  • Der p 2, which is a major allergen of house dust mite, plays an important role in the pathogenesis of allergic disease. There is controversy regarding whether Der p 2 binds to Toll-like receptor 4 (TLR4), and its inflammatory effect has not yet been elucidated. In the current study, we examined the interaction of Der p 2 with TLR4 and the effect of Der p 2 on cytokine release in THP-1 cells and lymphocytes. Among house dust mite extracts, recombinant TLR4 protein interacted with Der p 2. The overall structure of Der p 2 is characteristic of the immunoglobulin superfamily and contains ten ${\beta}-strands$, forming a ${\beta}-cup$ fold with two anti-parallel ${\beta}-sheets$, and a short 310 helix. The two sheets can be separated, further allowing the formation of a large internal pocket, which is narrow and suitable for binding large flat molecules such as lipid-like molecules. Der p 2 caused increased secretion of IL-6, IL-8, and MCP-1, which are neutrophil survival factors, in human monocytic THP-1 cells in a time-dependent manner. Der p 2 also induces the release of cytokines in normal and allergic lymphocytes. Supernatant after treatment with Der p 2 inhibited neutrophil apoptosis. In coculture of lymphocytes with neutrophils, Der p 2 inhibited spontaneous apoptosis of allergic neutrophils. In summary, Der p 2 binds to TLR4 and induces an inflammatory response such as cytokine secretion in immune cells. These findings may enable elucidation of allergy pathogenesis by specific allergen of house dust mite.

  • Purpose: This study was conducted to evaluate the effects of aerobic dance on physical functionnings of women with mastectomy. The study was single group pre- & post-test time series design. The aerobic dance program was performed three times a week for eight weeks, 45${\sim}$60 minutes per session. Method: The research variables used in the study were the period(seconds) of exercise that was taken for target heart rate, activity systolic pressure, range of motion of shoulder joint in affected side, and flexibility for physical functionnings. The data were analyzed with repeated measure ANOVA and Bonferroni multiple comparisons. Results: Over the period of aerobic dance, the degree of all the research variables were changed significantly, and also differed significantly every 2 to 4 weeks. The period(seconds) of exercise that was taken for target heart rate (p <.000), systolic pressure in exercise(p =.019), range of motions of shoulder joint on the affected side(flexion, abduction, over-adduction, over-extension, external & internal rotation), and flexibility(sit & reach, back & reach) (p= .003; p=.001; p(.001; p<.001; p= .014; p<.001; p=.036; p<.001) were differed significantly respectively. Conclusion: The results suggest that the aerobic dance program for women with mastectomy can improve and recover cardiopulmonary endurance and ROM of shoulder joint and that the period of exercise had to be performed over six to eight weeks and three times a week at least.

  • It has been postulated that oxidative stress may be increased and antioxidant defenses reduced in diabetes patients. Twenty-four patients with type 1 diabetes melitus (DM) (12.8$\pm$1.7 years) and 24 nondiabetics (12.5$\pm$2.1 years) were included in this study. Serum total cholesterol and LDL -cholesterol levels were significantly higher in diabetic than in nondiabetic control subjects, but serum levels of triglyceride , retinol , tocopherol, and $\beta$-carotene were significantly lower. Both $\beta$carotene and tocopherol levels inversely correlated with HbAlc, suggesting perhaps that low serum antioxidant level enhance theglycosylation of hemoglobin. Subjects with type 1 DM had lipid peroxide levels similar to those of nondiabetics control subjects, suggesting that per-oxdation of circulating lipid is not increased in uncomplicated diabeteics. The correlation between antioxidants and serum lipids were as follows ; retinol and LDL (r--0.36, p=0.019) ; retinol and total cholesterol(r=-0.35, p=0.020), tocopherol and LDL(r=-0.47, p=0.002) ; tocopherol and cholesterol (r=-0.49, p=0.001) ; $\beta$-carotene and LDL (r=-0.51, p=0.001). Overall , the results of this study were that serum lipid peroxide in patients with type 1 DM was similar to those of control subjects and antioxidants such as retinol, tocopherol and $\beta$-carotene were lower than those of nondiabetic cotnrol subjects, and negatively correlated with serum total cholesterol and LDL-cholesterol.

