 alpha-amylase from bacillus subtilis #1024(a tcc 465)* was purified with a highest degree of purity in our laboratory (31.59 u/mg). the extracellular alpha-amylase was subjected to different pu...

CONTEXT Stress is defined as an alteration of an organism's balance in response to a demand perceived from the environment. Diverse methods exist to evaluate physiological response. A noninvasive method is salivary measurement of cortisol and alpha-amylase. A growing body of evidence suggests that the regular practice of Yoga would be an effective treatment for stress. AIMS To determine the K...

BACKGROUND Good physical fitness seems to help the individual to buffer the potential harmful impact of psychosocial stress on somatic and mental health. The aim of the present study is to investigate the role of physical fitness levels on the autonomic nervous system (ANS; i.e. heart rate and salivary alpha amylase) responses to acute psychosocial stress, while controlling for established fact...

OBJECTIVE Oral lichen planus (OLP) is chronic inflammatory disease of the oral mucosa, presenting in various clinical forms. The etiology of OLP is still unknown but mounting evidence points to the immunologic basis of this disorder. AIM Our study was undertaken to quantify the salivary levels of pro-inflammatory tumor necrosis factor-alpha (TNF-alpha) in the reticular and the erosive/atrophi...

Alpha-amylase E.C.3.2.1.1. (1,4 glucan, 4 glucanohydrolase) can be obtained from salivary glands, pancreas and microorganisms such as Pseudomonas and Asperigllus, as well as muscles and ovarian tubes.1.2 Alpha-amylase from Bacillus Subtilis #1024(A TCC 465)* was purified with a highest degree of purity in our laboratory (31.59 U/mg). The extracellular alpha-amylase was subjected to differe...

BACKGROUND Epidermal growth factor (EGF) and transforming growth factor-alpha (TGF alpha) are potent gastric acid inhibitors and stimuli of mucosal growth and protection but their involvement in Helicobacter pylori associated duodenal ulcer has been little examined. AIM To assess gastric acid secretion, plasma gastrin concentrations, mucosal content of EGF and TGF alpha, and mucosal expressio...

We previously found that scavenger receptor cysteine-rich gp-340 (glycoprotein-340), isolated from lung or saliva, directly inhibits human IAVs (influenza A viruses). We now show that salivary gp-340 has broad antiviral activity against human, equine and porcine IAV strains. Although lung and salivary gp-340 are identical in protein sequence, salivary gp-340 from one donor had significantly gre...

A clonal cell with an acinar cell phenotype, which was induced by 5-azacytidine treatment of a neoplastic human salivary intercalated duct cell line, was cultivated in the presence of 1 alpha,25-dihydroxyvitamin D3. Morphological changes occurred; large cells that were polygonal or round in shape and had numerous vacuoles in their cytoplasm appeared in the treated cells, whereas the same concen...
