JOURNAL FREE ACCESSThe effects of guar gum on various parameters of glucose tolerance were studied in total gastrectomized and non-operated rats. The examined parameters included: (a) postprandial blood glucose response, (b) blood insulin response, (c) gastric emptying rate, and (d) glucose absorption rate. The animals were administered 250mg of glucose per 100g boby weight as 20% glucose solution, with or without guar gum dissolved at a 2% level.
After oral administration of glucose, the gastrectomized rats showed late hypoglycemia. Insulin secretion was also exaggerated, postprandial glucose level was significantly reduced, and hypoglycemia was retarded after the addition of guar gum to gastrectomized rats.
Addition of guar gum delayed the gastric emptying rate but did not affect the glucose absorption rate.View full abstractDownload PDF (410K) -

JOURNAL FREE ACCESSEnzymatic formation of methyl and ethyl β-D-fructofuranosides was investigated in aqueous methanol and ethanol extracts of Japanese persimmon fruits. The fruits were extracted with 60% methanol or 40% ethanol at 20°C for 24 hr. The extracts were concentrated and submitted to Dowex 1X2 (OH) column chromatography, to separate methyl and ethyl β-D-fructofuranoside for 13C-NMR and polarimetric analysis. The invertase in the persimmon was active considering the high concentration of methanol and ethanol. The formation of β-D-fructofuranosides in the alcoholic extracts of the fruits was due to the action of invertase. In extraction at 20°C for 24 hr, 40_??_50% methanol gave 10_??_15% methyl, and 20% ethanol, 3_??_6% ethyl β-D-fructofuranosides, to total mono and oligo saccharides (free sugars).View full abstractDownload PDF (174K) -

JOURNAL FREE ACCESSThe effects of wheat bran, Solka-floc and pectin on gastrointestinal transit time (TT) were investigated in ileorectostomized rats. After the operation, the rats were fed a fiber free diet (FF diet), a FF diet with 10% wheat bran (WB diet), a FF diet with 10% Solka-floc (SF diet) or a FF diet with 5% pectin (P diet) for 4 weeks (n=5, in each group). No significant differences were found in the growth rate of rats fed the FF diet, WB diet or SF diet. However, the growth of rats fed P diet decreased compared with the other hand, the WB diet or SF diet did not have any effects on TT. As it is well known that WB and SF diet decrease TT in the large intestine, over results here suggest that TT in the small intestine is delayed by feeding these dietary fibers.View full abstractDownload PDF (218K) -
