This study aimed to evaluate the effect of dietary fiber supplementation with snack type on functional constipation. We conducted a double blind case-control study with 3 groups; placebo, low dose group (LD: insoluble fiber 7 g/d + soluble fiber 1.2 g/d) and high dose group (HD: insoluble fiber 14 g/d + soluble fiber 2.4 g/d) , which were randomly assigned out of subjects with functional constipation, defined by modified Rome II criteria. We measured anthropometric parameters and evaluated the bowel movement frequency, stool type, straining, sense of complete evacuation, abdominal discomfort/pain, abdominal inflation, relief and colon transit time before, during the supplementation. Both LD and HD groups had significant improvement in straining, sense of complete evacuation and satisfactory relief compared with placebo group (p < 0.05). When subdivide by baseline colon transit time (less than 24 hrs/ 24 hrs or more and less than 72 hrs / 72 hrs or more), only HD group had significantly improvement; colon transit time recovered near by 24 hrs in subjects of 'less than 24 hrs' (from $7.57{\pm}1.40$ hrs to $25.2{\pm}3.91$ hrs, p < 0.01) and reduced in those of '24hr or more and less than 72 hr' (from $47.0{\pm}3.36$ hrs to $31.3{\pm}4.31$ hrs, p < 0.01) and '72 hr or more' (from $106.7{\pm}10.7$ hrs to $85.0{\pm}13.1$ hrs, P < 0.05) subjects. Particularly, positive effect of fiber supplementation on straining and sense of complete evacuation in test groups seemed to be greater in subjects of '24 hrs or less' and '24 hrs or more and less' than 72 hrs' than those of '72 hrs or more'. In conclusion, subjects with functional constipation, particularly those having colon transit time less than 72 hrs can significantly improve, at least in part, symptom related to constipation by fiber supplementation of snack type without serious side effects.

Purpose: Tumor bleeding is a major complication in inoperable gastric cancer. The study aim was to investigate the effects of proton pump inhibitor (PPI) treatment for the prevention of gastric tumor bleeding. Materials and Methods: This study was a prospective double-blind, randomized, placebo-controlled trial. Patients with inoperable gastric cancer were randomly assigned to receive oral lansoprazole (30 mg) or placebo daily. The primary endpoint was the occurrence of tumor bleeding, and the secondary endpoints were transfusion requirement and overall survival (OS). Results: This study initially planned to enroll 394 patients, but prematurely ended due to low recruitment rate. Overall, 127 patients were included in the analyses: 64 in the lansoprazole group and 63 in the placebo group. During the median follow-up of 6.4 months, tumor bleeding rates were 7.8% and 9.5%, in the lansoprazole and placebo groups, respectively, with the cumulative bleeding incidence not statistically different between the groups (P=0.515, Gray's test). However, during the initial 4 months, 4 placebo-treated patients developed tumor bleeding, whereas there were no bleeding events in the lansoprazole-treated patients (P=0.041, Gray's test). There was no difference in the proportion of patients who required transfusion between the groups. The OS between the lansoprazole (11.7 months) and the placebo (11.0 months) groups was not statistically different (P=0.610). Study drug-related serious adverse event or bleeding-related death did not occur. Conclusions: Treating patients with inoperable gastric cancer with lansoprazole did not significantly reduce the incidence of tumor bleeding. However, further studies are needed to evaluate whether lansoprazole can prevent tumor bleeding during earlier phases of chemotherapy (ClinicalTrial.gov, identifier No. NCT02150447).

Objectives : The purpose of this study was to report possibility of acupuncture or moxibustion for the treatment of Parkinson's disease (PD) by reviewing literature about its effectiveness. Methods : In this review, PubMed, SCOPUS, Science Direct and CINAHL of EBSCOhost were used to search medical journals, using keywords "Parkinson's disease and acupuncture" and "Parkinson's disease and moxibustion". The search range included randomized controlled trials (RCT) about Parkinson's disease combined with another disease and other treatments with acupuncture or moxibustion. Non-randomized controlled trial (nRCT), case study, animal experiment, human experiment, review, survey, essay, letter, and protocol for review were excluded. Results : From 311 studies, 111 were selected during the title and the screening. Finally, 16 RCTs (15 for acupuncture research and one for moxibustion) were included in this review, after scanning and matching the inclusion and exclusion criteria. The number of patients varied between 5 and 88. A total of 12 studies using electroacupuncture (EA) were classified into acupuncture studies. The body acupuncture studies numbered 4, scalp acupuncture 4, body and scarp acupuncture mixed studies 4, and bee venom, ear and abdomen acupuncture were each one study. In evaluation methods, total effective rate method was used in 9 studies, the Unified Parkinson's Disease Rating Scale (UPDRS) was used in 8, and the Webster score in 2. In addition, the Berg balance scale (BBS), 30 m walking time, steps to walk 30 m, PD motor function score, and Motor Performance Series by Schoppe (MLS) method were used for evaluation. In 15 of the 16 studies, the verum acupuncture group showed significant improvement compared with the control. In 9 studies using total effective rate method, the effective rate was reported as 80.0-97.3% in verum acupuncture groups and 52.6-86.4% in controls. Conclusions : Acupuncture may be a plausible alternative method to care for the long term symptoms and treat movement impairment of Parkinson's disease. However, to confirm this result, high quality studies including randomized, placebo-controlled double-blind trials are warranted.

