Blend Films of Waterborne Polyurethane-Carboxymethylated Guar Gum Crosslinked by Ca2+

Investigations on interpolymer complexes of cationic guar gum and xanthan gum for formulation of bioadhesive films

The present study was aimed at evaluating the possible use of inter polymer complexed (IPC) films of xanthan gum (XG) and cationic guar gum (CGG) for formulating domperidone bioadhesive films. Formation of bonds between -COO¯ groups of XG and -N(+)(CH(3))(3) groups of CGG was evident in the FTIR spectra of IPC films. Bioadhesive strength of the films was evaluated employing texture analyser. Wa...

Thermal Degradation of Guar Gum

Information about the thermal degradation of guar gum has been obtained from the time dependence of the viscosity at high temperatures measured using a slit viscometer. The viscosity is related to the molecular weight using previously published relations between the zero shear specific viscosity and the coil overlap parameter in conjunction with the appropriate Mark-Houwink equation. Unlike ani...

Reduction of serum cholesterol in hypercholesterolemic rats by Guar gum

Objective: Several diseases are reported to be uncommon in those parts of the world where dietary fiber intakes are high, therefore, in this study; we evaluated the hypocholesterolemiceffects of a dietary fiber (guar gum) in hypercholesteromic rats. Materials and Methods: Rats were fed high-fat or a normal fed diet for 12-week then treated with 5% guar gum in their regime during a 28 days peri...

Reduction of serum cholesterol in hypercholesterolemic rats by Guar gum

In the previous issue of AJP an article under the title of "Reduction of serum cholesterol in hypercholesterolemic rats by Guar gum" was published (Samarghandian et al., 2011), which raised some question to be discussed more. In the “Animal Experimental Procedure” section, for induction of hypercholesterolemia, rats have been fed a chow supplemented with 18% corn oil. This diet is absolutely a ...
