        Objective: To investigate the expression pattern of transforming growth factor-β-inducible gene-h3 (βig-h3) within rheumatoid synovial tissue and the regulation of βig-h3 synthesis in fibroblast-like synoviocyte (FLS). Methods: Synovial tissues obtained from patients with rheumatoid arthritis and osteoarthritis were obtained during joint replacement surgery. βig-h3 expression was evaluated with immunohistochemical stain. FLS was isolated from synovial tissues and stimulated with cytokines including TGF-β, TNF-α, IL-1β, IFN-γ, IL-6, IL-4, and IL-10. βig-h3 synthesis was measured using semiquantitative RT-PCR, ELISA, immunofluorescence stain, and flow cytometry. Results: Expression of βig-h3 was diffuse and abundant in both lining and sublining layers of rheumatoid synovium, which was more prominent than those of osteoarthritis. Production of βig-h3 in FLS was regulated by TGF-β1 in a dose-dependent manner and was highest at 5 ng/mL of TGF-β1. TNF-α and IL-1β upregulated the production of βig-h3 from FLS synergistically with TGF-β1 but other cytokines such as IL-4, IL-6, IL-10 did not affect. βig-h3 synthesis was efficiently inhibited by dexamethasone at higher dose (100 nM) but not by cyclosporine-A. Conclusion: Production of βig-h3, which is highly upregulated in rheumatoid synovitis, is differentially regulated by inflammatory cytokines.

        Recovery of ionic liquid and sugars from hydrolyzed biomass using ion exclusion simulated moving bed chromatography

        Mai, Ngoc Lan,Nguyen, Nam Trung,Kim, Jin-Il,Park, Hyuk-Min,Lee, Sung-Kyun,Koo, Yoon-Mo Elsevier 2012 Journal of Chromatography A Vol.1227 No.-

        <P><B>Highlights</B></P><P>► Ionic liquid was successfully separated from aqueous sugar mixtures by ion exclusion SMB. ► Ionic liquid and sugar recovery yield depend on the SMB zone flow rates. ► Complete recovery of ionic liquid could be obtained by optimization of SMB zone configuration.</P> <P><B>Abstract</B></P><P>Efficient recovery of ionic liquid (IL) from aqueous mixture of ILs and sugars (which derived from enzymatic or chemical catalyzed hydrolysis of ILs-pretreated biomass) is a major drawback for commercialization of biofuel and platform chemicals production from biomass utilized ILs as pretreatment solvent. In this study, simulated moving bed (SMB) chromatography equipped with ion exclusion column (containing [Emim]<SUP>+</SUP> cation) was investigated to separate sugars (glucose and xylose) which are the main products from biomass hydrolysate and 1-Ethyl-3-methylimidazolium acetate (EmimAc) which is the ILs used for biomass pretreatment. A four-zone SMB system with a configuration of 2-2-2-2 (2 ion exclusion columns in each zone) was used to recover glucose, xylose and EmimAc from their aqueous mixture with yield of 71.38, 99.37 and 98.92%, respectively. Moreover, the optimization of SMB zone configuration by simulation results in a complete recovery of ILs. This result indicates that for the first time, ion exclusion SMB chromatography could be used for complete recovery of ILs from aqueous sugar mixture.</P>

        오골계 증탕액 급여가 흰쥐의 혈중 호르몬, Cytokine 및 특이항체에 미치는 영향

        채현석,안종남,유영모,함준상,이종문,윤상기,최양일,Chae Hyun-Seok,Ahn Chong-Nam,Yoo Young-Mo,Ham Jun-Sang,Lee Jong-Moon,Yoon Sang-Ki,Choi Yang-Il 한국축산식품학회 2004 한국축산식품학회지 Vol.24 No.3

