    Notes: This study reports hydrogen absorption property of newly-synthesized RAP(rubeanic-acid polymer)-protected palladium nanoparticle (RAP-Pd). From powder X-ray diffraction measurements, the lattice constant of Pd nanoparticle was revealed to increase by 0.11 Å under 600 Torr hydrogen gas condition at room temperature, indicating that the hydrogen absorption occurs in the Pd nanoparticle. Solid-state 2H-NMR spectrum under deuterium gas showed that three different components exist in RAP-Pd, which are derived from imino group, terminal amino group in the RAP and absorbed deuterium atom inside the Pd nanoparticle. Thisresult gives an expectation of the hydrogen absorption in RAP itself

    Notes: Summary To elucidate the risk factors for initiating glucose intolerance, the relevant factors were explored in a cross-sectional survey conducted in a sample population aged 40–79 years old selected from a Japanese community, Hisayama, Japan in 1988. A 75-g oral glucose tolerance test was used to classify 1,073 men (72.5 % of the entire population in the same age range) and 1,407 women (80.5 %) into normal, impaired glucose tolerance and diabetes mellitus groups. In all age and sex groups with normal glucose tolerance, the sum of fasting and 2-h post-load insulin values varied widely and demonstrated significant positive correlations with triglycerides, body mass index, waist-hip ratio, systolic and diastolic blood pressure, while it negatively correlated to HDL cholesterol (p 〈 0.05). Insulin resistance was presumed to develop in normal glucose tolerance subjects with hyperinsulinaemia. The sum of the insulin concentrations, triglycerides, body mass index, waist-hip ratio and blood pressure levels was significantly associated with impaired glucose tolerance in all age and sex groups after adjustment for age (p 〈 0.05) and was also related to diabetes in either all or some age and sex groups, respectively (p 〈 0.05). It was shown that glucose intolerance in the general population was associated with the factors related to insulin resistance. These cross-sectional data, therefore, support the hypothesis that insulin resistance is the primary defect in the development of glucose intolerance in the Japanese general population. However, a further prospective study is still needed in order to confirm this hypothesis. [Diabetologia (1994) 37: 897–904]

    Notes: Summary The relationship between diabetic nephropathy and an insertion (I)/deletion (D) polymorphism in intron 16 of the angiotensin-converting enzyme (ACE) gene is still under debate. The association of ACE gene polymorphism with nephropathy and retinopathy was therefore examined in 362 Japanese patients with non-insulin-dependent diabetes mellitus (NIDDM) and 105 healthy control subjects. Distribution of the ACE genotype did not differ between healthy control subjects and diabetic patients without complications. However, the frequency of the D allele was significantly higher in the diabetic subjects with nephropathy than in those without (0.32 in normoalbuminuric patients vs 0.44 in albuminuria patients with albuminuria) (χ2=7.7; p=0.006). There was no significant association between ACE genotype and retinopathy. These observations thus demonstrate a significant association of the ACE gene polymorphism with nephropathy, but not with retinopathy, in Japanese patients with NIDDM.

    Notes: Summary We determined the population-based prevalence of diabetes mellitus in members of the Japanese community, Hisayama aged 40–79 years old by a 75-g oral glucose tolerance test. The basic population used to calculate diabetic prevalence was 1,077 men (72.8% of the whole population in the same age range) and 1,413 women (80.8%) including ten diabetic patients on insulin therapy. In addition, we compared the prevalence of history of diabetes which was acquired by interview or questionnaire, between participants and non-participants in the 75-g oral glucose tolerance test, but they were not statistically different. The age-adjusted prevalence of diabetes to world population was 12.7% for men and 8.4% for women, and that of impaired glucose tolerance was 19.6% for men and 18.4% for women. These figures were much higher than those previously reported from several Japanese communities. The results obtained from the present study could reveal true prevalence of diabetes among the Japanese population. In addition, the reasons for the increasing prevalence of diabetes among the recent Japanese population are also discussed.

