  • Purpose : An understanding of the immunological process is required if primary prevention of atopic diseases is to be developed in early childhood. But, it is too hard to distinguish atopy from nonatopy under the age of two clinically, because the expression of phenotype and cytokines is vague in early childhood. We evaluated DNA methylation changes at Th2 interleukin-4 gene in peripheral blood from atopic children. Methods : We selected 15 allergic children(mild : eight, moderate to severe : seven) and seven normal controls by using family allergy scores and clinical histories. We measured Total IgE and Der f II specific IgE levels and cultured peripheral blood mononuclear cells with Der f II stimulation and extracted DNA from Der f II specific T cells. We examined the change of CpG methylation in DNA from atopic and nonatopic children. Results : In T cells from normal children, IL-4 DNA were predominantly methylated; otherwise, CpG demethylation occurred in Der f II specific T cells from allergic children. Conclusion : IL-4 DNA methylation changes occurred in T genes from allergic children and DNA methylation assay in early childhood.

  • Fucoidan has been shown to enhance immune function. The objective of this study was to examine the in vitro effect of fucoidan on the chamotactic activity of canine peripheral blood polymorphonuclear cells (PMNs). The chemotactic activity of PMNs was evaluated by method of a modified Boyden chamber assay. The amount of interleukin (IL)-8 in the culture supernatants from peripheral blood mononuclear cells (PBMCs) treated with fucoidan was determined by means of ELISA. Fucoidan itself could not have chemoattract effects for PMNs. However, the chemotaxis of PMNs was remarkably enhanced by culture supernatant from PBMCs treated with fucoidan. Similarly, it was also increased by recombinant canine (rc) IL-8. These chemotactic activities of PMNs were inhibited by addition of anti-rcIL-8 polyclonal antibody (pAb). The amount of IL-8 in the culture supernatant from PBMCs was shown to increase upon treatment of fucoidan as compared with that of untreated PBMCs culture supernatant. These results suggest that fucoidan upregulates the chemotaxis of PMNs, which is mainly mediated by IL-8 released from fucoidanstimulated PBMCs.

  • The objective of this study was to examine the effect of fucoidan on the phagocytic capapcity and oxidative burst activity (OBA) of canine peripheral blood polymorphonuclear cells (PMNs). The phagocytic capacity and OBA of PMNs were evaluated simultaneously by using a flow cytometer. Fucoidan itself did not cause any direct effect on the phagocytic capacity and OBA of PMNs. However, the phagocytic capacity and OBA of PMNs were enhanced by the culture supernatant from PBMCs treated with fucoidan. The phagocytic capacity and OBA of PMNs were also increased by treatment with recombinant canine (rc) tumor necrosis factor (TNF)-${\alpha}$. The ability of the culture supernatant from fucoidan-treated PBMCs to stimulate the phagocytic capacity and OBA of PMNs was inhibited by addition of anti-rc TNF-${\alpha}$ polyclonal antibody (PAb) prior to the culture. The amount of TNF-${\alpha}$ in the culture supematant from PBMCs was shown to increase upon treatment of fucoidan as compared with that of vehicle-treated PBMCs culture supematant. The level of TNF-${\alpha}$ mRNA expression in PBMCs was also up-regulated by the fucoidan treatment. These results suggest that fucoidan has an immunoenhancing effect on the phagocytic capacity and OBA of canine PMNs, which is mainly mediated by TNF-${\alpha}$ released from fucoidan-stimulated PBMCs.

  • 당뇨병성 신경병증은 망막증, 신증과 더불어 3대 당뇨병 합병증에 속한다. 당뇨병환자의 약 70%에서 발병한다고 하니 당뇨인이라면 누구나 거쳐 가는 증상이라 볼 수 있다. 처음에 손발의 감각이 무뎌지거나 저린감을 호소한다. 그러나 이 증상이 당뇨병 합병증인지 모르고 혈액순환 장애라 생각해 그냥 넘어가는 환자가 많다. 그뿐 아니라 말초신경병증은 한번 발생하면 치료가 쉽지 않고 효과를 나타내는데 상당한 시간을 요구하기 때문에 미리 예방하는 것이 중요하다.

