BACKGROUND/OBJECTIVES: Hypertension is the major risk factor for cardiovascular disease, a leading cause of deaths in Korea. The objective of this study was to evaluate the effect of a nutrition education in reducing sodium intake and increasing potassium intake in hypertensive adults. SUBJECTS/METHODS: Subjects who participated in this study were 88 adults (28 males and 60 females) who were pre-hypertension or untreated hypertensive patients aged ≥ 30 yrs in Gyeonggi Province, Korea. These subjects were divided into 2 groups: a lowsodium education (LS) group and a low-sodium high-potassium education (LSHP) group. Nutrition education of 3 sessions for 12 weeks was conducted. Blood pressure, blood and urine components, nutrient intake, and dietary behavior were compared between the two education groups. RESULT: Blood pressure was decreased in both groups after the nutrition education (P < 0.05). In the LSHP group, levels of blood glucose (P < 0.05), total cholesterol (P < 0.01), and lowdensity lipoprotein-cholesterol (P < 0.05) were decreased after the program completion. Sodium intake was decreased in both groups after the nutrition education (P < 0.05). However, Na/K ratio was only decreased in the LS group (P < 0.05). Intake frequency of fish & shellfish was only significantly reduced in the LS group (P < 0.05), while intake frequencies of cooked rice, noodles & dumplings, breads & snacks, stew, kimchi, and fish & shellfish were reduced in the LSHP group (P < 0.05). Total score of dietary behavior appeared to be effectively decreased in both groups after the education program (P < 0.001). CONCLUSIONS: This education for reducing sodium intake was effective in reducing blood pressure and sodium intake. The education for enhancing potassium intake resulted in positive changes in blood glucose and serum cholesterol levels.

This study was undertaken to define the effect of DaeSiHo-Tang extract on the hypertension in spontaneous hypertensive rat and norepinephrine-induced arterial contraction in rabbit. Systolic blood pressure and blood velocity were significantly attenuated by administration of DaeSiHo-Tang extract. but blood flow and renin-angiotensin-aldosterone system unaffected by DaeSiHo-Tang extract. The relaxation effect of DaeSiHo-Tang extract was dependent on the presence of endothelium, showing that DaeSiHo-Tang extract-induced relaxation was not observed in the strips without endothelium. The endothelium-dependent relaxation induced by DaeSiHo-Tang extract was decreased by the pretreatment of $N{\omega}$-nitro-L-arginine or methylene blue, but it was not observed in the strips pretreated with indomethacin or tetraethylammonium chloride. When $Ca^{2+}$ was applied, the strips which were contracted by norepinephrine in a $Ca^{2+}$-free solution, arterial contraction was increased. But pre-treatment of DaeSiHo-Tang extract inhibited contractile response to $Ca^{2+}$. These results indicate that antihypertensive effect of DaeSiHo-Tang extract is due to descend arterial resistance by the arterial relaxation through the formation of nitric oxide in the vascular endothelial cells.

8개월령 암컷 포메라니안 개가 심잡음과 심비대를 주호소로 내원하였다. 검사결과 좌-우단락 동맥관 개존증과 중등도의 심부전 (ISACHC II) 으로 진단되었다. 잔존 동맥관은 우측 대퇴동맥을 통한 $5mm{\times}3loops$ 코일 색전술을 통해 성공적으로 치료되었다. 2개월 후 환축은 현저한 저혈압과 심한 설사, 흉수가 차는 증상으로 다시 내원하였다. 검사 결과 심각한 폐성고혈압과 삼첨판 역류가 발견되었다. Sildenafil (3 mg/kg, PO, TID) 을 투여함으로써 임상증상은 조절되었으나, 코일빠짐과 보호자의 부적절한 투약으로 인해 환축은 폐사하였다. 부검 결과 폐성고혈압의 원인은 비정상적인 위치로 빠진 색전 코일에 의한 것으로 밝혀졌다. 토이 품종에서 PDA의 치료를 위해 색전 코일이 널리 사용되고 있지만, 장착된 코일이 빠질 위험을 줄이기 위해서는 PDA의 크기와 형태에 대한 한층 더 세심한 평가가 필요하다.