배 경 : Gemifloxacin은 그람음성 및 그람양성 균주에 대해서 모두 좋은 활성을 가지고 있는 fluoroquinolone 항균제로서, 임상균주를 이용한 in vitro 시험에서 다른 대조 quinolone에 비하여 S. pneumnoniae의 penicillin 내성 균주에 대해서 활성이 높을 뿐만 아니라, 다른 quinolone 항균제에 내성을 나타내는 S. pneumoniae 임상 균주에 대해서도 좋은 활성을 유지하는 것으로 밝혀져 만성기관지염의 급성악화(AECB)시 사용하기 적절한 치료제로 여겨진다. 목 적 : 한국인에서 AECB를 치료하기 위한 LB20304(gemifloxacin) 160mg 또는 320rng 1일 1회 7일간 투여의 유효성과 안전성을 평가하고자 하였다. 방 법 : Gemifloxacin 100mg과 위약을 1일 1회 7일간 경구 투여한 환자 67명, gemifloxacin 320mg을 1일 1회 7일간 경구 투여한 환자 70명의 환자를 대상으로 무작위 배정, 이중맹검, 병행 치료군, 다기관, 2상 임상시험으로 실시하였다. 결 과 : 두 치료군의 인구통계학적 특징과 임상적 및 흡연 기왕력 등 기저 상태는 대등하였다. Per-protocol(PP) 환자군에서, 추적관찰 시점(days 14-21) 및 치료종료 시점(days 7-10)에서의 임상적 반응은 gemifloxacin 100mg군이 각각 84.2%, 96.5%, 320mg군이 각각88.7%, 96.4%로 두 군간에 유의한 사이가 없었고(각각 p=0.49, p=0.99), 추적관찰 시점 및 치료종료 시점의 미생물학적 반응도 gemifloxacin 160mg군이 각각 78.9%, 81.8%, 320mg군이 각각 84.2%, 86.4%로 두 군간에 유의한 차이가 없었다(각각 p=0.68, p=0.68) 본 임상시험에서 치료 전에 많이 배양된 병원균으로는 S. pneumoniae(12/52), H. influenzae(10/52), K. pneumoniae(6/52), M. catarrhalis(3/52) 로 K. pneumoniae가 비교적 많이 배양된 점을 제외하고는 기존에 알려진 AECB 시 배양되는 병원균의 분포와 큰 차이가 없었다. S. pneumoniae, H. influenzae, K. pneumoniae, M. catarrhalis 등 주요 병원 균에 대한 MIC는 전반적으로 다른 quinolone 항균제보다 gemifloxacin이 더 낮았고, 특히 S. pneumoniae(3 PRSP, 7 ERSP 포함)에 대한 gemifloxacin의 MIC(${\leq}0.03ug/ml$)는 다른 quinolone, beta-lactam, macrolide 항균제보다 월등히 낮아 gemifloxacin 이 AECB의 치료에 매우 유용한 항균제임을 보여주었다. 안전성 결과에서는 gemifloxacin 160mg 및 320mg 투여군 모두 시험약과의 관련성을 배제할 수 없거나 관련이 의심되는 중대한 이상반용은 관찰되지 않았고, 치료 중 및 치료 후 30일 기간동안, 이상반응을 최소한 하나 이상 보고한 환자가 gemifloxacin 160mg군은 26.9%, 320mg군은 31.4%이었다. 가장 흔히 보고된 이상반응은 간효소 수치의 증가로서, 발생 빈도는 160mg군에서 1/67명(1.5%), 320mg군에서 5/70명(7.1%) 이었다. 간효소 수치의 증가로 인해 탈락한 환자는 없었고, 중증도(severity)는 모두 경도(mild)였으며, 별다른 처치 없이 정상으로 회복되었다. 전반적인 이상반응의 profile에서 치료군간 주요한 차이는 없었다. 결 론 : 본 임상시험의 결과, 한국인에서 AECB를 치료하기 위한 gemifloxacin 160mg 또는 320mg 1일 1회 7일간의 투여는 임상적 및 미생물학적으로 매우 유효하고 안전하였다.

Purpose: This study examined the effects of curl-up using XCO^® on trunk muscle activation in healthy adults. Methods: This study design was a single-blind randomized controlled trial. Twelve participants were enrolled in this study. The subjects were instructed to perform curl-up exercise in STCU (straight curl-up), LTCU (left twist curl-up), RTCU (right twist curl-up), TWCU (twist curl-up), and PPCU (power push curl-up). Electromyography was used to assess the percent maximal voluntary isometric contraction (%MVIC) of the rectus abdominis (RA), external oblique (EO), internal oblique (IO), and erector spinae (ES) muscles. The data were analyzed using two-way ANOVA with a repeated measure. The statistical significance level was set to α=0.05 Results: The IO showed significant differences in the main effect of the group and the interactions between the group and exercise (p<0.05). In particular, the IO represented the interactions between group and exercise in the RTCU and PPCU (p<0.05). The RA, EO, and ES did not show significant interactions between the group and exercise (p>0.05). The RA, IO, and EO showed significant differences in the main effect of the group (p<0.05). The EO showed a significant difference in the main effect of exercise (p<0.05). Conclusion: These findings suggest that XCO^® can be used to increase the muscle activation of the internal oblique, which is the lumbar stabilizing muscle, when XCO^® is combined in the curl-up exercise with rotation. In the future, research on the intensity, frequency, and duration of XCO^® exercise will be needed according to the individual characteristics and preferences.

