Aster Yomena (AY) has been used in traditional medicine to treat diseases such as obesity, hyperlipidemia, atherosclerosis, diabetes and osteoarthritis. However, protective effect of AY on acute pancreatitis (AP) has not been reported. The present study examined the anti-inflammatory effects of an ethanol extract of AY on cerulein-induced AP. AP was induced in mice by intraperitoneally injecting cerulein ($50{\mu}g/kg$) hourly for 6 times. 70% ethanol extract of AY (0.1, 0.2, and 0.5 g/kg) was orally administered for 1 week before acute pancreatitis induction. The mouse was killed at 6 hours after the final cerulein injection. The pancreas and lung were rapidly removed for histological examination and myeloperoxidase (MPO) assay. Blood samples were taken to determine serum amylase and lipase activity. In addition real-time reverse transcription-polymerase chain reaction (RT-PCR) was also performed to investigate mRNA expression of proinflammatory cytokines such as $TNF-{\alpha}$. $IL-1{\beta}$, and IL-6. Administration of AY significantly ameliorated pancreatic weight to body weight ratio, histological damages and MPO activity during AP. In addition, AY inhibited the serum amylase and lipase activity during AP. Also, mRNA expression of $TNF-{\alpha}$, $IL-1{\beta}$ and IL-6 were inhibited by AY against AP. Our results revealed that pre-treatment of AY reduces the severity of cerulein-induced AP. Therefore, AY may have a protective effect drug against AP.

Objectives : Smilacis Glabrae Rhizoma (SGR) has been used in traditional medicine for treating diseases related to inflammation and cancer. However, the protective effect of SGR has not been reported in the study of acute pancreatitis (AP). Therefore, this study was performed to evaluate the protective effects of SGR water extract on cerulein-induced AP. Methods : AP was induced by intraperitoneal injection of supramaximal concentrations of stable cholecystokinin analogue cerulein ($50{\mu}g/kg$) 6 times at intervals of one hour in mice. SGR water extract (0.01, 0.05, or 0.1 g/kg) was administrated intraperitoneally 1 h prior to the first injection of cerulein. The mice were sacrificed at 6 h after the final injection of cerulein. Pancreas and lung were rapidly removed for histochemical examination and myeloperoxidase (MPO) assay. In addition, polymerase chain reaction (PCR) was performed to examine mRNA levels of proinflammatory cytokines such as interleukin(IL)-6, $IL-1{\beta}$ and Tumor necrosis $factor(TNF)-{\alpha}$. Results : Administration of SGR water extract significantly inhibited pancreatic weight to body weight ratio. In addition, SGR treatment inhibited the histological damages and increase of MPO activity in both pancreas and lung during AP. Also, mRNA levels of IL-6 but not $IL-1{\beta}$and $TNF-{\alpha}$ were inhibited by SGR water extract against AP. Conclusion : Our results revealed that pre-treatment of SGR water extract reduces the severity of cerulein-induced AP. Therefore, this study suggest that SGR could be used as a drug or agent to prevent AP.

To investigate the neuroprotective effects of bovine colostrums (BC), we evaluate the ability of consuming BC after focal brain ischemia/reperfusion injury rat model to reduce serum cytokine levels and infarct volume, and improve neurological outcome. Sprague-Dawley rats were randomly divided into 4 groups; one sham operation and three experimental groups. In the experimental groups, MCA occlusion (2 h) and subsequent reperfusion (O/R) were induced with regional cerebral blood flow monitoring. One hour after MCAO/R and once daily during the experiment, the experimental group received BC while the other groups received 0.9% saline or low fat milk (LFM) orally. Seven days later, serum pro-inflammatory cytokine (IL-$1{\beta}$, IL-6, and TNF-${\alpha}$) and anti-inflammatory cytokine (IL-10) levels were assessed. Also, the infarct volume was assessed by using a computerized image analysis system. Behavioral function was also assessed using a modified neurologic severity score and corner turn test during the experiment. Rats receiving BC after focal brain I/R showed a significant reduction (-26%/-22%) in infarct volume compared to LFM/saline rats, respectively (P < 0.05). Serum IL-$1{\beta}$, IL-6, and TNF-${\alpha}$ levels were decreased significantly in rats receiving BC compared to LFM/saline rats (P < 0.05). In behavioral tests, daily BC intake showed consistent and significant improvement of neurological deficits for 7 days after MCAO/R. BC ingestion after focal brain ischemia/reperfusion injury may prevent brain injury by reducing serum pro-inflammatory cytokine levels and brain infarct volume in a rat model.

