    Abstract Background: Inflammation is considered to be a link between diabetes and central nervous system (CNS) disorders, including depression and anxiety. Metformin is suggested to have antioxidant, anti-inflammatory, and mood-improving effects. The aim of the current research was to investigate the effects of the antidiabetic drug metformin on depressive- and anxiety- like behaviors and oxidative stress in the brain in a rodent model of inflammation induced by lipopolysaccharide (LPS) in male rats.
    Materials and methods: The rats were treated as follows: (1) Vehicle instead of metformin and lipopolysaccharide, (2) Lipopolysaccharide (1 mg/ kg) + vehicle instead of metformin, (3-5) Lipopolysaccharide + 50, 100, or 150 mg/ kg of metformin. After the behavioral tests, including open field (OF), elevated pulse maze (EPM), and force swimming (FS) tests, the brains were removed, and malondialdehyde (MDA), nitric oxide (NO) metabolites, total thiol, catalase (CAT) activity, interleukin-6 (IL-6) and superoxide dismutase (SOD) activity were determined.
    Results: In the EPM, metformin increased the open arm time and entry and decreased closed arm time and entry. In the FS test, metformin lowered the immobility and increased active time compared to lipopolysaccharide. In the OF test, metformin increased total crossing and total distance, time spent, traveled distance, and crossing number in the central zone. As a result of metformin administration, IL-6, MDA, and NO metabolites were decreased while thiol content, SOD, and CAT activity were increased.
    Conclusion: The results indicated that the well-known antidiabetic drug metformin attenuated depressive- and anxiety-like behaviors induced by inflammation in rats. These beneficial effects are suggested to be due to their attenuating effects on neuroinflammation, oxidative stress, and NO in the brain.

    Abstract Sanguisorba minor (S. minor) has neuroprotective and antioxidant activities. However, its potential benefits in ameliorating learning and memory functions have been explored in no studies up to now. So, in the current study, rats were treated with S. minor hydro-ethanolic extract (50, 100, and 200 mg/kg, intraperitoneal (i.p.)) as well as rivastigmine (0.5 mg/kg, i.p.) for 21 consecutive days. Thereafter, their behavioral performance was assessed using Morris water maze (MWM) and passive avoidance (PA) tasks. Notably, 30 min before conducting the tasks, scopolamine was injected. Finally, the biochemical assessments were done using the brain tissue. The extract characterization was performed by liquid chromatography-mass spectrometry, which confirmed the presence of quercetin, myricetin, kaempferol, catechin, ellagic acid, and gallic acid derivatives. In the MWM test, the extract reduced both escape latency and the travelled distance, compared to the scopolamine group. Moreover, in the PA test, the latency to enter the dark chamber significantly increased by the extract, compared to the scopolamine group (p < 0.05-p < 0.001). Notably, the beneficial effects of S. minor on cognitive performance of the scopolamine-treated rats appeared to be similar or even better than rivastigmine in behavior performance. Similar to rivastigmine, it was observed that the extract attenuated both AChE activity and oxidative injury in the brain as evidenced by the increased antioxidant enzymes and total thiol content; however, it decreased malondialdehyde level (p < 0.05-p < 0.001). In conclusion, the results suggested the effectiveness of S. minor in preventing cognitive dysfunction induced by scopolamine. Accordingly, these protective effects might be produced by the regulation of cholinergic activity and oxidative stress. S. minor could be considered as a potential alternative therapy in cognition disorders.
