Abstract
In patients with cerebral ischemia, both during hospitalization and in the community, the prevalence of major depression is evident. Since the depression has a negative impact on recovery, its timely diagnosis and treatment is essential. This study aimed to evaluate the effect of the oral administration of Chevilan extract (Ferulago angulata hydroalcoholic extract; 100, 200 and 400 mg/kg) on brain oxidative stress indices and depression after permanent bilateral common carotid artery occlusion or ischemia/hypoperfusion in male adult rats. A number of 35 rats were divided into a control group, an ischemic group and ischemic groups receiving doses of 100, 200 and 400 mg/kg of Chevilan extracts for 14 days by gavage. To make animal models of permanent cerebral hypo perfusion/ischemia, right common carotid artery was ligatured first and the left one ligatured with an interval of one week. To evaluate depression, immobility in the forced swimming time of each rat was measured and then the rat’s brain tissues were extracted to separate hippocampus and measure malondialdehyde. The results showed that ischemia/hypoperfusion increased brain oxidants such as lipid per oxidation (LPO) and immobility. Also, ischemic rats treated with all three doses of the Chevilan show significant reduction in the concentration of MDA hippocampus and in immobility time at a dose of 100 mg/kg and 200 / 400mg, respectively. Increased swimming time was observed in all three groups of extract recipients. It was found that Chevilan extract with antioxidant effect can reduce the side effects of ischemia such as depression.

Abstract
From ancient times, plants have been regarded as therapeutic agents, in addition to their usage as food. Plants are rich sources of antioxidant and phenolic compounds. Lavandula angustifolia and Melissa officinalis are medicinal herbs rich in antioxidant compounds. The aim of this study was to compare the antioxidant and anticancer properties of Lavandula angustifolia and Melissa officinalis extracts using aqueous, ethanol and methanol solvents, to select the best extraction methods and solvents and to evaluate the cytotoxic effect of the extracts on HeLa, OVCAR-3 and MCF-7 cancer cell lines. Methanol, aqueous and ethanol extracts were obtained from the dried leaves of the plants and the antioxidant activities of each extract were measured by DPPH and FRAP methods. Finally, the anticancer effects of the extracts on HeLa, OVCAR-3 and MCF-7 cancer cell lines were evaluated by MTT assay in order to identify the most efficient extract. Comparing the results of total antioxidant assay showed that the highest amount belonged to the ethanol extract of Melissa officinalis and Lavandula angustifolia methanol extracts using lyophilization method. The IC50 value of ethanol extract of Melissa officinalis was equal to 0.028 mg/ml on OVCAR-3 cells, which was the best result obtained in comparison with other solvents, and the ethanol extract of Lavandula angustifolia with IC50 = 2.07 mg/ml on MCF-7 cells was the most effective extract among the others. In HeLa cell-line, methanol extract of Lavandula angustifolia with IC50 = 7.36 mg/ml showed the highest cytotoxicity. In this study, for the first time, the effects of different extracts of Lavandula angustifolia and Melissa officinalis on MCF-7, OVCAR-3 and HeLa cancer cells were evaluated and the results showed that ethanol and methanol extracts of these plants had better toxic effect on cancer cells.
