Objective. Productivity loss was compared by 3-stage of disease activity and associations between higher disease activity and high productivity loss were identified. Methods. Data were extracted from Rheumatoid Arthritis (RA) Patient-reported Outcomes Research, which enrolled 2,000 RA patients (>20-year) on disease-modifying-antirheumatic-drugs (DMARDs) (≥ 6-month) from December 2012 to June 2013. This included 1,457 RA patients with the disease activity score (DAS-28-ESR) in their medical charts. Productivity loss in time and indirect cost was estimated using The World Health Organization Health and Work Performance Questionnaire (HPQ). Baseline characteristics and productivity loss outcomes were compared according to DAS-28-ESR groups. Results. 84.4% were females, 54.2% had low DAS-28-ESR (<3.2), and 38.2% and 7.6% had moderate (3.2∼5.1) and high DAS-28-ESR (>5.1). Patients with moderate to high DAS-28-ESR had higher lost productivity time (LPT) and monthly costs of LPT than those with low DAS-28-ESR (time in hours: 110.0±58.4 vs. 132.4±57.2 vs. 71.5±52.0, p<0.0001; monthly costs of LPT in 1,000 Korean won: 1,097±607 vs. 1,302±554 vs. 741±531, p<0.0001). Multiple regression analyses revealed significant associations with high LPT in high (adjusted odds ratio [OR]=3.87, 95% confidence interval [CI]: 2.18∼6.87) and moderate DAS-28-ESR (adjusted OR=1.88, 95% CI: 1.41∼2.52) compared to low DAS-28-ESR. In addition, positive associations with high monthly costs of LPT were observed in high (adjusted OR=3.45, 95% CI: 1.98∼5.99) and moderate DAS-28-ESR (adjusted OR=1.93, 95% CI: 1.43∼2.54) compared to low DAS-28-ESR. Conclusion. Timely therapeutic strategies should be taken into consideration given that the RA patients with moderate to high DAS-28-ESR showed strong associations with high productivity loss for effective management of RA.

서성(Sung Seo),한대덕(Dae Duk Han),장선식(Sun Sik Jang),김원호(Won Ho Kim),정민웅(Min Woong Jung),최진혁(Jin Hyuck Choi),김진숙(Jin Sook Kim),김하영(Ha Young Kim),이종경(Joung Kyong Lee) 한국초지조사료학회 2012 한국초지조사료학회지 Vol.32 No.1

