Effect of chronic [Dmt1]DALDA treatment on antinoceptive response to DAMGO (i.t.). Mice were treated for 7 days with [Dmt1]DALDA by twice daily injection (s.c.) with 2.5 μmol kg−1 of the peptide, or with saline (0.1 ml (10 g−1)). The AD50 values of DAMGO (i.t.) were determined by tail flick, using at least 10 animals per group.
