  • The purpose of this study is that evaluate the distribution and biological roles of TNF-a, interleukin-1${\beta}$(IL-1${\beta}$), interleukin-6(IL-6) and tissue inhibitors of metalloproteinase-1(TIMP-1) in the synovial fliud of patients with non-inflammatory chronic temporomandibular joint(TMJ) disorders in relation to pain during joint movements and magnetic resonance imaging(MRI) findings. TMJ synovial fluids aspirates were obtained from 36 patients (36 joints) with chronic TMJ disorders and from 8 controls(8 joints). Patients were divided to four groups. The control group was from healthy volunteers(8 joints), group I(18 joints) was patients with anterior disc displacement with reduction, group II(5 joints) was patients with disc displacement without reduction and group III (5 joints) was osteoarthritis. The TNF-${\alpha}$, IL-1${\beta}$ and IL-6 levels in the aspirates were determined by using an enzyme-linked immunosorbent assay and the TIMP-1 level was measured by an enzyme immunoassay. Following examinations for pain during joint movements and MRI observations, these cytokines' level and frequencies of detection were compared. The level of IL-1${\beta}$was not significant different in all groups. but the level of TNF-${\alpha}$, IL-6 and TIMP-1 were significant different among groups. The level of IL-6 and TIMP-1 were correlated to pain during movement(p<0.01) and the level of TNF-a(p<0.05). Also, the level of IL-6 was correlated to the level of TIMP-1(p<0.01). Especially, The level of the TIMP-1 level was significantly correlated to the pain during movement and showed very high levle of Pearson's correlation coefficient (r=0.833)(p<0.001). The results indicated that the TNF-${\alpha}$, IL-6 and TIMP-1 levels in the TMJ aspirates of patients with chronic TMJ disorders have been raised. Especially, IL-6 and TIMP-1 were very high levels in the patients who were degraded in the TMJ. Also, TNF-${\alpha}$, IL-6 and TIMP-1 showed the significant correlation in the chronic temporomandibular joint disorders. Therefore I suggest that these cytokines were also correlated to the pain during movement in the chronic temporomandibular joint disorders.

  • This study was designed to examine the tissue levels of interleukin-$1{\alpha}$(IL-$1{\alpha}$), interleukin-$1{\beta}$(IL-$1{\beta}$) and tumor necrosis factor-${\alpha}$(TNF-${\alpha}$) in inflamed human dental pulps and periapical lesions, and to determine the relationship between each cytokine and pulpal and periapical pathosis. The pulps used in this experiment, were obtained in routine endodontic treatment and the periapical lesions in periapical surgery after clinical diagnoses were performed. These specimens were divided into four groups as normal pulp group(control group, n=9), acute pulpitis group(n=g), chronic pulpitis group(n= 10) and periapical lesion group(n= 18) and stored in liquid N2. For extract preparation, tissues were finely minced with a scalpel, and the fragments were incubated in $0.5m\ell$ homogenizing buffer (0.1 mol/L potassium chloride, 0.02 mol/L TRIS; pH=7.6) for two hours and grinded with glass homogenizer. Debris was removed by centrifugation and supernatants were immediately tested with enzymelinked immunosorbent assay (ELISA, R&D Co., Minneapolis, USA). Following results were obtained; 1. The concentrations of IL-$1{\alpha}$ in all experimental groups were significantly higher than in control group(p<0.05). And the concentrations of IL-$1{\alpha}$ in periapical lesion group were somewhat higher than in two pulpitis groups, but the differences among those groups were not stastically significant (p>0.05). 2. The concentrations of IL-$1{\beta}$ in all experimental groups were significantly higher than in control group (p<0.05), and all the experimental groups expressed similar concentrations. 3. The concentrations of TNF-${\alpha}$ in all experimental groups were higher than in control group but only the differences between chronic pulpitis group and control group were statistically significant(p<0.05). And the concentrations of TNF-${\alpha}$ in acute and chronic pulpit is groups were higher than in periapical lesion group but only the differences between chronic pulpitis group and periapical lesion group were statistically significant (p<0.05). 4. There was significant correlation only between IL-$1{\alpha}$ and IL-$1{\beta}$ in periapical lesion group (p<0.05).

