BACKGROUND Disialosyl globopentaosylceramide (DSGb5) is a ganglioside originally isolated from renal cell carcinoma (RCC) tissue that has been associated with RCC metastasis. However, in prostate cancer, the expression of DSGb5 has not yet been fully assessed. In this study, we investigated DSGb5 expression in prostate tissues and the relationship between(More)
In renal cell carcinoma (RCC), the presence of higher gangliosides correlates with systematic metastasis. Disialosyl globopentaosylceramide (DSGb5) was identified previously as one of the major gangliosides from RCC tissues. Siglec-7 (sialic acid-binding Ig-like lectin-7), expressed on natural killer (NK) cells as an inhibitory receptor, has a striking(More)
In our previous study, monoclonal antibody RM2, established toward the glycosyl epitope, reflected grade of malignancy of prostate cancer cells whereas RM2 reactivity to benign glands was negative or weak. RM2 reactivity was also detected in stroma, suggesting the glycoprotein RM2 recognizes could be released into the bloodstream. Then, we explored RM2(More)
An expression system for mono- and bivalent single-chain Fv fragments (scFv) of a human antibody against D antigen in the Rh blood group system was established in Escherichia coli. The cDNA encoding the Fv fragment of the anti-D monoclonal antibody D10 was cloned using the polymerase chain reaction and expressed in E.coli by fusing with a peptide tag link(More)
The therapeutic effects of a new antiulcer drug, a p-hydroxyphenyl-propionic ester of tranexamic acid (cetraxate, CET) hydrochloride, were investigated in 234 patients with gastric ulcer by double blind controlled study using trans-3,7-dimethyl-2,6-octadienyl-5,9,13-trimethyltetradeca-4,8,12-trienoate (gefarnate) as the standard drug in 18 medical(More)
99mTc pertechnetate imaging of the stomach was carried out in a case of 63-year-old man 15 min after amogastrin. A coldness on the scintigram led to an exploratory laparotomy, and a carcinoma in situ was found and operated.-gastric Scintigraphy; amogastrin; diagnosis of early gastric cancer This paper is to report clinical usefulness of amogastrin-99mTc(More)
Mucosal secretin content of the duodenum was measured using bioptic specimen in healthy controls and patients of peptic ulcer. Immunoreactive secretin in the duodenal mucosa was found greater in healthy controls (7.73 +/- 2.71 ng/mg dry wt., mean +/- S.D.) than in gastric ulcer patients (5.76 +/- 3.51 ng/mg dry wt.) and duodenal ulcer patients (5.54 +/-(More)
Eight patients with esophageal cancer were treated by a new treatment schedule consisting of low dose irradiation, crescendo cisplatin and bleomycin polyacrylate pasta. As monitored endoscopically, therapeutic responses were satisfactory: seven out of 8 patients have survived for a range of 3 to 20 months and still active at work or cancer-free. However,(More)
