Welan gum is a kind of novel microbial polysaccharide, which is widely produced during the process of microbial growth and metabolism in different external conditions. Welan gum can be used as the thickener, suspending agent, emulsifier, stabilizer, lubricant, film-forming agent and adhesive usage in agriculture. In recent years, finding optimal experimental conditions to maximize the productio...

materials and methods in a randomized clinical trial, 60 patients, scheduled for cesarean section were randomly divided in to 2 groups gum-chewing group (n = 30) and control group (n = 30) postoperatively. the patients in the gum-chewing group postoperatively chewed sugar free gum 3 times daily each time for 1 hour until discharge. the patients' demographic characteristics, duration of sur...

This study evaluated the effectiveness of nicotine chewing gum in smoking cessation, when incorporated into a behaviorally oriented self-help program. One hundred ninety-seven patients were randomly assigned to nicotine gum with a self-help manual, a self-help manual without gum, or a control condition, but received no further treatment from the prescribing physician. At six weeks, the nicotine...

Blue gum eucalyptus (Eucalyptus globulus) is a large tree native to Australia that was widely planted throughout California for reforestation, building and timber, but in some areas has spread beyond its planted borders and substantially altered wildlands. Due to its fast growth, large size and reproductive potential, blue gum’s impacts on native vegetation, wildlife and ecosystem processes are...

To determine the relative effects of expectancy and nicotine depletion on aversive withdrawal symptoms, we gave 109 smokers attempting to quit either nicotine gum or placebo within a balanced placebo design and monitored their withdrawal symptoms and smoking for 2 weeks. Subjects who believed they were getting nicotine gum reported less physical symptoms of withdrawal, showed less arousal, and ...

ABSTRACT Sterculia gum is a complex polysaccharide of high molecular weight. The rapid swelling of gum particles, their relative insolubility and their unusual resistance to bacterial and enzymatic breakdown make this gum suitable as a bulk laxative. The present work deals with development of granular formulation using Sterculia gum and its evaluation. The evaluation includes size gradation usi...

To assess mutans streptococci (MS) during xylitol gum chewing (mean 3.8 g/day, 2.9 times/day) for 13 months and then for 15 months after the intervention, Japanese mothers with high salivary MS were randomized into two groups: xylitol gum (n = 56) and no gum (n = 51). The proportion of low MS levels was highest at 3 months of consumption (48.8%), but was significantly lower compared to baseline...

Polysaccharide-polysaccharide interactions are attractive in the food, polymer and pharmaceutical systems because they may impart novel or improved functional properties to products and reduce costs. In this work, the rheological interaction of sage seed gum (SSG) as a novel hydrocolloid with xanthan gum (XG) was studied in the dilute region. The intrinsic viscosity of the XG-SSG mixture at fiv...

BACKGROUND In 1996, the US Food and Drug Administration (FDA) approved switching nicotine gum and patch from prescription to over-the-counter (OTC) status. Some expressed concerns that broader availability and lack of physician control might increase persistent use of nicotine replacement therapy (NRT)-that is, use beyond the period specified by the FDA approved label. OBJECTIVE To estimate t...

This was a single-center, prospective, cross-sectional study stratified by age and gender with the objective of determining the relationship between gum chewing history, salivary flow, and dental caries severity in adults. We enrolled 191 subjects aged 18-65 years who underwent assessments for gum chewing history, unstimulated salivary flow rate, salivary pH, and caries severity. Unstimulated s...
