Objectives : This study was carried out to investigate the effects of Samgi-eum(Sanqi-yin) on the monosodium iodoacetate-induced osteoarthritis in rats. Methods : Osteoarthritis was induced by injection of monosodium iodoacetate intraarticularly in both knee joints. Arthritic rats were divided into control and treated group. Control group were taken distilled water for 20days. Treated group were taken extracts of Samgi-eum(Sanqi-yin) by orally for the same duration. Normal group were injected normal saline and taken distilled water. Body weights were measured at 0, 5th, 10th, 15th, 20th day after injection. At the end of the experiment, gross and histopathological examination on the articular cartilages of the knee joints were performed. Proteoglycan contents of articular cartilages were analyzed by safranine O staining method. The contents of TNF-α, IL-1β and IL-6 in synovial fluids were analyzed by ELISA method. Results : 1. Body weights of the treated group were significantly increased compared with control at 20days after injection. 2. Grossly, the severity of osteoarthritis in the treated group were alleviated compared with control. 3. Histopathologically, degenerative and necrotic lesion of articular cartilages in the treated group were alleviated compared with those of the control and histopathological scores of treated group were significantly decreased compared with control. 4. PG contents in articular cartilages of the treated group were significantly increased compared with control. 5. TNF-α contents in synovial fluids of the treated group were significantly decreased compared with control. Conclusions : According to above results, Samgi-eum(Sanqi-yin) has anti-arthritic effects on the monosodium iodoacetate-induced osteoarthritis in rats. And it is related with reduced secretion of TNF-α from osteoarthritic chondrocytes and synovial membranes.

The aim of this study was to examine the efficacy of in ovo prime-boost vaccination against infectious bursal disease virus (IBDV) using a DNA vaccine to prime in ovo followed by a killed-vaccine boost post hatching. In addition, the adjuvant effects of plasmid-encoded chicken interleukin-2 and chicken interferon-γ were tested in conjunction with the vaccine. A plasmid DNA vaccine (pcDNA-VP243) encoding the VP2, VP4, and VP3 proteins of the very virulent IBDV (vvIBDV) SH/92 strain was injected into the amniotic sac alone or in combination with a plasmid encoding chicken IL-2 (ChIL-2) or chicken IFN-γ (ChIFN-γ) at embryonation day 18, followed by an intramuscular injection of a commercial killed IBD vaccine at 1 week of age. The chickens were orally challenged with the vvIBDV SH/92 strain at 3 weeks of age and observed for 10 days. In ovo DNA immunization followed by a killedvaccine boost provided significantly better immunity than the other options. No mortality was observed in this group after a challenge with the vvIBDV. The prime-boost strategy was moderately effective against bursal damage, which was measured by the bursa weight/body weight ratio, the presence of IBDV RNA, and the bursal lesion score. In ovo DNA vaccination with no boost did not provide sufficient immunity, and the addition of ChIL-2 or ChIFN-γ did not enhance protective immunity. In the ConA-induced lymphocyte proliferation assay of peripheral blood lymphocyte collected 10 days post-challenge, there was greater proliferation responses in the DNA vaccine plus boost and DNA vaccine with ChIL-2 plus boost groups compared to the other groups. These findings suggest that priming with DNA vaccine and boosting with killed vaccine is an effective strategy for protecting chickens against vvIBDV.

The purpose of this paper is to highlight, with the help of the Jumma community, a refugee community in Korea, the way in which the immigrant community is affected by the combination of the two factors, the adaptibility of the immigrants and the receptibility of Korean society. The main argument is to identify the fact that the components of the pre-state identities, which detonates the refugeefication, lead the internal differentiation of the refugee community due to the refugee’s strategy of adaptation, on the one hadn, and the characteristics of supporting organizations of the protection states, on the other. In this paper, first, the special aspects of refugees in their development are investigated, and, second, the Jumma community’s effort to keep their pre-state identities and the formative process of the Jumma community in Korea are evaluated. Thu authors identify the phenomenon of differentiation among refugees through the relationship with the supporting organizations in Korea. This division process of the refugee community possibly accelerates the dissolution and break-up of immigrant community. For this reason, the systematic management of refugees is also required. The outcome of this research includes: first, the immigrant community, which has been assumed as the united and homogeneous community, is internally evolved to different directions; second, the evolution of the immigrant community is led or strengthened by the supporting organizations in Korea which is relate to their own interests; third, the research on refugees, which has been alienated in the immigration and multiculturalsim studies for a long time, is evoked loudly; the importance of religion for the refugees’ adaptation process to the protecting country; last but not least, the Korean society is asked for its multicultural receptive policies to respect the tradition of the immigrant community and to manage their internal differentiation.