    Notes: Summary While non-enzymatic glycation of long-lived tissue proteins such as collagen has been implicated in chronic complications of diabetes mellitus, its role in the aetiology of diabetic macroangiopathy has not been elucidated. To test the hypothesis that glycation of collagen abolishes the inhibitory effect of native collagen on the proliferation of human smooth muscle cells, we obtained smooth muscle cells from human gastric arteries and cultured them on dishes coated with glycated or non-glycated collagen. The proliferation of human smooth muscle cells in the presence of 10 % fetal calf serum or platelet derived growth factor-BB (10 ng/ml) was inhibited by type 1 collagen coated on the dishes. Glycation of collagen with glucose 6-phosphate for 7 days abolished the growth-inhibitory effect of native collagen. Succinylation of collagen, which like glycation blocked the lysyl residues in collagen, also abolished the growth-inhibitory effect. Adhesion of human smooth muscle cells to collagen-coated dishes was not affected by glycation of collagen. Addition of glycated albumin to the medium did not affect the growth of human smooth muscle cells on plastic dishes. The inhibition of human smooth muscle cell proliferation by collagen was not reversed by the glycation of collagen in the presence of aminoguanidine. Results suggest that early glycation abolishes the inhibitory effect of collagen on human smooth muscle cell proliferation and may thus participate in the progression of macroangiopathy in diabetes.

    Notes: Abstract We evaluated a 72-year-old woman who was experiencing dysphagia. Esophageal leiomyosarcoma was diagnosed by barium meal study, upper gastrointestinal endoscopy, endoscopic ultrasonography (EUS), by computed tomography (CT). A barium meal study and esophagoscopy performed 3 months before the diagnosis of esophageal leiomyosarcoma showed no abnormalities. Therefore, the tumor appeared to have grown rapidly during the 3-month period.

    Notes: Abstract We report an extremely rare case of primary ileal plasmacytoma accompanied by mixed low- and high-grade B-cell lymphoma of mucosa-associated lymphoid tissue (MALT) type. The radiographic and macroscopic features of the tumor were characterized by two constricting lesions in the ileum. Histologic examination of the resected specimen showed that one constrictive lesion was plasmacytoma and the other MALT lymphoma was low and high grade. The plasmacytoma seemed to have differentiated from the MALT lymphoma.

    Notes: Summary The relationship of the vascular changes to the cerebral lesions has been studied using serial sections of the brains from five cases of the strokeprone spontaneously hypertensive rats. Infraction was observed in a form of microinfarct related to single or plural occluded arterioles in the brain and subarachnoid space. Though most arterioles with fibrinoid necrosis of the wall were occluded with thrombus, infarct, which was obviously related to the occluded arterioles, was verified only in a few occasions. It was proved that infarction did not develop in all the areas irrigated by the occluded arterioles, and the regional circulation was assumed to have been maintained by the collateral circulation. There was rarefaction of the neuropil with preservation of the neurons in the cortex around the vascular changes, such as fibrinoid necrosis of the wall. Widespread rarefaction and cyst formation were observed in the subjacent white matter, which were more marked in the vicinity of the vascular changes in the cortex. These histological changes were interpreted to be the tissue degeneration secondary to edema.

    Notes: Abstract Objectives: Lysophosphatidylcholine (LPC) in low-density lipoprotein (LDL) comes into notice as an important atherogenic substance. Methods: Since the effect of probucol, an antioxidative lipid-lowering drug, on LPC molecular species has not been elucidated, two LPC molecular species, stearoyl LPC (SLPC) and palmitoyl LPC (PLPC), were measured in LDL using high-pressure liquid chromatography. LDL was obtained from 11 hyperlipidemic patients, including 9 diabetic patients, in comparison with 11 age- and gender-matched controls. Results and conclusion: Hyperlipidemic patients showed nearly twofold higher levels of SLPC and PLPC per gram of LDL protein than those of controls. All hyperlipidemic patients were treated with oral administration of 500 mg/day of probucol for 3 months. Both LPCs in LDL were significantly reduced to control levels and were increased again up to the pretreatment levels 4 weeks after cessation of the treatment. Therefore, probucol has a potent effect in reducing LPC and may contribute to decreasing the atherogenicity of LDL.
