Purpose: The purpose of this study was to identify the effects of aromatherapy on blood pressure and stress responses of clients with essential hypertension. Method: There were fifty-two subjects divided into an essential oil group, placebo group, and control group by random assignment. The application of aromatherapy was the inhalation method of blending oils with lavender, ylangylang, and bergamot once daily for 4 weeks. To evaluate the effects of aromatherapy, blood pressure and pulse were measured two times a week and serum cortisol levels, catecholamine levels, subjective stress, and state anxiety were measured before and after treatment in the three groups. Data was analyzed by repeated measures of ANOVA, one-way ANOVA, and $X^2-test$ using the SPSS 10.0 program. Results: The blood pressure, pulse, subjective stress, state anxiety, and serum cortisol levels among the three groups were significantly statistically different. The differences of catecholamine among the three groups were not significant statistically Conclusion: The results suggest that the inhalation method using essential oils can be considered an effective nursing intervention that reduces psychological stress responses and serum cortisol levels, as well as the blood pressure of clients with essential hypertension.

Objective: The aim of this experiment was to investigate the effect and the mechanism of Geumgoeshingi-whan (GGSGW) Pharmacopuncture at the acupoint GV 4 on the blood pressure in spontaneously hypertensive rats (SHR). Methods: SHR were injected with normal saline solution (Control-SHR group)or GGSGW Pharmacopuncture (GGSGW-SHR group) at the acupoint GV 4. The systolic arterial blood pressure and renal parameters were measured for two weeks. Results: The systolic arterial blood pressure was decreased significantly after GGSGW Pharmacopuncture at the acupoint GV 4 in SHR, followed by a significant rise in creatine clearance. The plasma levels of aldosterone were decreased significantly after GGSGW Pharmacopunctureas were the plasma levels of atrial natriuretic peptide (ANP). Conclusion: These results suggest that the blood pressure was decreased significantly after GGSGW Pharmacopuncture at the acupoint GV 4 in SHR and that the depressor response of the blood pressure was related to decreases in the plasma levels of aldosterone and ANP.

Sprague-Dawley(SD) rats were orally administered with $N^G$-nitro-L-arginine methyl ester(L-NAME) which inhibits or blocks the production of nitric oxide from L-arginine in vascular endothelial cells and vessel tissue to statistically examine the effects of nitric oxide on some physiological changes such as blood pressure and heart rate, and to confirm the apoptosis induced by the suppressed nitric oxide activity in some related organs under light microscope. Systolic blood pressure significantly increased 28.5% by the chronic treatment of L-NAME for 8 weeks (P<0.001), no significant difference, however, was observed in heart rate between the control group and the L-NAME-treated group regardless of their age. Hematoxylin-eosin staining showed some histological alterations only in kidney among the examined organs; heart, liver, pancreas, and adrenal gland from the L-NAME-treated group. TUNEL (terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling) test showed a strong positive reaction, representing that the chronic treatment of L-NAME facilitates apoptosis, in the cortex and medulla of kidney, but not any significance detectable in the other organs. These results conclude that chronic treatment of L-NAME significantly increases blood pressure, and that the followed inhibition of nitric oxide synthesis occurs a typical inducement of apoptosis in kidney.

The main purpose of this study was to evaluate the effect of a Rhythmical Exercise Program(REP) on physiological functions such as muscle strength, blood pressure, pulse, flexibility and body fat in the elderly. The research employed a non-equivalent control group pre-post test quasi experimental design. REP consisted of 45 minutes of dance, 3 times a week for 10 weeks. The formulated hypothesis were examined using the non-parametric statistics; Wilcoxon Signed rank sum test and Mann-Whitney test. The results are as follows; 1. The upper muscle strength and lower muscle strength of the experimental group were significantly higher than those of the control group following the REP(P<.0 5). And the Period of REP affected the muscle strength; the longer the exercise period, the stronger the muscle strength became. 2. The systolic blood pressure of the experimental group was significantly lower than that of the control group following the REP(p<.05). But there was no significant difference in the diastolic blood pressure between the experimental and control groups. The period of REP affected only systolic pressure; the longer the exercise period, the lower the systolic pressure became. 3. There was no significant difference in heart rate between the experimental and control groups, following the exercise period. 4. The flexibility of the experimental group was significantly higher than those of the control group following the REP(p<.01). And the period of REP affected flexibility; the longer the exercise period, the higher the flexibility(p<.05) became. 5. There was no significant difference of body fat between the experimental and control groups. The body fat of the experimental groups was significantly lower only 10 weeks after exercise(p<.01). Based on these results, it is suggested that rhythmical exercise program improves muscle strength, systolic pressure, and flexibility in the elderly.

