The effectiveness of Okra gum in sustaining the release of propranolol hydrochloride in a tablet was studied. Okra gum was extracted from the pods of Hibiscus esculentus using acetone as a drying agent. Dried Okra gum was made into powder form and its physical and chemical characteristics such as solubility, pH, moisture content, viscosity, morphology study using SEM, infrared study using FTIR,...

GUM is a portable, parallel implementation of the Haskell functional language. Despite sustained research interest in parallel functional programming, GUM is one of the rst such systems to be made publicly available. GUM is message-based, and portability is facilitated by using the PVM communications harness that is available on many multi-processors. As a result, GUM is available for both shar...

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...
