Abstract
The effect of Zataria multiflora (Z. multiflora) on serum cytokine, chemokines, and respiratory symptoms in the veterans exposed to sulfur mustard (SM) more than two decades (27-30 years) ago was conducted in 2018. Thirty-four patients were randomly assigned to the placebo group (P, mean age (54.40 ± 5.51)) and two treated groups with Z. multiflora extract 5 and 10 mg/kg/day (Z5 and 10; mean age, 58.50 ± 3.60 and 55.18 ± 4.11, respectively). Serum levels of tumor necrosis factor (TNF-α), monocyte chemotactic protein 1 (MCP-1), vascular endothelial growth factor (VEGF), epidermal growth factor (EGF), forced expiratory volume-one second (FEV1), and respiratory symptoms including chest wheeze (CW), night wheeze (NW), night cough (NC), and cough and wheeze during exercise (ECW) were assessed at the baseline (phase 0), 1 and 2 months after starting treatment (phase I and II, respectively). The value of FEV1 was significantly increased in Z10 in phase I and II compared with that in phase 0 (p < 0.01 for both) and in Z5 in phase II compared with phase I and 0 (p < 0.001for both). All respiratory symptoms significantly decreased in Z5 and 10 in phase I and II compared with those in phase 0 (p < 0.05 to p < 0.001). Serum levels of TNF-α and VEGF were decreased in Z5 and 10 in phase I and II compared with those in phase 0 (p < 0.05 to p < 0.001). Serum levels of MCP-1 and EGF were decreased in Z10 in phase I and II compared with those in phase 0 (p < 0.05 to p < 0.001). The percent change of respiratory symptoms, serum levels of cytokines during the treatment period, was significantly improved in the treated groups compared with that in the placebo group. Two months' of treatment with Z. multiflora improved cytokine levels, respiratory symptom, and FEV1 values in SM-exposed patients.

Abstract
Nitrogen mustard (NM) is a highly toxic alkylating agent. Inhalation exposure can cause acute and chronic lung injury. This study's aims were to develop an in vitro coculture model of mustard-induced airway injury and to identify growth factors contributing to airway pathology. Primary human bronchial epithelial cells cultured with pulmonary endothelial cells were exposed to NM (25, 50, 100, 250, or 500 μM) or PBS (control) for 1 hour. Lactate dehydrogenase (LDH) and transepithelial electrical resistance (TEER) were measured before and 24 h after NM exposure. Fixed cultures were stained for hematoxylin and eosin or live/dead staining. Culture media were analyzed for 11 growth factors. A 1-h vapor exposure to greater than or equal to 50 μM NM increased supernatant LDH, decreased TEER, and caused airway epithelial cell detachment. Endothelial cell death occurred at 500 μM NM. Vascular endothelial growth factor A (VEGF-A) and placental growth factor (PlGF) expression increased in 500 μM NM-exposed cultures compared with PBS-exposed control cultures. NM vapor exposure causes differential cytotoxicity to airway epithelial and endothelial injury in culture. Increased VEGF-A and PlGF expression occurred acutely in airway cocultures. Future studies are required to validate the role of VEGF signaling in mustard-induced airway pathology.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) that includes multiple mechanisms such as inflammation, infection, smoking, hypoxia, and lack of antioxidant response can cause oxidative stress. In our study, we aimed to determine the changes in some oxidative stress [malondialdehyde and glutathione] and some cellular immunity markers (neopterin and TGF-b) in patients diagnosed with COPD and determine the damage to the organism. METHODS While the high-performance liquid chromatography (HPLC) method (Immuchrom kit, Germany) was utilized to determine MDA, GSH and NP levels, the ELISA method was used for TGF-b levels. RESULTS All obtained data regarding each parameter were compared with both COPD and healthy individuals and between parameters. There was a statistically significant difference between the control group of healthy subjects and COPD group in all parameters (p<0.05). A negative and correlation between oxidant MDA and antioxidant GSH parameters was determined (p=-0.394). CONCLUSIONS As a result, it was seen that oxidative balance changed in the patient group and cellular immunity increased. When the obtained data and literature are taken into account, these changes occurring in oxidative balance and cellular immunity are of importance in determining the development in the pathogenesis of COPD, treatment op - tions and their risks for heart disease in advance.

Evaluation of miR-9 and miR-143 expression in urine specimens of sulfur mustard exposed patients. Interdiscip Toxicol 2016; 8:169-74.

Abstract
Sulfur mustard (SM) or mustard gas is a chemical alkylating agent that causes blisters in the skin (blister gas), burns the eyes and causes lung injury. Some major cellular pathways are involved in the damage caused by mustard gas such as NF-κb signaling, TGF-β signaling, WNT pathway, inflammation, DNA repair and apoptosis. MicroRNAs are non-coding small RNAs (19–25 nucleotides) that are involved in the regulation of gene expression and are found in two forms, extracellular and intracellular. Changes in the levels of extracellular microRNAs are directly associated with many diseases, it is thus common to study the level of extracellular microRNAs as a biomarker to determine the pathophysiologic status. In this study, 32 mustard gas injured patients and 32healthy subjects participated. Comparative evaluation of miR-9 and miR-143 expression in urine samples was performed by Real Time PCR and Graph Pad software. The Mann Whitney t-test analysis of data showed that the expression level of miR-143 and miR-9 had a significant decrease in sulfur mustard individuals with the respective p-value of 0.0480 and 0.0272 compared to normal samples, with an imbalance of several above mentioned pathways. It seems that reducing the expression level of these genes has a very important role in the pathogenicity of mustard gas injured patients.

Abstract
Mustard lung is a major pulmonary complication in individuals exposed to sulfur mustard (SM) gas during the Iran-Iraq war. It shares common pathological and clinical features with some chronic inflammatory lung disorders, particularly chronic obstructive pulmonary disease (COPD). Airway remodeling, which is one of the main causes of lung dysfunction and the dominant phenomenon of chronic pulmonary diseases, is seen in the mustard lung. Among all mediators involved in the remodeling process, the transforming growth factor (TGF)-β plays a pivotal role in lung fibrosis and consequently in the airway remodeling. Regarding the high levels of this mediator detected in mustard lung patients, in the present study, we have discussed the possible roles of TGF-β in airway remodeling (including epithelial layer damage, subepithelial fibrosis and angiogenesis). Finally, based on TGF-β targeting, we have reviewed new airway remodeling therapeutic approaches.