  • Diseases caused by indurate tissues of the internal organs are liver cirrhosis and abdominal sclerosis. The cause of chronic gastro-intestinal disease is a digestive system disorder and a defecation disorder. They impede peristaltic movement and digestive system with the symptom that indurate tissues. The purpose of the present study was to determine the disease grade quantitatively by measuring an indurated standard of tissues and organs. For the measurement of elasticity, we designed the system that measure the displacement of the substance and approved pressure using ultrasound transducer. For verification of developed system, we compared elasticity as results of experiment between the developed system and public elasticity measurement machine at individual plastic phantoms made by plastic hardener and softener. Elasticity of the plastic phantoms is averagely 0.007MPa lower measured by developed system than Micro-indenter, and less than 10% errors. Comparing with economical value and accuracy between developed system and Micro-indenter, the system is significant of measurement for tissue elasticity. Thus, it is possible to measure a elasticity at human tissue and organ. A chronic gastro-disease as well as grade could be decided objective validity using this system.

  • Anisakis spp. (Nematoda: Anisakidae) parasitize a wide range of marine animals, mammals serving as the definitive host and different fish species as intermediate or paratenic hosts. In this study, 18 fish species were investigated for Anisakis infection. Katsuwonus pelamis, Euthynnus affinis, Caranx sp., and Auxis thazard were infected with high prevalence of Anisakis type I, while Cephalopholis cyanostigma and Rastrelliger kanagurta revealed low prevalence. The mean intensity of Anisakis larvae in K. pelamis and A. thazard was 49.7 and 5.6, respectively. A total of 73 Anisakis type I larvae collected from K. pelamis and A. thazard were all identified as Anisakis typica by PCR-RFLP analysis. Five specimens of Anisakis from K. pelamis and 15 specimens from A. thazard were sequenced using ITS1-5.8S-ITS2 region and 6 specimens from A. thazard and 4 specimens from K. pelamis were sequenced in mtDNA cox2 region. Alignments of the samples in the ITS region showed 2 patterns of nucleotides. The first pattern (genotype) of Anisakis from A. thazard had 100% similarity with adult A. typica from dolphins from USA, whereas the second genotype from A. thazard and K. pelamis had 4 base pairs different in ITS1 region with adult A. typica from USA. In the mtDNA cox2 regions, Anisakis type I specimens from A. thazard and K. pelamis showed similarity range from 94% to 99% with A. typica AB517571/DQ116427. The difference of 4 bp nucleotides in ITS1 regions and divergence into 2 subgroups in mtDNA cox2 indicating the existence of A. typica sibling species in the Makassar Strait.

  • 신장은 간장과 가장 유기적인 관계가 깊은 장기로 혈액 중에서 체내 신진대사 결과 생긴 노폐물을 걸러내 오줌을 만들어 체외로 배출하는 기능을 한다. 그러나 신장은 문제가 발생할 경우 인체가 느끼는 자각증상이 크지 않기 때문에 장기 파손이 상당 부분 진행되어야 그 증상을 알게 된다. 따라서 사회적으로 신장 질환 진단에 대한 중요성이 증대되고 있다. 이를 위해 본 논문에서는 한방의 4대 진단법 중에서 망진과 청진 분야를 이용하여 신장질환에 대한 진단 방법을 제안하고자 한다. 본 논문에서 개발할 시스템은 크게 두 가지로 나누어진다. 하나는 입력 영상에 대한 보정을 통해 정확한 색상 값을 추출하고 최적화된 결과 영상을 통해 신장과 관련된 얼굴에서의 지각 부분의 색을 분석하고 그 값을 이용하여 신장 질환 진단을 하고자 한다. 또 하나는 신장과 음성 신호와의 관계론 비교, 분석하여 이를 입증하는 시스템을 설계하고자 한다. 끝으로 실험을 통해 제안한 방법의 유용성을 입증하고자 한다.

