Purpose: This study was a predicative survey to provide home care clients with indwelling urinary catheters for furnishing basic educational material to their families by analyzing the family members' knowledge, educational needs and educational experience about indwelling catheter management. Method : The subjects consisted of 108 family members who cared for home care clients with indwelling catheters. Data were collected by home care nurses in nine hospitals in Pusan, who directly interviewed with them through questionnaires from Sep. 6th to 30th in 2004. The questionnaires for data collection were developed through pre-survey and reference review. The collected data was analyzed by using frequency, percentile, mean, variation, t-test, ANOVA on SPSS 10.1 package. Results : There were characters of home care clients with indwelling catheters: women(67.6%) were more than men; the average age of them was $69.60{\pm}14.99$ years old; neurogenic and cerebrovascular diseases(80.0%) were the most common disease group; 81.5% of them were totally dependent on others in terms of level of activity. Home care clients' families had these characters: women(76.9%) were more than men; the average age was $54.5{\pm}13.70$ years old; 46.3% of them were parents or sons or daughters in terms of relation with patient; tl1e average care period was $39.8{pm}34.20$ months. Level of knowledge about indwelling catheter management of the family members were 69.8% and its mean were $20.24{\pm}4.53$. Educational needs were 90.9% and its mean were $14.55{\pm}3.56$. Educational experience were 53.3% and its mean were $8.53{\pm}4.30$. 'Complications in using an indwelling catheter', 'Symptoms to call for a home care nurse' and 'Method to attach an indwelling catheter' were high ranked in both educational needs and educational experience. 'Anatomy of urinary tract', 'Functions of urinary tract' and 'Catheter placement' were low ranked in both educational needs and educational experience Level of knowledge about indwelling catheter management of the families showed a significant difference according to their age(F=5.35, p=0.01). Educational needs showed a significant difference according to care period(F=3.06, p=0.04). Conclusion: the family members' level of knowledge and educational experience about indwelling catheter management and their educational were not sufficient while their educational needs were high. In other words although the family members were acknowledged education needs, but the care for the patients with indwelling catheter weren't performed well because of their lack of related knowledge. Therefore systematic educational programs about indwelling catheter management for home care clients and their families should be made on the base of this study.

Arteriosclerosis is the major cause of coronary artery and cerebrovascular disease, which are leading causes of death. Pro-inflammatory cytokines induce injury to vascular endothelial cells by increasing cell adhesion molecules, leading to vascular inflammation, a major risk factor for the development of arteriosclerosis. In the current study, we investigated the inhibitory effect of enzymatic hydrolysate from Japanese mud shrimp Upogebia major on the inflammation of tumor necrosis $factor-{\alpha}$ ($TNF-{\alpha}$)-stimulated human umbilical vein endothelial cells (HUVECs). We first evaluated the antioxidant and angiotensin I-converting enzyme (ACE) inhibitory activities of eight U. major enzymatic hydrolysates: alcalase, papain, ${\alpha}$-chymotrypsin (${\alpha}-Chy$), trypsin, pepsin, neutrase, protamex and flavourzyme. Of these, ${\alpha}-Chy$ exhibited potent antioxidant and ACE inhibitory activities. The ${\alpha}-Chy$ hydrolysate was fractionated by two ultrafiltration membranes of 3 and 10 kDa. The ${\alpha}-Chy$ hydrolysate of U. major and its molecular weight cut-off fractions resulted in a significant reduction in NO production and a decrease in cell adhesion molecules [vascular cell adhesion molecule-1 (VCAM-1), intercellular adhesion molecule-1 (ICAM-1) and endothelial-selectin (E-selectin)] and pro-inflammatory cytokines [interleukin-6 (IL-6), interleukin-8 (IL-8) and monocyte chemoattractant protein-1 (MCP-1)] in $TNF-{\alpha}$-stimulated HUVECs. These results suggest that enzymatic hydrolysate from U. major can be used in the control and prevention of vascular inflammation and arteriosclerosis.

