Sustained-releasing praziquantel (SRP) tablet was designed for single dose treatment regimen of clonorchiasis. A previous pre-clinical study confirmed its sustained-releasing characteristics and a better cure rate than conventional praziquantel (PZQ). In this clinical study, the pharmacokinetics of this SRP tablet were investigated in human volunteers (phase 1; 12 volunteers), and its curative efficacy was examined in clonorchiasis patients (phase 2; 20 volunteers). In the phase 1 clinical study, blood concentrations of both tablets showed wide individual variation. The $AUC_{last}$ of SRP was $497.9{\pm}519.0ng{\cdot}hr/ml\;(mean{\pm}SD)$ and PZQ of $628.6{\pm}695.5\;ng{\cdot}hr/ml$, and the $AUC_{inf}$ of SRP was $776.0{\pm}538.5\;ng{\cdot}hr/ml$ and of PZQ $658.6{\pm}709.9\;ng{\cdot}hr/ml$. $C_{max}$ values of SRP and PZQ were $90.7{\pm}82.2ng/ml\;and\;214.9{\pm}251.9\;ng/ml$, and $T_{max}$ values were $3.42{\pm}1.43\;hr\;and\;1.96{\pm}1.23\;hr$, respectively. SRP tablets showed similar AUC values, but lower $C_{max}$ and longer $T_{max}$ values than PZQ. In the phase 2 study, SRP at 30 mg/kg (single dose) achieved a 60% cure rate and a 95.5% egg reduction rate. The cure rate of a single dose SRP was unsatisfactory compared with that of the conventional PZQ dose, but much better than that achieved by a single dose PZQ.

Background: The continuous epidural analgesia is a popular method in the management of postoperative pain. However, the exact regimen for the optimal analgesia is still in dispute. In this study, we evaluated the effect of an initial loading dose prior to the continuous epidural infusion after a brief surgery, which may have some residual effects of local anesthetics that is used for the intraoperative epidural anesthesia. Methods: Seventy five patients required epidural anesthesia with 15 ml of 2% mepivacaine for the perianal surgery were randomly divided into three groups: Group 1, being the control group (n=25) did not received postoperative epidural pain control. But, group 2 (n=25) and 3 (n=25) received continuous epidural analgesia with local anesthetics and morphine immediately after surgery. In Group 2, the patients received continuous epidural infusion without initial loading dose. In Group 3, the patients received initial loading dose (1% mepivacaine 6 ml and morphine 1 mg) and followed by continuous epidural infusion. We evaluated the number of patients who needed adjuvant analgesics, the pain score, and incidence of side effects for the postoperative 48 hours. Results: At postoperative 12 hours, in group 3, the two variables, the number of patients who needed analgesics and the pain score showed a statistical significance with low scores compared with group 1 and 2. At postoperative 24 and 48 hours, the two variables indicated above did not show any differences in group 2 and 3. The incidence of side effects is not different among the three groups. Conclusions: The loading dose prior to continuous epidural infusion is necessary after a brief surgery which may have some residual effects of local anesthetics that is used for the intraoperative epidural anesthesia.

The goal of this study is to review and define the role of nurses' who are engaged in Korea Oriental medical treatments in oriental medical hospitals. We think this study can contribute to the development of 'Korea Oriental medical science & nursing science' and 'Public health care'. A large portion of nurses's role in Korea Oriental Medicine(KOM. 한방/한의학) is assistance to doctors treatment. But besides of these role, we think there are many things that are riskless for nurses to do alone. But in present situation, few nurses in KOM. have enough knowledge to treat these medical treatments alone. So we believe this study will provide a way for nurses to participate more actively in KOM. public health care. With the goal of this study, we checked all medical treatments that have been practiced in oriental medical hospitals, and classified these treatments with some groups. And we organized a inquiry. At this inquiry, we ask 'What is the adequate role of nurses in Korea Oriental medical treatment? & What kind of treatment can nurses do?' We got 58 responses from nationwide 121 hospitals. From these response, more than half of them said nurses can do following medical treatment in the oriental medical hospital: 1. starting and ending part of following treatments; External treatments by instrument, by hydrotheraphy, by herb, by suction, moxibustion, Manipulative therapies on soft structure, Living and mind-body therapies. 2. pulling out Acupuncture. 3. boiling herb, judgement on dosing temperature, assisting in dosing, 4. assisting Diet, 5. operating from Living and mind-body therapies. 6. leading Physical training However, these results are coming out from present situation. So, after well-oriented instructions for nurses, this study will be need to carry out again. From this study, we suggest a desirable curriculum for students who study 'Korea Oriental Nursing Science.' That is to say, at basic course students take 4 subject for 6 credits. And at as an expert course, it should be dividend into Clinical Nursing Specialist in KOM., Self-care Nursing Specialist, Regimen Nursing Specialist and take 17 credits per each course.

