    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.

    Notes: Summary Fourteen normotensive patients with liver disease (6 with cirrhosis and 8 with chronic hepatitis) and 7 healthy volunteers were given a single oral dose of nilvadipine 2 mg. In addition, nilvadipine 4 mg was administered orally twice daily for several months to 6 hypertensive patients with mild liver dysfunction and 18 hypertensives with normal liver function. A significant increase in plasma nilvadipine was found in the patients with cirrhosis as compared both to the normal and chronic hepatitis subjects; the time to peak concentration was similar among the three groups. The peak plasma nilvadipine concentration was closely correlated both with the serum albumin level and the retention of indocyanine green. Changes in blood pressure, pulse rate and various vasoactive hormones following a single oral dose of nilvadipine did not differ between the groups. Thus, an increase in plasma nilvadipine relative to the level in normal subjects was demonstrated in patients with cirrhosis following a single oral dose, as well as in patients with slight liver dysfunction following long-term oral administration.

    Notes: Abstract Clinical and endoscopic manifestations of 18 gastric inflammatory fibroid polyps (IFP) in 16 patients who underwent endoscopic or surgical removal were retrospectively analyzed. All of the lesions were located within the pyloric antrum, and the sizes varied from 0.8 to 7.0 cm. On endoscopy, six polyps which measured 1.0 cm or less uniformly seemed to be sessile or intramural tumors, whereas four of the nine polyps between 1.1 and 2.0 cm in size were additionally accompanied by a central depression. The remaining three, which measured more than 2.0 cm, showed characteristic polypoid growth with ulcerations. Three polyps more than 1.0 cm in size occasionally prolapsed into the duodenal bulb. Three patients with these prolapsing polyps and two with polyps accompanied by ulcerations experienced abdominal pain, nausea, or severe anemia. Two polyps (11%) were precisely diagnosed as IFP by means of conventional forceps biopsy. Histological examinations revealed that all of the polyps proliferated within the submucosa. Therefore, this type of polyp may be subject to endoscopic removal to enable a precise diagnosis and treatment.

    Notes: Abstract A total of 263 gastric hyperplastic polyps, which had been removed endoscopically from 202 patients, were clinicopathologically analyzed. Among these polyps, there were nine polyps with neoplastic components (3.4%), corresponding to adenoma in five lesions and mucosal adenocarcinoma in four lesions. Comparing the neoplastic transformed polyps with the pure hyperplastic polyps, there was no significant difference according to age, gender, location, gross appearance, or size. However, the transformed polyps which were located in the lower third of the stomach were larger in size (mean, 20.8 mm) and were more likely to be found among older patients (mean, 75.8 years) than were the pure hyperplastic polyps (mean size and age: 14.5 mm and 61.8 years). These results may indicate the possibility of a different carcinogenesis belonging to gastric hyperplastic polyps by location, and this finding seems to be significant in the application of endoscopic polypectomy.