In order to anticipate disease pattern and health problems of Koreans in the 1st part of 21st century (by the year 2020), transition of population characteristics, mortality and morbidity data during the last 30 years Koreans have experienced were reviewed. On the actual basis of epidemiologic transition process that has undergone during last 30 years since 1960 along with socioeconomic development and successful implementation of selective national health policies (family planning, medical insurance and etc.), following changes can be expected in the 21st century in Korea, under the assumption that the current rate of progress is maintained. The population of South Korea alone will be doubled the population of 1960 by the year 2013 : aged Population older than 65 years will be increased from 3.3% in 1960 to 11.4% in 2020 with increased average age of the population from 23.6 year in 1970 to 39.2 year in 2020; urban population from 28% in 1960 to 83% in 2005. GNP/capita has increased tremendously from U.S. $120 in 1970 to $6,749 in 1992, and the government estimated it would be 519,350 in 2010 and $29,460 in 2020. Growth and developmental indices of children, educational achievement and social status of women also showed a remarkable improvement and anticipated to make futher progress. Leading causes of mortality and morbidity have shown a striking change during the last 30 years, from infectious diseases to chronic degenerative diseases and man-made injuries. Occurrence of communicable diseases may become minimal although viral hepatitis, venereal diseases Including AIDS, and well adapted herpes virus infections will maintain their endemic level. Newly evolving infectious agents, however, should be carefully monitored because of rapidly changing environments and human behaviours. Tuberculosis may increase up to the epidemic level when AIDS prevails. Ischemic heart diseases may increase steadily with increasing occurrence of hypertension and diabetes mellitus whereas cerebrovascular diseases may be decreased slowly. Musculaskeletal diseases which contribute a lot to the disability of aged people may be a major health problems due to increased aged population. Mental diseases, particularly that caused by alcohol and drug abuse, and senile dementia may become a prominent health problem. On the other hand injuries caused by traffic and industrial accidents that have shown most striking increase till now may be decreased considerably by intensive intervention. The health policies in the 21st century will be oriented to the health promotion for good quality life rather than life-savings.

There are few topic about a pulmonary thromboembolism(PTE) especially in Korean medical research. This case report is dealt with a rare situation that a PTE and a lacunar infarction are complicated in one patient. They have a similarity in that both are caused by the thrombosis. The former is the thrombosis in lung and the latter is the cerebral infarcion within the territory of a single perforating artery Recently the attack rate of PTE somewhat grow because of the development of medicine such as the increasing use of indwelling catheters, trauma or surgery of pelvis and lower extrimity, major surgery especially in senior, the use of estrogen containing compounds, cerebrovascular disease, obesity, etc. A 70 year-old lady was stroked by the cerebral infarction and has been getting rehabilitating therapy. She had the sudden onset of dyspnea, chest pain and those symptoms looked like a myocardial infarction. But she was diagnosed as PTE by ventilation perfusion lung scan. We cured her with the integrated therapy of Korean and Western medicine.

In this study, we prepared cordycepin-enriched (CE)-WIB801C, a n-butanol extract of Cordyceps militaris-hypha, and investigated the effect of CE-WIB801C on collagen-induced human platelet aggregation. CE-WIB801C dose-dependently inhibited collagen-induced platelet aggregation, and its $IC_{50}$ value was $175{\mu}g/ml$. CE-WIB801C increased cAMP level more than cGMP level, but inhibited collagen-elevated $[CA^{2+}]_i$ mobilization and thromboxane $A_2$ ($TXA_2$) production. cAMP-dependent protein kinase (A-kinase) inhibitor Rp-8-Br-cAMPS increased the CE-WIB801C-downregulated $[CA^{2+}]_i$ level in a dose dependent manner, and strongly inhibited CE-WIB801C-induced inositol 1, 4, 5-trisphosphate receptor ($IP_3R$) phosphorylation. These results suggest that the inhibition of $[CA^{2+}]_i$ mobilization by CE-WIB801C is resulted from the cAMP/A-kinase-dependent phosphorylation of $IP_3R$. CE-WIB801C suppressed $TXA_2$ production, but did not inhibit the activities of cyclooxygenase-1 (COX-1) and $TXA_2$ synthase (TXAS). These results suggest that the inhibition of $TXA_2$ production by WIB801C is not resulted from the direct inhibition of COX-1 and TXAS. In this study, we demonstrate that CE-WIB801C with cAMP-dependent $CA^{2+}$-antagonistic antiplatelet effects may have preventive or therapeutic potential for platelet aggregation-mediated diseases, such as thrombosis, myocardial infarction, atherosclerosis, and ischemic cerebrovascular disease.