        본 연구는 흰쥐(S.D, ♂)에 각 처리에 따라 기초사료로 시판사료(T$_1$)를 무제한 급여하면서 시험사료로 한약 증탕액 (T$_2$), 오골계 증탕액(T$_3$), 오골계 교잡종 육에 Flavourzyme을 0.1%첨가하여 가수 분해시킨 후 한약제와 혼합하여 증탕시킨 증탕액(T$_4$)을 35일간 경구 투여한 후 흰쥐의 혈청에 대한 glucose및 hormones과 면역학적 변화에 미치는 영향을 조사 한 결과는 다음과 같았다. 비만하였을 때나 과도한 스트레스를 받았을 때 insulin 함량이 증가한다고 하였으나 효소 처리 오골계 교잡종 증탕액을 급여한 처리구에서 체중 증가가 일반사료를 급여한 처리구에 비해 유의적으로(p<0.05) 증가하였어도 insulin 함량이 일반사료 급여구보다 증가하지 않은 것으로 나타나 바람직한 생리현상을 나타냈다. Aldosterone은 스테로이드 계통의 호르몬으로 물의 생리적 밸런스와 혈압조절에 관여하는데 일반사료 급여구에 비해 한약 증탕액, 오골계 증탕액,효소 처리 오골계 증탕액 급여 구에서 낮은 함량을 나타내 고농도 단백 식이의 급여에도 불구하고 aldosterone수치의 저하로 혈압 저하의 효과를 나타 낸 것은 한약을 첨가시켜 고압으로 처리시킨 증탕액의 효과와 가수분해 효소에 의한 소화가 용이하도록 처리한 결과로 사료된다 Cortisol은 스트레스 측정에 감도가 높은 호르몬으로 알려져 있는데 일반사료급여구가 0.67 nmol/L인 반면 증탕액을 급여한 구에서는 0.40∼0.49 nmol/L으로 cortisol 농도가 감소하는 경향을 나타냈는데 이는 aldosterone에서와 같이 한약제와 동물성 단백질을 섭취함에 따른 효과로 사료된다. 흰쥐에 증탕액 급여가 면역반응에 미치는 영향에서 IL-4, IFN-v 및 anti-BSA IgG의 역가는 일반사료를 급여한 처리구에 비해 오골계 증탕액 및 효소 처리 오골계 교잡종 증탕액 급여구에서 spleen과 serum두에서 증가하는 경향을 나타내었는데 앞에서 언급했던 바와 같이 한약(십전대보탕)의 효과와 소화시키기 쉬운 고농도의 단백질 가수분해 물질의 다량 섭취에 의해 면역 활성이 증가되었을 것으로 사료된다. This study was conducted to investigate feeding effects of the high pressure boiled extracts (HPBE) of the Ogol chicken with herbs on glucose, hormones and immunological response (cytokine, specific antibody) of serum in the rat which fed either with normal feed (T$_1$), normal feed + herb HPBE (T$_2$), normal feed + Ogol chicken HPBE (T$_3$), normal feed + mixture of cross-bred Ogol chicken HPBE (T$_4$) hydrolyzed with Flavourzyme 0.1% for 35 days. During experimental period, there was a weak trend to have a higher glucose content for the T$_4$ group with 102.27${\pm}$5.95 mg/dL, but it was not significantly higher than other treatments. For insulin level, T$_1$ group showed numerically a slightly higher level with 6.79${\pm}$4.64 ${\mu}$IU/mL, but the difference was not significant in statistic term due likely to a large variation in comparison with other treatments. The treatments did not significantly alter testosterone level in rat plasma with 1.09, 1.46, 0.98, 1.13 ng/mL in T$_1$, T$_2$, T$_3$ and T$_4$, respectively. T$_4$ treatment increased the aldosterone level to a significantly (p<0.05) higher level (273.33 ng/dL) than other treatments. The extract treated rat showed a tendency in the cortisol level of lower levels than the control group, particularly, it was significantly (p<0.05) lower in T$_3$ group than other groups. T$_3$ and T$_4$ groups showed higher levels for interlukin-4 (IL-4) and anti-BSA IgG in immune cells and plasma. T$_2$, T$_3$ and T$_4$ treatments showed a slightly higher levels in v-interferon (INF-r) than the control, with a greater effect for T4 treatments. These results suggested that HPBE of the cross-bred Ogol chicken hydrolyzed with Flavourzyme increased immunological activity and decreased the concentration of cortisol and aldosterone hormones.

      • 백혈병 마우스 모델의 동종골수이식에서 활성화된 자연살해세포들의 보충이 이식편대백혈병효과와 이식편대숙주반응에 미치는 영향

        엄현석,한치화,박수정,김소연,정낙균,정대철,진종률,최일봉,양형모,서영훈,송현근,최인표,민우성,김춘추 대한조혈모세포이식학회 2001 대한조혈모세포이식학회지 Vol.6 No.1

