Endometritis is one of the primary reasons for reproductive failure. In order to investigate endometritis-associated marker proteins, proteomic analysis was performed on bovine endometrium with endometritis. In bovine endometritis, desmin, $\alpha$-actin-2, heat-shock protein (HSP) 27, peroxiredoxin-6, luteinizing hormone receptor isoform 1, collectin-43 precursor, deoxyribonuclease-I (DNase-I), and MHC class I heavy chain (MHC-Ih) were up-regulated. In contrast, transferrin, interleukin-2 precursor, hemoglobin $\beta$ subunit, and potassium channel tetramerisation domaincontaining 11 (KCTD11) were down-regulated in comparison to normal endometrium. The proteomic results were validated by semiquantitative-PCR and immunoblot analysis. The mRNA levels of desmin, transferrin, $\alpha$-actin-2, HSP27, KCTD11, and MHC-Ih were up-regulated by over 1.5-fold, and showed a pattern similar to their proteomic profiles. Desmin and $\alpha$-actin-2 protein showed positive correlations between proteomic analysis and immunoblot analysis. These results suggest that desmin and $\alpha$-actin-2 may play important roles in endometritis-related function, and could be useful markers for the diagnosis of bovine endometritis.

형질전환 동물의 유선에서 특이적으로 발현되도록 고안된 pBIL-10 발현 벡터를 이용하여 인간 IL-10 유전자가 삽입되어 한 계통으로 확립된 형질전환 생쥐에서 이 유전자가 장기 세대까지 안정적으로 전이되고, 또한 발현 수준도 지속적으로 유지되는지를 조사하였다. 이를 위해 제 8 세대의 수컷 hIL-10 형질전환 생쥐를 실험에 공시하였고, 제 15 세대까지의 전이율과 hIL-10 유전자의 발현 수준을 분석하였다, 제 8 세대 생쥐의 계대 번식에 의한 자손 중 50.9±5.8％가 형질전환 생쥐로 판명되었다. 또한 제 9 세대에서 외래 유전자의 전이율은 66.0±20.1％이렀고, 제 10 세대에서 외래 유전자의 전이율은 61.5±16.7％이었고, 제 11 세대에서 외래 유전자의 전이율은 41.1±8.4％이었고, 제 12 세대에서 외래 유전자의 전이율은 40.7±20.3％이었고, 제 13 세대에서 외래 유전자의 전이율은 61.3±10.8％이었고, 제 14 세대에서 외래 유전자의 전이율은 49.2±18.8％이었고, 제 15 세대에서 외래 유전자의 전이율은 43.8±25.9％이었다. 이러한 결과로 hIL-10 형질전환 생쥐는 그 외래유전자의 유전적 손상이 없이 장기 세대까지 안정적으로 전이되는 것으로 판다된다. 제 9 세대의 암컷 형질전환 생쥐로부터 유즙내 인간 hIL-10의 발현 수준을 분석하였을 때, 그 농도는 평균 3.6± 1.2 mg/ml의 수준에서 측정되었다. 제 10세대에서는 유즙내 인간 hIL-10의 발현 수준을 분석하였을 때, 그 농도는 평균 4.2±0.9 mg/ml의 수준에서 측정되었고, 제 11세대에서는 유즙내 인간 hIL-10의 발현 수준을 분석하였을 때, 그 농도는 평균 5.7± 1.5 mg/ml의 수준에서 측정되었고, 제 12세대에서는 유즙내 인간 hIL-10의 발현 수준을 분석하였을 때, 그 농도는 평균 6.3±3.5 mg/ml의 수준으로 측정되었고, 제 13세대에서는 유즙내 인간 hIL-10의 발현 수준을 분석하였을 때, 그 농도는 평균 6.8±4.5 mg/ml의 수준으로 측정되었고, 제 14세대에서는 유즙내 인간 hIL-10의 발현 수준을 분석하였을 때, 그 농도는 평균 6.8±3.1 mg/ml의 수준으로 측정되었다. 이러한 수준은 제 1 세대의 것보다 높은 결과로 형질전환 생쥐에서 인간 IL-10 유전자의 발현은 최소한 15 세대까지 지속적으로 유지된다는 것을 알 수 있었으며, 장기 세대까지도 발현수준이 유지될 것으로 판단된다. 이러한 연구결과는 계통으로 확립된 형질전환 동물에 부여된 새로운 유전형질은 지속적으로 후대로 유전될 수 있음을 제시한다.

