Elevation of corticosteroids and excessive glutamate release are the two major stress responses that occur sequentially during traumatic CNS injury. We have previously reported that sequential application of corticosterone and kainic acid (CORT + KA) mimicking the nerve injury condition results in synergistic enhancement of neurite outgrowth and expression(More)
PURPOSE To evaluate the potential effect of a clinically relevant concentration of propofol (PPF) on cell viability and nitric oxide-induced macrophage apoptosis. METHODS Mouse macrophages (cell line Raw 264.7) were cultured and incubated with a nitric oxide donor sodium nitroprusside (SNP), PPF, and a combination of PPF and SNP for one, six and 24 hr.(More)
Our previous study identified a vincristine-selected multidrug resistance (MDR) cell line, HOB1/VCR, derived from a lymphoblastoma HOB1. The HOB1/VCR cells are resistant to typical MDR drugs and are cross-resistant to P-glycoprotein-independent drugs such as cisplatin (cis-diamminedichloroplatinum [II]). The mechanism of this atypical MDR phenotype is(More)
Recent epidemiological studies have shown that dioxin, a persistent organic pollutant, is related to cognitive and behavioral abnormalities in the offspring of exposed cohort. In order to investigate the possible impact of dioxin in survival gene expression during brain development, we established an animal model of gestational and lactational(More)
BACKGROUND Glutamate and glutamate transporters (GTs) (including glutamate/aspartate transporter, glutamate transporter-1, and excitatory amino acid carrier 1) have important roles in the pathogenesis of ischemic neurological injury. The changes in glutamate, GTs, and neuronal injury after subarachnoid hemorrhage (SAH) have not been widely investigated. In(More)
INTRODUCTION Human dental pulp stem cells (DPSCs) have been reported to be useful material for future regenerative medicine. Clinically, cryopreservation of intact teeth can successfully preserve the periodontal ligament for future autotransplantation; however, the effects of cryopreservation procedure on the properties of DPSCs are still unclear. The aim(More)
We previously demonstrated the antiproliferative and antiangiogenic effects of 3-methylcholanthrene (3MC), an aryl-hydrocarbon receptor (AhR) agonist, in human umbilical vascular endothelial cells (HUVECs). Herein, we unraveled its molecular mechanisms in inhibiting HUVEC motility. 3MC down-regulated FAK, but up-regulated RhoA, which was rescued by AhR(More)
Reactive gliosis caused by post-traumatic injury often results in marked expression of chondroitin sulfate proteoglycan (CSPG), which inhibits neurite outgrowth and regeneration. Methylprednisolone (MP), a synthetic glucocorticoid, has been shown to have neuroprotective and anti-inflammatory effects for the treatment of acute spinal cord injury (SCI).(More)
The present study examined the effects of BIOCERAMIC on psychological stress-conditioned elevated heart rate, blood pressure and oxidative stress-suppressed cardiac contractility using in vivo and in vitro animal models. We investigated the effects of BIOCERAMIC on the in vivo cardiovascular hemodynamic parameters of rats by monitoring their heart rates,(More)
Electroacupuncture (EA) is a complementary therapy to improve morphine analgesia for postoperative pain, but underlying mechanism is not well-known. Herein, we investigated EA-induced analgesic effect in a plantar incision (PI) model in male Sprague-Dawley rats. PI was performed at the left hind paw. EA of 4 Hz and high intensity or sham needling was(More)
