Сarbohydrate metabolism parameters under the glutamate-induced obesity in rats and concominant correction with probiotic strains of lactobacilli and bifidobacteria

Abstract

To find out the effect of probiotic strains on insulin resistance induced by glutamate-induced obesity in rats. Obesity was induced by neonatal administration of monosodium glutamate (4 mg/g,s.c.) at 2, 4, 6, 8, 10-day life. The introduction of probiotics started at the end of 4 week after birth and continued intermittently for 2-week courses. After 4 months, the rats of all groups glucose and insulin levels and insulin resistance index HOMA were analyzed. Neonatal administration of monosodium glutamate leads to the development of insulin resistance in rats 4 months of age. The periodic introduction of the combined probiotics prevented the development insulin resistance in rats. The most significant effect was revealed in the group of animals treated with the combined probiotic strains Lactobacillus casei IMVB-7280, Bifidobacterium animalis VKL, Bifidobacterium animalis VKB. The results suggest the effectiveness of the use of probiotic strains of bifidobacteria and to prevent the development of insulin resistance.
