<P><B>Aims</B></P><P>DJ-1/park7, a multifunctional protein, may play essential roles in the vascular system. However, the function of DJ-1/park7 in vascular contractility has remained unclear. The present study was designed to investigate whether the DJ-1/park7 is involved in the regulation of vascular contractility and systolic blood pressure (SBP).</P><P><B>Methods and results</B></P><P>Norepinephrine (NE) elevated contraction in endothelium-intact vessels in a dose-dependent manner, to a greater extent in DJ-1/park7 knockout (DJ-1/park7<SUP>−/−</SUP>) mice than in wild-type (DJ-1/park7<SUP>+/+</SUP>) mice. Acetylcholine inhibited NE-evoked contraction in endothelium-intact vessels, and this was markedly impaired in DJ-1/park7<SUP>−/−</SUP> mice compared with DJ-1/park7<SUP>+/+</SUP>. Nitric oxide (NO) production (82.1 ± 2.8% of control) and endothelial NO synthase (eNOS) expression (61.7 ± 8.9%) were lower, but H<SUB>2</SUB>O<SUB>2</SUB> production (126.4 ± 8.6%) was higher, in endothelial cells from DJ-1/park7<SUP>−/−</SUP> mice than in those from DJ-1/park7<SUP>+/+</SUP> controls; these effects were reversed by DJ-1/park7-overexpressing endothelial cells from DJ-1/park7<SUP>−/−</SUP> mice. Histone deacetylase (HDAC)-1 recruitment and H3 histone acetylation at the eNOS promoter were elevated and diminished, respectively, in DJ-1/park7<SUP>−/−</SUP> mice compared with DJ-1/park7<SUP>+/+</SUP> controls. Moreover, SBP was significantly elevated in DJ-1/park7<SUP>−/−</SUP> mice compared with DJ-1/park7<SUP>+/+</SUP> controls, but this elevation was inhibited in mice treated with valproic acid, an inhibitor of Class I HDACs including HDAC-1.</P><P><B>Conclusion</B></P><P>These results demonstrate that DJ-1/park7 protein may be implicated in the regulation of vascular contractility and blood pressure, probably by the impairment of NO production through H<SUB>2</SUB>O<SUB>2</SUB>-mediated epigenetic inhibition of eNOS expression.</P>

鄭憲瑩,琴坰樹,朴炅 대한한의진단학회 1998 大韓韓醫診斷學會誌 Vol.2 No.2

'Joe'(調) implies the harmony or the regulation, and 'Kyung'(經) indicates a meridian on that is translating meridian blood and Meridian-Qi. The Meridian channel is opened to the Five viscera(五藏) and the Six bowels(六腑) internally and that is connected with three hundred and sixty five joints externally. The body never occurs disease until Qi-hyul(氣血) is harmonied and Yin-Yang(陰陽) is balanced. If the disease occurs by means of the internal cause-the eating and drinking, the living of dwelling space, the importance of the emotion etc, I or by means of the external cause- the wind and rain, and the cold and dampness, it has influence on the Qi-hyul(氣血) of the body. Therefore with disharmony of the body has Qi-hyul, each kind of the Hei-shil disease brake(&實病燮) occur. From this chapter, Joe kyung(調經) implies the regulation that each kind of Hei-shil disease brake with ocwrance of the disorder of the body Yin-Yang-Qi-hyul(陰陽氣血), the shortage(&) is supplied, and the surplus(R) is decreased. Summerizing the contents of the "Joe Kyung Ron(調經陰)" in reference to the contents of successive generation note, the contents were as follows; In chapter 1, it was made clear that the revelation of the body normal physiological function had an action that connected human being's inside with it's outside, and that play the part of a passage in Qi-hyul(氣血) risvolving. In chapter 2, it was made clear about the plentiful disease, and it's administration of the Shen-Qi-Hyul-Hyung-Zhi(神·氣·血·形·志) with kept in the five viscera. In chapter 3, it was made clear about the Hei-shil(虛實) of the cause of the disease(病機), Qi-Hyul(氣血) union malim(雅氣), that by Qi-Hyul(氣血) itself union how Hei syndrome(虛證) and Shil syndrome(#%) are? In chapter 4, it was made clear that cause of a disease about Hei-Shil(虛實) has an attack of disease by pung(風)·woo(雨)·han(寒)·seo(署), and by the eating and drinking, the living of dwelling space and it explained the cause of a disease. In chapter 5, it explained the cause of a disease about Yin-Yang-Han-Yul(陰陽寒熱). In chapter 6, it explained an acupuncture technique about Hei syndrome(虛證) and Shil syndrome(l實證). chapter 7, it explained the method of Joe Kyung(調經) through the region of the body. The above contents had significient influence on the assortment and demonstration of the method of the acupuncture and moxibustion and disease in the future.

