A total of 979 patients with gastric cancer were admitted to the authors' clinic for hospitalization during the period from 1956 to 1971. Of these 109 patients were subjected from recurrent gastric cancer and 58 of these (53.2 per cent) were subjected to surgical operation. Of the operations performed for the treatment of recurrent gastric cancer, anastomosis of the intestines for the formation of a by-pass to cope with disturbance passage was the most frequent. This was con ducted on 18 patients (31.0 per cent) and plain laparotomy on 15 patients (25.8 per cent) and jejunostomy for the supply of nutrition on 6 patients. Only 4 patients were subjected to gastrectomy, including total excision of the remaining part of the stomach (in one patient total gastrectomy). Prognosis was not good in these patients, only one surviving for more than 2 years. Discussion on these results led conclusively to the importance of the first operation for successful gastric carcinectomy and the necessity of some auxiliary methods in addition to the surgical operation for treatment. The results of treatment obtained by the auhors for the past l 6 years are mentioned in the present report.
Physiological reactions of 29 wintering members in the frigid climate were observed at the Syowa Station and during the South Pole Traverse. Mean atmospheric temperature at the station was -10°C (+9.5℃ to -32.4℃), mean wind velocity was 6.4 m/s and mean relative humidity was 62%. About 30% and 13% of the day were spent in various outdoor activities by the traverse members and the base members, respectively. Energy balance was positive at the station but negative during the traverse. Therefore, the body weight tended to increase at the station. A significant positive correlation was found in both groups between the changes of the skinfold thickness of the abdominal wall and the body weight. Basal metabolism of the base members showed a seasonal variation. The value increased when the outside temperature lowered and decreased as the outside temperature rose. This is considered to be the result of acclimatization to the cold. Blood pressure tended to fall in the winter. Vital capacity showed a decrease due to physical fatigue. Hemoconcentration was observed after the Autumn Traverse. During the South Pole Traverse, erythrocytosis caused by high altitude, unexplained leukopenia and relative lymphocytosis were recognized.
We performed 99mTc pertechnetate brain scanning 27 Limes on 15 infantile subdural hematoma cases. These scannings gave positive results in 74%, doubtfully positive in 18%, and negative in 8%. In selected cases, scans were obtained after appropriate delay periods as well as at conventional times. In some cases, scans which were initially interpreted as borderline or negative were read as definitely abnormal on delayed studies. The radioactivity in the serial blood and subdural samples was measured in a well-type scintillation counter. This study clarified a part of the biodynamic mechanism underlying the successful detection of infantile subdural hematomas by external scintillation scanning. Our result shows that both the subdural fluid and subdural neomembrane influence the production of a positive scan, but whether the isotope is localized predominantly in the membrane or in the subdural fluid depends upon the kind of radioisotope used, hematoma age, the nature of the subdural fluid and the time interval between the injection of radioisotope and scanning. The total volume of the subdural space is assessable more exactly by the isotope dilution method than by the simple 2 dimensional gamma ray image of the subdural hematoma. This tells more of the clinical value because of its importance in planning the therapy.
This paper describes electron microscopic observations on early changes in the endocardium, especially of the endothelial cells, and the basement membrane by means of the activity of virus particles found incidentally in the cardiac valve of apparently normal chickens injected with Streptococcus faecalis, during a study on experimental bacterial endocarditis. Aggregation of virus particles was found in the focal edema around the basement membrane of the subendothelial region. Various alterations in the basement membrane were found from the subendothelial focal edema, and Tanged from fibrillation, lamellation, fragmentation, segmentation, and disruption to disappearance. Most of them found in the auricular surface of the mitral valve were more intense than in the ventricular surface. Only the subendothelial fibrillogenesis in relation to the basement membrane was more marked in the ventricular surface. The degenerative changes of the endothelial cells such as shrinkage, collapse, apparent necrosis, and desquamation were seen more frequently in the auricular surface. These endothelial cellular changes appeared to depend on the reaction of the basement membrane for the subendothelial focal ellema considered to be the initial lesion in the vegetative endocarditis.
This investigation was carried out to analyze the lateral force distribution of the unilateral extension saddle partial denture, particularly the relationship between the denture design and the residual ridge form. For this purpose, the previously reported materials and experimental equipments were used. Conclusions were as follows: (i) The lateral load distribution was highly affected by the condition of residual ridge and the denture design. (ii) When the condition of residual ridge tends to be clinically poor, with excess bone loss, cross arch-designed indirect retainer highly withstands lateral load distributions.
