Studies on Chemical Protection against Radiation. I. the Protective Effect of Orotic Acid against X-radiation Death in Mice.
An experiment was carried out to determine the protective effect of orotic acid (uracil-4-carboxylic acid) against X-rays. Orotic acid in dose of 0.05, 0.1, 1.0, 1.7 and 10 mg per mouse was given intra peritoneally to mice before or after a single dose whole-body X irradiation of 700 r or 550 r, after which the 30-day survival rate was observed. As a result it was concluded that it would be dif...
متن کاملProtective effects of silybin and analogues against X-ray radiation-induced damage.
Silybin (SLB) and similar analogues, namely, hesperetin (HESP), naringenin (NAN) and naringin (NAR), are believed to be active constituents of natural flavonoids that have been reported as chemopreventive agents for certain cancers. Moreover, SLB and analogues have been determined to fast repair DNA bases from oxidative damage by pulse radiolysis techniques. The present study was designed to ev...

متن کاملEffective Dose of Radiation in Diagnostic and Interventional Cardiac Angiography among Pediatrics and Adolescents in Hospitals of Shiraz University of Medical Sciences versus Other Radiology Devices
Background: Cardiac catheterization and angiography are diagnostic and therapeutic imaging modalities that produce the highest X-ray radiation, which might impose lifelong risks to patients. This study aimed to evaluate radiation burden among children and adolescents with congenital heart diseases, who underwent cardiac catheterization and angiography. Then the results were compared with other ...
متن کاملRadiation attenuation properties of shields containing micro and Nano WO3 in diagnostic X-ray energy range
Background: It has recently been shown that the particle size of materials used for radiation shielding can affect the magnitude of radiation attenuation. Over the past years, application of nano-structured materials in radiation shielding has attracted attention world-wide. The purpose of this study was to investigate the shielding properties of the lead-free shields containing micro and nano-...
