Previous studies have shown that several factors--such as alloxan-induced diabetes, adrenalectomy, or removal of the thyroid-parathyroid gland complex--can influence the flow rate, protein concentration, and protein composition of rat parotid saliva. The present study was undertaken to explore further the influence of glucocorticoids and thyroxine on rat parotid saliva in hormonally intact anim...

Background and aims. The aim of this study was to evaluate the effect of different etching times on enamel color stability after immediate versus delayed exposure to colored artificial saliva (CAS). Materials and methods. Human first premolars were divided into five groups of twenty. A colorimeter was used according to the CIE system on the mid-buccal and mid-lingual surfaces to evaluate initia...

INTRODUCTION Saliva is a potentially important barrier against respiratory viral infection but its mechanism of action is not well studied. METHODS We tested the antiviral activities of whole saliva, specific salivary gland secretions, and purified salivary proteins against strains of influenza A virus (IAV) in vitro. RESULTS Whole saliva or parotid or submandibular/sublingual secretions fr...

h-point standard addition method (hpsam) was applied for the simultaneous determination of v(v) and fe(iii). the method is based on the complex formation of v(v) and fe(iii) with chromazurol s (cas) in acidic media and in the presence of cetyltrimethylammonium bromide (ctab) as a micellizing agent. acidic media and the presence of a micellar system improve selectivity and sensitivity. fe (iii) ...

Background: Saliva acts as a buffer system to maintain the optimal pH of mouth. The acidic saliva causes demineralization enamel resulting in dental caries. bromelain enzyme found pineapple skin can increase by inhibiting bacterial growth. This study aims determine effect gargling with peel extract solution (Ananas comosus(L) Merr) on salivary students SMPN 3 Bukit Apit.
 Methods: was usin...

Saliva substitutes and/or lubricants are commonly employed to lessen dry mouth symptoms by stimulating and/or substituting for the secretion of saliva. In this study, a novel artificial saliva containing inorganic salts, including sodium chloride and potassium chloride, and bactericidal agents, including potassium thiocyanate and lactoperoxidase, was formulated in the form of a solution (DM-sol...

H-Point Standard Addition Method (HPSAM) was applied for the simultaneous determination of V(V) and Fe(III). The method is based on the complex formation of V(V) and Fe(III) with chromazurol S (CAS) in acidic media and in the presence of cetyltrimethylammonium bromide (CTAB) as a micellizing agent. Acidic media and the presence of a micellar system improve selectivity and sensitivity. Fe (I...

Tannins have a number ofdetrimental biological effects and these include interference with normal growth and metabolism if they are present in the feed of various animals. Proline-rich proteins (PRPs) in saliva have been shown to provide protection against tannin, but little is known about the mechanism of protection and interaction of other salivary proteins with tannin. To identify tannin-bin...

The aim of the study was to characterise gastro-oesophageal reflux (GOR) in idiopathic pulmonary fibrosis (IPF). 40 consecutive IPF patients underwent pulmonary high-resolution computed tomography (HRCT) scan and impedance-pH monitoring while off antisecretory therapy. The presence of pulmonary fibrosis was assessed using validated HRCT scores. Reflux features included distal oesophageal acid e...