Objective: To quantitatively assess the pulmonary vasculature using non-contrast computed tomography (CT) in patients with chronic thromboembolic pulmonary hypertension (CTEPH) pre- and post-treatment and correlate CT-based parameters with right heart catheterization (RHC) hemodynamic and clinical parameters. Materials and Methods: A total of 30 patients with CTEPH (mean age, 57.9 years; 53% female) who received multimodal treatment, including riociguat for ≥ 16 weeks with or without balloon pulmonary angioplasty and underwent both non-contrast CT for pulmonary vasculature analysis and RHC pre- and post-treatment were included. The radiographic analysis included subpleural perfusion parameters, including blood volume in small vessels with a cross-sectional area ≤ 5 mm² (BV5) and total blood vessel volume (TBV) in the lungs. The RHC parameters included mean pulmonary artery pressure (mPAP), pulmonary vascular resistance (PVR), and cardiac index (CI). Clinical parameters included the World Health Organization (WHO) functional class and 6-minute walking distance (6MWD). Results: The number, area, and density of the subpleural small vessels increased after treatment by 35.7% (P < 0.001), 13.3% (P = 0.028), and 39.3% (P < 0.001), respectively. The blood volume shifted from larger to smaller vessels, as indicated by an 11.3% increase in the BV5/TBV ratio (P = 0.042). The BV5/TBV ratio was negatively correlated with PVR (r = -0.26; P = 0.035) and positively correlated with CI (r = 0.33; P = 0.009). The percent change across treatment in the BV5/TBV ratio correlated with the percent change in mPAP (r = -0.56; P = 0.001), PVR (r = -0.64; P < 0.001), and CI (r = 0.28; P = 0.049). Furthermore, the BV5/TBV ratio was inversely associated with the WHO functional classes I-IV (P = 0.004) and positively associated with 6MWD (P = 0.013). Conclusion: Non-contrast CT measures could quantitatively assess changes in the pulmonary vasculature in response to treatment and were correlated with hemodynamic and clinical parameters.

본 연구는 고혈압전단계 남자 대학생들이 단순 일회성 유산소 운동을 운동강도를 달리하여 혈압, 혈중지질, 섬유소용해 인자에 미치는 영향에 대하여 연구하였다. 총 6명이 최종 실험 참가자로 선정되어 일회성 달리기 운동을 저강도(50-60% 여유심박수(Heart rate reserve(HRR)), 중강도(60-70%HRR), 고강도(70-80%HRR)로 실시하였다. 혈압(수축기와 이완기), 혈중지질(총 콜레스테롤(total cholesterol(TC), 고밀도단백질 콜레스테롤(high-density lipoprotein cholesterol(HDL-C)), 섬유소 용해인자(tissue plasminogen activator(tPA) and plasminogen activator inhibitor-1(PAI-1))는 운동 전과 후 그리고 운동 후 60분 각각의 강도마다 측정되었다. 실험결과는 저강도 그룹의 수축기 혈압은 운동 후에 유의하게 상승하였다(p=0.013). 하지만 중강도와 고강도 그룹의 수축기 혈압은 유의미하지는 않았으나 효과크기로 분석시 운동 후 60분에 -1.33과 -1.23으로 큰 효과를 보이며 낮아졌다. HDL-C는 중강도(p=0.003)와 고강도 그룹(p=0.002)에서 운동 후 60분에 유의하게 증하였다. tPA는 중강(p=0.021)와 고강도 그룹이(p=0.042) 운동 후에 유의하게 증가하였다. 그리하여 일회성 중강도와 고강도 운동을 했을 때 운동 후 저혈압이 나타나고 HDL-C가 높아지고 또한 tPA 농도가 높아져서 고혈압 전 단계 젊은 남자들이 지속적인 중강도 이상의 운동을 하게 되면 고혈압과 심혈관질환을 예방하고 지연시킬 것이다.