Background: Korean Red Ginseng (Panax ginseng) has been shown to exert antihypertensive effects. In particular, ginsenoside Rg3 is thought to be a potent modulator of vascular function. The present study was performed to examine the antihypertensive efficacy of Korean Red Ginseng (KRG) extract and Rg3-enriched KRG (REKRG) extract. Methods: Spontaneously hypertensive rats (SHRs) andWistar-Kyoto rats (WKYs) were divided into six groups (WKY control, WKY-KRG, WKY-REKRG, SHR control, SHR-KRG, and SHRREKRG), and systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured at the carotid artery, followed by injection of 3mg/kg KRG or 3mg/kg REKRG. Results: REKRG treatment significantly decreased SBP and DBP 3hours post-treatment in the SHR group compared with SHR control group. However, SBP and DBP were not significantly different in KRG-treated SHRs compared with control SHRs. REKRG treatment did not significantly alter SBP or DBP 3hours post-treatment in the WKY group compared with WKY control group. Similarly, there were no differences in SBP or DBP with KRG treatment in the WKY group and WKY control group. Both KRG and REKRG increased endothelial nitric oxide synthase phosphorylation levels in the aorta, and the increases in endothelial nitric oxide synthase phosphorylation levels by REKRG treatment were higher than those with KRG treatment. Similarly, nitric oxide production in plasma from WKYs and SHRs was also increased by both KRG and REKRG. Conclusion: These results suggest that REKRG has a more beneficial effect on blood pressure control than KRG in SHRs.

The purpose of this study is to observe the relationship between smoking and control factors to blood pressure, such as sodium and potassium levels of dietary intake and serum in 67 rural university male students(smoker: 35 persons, non smoker: 32 persons). 3-day dietary record and blood sampling were conducted for measurements of the levels of dietary intake and serum. The results were as follows: 1) There are no significance between smokers and non-smokers in height, weight, and BMI. 2) Mean systolic and diastolic blood pressure of smokers and non-smokers were $131.33\pm93.75mmHg, \;119.37\pm80.62mmHg, $ respectively. Blood pressure of smoker was higher than that of non-smokers(p＜0.05). 3) There was no significant difference between smoker and non smoker in dietary potassium intake but dietary sodium intake and Na/K ratio of smoker were higher than those of non-smokers(p＜0.05, p＜0.05). And significant correlation was found between dietary sodium intake and blood pressure of smokers(p＜0.05). 4) Smokers of optimum gustation of salt(0.52%) was higher than that of non-smokers(0.49%). Even though blood pressure of smokers was not critical level, if they smoke continuosely until middle age, their blood pressure will be increased by smoking. The results of this study suggest that no smoking education program for smokers including the information about desirable food habits for prevention of hypertension should be developed.

While there are persistent rumors that the consumption of goat meat dishes increases blood pressure, there is no scientific evidence to support this. Two experiments were conducted to clarify whether or not blood pressure increases in conjunction with the consumption of goat meat dishes. In experiment 1, 24 Dahl/Iwai rats (15 weeks old, body weight $309.3{\pm}11.1$ g) were evenly separated into 4 groups. The control group (CP) was fed a diet containing 20% chicken and 0.3% salt on a dry matter basis. The goat meat group (GM) was fed a diet containing 20% goat meat and 0.3% salt. The goat meat/salt group (GS) was fed a diet containing 20% goat meant and 3% to 4% salt. The Okinawan mugwort (Artemisia Princeps Pampan)/salt group (GY) was fed a diet containing 20% goat meat, 3% to 4% salt and 5% of freeze-dried mugwort powder. The experiment 1 ran for a period of 14 weeks during which time the blood pressure of the animals was recorded. The GS, and GY groups consumed significantly more water (p<0.01) than the CP and GM groups despite the fact that their diet consumption levels were similar. The body weight of animals in the CP, GM, and GS groups was similar while the animals in the GY group were significantly smaller (p<0.01). The blood pressure in the GM group was virtually the same as the CP group throughout the course of the experiment. In contrast, while the blood pressure of the animals in the GS and GY group from 15 to 19 weeks old was the same as the CP group, their blood pressures were significantly higher (p<0.01) after 20 weeks of age. The GY group tended to have lower blood pressure than the GS group. In experiment 2, in order to clarify whether or not the increase in blood pressure in the GS group and the GY group in experiment 1 was caused by an excessive intake of salt, the effects on blood pressure of a reduction of salt in diet were investigated. When amount of salt in the diet of the GS and GY group was reduced from 4% to 0.3%, the animal's blood pressure returned to normotensive. These results indicate that, as in the case of chicken consumption, prolonged consumption of goat meat does not cause increased blood pressure, rather the large amount of salt used in the preparation of goat meat dishes is responsible for the increase in blood pressure.

