asthma is a chronic inflammatory disease of the airway with extensive airway remodeling. the ethical issues associated with the studies in asthmatic patients, required development of animal model of asthma. animal models of asthma can provide valuable information on several features of asthma pathogenesis and treatment. although these models cannot carry out all clinical features, they are valu...

human airway is generally destructed by inhaled factors and is the barrier to the external environment and has a crucial role in protection of the internal homeostasis of the lung. sulfur mustard (sm) is a chemical warfare that capable of producing severe chemical injuries primarily in the lungs. trefoil factor family (tffs) plays major roles in epithelial repair and homeostasis, particularly i...

micrornas participate in the regulation of asthma, the goal of this study is to summarize recent researches on the roles of micrornas in the pathogenesis of asthma. a review of the english medical literatures was conducted by searching pubmed for studies concerning asthma and micrornas. the results of the present study indicate that micrornas play important roles in regulating asthma immune res...

the widespread use of sulfur mustard  (sm) as a chemical warfare agent in the  past century has proved its long-lasting toxic effects. despite a lot of research over the past decades on iranian veterans, there are still major gaps in the sm literature. transforming growth  factor  (tgf-β),  a  cytokine  that  affects  many  different  cell processes,  has  an important role in the lungs of pati...

airway remodelling is characterized by the thickening and reorganization of the airways seen in mustard  lung patients. mustard lung is the  general description  for  the  chronic obstructive  pulmonary  disease induced  by  sulfur  mustard(sm). pulmonary  disease was diagnosed as the most important  disorder in individuals that had been exposed to sulfur mustard. sulfur mustard is a chemical w...

hedera helix  is widely used to treat bronchial asthma for many years. however, effects of this herb on lung histopathology is still far from clear. we aimed to determine the effect of oral administration of hedera helix on lung histopathology in a murine model of chronic asthma. balb/c  mice  were  divided  into  four  groups;   i  (placebo),  ii  (hedera  helix), iii (dexamethasone) and iv (c...

objective: asthma is an airway complex disease defined by reversible airway narrowing and obstruction, chronic airway inflammation, airway hyperresponsiveness, and tissue remodeling. the purpose of this study was to determine the effect of brassica napus l. (b. napus) on airway pathologic changes in a rat model of asthma. materials and methods: twenty-four rats were divided into 4 groups: contr...

BACKGROUND Apart from airway inflammation, airway remodeling is one of the main pathological features of asthma. However, it remains unclear when airway remodeling starts in children and whether it could be a potential therapeutic target in asthma. DATA SOURCES We have reviewed the recent literature regarding structural changes after airway remodeling, the relationship between airway inflamma...

BACKGROUND Airway remodeling is a repair process that occurs after injury resulting in increased airway hyper-responsiveness in asthma. Thymic stromal lymphopoietin (TSLP), a vital cytokine, plays a critical role in orchestrating, perpetuating and amplifying the inflammatory response in asthma. TSLP is also a critical factor in airway remodeling in asthma. OBJECTIVES To examine the role of TS...

according to significant improvements in the tissue engineering field over the past several years, lung tissue cells have recently attracted more attention due to the high prevalence and diversity in related diseases. however, selection of an appropriate cell type, screening of suitable conditions for growth and proliferation, as well as subsequent implantation into the body to repair and regen...
