PURPOSE: The purpose of this study was to estimate the effects of a video low intensity exercise program provided during hemodialysis on fatigue, activity of daily living, positive psychological capital and blood pressure of patients being treated. METHODS: A non-equivalent control group pre-post test design was used. Participants were 85 hemodialysis patients assigned to either the experimental group (n=41) or the control group (n=44). The experimental group exercised for about 25 minutes 3 times a week for 8 weeks. Data analyses involved descriptive statistics, χ2 test, t-test, multiple regression and repeated measure ANOVA using SPSS/WIN 23.0. RESULTS: The exercise intervention significantly reduced post hemodialysis fatigue and significantly increased positive psychological capital. There was a significant interaction effect on time by group in blood pressure. Systolic blood pressure changes in the experimental group were stable but, changes in the control group tended to increase gradually. CONCLUSION: To reduce fatigue and increase positive psychological capital for hemodialysis patients, providing exercise during hemodialysis is recommended. Furthermore individualized exercise in terms of intensity, time, duration, etc should be developed and tested. Also, to reduce drastic blood pressure changes during hemodialysis, exercise should be provided.

BACKGROUND: Paraquat is widely used herbicide. But if it is ingested by accident or by suicidal attempt it causes severe toxicity. And in emergency room, it is a big problem that there is no effective treatment modality for paraquat intoxication. It is reported that the mechanism of toxicity is by oxygen fee radical. And Vitamin C is known as potent antioxidant. This study was designed to evaluate the antioxidant effect of Vitamin C to lipid peroxidaton in paraquat intoxication. METHODS: 24 rats were divided to 6 groups after paraquat injection(20mg/kg), and each groups 4 rats. In 2 control groups we only observed until 6 hours and 24 hours. And Vitamin C of 10 mg per kilogram body weight on the low dose group and 100 mg per kilogram body weight on the high dose group were infected simultaneously. And in 6 hours group, after 6 hours of paraquat and vitamin C injection biochemical levels of malondialdehyde, superoxide dismutase and catalase were measured in liver and lung. And in 24 hours group after 24 hours the same measures were done. The stasistical methods used were ANNOVA and Mann-Whitney test and P-value was 0.05. RESULTS: Malondialdehyde level of high dose Vitamin C group was significantly low compared to that of the control groups in liver tissues after 24 hours(p<0.05). And in lung tissues both low dose and high dose vitamin C groups show significantly low level of malondialdehyde level after 24 hours(p<0.05). On the superoxide dismutase activity, only high dose Vitamin C group shows significantly high level in 24hours both in liver and lung tissues. And the catalase activity is significantly elevated in high dome Vitamin C group after 24hours both in liver and lung tissues. (p<0.05) CONCLUSION: High dose Vitamin C suppresses lipid peroxidation, increases catalase activity and superoxide dismutase activity in paraquat intoxiation. It is thought to by antioxidant elect of vitamin C but it's effect is observed only in 24 hours after intoxication.

Alterations of genes are known to be critical for the induction of tumorigenesis, but the mechanism of ovarian carcinogenesis is little understood and remains to be elucidated. In this study, we investigated the roles of brca1, brca2 and p53 genes in the development of ovarian cancer using conditional knockout mice generated by a Cre-loxP recombinant system. Following the application of recombinant adenovirus expressing Cre in vitro, the proliferation of ovarian surface epithelium (OSE) was increased. For instance, a significant increase in cell growth was observed in OSE cells in vitro by conditional knockout isolated from the mice bearing concurrent floxed copies of brca1 and brca2/p53. However, the proliferative effect of the ovarian cells was not observed in concurrent brca1/brca2 or p53 knockout mice in vivo, indicating that we could not observe the direct evidence of the involvement of brca1, brca2, and p53 in ovarian carcinogenesis. Since morphological changes including tumor formation were not observed in mice bearing floxed copies of concurrent brca1/brca2 or p53, the inactivation of brca1/2 or p53 is not sufficient for the induction of tumor formation. Taken together, these results suggest that the deficiency of these genes may not be involved directly in the mechanism of ovarian carcinogenesis.

PURPOSE: We performed a pilot survey via internet to assess the prevalence of overactive bladder syndrome (OABs) and urinary incontinence(UI) in young and middle aged women. MATERIALS AND METHODS: From 22 April 2002 to 5 May 2002, a total of 3,372(89.8%) women(mean age: 26.3+/-4.8 years) among 3,757 participants completed a questionnaire via internet web site. They were divided into 3 groups: those who had OABs(group 1), who had UI(group 2), and controls who had neither. The factors related to OABs and UI were analyzed by multiple logistic regression analysis. RESULTS: Of 3,372 respondents, the prevalence of OABs and UI in young women was 429(12.7%) and 707 (21%), respectively. The factors related to OABs were history of urinary tract infection and family history. The factors related to UI were age, occupation, history of urinary tract infection, family history, and parity. CONCLUSIONS: The symptoms suggestive of OABs and UI are highly prevalent in young and middle aged women. So, effective healthcare polices and prompt management about OABs and UI should be concerned.