연구배경: 기관지천식은 호산구성 기도내 염증반응을 특징으로 하는데 호산구의 침윤에 관여하는 cytokine으로 T 림프구에서 분비되는 IL-3, IL-5, GM-CSF 등이 잘 알려져 있다. 한편 IL-10은 항염증성 cytokine으로 이러한 cytokine 분비를 억제할뿐만아니라, 호산구에 대해서는 직접적으로 자사(apoptosis)를 유도하고 조직내 첨착을 억제하는 기능을 갖고 있다. 본 연구에서는 기관지천식 환자에서의 기관지폐포세척액과 말초 혈액단핵세포에서 분비되는 IL-10을 정상대조군과 비교하고 기도내 염증반응정도와의 연관성을 분석하여 기관지천식에서의 IL-10 역할을 알아보고자 하였다. 방 법: 기관지천식환자 23명, 정상대조군 11명을 대상으로 기관지폐포세척액내와 말초혈액단핵구에서 분비되는 IL-10을 ELISA 방법으로 측정하고, 기도의 염증반응정도는 기관지세포세척액내 총세포수 및 호산구분율과 기관지 생검조직내 호산구 침윤정도, methacholine 기관지유발 검사에서 $PC_{20}$값으로 평가하였다. 결 과: 기관지폐포세척액내 IL-10과 말초혈액단핵구에서 분비되는 IL-10은 기관지천식 환자군과 정상대조군 사이에 통계적으로 유의한 차이는 없었다. 기관지천식환자군에서 기관지폐포세척액내 IL-10은 기관지폐포세척액내 호산구분율 및 기관지 조직내 침윤된 호산구수와는 유의한 역상관관계를 보였고, 메타콜린에 대한 PC20에 따른 차이는 없었다. 말초혈액단핵구에서 분비되는 IL-10은 기관지폐포세척액내 IL-10과 상관 관계가 없었으며, 말초혈액내 호산구수나 eosinophilic cationic protein과도 유의한 상관관계가 없었다. 결 론: 기관지천식 환자군의 기관지폐포세척액내 IL-10은 기관지폐포세척액이나 기관지 조직내 호산구 침윤과 역상관관계를 보였지만, 정상대조군과 비교해서 IL-10 감소가 관찰되지 않았기 때문에 기관지천식에서는 항염증 효과가 있는 IL-10이 중요하게 작용하지 않을 것으로 생각된다.

Cytokines that bind to and signal through the gp130 co-receptor subunit include interleukin (IL)-6, IL-11, oncostatin M (OSM), leukemia inhibitory factor (LIF), cardiotrophin-1 (CT-1), and ciliary neutrophic factor (CNTF). Apart from contributing to inflammation, gp130 signalling cytokines also function in the maintenance of bone homeostasis. Expression of each of these cytokines and their ligand-specific receptors is observed in bone and joint cells, and bone-active hormones and inflammatory cytokines regulate their expression. gp130 signalling cytokines have been shown to regulate the differentiation and activity of osteoblasts, osteoclasts and chondrocytes. Furthermore, cytokine and receptor specific gene-knockout mouse models have identified distinct roles for each of these cytokines in regulating bone resorption, bone formation and bone growth. This review will discuss the current models of paracrine and endocrine actions of gp130-signalling cytokines in bone remodelling and growth, as well as their impact in pathologic bone remodelling evident in periodontal disease, rheumatoid arthritis, spondylarthropathies and osteoarthritis.

Indirubin is the active ingredient of Danggui Longhui Wan, a mixture of plants that is used in traditional Chinese medicine to treat chronic diseases. In this study we investigated the anti-inflammatory effects of an indirubin derivative, indirubin-3’-monoxime-5-sulphonic acid (I3M-5S, $C_{16}H_{11}N_3O_5S$). We found that I3M-5S inhibits the production of various inflammatory mediators such as nitric oxide (NO) and prostaglandin $E_2$ ($PGE_2$) as well as inflammatory cytokines, tumor necrosis factor-${\alpha}$ and interleukin-6 in lipopolysaccharide (LPS) stimulated murine macrophage, RAW264.7 cells. In addition, the expression of inducible nitric oxide synthase and cyclooxygenase-2, which are essential enzymes to produce NO and $PGE_2$, respectively, was blocked by I3M-5S treatment in LPS-stimulated RAW264.7 cells. Present data suggest that I3M-5S exhibits potent anti-inflammatory activity in cultured macrophages and merit further study as potential therapeutic agents for inflammatory disorders.

In previous studies, heat shock has been reported to induce the apoptosis or programmed cell death through the activation of caspase-3. 1 investigated the effect of juniper pure essential oil on the heat shock-induced apoptosis in human astrocyte cell line CCF-STTGI. Treatment of the astrocytes with heat shock markedly induced apoptotic cell death. However, pretreatment of the astrocytes with juniper oil ingibited the heat shock-induced apoptosis. To determine whether juniper inhibits the heat shock-induced activation of these apoptotic proteases, activation of CPP32 was assessed by Western blotting. Consistent with flow cytometry. DNA fragmentation and giemsa staining, heat shock-induced activation of CPP32 was blocked by juniper oil. Poly(ADP-ribose) polymerase (PARP), cysteine protease substrates were fragmented as a consequence of apoptosis by heat shock. Juniper oil inhibited the PARP fragmentation. This juniper oil also inhibited the heat shock-induced activation of caspase-3. These results suggest that juniper oil may modulate the apoptosis through the activation of the interleukin-1-converting enzyme-like protease.

