Hepatocellular carcinoma frequently metastasizes through direct extension, lymphatic, and hematogenous routes. The most common sites of metastasis are the lungs and the lymph nodes, glands, bones, spleen, kidneys, colon, and pleura are the sites of metastasis in decreasing order of frequency. But metastasis to the ovary is very rare. It is thought that metastasize to the ovary occurs through infiltration or dissemination. However, we observed ovarian metastasis of primary hepatic tumor in a 34-year old female who suffered from lower abdominal pain. At first, it was diagnosed as a primary ovarian tumor. But histologically, it presented sinusoidal pattern surrounded by the tumor cells and contained rounded by the tumor cells and contained round hyaline globules in minority of the cytoplasm. Then, the histologic features of percutaneous, sono-guided liver biopsy speecimen of the liver mass are similar to those of resected ovarian tissues. Therefore, we concluded that ovarian tumor was originated from hepatocellular carcinoma. In summary, this report examines a case of hepatocellular carcinoma with ovarian metastasis in a female and reviews the literature.

Walter Byers, the NCAA Executive Director from 1951 to 1987, coined the term 'student-athlete' in 1973. This phrase has since become widely recognized on college campuses and within society, and implies dual and separate role of being both a student and an athlete. As the term implies, these individuals attend college for two main reason: to make progress towards a college degree and to participate in intercollegiate athletics. The purpose of this study was to investigate factors influencing role conflict on personal attributes, athletic performance and role salience among collegiate student-athletes. The sample was drawn from 821 student-athletes who involved in intercollegiate athletics at the university located in Seoul and Kyunggido and enrolled in Korea Sports Council. They were selected by the method of stratified cluster random sampling. A survey was undertaken from 2003, using the self-administration method. All of questionnaires were personally delivered to the respondents, who immediately filled them out. t-test, one-way ANOVA, multiple regression were used to test and analysis the proposed model in the study. The findings of this study were as follow: 1. Female athletes shows greater cognitive and empirical status role conflict and load conflict, cognitive self role conflict, and empirical student-athlete role conflict than male athletes, three years athletes shows greater cognitive and empirical student-athlete role conflict than any other years athletes, and athletes with high level of life shows cognitive self role conflict and empirical student-athlete role conflict than any other athletes with love of life. 2. Athletic success influence cognitive self role conflict, and playing career has effect on empirical student-athlete role conflict. 3. Relative knowledge related in role of student and athlete has effect on all of cognitive and empirical role conflict, relative time spent in role of student and athlete has effect on cognitive status role conflict, cognitive and empirical load role conflict, and empirical student-athlete role conflict. And relative values of role of student and athlete has effect on cognitive and empirical status role conflict, cognitive and empirical load role conflict, empirical self role conflict and empirical student-athlete role conflict, and relative devotion in role of student and athlete has effect on cognitive self role conflict. status role conflict, load role conflict, and student-athlete role conflict, And satisfaction with student role has effects on cognitive self role conflict, and empirical status role conflict and load role conflict.

The authors experienced 6 cases of Dimecron intoxication, an organophosphate, that required mechanical ventilator treatment. Among 6 cases, 4 cases were intoxication due to suicidal attempt and 2 cases were due to accidental exposure. Among 4 cases of intoxication due to suicidal attempt, only one patient recovered even after aggressive treatments using gastric lavage, mechanical ventilation, atropine and PAM(pralidoxime). Two cases of intoxications due to accidental exposure, 1 case needed mechanical ventilation. Both cases were recovered without any sequele, however. Organophosphate, especially Dimecron, showed high rates of resfiratory muscle paralysis and mechanical ventilator support. The mortality rate of organophosphate agents can be decreased by education, wearing protectors, and aggressive mechanical ventilator treatment when respiratory failure develops.

Evans syndrome is defined as a simultaneous or sequential occurrence of autoimmune hemolytic anemia and autoimmune thrombocytopenia. Autoimmune hemolytic anemia (AIHA) is usually induced by IgG warm autoantibody or cold-active IgM antibodies reacting specifically with antigens associated with a patient's RBC. AIHA is a fairly uncommon disorder, with estimates of the incidence at 1 to 3 cases per 100,000 per year. Mixed-type AIHA is a relatively uncommon form of AIHA, with studies noting the incidence of 7-8% among cases of AIHA. We experienced a patient, 46-year-old woman who was diagnosed having a very rare clinical presentation of mixed warm and cold antibody mediated Evans syndrome. She was treated with corticosteroid therapy only and has been maintaining a complete response for 15 weeks. 저자들은 혼합형의 자가면역성 용혈성 빈혈과 자가면역성 혈소판 감소증이 동시에 발생한 혼합형 Evans 증후군으로 진단하고 스테로이드 요법 후 혈액학적으로 회복된 상태로 15주가 지난 현재 steroid 5 mg/일 까지 감량한 상태에서 추적 관찰 치료중인 46세 여자 환자를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.

Objective: The Lispro insulin has faster onset of effects and shorter duration than the human regular insulin, an analog of human insulin. The differences in the pharmacodynamics between the two types of insulin in the continuous subcutaneous insulin infusion(CSII) with insulin pump for treating the Korean Type 2 DM patients were analyzed. The effects on the regulation of blood sugar, the amount of insulin injected, and the frequency of hypoglycemia were compared between the lispro insulin and the regular human insulin. Method and Material: One hundred and three Korean Type 2 DM patients were randomly divided into two groups, 49 Lispro insulin and 54 Regular insulin.(Table 1) Both groups were treated for 14 days. Also at a set time before meal, insulin was injected as bolus, using a portable insulin pump, in both groups, 15 minutes before for lispro insulin and 30 minutes before for human insulin The HbA1C, C-peptide, AC/PC, height and weight were measured for each patients at the time of admission. The peripheral blood sugar level and insulin injection profile were recorded 7 times per day for each patients. Results: After treating for 7 days and 14 days, the blood sugar level normalized in both groups. There weren't any significant differences in blood sugar levels in both groups at point of the study, and also there weren't any differences in the frequency of hypoglycemia. In order to maintain the normalized blood sugar level, the lispro insulin group had higher total daily insulin requirement than the regular insulin group after 14 days of treatment (0.90±0.35 vs 0.73±0.39u/kg/day, p<0.05) This difference is probably due to the difference in basement insulin requirements rather than prandial insulin requirements (0.32±0.1 vs 0.43± 0.09u/kg/day, p<0.001). Discussion: In the hospitalized Korean Type 2 DM patients with CSII treatment, continuous subcutaneous insulin infusion therapy using lispro insulin has convenience in usage compared to the regular insulin. However, there were not any differences in the blood sugar levels. Also lispro insulin requires more insulin in order to maintain normal blood sugar level, which is probably due to the increase in the basal requirement. Also there were not any difference in the frequency of hypoglycemia.

Choriocarcinoma associated with a normal pregnancy is rare. Especially, choriocarcinoma coexistent with a viable pregnancy is even rarer and commonly presents with widespread metastatic disease. We experienced a patient at 34th week of pregnancy with dyspnea and sputum production due to pulmonary metastasis of choriocarcinoma. The serum B-hCG level was extremely elevated and the placenta had multifocal choriocarcinoma. After vaginal delivery, the patient was successfully treated with combination chemotherapy (EMA-CO). The patient is receiving follow up with monthly measurement of hCG values. We report one case of metastatic choriocarcinoma with viable pregnancy with review of literature.
