A 37 - year- old man came to the hospital with a history of penetrating thoracoabdominal trauma due to gunshot wound in 10 days before. He underwent laparatomy and hepatorrhaphy in that time and right sided chest tube was inserted. Chest CT scan revealed metallic foreign body in lung tissue due to bullet burst. Right thoracotomy was performed and metallic foreign body extracted from lung tissue
Objective(s): Obstructive sleep apnea (OSA) is confirmed to cause lesions in multiple organs, especially in the lung tissue. Tempol is an antioxidant that has been reported to restrain inflammation and oxidative stress, with its role in OSA-induced lung injury being unclear. This study aimed to investigate the beneficial effect of tempol on chronic intermittent hypoxia (IH)-induced lung injury....
Introduction: Nanotechnology deals with structures that their dimensions are approximately between 1 to 100 nanometers. Research has shown that the composition, shape and different sizes of nanosilver make the features that possess different toxic effects compared with the chemicals with same but larger composition (microsilver). Nanosilver is associated with cell division, oxidative stress, an...
In radiation therapy of lung tumors, respiratory motion causes target moving, so a larger margin is needed to cover the CTV. With the margin increasing, a larger volume of normal tissue will be exposed to high-dose. In this study, dosimetric parameters of normal lung tissue were compared between gated and conventional radiotherapy (RT), using the NCAT digital phantom. Different series of CT im...
Introduction: Internal exposure to radon gas progeny can lead to serious biologic damages to the lung tissue. The aim of this study was to evaluate the absorbed dose by lung tissue due to the exposure from short-lived radioactive products of radon (222Rn) decay using Monte Carlo simulation. Material and Methods: A lung equivalent p...
Cellular and tissue activities highly depend on environmental pH. Murine lung tissue, when cultured properly in-vitro, is a potent producer of hematopoietic growth factors. We have studied the effect of pH on the production of hematopoietic growth factors and protein synthesis by the murine lung in-vitro. Various concentrations of NaHC03 were used to adjust the pH of the culture medium unde...
gastroesophageal reflux disease (gerd) is defined with clinical symptoms of heart burning and regurgitation. it may be associated with external esophageal symptoms such as chronic cough, asthma, laryngitis, chronic lung disease, sinusitis and pulmonary fibrosis. in the present study, rats with chronic aspiration of gastroduodenal contentswere studied for cellular phenotypes and cytokine c...
Purpose: The effects of Amiodarone on lung tissue and morphologic changes of alveolar cells. Materials and Methods: in this study, we used 21 mature male rabbits and they were divided into control and two experimental groups. Daily 80 mg/kg amiodarone was injected intra peritoneally to the experimental animals for one or two weeks. The control group received normal saline the same dose as amio...
