A perfusion model of global cerebral ischemia was used for the immunohistochemical study of changes in the glutamate-nitric oxide (NO) system in the rat cerebellum and cerebellar nuclei during a 0-14 h reperfusion period after 30 min of oxygen and glucose deprivation, with and without administration of 1.5 mM N(omega)-nitro-L-arginine methyl ester (L-NAME).(More)
Adrenomedullin (AM) is a novel vasodilator peptide first purified from human pheochromocytoma by tracing its capacity to stimulate cAMP production in platelets. AM immunoreactivity is widely distributed in the central nervous system (CNS) and in the rat has been demonstrated by immunohistochemical techniques to be present in many neurons throughout the(More)

BACKGROUND Interaction with heparan sulfate proteoglycans is supposed to provide chemokines with the capacity to immobilize on cell surface and extracellular matrix for accomplishing both tissue homing and signaling of attracted cells. However, the consequences of the exclusive invalidation of such interaction on the roles played by endogenous chemokines in(More)
Neuronal and inducible nitric oxide synthase (nNOS and iNOS) and nitrotyrosine immunoreactivities were localized and semiquantitatively assessed in the cerebral cortex of aged rats by means of light microscopic immunocytochemistry and Western blotting, using a new series of specific polyclonal antibodies. In the aged rats the strongly nNOS-immunoreactive(More)
Adrenomedullin is a multifunctional amidated peptide that has been found in most nuclei of the CNS, where it plays a neuromodulatory role. An adrenomedullin binding protein has recently been found in plasma and characterized as complement factor H. This regulator of the complement system inhibits the progression of the complement cascade and modulates the(More)
Changes in the pattern of adrenomedullin expression in the rat cerebral cortex after ischemia-reperfusion were studied by light and electron microscopic immunohistochemistry using a specific antibody against human adrenomedullin (22-52). Animals were subjected to 30 min of oxygen and glucose deprivation in a perfusion model simulating global cerebral(More)
Changes in the distribution of immunoreactive cytochrome c and protein nitration were studied in the rat cerebral cortex after oxygen and glucose deprivation by bright field, confocal and electron microscopy. In control cerebral cortex, nitrotyrosine immunoreactivity indicating protein nitration was found mostly in the neuronal nuclear region, with only a(More)
