Non processed onion (Allium cepa L.) powder or onion powder processed with β-cyclodextrin+1% calcium chloride+1% soluble starch solution was added to the diet of 16 week old Wistar and spontaneously hypertensive rats (SHR) for 5 weeks. 36 SHR and Wistar rats were randomly divided into 3 diet groups, each of six. They were named control, NPO (non processed onion), PO (processed onion). The rats of the control group were fed diet without onion powder. To NPO and PO groups were added 5% of non processed onion and processed onion, respectively. Body weight gain, food efficiency ratio (FER), blood pressure, angiotensin converting enzyme (ACE) activity and Na excretion of urine and feces were analyzed. The processed onion and non processed onion diet reduced body weight gain without affeting the total food intake in Wistar rats (p〈0.05). The body weight gain was lowest in Wistar rats fed with a diet with processed onion powder. The rats fed with diet containing PO or NPO had lower blood systolic blood pressure in SHR (p〈0.05). The effect of onion powder on decreasing the blood pressure was not significant in Wistar rats. The ACE activity in lung was lowered in the SHR fed with either PO or NPO (p〈0.05) compared to those fed with control diet. The urinary Na excretion was significantly lower in SHR than Wistar rats. The effects of PO and NPO on increasing the urinary and fecal excretion of Na were significant (p〈0.05). These results suggest that onion processed with β-cyclodextrin+1%+1% calcium chloride+1% soluble starch solution to reduce volatile flavor, browning and caking preserves an antihypertensive effect of non processed onion.

This Study aims at looking into the use of oriental medical services in treating hypertension. The first objective to be explored through this study is the morbidity caused by the disease, classifying them by age, gender, and occupation. The second is to determine the regular use of anti-hypertensive medicine and their efficacy in controlling blood-pressure. The third is to investigate the use-rate and satisfaction of oriental medical service. 838 households across the country, were asked to answer questionnaires for the period of time from Apr. to Jun. 2005. The conclusion from the survey can be summarized as following. The age of which the first medical diagnosis of hypertension were made showed lower in males, those with higher education and income. The study showed females were more active in blood-pressure control, with their frequent monitoring of blood-pressure for the past year. With age, people in under 50 age group proved to be less active. The management of high blood pressure was more effective in group with regular dosage compared to group with irregular use of anti-hypertensive medication, but their difference was minimal. Also, group with no medication showed signs of blood-pressure control. The use of oriental medical service for the past year, were more frequent in groups with lower education, either low or high income, old age, females and occupations in agriculture, forestry and fishing industry. Results were similar in both general population and high blood-pressure patient group. Females, people over 51 years old and with lower education showed more intentions in utilizing oriental medical services in the future. Results were similar in both general population and high blood-pressure patient group. It is necessary to offer a more accurate information on oriental medical treatments. Also, a systematic reform to reduce the patient's share of the treatment cost, as well as, heightening public awareness on the infirmity of present blood-pressure management system is crucial.

This study was conducted to examine the correlation among meals variety, obesity index, blood pressure, and lipid profiles of Korean adults. A total of 308 adults(men 124, women 184) measured the anthropometric characteristics, blood pressure, dietary intake using 24-hour recall method, and serum lipid profile. The average ages of the study subjects were 50.9 yrs in men and 51.4 yrs in women. The average height, weight and BMI were 166.3 cm, 68.4 kg, 24.7 kg/cm2 in men and 154.3 cm, 59.8 kg, 25.0 kg/cm2 in women, respectively. The numbers of food items in meal of men and women were 14.1, 15.9 for breakfast, 15.7, 15.9 for lunch, 14.7, 14.1 for dinner, respectively. The numbers of dish items in meal of men and women were 4.0, 4.3 for breakfast, 4.3, 4.3 for lunch, 4.2, 3.9 for dinner, respectively. The average blood pressure, total cholesterol, triglyceride, HDL-cholesterol, LDL-cholesterol and atherogenic index were 126.6/76.0 mmHg, 181.0 mg/dL, 157.7 mg/dL, 40.9 mg/dL, 108.6 mg/dL, 3.5 in men and 123.2/73.6 mmHg, 185.0 mg/dL, 137.3 mg/dL, 44.8 mg/dL, 112.7 mg/dL, 3.2 in women, respectively. The total cholesterol was negatively correlated to the number of food item for lunch(p〈0.05). Therefore, more systematic studies to investigate the meal variety roles of blood lipids in meals of adults were required.

As an attempt to develop new functional health beverage by using medicinal herb, green ginger(Zingiber officinale Roscoe), we investigated the effect of Zingiber officinale on blood pressure and regional cerebral blood flow (rCBF) of rats with Zingiber officinale extracts. Zingiber officinale extract increase rCBF significantly. The drink produced consisted of Zingiber officinale extract 1.825%, maltitol syrup 17.0%, citric aicd 0.06%, ascorbic acid 0.02%, stevioside 0.001%, ginger flavor 0.11% and water. Brix, pH and acidity of product were 13.7, 4.4 and 0.09, respectively. This drink had good score by the sensory evaluation. The above results showed that development of such functional beverage using Zingiber officinale can used as a functional material improving blood circulation in beverage industry.

The purpose of this study is to measure the changes of regional cerebral blood flow (rCBF) and blood pressure (BP) in rats, following the intravenous injection of Catalpa Ovata Water Extract (COWE). The measurement was continually monitored by laser-doppler flowmeter (Transonic Instrument, USA) and pressure tranducer(Grass, USA) in anesthetized adult Sprague-Dawley rats through the data acquisition system composed of MacLab and Macintosh computer. The result of this experiment was as following : COWE increased the changes of rCBF and BP significantly. After pretreatment with propranolol and indomethacin, the changes of rCBF were inhibited significantly, but not by L-NNA and methylene blue. Also, after pretreatment with propranolol, the changes of BP were inhibited significantly, but not by L-NNA, methylene blue and indomethacin. According to above result, it is considered that Catalpa Ovata increased the rCBF and BP, related to adrenergic β-receptor.