  • Objective: To investigate the effects of pioglitazone on controlled ovarian stimulation (COS), IVF outcomes, and follicular fluid (FF) cytokine concentrations in patients with polycystic ovary syndrome (PCOS). Methods: Eighty-six infertile patients with PCOS resistant to clomiphene citrate were randomized to receive pioglitazone (30 mg/day) or placebo on the starting day of oral contraceptive (OC) pretreatment, followed by an IVF protocol using a GnRH antagonist. Pioglitazone or placebo was administered once daily from the starting day of OC to the day of hCG injection. Results: Total dose and days of recombinant follicle-stimulating hormone administered, and the numbers of retrieved and mature oocytes, were significantly lower in the pioglitazone group than in the control group. FF tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) and interleukin-6 (IL-6) concentrations at oocyte retrieval were also significantly lower in the pioglitazone group. The clinical pregnancy rate was higher and the incidence of severe ovarian hyperstimulation syndrome was lower in the pioglitazone group, but the differences were not statistically significant. Conclusion: Pioglitazone reduces FF TNF-${\alpha}$ and IL-6 levels, and may improve ovarian response to COS in patients with PCOS.

  • Objectives : This study was designed to investigate the effects of SuJeom-san(SJS) extract in rats with caerulein-induced acute pancreatitis (AP). Methods : We examined changes of pancreatic weight, histological, immunohistochemical and gene expression of cyclooxygenase (COX-2). Thirty-six adult male Sprague-Dawley rats were divided into six groups as follow: normal(Nor), caerulein-induced (Con), caerulein + cefotaxime sodium(CT), caerulein + SJS 3 mg/kg(SJSA), caerulein + SJS 6 mg/kg(SJSB) and caerulein + SJS 12 mg/kg(SJSC) groups. Pancreatic tissues of rats from all groups were removed for histological observation and light, and electron microscopic examination. Platelet activating factor(PAF) and Interleukin-6(IL-6) levels were determined spectrophotometrically. Results : The ratio of pancreas/body weight was significantly(p<0.05) increased in the Con compared with Nor, but significantly(p<0.05) decreased in SJSA, SJSB, SJSC and CT groups compared with Con. Caerulein administration significantly increased(p<0.05) the levels of amylase, but SJSA, SJSB, SJSC and CT significantly(p<0.05) reduced the levels of these enzymes. The levels of platelet activating factor(PAF) increased in Con compared with Nor, but decreased in SJSA, SJSB, SJSC and CT groups compared with Con. Interleukin-6(IL-6) levels increased significantly in all groups compared to Nor at 6 hrs, but significantly(p<0.05) reduced in SJSA, SJSB, SJSC and CT groups compared with Con at 24 hrs. The levels of tumor necrosis factor(TNF)-${\alpha}$ levels increased in all groups compared to Nor at 6 hrs, but significantly(p<0.05) reduced in SJSA, SJSB, SJSC and CT groups compared with Con at 24 hrs. The COX-2 positive materials were observed in the pancreas of the Con, but these positive materials were decreased in the SJS extract treatment group. Conclusion : SJS is potentially capable of limiting pancreatic damage during AP by restoring the fine structure of acinar cells and tissue; therefore, we conclude that SJS may have beneficial effects in the treatment of caerulein-induced AP.

