Purpose: This report aims to administer methodologic issues around recently conducted multicenter study for evaluating the effects of acupuncture on menopusal hot flashes and discuss practical issues for further implementation of acupuncture clinical trial for hot flashes. Methods: Study process were mentioned, and issues related to avoiding risk of bias, designing appropriate control group, optimal outcome measurement, potential different effects of menopausal status on study outcomes, and suggestions for developing future clinical trials are discussed. Results: Shortcomings of our multicenter study include lack of allocation concealment and assessor blinding, subjective outcome measurement, short-term follow-up, and fixed acupuncture regimen despite pragmatic purpose of this study. Improving trial design, using objective or validated outcomes, assessing long-term effects of acupuncture, and individualizing acupuncture regimen are needed in future clinical trials. Conclusion: We expect these practical discussions to enable researchers to plan and develop future well-designed clinical trials for evaluating the effects of acupuncture on hot flashes or other women's health issues.

A study was carried out to assess the therapeutic effect of ascorbic acid in mastitis of dairy cows. The herd with a population of 250-275 lactating cows was screened for clinical and subclinical mastitis for a period of 5 months. Based on inclusion and exclusion criteria, eighteen animals each with clinical and subclinical mastitis in one quarter only were selected as study population. Twelve cows (group A) with normal udder and health were also selected as a healthy control. Clinical mastitis cows were grouped as B (n=12) and C (n=6). Cows of group B were treated with ascorbic acid at 25 mg/kg, subcutaneously for 5 consecutive days and intramammary infusion (Ampicillin sodium 75 mg and Cloxacillin sodium 200 mg/infusion) based on antibiotic sensitivity test, till complete recovery. Group C cows received only intramammary infusion till the complete recovery. Eighteen subclinical mastitis cows were divided in group D (n=12) and E (n=6). Cows of group D were treated with ascorbic acid at 25 mg/kg subcutaneously for 5 consecutive days while group E did not receive any treatment. California mastitis test (CMT), somatic cell count (SCC), physical changes of udder and milk were used to diagnose and classify the mastitis. Evaluation of the therapy was based on CMT score and physical changes of udder and milk. Sample size calculation was also performed but was not followed for control groups due to scarcity of cases. Adequate blinding was done when and where required to avoid the biases. Confounding variables like herd, age of the cow, stage of the lactation, season and geographical region were duly considered and adequate blocking was followed. Ascorbic acid was administered in clinical and subclinical cases even after cure considering its immunostimulatory and healing inducing effects. The recovery rate was faster in cases of clinical mastitis treated with ascorbic acid along with an intramammary infusion (group B) than the quarters of group C cows. Quarter wise the average duration/number (3.16${\pm}$0.11 days) of antimicrobial intramammary infusion was significantly (p<0.01) less in group B than that of average duration/number (5.33${\pm}$0.20 days) of group C. Subclinical mastitis cows treated with ascorbic acid showed 83.33% recovery while 16.77% did not respond to treatment till last day of study. Cows of group E (untreated) did not recovered from the mastitis. Subjective parameters viz. swelling, pain reflex of udder and physical changes in milk from quarter of ascorbic acid treated cows (group B) disappeared earlier than that of group C cows. It is concluded from this study that the ascorbic acid might be useful as an adjunct in case of clinical mastitis to get quick recovery with less number of intramammary infusions. High recovery rate in subclinical mastitis quarters of group D cows is appreciable and opens a new avenue to conduct further trials in a larger population in various field conditions. However, the pharmacology of ascorbic acid with particular reference to health of mammary gland needs to be investigated.

Objectives: This study aimed to confirm the optimal processing conditions of the asbestos stabilizer by considering various actual environments at the time of stabilization treatment of the ceiling materials containing asbestos with asbestos stabilizer. Methods: The anti-scattering performances of the asbestos stabilizer were confirmed by considering the method and quantity of the asbestos stabilizer treated, comparing the loss weight by measuring the weight of ceiling materials prior to and after having treated 30, 50, 100, 200, and 400 of stabilizer using the brush and spray. The effects of backside dust and steel frame structure on the performances of the stabilizer was also confirmed by comparing samples with and without the dust on the rear surface removed by wiping the ceiling material specimens and the blinding treatment simulated by using tape. Results: The asbestos stabilization treatment using the brush method in comparison with the use of a spray has reduced stabilizer loss, resulting in better anti-scattering performance. In addition, the stabilizer loss is increased with increasing treatment quantity; as a result, treating a larger quantity of stabilizer does not improve the performance. For the conditions related to ceiling materials, the anti-scattering performance is enhanced by removing the backside dust and spreading the stabilizer evenly on the masking portion by steel frame structures. Conclusions: Based on these results, it is determined that the appropriate choice of the tool used for the treatment of the asbestos stabilizer and the appropriate quantity of asbestos stabilizer were needed at the time of actual stabilization processing of the ceiling materials containing asbestos. Moreover, this study confirmed that preliminary processing and verification of the structure at which the ceiling materials are installed can enhance the effectiveness of prevention of the scattering of asbestos into the air.

