The action of dexmedetomidine on rat locus coeruleus neurones was examined using intracellular recordings from the in vitro brain slice preparation. Concentrations of dexmedetomidine from 1 to 1000 nM were tested. At 30 nM, dexmedetomidine produced complete inhibition of firing of all neurones tested (n = 21); this was associated with a 13 mV(More)
Increasing evidence has demonstrated that nitric oxide (NO) is involved in central cardiovascular regulation. In this study, we directly measured extracellular NO levels, in real-time, in the nucleus tractus solitarius (NTS) of anesthetized cats using Nafion/Porphyrine/o-Phenylenediamine-coated NO sensors. We found that local application of L-arginine(More)
The purpose of this study was to investigate the regulation of dopamine (DA) release and clearance by Substance P (SP) in striatum. In vivo high speed chronoamperometric recording techniques, with Nafion-coated carbon-fiber electrodes, were used to evaluate extracellular DA concentrations in urethane-anesthetized Sprague-Dawley rats. SP was locally applied(More)
We have previously reported that grafting of fetal ventral mesencephalic (VM) tissue to the nigral region of unilaterally 6-hydroxydopamine (6-OHDA)-lesioned rats, in conjunction with glial cell line-derived neurotrophic factor (GDNF) injection between nigra and striatum, restores nigrostriatal tyrosine hydroxylase (TH) immunoreactivity. In this study, we(More)
To evaluate the effect of the different doses of antithymocyte globulin (ATG) on the incidence of acute GVHD among patients receiving hematopoietic SCT without ex vivo T-cell-depletion from haploidentical donors, 224 patients with standard-risk hematological malignancy were randomized in this study. One hundred and twelve patients received 6 mg/kg ATG,(More)
BACKGROUND Introducing evidence-based exercise guidelines of Parkinson's disease (PD) into clinical practice and community settings has been highlighted. AIM This study tested the feasibility and compared the weekly effects of a 12-week walking training program on PD patients and community-dwelling seniors. DESIGN A prospective quasi-experimental design(More)
In the present study, we compared the changes in dopamine (DA) release and clearance in the striatum after unilateral 6-hydroxydopamine (6- OHDA) lesioning of the nigrostriatal DA pathway in urethane-anesthetized rats. High-speed in vivo chronoamperometric recording techniques using Nafion-coated carbon fiber electrodes were used to evaluate extracellular(More)