본 연구는 부존 조사료자원 이용으로 수입사료를 줄이고 사료비를 절감하고자 2010년도에 전남 해남(간척지), 강원 평창(강변), 원주(섬강변), 전남 영광(와탄강변) 등 4개 지역에서 갈대와 억새 등 야초 자생지를 탐색하고, 수확·이용실태 조사와 함께 사료가치를 분석하였다. 전남 해남 해남목장 내 갈대(Phragmites communis) 위주의 야초 자생지는 300 ha로 예년에는 2회 곤포작업하여 연간 사일리지로 2,300~2,500톤(ha당 8톤)을 생산하였으나 2010년도는 1회 곤포조제로 사일리지 2,000톤(ha당 7톤)을 생산하였다. 유통가격은 롤 당 53천원으로 ㎏당 110원이었다. 곤포는 전량 자가소비하며, 외부 작업단에 롤 당 26천원의 작업비를 지불하였다. 연간 조수입은 2억 2,260만원이며, 소득은 1억원 수준(345천원/ha)이었다. 초장 150 ㎝의 갈대는 조단백질 8.4%, 상대사료가치 71.9 (건초 5등급), 건물 소화율 60.1%로 사료가치는 볏짚에 비해 약간 나은 것으로 평가되었다. 갈대 사일리지의 사료가치와 유기산 함량은 동일 지역에서 동일한 재료로 사일리지를 조제하더라도 수확시기에 따라 차이가 컸으며(CP 4.7~6.4%, RFV 62.2~78.9, 건물 소화율 41.9~53.9%), 갈대 사일리지의 품질은 수단그라스에 비해 불량하였다. 강원 평창 강변 자생갈대의 사료가치는 초장이 79, 117, 121, 142㎝로 생육이 진행됨에 따라 낮아져, 조단백질은 각각 13.9%에서 7.6%로, 상대사료가치는 90.7 (건초 3등급)에서 76.1 (건초 4등급)로, 건물 소화율은 72.9%에서 54.7%로 감소하였다. 원주 섬강 주변 야초류는 곤포수확 작업에 어려움이 있었으며, 초장 130 cm의 갈대는 조단백질 8.5%, 상대사료가치 82.3 (건초 4등급), 건물 소화율 70.2%로 사료가치는 높았으며, 220㎝의 성숙한 갈대는 조단백질 10.2%, 상대사료가치 65.1 (건초 5등급), 건물 소화율 48.9%로 볏짚 대비 조금 나은 것으로 평가되었다. 전남영광지역에서는 와탄천 주변에 자생하는 갈대를 수거 이용하고자 시도하였으나 경제성이 없어 중단하였다. 이상의 결과를 종합하여볼 때, 갈대, 억새 등 야초류는 현 상태에서 최대한 수거·이용하되, 사료가치를 유지하고 가축 기호성이 양호한 시기에 수확하는 것이 중요하며, 최소한 볏짚과 비슷하거나 그 이상의 사료가치를 기대하기 위해서는 7월 중순 이전(늦어도 7월까지)에 수확·이용하는 것이 권장된다. This study was carried out in 2010 to investigate the utilization and forage quality of native grasses, such as Phragmites communis which might reduce the cost of feeding domestic cattle. The regions surveyed were the Haenam ranch in Haenam, Pyeongchang, Wonju, and Yeonggwang. In Haenam, yearly silage production harvested from 300 ha was 2,000 MT (7 MT/ha). All of those round bale silages were self-consumed in that region, and marketing price was 50,000 55,000 won per roll (110 won/㎏). Phragmites communis of 150 ㎝ in length contained 8.4% crude protein (CP) with relative feed value (RFV) 71.9 and 60.1% in vitro dry matter digestibility (IVDMD), which was somewhat more favorable than forage quality of rice straw. The silage quality of Phragmites communis varied greatly by the time of harvest (CP 4.7 6.4%, RFV 62.2 78.9, and IVDMD 41.9 53.9%), even with the same district and of the same original forage materials. Generally, the quality of Phragmites communis silage of was poorer than that of sorghum * sudangrass hybrid. In Pyeongchang, forage quality of Phragmites communis was decreased from 13.9% to 7.6% in CP, 90.7 to 76.1 in RFV, and 72.9% to 54.7% in IVDMD, as plant was getting mature, from 79 ㎝ to 117 ㎝, 121 ㎝ or to 142 ㎝ in length. In Wonju, the quality values of Phragmites communis of 130 ㎝ in length were 8.5% CP, 82.3 RFV and 70.2% IVDMD, while those of matured grasses of 220 ㎝ in length were lower (10.2% CP, 65.1 RFV and 48.9% IVDMD), but this was a little more favorable than quality of rice straw. In Yeonggwang, feeding Phragmites communis was tried in a Hanwoo feed, but stopped due to low profitability. In conclusion, the overall quality of most native grasses including Phragmites communis in this survey was poor. Therefore, we recommend that Phragmites communis and native grasses should be harvested on June or July to obtain richer forage quality in forage values than rice straw.

This research was conducted to obtain basic data with regard to the heating performance that would be produced by installing an aluminum hot water pipe inside the greenhouse with the goal of reducing the heating energy in greenhouse. The research results are summarized as follows. The degree of difference in relation to the temperature by height within the greenhouse during the entire experiment was significant - within the range of 4.0~7.0℃. The temperature difference between incoming and outgoing water was about 3.3℃ greater when FCU was activated compared to when it was not activated. Meanwhile, the amount of energy consumed increased about 36.2~40.1%. The amount of pyrexia per hour also increased by 44.6~52.0%. During the experiment period, circulated flux was within the range of 0.48~0.49 L · s<SUP>?1</SUP> while average fluid speed was 1.53~1.56 m · s<SUP>?1</SUP>. The average temperature difference between incoming and outgoing water was 6.24~11.50℃. The amount of heating value by each set temperature within the minimum outdoor temperature range of ?14.0~?0.6℃ was 135,930~307,150 ㎉, and the range was within the 9,610~19,630 ㎉ · h<SUP>?1</SUP> per hour. This demonstrated that about 23~53% heating energy of the maximum heating load could be supplied. Total radiating value and amount of energy consumed were 2,548,306 ㎉ and 3,075.7 ㎾h, respectively. When heating takes place using oil, which is a fossil fuel, the total amount of light oil consumed was 281.6 L while the cost was 321,000 won. When the electricity cost for farms is applied, the total cost was about 110,730 won, which is about 33.5% of the cost required compared to oil consumption. The temperature at in the experiment area was about 8.3~14.6℃ higher compared to that of the control area.

