the hypothesis that catecholamines may be released by mammary gland stimulation during lactation was tested by measuring , with an hplc electrochemical method , plasma epinephrine ( e ) and norepinephrine ( ne ) concentrations during suckling in conscious rats and during electrical stimulation ( pulses : 1 msec duration , 10/sec at 5-30 v ) of the central end of a cut abdominal mammary nerve in urethane-anesthetized rats .
