OBJECTIVE Helicobacter pylori infection and atrophic gastritis are inversely related to erosive esophagitis. Whether these factors affect the pathogenesis of endoscopy-negative reflux disease is not clear. We aimed to elucidate the differences in clinical characteristics between endoscopy-negative erosive disease and erosive esophagitis. METHODS 253(More)
Mutation in the mitochondrial gene at position 3243 was recently identified in a large pedigree of diabetes mellitus and deafness. As the mitochondria play an important role in glucose-stimulated insulin secretion in pancreatic beta-cells, we therefore searched for such mutations to detect a candidate gene for diabetes. We screened 10 diabetic subjects with(More)
The aim of the present study was to evaluate rebamipide in the prevention of indomethacin-induced gastric mucosal injury in healthy volunteers. Twenty healthy males (mean age 21.8 years, range 20-26) participated. This is a randomized, double-blind, placebo-controlled study. The 20 subjects were randomized to either indomethacin 25 mg three times a day and(More)
The preventive effect of Oren-gedoku-to (Huanglian-Jie-Du-Tang) extract (TJ-15), a traditional Chinese herbal medicine for the therapies of gastric ulcers and gastritis, on the development of stress-induced acute gastric mucosal lesions was examined in rats with water immersion restraint (WIR) stress. Simultaneous p.o. administration of TJ-15 at a dose of(More)
This study attempted to determine whether postprandial hypotension (PPH) is associated with diabetes mellitus by 24-h ambulatory blood pressure monitoring (24-h ABPM) and by monitoring blood pressure during 75-g oral glucose tolerance test (75-g OGTT) in 15 normal subjects and 35 patients with non-insulin-dependent diabetes mellitus. When we defined PPH as(More)
The effect of trypsin treatment on the mode of L-tryptophan uptake (L- and T-transport systems) into hepatocytes was investigated in comparison with that of L-leucine (L-type system) using isolated rat hepatocytes. L-Tryptophan uptake occurred via at least two saturable (one high-affinity and one low-affinity) and one non-saturable components in intact(More)
Lymphatic transport of alpha-, gamma- and delta-tocotrienols and alpha-tocopherol was measured in thoracic duct-cannulated rats. Animals were administered 3 ml of a test emulsion containing 200 mg sodium taurocholate, 50 mg fatty acid free-albumin, 200 mg fat and 100 mg of a mixture of tocotrienols and alpha-tocopherol (Exp. 1) or 10 mg of purified alpha-,(More)
Activator protein-1 (AP-1), a transcription factor, is activated through many oncogenic signals. However, its biological role in colorectal cancer has not been fully elucidated. To investigate the role of AP-1 in colorectal cancer, we constructed an adenovirus-expressing TAM67, a dominant-negative mutant of c-Jun lacking the transactivation domain of wild(More)
The change in hepatic antioxidant defense system with the development of alpha-naphthylisothiocyanate (ANIT)-induced liver injury was examined in rats injected once with the toxicant (75 mg/kg body weight). Liver injury with cholestasis did not occur 12 h after ANIT injection, but appeared at 24 h, progressed at 48 h, and recovered at 72 h, judging from the(More)
An association between lipid peroxidation and alpha-naphthylisothiocyanate (ANIT)-induced liver injury was examined in rats injected once with the toxicant (75 mg/kg body weight). The severity of liver injury was estimated 12, 24, 48, and 72 h after ANIT injection. Liver injury appeared 24 h after ANIT injection, progressed at 48 h, and recovered at 72 h,(More)
