The exact measurement of femoral head cover is essential for an assessment of reduction of congenital dislocation of the hip. We have compared standard anteroposterior radiographs with computerised tomograms and thereby classified the shape of the acetabular roof into four types. We found that the CE angle of Wiberg is a more reliable measure of head cover(More)
BACKGROUND AND PURPOSE 5-Chloro-2,4-dihydroxypyridine (Gimeracil) is a component of an oral fluoropyrimidine derivative S-1. Gimeracil is originally added to S-1 to yield prolonged 5-FU concentrations in tumor tissues by inhibiting dihydropyrimidine dehydrogenase, which degrades 5-FU. We found that Gimeracil by itself had the radiosensitizing effect. (More)
BACKGROUND To investigate and analyze changes in irradiated salivary gland function of patients with head and neck tumors treated with radiotherapy. METHODS Thirty-seven patients with head and neck tumors, who received 40-70 Gy of irradiation to all major salivary glands, were analyzed. The weights of saliva secreted for 10 minutes at rest, and for 5(More)
Hyperfractionated accelerated radiotherapy without a split (AF) has been performed to improve the local control probability of early glottic carcinomas since 1990 in the authors’ institution. Here, they report their experience treating early glottic cancer patients with AF in a single institution who have a long follow-up period. 131 T1 N0 M0 glottic(More)
We report our experiences of four cases with meningeal hemangiopericytoma treated with surgery and postoperative radiotherapy and survey the literature to elucidate the efficacy of radiotherapy. Patients were treated with surgical resection and 46-52 Gy postoperative radiotherapy. Three patients had local control for 30, 54 and 138 months, respectively and(More)
DNA-dependent protein kinase (DNA-PK) is thought to play a pivotal role in DNA double-strand break repair. We recently demonstrated the association of DNA-PK activity in peripheral blood lymphocytes (PBL) with the incidence of chromosomal aberrations and the risk of cancer. In this study, we applied cDNA array technology to find the expression of genes(More)
Recent advances of ultrasound imaging have made possible to depict various diseases and conditions of the pancreas. Color/power Doppler ultrasonography, endoscopic ultrasonography, and intraductal ultrasonography are feasible to show vascular abnormalities, differentiate the solid and cystic tumors, decide tumor extent, and help to perform interventional(More)
Hip arthrography was performed in 19 patients in the initial stage of Perthes' disease. Sphericity and subluxation were measured and it was found that subluxation was independent of the femoral head deformity. We therefore tried to identify the cause of early subluxation: in seven patients a swollen ligamentum teres was thought to be responsible, and was(More)
DNA double-strand break (DSB) is one of the most deleterious lesions induced by DNA damaging agents. DSB repair pathway is implicated in maintaining genomic integrity via suppression of genetic instability and neoplastic transformation. DNA-dependent protein kinase (DNA-PK) has a pivotal role in DNA DSB repair. The Nijmegen breakage syndrome protein (NBS1),(More)
The DNA double-strand breaks (DSBs) repair pathway has been implicated in maintaining genomic integrity via suppression of chromosomal rearrangements. DNA-dependent protein kinase (DNA-PK) has an important role with DNA DSBs repair. In this study, 93 of untreated cancer patients and 41 of cancer-free healthy volunteers were enrolled. Peripheral blood was(More)
