  • Moxibustion is one of major healing technique in oriental medicine. It has been widely used in many diseases such as rheumatoid arthritis, Hashimoto disease, breech presentation, etc. However, till now, effects of moxibustion on NK cell activity and relations between sympathetic nerve system(SNS) and the immune alteration induced by moxibustion were not well studied. This study was designed to evaluate effects of moxibustion on NK cell activity and the intervention of SNS in the alteration of NK cell activity induced by moxibustion. Splenic NK cytotoxity was measured in a standard 4-h 51Cr release assay. We measured the NK cytotoxity at after moxibustion stimulation for 1,3,5, and 7 days, and also measured the NK cell cytotoxity after 3 and 7 days burn stimulation with similar temperature. IL-2, IL-4, INF-γ in serum were measured by rat IL-2, IL-4, INF-γ ELISA TEST KIT. To evaluate the effects of sympathectomy on alteration of NK cell cytotoxity, 6-hydroxydopamine(6-OHDA : 5Omg/kg) was used. We showed that NK cell activity of moxibustion stimulation group increased at the 3rd day, and declined at 7th day in comparison with that of contol group. In moxibustion stimulation group, NK cell activity of 3 day stimulation group was significantly higher than sham group. On the contrary, in burn stimulation group, NK cell activity was significantly higher than that of sham groups at 3rd, 7th days. Patterns between moxibustion and burns were different. INF- γ level of 3 days moxibustion stimulation group significantly higher than sham group. IL 2 level among groups were not different. IL-4 was not detected in serum with this method. Sympathectomy abolished the NK cell activity alteration induced by moxibustion. The results suggest that moxibustion induces the alteration of NK cell activity, along with INF-γ and SNS is related to these effects.

  • Objectives : Gal-Geun-Tang (GT) has been described from SANGHAN in Korean traditional medicine and known to act against cold, fever, hypertension, and nasal catarrh. However, little has yet been learned about the effect of GT on immune function. In the current study, in vitro and in vivo immunomodulatory activity of GT (water extract) was investigated.Methods : Water extract of GT induced in vitro proliferation of spleen cells and significantly increased their proliferative responses during anti-CD3 activation. Using purified splenic T and B cells, it was revealed that GT has a mitogenic activity to B cells and promotes their proliferation induced by lipopolysaccharide, whereas T cell proliferation was not triggered and GT was rather inhibitory to T cell activation caused by anti-CD3 antibody. In the presence of antigen presenting cells (APC), GT addition resulted in a significant increase of IFNγ and IL-4, but not IL-2, production. However, addition of high concentration (1,000㎍/㎖) of GT led to a marked reduction in T cell cytokine production and under such condition, GT facilitated apoptosis of T cells when examined by flow cytometry with propidium iodide staining.Results : In vivo immunomdulation of GT was also investigated using a mouse model. Following keyhole limpet hemocyanin (KLH) immunization, GT (1 ㎎/day) was orally administered for 9 days. Cell numbers in thymus, spleen and peripheral blood were not altered by GT administration, indicating that such dose is not immunotoxic. Cell numbers in draining lymph nodes (LN) and ex vivo Ag-specific proliferation of LN cells were significantly elevated by GT administration. However, any preferential stimulation of T or B and CD4+ or CD8+ T cell subpopulations was not observed in a flow cytometric analysis of LN cells. This result shows that GT does not promote in vivo B cell proliferation while GT enhances Ag-specific proliferation of LN cells, unlike what was observed in vitro.Conclusions : For a further understanding of in vivo immunomodulatory activity of GT, ex vivo cytokine production of LN cells obtained from KLH-immunized mice was evaluated. Ag-specific IFNγ production was significantly higher in GT-treated mice when compared to PBS-treated control mice. In contrast, IL-4 production in GT-treated group was comparable to control group unlike to in vitro data. In addition, GT administration did not result in any significant differences in serum levels of Ig (IgM, IgG1 and IgG2a) between GT-treated and control groups. Taken together, these data strongly support that GT promotes immune response, more profoundly type 1 helper T cell (Th1) activity and GT may be applicable for treatment of intracellular parasite infection such as viral diseases.