        배경: 백혈병에서 동종골수이식 (allogeneic bone marrow transplantation)의 성공적 치료 효과를 얻기 위해서는 이식편대숙주반응 (graft-versus-host disease, GVHD) 발생의 극복과 재발의 방지가 중요한 과제이다. 골수를 역류원심성 세포분리 (counterflow centrifugal elutriation, CCE) 방법으로 분리하여 얻은 rotor off (R/O) 세포분획은 T 세포의 수는 적지만 조혈모세포들을 다량 포함하고 있어 동종골수이식에서 주조직적합복합체 (major histocompatibility complex, MHC) 차이를 극복할 수 있고, 이식편의 생착 성공과 GVHD 발생 예방에 효과적이다. 그러나 골수로부터 T 세포를 제거하면 백혈병세포를 공격하는 이식편대백혈병 (graft-versus-leukemia, GVL) 효과가 감소되기 때문에 백혈병 재발의 빈도가 높다. 자연살해세포 (natural killer cell, NK cell)의 보충 첨가는 동종골수이식 후 GVHD 발생을 줄이면서 충분한 GVL 효과를 얻을 수가 있다. 따라서 저자는 분리 후 IL-2로 활성화시킨 NK 세포들을 골수 R/O 세포분획과 함께 백혈병 마우스 모델에 동종이식함으로써 GVHD와 GVL에 미치는 효과를 관찰하였다. 방법: Balb/c (H-2^(d)) 마우스에서 유래된 A20 (murine B-lymphoma/leukemia cell line, H-2^(d)) 백혈병 세포를 이식 2 일 전에 Balb/c 마우스에 주입하고, 치사량의 전신 방사선을 조사한 직후에 Balb/c 또는 C57BL/6 (H-2^(b)) 마우스의 골수 R/O 세포분획을 꼬리정맥을 통하여 주입하였다. 이들은 모두 이식 후 6-8 주 이내에 사망하였다. 동종이식의 대조군 (n=9)에는 1 × 10^(7)의 R/O 세포분획만을 주입하였고, 실험군 (n=9)에는 C57BL/6 마우스의 비장세포들로부터 단클론항체들을 이용한 negative selection방법으로 분리한 후 IL-2로 활성화된 5 × 10^(5)의 NK 세포분획을 1 × 10^(7)의 R/O 세포분획과 함께 주입하였다. GVL 효과의 판정은 이식 후 14 일과 28 일 째 되는 날 마우스에서 골수, 비장, 간 등을 얻어 백혈병 세포들의 침윤을 조직학적으로 관찰하였으며, GVHD의 정도는 육안적 관찰법으로 평가하였다. 결과: R/O 세포분획만을 이식한 대조군의 골수, 비장, 그리고 간 조직에서는 A20 백혈병 세포의 침윤이 각각 89% (8/9), 78% (7/9)와 22% (2/9)에서 관찰되었고, R/O 세포분획과 NK 세포분획을 함께 이식한 실험군에서는 비장과 간을 제외한 골수에서만 89% (8/9)에서 A20 백혈병 세포의 침윤이 관찰되어 두 군 사이에 장기별 분포의 차이를 볼 수 있었다 (P= 0.0001). 한편 GVHD는 두 군 모두에서 경하게 나타나서 유의한 차이는 없었다. 또한 생착 부전으로 사망한 마우스는 없었다. 결론: CCE를 이용하여 T 세포를 제거한 동종골수이식에서 NK 세포의 보충은 GVHD의 악화는 일으키지 않으면서, 백혈병의 진행을 억제하는 GVL 효과를 얻을 수 있었다. Background: Allogeneic bone marrow transplantation (BMT) with T cell-depleted marrow accompanies engraftment failure and relapse of leukemia by a loss of the graft-versus-leukemia (GVL) effect frequently, while it can prevent GVHD. Supplement of NK cells could prevent GVHD and enhance GVL effect in several murine allogeneis BMT models Roter off (R/O) cell fraction obtained by counterflow centriation elutriatio (CCO) contains small number of T cells and many hematopoietic stem cells. The aim of this study was to determine the effect of R/O cell fraction supplemented with IL-2 activated NK cells on GVL and GVHD within the leukemic mouse BMT model. Methods: Inoculation of A20 (H-2d, murine B-lymphoma/leukemia, Balb/c origin) cells into Balb/c mice via the tail vein 2 days prior to lethal total body irradiation (TBI) and infusion of the Balb/c BM or C57BL/6 (H-2b) R/O fraction were performed. It resulted in 100% mortality within 6 to 8 weeks. The irradiated mice in the control group were injected with 1 × 107 R/O cell fraction alone (n=9) and in the experimental group mice were injected with 1 × 107 R/O cell fraction plus 5 × 105 negatively selected IL-2 activated NK cell fractions of the spleens via the tail vein (n=9). On day 14 and 28 after BMT, the bone marrows, spleens, and livers of mice were harvested for histopathologic analysis of the infiltrations of leukemic cells. We then evaluated the GVHD within the mice. Results: A histopathologic study of the recipients receiving R/O fraction alone showed infiltration of leukemic cells, 89% (8/9) in bone marrows, 78% (7/8) in spleens, and 22% (2/9) in livers. The experimental group of mice showed only the infiltration of leukemic cells 89% (8/9) in bone marrows, not in spleens and livers. There were the organ differences of the leukemic cells infiltrations between the two groups (P=0.0001). There were no obvious differences in the GVHD scores between these two groups, and severe GVHD was not observed. There was no engraftment failure among groups. Conclusion: Thus, our findings suggest that R/O cell fraction obtained by CCE and supplemented with NK cells can promote GVL effect without mediating clinically overt GVHD in allogeneic BMT of mouse leukemia.
