BACKGROUND The neurotransmitters dopamine and glutamate have been implicated in the prefrontal dysfunction associated with schizophrenic illness. Studies suggest that the D1 subclass of dopamine receptor and the N-methyl-D-aspartate subclass of glutamate receptor are involved in this prefrontal dysfunction. These 2 receptors regulate, in opposing(More)
BACKGROUND Protein kinase C (PKC) has been implicated as a target for general anesthetic action in the central nervous system. Previous reports have described either stimulation or inhibition of PKC activity by general anesthetics. This study examines the effects of halothane and propofol on the activity of purified rat brain PKC under various assay(More)
BACKGROUND Inhalational anesthetics are neuroprotective in rat models of global ischemia. To determine whether isoflurane at a clinically relevant concentration is neuroprotective in a canine model of cardiac arrest, we measured neurologic function and hippocampal Ca2+/calmodulin-dependent protein kinase II (CaMKII) content 20 h after cardiac arrest.

BACKGROUND Protein kinase C is a signal transducing enzyme that is an important regulator of multiple physiologic processes and a potential molecular target for general anesthetic actions. However, the results of previous studies of the effects of general anesthetics on protein kinase C activation in vitro have been inconsistent. METHODS The effects of(More)
Protein kinase C (PKC) is a key regulatory enzyme that has been implicated as a molecular target for the action of general anaesthetics. We have determined the effects of halothane on the translocation and down-regulation of conventional PKC (cPKC) by analysing the subcellular distribution of PKC activity, [3H]phorbol-12,13-dibutyrate ([3H]PDBu) binding and(More)
Halothane and propofol stimulate activation of protein kinase C (PKC) in the presence of physiologically relevant lipid bilayer vesicles in vitro. The mechanism of this stimulation was characterized by analyzing the effects of halothane and propofol on the activation of purified rat brain PKC by its three essential activators, phosphatidylserine,(More)
