Objective(s): To investigate the protective effect of S-nitrosoglutathione (SNG) pretreatment on acute lung injury (ALI) in septic rats. Materials and Methods: We constructed a rat model of sepsis by cecal ligation and perforation (CLP), and randomly divided into Sham, CLP, and CLP+SNG (0.25 and 0.5 mg/kg) groups. We used H&E; staining an...

objective: free radicals generated by ionizing radiation attack various cellular components such as lipids. the lung is a very radiosensitive organ and its damage is a doselimiting factor in radiotherapy treatments. melatonin (mlt), the major product of the pineal gland acts as a radioprotective agent. this study aims to investigate the radioprotective effects of mlt on malondialdehyde (mda) le...

BACKGROUND Mechanical ventilation causes ventilator-induced lung injury in animals and humans. Mitogen-activated protein kinases have been implicated in ventilator-induced lung injury though their functional significance remains incomplete. We characterize the role of p38 mitogen-activated protein kinase/mitogen activated protein kinase kinase-3 and c-Jun-NH(2)-terminal kinase-1 in ventilator-i...

TOPIC: Diffuse Lung Disease TYPE: Fellow Case Reports INTRODUCTION: Tacrolimus is commonly used for immunosuppression after solid-organ transplant to prevent organ rejection. has a wide range of adverse effects, including secondary infections, renal failure, hyperglycemia, and weight gain, when in combination with other medications. However, association diffuse lung disease quite rare. We prese...
