Essential hypertension has a genetic basis. Accumulating evidence, including findings of elevation of arterial blood pressure in mice lacking the endothelial nitric oxide synthase (eNOS) gene, strongly suggests that alteration in NO metabolism is implicated in hypertension. There are, however, no reports indicating that polymorphism in the eNOS gene is(More)
Hematopoietic function of some aplastic anemia (AA) patients is dependent on the administration of cyclosporine (CyA). To investigate whether certain HLA class II genes are associated with susceptibility to such CyA-dependent AA, we determined the HLA class II alleles of 59 AA patients treated with CyA. Among 26 patients successfully treated with CyA, 13(More)
Ferric chloride, when boiled with hydrazine hydrate and cacodylic acid, is converted into a fine cationic iron (ferric hydroxide) colloid which consists of 0.5-1.5 nm electron-dense granules, and gives a distinct Prussian blue reaction. This colloid allows light and electron microscopic detection of ionized anionic sites in tissues at a wide pH range of(More)
BACKGROUND The diagnostic sensitivity of myocardial necrosis markers, such as creatine kinase-MB (CK-MB), cardiac troponins, myoglobin and heart-type fatty acid-binding protein (H-FABP) for the earliest stage of ST-elevation myocardial infarction (STEMI), remains insufficient. We compared a new biomarker of plaque vulnerability (soluble lectin-like oxidized(More)
It is unclear how a paroxysmal nocturnal hemoglobinuria (PNH) clone expands in bone marrow, although immune mechanisms involving cytotoxic T lymphocytes, autosomal proliferation, and apoptosis resistance have been hypothesized. To clarify aspects of immune mechanisms and proliferation of PNH cells, we investigated HLA-DRB1, -DQA1, and -DQB1 alleles by(More)
This paper investigates the presence of HLA class I-restricted and tumor-specific cytotoxic T lymphocytes (CTL) in tumor sites of esophageal cancers. Five CTL lines were established from the metastatic lymph nodes or pleural effusion by incubation with interleukin-2 of tumor-infiltrating lymphocytes: cases 1 and 5, HLA-A26- and HLA-A33-restricted and(More)
The human leukocyte antigen is a crucial genetic factor that initiates or regulates immune response by presenting foreign or self antigens to T lymphocytes. The aim of this study was to investigate whether HLA polymorphism is associated with the onset or progression of liver injury in chronic hepatitis C virus (HCV) infection. We determined HLA class I(More)
BACKGROUND We recently identified two endothelial nitric oxide synthase (eNOS) gene polymorphisms, Glu298Asp and T-786-->C, which are independently associated with coronary spasm. eNOS gene intron 4b/a polymorphism is also reported to be involved in smoking-dependent coronary artery disease. The genetic linkage among these polymorphisms remains unknown.(More)
Masugi nephritis was induced in Sprague-Dawley rats by an intravenous injection of rabbit anti-rat kidney serum. In the autologous phase of the disease, three of 18 rats manifested continuous hematuria. Ultrastructural examination of renal glomeruli by transmission and scanning microscopy revealed gaps in the basement membranes, and the transcapillary(More)
Bile duct injury can occur more frequently during laparoscopic cholecystectomy than in open cholecystectomy. Three cases of common bile or hepatic duct injuries occurred in a series of eighty laparoscopic cholecystectomies; In case 1, the common bile duct was misidentified as the cystic duct. In case 2, bile peritonitis occurred on the fourth postoperative(More)
