Abstract
Background: Postpartum depression (PPD) is a major depressive disorder and one of the most common complications of childbearing. PPD has a serious impact on the quality of life of all family members. Oxidative stress is one of the contributing factors in pathophysiology of major depression. Thus, drugs with potential antioxidant action could be an attractive target for treatment of depressive disorders. Matricaria Chamomilla and Selenium are natural sources of antioxidant. The aim of this study was to evaluate effects of oral administration of Matricaria Chamomilla aqueous extract and Selenium on experimental model of progesterone-induced postpartum depression and plasma oxidant-antioxidant system in mice.
Methods: Seventy adult female mice in seven groups were used in this study. All animals received daily injections of progesterone 5 mg/kg intraperitoneally for five days after which progesterone was withdrawn for three days. After modelling postpartum depression with progesterone withdrawal, Matricaria Chamomilla 300 mg/kg and Selenium 0.1 mg/kg and their combination were administered via gavage and imipramine 15 mg/kg was administered intraperitoneally one hour before open field and forced swimming test (FST). In order to investigate the role of oxidant-antioxidant system, PAB and MDA were meatured.
Results: All the treatment groups and the standard group spent less immobility time than the control group (P<0.05). Significant changes in the oxidative parameter (PAB and MDA) were not observed in all treatment groups and the standard group compared to the control group.
Conclusion: Our study demonstrated the potential antidepressant activity of Matricaria chamomilla and Selenium in the experimental model of progesterone-induced postpartum depression in mice. These elements as supplement compounds could be alternatives for antidepressants in postpartum period. It seems that the antidepresent effects of this compounds do not induced by effects on oxidant-antioxidant system and may exert through any other pathway.

Abstract
Background: Spinal cord injury (SCI) is a significant medical and social issue, leading to varying degrees of sensory and motor impairments. Most men experience sexual dysfunction and fertility problems. These issues can be partially attributed to pathophysiological mechanisms, including damage caused by reactive oxygen species (ROS). Targeted antioxidant therapy can significantly reduce oxidative stress and neuro inflammation. This study sought to examine the impact of selenium and astaxanthin on sperm parameters and the recovery of sensory-motor function in rats with spinal cord injury (SCI).
Methods: This experimental study utilized the rat animal model and was carried out at the Neuroscience Research Center Laboratory of Tabriz University of Medical Sciences from December 30, 2022, to November 27, 2023. Fifty adults male Wistar rats were randomly allocated into five groups of ten: control, sham, SCI, selenium-supplemented, and astaxanthin-supplemented. Except for the control and sham groups, spinal cord injury was induced in all other groups. Six weeks after the injury and upon completion of the treatment, the effects of selenium and astaxanthin supplementation on sperm parameters and spinal cord repair were assessed. The Basso, Beattie, and Brenham (BBB) scale was employed to evaluate motor function, while the Von Frey test was utilized to assess sensory status.
Results: A considerable rise in sperm concentration was noted in both the selenium-fed group and the astaxanthin-fed group when compared to the spinal cord injury group (P=0.001). Supplementation with selenium and astaxanthin improved sperm concentration, progressive motility, and viability, bringing these parameters close to control levels (P<0.001). However, neither of these substances had an effect on abnormal sperm morphology (P>0.05). Both selenium and astaxanthin supplementation enhanced the motor and sensory functions of the injured rats (P<0.001), with selenium showing a greater role in promoting repair compared to astaxanthin (P<0.001).
Conclusion: Selenium and astaxanthin supplements improved sperm parameters, except for sperm morphology, and were effective in enhancing motor and sensory functions after spinal cord injury. Selenium was found to be more effective than astaxanthin in promoting spinal cord repair.
