To determine phylogenetic relatedness of four silk-producing silkmoths (B. mori, B. mandarina, A. yamamai and A. pernyi), internal coding region of arylphorin which is a storage protein in hemolymph protein of insects were amplified by polymerase chain reaction and then sequenced and compared each other. The nucleotide composition was biased toward adenine and thymine(59% A+T) and a strong bias for use of C in the third position of codons was found for Phe and Tyr. Together TTC(Phe) and TAC(Tyr) account for about 16.8% (10 for TTC and 8 for TAC) of all codon usage. The nucleotide similarity of arylphorin gene from B. mori showed 99%, 98% and 97% homology with those of B. mandarina, A. yamamai and A. pernyi, respectively. Also, the nucleotide sequence of arylphorin gene from B. mandarina showed 98% and 97% homology with those of A. yamamai and A.pernyi, respectively. Between A. yamamai and A. pernyi, the sequence homology was 97%. The deduced amino acid sequences in B. mori, B. mandarina and A. yamamai showed almost 99% homology. Although the aryphorin gene provided insufficient variability among the four insect species, A UPGMA tree is generated that supported the monophyly of silk-producing insects, with M. sexta placed basal to it. It is suggest that silk-producing insects have a close relationship and a homogeneous genetic background from comparison with those of other insects.

The aim of this study was to compare medical cost of hospice care and that of conventional care during the last year of life, and identify factors that influenced the cost. From January to August 2003 592 terminal cancer patients receiving care from 5 hospice care units and 2 hospice care teams in general hospitals were enrolled to case group. Two hundreds and seventy two terminal cancer patients receiving conventional care from 7 general hospitals were enrolled to hospital-based control group, and 1,636 terminal cancer patients from 122 general hospitals located in same regions with the 7 hospitals were enrolled to community-based control. We used characteristics and medical cost from data of National Health Insurance Cooperation. Total medical cost per beneficiary in cases was about 10 millions won, 14.5 millions in hospital-based controls and 11.1 millions in community-based controls. The hospice care saved $45\%$ over the last year of life compared with hospital-based controls (p<0.0001). Saving of inpatient cost account for approximately $80\%$ of saving per beneficiary. Hospice care saved $29\%$ of medical cost per hospitalization day compared with hospital­based controls and $17\%$ compared with community-based controls (p<0.0001). Multiple regression analyses showed that hospice care significantly saved the medical cost. This study suggest that hospice care save medical cost compared with hospital-based control and community-based control. Most of saving of inpatient cost account for approximately $80\%$ of saving of medical cost.

Purpose：This is a retrospective study to evaluate the results of concurrent chemoradiotherapy in nasopharyngeal carcinoma. Material and Methods：From Mar 2000 to June 2005, 18 patients with nasopharyngeal carcinoma completed planned concurrent chemoradiotherapy. Stages were I in 1 patients, II in 2 patients, III in 7 patients and IV in 8 patients. Pathologic type was squamous cell carcinoma(WHO type 1) in 2 patients, non-keratinizing type(WHO type 2) in 8 patients and undifferetiated carcinoma(WHO type 3) in 8 patients. The follow up period ranged from 30 months to 95 months with a median of 56 months. Follow up was possible in all patients. Results：Response to concurrent chemoradiation therapy was a complete response in all patients. Patterns of failure were as follows：local recurrence in only one patient(5.6%) and distant metastases in three patients with N3 diseases(16.7%). The overall 5 year survival rates were 88.5%, the 5 year disease free survival rate was 77% and these were very good results. There were no significant differences in the local control and survival rates between the clinical stages and pathologic types. Conclusion：The outcome of the nasopharyngeal carcinoma treated with concurrent chemoradiotherapy was very good, even though most of the patients(15/18=83.3%) were in stage III and IV diseases. We concluded that concurrrent chemoradiotherapy in nasopharyngeal carcinoma showed the good local control and survival rates without significant complications. In the patients with N3 disease, we have to consider the more effective and strong chemotherapeutic regimens to prevent distant metastases.

