Background: Calcineurin plays a crucial role in T cell activation, cell growth, apoptosis, and angiogenesis, and its over-expression has been implicated in the pathogenesis of cardiomyopathy and stroke. However, the expression and function of calcineurin in the pathologic lesion of chronic inflammatory diseases, like rheumatoid synovium, remain to be defined. This study was aimed to determine the role of calcineurin in inflammatory arthritis and investigate the expression and function of calcineurin in the rheumatoid synovium and synoviocytes, the actual site of chronic inflammation. Methods: Immuno-histochemical staining using specific antibody to calcineurin was perfomed in the synovium of rheumatoid arthritis (RA). Fibroblast-like synoviocytes (FLS) from RA and osteoarthritis (OA) patients were isolated from RA and OA patients, and cultured with IL-1${\beta}$ and TNF-${\alpha}$ in the presence or absence of cyclosporin A, a calcineurin inhibitor. The calcineurin expression was assessed by phosphatase assay and Western blotting analysis. IL-6, -10, -17, matrix metalloproteinase (MMP)-1, -2, -3, and -9 released into the culture supernatants were measured by ELISA. After transfection with GFP-Cabin 1 gene into synoviocytes, the levels of IL-6 and MMPs were measured by ELISA. Results: Calcineurin was highly expressed in the lining layer of synovium and cultured synoviocytes of RA patients. The elevated calcineurin activity in the rheumatoid synoviocytes was triggered by proin flammatory cytokines such as IL-1${\beta}$ and TNF-${\alpha}$. In contrast, IL-10, an anti-inflammatory cytokine, failed to increase the calcineurin activity. The targeted inhibition of calcineurin by the over-expression of Cabin 1, a natural calcineurin antagonist, inhibited the production of IL-6 and MMP-2 by rheumatoid synoviocytes in a similar manner to the calcineurin inhibitor, cyclosporin A. Conclusion: These data suggest that abnormal activation of calcineurin in the synoviocytes may contribute to the pathogenesis of chronic arthritis, and thus provide a potential target for controlling inflammatory arthritis.

A novel glucanhydrolase from a mutant of Lipomyces starkeyi KSM 22 has additional amylase activity besides mutanolytic activity and has been suggested as promising anti-plaque agent. It has been shown effective in hydrolysis of mutan, reduction of mutan formation by Streptococcus mutans and removal pre-formed sucrose-dependent adherent microbial film and has been strongly bound to hydroxyapatitie. These in vitro properties of Lipomyces starkeyi KSM 22 glucanhydrolase are desirable for its application as a dental plaque control agent. In human experimental gingivitis　model and 6 month clinical trial, mouthrinsing with Lipomyces　starkeyi KSM 22 dextranase was comparable to 0.12% chlorhexidine mouthwash in inhibition of plaque accumulation and gingival inflammation and local side effect was negligible. This study was aimed to evaluate the cytotoxic effect of Lipomyces starkeyi KSM 22 glucanhydrolase on human gingival fibroblasts. Primary culture of human gingival fibroblasts at the 4th to 6th passages were used. Glucanhydrolase solution was made from lyophilized glucanhydrolase powder from a mutant of Lipomyces stakeyi KSM 22 solved in PBS and added to DMEM medium to the final concentration of 0.5, 1, and 2 unit. Cells were exposed to glucanhydrolase solution or 0.1 % chlorhexidine and the cells cultured in DMEM with 10% FBS and 1% antibiotics as control. After exposure, the morphological change, cell attachment, and cell activity by MTT assay were evaluated in 0.5, 1.5, 3, 6, 24 hours after treatment. The cell proliferation and cell activity was also evaluated at 2 and 7 days after 1 minute exposure, twice a day. The cell morphology was similar between the Lipomyces smkeyi KSM 22 glucanhydrolase groups and control group during the incubation periods, while most fibroblasts remained as round cell regardless of incubation time in the chlorhexidine group. The numbers of the attached cells in the glucanhydrolase groups were comparable to that of control and significantly higher than the chlorhexidine group. The numbers of the proliferated cells in the glucanhydrolase groups at 7 days of incubation were comparable to the control group and higher than the chlorhexidine group. The cell activity in glucanhydrolase groups paralleled with the increased cell number by attachment and proliferation. According to these results, Lipomyces starkeyj KSM 22 glucanhydrolase has little harmful effect on attachment and proliferation of human gingival fibroblasts, in contrast to 0.1% chlorhexidine which was cytotoxic to human gingival fibroblasts. Therefore this glucanhydrolase preparation is considered as a safe and promising agent for new mouthwash formula in the near future.

