The activity and composition of leafhopper saliva are important in interactions with the host rice plant, and it may play a physiological role in detoxifying toxic plant substances or ingesting sap. We have characterized diphenoloxidase in the salivary glands of Nephotettix cincticeps, its activity as a laccase, and its presence in the watery saliva with the objective of understanding its funct...

Background: One of the main dental and oral health problems that occur throughout world is caries. Cariogenic bacteria such as Streptococcus mutans Lactobacillus acidophilus are microorganisms cause Saliva plays a significant function in maintaining optimal cavity especially because its components pH, flow, buffering capacity. These three have role initiation development Gargling one activities...

The measurement of cortisol and 17-hydroxyprogesterone (17-OHP) in saliva has become a reliable tool for both the scientist and the clinician for studying adrenal cortical function in the adult and the older child. We have now established in parallel normative data for salivary cortisol and 17-OHP levels in healthy neonates. We have asked whether or not there is a circadian rhythm of cortisol a...

Tyrosylprotein sulfotransferase (TPST), the enzyme responsible for the sulfation of tyrosine residues, has been identified and characterized in submandibular salivary glands previously (William et al. Arch Biochem Biophys 338: 90-96). Tyrosylprotein sulfotransferase catalyses the sulfation of a variety of secretory and membrane proteins and is believed to be present only in the cell. In the pre...

Aim of the study is to evaluate the correlation between dental caries and salivary flow, pH and buffering capacity in young adult South Indian population. According to DMFT scores eighty subjects between 20 to 30 years of age were divided into four groups. Saliva samples collected were estimated for salivary flow, pH and buffering capacity and the data was statistically analysed. The pH, flow r...