국소 광적응 기능을 가지는 윤곽검출용 시각칩을 픽셀수 32x32의 방사형 구조로 CMOS 공정기술을 이용하여 설계 및 제조하였다. 생체의 망막은 넓은 범위의 입력 광강도에 대해서 물체의 윤곽을 검출할 수 있다. 본 연구에서는 시세포, 수평세포, 쌍극세포로 이루어진 망막의 윤곽검출 기능을 모델링하여 윤곽검출용 인공시각칩을 설계하였다. 국소 광적응을 위해, 입력 광강도에 따라 수용야의 크기를 국소적으로 바뀌게 하였다. 아울러 단위셀을 방사형으로 배치함으로써 영상데이터의 양을 감소시킴과 동시에 칩의 중심부분으로 갈수록 해상도가 높아지도록 설계하였다. 설계된 칩은 0.6 ㎛ double-poly triple-metal 표준 CMOS 공정기술을 이용하여 제조되었으며. HSPICE 시뮬레이션으로 성능을 최적화 시켰다. A 32x32 pixels foveated (linear-polar) stucture retina chip with the function of local-light adaptation for edge detection has been designed and fabricated using CMOS technology. Human retina can detect a wide range of light intensity. In this study, we use the biologically-inspired visual signal processing mechanism that consists of photoreceptors, horizontal cells, and bipolar cells in order to implement the function of edge detection in the retina chip. For a local-light adaptive function, the size of receptive field is changed locally according to the input light intensity. The spatial distribution of sensing pixels in the foveated retina chip has the advantages of selective reduction of image data and good resolution in central part to carry out the elaborate image processing with still enough resolution in the outer parts. The designed chip has been fabricated using standard 0.6 ㎛ double-poly triple-metal CMOS technology and optimized using HSPICE simulator.

