Abstract
Background and Objective: The electromagnetic field producer sets in daily life causes concerns about the adverse effects of such waves on human health. This study was done to evaluate the effect of cell phones microwaves on histologic structures of some visceral organs in rat.
Methods: In this experimental study, 80 immature Wistar male rats with weight of 100-140 gram and 5 to 6 weeks age were randomly allocated into 3 experimental groups and one control group. The experimental rats were exposed to cell phones microwaves 5 hours a day for 1, 2 and 3 months. The control group received no radiation. After the experimental period rats were sacrificed and the appropriate tissues of the lung, heart, liver, brain and pancreas were prepared. Sections in 5 µm thicknesses were stained by hematoxylin and eosin and studied microscopically.
Results: Histological changes including edema, inflammatory cell infiltration and cell degeneration in the lung and mild degeneration and coagulation necrosis of the myocardial cells in the heart were observed. Histopthological examination of the liver revealed dilation of central veins and sinusoids, vacuolization of hepatocytes and mononuclear inflammatory cell infiltration. Limited changes were observed in pancreas and brain. Histological changes were increased in the groups that were exposed longer period of time to radiation.
Conclusion: This study indicated that the harmful effect of cell phones radiation on rat tissues depending on the duration of exposure.

Abstract
Background and Objective: Trauma is the most important causes of lossing effective life in human comunities, and it is the second leading cause of death in Iran. This study was done to determine the pattern of penetrating injuries and intrathoracic organ damage in Gorgan, north of Iran.
Methods: In this descriptive study, data of 107 patients with penetrating injuries whom referred to
5th Azar hospital in Gorgan-Iran during 2016-17 were collected. Age, gender, job, type, location and cause of injury were recorded for eacgh subject.
Results: The mean age of patients was 26.13 years. The most frequent job was related to unemployed group (39.25%). The most freqent causes of trauma were quarrel with 78.5%. The most divice were knife with 66.35%. Lung was the most injured organ with 11.21%. The least damage was to the large vessels with one case (0.93%). The two patients died due to heart and subclavin vessels injuries.
Conclusion: This study showed that injury due to knife was the most prevalent of penetrating trauma in street strife in northern Iran.

Abstract
Background and Objective: Hemoptysis is defined as the expectoration of blood from the lower respiratory tract. Bronchiolitis, bronchogenic carcinoma, and bronchiectasis are the most common causes of hemoptysis in developed countries, while infections caused by Mycobacterium tuberculosis are the most common cause in endemic countries. This study was conducted to determine the frequency of causes of hemoptysis and some related factors.
Methods: This descriptive-analytical study was done on 68 patients (37 men and 31 women, average age 56.85±17.27 years) who were referred to the Shahid Sayyad Shirazi Hospital in Gorgan, north of Iran during 2014-16 with the complaint of hemoptysis. Demographic information, cause of hemoptysis and history of illness or drug abuse were extracted from the patients’ records.
Results: Based on the results, 42.6%, 45.6%, and 17.6% of the patients had a history of smoking, drug abuse, and diabetes, respectively. The most frequent causes of hemoptysis were bronchiectasis (25%), pneumonia (20.6%), tuberculosis, and lung cancer (16.4%). Gender was determined as an independent risk factor for hemoptysis (P<0.05). The most common causes of hemoptysis were bronchiectasis, lung cancer and pneumonia in men, and tuberculosis and bronchiectasis in women. Age, drug abuse, smoking, and diabetes had no significant association with the occurrence of hemoptysis.
Conclusion: Bronchiectasis, tuberculosis, and lung cancer are the main causes of hemoptysis, and gender is an independent risk factor for hemoptysis in the study area.

Abstract
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.
