고온건식 탈황공정에서 탈황제의 황화, 재생 반응은 비촉매 기고 반응이다. 이러한 비촉매 기고 반응의 수학적 모사는 실험데이터의 설명, 공정의 설계 그리고 scale-up에 있어서 매우 중요한 정보가 된다. 탈황제의 황화, 재생 반응에는 spray dryer로 제조된 zinc titanate 탈황제를 사용하였고, 변형된 미반응핵 모델식에 적용하여 각 반응의 반응속도를 해석한 결과 탈황제의 황화반응에는 화학반응 저항과 고체 상태의 확산 저항이 회합하여 전체반응속도를 지배하며, 이때 반응속도상수는 367.67cm/min 이었고 고체상태의 확산계수는 29.66cm²/min이었다. 또한 재생반응시에 는 화학반응 저항만이 전체반응의 저항으로 관여하며, 이때의 반응속도상수는 3.45x10e cm/min이었다. In the dry-type high temprature gas desulfurization process, sulfidation and regeneration reactions of desulfrrization sorbents are noncatalytic gas-solid reactions. The mathematical modeling of noncatalytic gas-solid reactions is improtant in order to interpret laboratory data and in design and scale-up. Zinc titanate sorbent to manufacture by spray dryer is used in sulfidation and regeneration reactions of desulfuization sorbents. The result which analyzes reaction rate of sulfidation reaction by applying each reactions to modified unreacted core model is that the global reaction rate is controlled by associating with chemical reaction resistance and solid state diffusion resistance. In this case,reaction rate constant is367.67e cm/min and solid state diffusion coefficient is 29.66e cm²/min Also gloval reaction rate of regeneration reaction is controlled only by chemical reaction resistance. In this case, reaction rate constant is 3.45x10e cm/min.

For the evaluation of oncogenesis, progression and prognosis of cancer, CGH is an important technique, because this technique is economic due to utilization of only one probe and lack of culture, screening mathod of whole genome and possibility of retrospective and prospective study. By the CGH, genornic variation of 20 breast cancer tissues, 23 stomach cancer tissues and 16 bladder cancer tissues were analyzed. The results were as followes ; 1. breast cancers The CGH results showed gains on chromosomes 8q(40%), lq(30%), 17q(15%), 20q(15%), 18q (15%), 5p(15%), and 13q(15%). The Deletions were on chromosomes 17p(45%) and 22q(20%). High-level amplifications(green/red ratio >1.5) were noted on chromosomes 1p31, iq, 3q25-qter, 5p, 7q31-qter, 8q, 9q22-qter, 10p, l1p, 11q22-qter, 12p, 12q24, 14g21-qter, 15q23-qter, 17q, 18p, 18q12-qter, 20p, and 20q. By comparison with infiltrating ductal carcinoma, the two medullary carcinomas showed high-level amplification on chromosomes iq3l, lq, 8q, 10p, 11p and 12p. 2. stomach cancers 1) Usual amplification sites of genome were lq, 13q, 17q, 20p,q. 2) 17p was the most common deletion site. The other sites of the deletion were lq, 4q. 3) In intestinal type of stomach cancer, genomic variation is more common than diffuse type. 4) In the cases of no evidence of lymph node metastasis, deletion of 17p is absent but amplification of 8q is obvious in the case of lymph node metastasis. 3. bladder cancers Common amplification of copy numbers of DNA sequences by CGH were seen at 1q, 3q, 4q, 5p, 6pq, 7p, 8q, 11q, 12q, 13q, 17q, 18q and 20pq(more than 20% of cases). High level amplification was noted at 1p32, 3p2l, 3q24, 4q26, 8q21-ter, 11q14-22, 12q15-21, 12q21-24, 13q 21-31, 17q22, and 18q22. Deletions were noted at 2q21-qter, 4q13-23, 5q, 8p12-22, 9pq, 11p13-15 (more than 20% of cases).

