The influences of trauma and TPN on pancreatic islet §hormone secretion in relation to islet expression of §iNOS synthase was investigated.§§Acute pancreatitis resulted in an impaired glucose-§stimulated insulin secretion (GSIS), which was found §to be parallelled by a marked expression of iNOS and §an exaggerated NO production in the pancreatic §islets. §A characteristic feature of long term TPN-treatment §is hyperlipidemia and euglycaemia. TPN treatment §impairs GSIS at least in part through a reduced §cyclic AMP production in parallell with an exclusive §expression of iNOS, which was reflected in an §increased NO production accompanied by enhanced §cyclic GMP formation by islets. §Agents stimulating cyclic AMP/PKA i.e. PACAP27 and §PACAP38 were capable of not only inhibiting neuronal §NOS (ncNOS) but also counteracting the expression of §iNOS induced by intralipid infusion. The suppressed §NO production in the presence of PACAPs was §reflected in a suppressed cyclic GMP and a marked §increase in cyclic AMP production by pancreatic §islets. §Finally, effects of ghrelin on islet hormone §secretion and NOS isoenzymes activities were also §studied.