Objectives : To address most probable and suitable method for designing clinical trial intervening Traditional Korean Herbal Medicine on hwa-byung. Study Design : A systematic review of research studies of complementary and/or alternative medical(CAM) treatment of depression, and of domestic clinical trials of Traditional Korean Medicine, and of Chinese clinical trials of Traditional Chinese Medicine. Methods : Randomized, controlled trials(RCTs) of treatment of depression intervening herbal medicine were searched through MEDLINE, Cochrane Library, and CNKI databases. Also, domestic RCTs intervening Traditional Korean Herbal Medicine were searched through Korean Traditional Knowledge Portal and Korean studies Information Service System(KISS). Studies were evaluated using Iadad scale and self-designed tool for this study. Results : Thirty four RCT studies( 10 from MEDLINE, 16 from CNKI, 8 domestic studies) of herbal medicine met inclusion criteria. Mean Jadad score of studies published in English was 2.8${\pm}$0.79, in Chinese 1.94${\pm}$0.77, and in Korean 2.75${\pm}$0.71. Twenty one percent of studies included pattern differentiation in their inclusion criteria. Twenty nine percent of studies used combined treatment of herbal and conventional medicine. Among studies on depression, 9% included Complementary Medical assessing tools. Conclusions : There is shortage of domestic clinical trial involving herbal medicine. In China, studies tend to focus on investigating effect of Combined treatment of herbal and conventional medicine on depression. Clinical trial(s) of hwa-byung should provide good internal validity by describing methodology for randomization, double-blinding, and attrition. Also, specific guideline for clinical trial, including Traditional Korean Medical aspects across inclusion criteria, and assessing tools is needed.

Objective: Computed tomography enterography (CTE) and magnetic resonance enterography (MRE) are considered substitutes for each other for evaluating Crohn's disease (CD). However, the adequacy of mixing them for routine periodic follow-up for CD has not been established. This study aimed to compare MRE alone with the mixed use of CTE and MRE for the periodic follow-up of small bowel inflammation in patients with CD. Materials and Methods: We retrospectively compared two non-randomized groups, each comprising 96 patients with CD. One group underwent CTE and MRE (MRE followed by CTE or vice versa) for the follow-up of CD (interval, 13-27 months [median, 22 months]), and the other group underwent MRE alone (interval, 15-26 months [median, 21 months]). However, these two groups were similar in clinical characteristics. Three independent readers from three different institutions determined whether inflammation had decreased, remained unchanged, or increased within the entire small bowel and the terminal ileum based on sequential enterography of the patients after appropriate blinding. We compared the two groups for inter-reader agreement and accuracy (terminal ileum only) using endoscopy as the reference standard for enterographic interpretation. Results: The inter-reader agreement was greater in the MRE alone group for the entire small bowel (intraclass correlation coefficient [ICC]: 0.683 vs. 0.473; p = 0.005) and the terminal ileum (ICC: 0.656 vs. 0.490; p = 0.030). The interpretation accuracy was higher in the MRE alone group without statistical significance (70.9%-74.5% vs. 57.9%-64.9% in individual readers; adjusted odds ratio = 3.21; p = 0.077). Conclusion: The mixed use of CTE and MRE was inferior to MRE alone in terms of inter-reader reliability and could probably be less accurate than MRE alone for routine monitoring of small bowel inflammation in patients with CD. Therefore, the consistent use of MRE is favored for this purpose.

