Essential thrombocythemia (ET), a subcategory of chronic myeloproliferative disorder, is characterized by absolute thrombocytosis due to excessive clonal proliferation of platelets, hyperaggregability of platelets, and increased incidence of thrombosis and hemorrhage. We consider a diagnosis of ET when an unexplained and persistent thrombocytosis is observed. It is difficult to consider ET first when we meet a patient with esophageal varix bleeding or unusual multiple thromboses like mesenteric vein, splenic vein, and portal vein. This article reports a patient who presented initially with esophageal varix bleeding and unusual multiple thromboses, thereafter, she was diagnosed with ET after testing positive for the Janus Tyrosine Kinase 2 (JAK2) V617F mutation. In conclusion, in patients with varix bleeding and unusual multiple thromboses, myeloproliferative disorders like essential thrombocythemia should be considered as a potential cause and testing for the JAK2 mutation is warranted.

목적 : 본 연구는 인간피부각질형성세포(HaCaT keratinocytes) 모델을 TNF-α와 IFN-γ로 자극하여 내복자(萊菔子)의 피부염증 감소 및 만성 염증성 질환에 미치는 영향을 알아보고자 하였다. 방법 : 내복자(萊菔子) 에탄올 추출물(RSE)이 세포생존율에 미치는 영향을 확인하기 위하여 MTT assay를 시행하였다. 또한 RSE가 TNF-α와 IFN-γ로 자극한 HaCaT 세포에서 p-IκBα, p-ERK, p-JAK2, p-STAT1, p-STAT6의 발현과 periostin, TSLP 단백질 발현에 미치는 영향을 확인하였다. 결과 : RSE는 200㎍/㎖ 이하에서 세포 독성을 보이지 않았고, HaCaT keratinocytes에서 TNF-α와 IFN-γ자극에 의하여 증가된 IκBα, ERK의 인산화를 억제하였다. 또한 JAK2와 STAT1, STAT6의 인산화를 억제하였으며, periostin과 TSLP의 발현을 감소시켰다. 결론 : RSE는 HaCaT keratinocytes에서 pro-inflammatory cytokines 및 transcription factors의 발현을 감소시켜 피부염증 감소 효능을 보였고, 만성 염증성 질환에서 내복자(萊菔子)의 사용 가능성을 확인하였다.

Leukemia is a clonal disorder with blocked normal differentiation and cell death of hematopoietic progenitor cells. Traditional modalities with most used radiation and chemotherapy are nonspecific and toxic which cause adverse effects on normal cells. Differentiation inducing therapy forcing malignant cells to undergo terminal differentiation has been proven to be a promising strategy. However, there is still scarce of potent differentiation inducing agents. We show here that Angelica sinensis polysaccharide (ASP), a major active component in Dong quai (Chinese Angelica sinensis), has potential differentiation inducing activity in human chronic erythro-megakaryoblastic leukemia K562 cells. MTT assays and flow cytometric analysis demonstrated that ASP inhibited K562 cell proliferation and arrested the cell cycle at the G0/G1 phase. ASP also triggered K562 cells to undergo erythroid differentiaton as revealed by morphological changes, intensive benzidine staining and hemoglobin colorimetric reaction, as well as increased expression of glycophorin A (GPA) protein. ASP induced redistribution of STAT5 protein from the cytoplasm to the nucleus. Western blotting analysis further identified that ASP markedly sensitized K562 cells to exogenous erythropoietin (EPO) by activating EPO-induced JAK2/STAT5 tyrosine phosphorylation, thus augmenting the EPO-mediated JAK2/STAT5 signaling pathway. On the basis of these findings, we propose that ASP might be developed as a potential candidate for chronic myelogenous leukemia inducing differentiation treatment.

유기농 녹차의 등급별 총페놀 함량과 항산화능은 각 추출 용매에 따른 수율을 확인하였을 때 물 추출에 비하여 수용성 유기 용매의 추출 수율이 유의적으로 높았다. 유기용매를 이용한 추출 수율은 물을 이용할 때 보다 총페놀 함량은 1.5에서 3.2배, 항산화능은 1.8에서 3.8배 정도 높게 나타났다. HPLC 분석을 통하여 총페놀 함량과 항산화능의 상관관계를 비교 시 총페놀 함량이 증가함에 따라 항산화능이 1차 선형관계로 증가하는 경향을 보였다. HPLC분석을 통하여 유기농 녹차에 함유되어 있는 다양한 카테킨의 함량이 채엽시기에 따라 변화가 나타났다. 유기농 녹차의 카테킨 성분 중 가장 많이 존재하는 EGCG가 건조중량당 5.8-7.7%의 함량을 보였고, caffeine은 1.7-2.9%의 함량을 보였다. 유기농 녹차의 카테킨 함량은 일반적으로 채엽 시기가 늦어짐에 따라서 점차 감소하였다. 유기농 녹차의 등급에 따른 항산화능은 최상급인 우전에서 가장 높았으며 최하등급인 엽차에서 가장 낮게 나타났다. HPLC 분석에 의한 유기농 녹차의 등급에 따른 총 카테킨 함량(mg/g)은 우전(155.4), 세작(147.7), 중작(143.2), 엽차(135.1), 대작(130.5)의 순서로 감소하였다. 이를 통해 녹차의 채엽 시기가 유기농 녹차의 카테킨 성분 및 항산화능에도 영향을 미치는 것을 확인하였다. 전반적으로 상급의 유기농 녹차 일수록 총페놀 및 카테킨 함량이 많으며 또한 더 높은 항산화능을 가지는 것으로 나타났다.