Neuropeptide Y(NPY) was first isolated from porcine brain. This discovery has lead some workers to study the distribution of this peptide in the central nervous system of various mammals. In this study the distribution pattern of neuropeptide Y-immunoreactive neurons was examined in the hippocampal complex of Striped field mouse in Korea(Apodemus agrarius coreae) Experimental animals were anesthesized with thiopental sodium and perfused with 4% paraformaldehyde through the left ventricle and the ascending aorta. The brains were removed and transferred 10%, 20% and 30% sucrose solution. Sections were cut on a cryostat into 40㎛-thick. The tissue was immunostained with free-floating and avidin-biotm complex(ABC) method. The results obtained in this study were summarized as followings. 1. The most of NPY-IR neurons in hippocampus proper were found in the polymorphic layer and a few was found in the pyramidal layer. 2. The process run vertically in the deep polymorphic layer and run parallel to corpus callosum in superficial polymorphic layer. 3. The shapes of neurons in hippocampus proper were varied of polymorphic, oval or round, and the nerve fibers were found in the molecular laver and the hippocampal fissure. 4. The highest density in number of NPY-IR neurons on dentate gyrus were found in hilar area of dentate gyrus. 5. The most of NPY-IR nerve fibers were found in molecular cell layer.

To investigate the effect of high dose irradiation on the Vickers hardness number(VHN), color change and wear rate of dental filling materials, esthetic filling material specimens were studied. Six kinds of composite resins and two kinds of glass ionomers(GI) were used. One(CLF) was chemically cured composite resin, and five(HCX, HPL, PHB, POF, PRT and RZI) were light cured composite resins. One(FJT) of GI was chemically cured GI and one(FLC) was light cured GI. The filling material specimens were made according to the manufacture's instructions and were finally polished with Microcloth(Buehler). Half of the specimens were irradiated with 100 Gy radiation using a linear accelerator(Mitsubishi, 6 MV). VHN and CIELAB color were measured before and after irradiation, and wear test were performed for nonirradiated specimens by brushing with toothpaste, From the experiment , the following results were obtained. 1. The CIELAB color difference was significantly different depending on the material(p<0.01), and FLC showed the highest color difference (CIELAB ΔE) of 9.452 and CLF showed the lowest value of 3.642. 2. The VHNs of nonirradiated specimens were 12.22∼73.58 and those of irradiated specimens were 25.53∼84.53. The VHNs of irradiated specimens were significantly higher than those of nonirradiated specimens(p<0.05) except RZI, FJT and FLC. 3. The wear rate of irradiated specimens of RZI, FLC were significantly lower than those of nonirradiated specimens(p<0.05). 4. The color difference after brushing of irradiated specimens were higher than those of nonirradiated specimens except CLF.

Eui-Baek Byun,Jeong Moo Han,Kwang-Il Kim 한국식품영양과학회 2021 한국식품영양과학회 학술대회발표집 Vol.2021 No.10

Dendritic cells (DCs) as professional antigen-presenting cells are used to assess adjuvants, in particular the evaluation the adjuvant selection of various vaccine platforms. Polysaccharides derived from Chrysanthemum zawadskii Herbich var. latilobum leaves (CP) was to demonstrate the immunostimulatory effect and assess its potent vaccine djuvant candidate. Results showed that CP induced maturation of the dendritic cells (DCs). In addition, CP-treated DCs activated naïve T cells to polarized CD4+ and CD8+ T cells and substantially induced the production of IFN-γ and IL-2 in vitro. Furthermore, CP initiated the maturation of DCs via the activation of MAPK and NF-κB signaling pathways. Interestingly, systemic administration of CP-treated DCs pulsed with ovalbumin (OVA) peptides significantly enhanced the immune response in vivo, which included the generation of antigen (OVA)-specific polyfunctional T cells, increased cytotoxic T lymphocyte activity, induction of Th1-mediated humoral immunity, and suppression of tumor growth. From these results, our study provided the evidence of immunostimulatory effects of CP as well as its potent vaccine adjuvant candidate.

