In this research, a method for producing gum tragacanth (GT) fibers is presented. Ribbon type GT of Astragalus Gummifer species were obtained from local production lands. The gum was treated with alkali to increase its process ability, and allowed to stand for a period of time to reach the proper viscosity and/or to "ripen". Samples with different ripening times were prepared and their viscosit...

MAGNESIUM PEMOLINE : FACILITATION OF MAZE LEARNING WHEN ADMINISTERED IN PURE DIMETHYLSULFOXIDE* Donald G. Stein, John J . Brink and Arthur Patterron Clark University, Worcester, Massachusetts (Received 12 October 1967 ; in final form 30 November 1967) Recent studies attempting to facilitate teaming with magnesium pemoline have provided conflicting results . Lack of an effect on teaming has been...

The potential of arid/semiarid land plants a s sources of commercial products is illustrated by the following examples: candelilla (wax); jojoba (oil, protein); Acacia spp. (gum); Astragalus spp. (tragacanth gum); guayule (rubber); rabbitbrush (rubber, chemicals); sunflowers (rubber, chemicals); yucca (soap); and cresote bush (antioxidants, phenolic resins). co-evolutionary selection is a cause...

We introduce a new smooth, non-toxic, biocompatible method for cross-linking of gum tragacanth (GT), a polysaccharide of natural origin, in order to serve as a new supporting matrix for immobilization systems. The modified gum is used as a matrix for the catalysis of the conversion of benzyl penicillin to 6-aminopenicillanic acid (6-APA) by means of Escherichia coli ATCC11105 with penicillin G ...

The exact mechanisms by which non-starch polysaccharides increase stool output are unknown. In the present study the hypothesis that the site of fermentation and short-chain fatty acid (SCFA) accumulation is related to the action of non-starch polysaccharides (NSP) on stool output was tested. The basal diet (45 g NSP/kg) of forty-three male Wistar rats was supplemented with 50 g/kg of either gu...

BACKGROUND In Iranian traditional medicine, gum obtained from Astragalus gummifer and some other species of Astragalus was used as analgesic agent. OBJECTIVE In this study, we investigated the antinociceptive effect of several concentrations (125, 250, and 500 μg/kg body weight) of Astragalus gummifer gum (AGG) on thermal and acetic acid induced pain in mice. MATERIALS AND METHODS AGG was d...

BACKGROUND AND THE PURPOSE OF THE STUDY Extrusion-spheronization is an established technique for the production of pellets for pharmaceutical applications. In this study, the feasibility and influence of the incorporation of acacia, by itself and in combination with tragacanth, on the ability of formulations containing 2 model of drugs (ibuprofen and theophylline) to form spherical pellets by e...

It generally is accepted that a diet high in fiber, decreased dietary fat content were present. Thus, it has not been possible to determine if dietary fiber was patticularly soluble fiber, is useful in the management playing a significant role. The of studies in of the plasma glucose concentration in individuals with diabetes. This is one of the reasons several which specific, defined fibers ha...
