We measured with radioimmunoassay the {beta}-endorphin-like and {alpha}-MSH-like immunoreactivities in milk and plasma of 8 lactating women. Mean {beta}-endorphin concentrations ({plus minus} SD) were 16.6 {plus minus} 6.7 fmol/ml in milk and 9.9 {plus minus} 4.1 fmol/ml in plasma. {alpha}-MSH concentrations were 39.4 {plus minus} 15.5 pg/ml in milk and 18.2 {plus minus} 8.4 pg/ml in plasma. The concentrations of both peptides in milk were significantly higher than in plasma. No significant correlation between milk and plasma concentrations of these peptides was found.
