Myocardial Balance of Inorganic Phosphate and Enzymes in Man

Myocardial balance of inorganic phosphate and enzymes in man. Effects of tachycardia and ischemia.

The effects of atrial pacing on the cardiac balance of inorganic phosphate (Pi) were studied during control, atrial pacing, and recovery periods in 29 patients. Group A (n= 18) who had roentgenographically demonstrated coronary artery disease (CAD) developed angina during pacing, and showed mean myocardial lactate (L) production, abnormal left ventricular end-diastolic pressure (LVEDP) and ST s...

Urinary Excretion and Serum Concentration of Inorganic Phosphate in Man.

the tragedy of modern man in arthur millers world

what miller wants is a theatre of heightened consciousness. he speaks of two passions in a man, the passion to "feel" and the passion "know". he belives that we can have more of the latter. he says: drama is akin to the other inventions of man in that it ought to help us know more and not merely to spend our feelings. the writing of the crucible shows us that he is trying to give more heightene...

Effects of Alkalosis on Plasma Concentration and Urinary Excretion of Inorganic Phosphate in Man.

In 1924, Haldane, Wigglesworth, and Wood-row reported on the effect of reaction changes on human inorganic metabolism (1). They found that respiratory alkalosis caused a sharp fall and respiratory acidosis a sharp rise in serum phosphorus concentration. They also examined metabolic changes induced by oral ingestion of Na-HCO3 or NH4Cl for several days, but respiratory compensation would have mi...