Objectives: The present study evaluated the effects of sa-am acupuncture (SAA) simpo-jeongkyeok (SPJK) treatment on the blood pressure (BP), pulse rate (PR), and body temperature (BT) of patients with hwa byung (HB). Methods: This patient assessor blind, randomized, placebo controlled trial included 50 volunteers, divided randomly into two groups. The treatment group underwent SPJK (PC9, LR1, PC3, KI10) while the control (sham) group received minimal needle insertion at non acupoints. The BP in both arms, PR, and BT at several acupoints were measured before and after treatment at the $1^{st}$, $2^{nd}$, $3^{rd}$, and $4^{th}$ visits and before treatment at the follow-up visit. We analyzed data by using the repeated measured analysis of variance (RM ANOVA), Mann-Whitney U, and wilcoxon signed rank tests; differences at P < 0.05 were considered significant. Results: No significant differences in the systolic blood pressure (SBP), diastolic blood pressure (DBP) and PR between the treatment and control group were observed at each visit. However, the decrease in the SBP for the treatment group before and after each visit was significantly higher than it was in the control group. The SBP in both arms in the treatment group was decreased between visits 1 and 2, 1 and 3, 1 and 4, and 1 and follow-up. The DBP in both arms and in the right arm between visits 1 and 3 in the treatment group showed decreases. A minimal BT increase for treatment at CV06 and CV12 and a minimal BT decrease for treatment at CV17 and (Ex) Yintang were found. Patients in the treatment group who visited more frequently experienced a greater decrease in the PR, but that effect was not maintained. Conclusion: The results suggest that SAA SPJK treatment has instant positive effects on the BP, PR, and BT in patients with HB, but the effects on the BP and PR are not maintained.

Background: The purpose of this study is to investigate the effect of wall squat exercise according to the difference in the support surface on the thickness change of external oblique, internal oblique and transverse abdominalis of the trunk muscles and the change in distance of center of pressure when the eyes are opened and closed. Design: Randomized controlled trial. Methods: The subjects were 26 healthy adults, 18 males and 8 females. The composition of each group using the single-blind method was 13 people in the unstable side wall squat exercise group and 13 people in the stable side wall squat exercise group. Experimental measurements were divided into before, 3 weeks, and 6 weeks after the experiment, and changes in muscle thickness and balance were confirmed. Muscle thickness was measured using ultrasinic, and static balance change was measured using Bio-rescue. Results: There were significant differences in the thickness changes of external oblique, internal oblique and transverse abdominalis according to the wall squat exercise method by period and in the interaction between the period and the group (p<0.05). As a result of the post-hoc analysis, there was a significant difference in the change between the two groups in external oblique muscle after 6 weeks. And there was a significant difference in the distance of the pressure center between eyes open and closed eyes (p<0.05). Conclusion: In terms of instability, wall squat exercise was positive for changes in trunk muscle thickness. It suggests the possibility of using it for trunk muscle strengthening training in the future.

Objectives: The purpose of this study is to explore the effectiveness and safety of frequently used clinical herbal medicines (Yijung-tang [Lizhong-tang, LJT], Pyeongwi-san [Pingwei-san, PWS], and Shihosogan-tang [Chaihu Shugan-tang, SST]) in patients with functional dyspepsia (FD) when administered according to herbal medicine and Korean medicine pattern identification. The results of this study will be used to standardize the diagnostic instrument used in Korean medicine and to investigate biomarkers of Korean medicine pattern identification. Methods: This study will be a randomized, assessor-blind, 3-arm, parallel, open-label, multi-center clinical trial. A total of 300 FD participants will be recruited from 3 Korean medical hospitals and assigned to the LJT (n=100), PWS (n=100), and SST (n=100) groups according to FD pattern identification. The patients will take the medication for 8 weeks, 3 times a day, before or between meals. The primary outcome will be total dyspepsia symptom (TDS) and the secondary outcomes will be adequate relief (AR) for dyspepsia, overall treatment effect (OTE), visual analogue scale (VAS), functional dyspepsia-related quality of life (FD-QoL), gastrointestinal symptom score (GIS), and pattern identification questionnaires. For the exploratory outcomes, we will analyze blood and fecal metabolome profiles, microbiota from fecal and saliva samples, single nucleotide polymorphism (SNP), and results of Korean medicine diagnosis device measurements (heart rate variability, and tongue, pulse, and abdominal diagnosis). Conclusions: The results of this study will prove objectivity for Korean medicine pattern identifications, and the effectiveness and safety of herbal medicines for the population with FD.
