Could it be that there's something else using the krb5 ports?
Release of vasoactive neuropeptides in the isolated bovine aorta: effect of adrenergic agents and hypoxia.
We studied the release of vasoactive neuropeptides from the bovine aorta. Isometric force recordings were used to measure the contractile responses of the aorta to alpha- and beta-adrenoceptor agonists and potassium ionophore A23187. After incubation in a nutrient medium containing propranolol (10 microM) to suppress the release of endogenous catecholamines, noradrenaline, adrenaline and acetylcholine induced concentration-dependent contractions. In addition, high concentrations of potassium ionophore induced the contraction of the aorta. In the presence of dibutyryl cyclic adenosine monophosphate (0.1 mM), noradrenaline, adrenaline and acetylcholine evoked contractions that were less than 10% of those observed in the absence of this compound. However, the contractions induced by high concentrations of potassium ionophore were comparable to those seen in the absence of cyclic adenosine monophosphate. We detected the release of neuropeptides from the aorta that have previously been shown to be present in sympathetic ganglia. We studied the release of neuropeptide Y (NPY), substance P (SP), galanin (GAL) and calcitonin gene-related peptide (CGRP). Incubation of the aorta in nutrient medium, which contains phentolamine (10 microM) to block alpha-adrenoceptors, induced the release of NPY, GAL and CGRP, but not SP. The release of NPY and GAL was significantly reduced by treatment with dibutyryl cyclic adenosine monophosphate. The release of CGRP was increased by incubation with dibutyryl cyclic adenosine monophosphate. The release of SP was not influenced by incubation in nutrient medium. In contrast to the release of NPY, GAL and CGRP, the release of SP was increased by treatment with
