the degradation of trace amounts of synthetic [ ( 3 ) h ] enkephalins in the perfusing medium during stimulated release seems to reflect the accelerated degradation of enkephalin released from the tissue : 63 % of the met-enkephalin and 23 % of the leu-enkephalin were degraded in a medium containing bacitracin ( 30 mug/ml ) .
