LC/MS/MS evaluation of cocaine and its metabolites in different brain areas, peripheral organs and plasma in cocaine self-administering rats.
Journal Title: Pharmacological Reports - Year 2012, Vol 64, Issue 6
Abstract
We employed a cocaine intravenous self-administration model based on positive reinforcement of animals' instrumental reactions (i.e., lever pressing) rewarded by a dose of the drug. We also carried out simultaneous characterization of the pharmacokinetics of cocaine and its metabolites in rats during withdrawal; in this part of the experiments, we investigated the cocaine (2 mg/kg, iv)-induced changes in the distribution, rate constant, clearance and t₁/₂ of the parent drug and its metabolites in different structures of the brain and in peripheral tissues.

Effect of an NMDA receptor agonist on T-maze and passive avoidance test in 12-week streptozotocin-induced diabetic rats.
This study examined behavioral effects mediated by NMDA (N-methyl-D-aspartic acid) receptors in 12-week streptozotocin (STZ)-induced diabetic rats. Effects of an NMDA receptor agonist on behavior in the open field test,...
Restoration of immune system function is accelerated in immunocompromised mice by the B-cell-tropic isoxazole R-11.
Background: Restoration of impaired immune response in immunocompromised patients is a crucial problem. In this study we evaluated the efficacy of isoxazole R-11 in reconstitution of the immune response in immunosuppress...
Cerebral oligemic hypoxia and MK-801 treatment: effect on alternation behavior in mice.
It is known that glutamatergic system is one of neurotransmitter systems affected by a transiently reduced oxygen supply. The aim of the present study was to examine the effects of MK-801, a noncompetitive NMDA receptor...
Simvastatin inhibits the increase in serum tau protein levels in the acute phase of ischemic stroke.
Our goal was to analyze the effects of treatment with a 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitor (simvastatin, 40 mg/day) on serum S100BB and tau protein levels during the acute ischemic stroke...
Detrimental effect of postnatal blockade of N-methyl-D-aspartate receptors on sensorimotor gating is reversed by neuroleptic drugs.
Postnatal hypofunction of N-methyl-D-aspartate (NMDA) receptors leads to several behavioral deficits in adult rats resembling deficits typical of schizophrenia-like deficits of sensorimotor gating. Thus far, it is not kn...
