Nine healthy men (22-45 yr) completed 100 repetitive maximal isometric contractions of the ankle plantar flexor muscles in two knee positions of full extension (K0) and flexion at 90 degrees (K90), positions that varied the contribution of the gastrocnemii. Electromyographic activity was recorded from the medial and lateral gastrocnemii and soleus muscles(More)
BACKGROUND Risks of increasing mortality and disability in aortic arch operations using the selective cerebral perfusion method for nondissecting aneurysm have not yet been determined. A multicenter, retrospective study was employed. METHODS The subjects were 143 patients who were admitted to one of the nine cardiovascular centers between January 1988 and(More)
BACKGROUND Little is known about the risks of mortality and morbidity after descending thoracic aortic aneurysm repair using left heart bypass and temporary arterioarterial bypass. METHODS A multicenter, retrospective study was performed on 120 patients who were admitted to one of nine cardiovascular centers between January 1988 and December 1993 and(More)
Duplication of the alimentary tract is a rare congenital malformation that occurs most often in the abdominal region, whereas esophageal duplication cyst develops typically in the thoracic region but occasionally in the neck and abdominal regions. Esophageal duplication cyst is usually diagnosed in early childhood because of symptoms related to bleeding,(More)
Clinical usefulness of 67Ga-citrate scintigraphy for the diagnosis of colorectal carcinoma was reappraised at the standpoint of clinicopathological diagnosis. Fifty-eight patients with colonic carcinoma were subjected to this study. They underwent 67Ga scintigraphy before surgery. Colorectal carcinomas were detected in 38 patients, 65.5% by this procedure.(More)
The purpose of this paper is to evaluate the efficacy and limitation of the non-quantitative analysis of renography using 99mTc-DTPA, and to determine the clinical indication of the quantitative analysis of the study. We evaluated the clinical records of the patients and the findings of dynamic imagings and renograms. The non-quantitative analysis of the(More)
Portal vein thrombosis (PVT) is a rare but serious postoperative complication of pancreaticoduodenectomy (PD). We reported a case of late-onset postoperative PVT with hemorrhage from the common hepatic artery (CHA) in a 73-year-old man who underwent pylorus-preserving pancreaticoduodenectomy (PPPD) for duodenum papilla cancer, followed by reconstruction(More)
Mixed Müllerian Tumor (M.M.T.) is a rare malignant neoplasm usually arising from uterine body in postmenoposal woman, and imaging diagnosis for the tumor has not been established. A 45-year-old female with pathologically confirmed M.M.T. was evaluated by 67Ga-citrate scintigraphy and CT on the basis of imaging diagnosis. 67Ga-citrate scintigraphy detected(More)
Transcatheter arterial infusion chemotherapy is one of the most useful therapeutic procedures for gynecologic malignancies. Recently, several reports have been published about Angiotensin II-induced hypertension chemotherapy and the efficacy of the method, but there have been no reports to evaluate an application for gynecologic malignancies. We evaluate(More)
Twenty-seven cases of colorectal carcinoma were evaluated by 67Ga-scintigraphy on the basis of clinicopathologic viewpoint. On each cases, 67Ga-scintigraphy was performed just before the operation, and resected specimen was also examined after the operation. In 17 cases (63%), the lesions were demonstrated on preoperative 67Ga-scintigraphy, on the other(More)
