The aim of this clinical study was to investigate the acid resistance of enamel lesions remineralized in situ by a sugar-free chewing gum containing casein phosphopeptide-amorphous calcium phosphate nanocomplexes (CPP-ACP: Recaldent). The study utilized a double-blind, randomized, crossover design with two treatments: (i) sugar-free gum containing 18.8 mg of CPP-ACP, and (ii) sugar-free gum not...

A strategy for the unambiguous identification and selective quantification of xanthan gum and locust bean gum (LBG) in gelled food concentrates is presented. DNA detection by polymerase chain reaction (PCR) showed to be a fast, sensitive, and selective method that can be used as a first screening tool in intact gelled food concentrates. An efficient isolation procedure is described removing com...

This research work is aimed at decolourizing gum Arabic using activated charcoal so as to improve the quality of gum Arabic before the use of additives on the gum Arabic. The experiment was conducted on laboratory scale, the filter fixed bed method was used and the adsorbent (activated charcoal) is a granular of 500μm mesh size. The pH, viscosity and transmittance of each solution were measured...

Based on these approaches, several types of medications, such as taste adulterants, stimulants, and tranquilizers have been tested as aids to smoking cessation (Kozlowski, in press; Raw 1978; Grabowski and Hall, this volume). Most of these medications have not been efficacious. Nicotine chewing gum is the exception (Hughes and Miller 1984). The major hypotheses to explain the efficacy of nicoti...

Indian literatures mention the use of plants in treatment of various human ailments. In traditional system of drugs various plant parts such as stem, stem bark, roots, root bark, leaves, fruits and exudates are used in dysentery, diarrhea, diabetes, leucorrhoea, menorrhag...

Leucaena (Leucaena leucocephala) seed gum (LSG) was evaluated for disintegrant action in lactose (soluble) based tablets containing ibuprofen, a relatively insoluble drug. The properties of tablets evaluated include weight uniformity, hardness, friability, disintegration time and in vitro dissolution (k, T 50 , A 30 ). LSG, at low concentration level (2% w/w), can be used as a disintegrant in t...

Gum arabic is used throughout the world for various purposes including food additive and pharmaceutical excipient. The present study was undertaken to determine the effect of gum arabic on gastric ulcers in rats. The influence of gum arabic on the antiulcer activity of ranitidine, a known antiulcer drug was also evaluated. The antiulcer study was carried out in acetic acid induced chronic gastr...

Two experiments independently investigated the basis of the chewing gum induced context-dependent memory effect. At learning and/or recall, participants either chewed flavourless gum (Experiment 1) or received mint-flavoured strips (Experiment 2). No context-dependent memory effect was found with either flavourless gum or mint-flavoured strips, indicating that independently the contexts were in...

OBJECTIVES The finding that chewing gum can moderate state anxiety under conditions of acute stress has proved difficult to replicate. The present study examines the extent to which chewing gum can moderate state anxiety under conditions of acute social stress. METHOD In a between-participants design, 36 participants completed a task comprising a mock job interview (a variation on the Trier S...
