RATIONALE AND OBJECTIVES: Our aim is to document current imaging practices for diagnosing acute pulmonary embolism (PE) among physicians practicing in the United States and explore factors associated with these practices. MATERIALS AND METHODS: Between September 2004 and February 2005, we surveyed by mail 855 physicians selected at random from membership lists of three professional organizations. Physicians reported their imaging practices and experiences in managing patients with suspected acute PE during the preceding 12 months...

It has been suggested that plasma sulfoconjugated dopamine (DA) may serve as a source or reservoir for free DA in plasma. Moreover, it has also been reported that the plasma levels of conjugated DA may be used as an index predicting heart failure in patients with heart disease. Therefore, in the present study, we have measured the plasma levels of free and sulfoconjugated DA in patients with congenital heart disease who underwent total corrective operations. The patients were divided into two groups with (6 patients with tetralogy of Fallot, TOF) or without (5 patients with ventricular septal defect without pulmonary hypertension, VSD) cyanosis (mean age of 2...

Two thrombolytic agents are mainly used in patients: streptokinase (SK) and urokinase (UK). UK from human origin is an endopeptidase which is able to convert plasminogen into plasmin. UK is only secreted by the kidney and is only found in urine which is presently the only source of extraction. Studies in man have shown that UK produces a highly reproducible state of enhanced plasma thrombolytic activity with a high fibrinolysis/fibrnogenolysis ratio and a lack of toxicity and antigenicity. The half life in Animal is short as well as the duration of fibrinolytic activity in Man...