To investigate the causes of emaciation in cultured olive flounder Paralichthys olivaceus in Korea. We performed histological examinations and polymerase chain reaction (PCR) with a new primer set. In most cases, the most severe emaciation was observed in the abdominal area Using PCR on extracted livers, kidneys, spleens, gills, brains, and intestines, we found that areas around the kidneys and intestines were as almost always positive. In significantly emaciated fish, PCR was positive in all internal organs except the gills. In addition, the homology of 812-bp nucleotide sequences of the 28S rRNA gene was more than 99% in emaciated fish. Partial homology with Myxobolus spp. and Cystodiscus axonis, whose data were obtained from GenBank was 86% and 88%, respectively. Histological examinations detected spores in kidneys and intestines but not in other organs. We also performed cohabitation experiments to determine whether infections could be exchanged among species or only within species. Uninfected olive flounder and red sea bream, Pagrus major, cohabitating with emaciated olive flounder showed 100% and 0% cumulative mortality, respectively. Thus the cause of emaciation in cultured olive flounder of Korea is likely due to a new parasite.

A malignant sarcoma of soft tissue that arises near but not in a joint, most often in an adolescent or young adult, is typically slowgrowing, and may escapes notice until it causes pain. The diagnosis of this tumor can be suspected by X-ray or imaging, made by biopsy, and confirmed by chromosome studies. Cytogenic studies reveal a translocation between the X chromosome and chromosome 18 in the tumor cells. The most common treatment for the tumor is surgery to remove the entire tumor, nearby muscle, and lymph nodes. Synovial sarcoma tends to recur locally and to involve regional lymph nodes. Distant metastasis occurs in half cases. The well-documented and adequately followed cases are currently lacking and this report described an instance of Synovial sarcoma good result after treatment and review of literature.

Background: The polymerase chain reaction (PCR) test is important for the confirmatory diagnosis of tuberculosis (TB) caused by Mycobacterium tuberculosis. The aim of this study was to analyze the yield of repeated PCR testing in patients with confirmed pulmonary TB. Methods: The medical records of 130 patients, who had more than two consecutive PCR tests and a M. tuberculosis-positive sputum culture from August, 2006 to December, 2007, were retrospectively reviewed for the purposes of this study. A positive TB-PCR test was defined as at least one positive test result. Results: The cumulative positive PCR test rate was 80% (104/130), with gradually increasing rates of positive findings upon the first, second and third TB-PCR tests with 52.3%, 68.5% and 75.4%, respectively. However, further testing did not increase the positive rate further. Conclusion: Repeated PCR testing at least three times for M. tuberculosis is helpful for diagnosis of pulmonary TB.

Objectives : An aim of study is to investigate effects of curculiginis rhizoma in vitro (factor Xa (FXa) inhibitor assay, prothrombinase assay, prothrombin time (PT) assay, activated partial thromboplastin time (aPTT) assay) and in vivo experiment (blood clotting time, thromboxane B2 content assay in serum and weight of thrombus by AV-shunt rat model). Methods : We gained a human serum and used serum in vitro study such as factor X activity (FXa) inhibition, prothrombinase inhibition, prothrombin time (PT) and activated partial thromboplastin time. Fifteen SD rats were divided into three groups (intact control group and two experimental group treated with extract of Curculiginis Rhizoma(ECR)). Rats were orally administrated DW (intact control group), 600 mg/kg concertration of ECR and 200 mg/kg concertration of ECR. After one hour, we anesthetized rats and made arteriovenous (AV) shunt rat models to study weights of thrombus, took a hole blood to study content of thromboxane B2 and blood clotting time. Results : In vitro, ECR increased a inhibitory activity of FXa, prothrombinase and aPTT compared than intact control group. Especially ECR made significant increase of FXa and prothrombinase inhibitory activity (p<0.05, p<0.01). And PT were increased in ECR control group compared with intact control group. In vivo, a blood clotting time of experiment group treated with ECR 600 mg/kg were significantly increased compared with that of intact control group (p<0.05) and content of thromboxane B2 was significantly decreased in group treated with ECR 600 mg/kg in seum. The weight of thrombus were significantly reduced in group treated with ECR 600 mg/kg compared with intact control group (p<0.05). But in vivo experiment study, those of group treated with ECR 200 mg/kg were reduced compared with those of intact control group without statistical significance. Conclusions : ECR has a antithromboic activity in internal course with inhibitory activity of FXa and prothrombinase in vitro, it required to research more study for effective compounds.

