The effect of chronic alcohol intoxication and smoking on the output of salivary immunoglobulin A (IgA) was studied in 37 volunteers: 17 male smoking patients after chronic alcohol intoxication (AS) and 20 control non-smoking male social drinkers (CNS). The DMFT index (decayed, missing, or filled teeth), gingival index and papilla bleeding index (PBI) were assessed. Concentration of IgA in sali...

Salivary cortisol and secretory immunoglobulin A (S-IgA) are important biomarkers for environmental and public health research. The present study investigated the diurnal variations of these salivary biomarkers, with a focus on the change of distribution characteristics (i.e., skewness and kurtosis) of the concentrations. The participants in this study were 113 healthy young males. Salivary sam...

The interaction between the behavioral and physiological immune systems provides fertile ground for research. Here, we examine the interactions between fear of disease, collectivism/individualism, disgust, visual perception and salivary IgA. First, we parsed collectivism/individualism into ancestry and psychological processes and examined their relationships to fear of disease. Both ancestral a...

AIMS To assess and compare the self perceived work related stress among emergency department (ED) and general ward (GW) nurses, and to investigate its relation with salivary IgA and lysozyme. METHODS One hundred and thirty two of 208 (63.5%) registered female ED and GW nurses participated in the study. A modified mental health professional stress scale (PSS) was used to measure self perceived...

conclusions the current study indicated that the immunoreactivity of secretory iga might have no direct correlation with the colonization of indigenous flora and rejection of exogenous strains in adults. the relationship of microbes, host and dental caries should be in the light of coevolved microecosystem as a whole, but not caused by one factor alone. results the results showed that naturally...

Introduction: Oral local immune factors may play a protective role against oral diseases and defend against microbial agents. Salivary immunoglobulin A (IgA) is a major factor for the local host defence against caries and periodontal disease. The aims of this study were to determine the concentrations of salivary IgA and IgE levels in breast-fed and formula-fed children in infancy period. Metho...

The initial infection of children by Streptococcus mutans, the main pathogen of dental caries, depends on the ability of S. mutans to adhere and accumulate on tooth surfaces. These processes involve the adhesin antigen I/II (AgI/II), glucosyltransferases (GTF) and glucan-binding protein B (GbpB), each a target for anticaries vaccines. The salivary immunoglobulin A (IgA) antibody responses to S....

Circulating IgG anti-cyclic citrullinated peptide antibodies (CCP) are highly specific for rheumatoid arthritis (RA) and prognostic of poor outcome. Serum IgA anti-CCP occurs in a subset of IgG-positive cases and relates to still more aggressive disease. Mucosal IgA-class antibodies, however, are generally associated with anti-inflammatory actions and systemic tolerance induction. In the presen...

Objective: The aim of the study was to compare salivary IgA and gingival crevicular fluid levels in caries active free subjects. Methods: carried out on 40 subjects divided into two groups, Group I free, (DMFT =0) II active, >10). Saliva samples were obtained plaque index, volume flow rate determined. S. mutans lactobacillus determined by culture. concentrations saliva using ELISA. Data ...