현대 자본주의 신자유주의 시장경제하에서 우리의 교육은 다시 한 번 시장 경제의 논리로 고교 선택제가 생기고 자본주의 논리에 의해서 대학을 위한 교육으로 전락해 버렸다. 이러한 가운데 교권은 흔들리게 되었고, 학교의 교육방침은 그야말로 어디로 가야할지 모르는 상황에 놓이게 되었다. 그런데 중국 고대의 철학자인 노자의 "도덕경"에서의 무위(無爲)사상과 신약성서 "빌립보서" 2장 6절-11절에 나오는 예수의 케노스(${\kappa}{\varepsilon}vo{\varsigma}$)의 사상은 우리 현대인들에게 주는 의미가 크다고 하겠다. 무위(無爲)란 작위(作爲)나 혹은 인위(人爲)의 반대의 개념으로서 자연의 도(道)인 자연스러운(nature) 상태대로 행하는 것을 말한다. 이것은 작위로 가득 차 있는 위정자들의 정치와 인간 사회에서의 인위에서 돌이켜 자연의 순리를 역행하지 말라는 것이다. 또한 케노스의 의미는 미움과 시기로 가득 차 있는 인간 세상에서 자신을 내어놓은 예수의 죽음을 통하여 이제 인간의 사명을 깨닫고 그 사명을 위하여 사랑과 헌신을 하라는 귀한 성인의 교훈이며, 이러한 교훈은 우리 교육의 현실 속에서도 많은 의미를 주고 있다.

Purpose: To test the effects of health education on the blood pressure, knowledge, and self-care of visiting nursing clients. Methods: The study subjects were 96 participants who had been diagnosed with hypertension or had high risk factors for hypertension among those registered at a public health center in Seoul. The education program was individualized and delivered to enhance the management of hypertension including life-style modification, medication, and complication managements. Data were collected using questionnaires from May to December 2006 and analyzed using descriptive analysis, t-test, paired t-test, and ANOVA. Results: The blood pressure of the participants after the education was significantly decreased compared to before the education. Education also significantly affected the increases of knowledge of the disease and self-care capability. However, the blood pressure and self care were not significantly improved for the age group over 85 years. Conclusions: This study proves that the individualized health education for visiting nursing clients was effective in improving blood pressure, knowledge, and self-care of hypertension. However, it is necessary to develop strategies that are specifically targeted at particular age groups in order to improve the capability of self-care of hypertension.

Objectives/Methods : To analyze the effect of Injinchunggantang(IJCGT) to Interferon-${\alpha}/{\beta}$ signal transmission system in HepG2 cells, HepG2 Cell were treated with IJCGT. Also, revelation of MxA, 2'5'-OAS mRNA leaded by Interferon-${\alpha}/{\beta}$ and revelation and activation of Jak1, TYK1, and STAT 1, all main signal transmission factors, were analyzed. Results : The analysis resulted in the following 1. With interferon ${\alpha}/{\beta}$ there was no affect cell propagation of Hep G2 cells. With IJCGT alone, cell propagation of HepG2 was promoted, and cell propagation control function was recovered. 2. With interferon ${\alpha}/{\beta}$ cell death was unaffected. With IJCGT apoptosis of HepG2 cell was restrained, and the cell's reaction to interferon was unaffected. 3. With interferon ${\alpha}/{\beta}$ treatment mRNA revelation of MxA and 2'5'-OAS was induced. When HepG2 cells were injected with IJCGT without interferon ${\alpha}/{\beta}$ treatment, mRNA revelation of MxA and 2'5'-OAS increased in proportion to the treatment density. With pre-treatment of IJCGT, leaded with interferon ${\alpha}/{\beta}$, promoted revelation of MxA, 2'5' -OAS mRNA. 4. Though mRNA revelation of lakl, TYK1 and STAT1 was unaffected with IJCGT, activation of STAT1 was promoted with an increase of phosphorylation of STAT1 protein. With pre-treatment of IJCGT, Jak1, TYK2, STAT1 phosphorylation, leaded with interferon, strengthened. 5. TNF-a, IL-1b and LPS present, revelation of MxA and 2'5'-OAS mRNA leaded by interferon was restrained when HepG2 cells were treated with IJCGT, and the interferon signal transmission system restraint action leaded by inflammatory cytokines was moderated. Conclusion : These results support a role for IJGCT in promotion of anti-virus action through maintainance of the liver's sensibility toward interferon. A clinical study of an interferon treated patient treated also with IJGCT is needed to determine its efficacy.