Purpose: This study was conducted to examine and compare clinical manifestations and predicting factors for treatment-seeking delay among patients <65 and ${\geq}65\;yr$ with first-time acute coronary syndrome (ACS). Methods: A total of 288 patients who were diagnosed with ACS were individually interviewed at C university hospital in G-city from November 2007 to December 2008. Results: Median pre-hospital delays for younger and older patients were 5 and 12 hr, respectively. Younger patients were more likely to be current smokers, heavy drinkers, obese, stressed, and have an unhealthy diet and family history, and to complain of chest pain, left shoulder and arm pain, perspiration, and nausea. Older patients were more likely to have hypertension and diabetes, and to complain syncope and dyspnea. Logistic regression analyses showed that after adjustment for age, gender and education, progressive onset of symptom and no attribution to cardiac problem significantly predicted pre-hospital delay >3 hr in both younger and older patients. Low perceived health status was a significant independent predictor in older patients only. Conclusion: Health care providers should be concerned with different manifestations between younger and older adults, and educate people at risk for heart attack about symptoms and actions to get immediate help.

Zearalenone (ZEA) is a phenolic resorcylic acid lactone compound produced by several species of Fusarium. ZEA has toxic effects in the testes of domestic and laboratory animals. Korean red ginseng (KRG), the steamed root of Panax ginseng Meyer, has multiple pharmacological effects such as vasorelaxation, anti-thrombosis, anti-hypertension, etc. In this study, we investigated the effects of KRG extract on testicular toxicity induced by ZEA. Rats were treated with 300 mg/kg oral doses of KRG for 4 weeks every other day. The rats were then treated with a single dose of 5 mg/kg ZEA delivered intraperitoneally, whereas control rats received only doses of the vehicle. As a result, germ cell apoptosis induced by ZEA was decreased by KRG pre-treatment. In addition, Fas and Fas-L expression was reduced in rats that received KRG pre-treatment compared to ones treated with ZEA alone. In conclusion, impaired spermatogenesis resulting from ZEA treatment was prevented by KRG through Fas-Fas L modulating.

Purpose: This study was to estimate salt preference and sodium intake of pregnant women, and identify the relationship between salt preference and sodium intake. Methods: Research design was a cross sectional correlational survey with 197 pregnant women who visited outpatient clinics for antenatal care. The sodium intake levels were estimated by the amounts of sodium intake using the 24-hour recall method and sodium concentration in spot urine. The data were analyzed using descriptive statistics, t-test, ANOVA and Pearson's correlation. Results: Sodium intake using 24-hour recall method was $3,504{\pm}1,359mg$. Sodium intake levels had statistically significant differences depending on income. The average amount of sodium in spot urine was $2,882{\pm}878mg/day$. Sodium excretion levels had statistically significant differences depending on whether participants had preexisting hypertension in their family history and Body Mass Index (BMI) pre-conception. Salt preference was $62.61{\pm}20.96$ out of 180 points. Salt preference had significant differences depending on income, parity, gestational age, BMI pre-conception and showed negative correlation with sodium quantity in spot urine. Conclusion: Sodium intake in pregnant women recommended by World Health Organization recommended is 175%. Salt preference was not significantly different between sodium intake levels, however it was negatively correlated with sodium quantity in spot urine among pregnant women.

PURPOSE : Andrographis Herba is used as a traditional herbal medicine in the Asian countries for the treatment common cold, fever, diabetes, hypertension, hepatitis, skin infections, snake bite, and other diseases. In this study, we investigated the anti-inflammatory effect of MeOH extract of Andrographis Herba (AHME) on LPS-activated Raw 264.7 cells. METHODS : Cell viability was determined by MTT assay. Nitric oxide (NO) production was determined by Griess reagent. Pro-inflammatory cytokines were detected by enzyme-linked immunosorbent assay. Expression levels of pro-inflammatory proteins were determined by Western blot analysis. RESULTS : Production of NO in LPS activated Raw 264.7 cells, was significantly decreased by pre-treatment with 3-30 ㎍/mL of AHME. Production of pro-inflammatory mediators such as TNF-α and IL were significantly decreased by AHME 30 ㎍/mL pre-treatment. AHME significantly decreased p-IκB and NF-κB expression. CONCLUSION : The results of this study indicate that AHME could inhibit the acute inflammatory response, via modulation of NF-κB activation.
