A Bobik et al.
Journal of cardiovascular pharmacology, 6(5), 795-801 (1984-09-01)
We examined the effects of prolonged exposure of cardiac cells in primary culture to the partial beta-adrenoceptor agonist prenalterol and inhibitors of phosphodiesterase on their subsequent ability to increase intracellular cyclic AMP during a 5-min exposure to 50 microM isoprenaline
C B Archer et al.
The British journal of dermatology, 109(5), 559-564 (1983-11-01)
Peripheral blood lymphocyte cyclic AMP responses to isoprenaline, prostaglandin E2 and histamine were examined in patients with atopic eczema, in the presence and absence of a potent phosphodiesterase inhibitor (PDEI). Basal cyclic AMP levels were not significantly different in atopic
T Hermsdorf et al.
Cellular signalling, 10(9), 629-635 (1998-10-30)
Primary cultures of rat hepatocytes were used to study the combined effects of insulin and dexamethasone on cyclic AMP phosphodiesterase 3 (PDE 3) and glycogen metabolism. PDE activity was measured in extracts obtained by hypotonic shock treatment of the particulate

Naunyn-Schmiedeberg's archives of pharmacology, 343(2), 161-165 (1991-02-01)
The aim of the present investigation was to examine whether or not presynaptic facilitatory beta-adrenoceptors are detectable on the postganglionic nerves in the rabbit isolated ear artery. Strips of rabbit central ear artery were incubated with 3H-noradrenaline (10(-7) mol/l; 30

The significance of a characteristic symptomatology (hypothermia, hypoactivity, forepaw shaking, grooming, head twitches) as a potential in vivo correlate of enhanced availability of brain adenosine cyclic 3',5'-monophosphate (cAMP) was examined in rats following systemic administration of various doses of dibutyryladenosine