Epidermal growth factor improves the migration and contractility of aged fibroblasts cultured on 3D collagen matrices

KIM, DAEHWAN,KIM, SO YOUNG,MUN, SEOG KYUN,RHEE, SANGMYUNG,KIM, BEOM JOON UNKNOWN 2015 INTERNATIONAL JOURNAL OF MOLECULAR MEDICINE Vol.35 No.4

<P>Epidermal growth factor (EGF) plays a critical role in fibroblasts by stimulating the production of collagen and supports cell renewal through the interaction between keratinocytes and fibroblasts. It is well known that the contractile activity of fibroblasts is required for the remodeling of the extracellular matrix (ECM), which contributes to skin elasticity. However, the role of EGF in the contraction of aged fibroblasts under 3-dimensional (3D) culture conditions is not yet fully understood. In the present study, we demonstrated that young fibroblasts spread and proliferated more rapidly than aged fibroblasts under 2-dimensional (2D) culture conditions. Cell migration assay using a nested collagen matrix revealed that the migration of young fibroblasts was also greater than that of aged fibroblasts under 3D culture conditions. However, the addition of recombinant human EGF (rhEGF) resulted in the enhanced migration of aged fibroblasts; the migration rate was similar to that of the young fibroblasts. The aged fibroblasts showed decreased cluster formation compared with the young fibroblasts on the collagen matrix, which was improved by the addition of rhEGF. Furthermore, cell contraction assay revealed that the basal contractility of the aged fibroblasts was lower than that of the young fibroblasts; however, following treatment with rhEGF, the contractility was restored to levels similar or even higher to those of the young fibroblasts. Taken together, our results suggest that rhEGF is a potential renewal agent that acts to improve the migration and contraction of aged fibroblasts more efficiently than young fibroblasts under 3D culture conditions; thus, EGF may have valuable regenerative effects on aged skin.</P>

( Young-jae Cho ),( Jae Young Moon ),( Ein-soon Shin ),( Je Hyeong Kim ),( Hoon Jung ),( So Young Park ),( Ho Cheol Kim ),( Yun Su Sim ),( Chin Kook Rhee ),( Jaemin Lim ),( Seok Jeong Lee ),( Won-yeon 대한결핵 및 호흡기학회 2016 Tuberculosis and Respiratory Diseases Vol.79 No.4

There is no well-stated practical guideline for mechanically ventilated patients with or without acute respiratory distress syndrome (ARDS). We generate strong (1) and weak (2) grade of recommendations based on high (A), moderate (B) and low (C) grade in the quality of evidence. In patients with ARDS, we recommend low tidal volume ventilation (1A) and prone position if it is not contraindicated (1B) to reduce their mortality. However, we did not support high-frequency oscillatory ventilation (1B) and inhaled nitric oxide (1A) as a standard treatment. We also suggest high positive end-expiratory pressure (2B), extracorporeal membrane oxygenation as a rescue therapy (2C), and neuromuscular blockage for 48 hours after starting mechanical ventilation (2B). The application of recruitment maneuver may reduce mortality (2B), however, the use of systemic steroids cannot reduce mortality (2B). In mechanically ventilated patients, we recommend light sedation (1B) and low tidal volume even without ARDS (1B) and suggest lung protective ventilation strategy during the operation to lower the incidence of lung complications including ARDS (2B). Early tracheostomy in mechanically ventilated patients can be performed only in limited patients (2A). In conclusion, of 12 recommendations, nine were in the management of ARDS, and three for mechanically ventilated patients.