Objectives : The effects of Jaeumkanghwatang (JEKHT) co-administration on the pharmacokinetics of tamoxifen were observed after oral combination treatment of tamoxifen 50 mg/kg with JEKHT 100 mg/kg on JEKHT 6-day repeated oral pretreated rats with 8-day repeated co-administration to confirm the effects of JEKHT co-administration on the pharmacokinetics of tamoxifen. Methods : Six days after pretreatment of JEKHT 100 mg/kg, tamoxifen 50 mg/kg was co-administered with JEKHT 100 mg/kg, once a day for 8 days within 5 min. The blood were collected at 30 min before administration, 30 min, 1, 2, 3, 4, 6, 8 and 24 hrs after end of first and last 8th tamoxifen treatment, and plasma concentrations of tamoxifen were analyzed using LC-MS/MS methods. PK parameters of tamoxifen ($T_{max}$, $C_{max}$, AUC, $t_{1/2}$ and $MRT_{inf}$) were analysis as compared with tamoxifen single administered. Results : Six-day repeated oral pretreatment of JEKHT and 8-day repeated oral co-administration of tamoxifen within 5 min did not influenced on the plasma concentrations and pharmacokinetic parameters of tamoxifen, oral bioavailability, as compared with tamoxifen single treated rats, except for some negligible effects. Conclusions : It is concluded that JEKHT did not influenced on the plasma concentrations and pharmacokinetic parameters, the oral bioavailability of tamoxifen. Therefore, it is considered that co-administration of JEKHT and tamoxifen will be provide an effective novel treatment regimen on the comprehensive and integrative medicine for breast cancer patients, if they showed favorable synergic effects on the pharmacodynamics or reduce the tamoxifen treatment related toxicity and side effects in future studies.

Obesity in children is a major concern of public health. This study was performed to illuminate its effect on weight control program and the associated factors of obesity-related habits and obesity index in primary school obese children. Weight control program consisted of behavioral modification, nutrition education and exercise during 17 weeks. The sample consisted of treatment group(n=42) and control group(n=41). There was no statistical difference between the two groups in obesity index, socioeconomic status and grade. To assess the effects of weight control program, the subjects were given pre-test and post-test such as the measurement of anthropometric values and self-reporting questionnaire. This result of this study were as follows; 1. After weight control program was applied, there was a significant decrease in obesity index among the treatment group. Obesity-related habits score of the treatment group increased significantly, While there was not much difference between the pre-test and the post-test among the control group. But exercise habit didn't increase significantly in the both groups. 2. Correlation between obesity-related habits and obesity index were not evident. 3. After application of weight control program, the factors associated with change of eating habit were children's past experience of weight control, motivational change toward weight control program and friends' support for treatment group. The factors associated with change of exercise habit were post-test motivation score and friends' support. Motivational change toward weight control and pre-test self-efficacy of exercise behavior were counter-related to exercise habit. For change of other obesity-related habits, initial obesity index, motivational change, post-test self-efficacy score of exercise behavior and paternal educational status were closely associated. But post-test self-efficacy score of eating behavior was unrelated. 4. Only the factor of experience of weight control was associated with change of obesity index. 5. For the both groups, the factors associated with change of eating habits were post-test self-efficacy of eating behavior and family's support. The factors associated with change of exercise behavior were self-efficacy changes of exercise behavior and friends' support. The factors associated with change of other obesity-related habits were self-efficacy change of eating behavior. Initial obesity index was associated with change of obesity index. 6. The rate of dropouts from weight control program was 28.6% (12/42) in treatment group. Initial obesity index, other obesity-related habits except eating exercise habits, friend's support were associated with dropout. In conclusion, these results indicated that weight control program in primary school settings was effective. Direct exercise regimen and practice was demanded. In addition to the program itself, much of the success is dependent on the degree of motivation of the children involved and support provided by their parents and friends. Further study need to be performed under the condition that the weight control progrom is applied for a longer period.

Background: Opioid delivered by epidural patient-controlled analgesia (PCA) is effective in relieving pain after surgery, but it is associated with side effects, such as nausea, vomiting, pruritus, respiratory depression, and urinary retention. The purpose of this study was to compare hydromorphone related side effects and the quality of analgesia when naloxone was added to epidural PCA regimen. Methods: Fifty-two thoracotomy patients with PCA were allocated blindly into two groups. Patients in group H (n = 26) received continuous epidural hydromorphone ($16{\mu}g/ml$) in 0.1% bupivacaine; patients in group N (n = 26) received an epidural infusion containing naloxone ($2{\mu}g/ml$) and hydromorphone ($16{\mu}g/ml$) in 0.1% bupivacaine. The basal rate of PCA was 4 ml/hr and the demand dose was 1.5 ml with a lockout time of 15 min. Pain intensity, sedation, pruritus, nausea and vomiting, respiratory depression were checked at 6, 12, 24 hours postoperatively. Results: The Visual Analog Scale (VAS) scores were significantly lower in group H than in group N. There were no significant differences in the overall incidence of pruritus, nausea and sedation between the two groups. Conclusions: Continuous epidural infusion of naloxone combined with hydromorpho-ne is not effective in reducing the incidence and severity of pruritus induced by epidural hydromorphone.

