Paraoxonase-1 (PON1) is an HDL cholesterol-associated antioxidant enzyme, and some of its polymorphisms are linked with systemic oxidative stress and cardiovascular events. In this study, we genotyped seven single nucleotide polymorphisms (SNPs) within the PON1 gene and determined their association with chronic kidney disease in 2,968 individuals from the(More)
BACKGROUND Microalbuminuria, a marker of vascular damage, is associated with increased risk of progressive renal deterioration, cardiovascular disease and mortality. However, the relationship between antinuclear antibody (ANA) and microalbuminuria in the general population is unknown. Thus, we conducted a cross-sectional study to examine the relationship(More)
BACKGROUND Glomerular and tubular damage are important factors in the development of renal insufficiency. However, the interaction of these factors is largely unknown in the non-diabetic Japanese population. To clarify the relationship between renal insufficiency and both glomerular and tubular damage, we conducted a community-based study using albuminuria(More)
Microalbuminuria, an indicator of glomerular injury, is associated with increased risk of progressive renal deterioration, cardiovascular disease, and mortality. However, the prevalence of microalbuminuria in Japanese general population is less certain. Thus, we examined the prevalence of microalbuminuria and its associated risk factors in Japan.

Several studies have suggested that hypertriglyceridemia is a common risk factor for coronary heart disease. Although increasing serum levels of triglyceride correlate with hypercoagulability, little is known about the contribution of hypertriglyceridemia to vascular function. We successfully segregated two lines of rabbits with genetically-determined(More)
BACKGROUND The urine dipstick test that regards > 1+ proteinuria as positive is unsuitable for microalbuminuria screening owing to its low sensitivity in the general population. We conducted a cross-sectional survey to examine whether trace proteinuria could be an indicator of microalbuminuria. METHODS The subjects were 2321 participants in a(More)
For a better understanding of the formal pathogenesis of liver cirrhosis, the angioarchitecture of the liver lobule in chronic viral hepatitis was investigated three dimensionally. The histological reconstruction method, using serial histological sections, was adopted for the three-dimensional observation. Histology of the case showed chronic active(More)
BACKGROUND/AIMS We examined the three-dimensional structures of the hepatic artery. MATERIALS/METHODS A 39-year-old man who died of brain hemorrhage was autopsied. The liver was perfused with physiological saline and 20% formalin from the hepatic artery and portal vein. More than 700 serial sections were obtained from a paraffin-embedded block, and(More)
BACKGROUND The renin-angiotensin-aldosterone system plays a pivotal role in regulation of blood pressure and electrolyte homeostasis and is a target in the treatment of hypertension and renal diseases. However, the factors correlated with plasma renin activity (PRA) are unclarified in general Japanese population. To examine this point, we conducted a(More)
BACKGROUND Injury to renal tubules plays an important role in the development of various renal diseases; however, the prevalence and significance of renal tubular damage in the general population are unclear. To clarify this point, we conducted a community-based study, using urinary β(2)-microglobulin as a marker of tubular damage. METHODS The subjects(More)