LDL-콜레스테롤(LDL-C)은 심뇌혈관질환의 주된 교정 가능한 위험인자로서, 정확한 측정값을 임상에 적용하는 것이 중요하다. 하지만 LDL-C의 측정은 실제 측정이 아닌 Friedewald 공식에 의한 계산방법이 널리 이용되고 있다. 본 연구의 목적은 LDL-C의 Friedewald-추정값과 실측값을 비교하고, 두 방법의 LDL-C 위험수준 분류 일치도를 평가하는 것이다. 표본은 국민건강영양조사 2개년(2009년과 2010년)의 공개된 자료에서 추출되었고, 혈액 검사에서 총 콜레스테롤, HDL-콜레스테롤, 직접 측정한 LDL-C, 그리고 중성지방 중 어느 한 결측치도 없는 4,319명을 연구대상으로 하였다. 중성지방 400 mg/dL 미만일 때, Friedewald-추정값과 실측값은 높은 상관관계를 보였고 (r = 0.958, p < 0.001), 위험수준 분류 일치 백분율은 82.7%이었다. 중성지방 수준이 높을수록, 일치 백분율은 낮았다. 중성지방 수준 150 mg/dL 미만, 150-200 mg/dL, 그리고 200-399 mg/dL일 때, 일치 백분율은 각각 85.4%, 78.2%, 그리고 71.4%이었다. Friedewald 공식은 중성지방 농도 150 mg/dL 미만에서는 LDL-C를 과대평가하는 반면, 중성지방 농도 150 mg/dL 이상에서는 과소평가하는 경향이 있었다. 이에 따라 LDL-C 위험수준 분류에 있어 그 범주가 과대평가된 사람은 382명 (9.1%)인 반면, 과소평가된 사람은 348명 (8.3%)이었다. 이러한 결과는 Friedewald-추정값의 LDL-C 과소평가뿐만 아니라, 과대평가도 심각한 문제일 수 있음을 제시한다.

Objective : Hyperlipidemia and hypertension are well recognized risk factors of cerebrovascular disease. So it's very important to evaluate blood pressure and s-cholesterol in adolescence. Material and Methods : April 1999, we were requested health examinaion for high school students of a boys high school and a girls high school in Jeonbuk, Korea. The subjects were 360 students, boys were 317 and girls were 343. They were checked their height, body weight, blood pressure, and s-cholesterol. Results and Conclusion : The mean of systolic blood pressure of study subjects was $111.89{\pm}12.43mmHg$. In boys, it was $116.25{\pm}11.78mmHg$, and in girls, it was $107.87{\pm}11.64mmHg$. The mean of diastolic blood pressure of study subjects was $68.45{\pm}9.40mmHg$. In boys, it was $66.92{\pm}10.00mmHg$, and in girls it was $69.85{\pm}9.40mmHg$. Hypertensives were 18(5.68%) in boys, 10(2.92%) in girls. The mean of s-cholesterol of study subjects was $174.95{\pm}32.28mg/dL$. In boys, it was $178.91{\pm}34.51mg/dL$, and in girls, it was $171.29{\pm}29.66mg/dL$. Hypercholesterolemias were 91(28.71%) in boys, 39(11.37%) in girls. The mean of BMI of study subjects was $21.12{\pm}3.27kg/m2$. In boys, it was $21.05{\pm}3.26kg/m2$, and in girls, it was $21.18{\pm}3.29kg/m2$. Obese boys were 18(5.68%), obese girls were 13(3.79%). The mean of diastolic blood pressure in obese boys was significantly higher than that of normal boys(p=0.001, Mann-Whitney test). The mean of s-cholesterol in obese boys($BMI{\ge}274$) was significantly higher than that of normal boys.(P=0.26, Mann-Whitney test).