Background: Steroid-induced hypopigmentation and lipoatrophy is common complication of corticosteroid intralesional injection (ILI). Steroid-induced atrophy is a major problem for Caucasian, but in addition to atrophy, hypopigmentation is an important problem in Asian skin. Objectives: To evaluate the clinical efficacy of normal saline (NS) and polydeoxyribonucleotide (PDRN) ILI plus 308-nm excimer laser on patients with steroid-induced hypopigmentation and lipoatrophy. Methods: Retrospective chart reviews and photographic analysis were performed for patients. NS ILI and PDRN ILI are injected at 30-45° angle for administration into dermis and upper subcutaneous tissue. Patients were divided into 3 groups: group 1 (n=3) received NS ILI plus PDRN ILI plus 308-nm excimer, group 2 (n=2) received NS ILI plus PDRN ILI and group 3 (n=1) received NS ILI. Clinical improvement was assessed by two dermatologists using a 5-point global assessment scale. Results: Six patients were analyzed. The improvement of hypopigmentation was more significantly observed in group1, which combined 308-nm excimer laser. Improvement of lipoatrophy was similarly observed in all three groups. Conclusion Combination therapy of NS ILI, PDRN ILI and 308-nm excimer laser could be effective and safe treatment choice for steroid-induced hypopigmentation and lipoatrophy. This treatment is significant in that it improved not only lipoatrophy but also hypopigmentation.

( Jin Gwi Yoo ),( Xue Mei Li ),( Jae Kyung Lee ),( Sanghyun Park ),( Dongkyun Hong ),( Kyung Eun Jung ),( Young Lee ),( Young-joon Seo ),( Chang Deok Kim ),( Jung-min Shin ),( Chong Won Choi ) 대한피부과학회 2020 대한피부과학회 학술발표대회집 Vol.72 No.1

Background: Increased sebum secretion is considered the main causative factor in the pathogenesis of acne. There is an unmet pharmacological need for a novel drug that can control sebum production with a favorable adverse effect profile. Objectives: To investigate the effect of azidothymidine on lipid synthesis in sebocytes and to identify the underlying mechanism of the inhibitory effect of azidothymidine on IGF-1-induced lipid synthesis in sebocytes. Methods: Immortalized human sebocytes were used for the analysis. Thin-layer chromatography (TLC) and oil Red O staining were performed to evaluate lipid synthesis in the sebocytes. The differentiation, lipid synthesis, mitochondrial biogenesis, and mitophagy in sebocytes were investigated. Results: TLC and oil Red O staining revealed that azidothymidine reduced IGF-1 induced lipid synthesis in the immortalized human sebocytes. Azidothymidine also reduced IGF-1-induced expression of transcriptional factors and enzymes involved in sebocyte differentiation and lipid synthesis, respectively. Moreover, we found that IGF-1 upregulated the levels of PGC-1α, LC-3B, p62, and Parkin, major regulators of mitochondrial biogenesis and mitophagy in immortalized human sebocytes. Conclusion: Our study provides early evidence that azidothymidine may be an effective candidate for a new pharmacological agent for controlling lipogenesis in sebocytes.

Cytoplasmic TrkA Expression as a Screen for Detecting <i>NTRK1</i> Fusions in Colorectal Cancer ¹ ²

Choi, Yuri,Won, Yeo-Jin,Lee, Sojeong,Kim, Ahrong,Kim, Younggeum,Park, Won-Young,Jo, Hong-Jae,Song, Geun Am,Kwon, Chae Hwa,Park, Do Youn Neoplasia Press 2018 Translational oncology Vol.11 No.3

<P><I>NTRK1</I> gene fusions, the targets of multikinase inhibitors, are promising therapeutic targets for colorectal cancer (CRC). However, screening methods for detecting <I>NTRK1</I> gene fusions in CRC tissues have not been reported. In this study, we investigated the potential use of immunohistochemistry (IHC) for detecting <I>NTRK1</I> gene fusions. We performed and compared IHC with fluorescence in situ hybridization (FISH) in 80 CRC patients. TrkA immunostaining was observed to be both membranous and cytoplasmic and was scored semiquantitatively using staining intensity and proportions. The tumors were observed to be <I>NTRK1</I> gene fusion-positive when ≥20 out of 100 nuclei in FISH. A significant correlation between the IHC and FISH results for determination of the <I>NTRK1</I> gene fusions was observed. We measured the cytoplasmic TrkA expression, which showed an area under the receiver operating characteristic (ROC) curve of 0.926 (range: 0.864-0.987, 95% CI, <I>P</I> = .001). By choosing 4.5 (sum of the intensity and proportion scores of cytoplasmic TrkA expression) as the cut-off value for the positive and negative <I>NTRK1</I> gene fusion groups, the sensitivity and specificity for predicting lymph node metastasis were 100 and 83.8%, respectively (<I>P</I> = .001). Specifically, high cytoplasmic TrkA expression (sum of intensity and proportion scores >4) was associated with the presence of <I>NTRK1</I> gene fusions (<I>P</I> < .0001, r = 0.528). Taken together, our data showed that IHC for TrkA can be used as an efficient screening method for detecting <I>NTRK1</I> gene fusions in CRC.</P>
