The tissue levels of the glycolytic intermediates and adenine nucleotides were measured in
perfused rat hearts supplied with 20 mm glucose during the transition from aerobiosis to …

Earlier studies with the perfused rat heart have shown that the rate of glycolysis was
inhibited by the addition of fatt) y acids or ketone bodies to the perfusion medium (l-4). The …

1. In the isolated perfused rat heart, the contractile activity and the oxygen uptake were
varied by altering the aortic perfusion pressure, or by the atrial perfusion technique ('working …

1. The work of the perfused rat heart was acutely increased by raising the aortic pressure in
the Langendorff preparation from 50 to 120mmHg; within 1 min in perfusions with media …

Experiments were done in dogs with various durations of myocardial anoxia in the following
conditions:(1) so-called ischemic cardiac arrest in normo-or hypothermia;(2) anoxic …

The isolated perfused working rat heart preparation has been used to study the effects of
respiratory acidosis on myocardial metabolism and contractilly. Hearts were perfused with 5 …

A possible rate-limiting role of phosphofructokinase in muscle glycolysis was first suggested
by CogI (1942), when he interpreted observations, as showing administration of epinephrine …

The aim of this work was to study whether changes in fructose 2, 6-bisphosphate