1. Background and Purpose For many years, Sibimikwanjungtang, Yangkyeoksanhwatang and Hyeongbangsabaeksan have been used as a therapeutic agent in constitutional disease. The effects of three prescriptions on the vascular system is not well-known. The purpose of this study is to determine the effects of these prescriptions on blood pressure(BP) and regional cerebral blood flow(rCBF). 2. Methods I injected a vein of rat with extracts of Sibimikwanjungtang, Yangkyeoksanhwatang and Hyeongbangsabaeksan with five kinds of dose and measured BP and rCBF. 3. Results After injected Sibimikwanjungtang, BP was not changed but rCBF was increased in a dose-dependent manner. After injected Yangkyeoksanhwatang, BP was elevated and rCBF was increased in a dose-dependent manner. After injected Hyeongbangsabaeksan, BP was not changed but rCBF was increased in a dose-dependent manner.

The aim of the experiments was to investigate the effect of Fructus Tribuli on the blood pressure, plasma renin activity, plasma levels of aldosterone and atrial natriuretic peptide (ANP) in spontaneously hypertensive rats (SHR). The results of this study were as follows: 1. Systolic blood pressure decreased significantly after the administration of Fructus Tribuli water extract 0.03 ㎖/200 g. 2. Plasma renin activity and plasma levels of aldosterone were not changed after the administration of Fructus Tribuli water extracts. 3. Plasma levels of atrial natriuretic peptide (ANP) decreased significantly after the administration of Fructus Tribuli water extracts.

The purpose of this study is to determine cardiovascular reponses to concentric, eccentric and isometric exercise applied to the knee extensor muscle group. Exercise types studied were concentric, eccentric and isometric. The subjects were sixty healthy male volunteers who had no hypertension or cardiac disease. Heart rate, systolic and diastolic blood pressure were recorded prior to starting exercise. The subjects also performed 10RM on right lower extremity. A N-K table was used for three exercises to right knee extensors. Each exercise was selected randomly and applied to each subject 10 times in a 10 second. After each exercise, heart rate, systolic and diastolic blood pressure were recorded immediately. Findings were as follows concectric contractions had a greater effect on the increase of systolic blood pressure and heart rate than eccentric or isometric contractions. Diastolic blood pressure is influenced only by isometric contractions. Eccentric contractions have less effect on the increase of systolic blood pressure and heart rate than concentric or isometric contractions. We hope that the results of this experiment can be adapted to exercise programs for patients with cardiac disease.

We compared effects of fruit, leaf, and stem extracts from black raspberry on improvement of cholesterol and blood pressure in HepG2 and HUVEC cells, respectively. Cholesterol secretion was inhibited by water extracts of unripe fruit and stem, but not leaf of black raspberry in HepG2 cells. Also, water extracts of unripe fruit, leaf, and stem reduced HMG-CoA reductase activity. Furthermore, nitric oxide production and expression of angiotensin-converting enzyme (ACE) protein were regulated by extracts of fruit, leaf, and stem of black raspberry in HUVEC cells. Overall, the rank order according to the improving level of cholesterol and hypertension is as follows: stem > fruit > leaf. In addition, various polyphenol compounds displayed inhibitory effects of HMG-CoA reductase activity and ACE expression. Thus, these data suggested that leaf and stem as wells as fruit of black raspberry can be used as useful food resources for reduction of cholesterol and blood pressure.

본 연구는 원예치료프로그램이 정신분열병 환자의 혈압, 맥박 및 정서안정에 미치는 영향에 대하여 알아보고자 실시하였다. 대구광역시 남구 대명동에 위치한 남구정신보건센터를 이용하고 있는 정신분열병 남녀 7명을 대상으로 2002년 7월 9일부터 2002년 10월 1일까지 3개월간 주1회 총 12회 원예치료프로그램을 실시하였다. 매 프로그램 실시 전․후에 혈압, 맥박을 측정한 결과 수축기혈압의 경우 원예치료 실시 전 91.5에서 실시 후 87.04로 낮아졌으며 0.10수준의 차이가 있었다. 확장기혈압의 경우 원예치료 실시 전 69.49에서 실시 후 65.27로 4.22로 낮아졌으며 0.05수준의 차이가 있었다. 맥박의 경우도 혈압과 마찬가지로 원예치료 실시 전 81.79에서 실시 후 78.72로 3.07 낮아졌으며 0.10수준으로 차이가 있었다. 간이정신진단검사 결과 신체화의 경우 원예치료 실시 전 51.55에서 실시 후 42.18로 9.37 낮아졌으며 0.10수준으로 개선되었다. 원예치료평가표(KHY)의 경우 정서적 발달, 사회적 발달 모든 항목에서 0.05 수준의 유의한 차이가 있었다. 특히 정서적 발달에서는 활동의욕, 충동억제, 집중력, 자주성, 성취감, 작업태도에서 높게 나타났으며, 사회적 발달에서는 도덕성과 협조성, 참여도에서 높게 나타났다. 이상의 결과로부터 원예치료가 혈압, 맥박 및 정서적 안정에 영향을 미치는 것으로 나타났다. 향후 대상 자에게 적합한 프로그램으로 체계적이고 지속적인 원예치료를 적용한다면 정신분열병 환자의 증상감소 및 정서적 안정은 물론 사회적 기능면에서도 크게 향상될 것이라 기대한다.