경제성장과 함께 생활습관 변화로 인한 만성질환이 지속적으로 증가하고 있다. 그 중 심뇌혈관질환은 사망원인의 약 20%를 차지하는 우리나라의 주요 사망원인이다. 심장의 이상을 측정하는 검사는 심전도검사로, 심장의 리듬을 전기적으로 측정하여 평가하는 방법이다. 심전도 검사에서 가장 영향을 미치는 것은 전극의 부착 위치인데, 간호사를 대상으로 연구한 결과에 따르면 모두 정확하게 부착한 것은 2.6%로 나타났다. 따라서 본 연구는 이러한 문제를 해결하기 위해 프로젝션 기반의 증강현실 기술을 사용하여 환자 본인의 Chest X-ray 사진을 흉부에 중첩시켜 투영시킴으로써 정확한 전극 부착위치를 쉽게 알 수 있는 시스템을 개발하였다. 기존의 방법으로 측정한 결과와 개발한 시스템으로 측정한 결과를 비교하였더니 2.6cm의 오차를 보였다. 그에 따른 심전도 결과에서도 V1, V2, V3위치에서 눈에 띄는 파형의 차이가 있었다. 본 시스템으로 정확하게 측정된 심전도는 의료진들의 환자관리 및 임상적 의사결정에 크게 도움이 될 것이다.

The contribution of endogenous transport systems to the blood-brain barrier (BBB) transport of basic and acidic drugs was studied by using a carotid injection technique in rats and an isolated bovine cerebrovascular disease state were compared between the normotensive rats (WKY) and stroke-prone spontaneously hypertensive rats (SHRSP) which have been well established as an animal model with pathogenic similarities to humans. Basic drugs such as eperisone, thiamine and scopolamine inhibited, in a concentration dependent manner the in vivo uptake of $[{^3}H]choline$ through BBB, whereas amino acids and acidic drugs such as salicylic acid and valproic acid did not inhibit the uptake. The uptake of $[^3H]choline$ by B-CAP increased with time and showed a remarkable temperature dependency. The uptake of $[^3H]choline$ by B-CAP showed the very similar inhibitory effects as observed in the in vivo brain uptake, and was competitively inhibited by a basic drug, eperisone. The in vivo BBB uptakes of $[^3H]acetic$ acid and $[^{14}C]salicylic$ acid were dependent on pH of the injectate and the concentration of drugs. Several acidic drugs such such as salicylic acid, benzoic acid and valproic acid inhibited the in vivo uptake of $[^3H]acetic$ acid, whereas amino acid, choline and a basic drug such as eperisone did not inhibit the uptake. The uptake of acetic acid by B-CAP was competitively inhibited by salicylic acid. The permeability surface area product (PS) through BBB for $[^3H]choline$ in SHRSP was significantly lower than that in WKY. The concentration of choline in the brain dialysate in SHRSP was about half of that in WKY, while no significant difference was observed in the plasma concentration of choline between SHRSP and WKY. No significant difference was observed in the transport of monocarboxylic acids, glucose and neutral amino acid through BBB between SHRSP and WKY. From these results, it was concluded that BBB transport system of choline contributes to the transport of basic drugs through BBB, that acidic drugs can be transported via a moncarboxylic acid BBB transport system and that the specific dysfuntion of the BBB choline transport in SHRSP was ascribed to the reduction of the maximum velocity of choline concentration in the brain interstitial fluids.

뇌혈관 질환은 우리나라의 주요 10대 사망 원인 중 3대 사인에 해당하며, 이러한 질환은 동맥경화와 관련이 있으므로 동맥경화를 예측할 수 있는 인자의 진단 방향의 제시가 필요하다. 본 논문에서는 연령대별 상완-발목동맥 맥파전달속도와 뇌동맥 혈관 협착 및 혈압, 비만도, 복부비만과의 유의성을 평가하였으며, 뇌동맥 혈관 협착과 연령대별 유의성 평가는 50대의 연령대에서만 유의한 결과를 나타내었으며, 동맥경화의 위험인자인 혈압, 비만, 복부비만의 경우 전체 연령대에서 유의한 결과를 나타내었다. 그리고 상완-발목동맥 맥파전달속도가 상승하였을 경우, 뇌동맥 혈관 협착은 전체 1,376명중 788명으로 57.2%의 분포를 나타내었으며, 위험인자인 혈압의 경우, 전체 7,557명중 3,255명으로 43%, 비만도는 2,708로 35.8%, 복부비만은 2,941명으로 38.9%의 분포를 나타내었다. 이러한 결과를 통하여 상완-발목동맥 맥파전달속도 검사 시, 동맥경화가 의심된다면 우선적으로 뇌동맥 혈관 협착을 의심하고 뇌동맥 혈관 검사를 시행할 것을 권한다. 동맥경화의 위험인자인 혈압, 비만, 복부비만과의 유의성 평가를 통하여 향 후 유사 연구 시, 기초자료로 활용될 것이라고 사료된다.