Steroidal alkaloid인 cyclobuxine D의 carrageenin으로 유발한 늑막염과 croton oil로 유발한 육아종양에 대한 영향을 관찰하고 그 작용을 aspirin, dexamethasone과 hydrocortisone의 작용과 비교하였다. Carrageenin으로 유발한 늑막염에서 혈장 삼출정도는 pontamine sky blue을 정맥으로 투여하여 20분 동안 늑막염 삼출물로 삼출되어 나오는 양으로 측정하였다. Cyclobuxine D는 용량적으로 삼출물의 양과 20분 동안 삼출되는 pontamine sky blue의 양을 감소시켰다. Cyclooxygenase 억제제인 aspirin과 phospholipase $A_2$를 억제하여 결과적으로 cyclooxygenase와 lipoxygenase의 생성물을 차단하는 dexamethasone은 현저하게 carrageenin으로 나타나는 염증현상을 억제하였다. Cyclobuxine D는 croton oil로 유발한 육아종양에서 종양 부위에 직접 투여하거나 근육내로 투여해도 pouch내 염증물 양과 pouch wall의 무게를 현저하게 억제하였다. Dexamethasone과 hydrocortisone은 육아종양의 형성을 현저히 억제하였으며 , dexamethasone은 근육내로 투여 하였을 때 육아종양 형성을 완전히 억제하였다. 이상의 결과에서 나타난 cyclobuxine D의 항염증 작용은 prostaglandins의 생성억제 또는 polymorphonuclear cell (PMN)의 유주 억제와 밀접한 관련이 있을 것으로 사려된다.

Objective : This study was performed to investigate the anti-fibrogenic effect and changes of inflammation-related genes by YBR I and YBR II (YBR I: Arteisiae Capillaris Herba, Atractylodis Rhizoma Alba, Hoelen/ YBR II: YBR I +Sanguisorbae Radix, Biotae Cacumen, Cirsii Japonici Herba) on HSC(hepatic stellate cells)-T6 and TAA-induced rat liver tissue. Materials and Methods : HSC-T6 were treated with various concentrations of distilled-water extract YBR I and YBR II extract for 24, 48 and 72 hours. After the treatment, cell viability, proliferation, procollagen levels and IL-6 levels were measured by using MTT Assay, BrdU Assay, Procollagen Type 1 C-peptide EIA kit, and Murine IL-6 ELISA Development kit. Rat liver fibrosis was induced by intraperitoneal TAA injection of 150mg/kg 3 times a week for 6 weeks. After the treatment, body weight, liver & spleen weights, liver function test, complete blood cell count and change of portal pressure were studied. In addition, gene expressions of ASMA, IL-6, MMP-2, TIMP-1 and TIMP-2, all of which are known to be associated with liver fibrosis, were analyzed by using Real-Time PCR. After YBR I and YBR IItreatment, percentages of collagen in TAA-induced rat liver tissue were measured. Results : The viability and proliferation of the HSC-T6 decreased as the concentration increased. The production of procollagen decreased as the concentration increased. The production of IL-6 was little influenced by YBR I and YBR II. There was no difference in rat body weight between the TAA-only group and the YBR groups. Compared with rat liver weight of TAA-only group, that of the YBR groups increased. In the YBR I group, the serum level of AST elevated by TAA injection significantly decreased and in the YBR I and II group, the serum level of ALP and ALT elevated by TAA injection decreased. In the YBR I group, white blood cell count elevated by TAA injection decreased but platelets increased. In the YBR I group, the portal pressure elevated by TAA injection significantly decreased. Decreases in the gene expression of ASMA and MMP-2 were observed in the YBR I group. The gene expression of IL-6 was little influenced by YBR I and YBR II -treated groups. In the histological finding, TAA injections caused severe fibrosis, but YBR I and YBR II treatment significantly reduced the amounts of hepatic collagens. Conclusions : These results suggest that YBR I and II have inhibitory effects on the hepatic fibrogenesis.

