To investigate fructose concentrations in diabetic patients with ketoacidosis or ketosis, serum fructose concentrations and daily urinary fructose excretion were measured in 23 patients with ketoacidosis (n = 16) and ketosis (n = 7) on the first day of admission. Seventeen patients were diagnosed with type 1, one patient with mitochondrial, and 4 patients(More)
AIMS To compare the metabolic effects of pioglitazone, metformin, and glimepiride in the treatment of Japanese patients with newly diagnosed Type 2 diabetes. METHODS A total of 114 patients with Type 2 diabetes who had never used oral hypoglycaemic drugs were studied for 12 months. Patients were randomly assigned to pioglitazone (30-45 mg/day, n = 38),(More)
UNLABELLED Myocardial kinetics of 123I-labeled 15-(p-iodophenyl)3R, S-methylpentadecanoic acid (BMIPP) were evaluated with dynamic SPECT, and stress and rest BMIPP images were directly compared in conjunction with stress 201Tl. METHODS We studied 26 patients with prior myocardial infarction. Two minutes after injection of BMIPP, dynamic data acquisition(More)
Using both cross-sectional and longitudinal methods, we investigated the relationship between post-load serum glucose concentration in a 75 g oral glucose tolerance test (OGTT) and overall glycaemic state in subjects with impaired glucose tolerance (IGT). Glycaemic state was assessed by measuring glycated haemoglobin (HbA1c) and the serum concentration of(More)
The aim of the present study was to investigate the association of fructose on microangiopathy in patients with diabetes. Postprandial plasma fructose concentrations and postprandial plasma glucose concentrations were simultaneously measured 3 times within a 24-hour period (2 hours after each meal) in 38 patients with type 2 diabetes that had been admitted(More)
UNLABELLED This study was performed to test the feasibility of early SPECT imaging with 99mTc-tetrofosmin with the presence of high hepatic activity. METHODS Thirteen normal volunteers were injected 600-740 MBq of 99mTc-tetrofosmin at rest and were imaged at 10 min and 1 hr after injection. The SPECT images were reconstructed for 180 degrees 360 degrees(More)
Concentrations of 1,5-anhydroglucitol (1,5-AG), which is a major circulating polyol, decrease in patients with diabetes mellitus. In both insulinoma-derived RINr and MIN6 cells, 1,5-AG stimulated insulin release within the range of 0.03-0.61 mM in a dose-dependent manner. Insulin release was maximally stimulated by 1,5-AG to levels that reached 25% and 100%(More)
Exercise-reinjection 201Tl imaging and resting 20-min and 3-hr BMIPP imaging were performed before and 4 mo after percutaneous transluminal coronary angioplasty (PTCA) in a patient with effort angina. Before PTCA, exercise 201Tl imaging showed decreased 201Tl activity in the septal wall, with significant fill-in on the reinjection 201Tl image. The resting(More)