In oriental medicine, Gamibangpungtongsungsan (KBTS) has been used as a therapeutic agent for the treatments of acute stage of cerebrovascular diseases and hypertension. In the present study, underlying mechanism on KBTS effects was investigated using spontaneously hypertensive rats (SHR) by determining related parameters such as blood pressure, heart-beat rates, and hormones and plasma constituents. The major finding are summarized as follows. 1. KBTS treatment at concentrations lower than $125\;{\mu}g/m{\ell}$ did not show any cytotoxicity on cultured human fibroblast cells. 2. KBTS treatment in SHR significantly decreased blood pressure and heart-beat rate compared with untreated control. 3. KBTS treatment in SHR decreased aldosterone levels in the blood compared with untreated control, but the difference was not statistically significant. 4. KBTS treatment in SHR significantly decreased dopamine, norepinephrine and epinephrine levels in the blood compared with untreated control. 5. KBTS treatment in SHR decreased plasma ion concentrations such as Na+, K+, Ca2+, Cl- compared with untreated control; decreases in Na+ and Cl- were statistically significant. 6. KBTS treatment in SHR significantly decreased TNF-$\alpha$, IL-6, and IL-10 levels in the blood compared with untreated control. Thus, the present data show evidence on anti-hypertension activity of KBTS in an experimental animal system, which can provide further insights into the development of anti-hypertension therapeutic agents.

Purpose: This study was done to examine the effects of abdominal breathing on VAS-Anxiety (VAS-A), blood pressure, peripheral skin temperature and saturation oxygen in pregnant women in preterm labor. Method: The study design was a matched control group interrupted time series. Forty-six women matched to gestational age were assigned to either the experimental group (26) or control group (20). Data were collected between March 2007 and May 2008. For the experimental treatment the women performed abdominal breathing 30 times, which took 5 minutes, and did one set of 5-minute abdominal breathing daily for three days. Data collection was done before and after the abdominal breathing to measure VAS-A, blood pressure, peripheral skin temperature and oxygen saturation. Descriptive, $X^2$, Mann-Whitney U tests were used to analyze the data with the SPSS/PC+Win 15.0 program. Result: For the experimental group there were significant decreases in VAS-A (Z=-4.37, p=.00), systolic blood pressure (Z=-3.38, p=.00), and an increase in skin temperature (Z=-4.50, p=.00) and oxygen saturation (Z=-3.66, p=.00). Conclusion: These findings suggest that abdominal breathing in pregnant women in preterm labor results in decreases in anxiety(VAS-A) including biological evidences such as systolic blood pressure, and increases in peripheral skin temperature and oxygen saturation. Further longitudinal study is needed on the lasting effects and obstetric and neonatal outcomes following abdominal breathing.

In order to evaluate the effect of habitual Na and Ca intake on blood pressure regulation, we measured the habitual dietary intakes of Na and Ca, urinary excretion of Ca, Na and K, and plasma level of renin activity, aldosterone, and indices of Ca metabolism in 27 untreated hypertensive women and 30 age-matched normal women on a free diet. Hypertensive and total subjects were divided into four groups according to habitual dietary intakes of Na and Ca as low Na-low Ca(LNLC), low Na-high Ca(LNHC), high Na-low Ca(HNLC), and high Na-high Ca(HNHC). HNLC hypertensive group showed the lowest level of plasma renin activity, 25-(OH) Vit D$_3$, calcitonin and serum total Ca, and presented the highest level of PTH and urinary excretions of Na/K and Ca/Cr. There were no significant difference in plasma level of aldosterone and urinary excretion of Na and K among four hypertensive groups. When all subjects were divided into four groups according to the same method, HNLC group showed the highest level of blood pressure with no statistical significance and the lowest level of calcitonin and total serum Ca. The above results indicated that renin-aldosterone system and Ca regulating hormone has a mutual relationship in hypertension. Na and Ca may interact each other, rather than affecting independently blood pressure control. As a result, considering the fact that daily balance of Na and Ca intakes affects Na and Ca regulating hormones and urinary excretion of Na and Ca, it may be involved in blood pressure control. These results suggest that maintaining an adequate intake of Ca with less intake of Na may prevent from the risk of hypertension. (Korean J Nutrition 34(4) : 409~416, 2001)
