BACKGROUND The molecular mechanism of propofol anesthesia has been related to facilitation of the inhibitory neurotransmission mediated by gamma-aminobutyric acid (GABA). In the current study, the authors examined the direct actions of propofol on the acutely dissociated mammalian central neurons. METHODS Hippocampal pyramidal neurons were dissociated(More)
BACKGROUND Activation of the gamma-aminobutyric acidA (GABAA) receptor-ionophore complex has been reported as a possible molecular mechanism of the anesthetic action of propofol. Augmentation of GABA-induced inhibitory transmission has also been suggested as a mechanism. Because data describing this latter mechanism in mammalian neurons are few, we have(More)
Serum cytokine and chemokine levels were examined in mice following 36 h of sleep deprivation, or after exposure to a known physical stressor (rotational stress). Significant changes in inflammatory cytokines/chemokines (IL-1beta, TNFalpha, IL-1ra, IL-6, and MIP-1beta, MCP-1) were observed following each manipulation, but qualitative and quantitative(More)
Asthma is associated with increased numbers of T-cells in the lung. CC chemokine receptor (CCR)5 and CXC chemokine receptor (CXCR)3 have been reported to play important roles in the lung T-cell homing pathway, and may be potential targets for asthma therapy. The aim of the present study was to investigate the role of CCR5 and CXCR3 in allergen-induced acute(More)
Alport syndrome is a hereditary glomerulopathy with proteinuria and nephritis caused by defects in genes encoding type IV collagen in the glomerular basement membrane. All male and most female patients develop end-stage renal disease. Effective treatment to stop or decelerate the progression of proteinuria and nephritis is still under investigation. Here we(More)
The effects of local anesthetics on amino acid-induced currents were examined using the whole-cell configuration of the patch clamp technique in dissociated hippocampal pyramidal neurons of the rat. Lidocaine (3 mM) decreased the glycine-induced Cl- current (Gly-ICl) more potently (to 46% of the control value) than the gamma-aminobutyric acid-induced Cl-(More)
1) Electrical membrane properties of spread type-osteoclasts were examined using the whole-cell and cell-attached configurations of the patch clamp technique. The membrane potential of the osteoclasts was measured and grouped into two populations: hyperpolarized and depolarized (around -80 and 0 mV, respectively). The current-voltage relation was N-shaped,(More)
The oral glucose tolerance test and arginine infusion test were carried out on 22 patients with chronic pancreatitis and 11 normal control subjects. According to the glucose tolerance curve, the patients were divided into three groups; group I (normal or slightly impaired), group II (mildly diabetic) and group III (moderately diabetic). Markedly impaired(More)
