Delirium occurs in 23% of sepsis patients, in which pro-inflammatory cytokines and nitric oxide are suggested to be involved. However, in animal experiments, even a subseptic dose of lipopolysaccharide (LPS) injection induces both pro-inflammatory cytokines and inducible nitric oxide synthase in the brain, suggesting that the brain oxidative reaction can be(More)
Accumulation, transformation and toxicity of arsenic compounds to Japanese Medaka, Oryzias latipes were investigated. For sodium arsenite [As(II)] and disodium arsenate [As(V)], the mean value for 7-day lethal concentration LC50 for O. latipes were 14.6 and 30.3 mg As/l, respectively. Direct accumulation of arsenic in O. latipes increased as a function of(More)
BACKGROUND Clonidine, an alpha-2 adrenoceptor agonist, is a common adjunct in both central and peripheral blocks. Dexmedetomidine, a more selective alpha-2 adrenoceptor agonist, is also known to enhance central neural blockades. Its peripheral effect, however, has not been fully elucidated. Thus, we evaluated the effect of dexmedetomidine and other alpha-2(More)
STUDY OBJECTIVE To investigate the use of propofol sedation using Bispectral Index (BIS)-guided target-controlled infusion (TCI) in dental patients with intellectual disability. DESIGN Single-center, prospective, randomized clinical trial. SETTING Academic outpatient clinic. SUBJECTS 40 ASA physical status 1 and 2 patients with intellectual(More)
A case of mesenteric varices draining into the left renal vein is reported. The varices were well demonstrated by percutaneous transhepatic portography and were obliterated. This disease entity should be considered in the differential diagnosis of patients with lower gastrointestinal tract hemorrhage and portal hypertension.
Iron is known to be involved in neuronal diseases such as neurodegenerative diseases, brain ischemia and epilepsy. However, it is unclear if a high level of peripheral iron induces these pathological conditions. Since ferric nitrilotriacetate (Fe-NTA), a low molecule iron chelate, causes kidney carcinoma and diabetes in animals due to its strong and unique(More)
Angioedemas are a rare but significant event in simple oral surgery because they can cause an acute life-threatening laryngeal edema. We report a case of a tooth extraction in a patient with hereditary angioedema, for which the C1-inhibitor (C1-INH) concentration administered effectively controlled edema during and after extraction. We also review case(More)
Adrenaline (epinephrine) is included in dental local anesthesia for the purpose of vasoconstriction. In Japan, adrenaline is contraindicated for use in patients receiving antipsychotic therapy, because the combination of adrenaline and an antipsychotic is considered to cause severe hypotension; however, there is insufficient evidence supporting this claim.(More)
The oral administration of midazolam has often been used for sedation in pediatric patients. However, oral administration of an intravenous formulation of midazolam is difficult for younger pediatric patients because of its bitter taste. Liposomes have been developed as vesicles encapsulating various kinds of drugs to serve as a medical drug-delivery(More)
Hemorrhagic shock (HS) is an oxidative stress that causes intestinal tissue injury. Heme oxygenase 1 (HO-1) is induced by oxidative stress and is thought to play an important role in the protection of tissues from oxidative injury. We previously reported the ileum to be the most susceptible to HS-induced tissue injury site in the intestine because HO-1(More)
