title: Cyclic AMP phosphodiesterase activity in Fasciola hepatica (L.) homogenates.
abstract: The authors have studied the bahaviour of cyclic 3',5'-AMP phosphodiesterase in the 2,000 g supernatant of the Fascilola hepatica homogenate, under basal conditions and after addition of various substances. Dopamine remarkably inhibits the enzyme activity, imidazole causes a strong activation, while serotonin, theophylline, PGE1 and PGF2alpha appear to be ineffective.