Objective: The role of chemotherapy in locally advanced head and neck cancer has been established in nasopharynx and larynx as definitive therapy and organ preserving therapy, respectively. Oral cavity cancers are relatively uncommon and local recurrence is the main cause of treatment failure. We planned this retrospective study to evaluate the role of neoadjuvant chemotherapy in locally advanced oral cavity cancer patients. Materials and Methods: From 1988 March to 2001 February, locally advanced, previously untreated oral cavity cancer patients who received neoadjuvant chemotherapy were examined. Chemotherapy had been done in the following patients: Histologically proven squamous cell or poorly differentiated carcinoma, stage 3 or 4, and performance state 0-2 patients. Chemotherapy regimen consisted of cisplatin and infusional 5-fluorouracil. Response was evaluated after 2 cycles and in case of no response, definitive local therapy was done; otherwise 3 cycles was done before local treatment. Results: 48 patients were treated and 47 patients were evaluable for responses. Complete response rate was 6.4%(3/47) and partial response 80.0%(38/47), scoring overall response rate of 87.2%. Median time to progression was 27.0 months (95% CI : 0-58months) and overall 5 year survival was 54.8%. 5-year disease-free survival in the patients in remission after local treatment was 51.9%. In multivariate analysis, contributing factor to the survival were response to neoadjuvant chemotherapy and local treatment modalities. Extensive surgery was done in 10 patients and 25 patents (52.1%) was followed up with preserved function. With median follow-up of 57.0 months, 19 recurrences were detected, most of which were local or regional type. Conclusion: Neoadjuvant chemotherapy followed by local treatment in oral cavity cancer showed high response rate and was thought to be effective therapeutic approach especially in view of organ preservation.

증식성 기관지염(plastic bronchitis)은 드문 질환으로 일반적인 점액전에 비해 크고 접착력이 있는 가지모양의 점액성 기관지 주형(cast)을 반복적으로 형성한다. 이 주형은 크기가 다양하여 자연적으로 배출되기도 하나 제거를 위해 기관지경이 필요하기도 한다. 따라서 증식성 기관지염에서 큰 기도의 폐쇄가 발생하면 생명을 위협할 수 있다. 호산구성 주형을 가진 보고된 환자 22명 중 3명이 중심 기도 폐쇄로 인해 사망에 이르렀다. 본 저자들은 아토피나 알레르기, 선천성 심장병의 병력이 없는 건강했던 소아에서 호산구성 증식성 기관지염을 진단하여 보고한다. 항생제와 스테로이드의 정주와 물리 치료를 포함한 적극적인 폐 청소와 주기적인 주형의 기관지경 제거를 시행하였으나 저산소성 뇌 손상에 이어 뇌사에 이르렀다. 본 증례와 같이 증식성 기관지염이 중심 기도를 막았을 때 생명을 위협할 수 있다. 따라서 증식성 기관지염의 증상이나 징후가 보일 경우 조기 치료가 필요하리라 생각된다.

Purpose: Childhood obesity is an increasing public health issue worldwide. We examined dietary patterns among adolescents in a dormitory school, identified obese adolescents and tried to intervene to improve food habits and physical activity. Methods: We conducted an experimental prospective longitudinal study based on 36 obese (body mass index $[BMI]{\geq}95th$ percentile) adolescents (aged 12-18 years) compared with controls (healthy children: normal age-appropriate BMI ($BMI{\leq}85th$ percentile). Six months' intervention included lifestyle-modification counseling (once a week by a clinical dietician), and an exercise regimen twice a week, 60 minutes each time, instructed by a professional pediatric trainer). Both groups underwent baseline measurements at the beginning of the study and 6 months later (arterial stiffness, blood pressure, pulse, weight and height, hemoglobin, creatinine, liver enzymes, highly sensitive C-reactive protein and complete lipid profile). Results: Twenty-one participants completed the study. Low compliance from participants, school staff and parents was observed (participation in planned meetings; 71%-83%). BMI significantly decreased from $32.46{\pm}3.93kg/m^2$ to $30.32{\pm}3.4kg/m^2$ (P=0.002) in the study group. Arterial stiffness was not significantly different between the 2 groups and did not change significantly after 6 months' intervention (P=0.494). No significant changes in CRP and lipid profile were observed after the intervention. Conclusion: Making lifestyle modifications among adolescents in a dormitory school is a complex task. Active intervention indeed ameliorates BMI parameters. However, in order to maximize the beneficial effects, a multidisciplinary well-trained team is needed, with emphasis on integrating parents and the school environment.