  • 차세대염기서열분석법(NGS, Next Generation Sequencing) 기술은 하나의 유전체를 무수히 많은 조각으로 분해하여 각 조각을 동시에 읽어낸 뒤, 전산기술을 이용하여 조합함으로써 방대한 유전체 정보를 빠르게 해독하는 방법이다. 한편, 액체 생검(LB, liquid biopsy)이란 암세포가 깨지면서 생기는 미량의 DNA 조각을 말초혈액 속에서 찾아내 암을 진단하는 기술로 조직 생검(tissue biopsy)에 비해 비침습적이다. 본 논문은 NGS와 LB 기술을 접목했을 때 확진이 가능하고 예후 및 치료경과의 예측이 가능함을 제언하였다.

  • 추운 날씨가 지속되면 손발 저림 증상을 호소하는 환자들이 늘어난다. 오른손이 저리고 감각이 무뎌지는 듯 느껴지고 심지어는 물건을 집을 때 통증이 생기기까지 한다. 자주 손을 주물러 주고 마사지하는 것도 중요하지만 정확한 원인과 증상을 파악하고 제대로 된 치료를 받으려는 노력이 필요하다.

  • The current population of elderly is increasing and the with an extended average lifespan, the frequency of cancerous occurrences have also increased, with these increases and the increase in radiotherapy for cancer patients, recognitions of harm and importance have become known. This article was known tumor treatment of patients with hematopoietic disorder by doing a comparative study on the changes in blood cells caused by the acute effects of trace dose to high dose of radiation exposed to mice. According to the sensitizer injection may give rise to harm to the components of peripheral blood. This material needs to be considered when for treating tumor patients and the risks of hematopoietic harm and believe that radiation therapy will be reasonable.

  • The present study evaluated that responses of peripheral and bone marrow depends on the frequency of recombinant human granulocyte colony-stimulating factor (rhG-CSF) administration in dogs. The rhG-CSF has been revealed that have a beneficial effect for dogs with myelosuppression secondary to chemotherapy or radiation but there were no studies about the frequency of administration in dogs. In this research, rhG-CSF was administrated $5{\mu}g/kg$ subcutaneously for each two-dogs group as follows: (1) every day for trial, (2) every other day for trial, (3) every third day for trial. The peripheral blood analysis including direct microscopic differential counts of one hundred cells was performed every day. Bone marrow aspiration was performed before administration of rh G-CSF, on the day of 0, 3, 9 and when the WBC counts were decreased within the normal range (day 12 or 13). Rh G-CSF was well-tolerated and showed no side effects in all dogs. According to the present study, $5{\mu}g/kg$ administration of rhG-CSF have cell-specific, frequency-related effect on bone marrow and peripheral blood. Furthermore, the effects of rhG-CSF administration on bone marrow sustained during the study and prolonged at least 3 days after discontinuing of rhG-CSF treatment.

  • To examine the effectiveness of $\beta$-glucan in non-specific defence mecanisms of Korean catfish(Silurus asotus), the activities of peripheral neutrophils and serum lysozyme were evaluated after once or twice $\beta$-glucan injections. The number of peripheral neutrophils increased after the injection. The increased number in neutrophils in twice $\beta$-glucan injections maintained longer than in single glucan injecton. But the neutrophils did not showed any remarkable changes in PAS-positive reaction. Peripheral neutrophils from fish injected glucan had enhanced phagocytic activities but there was no significant difference in phagocytic index for the glucan and control groups. An elevation of lysozome activity was also observed in the fish received twice glucan but neither single glucan or physiological saline injection could not evoked an increase of lysozyme activity. These results suggest that $\beta$-glucan can enhance the resistance of Korean catfish against to bacteria infection through the activation of peripheral neutrophils and lysozyme.
