Angiocardiography and cineangiocardiography have been employed with increasing frequency for the diagnosis of cardiovascular diseases. These commonplace technics of cardiovascular radiology depend upon the rapid injection of hypertonic contrast media into the heart or central circulation. In order to study the effects of concentrated radiopaque materials(Conray®, 1382 mOsm/L, 1-2 ml/ kg) on hemodynamic consequences, the changes of serum osmolality, sodium, potassium, chloride, digoxin-like substance and...

To digoxin-like substance, the authers tried to confirm the presence of this substance in cord blood, sera from premature and full-term infants, third trimester pregnant women not receiving digoxin, and placental extracts, and to investigate the origin and potential physiologic role of DLS, endogenous Na+, K+-ATPase inhibitor in relation to renin activity. The results were as follows; 1) Cord sera DLS...