  • Purpose: Immunization with Porphyromonas gingivalis heat shock protein 60 (PgHSP60) may have an immunoregulatory effect on atherogenesis. The aim of this study was to determine whether nasal immunization with a PgHSP60 peptide could reduce atherosclerotic plaque formation in apolipoprotein E knockout (ApoE KO) mice. Methods: Seven-week-old male ApoE KO mice were assigned to receive a normal diet, a Western diet, a Western diet and challenge with PgHSP60-derived peptide 14 (Pep14) or peptide 19 (Pep19), or a Western diet and immunization with Pep14 or Pep19 before challenge with Pep14 or Pep19. Results: Atherosclerotic plaques were significantly smaller in mice that received a Western diet with Pep14 nasal immunization than in mice that received a Western diet and no Pep14 immunization with or without Pep14 challenge. An immunoblot profile failed to detect serum reactivity to Pep14 in any of the study groups. Stimulation by either Pep14 or Pep19 strongly promoted the induction of CD4+CD25+ forkhead box P3 (FoxP3)+ human regulatory T cells (Tregs) in vitro. However, the expression of mouse splenic CD4+CD25+FoxP3+ Tregs was lower in the Pep14-immunized mice than in the Pep14-challenged or Pep19-immunized mice. Levels of serum interferon gamma (IFN-γ) and transforming growth factor beta were higher and levels of interleukin (IL) 10 were lower in the Pep14-immunized mice than in the other groups. Induction of CD25- IL-17+ T helper 17 (Th17) cells was attenuated in the Pep14-immunized mice. Conclusions: Nasal immunization with Pep14 may be a mechanism for attenuating atherogenesis by promoting the secretion of IFN-γ and/or suppressing Th17-mediated immunity.

  • Streptococcus agalactiae is an important bacterial pathogen and causative agent of diseases including neonatal sepsis and meningitis, as well as infections in healthy adults and pregnant women. Although antibiotic treatments effectively relieve symptoms, the emergence and transmission of multidrug-resistant strains indicate the need for an effective immunotherapy. Effector T helper (Th) 17 cells are a relatively newly discovered subpopulation of helper CD4+ T lymphocytes, and which, by expressing interleukin (IL)-17A, play crucial roles in host defenses against a variety of pathogens, including bacteria and viruses. However, whether S. agalactiae infection can induce the differentiation of CD4+ T cells into Th17 cells, and whether IL-17A can play an effective role against S. agalactiae infections, are still unclear. In this study, we analyzed the responses of CD4+ T cells and their defensive effects after S. agalactiae infection. The results showed that S. agalactiae infection induces not only the formation of Th1 cells expressing interferon (IFN)-γ, but also the differentiation of mouse splenic CD4+ T cells into Th17 cells, which highly express IL-17A. In addition, the bacterial load of S. agalactiae was significantly increased and decreased in organs as determined by antibody neutralization and IL-17A addition experiments, respectively. The results confirmed that IL-17A is required by the host to defend against S. agalactiae and that it plays an important role in effectively eliminating S. agalactiae. Our findings therefore prompt us to adopt effective methods to regulate the expression of IL-17A as a potent strategy for the prevention and treatment of S. agalactiae infection.

  • Background: The existing research results on the combined toxicity of these pollutants using mammals, such as rodents, are insufficient, especially in relation to changes in the immune system. Objectives: This study aims at evaluating the cellular immune response to PE-MPs solely or when combined with Pb, which possess excellent adsorption capacity with PE-MPs and is commonly co-exposed in our daily lives. Methods: The study investigated the cellular immune function of 9-week ICR mice with 28 days exposure to PE-MPs (2 mg/mouse/day) and Pb (0.1 mM in distilled water) individually and in combination. PE-MPs were administered via gastric intubation while the lead intake was conducted via the oral drinking water route. Cellular immunity was evaluated by analyzing the production for TH1 cytokines namely, TNF-α and IFN-𝛾 and TH2 cytokines, IL-4 and IL-6 in culture supernatants from polyclonally activated splenic mononuclear cells ex vivo. Results: Both the PE-MPs only and the PE-MPs+Pb exposure group revealed an increased TH1 response with elevated TNF-α and IFN-𝛾 levels and downregulated TH2 response with low IL-4, and IL-6 production levels compared to the control group. Furthermore, an increased IFN-𝛾/IL-4 ratio was found in the PE-MPs only and PE-MPs+Pb exposure groups, which indicated the skewedness to TH1 response. Meanwhile, reduced blood hemoglobin levels and increased levels of IL-4, the dominant TH2 cytokine in the Pb-only exposure group, were observed. Conclusions: Our current findings on the predominance of TH1 immune response in the PE-MPs and PE-MPs+Pb groups suggest that PE-MPs could be responsible for the predominant induction of the cellular immune changes. This finding could be used as an important landmark in research related to TH1 predominance, such as autoimmune diseases. It suggests that additional research on immune modulation using longer exposure durations or the same exposure route is required to elucidate stronger findings.

