title: Asphyxia-induced release of alpha-melanocyte-stimulating hormone in newborn pigs.
abstract: Asphyxia and reperfusion induced changes in the plasma and cerebrospinal fluid (CSF) concentrations of alpha-melanocyte-stimulating hormone (alpha-MSH) were studied in newborn pigs using a specific radioimmunoassay technique. Cardiovascular and metabolic failure induced by neonatal asphyxia resulted in a 3-fold, significant (P < 0.05) increase in plasma alpha-MSH levels, whereas the hormone concentration in CSF was significantly (P < 0.05) reduced by 50% during postasphyxial reperfusion. Our data indicate an asphyxia-induced release of alpha-MSH, and suggest a discordant regulation of plasma and CSF concentrations in newborn pigs.
