Prognostic impact of aortic calcification index and ankle-arm blood pressure index in patients under hemodialysis.

The mortality rate is high in patients receiving hemodialysis (HD), atherosclerotic diseases being the major cause of death. As marker of clinical outcome, a prospective examination of atherosclerotic tests and atherosclerotic risk factors in patients receiving HD was performed. On April 2000, 84 patients receiving HD were followed up until April 2002.

Effects of atorvastatin on serum lipids, lipoproteins, and hemostasis.

Serum levels of lipids and lipoproteins were examined in individuals with hyperlipidemia treated with atorvastatin or colestimide and in healthy volunteers. Modified low-density lipoprotein (LDL) was measured by its faster electrophoretic mobility and expressed as charge modification frequency (CMF). Serum levels of total cholesterol (t-chol), triglyceride (TG), very low-density lipoprotein (VLDL)-chol, low-density lipoprotein (LDL)-chol, and CMF were significantly higher in hyperlipidemia, but there was no significant difference in serum high-density lipoprotein (HDL)-chol levels between hyperlipidemic and healthy subjects.

Effects of lipid abnormalities on arteriosclerosis and hemostatic markers in patients under hemodialysis.

Vascular events caused by arteriosclerosis are the major cause of death in patients under hemodialysis (HD). Arteriosclerosis is associated with lipoprotein abnormalities such as increased serum levels of low-density lipoprotein (LDL), especially of modified LDL (M-LDL) and oxidized LDL (Ox-LDL). We examined the relationship between markers of arteriosclerosis, hemostasis, and lipid metabolism in patients with chronic renal failure, hyperlipidemia, and healthy volunteers.

Good or poor responses of hemostatic molecular markers in patients with hematopoietic disorders after treatment of disseminated intravascular coagulation.

Changes of hemostatic markers in 226 patients with disseminated intravascular coagulation (DIC) and hematopoietic disorders were examined after treatment of DIC. The changes in prothrombin time (PT) ratio, fibrinogen, fibrin and fibrinogen degradation products (FDP), antithrombin, and protein C, thrombin-antithrombin complex (TAT), plasmin-plasmin inhibitor complex (PPIC), and soluble fibrin monomer complex (SFMC) in all patients with DIC were significant during the clinical course of DIC, but those of D-dimer, thrombomodulin (TM), tissue factor (TF), and tissue factor pathway inhibitor (TFPI) were not. Activated partial thromboplastin time (aPTT) and PT were significantly longer in the poor response group than in good response group.

Expression of tissue factor and vascular endothelial growth factor is associated with angiogenesis in colorectal cancer.

We examined the expression of tissue factor (TF) and vascular endothelial growth factor (VEGF) and the microvessel density (MVD) in 100 patients with colorectal cancer, and we investigated the relationship of the expression of TF or VEGF with angiogenesis. TF antigen was positive in 57.0% of all specimens.
