Background and Aims: Under hyperglycemic conditions, inflammatory processes with damage to the peripheral nerves are involved in the occurrence of neuropathy. This study aimed to compare the anti-inflammatory effects of metformin (synthetic drug) with gallic acid (natural compound) in hyperglycemic conditions.
methods: Hyperglycemia was induced in male rats by the intraperitoneal injection of Streptozotocin (STZ) at a dose of 60 mg/Kg. For this research, rats were divided into four groups. Two groups were healthy control and hyperglycemic control rats that did not receive any drugs. And the other two groups were hyperglycemic rats, which respectively received Metformin at a dose of 300 mg/kg/day and Gallic acid at a dose of 40 mg/kg/day. At the end of the 8-week period, the rats in all groups were anesthetized and a sample of their sciatic nerve was taken to measure the expression level of genes related to pro-inflammatory cytokines IL-6, IL-1β and TNF-α. Data analysis was done by SPSS software and comparison between average data was done by one-way ANOVA and Tukey's post hoc test.
Results: Induction of hyperglycemic conditions in rats increased the expression of genes related to pro-inflammatory cytokines IL-6 (p=0/000), IL-1β (p=0/008) and TNF-α (p=0/005). However, administration of metformin and gallic acid to hyperglycemic rats for 8 weeks reduced the expression of IL-6, IL-1β and TNF-α genes (p˂0.05).
Conclusion: Gallic acid, like metformin, with its anti-inflammatory prperties, can be effective in improving complications caused by hyprerglycemic conditions, especially neuroinflammation.
