Abstract Aims: To investigate the effect of Myrtenol, the active ingredient of Myrtle, on the oxidant and anti-oxidant indices and cytokines in the allergic asthma. Methods: Allergic asthma was induced by ovalbumin (OVA) sensitization and inhalation in four groups of rats; Control, Asthma, Asthma+Dexamethasone and Asthma+Myrtenol. Myrtenol (50mg/kg) or Dexamethasone (2.5mg/kg) was a...
Background & objectives: Paraquat is a toxic herbicide that is widely used in many countries. Paraquat selectively accumulates in the lung tissue and leads to severe pulmonary injury through the oxidative and inflammatory processes. The plant Rosa canina L. has been used for long years as an herbal medicine throughout the world. Rosa canina L. is a member of Rosacea family and shows therapeut...

signaling amp-activated protein kinase (ampk), an energy sensing enzyme, has been implicated in controlling inflammation. in this study we investigated whether activation of ampk by metformin could protect the lung from lipopolysaccharide (lps)-induced acute injury by inhibitingng tlr4 pathway. male wistar rats were randomly divided into 3 groups (n=6): control group received normal saline (0.5...
Unlike proton therapy, conventional radiation therapy directs X-rays not only at the tumor but also unavoidably at nearby healthy tissue. Protons deliver radiation to tumor tissue while the healthy structures will be spared during proton therapy. When protons travel through matter, secondary particles like neutrons and photons are produced. It is believed that the secondary dose can lead to sec...
Effect of Cerium Oxide Nanoparticles on Oxidative Stress Biomarkers in Rats’ Kidney, Lung, and Serum
Background: The present study aimed to evaluate the effects of different concentrations of cerium oxide nanoparticles (CONPs) on the oxidative stress (OS) status in kidney, lung, and serum of rats. Methods: Male Wistar Rats were treated intraperitoneally with 15, 30, and 60 mg/kg/day of CONPs. The biochemical parameters, including total antioxidant capacity (TAC), total thiol group (TTG), malon...
Background & Aims: Sulfur mustard (SM) is a potent chemical vesicant warfare agent that remains a significant military and civilian threat. Inhalation of SM gas causes airway and bronchioles inflammation and injury to epithelial tissue of the lung. Hexamethylenetetramine (HMT) has been shown to protect human lung cells against SM toxicity and is effective against phosgene toxicity. The aim of...
Introduction: This study investigates to what extent the computed dose received by lung tissue in a commercially available treatment planning system (TPS) for 192Ir high-dose-rate breast brachytherapy is accurate in view of tissue inhomogeneities and presence of ribs. Materials and Methods: A CT scan of the breast was used to construct a patient-equivalent phantom in the clinical treatment plan...
Aims: Mustard gas is an alkalizing substance that can lead to damage to DNA and intracellular enzymes. The aim of this study was to investigate the expression of CXCL10 in chemically-injured veterans’ lung tissue. Materials & Methods: This case-control study was done on 16 lung paraffin blocks of individuals exposed to mustard gas and 7 lungs paraffin blocks not-exposed people as...
Background and Objective: The available information in relation to the effect of high-intensity interval training on lung structural changes are limited. The aim of this study was to evaluate the effect of a high-intensity interval training on structural changes in lung parenchymal and non-parenchymal tissue in male Wistar rats. Materials and Methods: Samples of this study were 12 male W...