The stem-bark of Kalopanax pictus (KP, family Araliaceae), of which main constituent is kalopanaxsaponin B, has been used for asthma, rhinitis, and arthritis in Chinese traditional medicine. To clarify anticolitic effect of KP, we examined anti-inflammatory effect of KP extract and kalopanaxsaponin B in lipopolysaccharide (LPS)-stimulated peritoneal macrophage and 2,4,6-trinitrobenzene sulfonic acid (TNBS)-induced colitic mice. Of KP extracts, KP BuOH-soluble fraction most potently inhibited LPS-induced IL-$1{\beta}$, IL-6 and TNF-${\alpha}$ expression, as well as NF-${\kappa}B$ activation. However, KP BuOH fraction increased IL-10, an anti-inflammatory cytokine. KP BuOH fraction also inhibited colon shortening and myeloperoxidase activity in TNBS-induced colitic mice. KP BuOH fraction also potently inhibited the expression of the pro-inflammatory cytokines, IL-$1{\beta}$, IL-6, and TNF-${\alpha}$ as well as the activation of NF-${\kappa}B$. Kalopanaxsaponin B, a main constituent of KP, inhibited TNBS-induced colonic inflammation, including colon shortening, and TNBS-increased myeloperoxidase activity pro-inflammatory cytokine expression and NF-${\kappa}B$ activation in mice. Based on these findings, KP, particularly its main constituent, kalopanaxsaponin B, may ameliorate colitis by inhibiting NF-${\kappa}B$ pathway.

Objectives This study was aimed to investigate the effects of Sibjeondaebotanggamibang (SJT) on the wound-induced rats. Methods It was observed the effects of anti-oxidation and anti-inflammation by using of lipopolysaccharide (LPS)-treated RAW 264.7 cells. For the observing on SJT anti-oxidation, it needed to mesure the total amount of polyphenol, DPPH scavenging ability, ABTS scavenging ability and the value of ROS production. In order to observe on the anti-inflammation of SJT, it was mesured the value of No and Cytokine (TNF-${\alpha}$, IL-$1{\beta}$, IL-6). It needed to make a scar (around $2{\times}2cm^2$) on the top of the fascia in the back of the rats and then the rats were divided into 4 groups (n=6). Control group was not treated at all, whereas SJ group was orally medicated SJT, Terra group was per-cutaneously applied Terramycin, and SJ+Terra group was both orally medicated SJT and percutaneously applied Terramycin per day for three weeks. The size of wound was measured with Digimatic Caliper and the blood samples (WBC, neutrophil, monocyte, lymphocyte) were analyzed using Minos-ST, which were collected by cardiac puncture. The effect on inflammatory cytokine (TNF-${\alpha}$, IL-$1{\beta}$, IL-6), immunological cells in synovial fluid was measured. To measure the wound factor expressed by wounded skin sample, we extracted RNA and to investigate MMP-1,2,9 we used RT-PCR. For performing histopathological examinations, we paralyzed the rats by ether, and extracted wounded skin tissues, which were measured by H & E, and monitored on the optical microscope. Results 1. DPPH and ABTS scavenging activity of SJT was increased concentration-dependantly, and ROS scavenging activity was significantly increased (10, $100{\mu}g/ml$). 2. NO production was significantly reduced in SJT treated cells ($100{\mu}g/ml$), both TNF-${\alpha}$ and IL-6 in SJT treated cells (1, 10, $100{\mu}g/ml$), and IL-$1{\beta}$ in SJT treated cells (1, $100{\mu}g/ml$). 1. The size of wound was significantly decreasing in SJ group, Terra group, SJ+Terra group. 2. WBC was significantly reduced in SJ and SJ+Terra group, monocyte in SJ+Terra group. Neutrophil was also reduced in SJ, SJ+Terra group but meaningless. 3. TNF-${\alpha}$ and IL-6 were significantly reduced in SJ group, Terra group, SJ+Terra group, and IL-$1{\beta}$ in SJ+Terra group. 4. mRNA expression in MMP-1 was significantly reduced in SJ group. 5. Collegan production and chronic inflammation were significantly decreased in SJ group, Terra group, SJ+Terra groups. Re-epithelization on the skin in Terra group, SJ+Terra groups was decreased. Conclusions According to this in vitro experiment, Sibjeondaebotanggamibang (SJT) has the effects of anti-oxidative and anti-inflammatory. By in vivo experiment, SJT has the effects of anti-inflammatory. Moreover, the progress of recovery was found visually, heamatologically, genetically and histopathologically. In conclusion, it could be thought that SJT has effect on the treating of wound.

