The possible preventive effect of cilostazol, a novel anti-platelet drug, on restenosis after successful percutaneous transluminal coronary angioplasty (PTCA) was examined. One hundred and two consecutive patients, who underwent successful PTCA, were followed for 3 to 6 months. To prevent restenosis, 46 patients (60 PTCA sites) were treated with cilostazol(More)
A total of 1,845 cases of gastric cancer have been resected in our hospital during the past 18 years. Of these, 764 cases (41.5%) were early gastric cancer. The rate of lymph node metastasis was 2% in early mucosal cancer and 19.4% in early submucosal cancer (p < 0.001). In the cases of early mucosal cancer, the rate of lymph node metastasis was 0.9% for(More)
It has been hypothesized that intracellular magnesium deficiency is a pathogenetic factor in acute myocardial infarction. This study examined the time course of changes in the erythrocyte magnesium concentration and the correlation between the erythrocyte magnesium concentration and the severity of acute myocardial infarction in 49 consecutive patients with(More)
A 61-year-old woman was admitted to our hospital with abnormal findings of abdominal computed tomography. Whereas she had neither fever nor abdominal pain, a cholecystitis was suspected. Ultrasonography showed a mass in the gallbladder with several stones, and an unclear border between the gallbladder and liver. Computed tomography showed a large-mass in(More)
A 19-year-old woman with long-standing mixed connective tissue disease was admitted for dizziness. We examined cerebral blood flow quantitation using 99mTc-hexamethylpropyleneamine oxime (HMPAO) and single photon emission computed tomography (SPECT) at rest and after cold pressor test. Mean cerebral blood flow reduced remarkably when she complained(More)
OBJECTIVE We investigated the frequency of cytomegalovirus (CMV) infection during immunosuppressive therapy in collagen vascular disease by using CMV antigenemia assay. METHODS CMV antigenemia in fifteen patients with collagen vascular disease were analyzed before and one month after immunosuppressive therapy with more than 30 mg/day of prednisolone. (More)
Computed tomographic images of brains from 26 individuals (10 males and 16 females) with Down syndrome were analysed for roentogenographic measurement. Their ages ranged from 14 to 47 years, the average being 28 years. The results showed that their Sylvian fissure ratio was larger in the aged group. A high incidence of calcification in basal ganglia,(More)
We present a 70-year-old man with lymphoma who presented with a right eye movement disorder. CT examinations showed 'ground-glass' appearance extending around the right sphenoid sinus which suggested fibrous dysplasia. However, biopsy from the mass histologically proved it to be diffusing large B-cell lymphoma and positron emission tomography examinations(More)