  • Probiotics are live microorganisms that confer a health benefit on the host. Duolac-Gold is a mixture of seven probiotic bacteria containing three species of Bifidobacteria, two species of Lactobacillus, and Streptococcus thermophilus. The aim of this study was to assess the anti-inflammatory effects of Duolac-Gold in an inflammatory bowel disease (IBD) mouse model. IBD was induced by administering 1.5% dextran sulfate sodium (DSS) for 10 days. After induction of DSS-induced colitis, Duolac-Gold was orally administered at three different concentrations. Interestingly, Duolac-Gold treatment accelerated IBD healing, and anti-inflammatory activity was assessed by weight loss, length of the colon, and a microscopic damage score by histology. The expression of inflammatory related cytokines was measured in colon tissues and serum. Of these cytokines, the expression of interleukin-6 decreased remarkably after Duolac-Gold treatment. Taken together, these results suggest that Duolac-Gold treatment is effective in IBD healing by regulating IL-6.

  • 배경: 적혈구세척법(체외순환로 충전시 사용되는 농축 적혈구를 헤파린 용액으로 세척하여 충전)은 충전용 농축적혈구액에 포함되어 있는 염증반응 전구 물질 및 각종 손상된 세포 및 미립자들을 제거할 수 있으며, 전순환-초여과법(체외순환전에 체외순환로를 자체 전순환 시킨후 초여과법을 적용)은 체외순환로에 의한 초기 염증반응을 둔화시키고 염증반응 매개체들을 제거할 수 있다 본 연구자는 상기 방법들이 수술시 형성되는 염증반응 매개체중 허혈후 재관류 손상에 관여하는 각종 사이토카인들의 형성을 억제할 수 있을 것이라 가정하여, 실제 임상 환자를 대상으로 상기 방법들을 적용하면서 각종 사이토카인의 체외순환 및 수술 시간에 따른 변화를 측정하여 비교 분석하고자 하였다. 대상 및 방법: 본 연구자는 심실중격결손증으로 개심술을 받는 48명의 환아를 대상으로 하여, 대조군(C군, n=12), 적혈구 세척군(W군, n=12), 전순환-초여과군(F군, n=12), 혼합군(WF군, n=12) 으로 나누어 적혈구 세척법과 전순환-초여과법을 시행한 후에 체외순환을 적용하면서 tomor necrosis factor-$\alpha$(TNF-$\alpha$)와 interleukin-6 (IL-6) 및 interleukin-8 (IL-8) 등의 체외순환 및 수술 시간경과에 따른 변화를 측정 비교 분석 하였다. 결과: TNF-$\alpha$, IL-6, IL-8 등의 변화는 시간에 따라 각군간 유의한 차이를 보였다(p=0.001, p=0.001, p=0.005). TNF-$\alpha$의 변화는 대조군(C군), 세척군(W군), 전순환-초여과군(F군) 사이에서 유의한 차이를 보이지 않았으나(p=0.264), 혼합군(WF군)에서는 다른 군들에 비해 낮게 측정되었다(p<0.05). IL-6의 변화는 세척군(W군), 전순환-초여과군(F군), 혼합군(WF군) 사이에서는 유의한 차이가 없었으나(p=0.053), 각군 모두 대조군(C군)에 비해 낮게 측정되었다(p<0.05). IL-8의 변화는 세척군(W군), 전순환-초여과군(F군), 혼합군(WF군) 사이에서 유의한 차이가 없었으며(p=0.067), 대조군(C군)과 전순환-초여과군(F군) 사이에서도 유의한 차이를 보이지 못하였으나(p=0.086), 세척군(W군)과 혼합군(WF군)에서는 대조군(C군)에 비해 낮게 측정되었다(p<0.05). 결론: 이상의 결과는 적혈구 세척법과 전순환-초여과법이 체외순환을 이용한 개심수술시 사이토카인 형성 억제에 효과가 있음을 구명하였다. 그러나, 상기 방법들을 임상에서 확대적용 하기 위해서는 실질적으로 임상 경과에서 얻을 수 있는 장점에 관한 연구가 추가적으로 시행되어야 하겠다.

