The purpose of the work was to study the ability of the NOS inhibitor T1023 to prevent late radiation injuries. Methods: the effects of T1023 (75 mg / kg, once i.p. 30 minutes before the irradiation) on the development of post-radiation pulmonitis and pneumofibrosis in rats with thoracic exposure to g-radiation at a dose of 12.5 Gy were studied histopathologically and morphometrically. The results of the studies showed that there wasn’t a significant objective effect of T1023 on the development of early radiation-induced lung injuries (9 weeks after irradiation). But it prevented late radiatio

Abstract The USA has experienced one large-scale nuclear incident in its history. Lessons learned during the Three-Mile Island nuclear accident provided government planners with insight into property damage resulting from a low-level release of radiation, and an awareness concerning how to prepare for future occurrences. However, if there is an incident resulting from detonation of an improvised nuclear device or state-sponsored device/weapon, resulting casualties and the need for medical treatment could overwhelm the nation’s public health system.

Background/Aims: Radiation therapy is an important treatment for thoracic cancer; however, side effects accompanied with radiotherapy lead to limited tumor control and a decline in patient quality of life. Among these side effects, radiation-induced lung injury (RILI) is the most serious and common. Hence, an effective remedy for RILI is needed. Mesenchymal stromal cells (MSCs) are multipotent adult stem cells that have been demonstrated to be an effective treatment in some disease caused by tissue damage. However, unlike other injuries, RILI received limited therapeutic effects from implanted

Burn are diverse and complex injuries that not only have local effects but also serious systemic consequences through severe and prolonged inflammatory response. They are caused by heat, electricity, friction, chemicals, or radiation and are commonly divided into superficial, superficial partial-, deep partial- and full-thickness injuries. The severity of the burn depends mainly on the size and depth of the injury but also on location, age, and underlying systemic diseases. A prolonged and strong immune response makes major burns even worse by causing multiple systemic effects including damage

The frequency of thoracic injuries in the general structure of combat surgical trauma remains at the level of 7-12 % and unchanged from the time of the Second World War to the current armed conflicts. The overwhelming majority of them (up to 72 %) are shrapnel gunshot wounds. The formation of a gunshot wound occurs due to the action of a shock wave; a wounding projectile; energy of side impact and vortex wake.

PURPOSE: To determine whether changes in whole-lung pulmonary function test (PFT) values are related to the sum of predicted radiation therapy (RT)-induced changes in regional lung perfusion. PATIENTS AND METHODS: Between 1991 and 1998, 96 patients (61% with lung cancer) who were receiving incidental partial lung irradiation were studied prospectively. The patients were assessed with pre- and post-RT PFTs (forced expiratory volume in one second [FEV1] and diffusion capacity for carbon monoxide [DLCO]) for at least a 6-month follow-up period, and patients were excluded if it was determined that

Bisphenol A (BPA) is a low molecular weight chemical compound that has a deleterious effect on the endocrine system. It was used in plastics manufacturing with injurious effects on different body systems. Occupational exposure to low-level ionizing radiation (<1 Gy) is shown to attenuate an established inflammatory process and therefore enhance cell protection. Therefore, the objective of this study was to investigate the protective effect of boswellic acid (BA) accompanied by whole-body low-dose gamma radiation (γ-R) against BPA-induced lung toxicity in male albino rats.

We examined the effect of regional pulmonary blood flow (PBF) on lung water measurements made with a blood-borne label (15O-water) and positron emission tomography (PET) in five dogs. The total lung water (TLW) content of a lung region obtained at equilibrium after intravenous injection of 15O-water (TLW-water) was compared with calculations made from lung density measurements (TLW-density) also obtained with PET. These latter measurements are proportional to the tissue attenuation of radioactivity originating from an external source encircling the animal and are independent of PBF. Comparison

The burns are tissue damage caused under the influence of pathogenic amounts of heat, chemicals, electricity or radiation of different bodies.Etiological factors generally can be divided into four groups: thermal, chemical, electrical and radiation burns.Tissue damage is directly related to high temperature and length of exposure to harmful agents. The higher the temperature and longer works, the damage was more severe. Etiologic agents can cause minor injuries in the form of erythema of the skin, and severe destruction of body parts or the whole organism. System changes occur and are particul

Radiation therapy provides an appropriate radiation dose to tumors. The proportion of this dose varies according to the injured part and its location. Targeting the part affected by the tumor with an appropriate radiation dose requires high accuracy in measuring from the radiation source to the patient and the amount of dose. This treatment was applied using digital linear accelerators and computers to treat the tumor with radiation. In most cases, it is used chemotherapy, one of the standard cancer treatments. However, those doses affect the patient as it leads to loss of appetite, which nega

We have previously shown that injury induced by irradiation to murine marrow can be partially or completely reversed by exposure to human or murine mesenchymal stem cell (MSC)-derived extracellular vesicles (EVs). Investigation of the biodistribution of EVs in vivo is essential for understanding EV biology. In this study, we evaluated the DiD lipid dye labeled MSC-EV biodistribution in mice under different conditions, including different MSC-EV doses and injection schedules, time post MSC-EV injection, and doses of radiation. DiD-labeled MSC-EVs appeared highest in the liver and spleen; lower

Abstract We have previously demonstrated that murine bone marrow cells co-cultured with lung opposite a cell-impermeable membrane express high levels of lung cell-specific genes (Aliotta et al, Stem Cells, 2007;25(9):2245–56). Greater changes in gene expression were noted in marrow cells co-cultured with radiation-injured lung. A factor smaller than the pore size of the cell-impermeable membrane (0.4μm) is responsible for these changes as cell-free conditioned media (CM) had a similar effect on co-cultured marrow cells. Lung-derived microvesicles were found to enter marrow cells in culture and

Abstract Gelsolin is a highly conserved intracellular actin-binding protein with an extracellular isoform named plasma gelsolin (pGSN). Relatively high (250 mg /L) blood concentrations of pGSN decrease in response to trauma, major surgery, sepsis, burns, ionizing radiation, and hyperoxia. Depletion of pGSN to a critical (~20%) level precedes and predicts complications of primary injuries such as lung permeability changes, ARDS, assisted ventilation and death. Administration of recombinant pGSN ameliorates such complications and reduces mortality in animal models. A proposed mechanism for pGSN’

It is well established that exposure to high levels of oxygen (hyperoxia) injures and kills microvascular endothelial and alveolar type I epithelial cells. In contrast, significant death of airway and type II epithelial cells is not observed at mortality, suggesting that these cell types may express genes that protect against oxidative stress and damage. During a search for genes induced by hyperoxia, we previously reported that airway and alveolar type II epithelial cells uniquely express the growth arrest and DNA damage ( Gadd) 45a gene. Because Gadd45a has been implicated in protection agai
