purpose: to design and manufacture iodine 125 radioactive plaques which can be used in patients with ocular melanoma, and to evaluate the efficacy of plaques in an animal model. methods: this prospective basic study was performed in collaboration with farabi hospital and tehran atomic energy agency. the iodide 125 plaques were designed and manufactured based on the collaborative ocular melanoma...

The disorders of the thyroid gland are on rise. Radioactive iodine (RAI- I-131) is now used for treatment hyperthyroidism and carcinoma. This helps in destruction follicular cells radiation help annulling cancer cells. RAI has many adverse effects; short-term effects include – gastrointestinal, salivary dysfunction, thyroiditis, long-term - secondary carcinomas. facilities giving radioactive th...

Phytoremediation of radioactive waste is a process that uses plants to remove, transfer, or immobilize radionuclides from the contaminated soil, sediment, sludge, or water, and it is a useful method for treating large-scale low-level radionuclide contamination. However, there have not been established criteria which can be utilized to screen out suitable plant species that are capable of remedi...

Measurement of regional myocardial blood flow (RMBF) is crucial in experimental studies of myocardial ischemia and reperfusion in dogs. The standard measurement technique uses radioactive microspheres; however, not all institutions are able to dispose of radioactive waste and therefore cannot make use of this method. We tested a new, nonradioactive microsphere, labeled with colors instead of nu...

the treatment of thyroid cancer using an unsealed source of radioactive materials is usually associated with a large amount of 131i. a major problem for hospital admission of these patients is the waste disposal which requires protection of the public. 152 patients with thyroid cancer admitted to the nuclear medicine department of said ai- shohada hospital for ui i treatment were studied. 1311 ...

Halothane is thought to cause hepatitis after multiple exposures in certain susceptible patients. Patients undergoing repeated anaesthetics for insertion of radioactive implants for gynaecological neoplasia appear to be particularly at risk. We are reporting three cases in which hepatitis has followed multiple halothane anaesthetics, and discuss them with reference to our present knowledge of t...

RADIOACTIVE Iodine (131I) is frequently recommended as the treatment of choice for thyrotoxicosis in patients over 45 years old without sufficient appreciation of the difficulties in management that occasionally occur. The increasing frequency of post-radiation myxoedema is now widely recognised (Green and Wilson, 1964) but less emphasis has been paid to the situation in some subjects in whom t...

PURPOSE Patients diagnosed with pancreatic cancer typically have a poor prognosis. The aims of these studies were to design radioactive stents and to evaluate the feasibility and safety of the stents in animals. EXPERIMENTAL DESIGN To combine the effects of stents and brachytherapy, plastic stents with inserted iodine-125 seeds were designed and tested in 18 normal pigs. The pigs were divided...

It is now thirteen years since Hertz and Roberts (1942) introduced radioactive iodine in the treatment of thyrotoxicosis, and in the succeeding years it has increasingly established itself in the therapy of this condition and has been widely used in the United States of America. We have previously recorded our experience in this country in a small series of cases (Blomfield et al., 1951, 1953; ...

Radon and progeny ((218)Po, (214)Pb, (214)Bi and (214)Po) in thermal spas are well known radioactive pollutants identified for additional radiation burden of patients due to the activity concentration peaks which appear during bath treatment or due to drinking of waters of high radon content. This burden affects additionally the working personnel of the spas. The present paper has focused on th...
