Some siphonophores were collected from the Korea Strait, $33^{\circ}59'N-129^{\circ}17'E$ and Yeosu with Issacs-Kidd Midwater trawl net in Sep. 2002. They were identified into Diphyes chamissonis is Huxley, 1859 and Abylopsis eschscholtzi(Huxley, 1859) in the suborder Calycophorae of the order Siphonophora, respectively. They are new to the Korean fauna. As a result of this work, six siphonophores of four families have been reported in Korea.

To determine the correlation between the response to induction chemotherapy and subsequent radiotherapy we analyzed the clinical records of 60 patients with locally advanced carcinoma of the head and neck retrospectively who had completed a full course ($2\~3$ cycle) of induction chemotherapy and curative radiotherapy in Korea Cancer Center Hospital between 1986 and 1989. Chemotherapy was administeredd with CDDP+Bleomycin (BP) in 20, CDDP+5-FU (FP) in 37, and hybrid of BP and FP in three patients. Radiotherapy was giver conventionally with a dose of 65 to 75 Gy or more over seven to eight weeks according to the size of lesion. Response rates following induction chemotherapy were $80\%$ for the tumors and $879\%$ for the nodes whereas complete reponse rates were $12\%\;and\;13\%$, respectively. Six months after radiotherapy $67\%$ of the tumors and $77\%$ of the nodes achieved a complete response. Among the 48 tumor responders and the 31 nodal responders to chemotherapy,39 ($81\%$) and 28 ($90\%$), respectively, achieved complete response after radiotherapy. Thus, whether or not the tumor and node respond to induction chemotherapy was predictive of the response to subsequent radiotherapy (p<0.0005 in tumor, p<0.0001 in node). By reanalyzing according to disease subsets (i.e. primary site, T-stage, N-stage) this relationship was not observed at T1-T2 disease (p>0.3). Therefore the tumor or node's response to induction chemotherapy is a predictor for subsequent radiotherapy except in T1-T2 tumors, and complete response to radiotherapy can be expected despite the failure of induction chemotherapy in $T_1-T_2$ tumors.

Purpose:Medical therapy is the initial treatment for children with Graves disease to avoid complications of other treatments. However, optimal treatment for childhood Graves disease is controversial because most patients require relatively long periods of medical therapy and relapse is common after medication discontinuation. Therefore, this study aimed to search clinical or biochemical characteristics that could be used as remission predictors in Graves disease. Methods:We retrospectively studied children diagnosed with Graves disease, treated with anti-thyroid agents, and observed for at least 3 years. Patients were categorized into remission and non-remission groups, and the groups were compared to determine the variables that were predictive of achieving remission. Results:Sixty-four patients were enrolled, of which 37 (57.8%) achieved remission and 27 (42.2%) could not achieve remission until the last visit. Normalization of thyroid-stimulating hormone-binding inhibitory immunoglobulin (TBII) after treatment was faster in the remission group than in the non-remission group (remission group, $15.5{\pm}12.07$ vs. non-remission group, $41.69{\pm}35.70$ months). Thyrotropin-releasing hormone (TRH) stimulation tests were performed in 28 patients. Only 2 (8.3%) of 26 patients who showed normal or hyper-response in TRH stimulation test relapsed. Binary logistic regression analysis identified rapid achievement of TBII normalization after treatment as a significant predictor of remission. Six percent of patients achieved remission within 3 years and 55.8% achieved it within 6 years. Conclusion:Rapid achievement of TBII normalization can be a predictor of remission in childhood Graves disease. The TRH stimulation test can be a predictor of maintenance of remission.

Purpose : Due to its high potency against leukemic blasts, our institution has opted for the use of dexamethasone during acute lymphoblastic leukemia (ALL) remission induction, but in our most recent treatment protocol, CMCPL-2005, we shortened the length of steroid treatment from 4 to 3 weeks. We compared both the rates of remission induction and significant complications observed during induction with CMCPL-2005, with those noted for our previous protocol, CMCPL-2001. Methods : We retrospectively reviewed the records of patients diagnosed with ALL from January, 2001 to December, 2006 at the Department of Pediatrics, St. Mary's Hospital, the Catholic University of Korea. Data concerning age, sex, WBC count at diagnosis, immunophenotype, cytogenetic traits, and risk group were collected for each patient. Results of remission induction treatment were compared between the two patient groups. Infection and other major complications resulting from treatment were investigated according to NCI toxicity criteria. Results : A total of 141 and 88 patients received remission induction under CMCPL-2001 and CMCPL-2005 respectively. In the CMCPL-2001 group, 136 (96%) achieved complete remission while 82 (93%) achieved CR in the CMCPL-2005 group. Patients in the CMCPL-2005 group were more likely to undergo remission induction without experiencing major complications. However, with regards to steroid related toxicities such as infection, no significant differences were noted. Conclusion : We shortened the length of steroid administration from four to three weeks, yet found the remission induction rate to be comparable to that of our previous regimen. However, rates of steroid related toxicities such as infectious complications remain unchanged despite shortened exposure to dexamethasone.

Spontaneous regression is extremely rare in lung cancer and this in spite of its global high incidence. So far, less than 30 such cases have been reported in the literature. We report here on the case of a 68-year-old man who had the diagnosis of adenocarcinoma and in absence of any medical therapy, he had a partial spontaneous regression of tumor.
