Effects of Cardiac Glycosides
Using microelectrodes having an external diameter of less than 1 ,u, potential variations of single caidiac fibers were obtained from frog ventriculai' muscle in situ. The normal membrane potential consists of a rapid depolarization and slow reecovery, the latter occurring in three distinct phases. Digitalis glycosides alter profoundly the slopes of these various phases and dlastically shorten ...

and tricuspid regurgitation, indicative of increased right ventricular stroke volume. A pulmonary-to-systemic flow ratio of 2:1, due to an ostium secundum type-atrial septal defect, could be accurately diagnosed by Doppler echocardiography. Symptoms disappeared sponta-nously within a few minutes after hospital admission without therapy. Laboratory examination revealed elevated serum concentrati...
متن کاملThe Cardiac Glycosides
author offers no evidence to support his own contentions other than "laboratory studies show," "phylobiological investigations show," "my researches and those of my associates show." A really specific account of the therapeutic method to be used, or how the physiological method is to be applied, is found nowhere in the book, nor are any concrete case histories supplied. A much-needed glossary, ...
متن کاملSpray detection of phospholipids on thin-layer chromatograms.
A new spray reagent with copper, ammonium molybdate, and sulphuric acid for the detection of phospholipids on thin-layer chromatograms is described. The specificity and sensitivity of the spray reagent is also shown.
متن کاملCardiac glycosides and cardiomyopathy.
Digitalis-like steroids and related agents have been a mainstay in the treatment of congestive heart failure ever since the publication, in 1785, of Withering’s seminal monograph on foxglove. Heart failure refers to the clinical syndrome that results when the heart is unable to pump sufficient blood to keep up with the metabolic demands of the body. Congestive heart failure is characterized by ...
