OBJECTIVES The purpose of the present study was twofold: 1) to evaluate the usefulness of three-dimensional (3D) integrated backscatter (IB) intravascular ultrasound (IVUS) for quantitative tissue characterization of coronary plaques; and 2) to use this imaging technique to determine if six months of statin therapy alters the tissue characteristics of(More)
We examined a possible preventive effect of Linderae radix (LR), the root of Lindera strychnifolia, on the progression of diabetic nephropathy. Water extract of Linderae radix (LR extract) was orally administered to the C57BL/KsJ-db/db (db/db) mice, a model of genetic diabetes, at a dose of 730 mg/kg/day for 12 week. The LR extract treatment did not affect(More)
BACKGROUND The mechanism of glomerular cell loss during the late stage of diabetic nephropathy is unknown. METHODS We examined cell population, proliferation, apoptosis, and immunohistochemical expression of apoptosis-related proteins, Bcl-2 and Bax, in renal glomeruli of the Otsuka Long-Evans Tokushima Fatty (OLETF) rat, an animal model of human type 2(More)
Angiotensin converting enzyme inhibitors (ACE-Is) and angiotensin II receptor blockers (ARBs) are frequently used for the treatment for glomerulonephritis and diabetic nephropathy because of their albuminuria- or proteinuria-reducing effects. To many patients who are nonresponsive to monotherapy with these agents, combination therapy appears to be a good(More)
Unique autoantibody was found in sera from two different patients that reacted with centrioles of both cultured mammalian cells and human peripheral leukocytes as detected by the indirect immunofluorescent method. Sera from the same individuals, one with scleroderma and the other suffering from Raynaud's phenomenon, also stained the basal bodies of rat(More)
1. In the present study, we examined the effects of inhibiting transforming growth factor (TGF)-beta in a mouse model of diabetic nephropathy. 2. An adenovirus harbouring the gene encoding soluble TGF-beta type II receptor (Ad.CAG-sTbetaRII), a competitive inhibitor of TGF-beta, was injected into hindlimb muscles (systemic delivery) of mice 5 weeks after(More)
BACKGROUND Autopsy studies have shown atherosclerotic changes in angiographically normal coronary lesions (ANCL), and conventional intravascular ultrasound shows intimal thickening in these lesions, but cannot differentiate the lipid core. Accurate characterization of ANCL is essential to prevent progression to coronary artery disease. METHODS AND RESULTS(More)
BACKGROUND Effect of hepatocyte growth factor (HGF) has scarcely been determined on diabetic nephropathy. METHODS Adenovirus encoding human HGF gene or LacZ gene (as the control) was injected into the hindlimb muscles of the C57BL/KsJ-db/db (db/db) mice at the age of 12 weeks, a model of genetic diabetes. Diabetic nephropathy was then evaluated at the age(More)
OBJECTIVE To evaluate the immediate effects of traditional local thermal therapy with indirect moxibustion on renal hemodynamics in patients with chronic kidney disease (CKD) by using Doppler ultrasonography (US). DESIGN Examiner-blinded crossover study. PARTICIPANTS Forty-three participants with CKD (mean age ± standard deviation [SD], 44 ± 15 years;(More)
AIMS We investigated the relationship between levels of plasma soluble Fas (sFas) and stages of diabetic nephropathy, with special reference to apoptosis and clinical features of diabetic nephropathy in 168 patients with diabetic nephropathy. RESULTS There was a positive correlation between plasma sFas and creatinine levels, between sFas levels and(More)