  • 연구배경 : 기관지 동맥색전술은 일시적 혹은 영구적인 지혈효과를 기대할 수 있고, 지혈효과이외에도 수술이 불가능한 환자나 수술이 필요한 환자의 경우에 수술전 환자상태를 호전시키기 위한 목적으로 이응퇴고 있다. 저자들은 대량객혈환자에서 동맥색전술의 효과 및 객혈의 재발율을 알아보고 재발된 환자의 임상적, 방사선학적 특징과 임상경과 및 예후를 조사하여 동맥색전술의 유용성을 평가해보고자 하였다. 그리고 색전술후에 재출혈이 일어나는 원인과 재발을 예측할 수 있는 인자를 알아보고자 하였다. 방법 : 객혈을 주소로 입원한 환자중 1회 100cc이상, 1일 500cc이상의 대량객혈로 동맥색 전술을 시행한 47명의 환자를 대상으로 의무기록과 혈관조영술 사진을 후향적으로 조사하였다. 결과 : 1)대량객혈의 원인질환으로는 폐결핵(35예), 기관지확장증(5예), 국균종(2예), 폐암(2예) 폐동정맥기형(1예)와 원인미상(2예)이 있었다. 2) 기관지 동맥색전술의 지혈성공율은 94%였으며, 추적관찰중 객혈의 재발은 40%였다. 3) 초기 기관지 동맥조영술 소견상 색전대상이 양측성인 경우, 체측부동맥-폐동맥간단락이 있는 경우, 기관지동맥이외의 체측부동맥이 영양동맥으로 관여한 경우와 과도한 신생혈관형성이 있었던 경우 등 이들 모두에서 재출혈군과 비재출혈군 사이에서 유의한 차이를 보이지 않았다. 4) 재색전술을 시행한 경우는 18예(13명)였다. 이들 중 14예(78%)에서 혈관의 재개통이 있었으며, 8예(44%)에서 초기에 색전하지 못하였던 혈관들의 과증식으로 인한 새로운 영양동맥의 형성에 의한 재출혈이 있었다. 5) 동맥색전술의 합병증은 발열, 흉통, 기침, 배뇨장애 등 경미한 합병증이 대부분(27예,87%)이었고, 마비성장폐색, 무기폐, 하반신마비, 비장경색 등 장기합병증이 각각 1예씩으로 13%를 차지하였다. 결론 : 기관지 동맥색전술은 대량객혈시 지혈율이 높고 심각한 합병증의 빈도가 적어 효과적이면서도 비교적 안전하게 시행할 수 있는 치료방법으로 사료된다. 대량객혈시 초기 기관지 동맥조영술 소견으로 색전술후 재발을 예측하기는 어려우며, 재출혈이 있는 경우 대부분의 원인은 이전 색전동맥의 재개통과 새로운 영양동맥의 형성이 관여함을 알 수 있었다.

