introduction drug-induced liver injury is a frequent cause of hepatic dysfunction. several drugs have been identified to cause autoimmune hepatitis (aih). environmental chemicals are capable of triggering a certain degree of liver injury. however, toxin induced aih is rare. conclusions chronic (long-term) exposures to dichlorvos can lead to aih. a detailed inquiry of medical history and liver b...

conclusions in conclusion, we have shown that vitamin c administration provides protection against csa-induced injury in rat liver function and may have hepatoprotective role in the patients experiencing csa treatment. background cyclosporine a (csa) is an important immunosuppressive agent; however, its clinical use is limited by several side effects such as hepatotoxicity. vitamin c (ascorbic ...

RATIONALE Human data suggest that the incidence of acute lung injury is reduced in patients with type II diabetes mellitus. However, the mechanisms by which diabetes confers protection from lung injury are unknown. OBJECTIVES To determine whether leptin resistance, which is seen in humans with diabetes, protects mice from hyperoxic lung injury. METHODS Wild-type (leptin responsive) and db/d...

BACKGROUND Positive-pressure mechanical ventilation is an essential therapeutic intervention, yet it causes the clinical syndrome known as ventilator-induced lung injury. Various lung protective mechanical ventilation strategies have attempted to reduce or prevent ventilator-induced lung injury but few modalities have proven effective. A model that isolates the contribution of mechanical ventil...

Hyperoxic lung injury is a major concern in critically ill patients who receive high concentrations of oxygen to treat lung diseases. Successful abrogation of hyperoxic lung injury would have a huge impact on respiratory and critical care medicine. Hydrogen can be administered as a therapeutic medical gas. We recently demonstrated that inhaled hydrogen reduced transplant-induced lung injury and...

BACKGROUND Injurious non-microbial factors released from the stressed gut during shocked states contribute to the development of acute lung injury (ALI) and multiple organ dysfunction syndrome (MODS). Since Toll-like receptors (TLR) act as sensors of tissue injury as well as microbial invasion and TLR4 signaling occurs in both sepsis and noninfectious models of ischemia/reperfusion (I/R) injury...

BACKGROUND Leptospiral glycolipoprotein (GLP) is a potent and specific Na/K-ATPase inhibitor. Severe pulmonary form of leptospirosis is characterized by edema, inflammation and intra-alveolar hemorrhage having a dismal prognosis. Resolution of edema and inflammation determines the outcome of lung injury. Na/K-ATPase activity is responsible for edema clearance. This enzyme works as a cell recept...

Pulmonary dysfunction is one of the most frequent complications associated with cardiopulmonary bypass (CPB). Multiple factors, including the contact of blood with the artificial surface of the CPB circuit, ischemia‑reperfusion and lung ventilator arrest elicit inflammatory reactions, consequently resulting in CPB‑induced lung injury. The proinflammatory cytokine tumor necrosis factor‑α (TNF‑α)...

INTRODUCTION Nuclear factor (NF)-κB is central to the pathogenesis of inflammation in acute lung injury, but also to inflammation resolution and repair. We wished to determine whether overexpression of the NF-κB inhibitor IκBα could modulate the severity of acute and prolonged pneumonia-induced lung injury in a series of prospective randomized animal studies. METHODS Adult male Sprague-Dawley...

The mechanisms of susceptibility to particle-induced lung injury are not clearly understood. To evaluate the contribution of genetic background to pulmonary pathogenesis, we compared the lung injury responses to residual oil fly ash (ROFA) in inbred mouse strains and calculated heritability estimates. Significant interstrain (genetic) variation was observed in ROFA-induced lung inflammation and...
