background: with the introduction of computed tomography in diagnostic radiology a new and fundamentally different imaging modality has become available. meanwhile, it is clear that the absorbed doses by the patients during ct were relatively high in comparison with those of other diagnostic radiology techniques. the aim of this survey was to determine the average absorbed dose in yazd province...

background: the rejected films in radiography may be responsible for an unnecessary increase in the radiation dose to the population. the effective dose to population is a very important factor in estimation of stochastic risk in radiology. the main goal of this study was to determine the effective dose to members of the public due to rejected films in diagnostic radiology departments in the no...

background: the main aim of the present study was to evaluate the ameliorative effect of curcumin on aflatoxin-induced changes in caput and cauda epididymis of mice. materials and methods: aflatoxin was obtained by growing aspergillus parasiticus in sucrose - magnesium sulphate - potassium nitrate - yeast extract (smky) liquid medium. pure curcumin (97% purity) was purchased from hi-media labor...

Combined extracts of Amaranthus spinosus roots and Dolichos biflorus seeds at two different doses were administered to adult male rats to assess the structural and functional activity of epididymis. Biochemical studies were made throughout the experiment. Sperm motility was decreased markedly in the cauda epididymal fluid and the sperm counts were reduced in both caput and caudal segments. Epid...

Direct communication between neighboring cells through connexin (Cx)-based gap junction is a crucial biolo-gical manner to regulate functions of a tissue consisting of multi-cell types. The present research evaluated expressional changes of Cx isoforms in the caput epididymis of adult rat exposed to estradiol benzoate (EB) or flutamide (Flu) at the early postnatal age. A single subcutaneous adm...

Nowadays, the radiological risk from simple X-ray procedures is well known. The purpose of this work has been to estimate the population risk from digital angiographic and interventional procedures and to compare it with the one from simple procedures in the same population. The population risk has been estimated according to the following quantities: genetically significant dose, somatic signi...

Background: Radiation dose knowledge through Xray examinations and their distribution in Iran provides useful guidance on patient dose reduction. The results of the entrance skin dose (ESDs) of five common radiographies in all radiology centers in Yazd province were reported in our previous study (2003). In the present study we have evaluated the collective effective dose of convention...
