Alterations of the oral ecosystem in children with celiac disease.

Unlabelled: The aim of this work is to evaluate the alterations of the oral ecosystem in symptomatic children with celiac disease (CD), to establish a particular pattern of oral markers that can be used as presumptive diagnosis of CD.

Material & Methods: A sample of n=52 children with CD diagnosis according to the modified criteria of the European Society of Pediatric Gastroenterology and Nutrition (ESPGAN), 1990, was studied. A dental clinical evaluation of soft and hard tissues was performed.

Effect of the high molecular weight chitosan and sodium alginate on Candida albicans hydrophobicity and adhesion to cells.

Unlabelled: The aim of the present paper is to evaluate the effect of the high molecular weight chitosan (HMWC) and of sodium alginate (NaAL) on surface hydrophobicity of Candida albicans and on adhesion of the yeast to epithelial cells and fibroblasts of different proceeding. For this study, a collection strain and seven isolates of C. albicans from saliva (patients with denture stomatitis) were grown in Sabouraud glucose agar supplemented with HMWC or NaAL or in absence of them (control).

[High molecular weight chitosan and sodium alginate effect on secretory acid proteinase of Candida albicans].

The effect of high molecular weight chitosan (HMWCh) and sodium alginate (NaAL) on acid proteinase secretion of Candida albicans (one of culture collection and five isolates) was evaluated. The secretion of acid proteinase was induced in the presence and the absence of these polymers in different concentrations and their enzymatic activity was determined. HMWCh and NaAL significantly diminished the enzymatic activity (>76% for the collection strains and > 89% for the isolates, p < 0.

Effect of Chitosan and Sodium Alginate on the adherence of autochthonous C. Albicans to oral epithelial cells (in vitro).

The aim of the present study was to evaluate the effect of Heavy Molecular Weight Chitosan (HMWCh) and Sodium Alginate (NaAl) on fungal adherence. C albicans was identified and isolated from non-stimulated saliva extracted from male and female healthy adults. The minimum inhibitory concentration (MIC) was determined for each of the biopolymers.
