Evaluation of pericardial effusion was attempted with computed tomography in 11 patients. The volume and distribution of pericardial fluid were assessed with satisfactory resolution and the nature of the fluid was estimated by the difference in x-ray transparency (CT numbers). The volume of pericardial fluid calculated by tomographic methods ranged from 25(More)
AIM Diabetic xerostomia is a typical syndrome in diabetic complication. We have reported that salivatin (salivary peptide P-C) derived from human saliva potentiates glucose-stimulated insulin release and inhibits arginine-stimulated glucagon release. The present study is aimed to gain further evidence on the physiological role by investigating the diabetic(More)
Through the examination of 171 electrocardiograms (ECG) of 101 patients with primary pulmonary hypertension (PPH), the following conclusions were obtained. Arrhythmias were found in 27 (26.7%) of the 101 patients. Among the surviving cases, arrhythmias were found in 8 (17.8%) out of 45 patients, but among the decreased cases, the figure was higher, 19(More)
The characteristics of 59 chest roentgenograms of patients with primary pulmonary hypertension were investigated and compared with roentgenograms of 100 healthy control subjects. The relationship with pulmonary hemodynamics was also examined. In primary pulmonary hypertension, there was remarkable protrusion of the main pulmonary artery; the DPA (T/2) and(More)
Human saliva contains a proline-rich polypeptide, salivary peptide P-C, which potentiates insulin release and reduces glucagon release from perfused rat pancreas to decrease blood glucose level. To elucidate the process of secretion into humoral fluid of this peptide morphologically, we investigated ultrastructural localization of P-C in human submandibular(More)
A 58-year-old man was diagnosed as having advanced gallbladder cancer (T4, P0, H0, N0, stage IVa) with direct invasion to the liver, transverse colon and duodenum. Therefore, extended cholecystectomy and bile duct resection with a partial resection of the transverse colon and the duodenum were performed in March 1992. Histopathological examination revealed(More)
