Rapid repair of vascular injury is an important prognostic factor for electrical burns. This repair is achieved mainly via stromal cell-derived factor (SDF)-1α promoting the mobilization, chemotaxis, homing, and targeted differentiation of bone marrow mesenchymal stem cells (BMSCs) into endothelial cells. Forming a concentration gradient from the site of local damage in the circulation is essen...

Factors in plasma and platelets do not fully account for the proliferation of smooth muscle cells in vascular injury, implying that additional factors are involved. Recently, we and others have observed that vascular injury regulates basic fibroblast growth factor, suggesting a further role for this pleiotropic factor. We report here that injury of rat arteries leads to an increase in fibroblas...

We examined the relationship between neutrophil [polymorphonuclear leukocyte (PMN)] influx and lung vascular injury in response to Escherichia coli pneumonia. We assessed lung tissue PMN uptake by measuring myeloperoxidase and transvascular PMN migration by determining PMN counts in lung interstitium and bronchoalveolar lavage fluid (BALF) in mice challenged intratracheally with E. coli. Lung v...

BACKGROUND Blood vessel trauma leading to hemorrhage or ischemia presents a significant cause of morbidity and mortality after battlefield injury. The objective of this study is to characterize the epidemiology of vascular injury in the wars of Iraq and Afghanistan, including categorization of anatomic patterns, mechanism, and management of casualties. METHODS The Joint Theater Trauma Registr...

Context: Vascular dementia (VaD) is the second most common type of after Alzheimer’s disease worldwide. a neurodegenerative disorder characterized by gradual cognitive impairment. Ischemic and hemorrhagic strokes result in VaD, markedly distributing cerebral blood flow decreasing patients’ memory performance. Due to their high energy demands, neurons are more sensitive cellular architecture cha...

PURPOSE Retinal ischemia/reperfusion (I/R) injury results in the generation of reactive oxygen species (ROS). The aim of this study was to investigate whether delivery of the manganese superoxide dismutase gene (SOD2) or the catalase gene (CAT) could rescue the retinal vascular damage induced by I/R in mice. METHODS I/R injury to the retina was induced in mice by elevating intraocular pressur...

Scapulothoracic dissociation is the result of severe blunt trauma or sudden forceful traction applied to the shoulder, simulating a traumatic forequarter amputation but with sparing of the skin. This grievous injury results in injury at three levels: neural, vascular and musculoskeletal. Since the neural damage cannot be ascertained in the acute stage of this injury, wheras the vascular injury ...

Complications arising from lumbar intervertebral disc surgery are rare but fatal. Major vascular injury is one complication that may end in death unless it is diagnosed and treated immediately. Herein we report an abdominal aortic injury due to L3-L4 intervertebral disc surgery that was treated successfully and discuss it in light of current literature. Diagnosis and treatment of an abdominal a...

Angiotensin II (Ang II) promotes growth of vascular smooth muscle cells in vitro. Consistent with this, Ang II enhances neointimal proliferation in vivo after vascular injury, while angiotensin converting enzyme (ACE) inhibitors attenuate this process. Since tissue ACE plays a key role in the control of local Ang II production, we examined whether vascular injury resulted in an increase in vasc...

Chronic pulmonary hypertension is a serious complication of a number of chronic lung and heart diseases. In addition to vasoconstriction, its pathogenesis includes injury to the peripheral pulmonary arteries leading to their structural remodeling. Increased pulmonary vascular synthesis of an endogenous vasodilator, nitric oxide (NO), opposes excessive increases of intravascular pressure during ...
