충남 청양군 대치면 광대리 지역에 분포하는 조계리층에서 역과 혼재된 상태로 보존된 목재화석을 정리하던 중에 규화목과 함께 철광물로 충전된 목재화석이 혼합되어 있는 것을 발견하였다. 본 연구는 철화된 상태로 보존된 재목화석의 구성광물과 화학성분 및 성인에 대해 고찰한 것이다. 연구 지역은 선캄브리아기에 속하는 변성암을 기반암으로 하여 이를 부정합으로 덮고 있는 퇴적암층이 분포한다. 퇴적암은 하부로부터 조계리층과 백운사층으로 구분되며, 조계리층 상부의 역암대에서 재목화석이 산출된다. 규화목의 형태로 보존된 화석은 이미 백승덕(2003), Kim et al. (2005)의 분류학적 연구에 의해 Xenoxylon phyllocladoides, Agathoxylon sp.로 밝혀진 바가 있다. 재목화석의 구성광물을 알아보기 위해 보존상태가 좋은 5개의 표본을 골라서 XRF, XRD, 현미경 관찰을 실시하였다. XRF 분석 결과, 재목화석의 화학성분은 $Fe_2O_3$ (평균 83.18 wt.%)가 가장 높았고, $SiO_2$(평균 7.82 wt.%)로 가장 낮았다. XRD 분석 결과, 목재화석은 침철석(Goethite)으로 구성되어 있음이 밝혀졌다. 재목화석의 단면을 잘라 연마하여 현미경으로 관찰한 결과, 세포조직이 보존되어 있기는 하지만 보존 상태가 좋지 않아 분류를 하기에는 어려움이 있다. 더 많은 시료를 채집하여 현미경적인 연구가 필요하다. 침철석은 기반암, 염기성암체, 황화광물, 함철대의 풍화로부터 생성된 철염의 산화와 가수분해에 의해 생성된다. 목재가 퇴적암 속에 묻혀 화석화작용이 진행되는 동안에 같은 지역에서 규화작용과 철화작용이 동시에 진행된 것으로 판단된다.

Personal Health Record(PHR) service can be helpful to patients with diseases requiring strict everyday care and medical treatment, such as diabetes or cancer. In this paper, we propose a PHR system specialized in collecting and analyzing health record data of cancer patients, and present the process of how the system can improve the efficiency of cancer treatment process. Through the smart device application, cancer PHR system obtains daily PHR data which is highly related and critical to cancer therapy. The analysis report is provided to the medical staff with an available format suited for Electronic Medical Record used at medical institution. With the final result of PHR analysis which is easily merged with medical chart, most efficient Chemotherapy treatment can be provided for the patients. Also it is possible for the patients to give the information of side-effect and other pain experience during therapy to their doctors without loss of information. The proposed PHR system has the effect of improving the quality of patient care by allowing the medical staff to acquire the main objective data necessary for drug prescription and medical care benefits.

purpose: Image Guide System offers therapy precise, especially Intensity Modulated Radiation Therapy. However, organs at pelvis have variation and uncertainties each therapy. it brings IG system for verifying patient's position. In this study, analysis the variation at pelvis during rectal cancer radiation therapy. Moreover design the patient re-setup technique and apply to patients. Material and Method: 40 rectal cancer patient who have radiation therapy. The 530 image which acquired from IG system are analyzed. The bone structure, bladder, gas in the rectum, small bowel, soft tissue, weigh loss are evaluated by the criterion. The criterion are classified by best, good, bad and figure out the ratio with count. The re-setup proceed in case of one or over the two get the bad criterion and figure out the ratio of re-setup results: The ideal of therapy ratio is 19.2 % each criterion. And the good for therapy ratio is 54.9 %, the cases of bad for therapy is 25.8 %. The bad cases are have therapy after re-setup with post process. conclusion: Each pre-treatment image that acquired IG system has different results despite of same patients. The 25.8 % need to re-setup in order to unsuitable therapy. It is implies that the IG system is necessary establishing precise treatment plan like IMRT especially rectal cancer.

The effect of protein extract from Asterina pectinifera on breast cancer chemopreventive (aromatase and cyclooxygenase-2) and metastatic (matrix metalloproteinase) enzymes was tested. Protein extract from A. pectinifera was capable of suppressing aromatase in a human placenta microsomal assay. Cyclooxygenase-2 (COX-2) activity was significantly inhibited by the protein extract from A. pectinifera at concentrations of 10, 20 and $40{\mu}g/m{\ell}$. The extract markedly reduced 12-O-tetradecanoylphorbol-13-acetate (TPA)-stimulated matrix metalloproteinase (MMP)-9 activity. These results suggest that A. pectinifera could be of therapeutic value in preventing human breast cancer.