연구배경:당뇨병 환자에서 혈액응고 및 섬유소용해 체계의 이상경향이 있어 그 결과로 여러 혈관합병증의 발생위험이 높다는 사실은 널리 알려져 있다. 그 기전은 아직 확실히 밝혀지지 않았으나, 고혈당으로 인한 혈장 단백질들의 비효소성 당화작용이나 산화성 스트레스로 인한 유리 라티칼 작용으로 응고항진이나 섬유소용해 활성의 저하를 유발하는 것으로 생각되고 있다. 최근 응고 및 용해인자와 그 억제자의 복합체들의 증가가 이 상태를 비교적 예민하게 반영한다고 알려져 있다. 방법:본 연구에서는 당뇨병 환자 101명과 정상 대조군 20명에서 혈장내 thrombin­antithrombin complex(TAT)와 plasmin­α₂­plasmin inhibitor complex(PIC)를 측정하여 비교하고, 당뇨병 환자에서 미세혈관 합병증과 대혈관합병증의 유무에 따른 차이와, 이미 혈관 질환의 위험인자로 알려져 있는 인자들간의 상관성을 알아보고자 하였다. 결과:1. 환자의 분포를 살펴보면 혈관합병증이 있는 군은 85명, 혈관합병증이 없는 군은 16명이었고, 평균연령은 각각 57.9±14.1세, 49.9±16.6세로 혈관 합병증이 있는 군에서 더 나이가 많았고, 체질량지수는 23.2±3.4㎏/㎡, 24.1±3.4㎏/㎡로 두 군간 유의한 차이는 없었다. 또 두 군간의 혈압 및 HbA1c, 공복혈당 및 인슐린과 C­peptide, 총 콜레스테롤, 중성지방, HDL­콜레스테롤, Lp⒜는 유의한 차이가 없었고, 미세혈관합병증이 있는 군에서 당뇨병의 유병기간이 길었다. 2. TAT 및 PIC의 농도는 정상 대조군에서는 2.8±1.2 ng/mL, 240.4±69.7 ng/mL이었고, 당뇨병 환자군에서는 9.5±22.6 ng/mL, 472.2±258.7 ng/mL이었다. TAT와 PIC 모두 당뇨병 환자군에서 정상 대조군에 비해 유의하게 증가되어 있었고(p<0.001), TAT/PIC ratio는 두 군간 차이가 없었다. 3. 당뇨병 환자의 혈관합병증에 따른 TAT 및 PIC, fibrinogen 농도는 합병증이 없는 군은 각각 4.1±2.4ng/mL, 362.2±272.0ng/mL, 322.7±102.4mg/mL으로 PIC와 fibrinogen의 증가를 보였으나, 연령을 보정한 후에는 통계학적 유의성은 없었다. 또 대혈관 합병증군에서는 각각 6.0±4.9 ng/mL, 507.4±321.6 ng/mL, 427.1±194.7 mg/dL이었으며 미세·대혈관 합병증군에서는 10.4±6.4 ng/mL, 484.8±269.7 ng/mL, 388.4±132.4 mg/dL으로 TAT의 증가를 보였으나 역시 연령을 보정한 후에는 통계학적 유의성은 없었다. 4. 미세혈관합병증군에서 HbA1c(>8%)가 높은 군의 PIC 농도가 유의하게 높았고(p=0.049), 대혈관합병증군에서 HbA1c(>8%)가 높은 군의 총 콜레스테롤 농도가 유의하게 높았다(p=0.042). 5. 총 당뇨병 환자군에서 PIC는 fibrinogen과 HbA1c와 양의 상관관계를, BMI와 음의 상관관계를 보였으며(r=0.47, 0.31,-0.25), 혈관 합병증이 없는 당뇨병 환자군에서만 TAT는 HbA1c와 양의 상관관계를 보였다(r=0.67). 결론:이상의 결과에서 혈장 TAT 및 PIC 농도는 당뇨병 환자에서 정상 대조군에 비해 의미있게 증가되어 있었고, 당뇨병 환자군에서는 연령의 증가와 유병기간이 혈액응고항진 및 용해의 장애에 큰 역할을 함을 알 수 있었으며, 총 당뇨병 환자군에 PIC와 HbA1c와 양의 상관관계를, BMI와 음의 상관관계를 보였으며 혈관 합병증이 없는 당뇨병 환자군에서만 TAT는 HbA1c와 양의 상관관계를 보였다. 따라서 당뇨병 환자에서 혈액응고 및 용해의 장애가 동반되어 있다고 볼 수 있으며, 혈장 TAT 및 PIC는 혈관합병증으로의 진행을 예측하는 지표로서 유용하리라 생각된다. 또 혈당조절정도와 상관성이 있으므로 혈당조절후에 추적검사를 시행하여 합병증의 예방이 가능한지 추후 연구가 필요하리라 생각된다. Background : Abnormality of coagulation and fibrinolystic system is known as a predisposing factor of vascular complication in diabetes. Although the pathogenesis is not well known, non-enzymatic glycation reaction and the increase in production of free radicals due to an increased oxidative stress may be linked to the hypercoagulibility and hypofibrinolytic activity. As indices of abnormality in coagulation and firinolysis in peripheral blood, plasma thrombin-antithrombin Ⅲ complex (TAT) and plasmin-α_2-plasmin inhibitor complex (PIC) were measured. The purpose of this study was to clarify whether hypercoagulability exists in diabetic patients with or without vascular complication. Methods : In our study, we measured plasma thrombin-antithrombin Ⅲ compelx (TAT) and plasmin-α_2-plasmin inhibit or complex (PIC) in 101 diabetic subjects and 20 controls. Comparing TAT and PIC levels in diabetic microvascular complication group, diabetic macrovascular complication group and controls, we examined correlation between risk factors associated with diabetic vascular complication. Results : 1. The group with diabetic vascular complication was older than group without complication. There was no significant difference in BMI, blood pressure, HbA_ic, blood sugar level, insulin, C-peptide, serum creatinine, total cholesterol, triglyceride, HDL-cholesterol, Lp (a) between two groups. The group with diabetic microvascular complication had longer duration of diabetes. 2. Concentration of TAT and PIC were 2.8±1.2 ng/ mL, 240.4±69.7 ng/ mL in controls and 9.5±22.6 ng/ mL, 472.2±258.7 ng/ mL in diabetic patients, respectively. TAT and PIC were significantly higher in diabetic patients than in control (p<0.001). But TAT/PIC ratio was no significant difference between two groups. 3. In diabetic patients, concentration of TAT and PIC and fibrinogen were respectively 4.1±2.4 ng/ mL, 362.2±272.0 ng/ mL, 322.7±102.4 mg/ dL in group without vascular complication and 5.3±4.1 ng/ mL, 529.5±258.7 ng/ mL, 374.9±106.2 mg/ dL in group with microvascular complication, which group had increase in PIC and Fibrinogen but no significance after correction of age. Concentration of TAT and PIC and Fibrinogen were 60.±4.9 ng/ mL, 507.4±321.6 ng/ mL, 427.1±194.7 mg/ dL in macrovascular complication, and 10.4±6.7 mg/ mL, 484.8±269.7 ng/ mL, 388.4±132.4 mg/ dL in combined vascular complication which group showed increase of TAT but also had no significant increase after correction of age. 4. In diabetic microvascular complication patients, group of high HbA_1c (>8%) (p=0.049) had significant high PIC concentration. In diabetic macrovascular complication patients, group of high HbA_1c (>8%) (p=0.042) had significant high total cholesterol concentration. 5. In all diabetic patients, PIC was positively correlated with fibrinogen and HbA_1c and negatively correlated BMI (r=0.47, 0.31, -0.25). Only in daibetic patients without angiopathy, TAT was positively correlated with HbA_1c (r=0.67). Conclusion : In this study, plasma TAT and PIC concentration significantly increased in diabetic patients compared with controls, and PIC was increased in group with microvascular complication, TAT were increased in group with combined micro macrovascular complication. However, there was no significance relationship existed when correctinf for age. PIC was correlated with HbA_1c. TAT was correlated with HbA_1c only in the group without angiopathy. Abnormality of coagulation and fibrinolysis were combined in diabetes, plasma TAT and PIC can be used as an index of vascular complication. Also we found the correlation with the degree of the blood glucose control. Therefore we need follow up study for the possibility of prevention of vascular complication after controlling the blood glucose to age-matched patients (J Kor Diaabetes Asso 25:354~363, 2001).