Background: Muscle weakness and impaired trunk muscle control are common in stroke patients. The bridging exercise (BE) is generally used for trunk stabilization and improving the overall function of stroke patients. The effectiveness of the BE with hip adductor contraction (BEHA) in facilitating trunk muscle activation has been well studied in healthy adults. However, the impact of BEHA in sub-acute stroke patients has not yet been investigated. Objects: The purpose of this study was to determine the effects of BEHA on the electromyography (EMG) activities and the asymmetry of the rectus abdominis (RA), external oblique (EO) and internal oblique (IO) abdominal muscles. Methods: Twenty participants with sub-acute stroke (11 males and 9 females) were recruited. Each participant was asked to perform bridging exercises for five seconds under three different conditions: BE in a neutral position (BEN), BEHA with a large ball (BEHAL) and BEHA with a small ball (BEHAS). The EMG amplitudes of the bilateral RA, EO and IO and the asymmetry of the EMG activity between the sound and affected sides were compared among the conditions. The significance level was set at ${\alpha}=.05$. Results: The EMG activities of RA, EO and IO were significantly greater during BEHAL and BEHAS than during BEN (p<.05); the asymmetry of the RA, EO and IO decreased significantly during BEHAL and BEHAS compared to BEN (p<.05). However, no measured variables showed any significant differences between BEHAL and BEHAS (p>.05). Conclusion: This study compared the EMG activities of the RA, EO and IO on both sides and the asymmetry of the RA, EO and IO during BEN, BEHAL and BEHAS. Our findings suggest that BEHA was more effective for individuals with hemiplegic stroke at facilitating and normalizing abdominal muscle control than BEN.

Since 2006, the Computerized Restricted Antibiotic Control Program (CRACP) has been incorporated to facilitate a more efficient approval process of vancomycin use at the Chonbuk National University Hospital. The purposes of the study were to evaluate proper use of vancomycin and to examine if there is any improvement when administering the CRACP. The use of vancomycin was retrospectively reviewed by a medical record review based on the American Society of Hospital Pharmacists (ASHP) criteria (i.e., indication, use of critical process indicators and use of outcome measurements) and compared before (Group I) and after the CRACP (Group II). Two hundred fifty six patient records were evaluated (138 in Group I and 118 in Group II). There was a statistically significant improvement in the report of justification for vancomycin use after CRACP (42.0% vs. 62.7%, p=0.001). Out of eight critical process indicators, two indicators (appropriate cultures prior to medication [68.8% vs. 85.6%, p=0.002] and serum vancomycin level measurement [0% vs. 7.6%, p=0.001]) were significantly improved after CRACP. The total incidence of adverse effects was decreased from 14.5% to 6.8%. In addition, there was a statistically significant difference in WBC count reduction within normal range (52.8% vs. 73.1%, p=0.024). The CRACP appears to be a promising approach to improve use of vacomycin in a hospital setting. However, further evaluation for the long-term period should be performed to confirm the performance of the program.

This study was conducted to clarify the effect of physical ability, pain, fatigue, depression, sexual satisfaction, and spouse criticism on the sexual intrusiveness of rheumatoid arthritis(RA)women. The subjects of the study were 89 RA outpatients who visited the department of rheumatology of Dong-A University Hospital in Pusan from March 2000 to April, 2000. Pain & Fatigue via graphic rating scale, depression via CES-D(Center for Epidemiologic Studies -Depression) scale and physical ability via the Health Assessment questionnaire(HAQ) were assessed. Also we used both Sexual satisfaction scale(Kim, et al, 1997) to measure sexual satisfaction and Spouse criticism scale(Kraaimaat et al. 1996) to measure spouse criticism. The Intrusiveness rating scale which was derived from Arthritis Impact Measurement Scale(AIMS) was used to measure illness intrusiveness in sexuality. The relationships between the variables such as pain, depression, fatigue, physical ability, spouse criticism, sexual satisfaction and illness intrusiveness on sexuality were analyzed by Pearson correlation. As a result, pain & depression were significantly positively related to illness intrusiveness and physical ability & sexual satisfaction was significantly negatively related to illness intrusiveness. But these variables were interrelated. So hierarchical regression was performed to examine the relative contribution of pain, depression, physical ability, and sexual satisfaction with regard to intrusiveness of RA on sexuality. It revealed that pain, depression & sexual satisfaction predicted significantly illness intrusiveness on sexuality. Therefore it is very important to reduce pain and depression and to increase sexual satisfaction for reducing illness intrusiveness.
