title: Glycogenolysis and control of anaphylactic histamine release by cyclic adenosine monophosphate-related agents. II. Modification of histamine release by glycogenolytic metabolites.
abstract: D-glucose-6-phosphate (less than or equal to 5 x 10(-3) M), pyruvate, lactate (less than or equal to 1 X 10(-2) M), and dibutyryl cyclic AMP (less than 5 X 10(-3) M) were capable of inhibiting anapylactic histamine release in vitro from chopped guinea pig lung. In lower concentrations, pyruvic acid and lactate, as well as dibutyryl cyclic AMP, enhanced the release. Significant synergism was observed betweenpyruvate (5 X 10(-3) M) and isoproterenol (1 X 10(-8) M) in the inhibition of histamine release. The inhibitory actions of isoproterenol, glucose-6-phosphate, and pyruvate were influenced by calcium ion concentration. However, beta blockade, which diminished the isoproterenol effect, was without efect on pyruvate (1 X 10(-2) M) to the release system. Glucose-6-phosphate and isoproterenol did not have this effect. The results, together with a prevouus study, suggest that glycogenolysis may possess a role in the anaphylactic istamine release in vitro from sensitized lung fragments...
