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
Most mortality and morbidity following exposure to vesicants such as sulfur mustard is due to pulmonary toxicity. Acute injury is characterized by epithelial detachment and necrosis in the pharynx, trachea and bronchioles, while long-term consequences include fibrosis and, in some instances, cancer. Current therapies to treat mustard poisoning are primarily palliative and do not target underlying pathophysiologic mechanisms. New knowledge about vesicant-induced pulmonary disease pathogenesis has led to the identification of potentially efficacious strategies to reduce injury by targeting inflammatory cells and mediators including reactive oxygen and nitrogen species, proteases and proinflammatory/cytotoxic cytokines. Therapeutics under investigation include corticosteroids, N-acetyl cysteine, which has both mucolytic and antioxidant properties, inducible nitric oxide synthase inhibitors, liposomes containing superoxide dismutase, catalase, and/or tocopherols, protease inhibitors, and cytokine antagonists such as anti-tumor necrosis factor (TNF)-α antibody and pentoxifylline. Antifibrotic and fibrinolytic treatments may also prove beneficial in ameliorating airway obstruction and lung remodeling. More speculative approaches include inhibitors of transient receptor potential channels, which regulate pulmonary epithelial cell membrane permeability, non-coding RNAs and mesenchymal stem cells. As mustards represent high priority chemical threat agents, identification of effective therapeutics for mitigating toxicity is highly significant.

Abstract
Pulmonary complications of exposure to sulfur mustard (SM) gas range from no effect or mild symptoms to severe bronchial stenosis. In the present study, the protective effect of vitamin E on the lung inflammation of SM-exposed guinea pigs was examined. Guinea pigs ( n = 5 for each group) were exposed to ethanol (control group), 40 mg/m3 inhaled SM (SME group), SME treated with vitamin E (SME + E), SME treated with dexamethasone (SME + D), and SME treated with both treatments (SME + E + D). Pathological evaluation of the lung was done 14 days postexposure. The epithelial desquamation of trachea and other pathologic changes in the lung of the SME group were significantly higher than those in the control group. Furthermore, the pathological changes of trachea and lung in the SME + E and SME + E + D groups were significantly improved compared with those of SME group. In addition, the pathological changes of trachea and lung of SME + E and SME + E + D animals were significantly less than those of SME + D group.

Abstract
CONTEXT Previous research has found relationships between sulfur mustard (SM) toxicity and its adverse effects. OBJECTIVE SM is highly toxic to the respiratory system, leading to hacking cough, rhinorrheachest tightness, acute pharyngitis and laryngitis, chronic bronchitis and lung fibrosis. In this review, based on the scientific literature, we provide an updated summary of information on SM exposures and their differences with asthma and COPD. METHOD Information of this review was obtained by searching Medline/PubMed, ScienceDirect, Scopus, Google Scholar, ISI Web of Knowledge and Chemical Abstracts. RESULTS SM exposure can decrease pulmonary function tests (PFTs) values. In addition, inflammatory cell accumulation in the respiratory tract and increased expression of some pro-inflammatory cytokines including tumor necrosis factor-α (TNFα), IL-1a, IL-1β, and reactive oxygen radicals due to SM exposure have been shown. Matrix metalloproteinase (MMP) which degrade extracellular matrix proteins, contributing to inflammatory cell recruitment, tissue injury and fibrosis are also up-regulated in the lung after SM exposure. In the lung, SM exposure also can cause serious pathological changes including airway inflammation, parenchymal tissue destruction and airway obstruction which can lead to asthma or chronic obstructive pulmonary disease (COPD). Following SM poisoning, DNA damage, apoptosis and autophagy are observed in the lung along with the increased expression of activated caspases and DNA repair enzymes. CONCLUSION In the present article, respiratory symptoms, changes in PFTs, lung pathology and lung inflammation due to SM exposure and the similarities and differences between them and those observed in asthma and COPD were reviewed.

Abstract
CONTEXT Sulfur mustard (SM), with an old manufacturing history still remains as potential threat due to easy production and extensive effects. OBJECTIVES Increasing studies on SM indicates the interest of researchers to this subject. Almost all human body organs are at risk for complications of SM. This study offers organ-by-organ information on the effects of SM in animals and humans. METHODS The data sources were literature reviews since 1919 as well as our studies during the Iraq-Iran war. The search items were SM and its all other nomenclatures in relation to, in vivo, in vitro, humans, animals, eye, ocular, ophthalmic, lungs, pulmonary, skin, cutaneous, organs and systemic. Amongst more than 1890 SM-related articles, 257 more relevant clinicopathologic papers were selected for this review. RESULTS SM induces a vast range of damages in nearly all organs. Acute SM intoxication warrants immediate approach. Among chronic lesions, delayed keratitis and blindness, bronchiolitis obliterans and respiratory distress, skin pruritus, dryness and cancers are the most commonly observed clinical sequelae. CONCLUSION Ocular involvements in a number of patients progress toward a severe, rapid onset form of keratitis. Progressive deterioration of respiratory tract leads to "mustard lung". Skin problems continue as chronic frustrating pruritus on old scars with susceptibility to skin cancers. Due to the multiple acute and chronic morbidities created by SM exposure, uses of multiple drugs by several routes of administrations are warranted.

