Two previously healthy women developed nausea, vomiting, headache and dizziness for several days, a massive hair loss about 2 weeks later and a discoloration of the fingernails. Detailed diagnostic procedures did not reveal any pathological results. Therapeutic measures did not show any effect. Thallium and arsenic were within normal range in plasma. Delayed quantitative determination of seleni...

BACKGROUND In patients with coronary artery disease, stress-redistribution-reinjection thallium scintigraphy provides important information regarding myocardial ischemia and viability. Although both reversible and mild-to-moderate irreversible thallium defects retain metabolically active, viable myocardium, we hypothesized that stress-induced reversible thallium defects may better differentiate...

thallium 201 whole body scintigraphy was performed in a 30 year old patient with diffuse osseous metastatic disease secondary to glioblastoma multiforme. multiple sites of thallium uptake correlated with the findings on serial bone scans and radiographs. bone biopsy of a lower lumbar vertebra confirmed that the metastases were of glial origin.

Rodenticide or insecticide formulations in the form of syrups, jelly or pastes. Often applied to foods such as cookies, cakes, peanut butter or grain. Commercial preparations, such as ant traps, ant baits and rat poisons generally contain 0.5 1.0% thallium. In 1963, the federal government adopted legislation prohibiting the sale of thallium containing pesticides to the general public. In commer...

Thallium is a toxic heavy metal often involved in criminal poisonings and occasionally in accidental poisoning. Here, we report a case of acute, nonintentional thallium poisoning due to thallium-contaminated alternative medicine for its rarity and to create awareness about the combination of rapid, diffuse alopecia with neurologic and gastrointestinal symptoms among practitioners, professionals...

The kinetics of carbamoylcholine-mediated cation transport across the membrane of vesicles containing acetylcholine receptor have been measured on the physiologically relevant time scale of a few milliseconds. The stopped-flow spectroscopic approach utilizes thallium(I) as the cation transported into sealed vesicles containing a water-soluble fluorophore. Upon entry of thallium(I), fluorescence...

although thallium-201 exercise scintigraphy has been established for the detection of myocardial ischemia and viability, little is known regarding the myocardial thallium-201 kinetics during angioplasty. herein, we report a 77-year old man with angina pectoris, in whom serial myocardial imaging after a single dose of thallium-201 was helpful in identifying not only the culprit lesion and myocar...

The aim of this study was to assess the incidence of myocardial infarction among persistent perfusion defects in dipyridamole-stress thallium scintigraphy by inspecting autopsied hearts and to evaluate whether the regional thallium activity of a scintigraphic defect can predict the presence of infarction. Autopsied hearts were compared with dipyridamole myocardial scintigrams undertaken during ...

Most of the thallium uptake by canine iliac arteries (70%) was inhibited by ouabain. The component sensitive to ouabain was significantly increased by incubating tissues in K+-free solution and reduced by low temperatures, metabolic inhibitors, and loading with lithium. The apparent Km for thallium for the ouabain-sensitive uptake was 0.47 +/- 0.046 mM. External K+ inhibited thallium uptake and...
