A possibility that interferon may potentiate the cytotoxic effects of anticancer drugs or 60Co gamma ray on human neoplastic cells was studied by in vitro and vivo experimental procedures. The used were HeLa (uterine cervical cancer) WI-38 CT-1 (embryonic lung fibroblasts transformed culture ray) cells. As normal cells, used. Interferon a preparation β-type produced fibroblasts. cytotoxicity determined colony formation for experiments tumor growth animal experiments. Of 17 drugs, six namely,...

Phase I clinical studies of 7432‐S, a new oral cephalosporin, including randomized placebo‐controlled trial were conducted with 40 healthy volunteers, in single‐dose studies, 7432‐S was orally administered at doses 25, 50, 100, and 200 mg. The mean plasma levels peaked 2.1 to 3.0 hours reached 1.9, 3.6, 5.6, 11.6 μg/ml, respectively. Linear correlation observed between AUC values given. half‐lives the 0.88 2.26 1.53 ± 0.33 hours. urinary recoveries 67.5 75.2% dose within 24 partially...

Analytic approaches of thermal stress in plastic-encapslated ICs reliability have been studied using a simple, 2-dimensional model the cross section by finite-element method. To test validity model, actual within silicon chip was measured piezoresistive devices. The calculated agreed with experimental values. distributions were changed lead-frame properties. Package cracking, and delamination between molding plastic qualitatively explained. We estimated effect properties on quantitatively....

We studied the effect of lithium addition to neuroleptic treatment in chronic schizophrenia, for which contradictory results have been produced previous studies. Twenty‐one schizophrenic inpatients received a study with randomized, double‐blind, placebo‐controlled, cross‐over design consisting 8 weeks each capsules and identical placebo capsules. The total Brief Psychiatric Rating Scale (BPRS) scores at week were improved significantly compared those treatment. Of BPRS subscales, however,...

Study background: The objective of study is a survey to report the prevalence burning mouth syndrome (BMS) and evaluated co-morbidities associated BMS. Subjects Methods: A total 393 patients (54 males 339 females; mean age 67 years; range 27-102) were selected for this study. We carried out initial screening blood tests these patients. Furthermore, we examined if there previous and/or present systemic diseases regularly taken medication by medical interview. Results: Female over 50 years old...

Dose volume histogram (DVH) is one of the methods for evaluating feasibility radiotherapy plans. It difficult to thoroughly comprehend an evaluation each plan at a glance and give concise presentation case conference. In this study, we provide useful program that will fulfill such purpose on clinical setting. We have revised our protocols planning, developed using Visual Basic 2010, which could facilitate DVH, used it checking plans Since DVH analysis shows result in simple way, as “OK...
