Abstract
Background and Aim: Obstructive sleep apnea (OSA) is one of the most common sleep disorders that, despite the high prevalence, most people are unaware of it. The reason for this disorder is obstruction of the respiratory tract, which reduces blood oxygen as a result of frequent waking during the night. In this study, the status of antioxidant defense was considered as one of the most important mechanisms involved in preventing the consequences of this complication.
Materials and Methods: The 35 subjects of OSA were selected and categorized according to the apnea-hypopnea index (AHI) in two groups: Mild OSA (n=17) and severe OSA (n=18). The fasting blood samples were taken in order to evaluate the antioxidant defense status of the glutathione peroxidase activity (GPx) and glutathione (GSH) content.
Results: The results showed the mean values for GPx in patients with mild and severe apnea were 36.6±2.2 and 35.3±3.7 (u/gHb), respectively. Also, the mean values for GSH content in patients with mild and severe apnea were 0.54±0.1 and 0.68±0.1 µM, respectively that showed a 23% increase (P˂0.05) in severe apnea patients.
Conclusion: There was no significant difference in the GPx activity of mild apnea, however, patients with severe apnea showed a significant increase in GSH levels compared to mild apnea (P<0.05), which may indicate a long-term response to oxidative stress alters gene expression and increases the level of these biomarkers in a long time.

Abstract
Background and Aim: Iron deficiency is one of the most common nutritional disorders in the world, and it may affect the metabolism and function of a number of proteins, including the level of thyroid hormones. As such, fluctuations in the level of thyroid hormones may also affect the body's iron status. The present study aimed to evaluate the relationship between thyroid hormones and the status of iron stores.
Materials and Methods: The study populations included referral patients to laboratory of Shourideh clinic in Mashhad, Iran. Fe, Ferritin, TIBC (total iron-binding capacity), TSH, T4, T3, and CRP tests were performed with a physician's request. The target sample size was a total of 420 patients including 287 women and 133 men with an average age of 41.5 years. TSH and Ferritin test were measured by Elisa method, Fe and TIBC were measured by automated method.
Results: The results showed no significant relationship between the body's iron status and thyroid hormones level (P˃0.05). Interestingly, in subjects with lower iron level, TSH was at the highest level and T4 was at the lowest level. However, no positive relationship was found between iron status and T3 level.
Conclusion: Although, there was no significant relationship between iron status and thyroid hormones level in the present study, it seems that the fluctuations of each of them may affect somehow the other.