Chrysin is a major flavonoid of propolis that possesses physiological activities. We previously found a hydroxymethoxyl analogue on C4 of chrysin (CM) from gamma-irradiated chrysin. In this study, to examine whether CM has better potential as an anti-inflammatory candidate than chrysin, water solubility and anti-inflammatory activity of CM were investigated. CM showed the enhanced water solubility and lower cytotoxicity in bone marrow-derived dendritic cells (BMDCs) compared with original chrysin. CM exhibited the great anti-inflammatory activities in LPS-treated BMDCs, as demonstrated by the decreased level of pro-inflammatory cytokines (TNF-α and IL-12p70), surface molecules (CD80, CD86, MHC-I, and MHC-II), antigen-presenting ability. Furthermore, CM led to tolerogenic phenotype of BMDCs in the presence of LPS by increasing expression of indoleamine 2,3-dioxygenase-1, which is due to JNK and p38 activation. Subsequently, CM-treated BMDCs inhibited the proliferation and activation of CD4+ and CD8+ T cells while increased CD4+CD25+Foxp3+ regulatory T cells. Collectively, these results indicated that CM can be an attractive candidate of anti-inflammatory drug.

진행성 비호지킨 림프종 환자에서 ICE 구제 요법에 의한 조혈모세포 가동화 후 자가 말초혈액 조혈모세포이식

연구배경: 비호지킨 림프종에서 자가 말초혈액 조혈모세포이식술이 폭넓게 이용됨으로 인해서, 높은 치료효과뿐만 아니라 조혈모세포의 가동화 효율이 높은 구제 요법이 요구되었다. 방법: 본 연구에서는 진행성 비호지킨 림프종에서 ICE 요법을 이용하여 조혈모세포를 가동화시킨 후 자가 말초혈액 조혈모세포이식이 시행하였던 환자를 후향적으로 분석하였다. 결과: 대상 환자의 중앙 연령은 38세(범위, 16~61)였으며, ICE 요법은 환자당 4주기(범위, 1~6주기)가 투여되었고, 투여 간격은 중앙값이 24일(범위, 16~36일)이었다. 고위험도 관해군을 제외한 13예의 환자 중 완전반응은 7예(53.8%), 부분반응은 4예(30.8%), 진행성질환은 2예(15.4%)를 보였다. 치료에 따른 3~4등급의 혈액학적 독성은 중성구감소증이 13예(81.3%), 혈소판감소증이 7예(42.8%)에서 관찰되었다. 조혈모세포 채집은 ICE 요법 후 중앙값이 12일(범위, 6~20일)에 시행되었고, 각 ICE 요법당 채집한 단핵구치는 중앙값이 5.75× 10^(8)/체중, CD34^(+) 세포는 중앙값이 1.25× 10^(6)/체중, CFU-GM치는 중앙값이 1.19× 10^(5)/체중이었다. 조혈모세포이식은 11예에서 시행되었고, 중앙 추적기간 401일에 평가한 2년 전체생존율은 70.1±14.7%, 1년 및 2년 무사건생존율은 각각 60.7±15.4%와 32.3±17.1%를 보였다. 결론: ICE 요법은 재발성/불응성 비호지킨 림프종 환자에서 높은 치료 반응률과 만족할 만한 조혈모세포 가동화를 보여 주었지만, 치료에 대한 순응도가 낮아서 투여 간격이 연장되는 문제점을 안고 있어서, 우리나라 환자의 실정에 적합한 구제요법에 대한 연구가 필요할 것으로 생각된다. Background: Due to the extensive application of high-dose chemotherapy with autologous peripheral blood stem cell transplantation (PBSCT), a salvage chemotherapeutic regimen with high response rate as well as effective capacity of PBSC mobilization is needed in non-Hodgkin's lymphoma (NHL). Methods: We analyzed the applicability of ICE (ifosphamide, carboplatin, and etoposide) regimen in NHL patients who underewent autologous PBSCT. Results: The median age was 38 years (range, 16~61 years), the patients received median 4 cycles (range, 1~6 cycles) of ICE regimen, and the median interval between each chemotherapeutic cycle was 24 days (range, 16~36 days). There were 7 (53.8%) complete responses, 4 (30.8%) partial responses, and 2 (15.4%) progressive diseases after ICE regimen. Toxicity included grade 3/4 neutropenia and throm bocytopenia in 13 (81.3%) and 7 (42.8%) patients, respectively. PBSC collection began on median day 12 (range, 6~20 days) after ICE therapy. The median number of mononuclear cells, CD34+ cells, and CFU-GM was 5.75× 10^(8)/kg, 1.25× 10^(6)/kg, and 1.19× 10^(5)/kg, respectively. With a median follow- up of 401 days, the patients who underwent autologous PBSCT had overall survival with 70.1±14.7% at 2 year and event free survival with 60.7±15.4% and 32.3±17.1% at 1 year and 2 years, respectively. Conclusion: ICE chemotherapy is an effective cytoreduction and mobilization regimen in patients with NHL, but profound myelosuppression with delayed recovery might pose difficulties in applying for Korean patients. Further evaluation for appropriate salvage regimens in Korean patients should be needed.
