OBJECTIVE To determine the possible association between cadmium (Cd) exposure and alterations in plasma lipid and lipoprotein levels and total antioxidant status (TAS) in rats. MATERIALS AND METHOD Twenty male albino rats assigned to 2 groups of 10 rats each (test and control) were used for the study. Each test animal model was given 1.0 mg CdCl(2)/kg body weight, administered intraperitoneal...

OBJECTIVES To determine if slight variations in exposure will affect diagnostic image quality and absorbed radiation doses for digital and analogue panoramic radiography. METHODS Thermoluminescent dosimeters were placed in the thyroid gland, eyes, submandibular glands, parotid glands and skin of two human cadaver heads. Three different exposure settings were used: 70 kV, 120 mAs; 77 kV, 75 mA...

Purpose: The purpose of this study was to preliminarily estimate patient-specific organ doses in chest CT examinations for Chinese adults, and investigate the effect patient size on doses. Methods: By considering body-size body-build effects taking mid-chest water equivalent diameter (WED) as a indicator, scan images 18 adults were acquired multi-detector generate regional voxel models. For eac...

Introduction: The aim of this study is to investigate the effect of partially used high photon energies on dosimetric parameters and integral doses of nasopharynx IMRT plans.   Materials and Methods: Two 7 coplanar IMRT plan were created for eleven patients (6 MV only IMRT plan in both phase1 and phase2 and 6 MV phase1-mixed energies (6 MV and 15 MV) phase2...

Background and Purpose: Use of curcumin, as a promising antifungal agent, is considered an alternative treatment for fungal infections; however, the low solubility of this agent limits its efficacy. Accordingly, in this study, we aimed to evaluate the in vitro and in vivo antifungal activities of dendrosomal nanocurcumin with improved solubility and bioavailability. Materials & Methods: The...

Background: Computed tomography angiography (CTA) scan is a suitable imaging technique to evaluate the blood vessels. However, one major disadvantage is the potential risk of cancer related to ionizing radiation exposure during the procedures. The aim of this investigation was to estimate the risk of exposure induced cancer death (REID) values for some common computed tomography angiography (CT...

In a study of the clinicopathologic syndrome of toxicity to phenacetin at the range of the acute, oral LD50j Boyd in 1959 (1) used adult female rats and reported the LD50±SE to be 1.65±0.35 g/kg body weight. In 1968, Boyd and Hottenroth (2) studied the toxicity of phenacetin at the range of the oral LD50 (100 days) and reported the acute oral LD50 ±SE in young male albino rats to be 4.14±0.71 g...

The purpose of this study was to compare estimation of radiation absorbed doses to patients following bone scans with technetium-99m-labeled methylene diphosphonate (MDP) with the estimates given in MIRDose software. In this study, each patient was injected 25 mCi of (99m)Tc-MDP. Whole-body images from thirty patients were acquired by gamma camera at 10, 60, 90, 180 minutes after (99m)Tc-MDP in...
