Background&Objective: Stress in managers will effect and destroy the immune system on mental health. Clinical studies have revealed that, social support is one of the moderating factors of negative effect of stress on immune system. The aim of this research was study the correlation between social support and immune system of high school managers in khozestan province. Materials&Methods: An experimental study was conducted on 360 male and femal managers who were participated. Then randomly two groups (n=80 in each group) of low and high social support were selected. Subjects who suffered from disorders that affected the immune system were excluded. Number of T-helper cells (CD4), T-suppressor cytotoxic cell (CD8), Natural killer cells (CD56+CD16), Complement system (C3,C4,CH50), Immunoglobulin M and G (IgM&IgG), cortisol hormone, Eosinophils, Neutrophils and Lymphocytes were measured. Results: There was a significant positive correlation between social support and CD4, CD4/CD8, NK cell (CD56+CD16), CH50, IgM and Neutrophils. Also there was a significant negative correlation between social support and CD8, cortisol and Eosinophils. There was a significant difference between high and low social support managers in CD4, CD4/CD8, CD8, cortisol, CH50, C4, C3 and Lymphocytes. Conclusion: The results indicated that social support has a positive significant correlation with those immune cells that improve the immune system and has a negative correlation with those immune cells that decerase the immune system. In fact the social support is a moderating factor angainst stress and its negative effects on immune system.

Sports activities are hindered by the lack of clean air in large and industrialized cities, and the countless benefits of exercise are not considered. With the search of the literature, 89094 articles related to air pollution that have been published in SID, PubMed, and Web of Science until December 2021 were found. Ultimately, 80 articles were extracted after selecting the articles and narrowing the search to exercise inflammation and lung tissue. After removing out-of-date articles (not published between 2000 and 2021) and those without full text, 65 articles were included in the review. Based on the review, exposure to air pollution is associated with increased inflammation and decreased cellular immune function, which is characterized by the activation of toll-like receptors and downstream signaling pathways. Regular exercise improves the inflammatory status in different pulmonary diseases. People who exercise in polluted environments are at increased risk of respiratory and cardiovascular diseases due to the elevated amount of pollutants delivered to the lungs. However, studies did not take into account the potential anti-inflammatory effects of exercise training, which could inhibit the pro-inflammatory events induced by air pollution. It seems that regular exercise modifies pulmonary inflammatory responses and body mass and in part decreases the risk of pulmonary diseases.
