Several studies have been performed in patients with a variety of myocardial diseases that have identified a prolongation of tau. However, it is not clear whether prolongation of tau represents abnormal myocardial physiology or the effect of excessive load associated with a particular disease process. Accordingly, we evaluate the effect on tau of an(More)
Aneurysms of the left main coronary artery are exceedingly rare clinical entities, encountered incidentally in approximately 0.1% of patients who undergo routine angiography. Thrombosis within the aneurysm can lead to distal embolization and myocardial infarction. These lesions can extend into adjacent coronary branches and can occur in the presence or(More)
There is little information concerning the prevalence and clinical correlates of increased pulmonary thallium-201 uptake during dipyridamole thallium-201 stress imaging. Accordingly, the clinical characteristics and quantitative thallium-201 findings were correlated with quantitative lung/heart thallium-201 ratio in 87 patients undergoing dipyridamole(More)
Data comparing myocardial thallium-201 imaging after exercise and intravenous dipyridamole infusion in the same patients are scarce. Accordingly, this study is a segment-by-segment quantitative analysis of regional uptake and washout of thallium-201 after dipyridamole (0.56 mg/kg) and symptom-limited exercise testing in 21 patients (ages 58 +/- 9.2 years)(More)
The use of Lithium Carbonate (Li2CO3) therapy in Gilles de la Tourette syndrome is reported in one patient. The patient, a 22-year-old male, was treated with a daily dose of 900 mg of Li2CO3 to attain therapeutic blood serum lithium concentration between 0.76 and 0.87 mEq/L. Renal function tests, urine analysis and thyroid function tests were monitored in(More)
Of 36 adult female rats studied 19 were radiothyroidectomized; 3 weeks later all rats were bred. Radiothyroidectomized rats were divided into Groups I-III. Group I was untreated. Maternal weight gain was not noted until day 9 and was steady thereafter. Group III rats were treated with triiodothyronine up to the first day of pregnancy, but were hypothyroid(More)
A 10% ethanol (ET) solution was the only drinking fluid available for 60 days prior to and during pregnancy which was continued until neonatal rats were weaned. The 18 day old fetus and its liver weight of ET drinking rats were significantly decreased from water drinking controls. Liver and body weights of 14 and 21 day old neonates of both sexes were(More)
