Newer methods for detecting subclinical thrombosis are discussed. Uses of radionuclides for thrombus localization are reviewed. Laboratory tests suitable for nonspecialized laboratories are highlighted. The serial use of functional antithrombin III and ethanol gelation assays are recommended to follow the effect of anticoagulant therapy. The use of heparin therapy in low dosage is discussed.

Introduction: The present study was conducted to measure the specific activities of 226Ra,232Th and 40K, in some samples of nuts collected from the local markets in Iraq. In addition, this study sought to calculate the annual effective dose of gamma ray to children and adults. Material and Methods: The quantification of radionuclides was accomplished by gamma spectrometry NaI (Tl) detector. Res...

BACKGROUND Patients undergoing radiation therapy for oral squamous cell carcinoma (OSCC) have an increased risk of developing oral candidiasis. Radiation-induced hyposalivation is thought to be a major predisposing factor for it. Radiation therapy for 2-3 weeks leads to increase in the number of candidal species in the oral cavity, eventually leading to oral candidiasis. OBJECTIVE To evaluate...

background and objective: the most common intravascular brachytherapy sources include 32p, 188re, 106rh and 90sr/90y. in this research, skin absorbed dose for different covering materials in dealing with these sources were evaluated and the best covering material for skin protection and reduction of absorbed dose by radiation staff was recognized and recommended. method: four materials includin...

PET uses specific molecules labelled with positron-emitting radionuclides to provide valuable biochemical and physiological information. However, the administration of radiotracers to patients exposes them to low-dose ionizing radiation, which is a concern in the paediatric population since children are at a higher cancer risk from radiation exposure than adults. Therefore, radiation dosimety c...

introduction artificial and natural radionuclides are found in diverse environmental compartments, such as water, soil, rocks, vegetables, animals, and human body tissues. as such, humans and environments are at constant exposure of these radiation types. in this research investigated specific activities of radionuclide and dose assessment of some species of mushrooms. materials and methods in ...

background: the equivalent dose in the human body due to the natural gamma-emitting radionucides (238u, 232th and 40k) in the surface soil surrounding the consolidated tin mine site in bukuru-jos, nigeria has been determined in this study. materials and methods: measurements of the soil natural radioactivity were made using a multi-channel pulseheight analyzer (canberra series 10 plus) coupled ...

Radionuclides in the environment are one of the major concerns to human health and ecotoxicology. The explosion at the Chernobyl nuclear power plant renewed interest in the role played by fungi in mediating radionuclide movement in ecosystems. As a result of these studies, our knowledge of the importance of fungi, especially in their mycorrhizal habit, in long-term accumulation of radionuclides...

Introduction: This study was conducted to measure the gamma emitters (e.g., uranium-238 [238U], thorium-232 [232Th], and potassium-40[40K]) and alpha emitters (e.g., radon-222 [222Rn] and radium), and also to evaluate the radiation hazard indices of radionuclides in parenteral nutrition samples utilized in the hospitals of Iraq. Material and Methods: The measurements were accomplished using ga...