Abstract
Pulmonary complications due to mustard gas exposure range from no effect to severe bronchial stenosis. Pulmonary function tests (PFTs) and respiratory symptoms in chemical war victims were studied 23–25 years after exposure to sulfur mustard (SM). Respiratory symptoms were evaluated in a sample of 142 chemical war victims and 120 control subjects with similar age from the general population using a questionnaire including questions on respiratory symptoms in the past year. PFT values were also measured in chemical war victims before and 15 min after the inhalation of 200 µg salbutamol and baseline PFT in controls. All chemical war victims (100%) reported respiratory symptoms. Wheezing (66.19%), cough (64.78%), and chest tightness (54.4%) were the most common symptoms and only 15.5% of chemical war victims reported sputum ( p < 0.01 for sputum and p < 0.001 for other symptoms compared with control group). In addition, 49.3% of chemical war victims had wheeze in chest examination, which were significantly higher than control group ( p < 0.001). The severity of respiratory symptoms was also significantly higher than control subjects ( p < 0.05 for sputum and p < 0.001 for other symptoms). All the PFT values were also significantly lower in chemical war victims than that in control subjects ( p < 0.001 for all cases). In addition, all the PFT values improved significantly after the inhalation of 200 µg salbutamol ( p < 0.05– p < 0.001). These results showed that chemical war victims, 23–25 years after exposure to chemical warfare have higher frequencies and severity of respiratory symptoms. PFT values were also significantly reduced among chemical war victims, which showed reversibility due to the inhalation of 200 µg salbutamol.

Abstract
Iranian soldiers were attacked with chemical bombs, rockets and artillery shells 387 times during the 8-years war by Iraq (1980-1988). More than 1,000 tons of sulfur mustard gas was used in the battlefields by the Iraqis against Iranian people. A high rate of morbidities occurred as the result of these attacks. This study aimed to evaluate the delayed toxic effects of sulfur mustard gas on Iranian victims. During a systematic search, a total of 193 (109 more relevant to the main aim) articles on sulfur mustard gas were reviewed using known international and national databases. No special evaluation was conducted on the quality of the articles and their publication in accredited journals was considered sufficient. High rate of morbidities as the result of chemical attacks by sulfur mustard among Iranian people occurred. Iranian researchers found a numerous late complications among the victims which we be listed as wide range of respiratory, ocular, dermatological, psychological, hematological, immunological, gastrointestinal and endocrine complications, all influenced the quality of life of exposed victims. The mortality rate due to this agent was 3%. Although, mortality rate induced by sulfur mustard among Iranian people was low, variety and chronicity of toxic effects and complications of this chemical agent were dramatic.

Abstract
UNLABELLED ETHNOMEDICAL RELEVANCE: The anti-inflammatory activity of both systemic and local administrations of essential oil from Nigella sativa L. has been shown. AIM OF THE STUDY Therefore, the effect of Nigella sativa on tracheal responsiveness (TR) and lung inflammation of sulfur mustard (SM) exposed guinea pigs was examined. MATERIALS AND METHODS Guinea pigs were exposed to diluent solution (control group), inhaled SM (SME group), SME treated with Nigella sativa (SME+N), SME treated with dexamethasone (SME+D) and SME treated with both drugs (SME+N+D), (n=7 for each group). TR to methacholine, total white blood cell (WBC) and differential WBC count of lung lavage, and serum cytokines were measured 14 days post-exposure. RESULTS The values of TR, eosinophil, monocyte, lymphocyte, interleukine-4 (IL-4) and interferon gamma (IFN-γ) of SME group were significantly higher than those of controls (p<0.05 to p<0.001). The TR in SME+N, SME+D and SME+N+D was significantly lower compared to that of SME group (p<0.01 for all cases). The percentage of eosinophil in SME+D, and the percentage of monocyte in SME+N+D (p<0.05 to p<0.01) were significantly lower than those in SME group. The neutrophil number was decreased in SME+N and SME+N+D groups compared to SME animals (p<0.05 to p<0.01). IL-4 levels in serum of SME+N (p<0.01), SME+D (p<0.05), SME+N+D (p<0.01) and IFN-γ in SME+N (p<0.05) were greater than those in SME animals. CONCLUSIONS These results showed a preventive effect of Nigella sativa on TR and lung inflammation of SM exposed guinea pigs.