배경 : 급성 폐손상은 폐내, 외의 원인질환들에 의해 폐포-모세혈관의 투과성이 증가하며, 폐부종에 의해 급성 저산소성 호흡곤란이 유발되는 증후군이다. 헤파린은 항응고작용 외에 자체적으로 항염증효과를 가지고 있으나, 염증성질환에 헤파린을 투여하면 출혈성 합병증이 발생하기 때문에 실제로 임상에서 이용하는데 제약이 있다. 하지만 헤파린에서 2-O와 3-O sulfate를 제거하면, 항응고 효과가 제거되고 항염증효과는 지니고 있는 비항응고성 헤파린 (nonanticoagulant heparin)으로 변화한다. 본 연구에서는 흰쥐에게 내독소 (LPS)를 투여하거나, 출혈성 쇼크를 일으켜서 유발된 급성폐손상에서 비항응고성 헤파린의 치료효과를 살펴보았다. 방법 : 각 군당 5 마리 이상의 흰쥐 (Balb/c mouse)를 이용하였다. 미정맥 (tail vein)을 통해 생리식염수 또는 비항응고성 헤파린 (50 mg/kg)을 투여한 직후에 내독소를 복강으로 투여하거나 (1 mg/kg), 심장천자를 통해 총 혈액의 1/3 정도로 제거하여 출혈성 쇼크를 유도하여 급성폐손상을 유발하였다. 내독소 투여 또는 출혈성 쇼크 유발 1 시간 후에 흰쥐를 희생시키고 폐를 적출하였고, 폐의 염증성 변화는 사이토카인 ($TNF-{\alpha}$, MIP-2, $IL-1{\beta}$)을 측정하여 살펴보았고, 폐손상의 정도는 myeloperoxidase (MPO) assay와 wet-to-dry weight ratio를 측정하여 알아보았다. 결 과 : 내독소를 투여한 흰쥐의 폐에서 대조군의 폐에 비해 사이토카인의 발현이 증가하고 ($TNF-{\alpha}$; $196.1{\pm}10.8$ vs $83.7{\pm}18.4pg/ml$, MIP-2; $3,000{\pm}725$ vs $187{\pm}26pg/ml$, $IL-1{\beta}$; $6,500{\pm}1167$ vs $266{\pm}25pg/ml$, p<0.05, respectively), 폐의 MPO 활성이 증가하였다 ($27.9{\pm}6.2$ vs $10.5{\pm}2.3U/g$ of lung protein, p<0.05). 출혈성 쇼크를 일으킨 흰쥐의 폐에서 대조군의 폐에 비해 사이토카인의 발현은 증가되지 않았으나, MPO 발현은 증가되었다 ($16.5{\pm}3.2$ vs $10.5{\pm}2.3U/g$ of lung protein, p<0.05). 내독소 투여 또는 출혈성 쇼크에 의해 급성폐손상이 유발된 흰쥐에서 생리적 식염수를 투여하거나 비항응고성 헤파린을 투여한 군 사이에 사이토카인의 발현이나 MPO 활성에 의미있는 차이는 관찰되지 않았다. 결론 : 이상의 결과로 비항응고성 헤파린은 내독소를 투여하거나 출혈성 쇼크를 일으키고 한 시간 뒤에 측정한 흰쥐의 급성폐손상에서 의미있는 치료효과를 보이지 않았다.

Sphingosine kinase 1 and its product, sphingosine 1-phosphate (S1P), as well as their receptors, have been implicated in inflammatory responses. The functions of receptors $S1P_1$ and $S1P_2$ on cell motility have been investigated. However, the function of $S1P_3$ has been poorly investigated. In this study, the roles of $S1P_3$ on inflammatory response were investigated in primary peritoneal macrophages. $S1P_3$ receptor was induced along with sphingosine kinase 1 by stimulation of lipopolysaccharide (LPS). LPS treatment induced inflammatory genes, such iNOS, COX-2, $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$. TY52156, an antagonist of $S1P_3$ suppressed the induction of inflammatory genes in a concentration dependent manner. Suppression of iNOS and COX-2 induction was further confirmed by western blotting and NO measurement. Suppression of $IL-1{\beta}$ induction was also confirmed by western blotting and ELISA. Caspase 1, which is responsible for $IL-1{\beta}$ production, was similarly induced by LPS and suppressed by TY52156. Therefore, we have shown $S1P_3$ induction in the inflammatory conditions and its pro-inflammatory roles. Targeting $S1P_3$ might be a strategy for regulating inflammatory diseases.

