Various by nature extreme factors (hypoxic hypoxia, CO intoxication, chemical influence, noise and hypokinesia) caused similar changes in cAMP levels in different organs of albino rats (liver, the great cerebral hemispheres, heart). There was a significant increase in cAMP concentrations during the first stages of the influence and a progressive fall when(More)
A number of investigated cAMP derivatives are shown to inhibit the cAMP-phosphodiesterase in brain tissues of white rats in vitro. The 8-substituted aminoethylamino-derivatives proved to be effective inhibitors of the enzyme. Among them the most pronounced inhibition displayed the 8-(beta-aminoethylamino)-cAMP. In an in vitro experiment on the model of(More)
The paper is concerned with the data indicating close interaction between xanthinoxidase (Xase) and phosphodiesterase (PDE). PDE activity can be modified by affecting the activity of Xase. This effect is mediated by changes in the concentrations of endogenous xanthines. The action of PDE inhibitors, methylxanthines, is discussed from the point of view of(More)