Cardiopulmonary bypass (CPB) for cardiac surgery induces the production and release of numerous chemotactic substances and cytokines, ensuing systemic inflammatory response that causes postoperative major organ dysfunctions. We performed a randomized, prospective study to investigate clinical effects of preoperative treated-methylprednisolone for preventing inflammation in pediatric cardiac surgery with CPB. Thirty pediatric patients scheduled for elective cardiac surgery were randomized to either control(n=15) or steroid group (n=15, 10 mg/kg of methylprednisolone). Arterial blood samples were taken before and after the operations for measuring total leukocyte (T-WBC) and differential counts, platelet counts, interleukin-6 (IL-6), myeloperoxidase (MPO), neuron specific enolase (NSE), troponin-I (TNI), aspartate aminotransferase (AST), alanine aminotransferase (ALT), blood urea nitrogen (BUN), and creatinine levels. Postoperative parameters such as pulmonary index (PI, $PaO_2/FiO_2$), 24 hrs and total bleeding volumes, mechanical ventilating (MVP) and intensive care unit (ICU)-staying periods, and hospitalization were assessed. T-WBC, neutrophil fraction, IL-6, MPO, NSE, TNI, AST and creatinine levels, bleeding volumes, PI, and MVP at the postoperative periods were lower or shorter in steroid group than in control group (P<0.05). These findings indicated that preoperative administration of methylprednisolone attenuated CPB-induced inflammatory reactions, contributing to postoperative recovery of patients underwent cardiac surgery.

Objectives The purpose of this study is to investigate recent clinical studies on the effect of acupuncture for urticaria worldwide. Methods Based on the PubMed search with the key search terms of 'urticaria, acupuncture', dated between 2002 to 2015, a total of 9 randomized controlled trials (RCTs), 3 case series, and 2 case reports have been found, and were analyzed. Results and conclusions 1. The most commonly used acupoints were Quchi (LI 11), Xuehai (SP 10), Zusanli (ST 36), Sanyinjiao (SP 6), Dazhui (GV 14). 2. The most commonly used meridians were The Ren Channel, The Du Channel and The Gall Bladder Meridian of Foot-Shaoyang. 3. The treatment period varied from 12 days to 3 months. 4. Acupuncture treatment found to be significantly more or equally effective than the western medicine. 5. More clinical studies are needed to prove a true effectiveness of the acupuncture for urticaria. In case of laboratory tests, serum immunoglobulin E (IgE), interleukin 4 (IL-4) and Helicobacter pylori negative rate might be helpful.

A comprehensive study on the production of inflammatory mediators in the lungs of BALB/c mice following infection with Stenotrophomonas maltophilia was conducted. The levels of pro-inflammatory cytokines, tumor necrosis factor alpha (TNF-${\alpha}$), and interleukin-1${\beta}$ (IL-1${\beta}$) were raised in the lungs of infected mice compared with control. The production of anti-inflammatory cytokine IL-10 was slightly delayed. Its peak level was on the $2^{nd}$ day, whereas the peak of pro-inflammatory cytokines was observed on day 1 after intranasal challenge. This was accompanied by a rise in myeloperoxidase (MPO) and malondialdehyde (MDA) on day 1. The increase in MPO levels matched with histopathological observations, as neutrophils infiltration was detected on the first day. Alveolar macrophages (AMs) obtained from infected animals showed a higher rate of uptake and killing when exposed to bacteria in vitro, compared with similar experiments conducted with AMs from normal mice (control). This suggests that AMs were more efficient in cleaning the bacteria. The nitric oxide (NO) production however started early during infection but reached its maximum on the $3^{rd}$ day. No mortality was observed among the infected animals, and infection was resolved by the $5^{th}$ day post infection. No drastic changes in the lung tissue were observed on histopathological examination.

Cirsium japonicum var. ussuriense is known to have a variety of biological activities, including anti-inflammatory, analgesic activity and antipyretic activity. In this study we investigated the role of polyacetylene compound, 1-Heptadecene-11, 13-diyne-8, 9, 10-triol (PA) from the root of Cirsium japonicum var. ussuriense as an immune-modulator. PA was evaluated as inhibitors of some macrophage functions involved in the inflammatory process. We tested the effect of PA on the production of pro-inflammatory cytokines, interleukin-1beta (IL-$1{\beta}$) and tumor necrosis factor-alpha (TNF-$\alpha$), and nitric oxide (NO) in murine macrophage cell line, RAW264.7. There was no effect on cytokine production of macrophages by PA itself. However, PA inhibited lipopolysaccharide (LPS)-induced IL-$1{\beta}$ and TNF-$\alpha$ production by macrophages at a dose dependent manner. PA also suppressed the NO production of macrophages by LPS. LPS-induced NF-${\kappa}B$ activity was decreased by treatment of PA. Therefore, these results suggest that PA has anti-inflammatory effect by inhibiting the NF-${\kappa}B$ activation.