게이트 심근관류 SPECT의 정량적 평가를 위해 사용되는 자동화된 정량화 소프트웨어(AutoQUANT)는 획득 자료 처리과정에 따라 측정치 오차가 발생할 것으로 예상된다. 동일한 환자를 대상으로 다른 조건의 변화 없이 QPS (Quantitative Perfusion SPECT) 프로그램에서 Myocardial extract 전후에 따른 정량적 지표를 구하여 평가하고자 한다. 2010년 6월부터 2010년 12월까지 부산대학교병원 핵의학과에서 Tc-99m MIBI 게이트 심근관류 SPECT를 시행한 환자 중 51명(남:여=34:17, 평균나이 $66.45{\pm}9.92$)을 대상으로 하였다. 심근의 단축단면상을 이용하여 원형 관심영역은 배후영역을 제외한 심근영역에서 설정한 자료를 획득하였다. AutoQUANT를 이용한 QPS 프로그램에서 일과성허혈확장(Transient Ischemic Dilation, TID), 부하기 관류결손 범위율의 합(Extent of Stress Defect, ESD)과 부하기 관류점수 합(Summed Stress Score, SSS)을 구하여 비교 분석하였다. QPS 프로그램에서 Myocardial extract 적용 전과 적용 후 정량적 지표의 상관계수는 TID (r=0.98), ESD (r=0.99), SSS (r=0.99) 모두 좋은 상관관계를 보였다. 95% 신뢰수준에서 TID (p=0.78), ESD (p=0.31), SSS (p=0.19) 모두 통계적으로 유의한 차이가 없었다. 육안분석에서는 판독에 영향을 줄 수 있을 만한 영상의 차이는 발견할 수 없었다. QPS 프로그램에서 Myocardial extract 적용 전과 적용 후 정량적 지표(TID, ESD, SSS)는 모두 좋은 상관관계가 있다는 것을 확인할 수 있었고, 통계적으로 유의한 차이를 보이지 않았다. Myocardial extract 영상처리기법이 비교적 간단하여 심근관류 SPECT 영상의 질을 올릴 수 있을 것으로 사료된다.

환자 피폭선량 관리에 입사표면선량(ESD, entrance surface dose)이 국내외적으로 진단참고준위(국내 흉부촬영 $340{\mu}Gy$)로 사용되고 있지만, ESD측정을 위해서는 선량계가 필요하다. 하지만 대부분 병의원에서는 선량계가 구비되어 있지 않고 정기검사 시 전문 업체 측정에 의해 확인할 수 있다. 따라서 본 연구에서는 흉부 디지털촬영에서 사용자가 쉽게 ESD를 예측할 수 있는 방법에 대해 알아보았다. 흉부 디지털촬영에서 평판형 디텍터(FP, Flat-panel detector)와 IP (Imaging plate detector)를 대상으로 하였고, ESD는 선량계(XI-Platinum, Unfors, Sweden)를 흉부 팬텀(07-646 Duke QC chest phantom, Supertech, Elkhart, USA)의 중앙 표면에 부착시킨 후, 튜브와 디텍터를 180cm 거리를 유지시켜 각 노출조건 조합(관전압과 노출선량)에서 3회 반복측정한 후 평균값을 얻었다. 흉부 팬텀 영상의 다이콤 헤더 정보에서 FP영상은 선량면적곱(DAP, dose-area product)을 확인하였고, IP영상에서는 노출 지수(EI, exposure index)를 확인하였다. 단순선형회귀분석을 통해 FP촬영에서 DAP로부터, IP촬영에서 EI로부터 ESD를 예측할 수 있는 회귀방정식($y={\alpha}+{\beta}X$, ${\alpha}$=직선의 절편, ${\beta}$=직선의 기울기)을 구하였다. FP가 IP 보다 유의하게 낮은 선량을 보였고($85.7{\mu}Gy$ vs. $124.6{\mu}Gy$, p=0.017), 두 디텍터 모두 ESD와 화질 간에 높은 양의 상관성을 보였다. FP에서 수정된 R 제곱(adjusted R2)은 0.978로 ESD의 변동은 DAP 변동에 의해 97.8%의 높은 설명력을 보였다. 단순 회귀식은 $ESD=0.407+68.810{\times}DAP$ 이었다. 위의 회귀식을 이용하여 국내 권고선량($340{\mu}Gy$)과 같은 DAP를 추정한 결과($DAP=0.021+0.014{\times}340{\mu}Gy$), DAP는 4.781 이었다. IP에서 수정된 R 제곱(adjusted R2)은 0.645로 ESD의 변동은 EI 변동에 의해 64.5%의 설명력을 보였다. 단순 회귀식은 $ESD=-63.339+0.188{\times}EI$ 이었다. 위의 회귀식을 이용하여 국내 권고선량($340{\mu}Gy$)과 같은 EI를 추정한 결과($EI=565.431+3.481{\times}340{\mu}Gy$), EI는 1748.97 이었다. 흉부 디지털 촬영에서는 팍스 워크스테이션 영상의 다이콤 헤더 정보에서 ESD를 사용자가 쉽게 예측할 수 있다.
