Arginine vasopressin (AVP), a nonapeptide hormone of posterior pituitary, reaches the central nervous system from systemic blood circulation with a difficulty because of the blood-brain barrier (BBB). The interest has been expressed in the use of the nasal route for delivery of AVP to the brain directly, exploiting the olfactory pathway. Our previous study(More)
To detect early changes in neurons and astrocytes by immunohistochemical methods using antibodies against the neuron-specific enolase (NSE), neurofilament, glial fibrillary acid protein (GFAP), and S-100 protein, a fluid-percussion injury model in cats was chosen, in which a severe grade of injury (3.5-5.5 atm) was produced. Neuropathologic changes were(More)
