Kay and coworkers (1) have shown an increased excretion of taurine by rats after total body x-irradiation. It has been demonstrated previously (24) that methionine, cysteine, and glutathione are precursors of taurine. In view of the well established effect of irradiation on sulfhydryl groups described by Barron and his associates (5-7), it seems probable that the increase in the excretion of ta...

results histopathologically, a decrease (statistically not significant) in the thickening of alveolar or bronchial wall, formation of fibrous bands, and superimposed collagen were noted in the animals in group b as compared to the animals in group a. conclusion in this experimental study, administration of gla one hour before thoracic irradiation may be a protective agent against radiation-indu...

The effects of Ga-Al-As diode laser (830 nm, 16.2 mW) irradiation on the distal portion of the processes of cultured murine dorsal root ganglion (DRG) neurons associated with C-fibers were studied by patch-clamp whole-cell recording of membrane potentials at the cell body. The chemical as well as laser light stimulations were limited to the processes of the neuron isolated from the cell body wi...

Biological dosimetry based on the analysis of cytogenetic damage in peripheral lymphocytes of the exposed person is a well established technique [10]. The absorbed dose is estimated by comparing the scored number of aberrations with a calibration curve, obtained by in vitro irradiation of whole blood collected from control persons. Several authors have validated this procedure by testing experi...

Several studies have shown that total body irradiation decreases the angiogenic response to corneal cauterization. This inhibition could be due to alterations in angiogenic stimuli within injured corneas and/or to a decreased ability of irradiated animals to respond to such stimuli. To determine whether total body irradiation specifically affects angiogenic stimuli within injured corneal tissue...

The aim of this study is to evaluate the incidence of interstitial pneumonitis following fractionated total body irradiation conditioning for bone marrow transplantation with varying lung doses due to shielding technique and different dose-rates. Between 1987 and 2001, a total number of 105 patients have received total body irradiation conditioning for bone marrow transplantation for hematologi...

the aim of present study was to investigate the potential antioxidant and lung protective activities of sambucus ebulus (se) against toxicity induced by gamma irradiation. hydro alcoholic extract of se (20, 50 and 100 mg/kg ) was studied for its lung protective activity. . phenol and flavonoid contents of se were determined. male c57 mice were divided into 10 groups with five mice per group. on...

OBJECTIVE This study aimed at comparing the effect of linear polarized near-infrared light irradiation (PL irradiation) and bicycle exercise with 50%HRreserve on the flexibility of the shoulder joint. DESIGN Placebo-controlled trial. SETTING Twenty-four healthy young adults (10 males: mean+/-SD, age 20.9+/-3.1 y, height 171.0+/-3.9 cm, body mass 63.4+/-3.5 kg and 14 females: age 21.2+/-1.7 ...

The influence of a host defense protein, lactoferrin (LF), contained in exocrine secretions such as milk, on radiation disorder was investigated. A total of 25 C3H/He mice in each of two groups were maintained with 0.1% LF-added and LF-free diets, respectively, for one month. The mice were then treated with single whole-body X-ray irradiation at a sublethal dose (6.8 Gy), and the survival rate ...

Ionizing radiation causes its biological effects mainly through oxidative damage induced by reactive oxygen species. Previous studies showed that ozone oxidative preconditioning attenuated pathophysiological events mediated by reactive oxygen species. As inhalation of ozone induces lung injury, the aim of this study was to examine whether ozone oxidative preconditioning potentiates or attenuate...