  • Cytoskeleton은 세포핵과 세포외 기질을 연결하고 있어서 기질에 가해지는 물리적 힘에 의해 cytoskeletal change가 유도되고 이에 의해 세포의 개조활성이 영향을 받는다고 생각되어 왔다. 본 연구는 골모세포 활성에 대한cytoskeletal change의 역할을 규명하기 위한 것으로서, 신생 백서로부터 조골세포양 세포를 분리, 배양하고 네가지 농도의 cytochalasin B(CB) 또는 colchicine(COL)을 3시간 처리하였다. 다시 배양액을 교환하고 24시간 동안 배양하여 prostaglandin $E_2\;(PGE_2)$, interleukin-6(IL-6), tumor necrosis factor-$\alpha$(TNF-$\alpha$) 및 matrix metalloproteinase-1 (MMP-1) 생산을 측정하고 통계적으로 비교하였으며 cytoskeletal protein actin 변화를 관찰하기위하여 면역형광염색하고 형광현미경으로 관찰하여 다음과 같은 결과를 얻었다: 1. CB 처리군에서 $PGE_2$ 생산이 증가되는 경향을 보였고 COL 처리군에서는 약물농도에 비례하여 증가하였다. 2. IL-6 생산은 CB농도 1.0 ${\mu}g/ml$일때를 제외하고 증가되었다. 3. TNF-$\alpha$도 CB 농도가 1.0 ${\mu}g/ml$ 일때를 제외하고 증가하였다. 4. MMP-1 생산은 CB 처리군에서 감소하는 경향을 보이고 COL 처리군에서는 변화되지 않았다. 5. CB처리군에서는 cytoskeletal actin stress fibers가 사라지고 세포모양이 둥글어지는 경향을 보였다. 이상의 결과로 미루어 보아 cytoskeletal rearrangement는 골모세포유사세포의 활성, 특히 $PGE_2$, IL-6, 및 TNF-$\alpha$같은 paracrine/autocrine factor의 생산과 관련있는 것으로 보인다.

  • 본 연구에서는 건조 고등어 추출물 및 분획물들에 의한 nitric oxide 생성에 미치는 영향을 살펴보았고 건조 고등어 85% aq. MeOH 분획물을 중심으로 면역과정의 생물학적 작용과 대사적 변화를 유도하는 IL-6, IFN-${\gamma}$ 및 TNF-${\alpha}$ 같은 pro-inflammatory 사이토카인의 생성을 측정하여 건조 고등어 추출물에 의한 항염증 효과에 대하여 검토하였다. 건조 고등어 추출물과 각 분획물은 control보다 낮은 nitric oxide 생성량을 나타내었으며, 특히 85% aq. MeOH 및 n-hexane 분획물에 의한 저해효과가 높았다. 건조 고등어 분획물은 Con-A 보다는 LPS에 의해 자극된 IL-6, TNF-${\alpha}$ 및 IFN-${\gamma}$의 생성을 감소시키는데 더 효과적이었다. IL-6 및 TNF-${\alpha}$의 생성은 배양시간 6시간 후 건조 고등어 85% aq. MeOH 분획물의 모든 첨가농도(1, 3 및 $10{\mu}g$)에서 감소되었다(p<0.05). IFN-${\gamma}$의 경우, 건조 고등어 85% aq. MeOH 분획물을 LPS와 함께 처리했을 때 특히 72시간 배양 시 IFN-${\gamma}$의 생성량이 농도 의존적으로 감소하였고 Con-A에 의해 자극된 IFN-${\gamma}$의 생성량은 6 및 24시간 배양 후 유의적으로 감소하였다(p<0.05). 이상의 결과로부터 건조 고등어 85% aq. MeOH 분획물은 nitric oxide 생성과 pro-inflammatory 사이토카인(IL-6, TNF-${\alpha}$, and IFN-${\gamma}$)을 감소시켜 염증반응을 예방할 것으로 기대된다.