파킨슨씨병 환자에 있어서 자가부신수질 이식술

Recent experimental studies and clinical cases have suggested that grafting tissue from the adrenal medulla into the brain may alleviate the symptoms of Parkinson's disease. Autologous adrenal medullary grafts into the striatum was performed stereotactically in two patients with Parkinson's disease. Both patients were bedridden preoperatively, but 4 months after the surgery both became ambulatory and one was even capable of returning to his job. Even though the number of cases was small⑵ and the follow-up period was short, this study shows that adrenal medullary transplantation into the striatum may have some beneficial effects in patient with Parkinson's disease. Further experimental and clinical trials are necessary to see whether this procedure will be a recommendable surgical treatment for patients suffering from Parkinson's disease.

蘇勇燮,鄭憲瑩,琴坰樹,朴炅 한국전통의학연구소 1998 한국전통의학지 Vol.8 No.2

The contents of Han Yul Byung(寒熱病) are explained on the basis of the so-called theory "Yin and Yang, the Five Evolutive Phases(음양오행)". The text of the Han Yul Byung(寒熱病) of the Young Chu(靈樞) was written in the Kap Ul Kyung(甲乙經) chapter 5, 7, 8, 10, 11 and 12. Also it was written in the Tae So(太素) volume 10 and 26. Also it was introduced in the Ryu Kyung(類經) volume 20, 21 and 22 by Jang Kae-Pin(張介賓) in the Myung(明) dynasty. Summarizing the contents of the Han Yul Byung in reference to the contents of successive generation note, the contents run as follows: Chapter 1 deals with the symptoms and treatment of diseases which accompany chills and fever(寒熱病). Chapter 2 deals with arthralgia with other joint systems(骨痺) and flaccid paralysis of Iimbs(體惰病). Chapter 3 deals with indications of five points around the Chen You Points(天牖穴). Chapter 4 deals with the treatment of toothache. Chapter 5 deals with the treatment of headache and eye pain. Chapter 6 deals with the acupuncture manipulation according to changes of season. Chapter 7 deals with the serious influence of carbuncle according to the region of body. Chapter 8 deals with the treatment of heat-syndrome. Chapter 9 deals with the side effect of acupuncture. It is too difficult to understand the Han Yul Byung(寒熱病), because it is written in old chinese. Consequence of above reason, the writer of this article has researched to find out the exact meaning of that.

