to investigate the interrelation among endogenous catecholamines , prolactin and prostaglandin f2 alpha , we measured the plasma levels of dihydroxyphenylalanine ( dopa ) , norepinephrine ( ne ) , catecholamine metabolites ( 3,4-dihydroxyphenylacetic acid [ dopac ] , 3,4-dihydroxyphenylethyleneglycol [ dopeg ] , cyclic 3',5'-adenosine-monophosphate ( c-amp ) , prostaglandin f2 alpha ( pgf2 alpha ) and prolactin ( prl ) in 119 patients , before , during and after a normal labor and delivery , and in the early puerperium .