  • 호주의 많은 소동물 임상수의사들이 최근에 관심을 갖고 있는 부분은 개의 아토피(Canine Atopy)에서의 알러지-특이성(Allergen-specific)IgE에 쓰이는 혈청 ELISA (Enzyme-Linked Immuno-Sorbent Assay, 효소결합면역흡착검사)테스트의 활용 가능성에 관한 것이다. 희망사항은 개 아토피의 진단과 치료에 있어서 도움이 되도록 접근할 수 있는 시험(Accessible test)일 것이다. 아토피(Atopy)는 진단과 치료를 실패시키는 질병이며, 새로운 ELISA라도 이 문제를 쉽게 해결하여 주지 못한다. 개의 아토피에서 알려진(Allergens)들을 분석하는 데 쓰이는 혈청 ELISA처럼 아주 정확하게 특성화되어져야 한다. 해당 개는 아토피성(Atopic)으로서 진단되어져야만 되고 그 다음에 치료에 지침이 되도록 개별 알러진 동정(Individual allergen identification)용 ELISA로 개의 혈액을 스크린하는데 적합하여야 한다. ELISA와 피내접종시험(Internal testing)방법은 상관도가 낮고 그렇기 때문에 어떤 시험이 더 신뢰할 수 있는 것일까? 이러한 사실은 논쟁의 여지가 있으며 이상의 2가지 시험들이 옳다면 각각의 상응하는 각각 다른 아형(Subtypes)의 아토피라고 볼 수있다. 아마도 알러진들은 경피적으로 흡수되어 아토피성피부염으로 되어진다. 그것은 인체에서 건초열(Hay fever)이나 천식(Asthma)과 같이 흡입에 의해 일으키는 유사한 증후군동종 (Syndrome akin)과 같은 접근의 초기양식(Primary mode of access)으로부터 생기는 다른 유사한 질병과정이 되어질 수도 있다. 이러한 2가지 증후군은 함께 병발하는 경우가 있다. 의학에서는 피부 반점시험방법의 예비조사연구(Preliminary research with skin patch testing in medicine)는 아토피성 피부염을 야기하는 알러진들의 경피흡수경로의 개념을 지지해준다. 흡인 알러진들을 사용한 개들에서의 도전 시험(Challenge tests)들은 거의 대부분이 비-피부학적 임상증상들을 발현하였다. 모든 증거가 분명히 나타나도록 미래의 조사연구를 인도해 주는 게 필요하며 개 아토피의 정의와 진단을 둘러싼 수수께끼를 해결하는데 도움이 될 것이다.

  • Tazarotene-induced gene 1 (TIG1) is a retinoic acid-inducible protein that is considered a putative tumor suppressor. The expression of TIG1 is decreased in malignant prostate carcinoma or poorly differentiated colorectal adenocarcinoma, but TIG1 is present in benign or well-differentiated tumors. Ectopic TIG1 expression led to suppression of growth in cancer cells. However, the function of TIG1 in cell differentiation is still unknown. Using a yeast two-hybrid system, we found that transmembrane protein 192 (TMEM192) interacted with TIG1. We also found that both TIG1A and TIG1B isoforms interacted and co-localized with TMEM192 in HtTA cervical cancer cells. The expression of TIG1 induced the expression of autophagy-related proteins, including Beclin-1 and LC-3B. The silencing of TMEM192 reduced the TIG1-mediated upregulation of autophagic activity. Furthermore, silencing of either TIG1 or TMEM192 led to alleviation of the upregulation of autophagy induced by all-trans retinoic acid. Our results demonstrate that the expression of TIG1 leads to cell autophagy through TMEM192. Our study also suggests that TIG1 and TMEM192 play an important role in the all-trans retinoic acid-mediated upregulation of autophagic activity.
