A case of metastatic sarcomatoid renal cell carcinoma to the mandible treated with Sorafenib is reported. A 76-year-old man consulted us for hyposthesia of the right lower lip. Panorama X-ray film showed a ra-diolucent lesion in the right mandibular body. A diagnosis of metastatic tumor to the mandible from the left kidney was made after evaluation by computed tomography and positron emission tomography, which also revealed multiple bone metastases. After radiotherapy for mandibular and thoracic lesions, nephrectomy was performed. Histological diagnosis was sarcomatoid renal cell carcinoma. Interferon therapy was performed but was not effective;therefore, a molecular targeted drug, Sorafenib, was administered. Sorafenib effectively inhibited the growth of oral and other metastatic lesions for 10 months. Quality of life was relatively well maintained with tolerable adverse effects. The patient survived for as long as 2 years after appearance of the first symptom.

Purpose: To evaluate the usefulness of 3D-model, factors of complications and postoperative function and esthetics on mandibular reconstruction with vascularized fibular osteocutaneous flaps。Methods" The subjects were 43 patients (27 males, 16 females; mean age 57.5 years; range 14 to 77 years), in whom most of the primary diseases were malignant tumors, from July 1987 to November 2007。The 3D-model of the mandible and fibula were made preoperatively from 3D CT scans in order to perform mandibulectomy and osteotomies of the fibula accurately and swiftly。Guide templates were also prefabricated from the model。The types of the defect of the mandible and the soft tissue, the length of mandibular defects,the number of osteotomies of the harvested fibula, and the time of shaping harvested fibula were evaluated。Results- The number of osteotomies ranged from 0 to 4。The model surgery applied group was able to shorten the time of shaping harvested fibula significantly compared with non-applied group。Complications such as necrosis of grafted flaps and delayed union of grafted fibula correlated not with the number of osteotomies, but with the length of the mandibular defect。Postoperative functions such as swallowing, speaking and esthetic satisfaction did not correlate with the type of the defect of the mandible or soft tissue。Nonetheless, the size of the intraoral flap demonstrated a negative correlation with esthetic satisfaction。

Purpose: To clarify the effectiveness of 3-D delivery animation software for the mother’s and husband’s satisfaction with delivery. Subjects and Method: We independently developed a software application used to display the pelvic region and explain the labor process. The study involved a collaboration with hospital staff who recruited 18 primiparous and 18 multiparous mothers who were hospitalized for delivery at Facility A. The midwife explained the process of delivery using the “Delivery Animation Software”. A self-administered, anonymous questionnaire was distributed and analyzed separately for primiparous and multiparous mothers and their husbands. Results: 1) For both primiparous and multiparous couples, both mothers and their husbands gained a significantly higher level of understanding after delivery than during pregnancy. 2) The Self-Evaluation Scale for Experience of Delivery results were as follows: “I did my best for the baby even if it was painful” was selected more often for “birth coping skills”;“reliable medical staff” was selected more often for “physiological birth process”;“the birth progressed as I expected” was selected frequently by primiparous mothers;and “the birth progressed smoothly” was selected often by multiparous mothers. 3) In terms of husbands’ satisfaction with the delivery, “I was satisfied with the delivery”, “I was given an easy-to-understand explanation”, and “They explained the process to me” was selected of primiparous and multiparous fathers. 4) All primiparous and multiparous mothers positively evaluated whether the delivery animation was helpful in understanding the process of delivery. Conclusion: The delivery animation was effective in improving the understanding and satisfaction of both the mothers and their husbands.

Preparation of large mesoporous tin dioxide (lm-SnO_2) under various conditions was attempted by utilizing a self-assembly of a triblock copolymer,P123:(EO)_(20)(PO)_(70)(EO)_(20) or F127:(EO)_(106)(PO)_(70)(EO)_(106)(EO:ethylene oxide and PO: propylene oxide).The sensor fabricated from calcined lm-SnO_2 powder,which had been prepared by using P123 as a template,Na_2SnO_3 as a tin source,and TEOS as an additive ([TEOS]/[Na_2SnO_3]=0.5 in the precursor solution),showed the largest response to 1×10^(-3) hydrogen at 350℃among the sensors *** existence of two kinds of SnO_2 particles with different sizes (ca.100 nm and several nm in diameter) may be important to improve the hydrogen sensing properties drastically.

Anion exchange resins （AERs） with different properties were evaluated for their ability to remove dissolved organic matter （DOM） and bromide, and to reduce disinfection by-product （DBP） formation potentials of water collected from a eutrophic surface water source in Japan. DOM and bromide were simultaneously removed by all selected AERs in batch adsorption experiments. A polyacrylic magnetic ion exchange resin （MIEX） showed faster dissolved organic carbon （DOC） removal than other AERs because it had the smallest resin bead size. Aromatic DOM fractions with molecular weight larger than 1600 Da and fluorescent organic fractions of fulvic acid- and humic acid-like compounds were efficiently removed by all AERs. Polystyrene AERs were more effective in bromide removal than polyacrylic AERs. This result implied that the properties of AERs, i.e. material and resin size, influenced not only DOM removal but also bromide removal efficiency, MIEX showed significant chlorinated DBP removal because it had the highest DOC removal within 30 rain, whereas polystyrene AERs efficiently removed brominated DBPs, especially brominated trihalomethane species. The results suggested that, depending on source water DOM and bromide concentration, selecting a suitable AER is a key factor in effective control of chlorinated and brominated DBPs in drinking water.

Arsenic is a well-known human bladder and liver carcinogen, but its exact mechanism of carcinogenicity is not fully understood. Dimethylarsinic acid（DMAV） is a major urinary metabolite of sodium arsenite（i As~Ⅲ） and induces urinary bladder cancers in rats. DMAVand i As~Ⅲare negative in in vitro mutagenicity tests. However, their in vivo mutagenicities have not been determined. The purpose of present study is to evaluate the in vivo mutagenicities of DMAVand i As~Ⅲin rat urinary bladder epithelium and liver using gpt delta F344 ***-week old male gpt delta F344 rats were randomized into 3 groups and administered 0,92 mg/L DMAV, or 87 mg/L i As~Ⅲ（each 50 mg/L As） for 13 weeks in the drinking water. In the mutation assay, point mutations are detected in the gpt gene by 6-thioguanine selection（gpt assay） and deletion mutations are identified in the red/gam genes by Spi-selection（Spi-assay）. Results of the gpt and Spi-assays showed that DMAVand i As~Ⅲhad no effects on the mutant frequencies or mutation spectrum in urinary bladder epithelium or liver. These findings indicate that DMAVand i As~Ⅲare not mutagenic in urinary bladder epithelium or liver in rats.