BACKGROUND/AIMS: Hypothyroidism has been reported in 36~85% of patients treated with sunitinib for renal cell carcinoma or gastrointestinal stromal tumor. However, the mechanism behind this hypothyroidism is unclear. This study evaluated the effects of sunitinib, a multi-target tyrosine kinase inhibitor, on the survival and proliferation of thyrocytes using FRTL-5 rat thyroid cells. METHODS: We examined the effect of sunitinib on cell proliferation in the presence and absence of thyroid stimulating hormone (TSH) in a colorimetric assay. Effects on the cell cycle were evaluated by flow cytometry, and on apoptosis using an annexin V apoptosis assay kit and by immunoblotting for caspase-3. Immunoblotting was also used to evaluate changes in the levels of intracellular proteins associated with the G1-S phase of the cell cycle. RESULTS: Sunitinib suppressed the proliferation of FRTL-5 cells in a dose- and time-dependent manner. This suppressive effect was enhanced by the presence of TSH (1 mU/mL). Sunitinib was subsequently shown, in flow cytometric analyses, to arrest the cell cycle at the G1-S phase. Furthermore, it induced apoptosis at a high concentration (15 micrometer) by activating caspase-3. G1-S phase arrest was associated with the induction of p27(kip1) and p21(cip1), whose expression is suppressed by TSH under control conditions. Sunitinib also decreased intracellular levels of cyclin D1 and cyclin-dependent kinase 2 in FRTL-5 cells. CONCLUSIONS: Sunitinib induced apoptosis in and suppressed the proliferation of FRTL-5 cells. Its suppression of proliferation was further enhanced by the presence of TSH. Sunitinib arrested the cell cycle in the G1-S phase by inducing the expression of p27(kip1)/p21(cip1), which are suppressed by TSH under normal conditions. Collectively, these findings suggest that sunitinib may interfere with TSH signaling pathways in normal thyrocytes.

Radiofrequency ablation (RFA) is a popular technique and shows excellent local tumor control and acceptable morbidity. Although RFA is considered much safer than surgical treatment, it is not a complication-free procedure. The most common complications of percutaneous RFA areabdominal hemorrhage, abdominal infection (abscess), biliary tract damage, and ground-pad burns. Laparoscopic RFA (LRFA) is a safe, feasible treatment modality to achieve tumor destruction. LRFA has proven superior to the percutaneous approach for lesions that are difficult or impossible to treat percutaneously. Needle-track implantationafter LRFA is a rare complication in HCCs. We report a case of needle-tract implantation of HCC found in the chest wall, ribs,and diaphragm 11 months after LRFA in a 49-year-old man. Although treatment for needle-track implantation is not well established, the metastatic mass was surgically removed.

Gastric lymphoepithelioma-like carcinoma is a rare carcinoma among gastric malignant tumor but has a good prognosis. The carcinoma has histologic feature characterized by small nest of cancer cells mixed with lymphoid stroma. We report a case with lymphoepithelioma-like carcinoma of stomach initially presenting as panperitonitis because of spontaneous tumor perforation. A 56-year-old man visited our emergency room because of epigastric pain. A preoperative abdominal CT scan showed a massive pneumoperitoneum in the upper abdomen, and the presence of gastric cancer in the lesser curvature of the stomach. An emergent laparotomy was performed followed by radical subtotal gastrectomy. Pathologic examination revealed that the tumor was a lymphoepithelioma-like gastric carcinoma.

Using IC cards with powerful information processing capabilities, high level of security, and multi media capabilities to create health IC cards has the following merits: comprehensive management of individual medical information, highly secure access to information that may be stored in separate location and/or institutes, increasing the compatability of difference used by various institutes. In this research ,we have categorized the information stored in the health IC card into the following main categories: basic personal information, emergency medical information, medical informatics, nursing information, welfare information. This was based on international ISO standards and specifics of Japan and south eastern Asia. These main categories are further divided into sub-categories and care was taken to ensure that the format of each sub-category is compatible with international standards while being suitable for Koran conditions of actual use. So, these categories conform to international standards and we will continue our efforts update the international standard to include additional categories needed in Korea and update the Korea standard to conform more closely with the international standards.

Recent developments in computer and communication technology were studied in relation to medical information network systems, using computers and IC cards, to solve problems in community health. Trial use of health IC card systems for personal health data management are already in existence in some countries. The health IC card system provides good quality information to the doctors, the hospital, the patients, and the insurance organizations. Emergency medical information card systems that take advantage of advanced information-related technologies such as computers and communication systems, in order to improve their emergency medical care systems may have many advantages. Emergency medical information card can provide a way to protect people during medical emergencies by providing physicians with their vital medical information during the critical seconds of emergency care if being unable to provide your vital medical information. Before introducing these systems, recognition that an important problems such as standardization of the data and code for the medical information systems, defining the access and usage rights by user profiles and the types of data for the security and data protection must be considered. We studied the emergency medical information card systems to clarify their purpose, analyse their present status, standardize the data and codes and define the access and usage rights and present the ideal system, in view of community health care requirements. Here the results of the research are examined, and there is a discussion of what is needed to use the emergency medical card system in the future.
