This study was conducted to assess the effect of prebiotic galactooligosaccharides (GOS) on alloxan-induced diabetes in male Sprague-Dawley (SD) rats. Diabetes was induced by administration of alloxan (100 mg/kg) and rats were divided in 4 groups: normal control group (NCG), prebiotic control group (PCG), diabetic control group (DCG) and diabetic prebiotic(More)
