Before the preganglionic regulation of the adrenal medulla is established, hypoxia acts directly on the chromaffin cells to evoke the secretion of catecholamines. This direct action of hypoxia is suppressed by the gradual development of the preganglionic innervation and we

Recent studies suggest that delta-opioid receptors play a role in the development of opioid tolerance and led us to hypothesize that highly selective mu-opioid agonists may produce less tolerance. H-2',6'-dimethyltyrosine-D-Arg-Phe-Lys-NH(2) ([Dmt(1)]DALDA) has extraordinary selectivity for mu-receptors (K(i)(delta)/K(i)(mu) > 14,000). Daily

Previously, we reported that H-2',6'-dimethyltyrosine [Dmt(1)]-d-Arg-Phe-Lys-NH(2) (DALDA), an analogue of the naturally occurring opioid peptide dermorphin, is a highly potent and selective mu receptor agonist with low cross-tolerance to morphine. In the present study, we investigated the effect of treating

The synthetic peptide [Dmt(1)]DALDA (Dmt-D-Arg-Phe-Lys-NH(2); Dmt = 2',6'-dimethyltyrosine; 'super-DALDA') is a mu opioid-receptor agonist. On-line liquid chromatography/quadrupole time-of-flight mass spectrometry and the corresponding stable isotope-incorporated synthetic peptide internal standard were used to quantify [Dmt(1)]DALDA that had been extracted from ovine

The clinical effectiveness of morphine is limited by several side effects, including the development of tolerance and dependence. Most of these side effects are believed to be mediated by central opioid receptors; therefore, hydrophilic opioids, which don't cross the blood-brain