28개의 아미노산으로 이루어져 있는 Ghrelin은 위 기저부의 X/A-유사 신경내분비 세포에서 주로 합성 분비되는 물질로 음식의 섭취나 비만, 에너지 항상성 등을 조절하는 역할을 하며, 이러한 Ghrelin 활성화는 수용체인 G-protein coupled growth hormone secretagogue receptor-1a (GHS-R1a)와 결합을 통해 일어난다. 최근 보고된 자료에 따르면, ghrelin과 수용체는 위나 시상하부, 뇌하수체 등뿐만 아니라 T 세포나 단핵구 및 대식세포 등 면역 세포에서도 생성되며, 염증반응을 유도하는 사이토카인의 생성을 억제하는 역할을 한다. 또한 흉선의 퇴화 등 면역기관에 있어서도 중요한 호르몬으로 보고되고 있지만 그 기전이나 기능에 대한 연구가 아직 미미한 실정이다. 본 연구에서는 흉선에서 T 세포의 성숙이나 세포활성을 억제하는 물질로 알려져 있는 덱사메타손(Dexamethasone; DEX)으로 세포사멸을 유도시킨 흉선세포에 ghrelin을 처리하여 세포사멸 억제효과를 알아보았다. 그 결과 Ghrelin은 세포사멸에 중요 단백질인 Caspase-3와 PARP 및 Bim의 활성화가 in vivo 및 in vitro 모두에서 효과적으로 저해됨을 확인할 수 있었으며, 이러한 세포사멸의 억제효과는 ghrelin을 처리할 경우 DEX에 의해 활성화된 Glucocorticoid 수용체(GR)의 인산화의 억제와 HSP90 등과 복합체를 이루고 있는 GR이 활성화되면서 분해되는 과정을 억제시켜 결과적으로 핵 안으로 이동하는 과정을 억제하는 기전을 통해 나타남을 알 수 있었다. 이러한 결과 등을 통해 볼 때, ghrelin은 약물이나 체내 생리적 스트레스 등으로 인해 발생하는 흉선 내 면역세포들의 세포사멸에 도움을 줄 것으로 사료되며, 나아가 이로 인한 흉선위축을 보호할 수 있는 치료 후보물질로서의 연구를 기대할 수 있으리라 사료된다.

Background Wound healing is an interaction of a complex signaling cascade of cellular events, including inflammation, proliferation, and maturation. $K^+$ channels modulate the mitogen-activated protein kinase (MAPK) signaling pathway. Here, we investigated whether $K^+$ channel-activated MAPK signaling directs collagen synthesis and angiogenesis in wound healing. Methods The human skin fibroblast HS27 cell line was used to examine cell viability and collagen synthesis after potassium chloride (KCl) treatment by Cell Counting Kit-8 (CCK-8) and western blotting. To investigate whether $K^+$ ion channels function upstream of MAPK signaling, thus affecting collagen synthesis and angiogenesis, we examined alteration of MAPK expression after treatment with KCl (channel inhibitor), NS1619 (channel activator), or kinase inhibitors. To research the effect of KCl on angiogenesis, angiogenesis-related proteins such as thrombospondin 1 (TSP1), anti-angiogenic factor, basic fibroblast growth factor (bFGF) and vascular endothelial growth factor (VEGF), pro-angiogenic factor were assayed by western blot. Results The viability of HS27 cells was not affected by 25 mM KCl. Collagen synthesis increased dependent on time and concentration of KCl exposure. The phosphorylations of MAPK proteins such as extracellular-signal-regulated kinase (ERK) and p38 increased about 2.5-3 fold in the KCl treatment cells and were inhibited by treatment of NS1619. TSP1 expression increased by 100%, bFGF expression decreased by 40%, and there is no significant differences in the VEGF level by KCl treatment, TSP1 was inhibited by NS1619 or kinase inhibitors. Conclusions Our results suggest that KCl may function as a therapeutic agent for wound healing in the skin through MAPK signaling mediated by the $K^+$ ion channel.

김치유산균인 L. plantarum CIB 001(KCTC 11717 bp)을 고콜레스테롤을 식이를 섭취시킨 흰쥐에게 급여하여 혈청 지질 성상 및 간 조직의 변화를 살펴보았다. 4주간의 실험식이로 고콜레스테롤 유도한 후, 6주간 고콜레스테롤 식이와 함께 CIB 001 유산균을 $5.0-7.5{\times}10^9$ CFU/day 수준으로 급여한 결과 총 콜레스테롤을 HCD군에 비해 약 30% 정도 유의하게 감소시켰고 중성지방을 약 32% 정도 유의하게 감소시켰다. HDL-콜레스테롤에 있어서는 HCD군에 비해 CIB 001를 급여한 군(HCDL)이 약 40% 유의적으로 증가하였고, LDL-콜레스테롤은 감소하는 경향을 보였으나 표준편차가 커서 유의성이 없었다. 동맥경화지수(AI)와 심장위험인자(CRF)를 비교하였을 때, HCD군에 비하여 HCDL군에서 AI가 약 6배 유의하게 낮아졌고 CRF도 약 1.9배 유의적으로 낮아졌다. 또한, 간 조직을 관찰한 결과, 고콜레스테롤 식이에 의해 유발된 지방 변성과 손상의 경우 HCDL군에서 중심정맥을 중심으로 정상 모양의 재생과 지방 변성을 감소시키는 것이 관찰되었다. 따라서 CIB 001의 투여가 콜레스테롤 과잉혈증 상태에서 높아진 혈장 지질을 저하시키고 간 기능을 개선시켰으며 동맥경화와 심장질환의 가능성을 감소시키는 것으로 나타냈다.