Purpose: Angiogenesis has a critical role in tumor proliferation, invasion, and metastasis. In gastric cancer, tumor-associated macrophages and mast cells produce angiogenic factors such as VEGF, that inhibit the functional maturation of dendritic cells. The aim of this study is to identify tumor-associated macrophages, mast cells, dendritic cell infiltrations, and microvessel densities (MVD) to investigate the relationship between them and the prognosis for gastric-cancer patients. Materials and Methods: The subjects were 79 patients selected from those who had undergone a curative gastric resection for stomach cancer. With them, Immune-histochemical staining was done using CD34 for the MVD, CD68 antigen for macrophages, and S-100 protein for dendritic cells, and toluidine blue staining was done for mast cells. Results: Macrophage infiltration showed a statistically significant positive correlation with histologic differentiation and a negative correlation with invasion depth, nodal metastasis, and stage. S-100 (+) dendritic cells and mast cells had no significant correlations with histologic differentiation, invasion depth, nodal metastasis, distant metastasis, stage, and MVD. As survival, no statistically significant differences were seen between the variables. Conclusion: Tumor-associated macrophages should be evaluated as possible prognostic markers in gastric-cancer patients.

Purpose: The best treatment for advanced esophageal cancer is chemoradiotherapy followed by surgery. In spite of the advance of multimodality therapy, most patients with esophageal cancer are treated with radiation therapy alone. This study reports the outcome of the use of conventional external beam radiotherapy alone for the treatment of esophageal cancer. Materials and Methods: Between January 1998 and December 2005, 30 patients with squamous cell carcinoma of the esophagus were treated with external beam radiotherapy using a total dose exceeding 40 Gy. Radiotherapy was delivered with a total dose of 44-60 Gy(median dose, 57.2 Gy) over $36{\sim}115$ days(median time, 45 days). Thirteen patients(43.3%) had a history of disorders such as diabetes, hypertension, tuberculosis, lye stricture, asthma, cerebral infarct, and cancers. Four patients metachronously had double primary cancers. The most common location of a tumor was the mid-thoracic portion of the esophagus(56.7%). Tumor lengths ranged from 2 cm to 11 cm, with a median length of 6 cm. For AJCC staging, stage III was the most common (63.3%). Five patients had metastases at diagnosis. Results: The median overall survival was 8.3 months. The survival rates at 1-year and 2-years were 33.3% and 18.7%, respectively. The complete response rate $1{\sim}3$ months after radiotherapy was 20%(6/30) and the partial response rate was 70%(21/30). Sixteen patients(53.3%) had an improved symptom of dysphagia. Significant prognostic factors were age, tumor length, stage, degree of dysphagia at the time of diagnosis and tumor response. Cox regression analysis revealed the aim of treatment, clinical tumor response and tumor length as independent prognostic factors for overall survival. Twenty-eight patients had local failure and another four patients had metastases. Three patients were detected with double primary cancers in this analysis. A complication of esophageal stricture was observed in three patients(10%), and radiation pneumonitis occurred in two patients(6.7%). Conclusion: The prognosis of esophageal cancer remains poor, in spite of advances in radiotherapy techniques. Radiotherapy is one of the main treatment modalities for the relief of dysphagia and treatment related complications are minimal. It is expected that the addition of chemotherapy or another systemic modality to radiotherapy will improve tumor control and increase the survival rate in advanced esophageal cancer.

Palliative sedation has been used in patients who undergo intractable suffering at the end of life. Its implementation, however, may be complicated due to resistance of clinicians and barrier of bioethical issues. Here, we present 50-year-old man with stomach cancer and multiple bone metastasis who was treated with palliative chemotherapy and radiotherapy. He suffered from refractory pain on the whole body even after standard analgesics and multidisplinary effort to relieve. Upon shared decision for sedation, he was given midazolam until discharge. Literature reviews reveal cases similar to the present case.

Colorectal carcinomas are extremely rare in childhood and adolescence; however, the colon is the most common site of a gastrointestinal carcinoma. Mucin secreting adenocarcinomas with signet ring formation is the most common type of colon cancer identified in children. An 11-year-old boy had abdominal pain and weight loss for three months, back pain and left thigh pain for two months, and hematochezia for four days. Colonoscopy showed an annular mass in the sigmoid colon and the histopathology revealed a signet ring cell carcinoma. A metastatic signet ring cell carcinoma was suspected from the findings of the bone scan, and confirmed later by a left scalp mass incisional biopsy and a bone marrow biopsy. We report a case of a metastatic signet ring cell carcinoma of the colon in a child.