1,2,3,4,6-Penta-O-galloyl-${\beta}$-D-glucose(PGG)는 오배자(Galla Rhois)의 gallotannin으로 항산화 효과, 항균 효과, 항알레르기 효과 등을 가지는 것으로 알려졌다. 알레르기성질환은 비만세포를 포함한 다양한 면역세포와 관련된 질환이다. 비만세포는 탈과립화에 의한 알레르기 매개성 물질(histamine 및 ${\beta}-hexosaminidase$)의 분비, T helper 2 type 사이토카인(IL-4) 분비 및 염증을 일으키는 매개체($TNF-{\alpha}$)의 증가를 통해 알레르기 반응에서 중요한 역할을 한다. 따라서 본 연구에서는 PGG가 phorbol 12-myristate 13-acetate(PMA)와 A23187로 비만세포인 RBL-2H3 세포에서 탈과립 그리고 Th2 type 및 염증성 사이토카인 생산에 미치는 영향을 조사하고, 관련 메커니즘에 대해 평가하였다. PGG는 PMA와 A23187 자극에 의한 탈과립 마커(histamine 및 ${\beta}-hexosaminidase$)의 분비를 억제하고, IL-4 및 $TNF-{\alpha}$와 같은 사이토카인의 분비를 억제하였다. 이러한 효과는 전사인자인 $NF-{\kappa}B$의 세포질에서 핵으로의 이동을 억제함으로써 나타나는 것으로 판단된다. 이러한 결과로부터 gallotannin의 하나인 PGG가 알레르기 반응을 현저히 저해하는 효과가 있는 것으로 나타나, 향후 알레르기성 질환을 예방, 개선 및 치료하는 데 유용한 물질로 사용될 가능성이 있을 것으로 생각된다.

그람 음성균의 감염에 의한 만성 염증질환인 치주염이 동맥경화를 동반한 허혈성 심장질환 (협심증이나 심근 경색)을 일으킬 수 있는 위험인자로 작용할 수 있다는 보고가 있었다. 그러나, 그 기전에 관해서는 명확하게 알려져 있지 않다. 작용기전의 하나로서, 치주염에 의해 치주조직에서 국소적으로 생긴 염증성 싸이토카인(IL-1${\beta}$, IL-6, $PGE_2$, TNF-${\alpha}$)이 혈행을 따라 이동하여 심혈관에서 동맥경화를 일으킬 수 있다는 가설이 제시되고 있는데, 이 가설을 검증해 보고자 한다. 서울대학교 병원 순환기 내과에 불안정 협심증이나 심근경색으로 입원한 환자 및 과거 이 질환의 병력을 갖고 있거나 검진 목적으로 내원하여 관상동맥 조형술을 받은 환자들 중 동맥경화로 진단받은 사람을 실험군(24명)으로 하고, 동맥경화로 진단받지 않은 사람을 대조군(12명)으로 하였다. 치주질환의 활성도를 나타내는 치은 지수, 치태 지수, 치주낭 깊이, 부착 상실을 측정하였다. Paper strip을 실험대상 치아(Ramfjord's teeth)들 중에서 가장 깊은 치주낭을 가진 두 개의 치아를 택하여 각 치아의 가장 깊은 치주낭에 30초간 삽입한 후 밀폐된 plastic tube에 넣고 ELISA kit를 이용하여 IL-1${\beta}$, IL-6, TNF-${\alpha}$, $PGE_2$의 농도를 측정하였다. 환자의 plasma에서도 동일한 싸이토카인의 농도를 측정하였다. 설문조사를 통해 동맥경화의 위험 인자로 간주되어온 고혈압, 당뇨, 가족력, 심근경색이나 협심증의 기왕력, 흡연의 유무를 기록하였다. 혈액검사를 하여 total cholesterol, triglycerides, LDL cholesterol, HDL cholesterol, WBC, CRP (C-reactive protein)의 농도를 측정하였다. 치주조직에 대한 임상 검사 결과 치은의 염증상태를 나타나는 지표인 치은 지수에서만 실험군이 대조군에 비해 유의할 정도 (p=0.0174)로 높게 나타났고, 만성적인 염증의 결과로 인한 치조골의 사실 정도를 나타내는 치주낭 깊이나 부착 상실에서는 유의할 만한 차이를 보이지 않았다. 치주낭에서 측정한 염증성 싸이토카인 중 IL-1${\beta}$, $PGE_2$가 실험군에서 유의할 만한 차이 (p=0.005, 0.022)를 보이며, 더 높은 농도로 나타났고, TNF-${\alpha}$는 대조군에서 유의성 있게 (p=0.009) 높게 나타났다. 그러나, plasma의 싸이토카인이나, serum lipid/lipoprotein, C-reactive Protein, WBC는 유의할 만한 차이를 보이지 않았다. 또한 치은열구액내의 싸이토카인과 이에 상흥하는 싸이토카인 간에 상관관계는 관찰되지 않았다. 다변량 로지스틱 회귀분석 결과, 치은열구액내의 IL-1${\beta}$와 TNF-${\alpha}$ 만이 동맥경화와 유의성 있는 관련성을 보였고, 특히 IL-1${\beta}$와 교차비는 273으로 상당한 관련성을 보여주었다. 결론적으로, 치주조직에서 국소적으로 생긴 염증성 싸이토카인이 그대로 혈행으로 이동하여 혈장내의 싸이토카인 농도를 높이는 것은 아니다. 그러나, 치주염으로 인해 치은열구내액내에 국소적으로 증가된 염증성 싸이토카인은 동맥경화와 상당한 관련성을 가진다.
