Abstract :
Based on the increasing prevalence of type 2 diabetes, the present study aimed to investigate the effect of Lactobacillus isolated from dairy products on blood glucose in diabetic rats. Isolation and characterization of Lactobacillus from dairy products were performed using biochemical and molecular tests. In this study, treatment was performed on 49 male Wistar rats with a mean age of approximately 6 to 8 weeks. Rats were divided into 7 groups of 7 each. In the intervention group, Lactobacillus ruteri and Lactobacillus plantarum were used. At the end of 4 weeks, weight changes and blood glucose levels of the rats were compared to the positive and negative controls. Statistical analysis was performed using SPSS software, chi-square test, or Fisher's exact test for comparison of variables. The results showed that during one month the mice were exposed to Lactobacillus bacteria had the highest weight in the fourth week and the lowest weight in the first week of the study. A significant decrease in blood glucose level was observed in the groups consuming L. plantarum and L. ruteri. The present study showed that intervention of Lactobacillus without altering diet or specific diet in rats can significantly decrease blood sugar in the bacterial group. Considering the effect of the studied bacteria on blood glucose reduction, it can be claimed that Lactobacillus can be suggested as an adjunctive treatment in patients with type 2 diabetes.
