The polysaccharide exuded by Acacia decurrens trees contains residues of D-galactose , LArabinose , L-Fucose and Dglucuronic acid. An examination of the OMethyl derivatives of the gum yields 2,3,4,6 tetra –O-methyl –D-galactose, 2,3 –di-O-Methyl –L-arabinose , 2,3,4-triO-methyl-D-galactose, 2,4-di-O-methyl-D-galactose together with 2,3,4 tri-O-methyl-Dglucuronic acid by acid hydrolysis. The deg...

ultrasound-assisted extraction was used to determine the optimum processing conditions and to achieve the maximum extraction yield and viscosity of the gum extracted from quince seed. using response surface methodology (rsm) to design the experiments and adopting the central composite rotatable design (ccrd), the effect of extraction temperature (25-55°c), time (3-10 minutes), and ph (6-8) were...

PURPOSE The present investigation is to study the influence of metronidazole and tinidazole on the usefulness of guar gum, a colon-specific drug carrier based on the metabolic activity of colonic bacteria, using matrix tablets of albendazole (containing 20% of guar gum) as a model formulation. METHODS The matrix tablets of albendazole were subjected to in vitro drug release studies in simulat...

PURPOSE This study was designed to examine the ability of sodium hexametaphosphate delivered from a chewing gum to prevent extrinsic tooth stain formation. METHODS This study was a negative-controlled, randomized, two-period crossover design, with a 10-day washout period between treatments. The two treatments were a chewing gum containing 5.6% sodium hexametaphosphate and a negative control c...

INTRODUCTION Radiation-induced xerostomia is a frequent late side effect after treatment for oral and oropharyngeal cancers. This may induce swallowing difficulties, compromised oral well-being, reduced nutrition intake, or speech deficiencies. Consequently, quality of life is often impaired for these patients. OBJECTIVES The purpose of this study was to investigate the possibility to mechani...

Rumination involves regurgitation of previously ingested food, rechewing the food, and reswallowing it. In the current study, a child with autism displayed chronic rumination, resulting in the decay and subsequent removal of several teeth. After several treatments failed, including thickened liquids and starch satiation, the participant was taught to chew gum. His rumination decreased significa...

For evaluating N(2) fixation of diazotrophic bacteria, nitrogen-poor liquid media supplemented with at least 0.5% sugar and 0.2% agar are widely used for acetylene reduction assays. In such a soft gel medium, however, many N(2)-fixing soil bacteria generally show only trace acetylene reduction activity. Here, we report that use of a N(2) fixation medium solidified with gellan gum instead of aga...

BACKGROUND Postoperative ileus (POI) is a common complication following caesarean section. It impairs patients comfort; delays wound healing and prolong duration of hospital stay. Several methods have been used in the management of this condition with varying efficacy. Chewing gum postoperatively is a recent concept in the western world being advocated as a cost effective and comfortable manage...

Root caries is not exclusive to older individuals. Any caries-prone patient having gum recession can develop root caries. However, the elderly are usually more vulnerable to root caries because of several conditions. First, older patients are more likely to experience gum recession. Gum recession exposes the root of the tooth, which is softer than the enamel-covered crown of the tooth. Conseque...
