Acinar cell carcinoma is a rare tumor that represents 1~2% of al1 pancreatic cancers. Clinical and radiologic findings are inconclusive in this disease Acinar cell carcinoma is characterized by rapid progression and early metastasis, which lead to its poor prognosis. A 41-year-o1d man was admitted to our hospital for abdominal pain. Abdominal computed tomography (CT) and positron emission tomography-computed tomography (PET-CT) showed a splenic mass, which was being invaded by a pancreatic tail mass and which had increased ^(18)F-fluorodeoxyglucose (FDG) uptake Primary radical distal pancreatectomy and splenectomy were performed. Pathologic findings revealed an acinar cell carcinoma of the Pancreas The patient underwent a total gastrectomy three months later because of gastric recurrence Four months later, multiple hepatic metastases were discovered, and the patient underwent a left hepatectomy During treatment with capecitabine, there was no evidence of tumor progression for 14 months. We report a case of metastatic pancreatic acinar cell carcinoma, which did not progress for an extended period while the patient was being treated with capecitabme.

Primary retroperitoneal mucinous cystadenocarcinoma is a very rare malignancy, and little is known concerning its Pathogenesis, optimal treatment, and prognosis. A 29-year-o1d pregnant woman (21 weeks) Presented with abdominal discomfort CA 19-9, CA 125, and CEA were normal Abdominal CT scanning revealed a 19x15x13 cm retropentoneal tumor Exploratory laparotomy and tumor excision were performed. Mucinous retropentoneal implants were removed as completely as possible Histologically, the tumor showed focal areas of capsular invasion, but free resection margins The uterus and both ovaries were normal in appearance No adjuvant therapy was pursued. Six months later, Peritoneal and bilateral ovarian metastases were discovered. Hence, we report the details of this case of primary retroperitoneal mucinous Cystadeno-carcinoma and present a review of the literature.

The growth characteristics according to temperature conditions were investigated in the breeding room of the Sericulture & Entomology Experiment Station for Oriental garden crickets(Teleogryllus emma Ohmachi et Matsuura) and Modeagali-crickests(Loxoblemmus doenitzi Stein) collected from the lawns of Byeonsan-myeon, Buan-gun, Jeollabuk-do. The temperature conditions were 6 treatments from 15°C to 40°C at 5°C intervals using a multi-incubator, and the development period and mortality rate by age were compared using the 28°C breeding room conditions as a control. For T. emma, the higher the temperature, the shorter the total development period was, and the same trend was observed for the growth period by age stage. However, at low temperatures of 15°C and 20°C, all died after the third instar, and at high temperatures above 35°C, all died during development. At 25°C and 30°C, they developed normally, and the mortality rate was about 25%. The L. doenizi had the same tendency as the T. emma, with the higher the temperature, the shorter the development period. The total development period was 57.7 days at 25°C, which was similar to the T. emma's 55.9 days, and the mortality rate was the lowest at 44% at 25°C.

<P>Individuals who traveled to contaminated areas after the Fukushima nuclear accident have concerns about the health effects. However, medical follow-up for any adverse health effects will be difficult without personal dose measurements. Cytogenetic biodosimetry is a reasonable method of assessing absorbed doses retrospectively. We analyzed dicentric chromosomes for 265 Fukushima travelers, mostly journalists and rescue workers, who had been dispatched to northeastern Japan during the nuclear emergency. As a control group, 37 healthy volunteers who had not visited Japan since the accident were enrolled. Yields of dicentrics and absorbed doses calculated from a dose-response calibration curve for travelers and the control group were compared. The cut-off level for dicentric chromosomes in the controls was 3.5 per 1000 cells. Of the 265 travelers, 31 had elevated numbers of dicentrics (High-Dics group) while 234 were below the cut-off (Normal-Dics group). All but one of the individuals in the High-Dics group also reported a significantly higher number of medical exposures to radiation within the past three years compared with the Normal-Dics or control groups. The 225 travelers with no history of medical exposure showed no difference of dicentrics yield compared to the control group. Our data indicate that Fukushima travel alone did not enhance the yield of dicentrics.</P>