  • 연구배경 : 대량 객혈은 내과적 혹은 외과적 치료로도 사망율이 매우 높은 임상증상이다. 대량 객혈은 높은 기관지 동맥 혹은 비기관지성 전신동맥에서 출혈된다고 알려져 있으므로, 최근 상기 혈관들을 색전시키는 것이 치료방법으로 되고 있으나 초기 색전후 일부에서 객혈이 재발되는 것이 문제로 되어 있다. 이에 저자들은 대량출혈환자에서 동맥색전을 하여 즉각적인 지혈정도를 알아보고, 즉시 지혈된 후 객혈이 재발되는 환자들의 임상소견 및 초기 동맥촬영소견을 조사하여 보았다. 방법 : 1988년 1월부터 1991년 7월까지 전부 21명의 환자에서 대량 객혈로 동맥색전술을 시행하였다. 환자 모두에서 대퇴통맥으로 경피하 삽관술을 하여 기관지동맥외에도 비기관지 전신동맥에 혈관촬영을 시행한 후, 병변부위의 혈관에 gelfoam pieces로 색전을 실시하였다. 이후 환자들을 추적관찰하면서 동맥색전술의 효과를 평가하였다. 결과 : 처음 동맥색전후 21명의 전환자에서 즉시 지혈은 성공하였다. 9명의 환자에서 출혈이 재발되었으며, 12예의 환자들에서는 객혈의 재발은 없었다. 합병증으로는 발열, 흉통, 기침, 배뇨 장애, 장마비, 하지마비 및 비장경색증등이 있었으며, 9명의 환자에서는 별 증상을 호소하지 않았다. 출혈이 재발된 환자중, 2명은 대량객혈로 사망하였고, 2명은 폐절제술을 시행받았으며, 4명은 매번 객혈이 재발시마다 반복적인 동맥색전술 혹은 내과적 보존치료를 받고 있다. 결론 : 재출혈의 가능성이 있기는 하지만, 동맥색전술은 대량 객혈환자에서 출혈을 비교적 빠르고 안전하게 멈출 수 있는 치료법이다. 또 수술적 치료가 불가능한 폐질환 환자에서 객혈이 재발시마다, 반복 시행하는 동맥색전술은 일단 급한 출혈을 막고 생명을 연장시키는 데에 도움을 주리라 사료된다.

  • 목적: 무비증 환자에서 높은 사망률을 보이는 침습성 세균 감염의 위험성은 잘 알려져 있으며 예방적 항생제 처방 및 특히 피막세균에 대한 예방접종이 강조된다. 최근 피막세균에 대한 국내 백신 영역에서 많은 변화가 있었으나 국내 무비증 소아청소년 환자의 현황과 침습성 세균 감염, 예방적 항생제 처방 및 예방접종의 실태에 관한 보고는 찾기 어렵다. 방법: 1997년 1월부터 2016년 12월까지 20년간 단일 3차 병원의 18세 이하 소아청소년 무비증 환자를 대상으로 후향적 의무기록 분석 기술 연구를 시행하였다. 결과: 총 213명의 소아청소년 무비증 환자 중 선천성 무비증은 114명(53.5%), 기능성 무비증은 58명(27.2%)이었으며 나머지 41명(19.3%)은 후천성 무비증이었다. 비장절제술을 받은 중앙 연령은 12.2세(범위, 5.0-16.9세)였으며 수술의 가장 흔한 원인은 유전구형적혈구증(39.0%)이었다. 전체 무비증환자 중 16.4%만이 1년 이상 예방적 항생제를 유지하였고 항균제는 amoxicillin이 94.3%로 가장 흔하였으며 유지기간 중앙값은 41개월(범위, 12-161개월)이었다. 전체 무비증 환자 중 168명(78.9%)에서 예방접종력을 확인할 수 있었으며, 각 피막세균에 대한 예방접종률은 폐렴사슬알균이 44.1%, b형 인플루엔자균(Haemophilus influenzae type B)은 53.0%, 수막알균은 10.7%로 낮았고 3가지 백신을 모두 완료한 환자는 8.7%에 불과하였다. 연구 기간 동안 총 6명에서 6예(2.8%, 0.28/100인년)의 침습성 세균 감염증이 발생하였고 5예는 선천성 무비증, 1예는 기능성 무비증군에서 발생하였으며 발생 중앙 연령은 15개월(범위, 4-68개월)이었다. 6예 중 5예는 균혈증, 1예는 뇌수막염이었고, 가장 흔한 균은 폐렴사슬알균(n=3)이었으며 그 외 H. influenzae가 1예 있었다. 6예 중 3예(50.0%)가 사망하였고 모두 폐렴사슬알균 균혈증이었다. 6예 모두 예방적 항생제를 처방받지 않았고 예방접종력을 확인할 수 있었던 4예 중 1예만 Hib의 접종을 완료하였으나 나머지 모두는 피막세균 예방접종을 전혀 받지 않았다. 결론: 무비증 환자에서 높은 사망률을 보이는 침습성 세균 감염의 위험은 전통적으로 잘 알려져 있음에도 불구하고 적절한 예방적 항생제 처방 및 필수 예방접종률은 여전히 낮은 수준이다. 따라서 임상 의사는 무비증 환자의 정기적 추적 관찰뿐만 아니라 적절한 예방적 항생제 및 필수 예방접종에 대해 숙지할 필요가 있다.
