Seventy five cases of urogenital malignant tumors were reviewed in regard to the survival, therapy and peripheral lymphocyte counts. Cellular immunity was also investigated in 15 cases of them by assessing their cutaneous delayed hypersensitivity responses to dinitrochlorobenzene (DNCB), compared with controls. I. The incidence of lymphopenia in the urogenital malignant tumors (20. 6%) was higher than that in the control group(10.0%). Most cases with lymphopenia showed poor survival, and data suggested that peripheral lymphocyte count was a useful parameter to estimate the prognosis of the urogenital malignant tumors. 2. Surgical treatments caused a temporal decrease of circulating lymphocyte counts by 27.6% which recovered to normal value within 4 weeks, and high dosage radiation therapy brought about persistent and higher degree of decrease of peripheral lymphocyte by 47.9% which persisted for up 1-2 years. 3. Cancer patients had a lower incidence of positive reaction (73.3% vs. 93.4% in controls) in investigation of cellular immune responses using quantitative DNCB contact sensitization. There may be a significant relationship between tumor stage and reactivity to DNCB in bladder cancers.

PURPOSE: To define the histologic correlation of the ultrsonic gastric wall layers of resected human gastric specimens. MATERIALS AND METHODS: UItrasound images of the gastric wall by using 5 or 7.5 MHz linear transducer were compared with the corresponding histologic sections of 30 surgically resected human gastric specimens. RESULTS: Five layers seen from within on ultrasound images of the normal gastric wall corresponded to (1) the acoustic interface between fluid bathing the surgical specimen and the mucosal surface and a portion of the superficial mucosa, (2) the deep mucosa including the muscularis mucosae and most of the superficial mucosa, (3) the submucosa plus the acoustic interface between the submucosa and the muscularis propria, (4) the muscularis propria minus the acoustic interface between the submucosa and the muscularis propria, and (5) the serosa and the subserosal tissue plus the acoustic interface between the serosa and the fluid bathing the surgical specimen. Ultrasonic findings in gastric carcinomas corresponded to their histopathologic findings. CONCLUSION: Histologic correlation of the ultrasonic gastric wall layers will provide us with a very useful and objective basis of gastric ultrasonography.

Fractures of the femoral neck in children are rare and usually the result of severe trauma. The femoral necks in children, in contrast to those of adults, have many anatomic and physiologic differences. Among the late complications encountered are avascular necrosis, coxa vara, premature closure of the proximal capital femoral epiphysis and nonunion. In spite of careful management, significant complication rate often results. Nine cases of fractures of the femoral neck in children which were treated at Yeungnam University Hospital from June 1984 to August 1987 were reviewed. The results obtained are as follows: 1. The main causes of fractures were traffic accidents (5 cases). 2. Among 9 patients, 6 were girls and 3 were boys. 3. According to the classification of Delbet and Colonna, the transcervical fracture (6 cases) was the commonest type. 4. 4 cases were treated by closed reduction and internal fixation, 3 cases were treated by open reduction and internal fixation. 2 cases were treated by skin traction and cast. 5. The results were analyzed according to Ratliff's assessment. 6 cases showed good results, and 3 cases showed poor results. 6. Early diagnosis and good fixation method seemed to be vital to prognosis.
