The efficiency of clove oil, MS-222, and 2-phenoxyethanol was evaluated as anesthetics in juvenile Scomber japonicus . Stage A5 of anesthesia was assumed to be sufficient for conducting routine aquaculture procedures in less than 3 min, with recovery (stage R5) in less than 5 min. The lowest effective doses of the three anesthetics were 50 mg L-1 clove oil (anesthetic time of 71.3 s and recovery time of 167.0 s), 100 mg L-1 MS-222 (anesthetic time of 70.7 s and recovery time of 115.7 s), and 400 mg L-1 2-phenoxyethanol (anesthetic time of 86.7 s and recovery time of 95.0 s). Anesthetic times decreased with increasing doses for all three anesthetic agents, and fish anesthetized with clove oil exhibited the longest recovery times. After 30 min, the highest plasma cortisol and lactate levels were detected with the use of clove oil, whereas the lowest values were observed with 2-phenoxyethanol. In addition, high glucose levels were maintained during recovery with clove oil, but the treatments did not significantly differ. The most effective of the three anesthetic agents was 2-phenoxyethanol, although all were considered acceptable for use in cultures of juvenile Scomber japonicus

Purpose: Gemcitabine and 5-fluorouracil (5-FU) are twocompounds with reproducible activity against advancedpancreatic carcinomas. To evaluate the activity and feasibilityof this combination chemotherapy, a multi-institutionalphase II study was performed.Materials and Methods: Twenty patients (maleခfemale15ခ5, median age: 60.5 years), with histologically verifiedlocally advanced or metastatic pancreatic carcinomas,were enrolled between April 2000 and March 2002.Gemcitabine was administered by intravenous injectionat the doses of 1,000 mg/m2 on days 1, 8 and 15, and5-FU 800 mg/m2/day, was given by continuous intravenousinfusion on days 1~5. The treatment was repeatedevery 4 weeks. The clinical benefit response (CBR) wasa composite of the pain, Karnofsky performance statusand body weight change measurement.Results: Nineteen of the twenty patients were assessablefor response. The median follow-up duration was 4.6months (0.4~15.2 months). Five patients achieved a partialresponse and eight a stable disease. The overall responserate was 25.0%. The CBR was assessable in 12 patients.The overall CBR was 41.7% (5/12). The median survivalof all the patients was 8.0 months. Grade 3~4 toxicitiesincluded neutropenia (9.3%) and thrombocytopenia (5.3%).Conclusion: This study suggested that gemcitabine,combined with infusional 5-FU, was well tolerated, andproduced modest antitumor activity and symptomaticrelief in advanced pancreatic cancer patients.

A 55-year-old male was admitted to our hospital complaining of chest discomfort, dysphagia and severe pain on swallowing. Esophageal manometry identified the lower esophageal sphincter as having no response to swallow. Barium swallow showed typical esophagograms of double barrelled esophagus or mucosal stripe. An endoscopic examination revealed an appearance as if an esophago-tracheal fistula had been made at the level of the upper thoracic esophagus. Also, two slitlike mucosal tears were seen on the lower esophagus. Subsequent fasting and total parenteral nutrition for several weeks failed to bring about any improvement in his symptoms. So, as a treatment, primary closure of the upper opening of the false channel was performed under general anesthesia. Soon after the surgical procedure, the patients symptoms disappeared except for mild dysphagia. He was discharged after oral intake had been judiciously commenced with fluids and soft diets. During his follow-up in the out-patient department, he was examined and found to have no specific symptoms including fever or dysphagia. Moreover, there was great improvement from the massive dissection of the esophagus on esophagogram.

Gallium-nitride (GaN) nanorods (NRs) were selectively grown on patterned Ti/Si(111) substratesby using plasma-assisted molecular beam epitaxy. The effects of the growth temperature and the Gaflux on the optical properties of the GaN NRs were investigated. Both the length and the diameter ofthe GaN NRs decreased with increasing growth temperature whereas the diameter of the GaN NRsremained constant and the length increased with increasing Ga flux. The photoluminescence spectraof GaN NRs grown under different experimental conditions exhibited emission peaks correspondingto neutral-donor-bound excitons (DOX), donor-acceptor pair (DAP), and yellow luminescence (YL)bands at 3.477, 3.26, and 2.25 eV, respectively. Results demonstrate that the variation in thediameters of the GaN NRs has a greater influence on the defect concentration than the lengths ofthe NRs.

Colored tantalum oxy-nitride (TaON) and tantalum nitride ($Ta_{3}N_{5}$) were synthesized by ammonolysis. Oxygen deficient tantalum oxides ($TaO_{1.7}$) were produced by a titration process, using a tantalum chloride ($TaCl_5$) precursor. The stirring speed and the amount of $NH_{4}OH$ were important factors for controling the crystallinity of tantalum oxides. The high crystallinity of tantalum oxides improved the degree of nitridation which was related to the color value. Synthesized powders were characterized by XRD, SEM, TEM and Colorimeter.

Squamous cell carcinoma of the ovary is rare. It is considered to be associated with benign cystic teratoma, Brenner tumor and ovarian endometriosis which undergo malignant degeneration in their epithelial layers. Although ovarian metastasis from advanced