본 연구에서는 가장 대중적인 한국의 전통주 막걸리의 제조과정이 기능성 분획에 미치는 영향을 확인하고자 하였다. Saccharomyces cerevisae 균주별, 발효온도별, 발효기간 별로 다르게 만든 막걸리로부터 ethanol 침전법을 이용해 crude polysaccharides(CP-M)를 분리하여 peritoneal macrophage 활성화 효과와 세포 배양액 중의 interleukin(IL)-6와 -12 농도에 미치는 영향을 조사하였다. S. cerevisae 89-1-1, 98-2, 268-3, 113-4의 4가지 효모 중 S. cerevisae 113-4로 발효한 CP-M을 peritoneal macrophage에 10 ㎍/mL 처리했을 때 세포 배양액 중 nitric oxide(NO) 농도 33.3 ㎛로 가장 높았으며, IL-6와 -12의 농도 역시 116.3 pg/mL와 59.8 pg/mL로 가장 높게 나타났다. S. cerevisae 113-4를 접종하여 온도별로 발효한 발효물에서 분리한 CP-M 중 25℃에서 발효 후 얻은 CP-M을 peritoneal macrophage 세포에 처리했을 때, NO 농도가 Control 대비 2.7∼3.3배, IL-6 농도는 5.7배까지 증가하였다. 그러나 15, 20, 30℃에서 발효하여 얻은 CP-M의 경우 peritoneal macrophage의 NO와 IL-6 생성량에는 Control(무처리구)과 비교하여 영향이 없었다. 발효기간별 영향을 관찰한 결과 5일째 술덧에서 분리한 CP-M에 의한 NO 생성량이 가장 높아 0일째 MCP에 비해 2.2배 증가하였다. 그러나 급격하게 IL-6와 -12의 농도가 감소한 10일째 MCP를 제외하고는 발효기간에 따른 IL-6와 -12의 유의적인 농도 차이는 없었다. 이상의 결과에서 가장 활성이 좋은 발효 조건은 S. cerevisae 113-4를 접종하여 25℃에서 5일간 발효시킨 술덧의 CP-M이었다. 이때 CP-M의 조성은 neutral sugar 함량 78.6%, acidic polysaccharide 11.6%, 단백질 9.8%였다. 특히 neutral sugar의 구성당 비율은 mannose 47.8 ㏖e%, glucose 29.6 ㏖e%, galactose 12.7 ㏖e%였다. 이상의 결과에서 면역증강 활성이 있는 기능성 조다당 CP- M은 mannose 함량이 높은 yeast 유래의 extracellular polysaccharide로 추정하였다. Various microorganisms are involved in the fermentation of Mageoli, Korean traditional liquor. Among them, the most predominant microorganism is yeast, including Saccharomyces cerevisae. This study investigated the effects of crude polysaccharides separated from Mageoli mash (CP-M) on activation of peritoneal macrophages in cell culture medium. Four types of yeasts, S. cerevisae 89-1-1, 98-2, 268-3, and 113-4, were used. When peritoneal macrophages were treated with 10 ㎍/mL of CP-M fermented with S. cerevisae 113-4, the concentration of nitric oxide (NO) in the medium was highest (33.3 ㎛). The concentrations of IL-6 and -12 were also highest at 116.3 pg/mL and 59.8 pg/mL, respectively. In the case of CP-M cultured at 15, 20, and 30℃ after inoculation with S. cerevisae 113-4 and fermented at different temperatures, production of NO and IL-6 by peritoneal macrophages did not change compared to the control. For CP-M obtained after fermentation at 25℃, however, NO concentration increased 2.7~3.3 fold and IL-6 concentration by 5.7 fold compared to the control. Furthermore, the effect of fermentation period on expression of CP-M functionality was examined. NO production by CP-M of the 5th day mash was highest, increasing 2.2 fold compared to 0-day CP-M. However, there were no significant differences in concentration of IL-6 or -12 according to different fermentation periods, although CP-M showed a large decrease after 10 days. The results show that fermentation conditions with the highest activity were observed in CP-M inoculated with S. cerevisae 113-4 and fermented at 25ºC for 5 days. CP-M consisted of 78.6% neutral sugar, 11.6% acidic polysaccharide, and 9.8% protein. In particular, the sugar composition of neutral sugar consisted of mannose (47.8%), glucose (29.6%), and galactose (12.7%). Based on the results, CP-M is assumed to be an extracellular polysaccharide originating in yeast with high mannose content.
