The presence of Helicobacter pylori (H. pylori) in the stomach is closely associated with histological signs of chronic active gastritis and peptic ulcer. Another spiral organism named Gastrospirillum hominis (G. hominis) has led to further interest in the bacterial pathogenesis of gastritis. Due to the low prevalence of G. hominis, it is difficult to(More)
In order to evaluate the changes in uterine oxytocin receptor-specific mRNA during pregnancy, receptor expression in Xenopus oocytes are examined electrophysiologically following microinjection of mRNA from human uterus. In voltage-clamped oocytes injected with term myometrial mRNA, oxytocin elicited an inward current response. The amplitude of the(More)
The oxidation of rat red blood cells (RBC) by molecular oxygen was performed in an aqueous suspension with an azo compound as a free-radical initiator. The RBC were oxidized at a constant rate by a free-radical chain mechanism, resulting in hemolysis. The extent of hemolysis was proportional to the concentration of free radical. alpha-Tocopherol in RBC(More)
Color Doppler flow imaging was performed in 121 patients with portal hypertension. Portosystemic collateral shunts originating from the left portal veins were seen in 41 of the patients. A single collateral shunt was seen in 27 of these, and multiple collateral shunts were seen in the other 14. Collateral shunts running in the ligamentum teres were seen in(More)
It has been demonstrated that the level of serum copper unbound to ceruloplasmin (loosely bound copper) is increased in Wilson's disease, although the total serum copper concentration is usually low, reflecting a low ceruloplasmin level. To assess the contribution of free radical reactions catalyzed by nonceruloplasmin copper to the development of(More)
Acute toxicity of individual PCBs, which were categorized as either phenobarbital (PB)- or 3-methylcholanthrene (MC)-type inducers, was examined in young male Wistar rats, comparing their effects on growth rate, organ weight and liver lipid content, 5 days after a single i.p. injection. PB-type PCBs (2,4,3',4'- and 2,5,2'5'-tetrachlorobiphenyl), which(More)
The prevalence of Helicobacter pylori infection is high among Asian populations, but the incidences of gastric cancer differ greatly among northern and southern Asian populations. Here, we studied histopathological findings in stomach tissue using an updated Sydney System and the frequencies of interleukin (IL)-1betapolymorphisms, thought to be associated(More)
OBJECTIVE Severe congenital neutropenia (SCN), also known as Kostmann syndrome (SCN3, OMIM 610738), includes a variety of haematological disorders caused by different genetic abnormalities. Mutations in ELA2 are most often the cause in autosomal dominant or sporadic forms. Recently, mutations in HAX1 have been identified as the cause of some autosomal(More)
Intercellular adhesion molecule 1 (ICAM-1) plays an important role in the pathogenesis of insulin-dependent diabetes mellitus (IDDM) by being involved in the extravasation of lymphocytes from the circulation into the inflamed pancreas. However, the mechanism of beta-cell destruction by which expression of ICAM-1 on beta-cells may facilitate adhesion of(More)
The authors investigated long-term outcome and treatment strategy of corticosteroid-induced psychotic and mood disorders as defined by DSM-IV. Review of medical records of 2,069 referral patients revealed 18 applicable patients. Their clinical characteristics, longitudinal courses, and treatments were studied. The authors identified 15 patients with mood(More)
