3,4-dichlorophenylacetamidine slightly reduced epinephrine levels in the adrenal glands of exercised rats , but the effect may have been due to release rather than inhibition of synthesis , since heart norepinephrine levels were also reduced significantly by that agent ( which is from a chemical series known to release catecholamines ) .
