RESUMO
Background: Curcumin is active ingredient of turmeric The main purpose of this study is evaluating impact of curcumin on suger, hypoalgesia and inflammatory factors in diabetic mice. Materials and methods: Male mice divided into six groups of 6. One group as a negative and the other five groups injected with Streptozotocin (STZ) (200 mg/kg). Diabetic mice in each group given different treatments for twenty-one days.After that, blood sugar and neuroathy studies have been done and tissue samples the liver were studied for gene expression. Result: Curcumin reduced blood sugar, but the rate of hypoglycemia was significantly lower than metformin group P > 0.05, and the comparison of the synergistic effect of curcumin and metformin with metformin was not significant P > 0.05. Also, in neuropathy studies, the groups which recieved curcumin and metformin have shown a significant difference with diabetic group P < 0.01, Also, by evaluating inflammatory factors, there was a significant difference in the expression of TNF-a, IL-6 and NfkB, but there is no significant difference in the expression of Sirt1 P < 0.05. Conclusions: The analgesic effect of curcumin was quite evident, probably due to the significant impact of this herbal drug in reducing the expression of inflammatory genes NF-kB, IL6, and TNF-α.
