results histopathologically, a decrease (statistically not significant) in the thickening of alveolar or bronchial wall, formation of fibrous bands, and superimposed collagen were noted in the animals in group b as compared to the animals in group a. conclusion in this experimental study, administration of gla one hour before thoracic irradiation may be a protective agent against radiation-indu...

introduction: pulmonary involvement secondary to systemic sclerosis (ssc) is the major cause of morbidity and mortality in ssc patients. we designed this study to determine the correlation of important lung function parameters with lung high resolution ct (hrct) scan findings.materials and methods: thirty–two consecutive diffuse ssc patients with pulmonary fibrosis were enrolled in this cross-s...

background: vitamin d, especially its most active metabolite 1,25-dihydroxyvitamin d₃(vit d) is essential in regulating a wide variety of biologic processes, such as regulating mesangial cell activation. the objective of this study was to assess the histopathological changes of effectiveness of vit d as a protective agent against radiation induced lung injury. materials and methods: eighteen wi...

Background: Bleomycin-induced lung fibrosis has been accepted as an animal model for fibrosis in rats. The aim of this study was to evaluate the effects of saffron aqueous extract on this disorder paving the way for more investigation in treating idiopathic pulmonary fibrosis in human.  Methods: Male Wistar rats (250–300 gr) were instilled a single dose of bleomycin (5 mg/kg) via in...

Introduction: Pulmonary involvement secondary to Systemic Sclerosis (SSc) is the major cause of morbidity and mortality in SSc patients. We designed this study to determine the correlation of important lung function parameters with lung High Resolution CT (HRCT) scan findings. Materials and Methods: Thirty–two consecutive diffuse SSc patients with pulmonary fibrosis were enrolled in this cross...

Background & Aims: Idiopathic pulmonary fibrosis (IPF) is a chronic diffuse interstitial lung disease, which has symptoms such as coughing and shortness of breath. The average survival duration in these patients is estimated as 3 years after the onset of symptoms. Today, the therapeutic approach used in IPF cases is the usage of chemical or herbal antioxidants in order to elim...

Combined therapy with clarithromycin (CLTR) and N–acetyl cysteine (NAC) may be useful in diseases with impaired oxidant-antioxidant balance, fibroblast proliferation, and collagen deposition such as pulmonary fibrosis. Activated inflammatory cells which accumulate in the lower airways may release increased amounts of reactive oxygen species (ROS) when accompanied with a deficiency in glut...

introduction: idiopathic pulmonary fibrosis (ipf) is a relentlessly progressive and usually fatal lung disease of unknown etiology for which no effective treatments currently exist. in the adults type i and ii pneumocytes, forms components of the alveolar epithelial cells. in this study, we investigated the effect of thalidomide on the alveolar epithelial cells (type i and ii pneumocytes) in th...

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...

apoptosis has a critical role in the pathogenesis of bleomycin induced-pulmonary fibrosis. the severity of fibrosis varies among different strains of mice. recent studies have indicated that expression of apoptotic regulatory genes may be specific in different cell types in various strains. in this study, bleomycin-induced pulmonary apoptosis in nmri albino mice were compared with c57bl/6 black...