Abstract
Sulfur mustard (SM) is highly toxic to the lung inducing both acute and chronic effects including upper and lower obstructive disease, airway inflammation, and acute respiratory distress syndrome, and with time, tracheobronchial stenosis, bronchitis, and bronchiolitis obliterans. Thus it is essential to identify effective strategies to mitigate the toxicity of SM and related vesicants. Studies in animals and in cell culture models have identified key mechanistic pathways mediating their toxicity, which may be relevant targets for the development of countermeasures. For example, following SM poisoning, DNA damage, apoptosis, and autophagy are observed in the lung, along with increased expression of activated caspases and DNA repair enzymes, biochemical markers of these activities. This is associated with inflammatory cell accumulation in the respiratory tract and increased expression of tumor necrosis factor-α and other proinflammatory cytokines, as well as reactive oxygen and nitrogen species. Matrix metalloproteinases are also upregulated in the lung after SM exposure, which are thought to contribute to the detachment of epithelial cells from basement membranes and disruption of the pulmonary epithelial barrier. Findings that production of inflammatory mediators correlates directly with altered lung function suggests that they play a key role in toxicity. In this regard, specific therapeutic interventions currently under investigation include anti-inflammatory agents (e.g., steroids), antioxidants (e.g., tocopherols, melatonin, N-acetylcysteine, nitric oxide synthase inhibitors), protease inhibitors (e.g., doxycycline, aprotinin, ilomastat), surfactant replacement, and bronchodilators. Effective treatments may depend on the extent of lung injury and require a multi-faceted pharmacological approach.

Abstract
We examined the role of two regimens of combination inhaler therapy on amount of reversibility of chronic lung complications in mustard gas exposed patients. In a phase III, prospective, randomized clinical trial, 105 participants received either combination form of fluticasone propionate and salmetrol, 500/100 microg daily (group 1; n = 52) or beclomethasone, 1000 microg daily, and salbutamol inhaler, 800 microg daily (group 2; n = 53) for 12 wk. Pulmonary function test (PFT) indices and respiratory symptoms (including dyspnea, night awakening due to dyspnea and cough) were assessed at baseline and in each visit. Thirty-six patients in group 1 and 30 patients in group 2 completed study course. Both medication regimes increased pretreatment forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), FEV1/FVC%, and peak expiratory force (PEF) by the end of 12 wk. It seems that these improvements are more constant in group 1 than in group 2. Reversibility, that is, 10% increase of FEV1 in the second month was seen for 27% of patients in the group 1 and for 7% in the group 2. VAS scores have decreased in two groups during treatment period (p = .003) and after follow-up period it remained sustained in group 1 alone. Inhaled corticosteroids and long-acting beta 2-agonists are effective in treatment of patients with chronic bronchiolitis following exposure to sulfur mustard. However, a medium dose of fluticasone/salmeterol has the same effect on the airways reversibility, rather than a very high dose of beclomethasone with only the short-acting beta-agonist.

Abstract
BACKGROUND It has been demonstrated that the phenotypic modulation of airway smooth muscle cells (ASMCs) is important to the pathogenesis of airway remodeling in chronic asthma. The extracellular signal-regulated kinase 1/2 (ERK1/2) signaling pathway is one of the most important transduction pathways involved in the process of asthma; however, its role in the phenotypic transition of ASMCs remains unclear. OBJECTIVES To examine the role of ERK1/2 in the phenotypic modulation of ASMCs in the rat model of chronic asthma. METHODS Bronchial smooth muscle strips were cultured in vitro in the presence of the ERK1/2 agonist epidermal growth factor or/and the MEK inhibitor PD98059. The phenotype of ASMCs was determined by observing these cells under an electron microscope and analyzing expression of phenotypic markers (smooth muscle alpha-actin for the contractile phenotype and osteopontin for the synthetic) by using Western blot and reverse-transcriptase polymerase chain reaction, respectively. RESULTS The phenotype of the ASMCs from the chronic asthmatic rats changed from the contractile type to the synthetic type with synthetic organelles abundantly gathered around the nucleus and altered expression of phenotypic markers. ERK1/2 was strongly expressed in the ASMCs of the chronic asthmatic rats and its activation by epidermal growth factor excessively promoted the synthetic function of ASMCs; the MEK inhibitor PD98059, however, reversed this phenotypic change in the ASMCs. CONCLUSIONS Our results reveal a key role of the ERK1/2 signaling pathway in the phenotypic modulation of ASMCs in chronic asthmatic rats, indicating that specific inhibition of ERK1/2 in ASMCs may be therapeutically valuable in the control of airway remodeling in chronic asthma.

Abstract
Mustard gas (HD) was a widely used chemical warfare agent during World War I and more recently in the Iraq-Iran war (1980-1988). To date, dramatically, 45,000 Iranians are suffering from late respiratory complications due to MG exposure. This review covers two decades of researches on latent pulmonary effects of MG. Findings from clinical manifestations, pathologic examinations, laboratory data, lung function tests, and radiological evaluations are reviewed. From this review we are able to provide a suitable practical plan for workup and management of patients in this setting.