素問·骨空論에 對한 硏究

曺基烈,鄭憲瑩,琴坰樹,朴炅 대한한의진단학회 1998 大韓韓醫診斷學會誌 Vol.2 No.2

The text of the Go1 Gong Ron (骨空論) of the So Moon (素問) was written in the Kap UI Kyung (甲乙經) volume 2 chapter 2 and volume 8 chapter 1. Also it was written in the Tae So (太素) volume 10, 11 and 26. In the Shin Kyo Jung (新校正), they say that it is wriien in the Jeon Won Ki Bon (全元起本) volume 2 and 6. But Wang (王永) interpreted it in volume 16. Also it was introduced in the Ryu Kyung (類經) volume 8, 9, 21 and 22 by Jang Kae Pin (張介賓) in the Myung (明) dynasty. In Go1 Gong (骨空), Gol(骨) means bone and Gong(空) means hole. So Go1 Gong(骨空) means the holes on bone of the human body. A large number of acupuncture points in 12 meridians are located on the holes of bone, and they are playing an important part in the treatment of diseases. In Go1 Gong Ron (骨空論), many points that is choosed when we treat various diseases by acupuncture are mentioned, locations that the holes of bone are distributed in are introduced. So it is called Go1 Gong Ron (骨空論) . This article of the research on the Go1 Gong Ron (骨空論) can be divided into 4 chapters. Summerking the contents of the Go1 Gong Ron (骨空論) in reference to the contents of successive generation note, the contents were as follows. Chapter 1 is about the way to use in treating various diseases what caused by Pung Sa (風??) and deals with the methods of locating acupoints based on a frame. Chapter 2 is written about lines that Conception Vessel (任??), Governer Vessel (????), and Throughfare Vessel (????) pass through, and pathological explanations on the diseases which are belong to those three meridians. The name of each part of the leg and the treatment corresponded to each phase of diseases of the leg are also mentioned in this chapter. Chapter 3 is concretely written about the name and position of the hole on bone of the human body. Chapter 4 deals with moxibustion therapy which we use to treat having an attack of indigestion, being bitten by dog, and feeling cold and heat in turn. Because the ancient men used acupuncture as main treatment of disease, they thought much of acupoint. A large number of acupoints are located on the holes of bone, and are playing an important part in the treatment of diseases. Therefore well understanding of Gol Gong Ron (骨空論) is very important. It is too difficult to understand the Gol Gong Ron (骨空論), because it is written in old Chinese. Consequence of above reason, the writer of this article has researched to find out the exact meaning of that.

素問·繆刺論에 對한 硏究(Ⅱ)

柳太植,鄭憲瑩,琴坰樹,朴炅 대한한의진단학회 1998 大韓韓醫診斷學會誌 Vol.2 No.2

The Scripture, the research on The MuJa Ron(○刺論) of the So Moon(素問), is described in the MuJa(○刺) of the Kap U1 Kyung(甲乙經). Also it is written in MuJa of Tae So(太素) volume 23,. And Wang(王○) interpreted it in volume 18 chapter 63. In ChimJaRyu(鍼刺類) of RyuKyung(類經) volume 20, it is introduced. And it is mentioned in the 2nd chapter of ShinKyoJung(新校正). In MuJa(○刺), Mu(#) means crossing left and right. Since this paper is describing the differences between MuJa(○刺) and KeoJa(巨刺), and it is also mentioning about carrying out the idea into practice, it is named MuJa(○刺). This paper, the theory of MuJa(○刺), can be divided into three properties in content. Chapter Ⅰ. deals with the common points and differences comparing with KeoJa(巨刺). Chapter Ⅱ. treats the idea that since RakMaek(絡脈) which is invaded by pathogenic factors are different, the states of the disorder are appeared differently so the place, method, atid number and order of acupuncture should be different. In chapter Ⅲ. it is said that in the state of disease of Kyung(經), KeoJa(巨刺) should be applied and in the state of the disease of Rak(絡), MuJa(○刺) should be used. treating oppositThe metabiosis of pathogenic factors flows from the skin and bodyhair to SonRak(孫絡), SonRak(孫絡) to RakMaek(絡脈), RakMaek(絡脈) to internal organs in general. In this situation KeoJa(巨刺) could be used in general. But if pathogenic factors flows irregularly, overflowing from one RakMaek(絡脈) to another place rather than internal organs, MuJa(○刺) could be applied. Therefore in the acupuncture treatment, the theory of MuJa(○刺) which implies side of the troubled places rather than the site itself is very important. But MuJa Ron(○刺論) is too difficult to interpret since is written in old Chinese, the writer of this paper has researched to prove the exact meaning of the MuJa(○刺).
