In order to investigate the antihypertentive effects and its mechanism of the Siegesbeckia pubescens aqua-acupuncture treatment, experiments were performed on immediate and continuous antihypertensive effects, vasodilatation-autonomic nerve block, diuretic activity, and angiotensin converting enzyme inhibitory activity. The results were as follows; 1. Acupuncture treatment group showed significantly immediate antihypertensive effects in 4 hours after treatment. Normal saline aqua-acupuncture treatment group showed significantly immediate antihypertensive effects in 2, 4 and 6 hours after treatment. Siegesbeckia pubescens aqua-acupuncture treatment group showed significantly immediate antihypertensive effects in 30 minutes, 1, 2, 4 and 6 hours after treatment. 2. Siegesbeckia pubescens aqua-acupuncture treatment group showed significantly continuous antihypertensive effects in 6, 8, 9 and 10 days after treatment. 3. Siegesbeckia pubescens aqua-acupuncture extract solution showed significantly vasodilatatory and sympathetic nerve block effects with concentration of $10^{-6},\;10^{-5},\;10^{-4},\;10^{-3}g/m{\ell}$. 4. Oral administration group of the Siegesbeckia pubescens aqua-acupuncture extract solution didn't show no significantly diuretic effects. 5. Siegesbeckia pubescens aqua-acupuncture extract solution showed 28.8% angiotensin converting enzyme inhibitory activity.

Objectives : The main objectives of this study are to identify the factors associated with hypertension control and to determine the influencing factors associated with antihypertensive therapy. Methods : The study was conducted on 107 subjects who participated in the 1999 and 2002 Gwacheon Study and who had had uncontrolled hypertension (systolic$\geq$140 or diastolic$\geq$ 90mmHg) in 1999, We compared the characteristics of the controlled and uncontrolled hypertensive group and investigated the characteristics of those taking antihypertensive medication. Univariate associations between hypertension control and its characteristics and the association between antihypertension treatment and its characteristics were tested with $x^2$-test. We also peformed logistic regression analysis. Results : The participants who had their blood pressure checked within 6 months before their first measurement and those who had taken the antihypertensive medication showed significantly better hypertension control during the follow-up. The multivariate analysis showed that baseline antihypertensive therapy was the most important determinant factor of hypertension control during the follow-up. Socioeconomic level and life style did not affect hypertension control when controlled by the treatment variable in this study. The factors associated with antihypertensive therapy at follow-up were previous antihypertensive therapy, old age, and high educational level. Conclusions : Those who received antihypertensive therapy and those who had their blood pressure re-checked within 6 months both showed well controlled hypertension. The subjects with high educational level complied well with the antihypertensive regimen, but those in their forties did not.

Whereas systolic blood pressure (SBP) continuously rises with age, diastolic blood pressure (DBP) gradually decreases after the age of 55 years. Therefore, hypertension in the elderly shows the pattern of isolated systolic hypertension. There is evidence on the benefits of controlling blood pressure (BP) in elderly patients with hypertension. The BP lowering effect has also been demonstrated in patients over 80 years of age with hypertension. The BP threshold for the initiation of antihypertensive drug treatment for older adults with hypertension is gradually decreasing. The antihypertensive treatment is recommended if, despite therapeutic lifestyle modifications, SBP ≥140 mmHg or DBP ≥90 mmHg in those aged 65-79 years old, and SBP ≥140-160 mmHg or DBP ≥90 mmHg in those aged ≥80 years old. Although there is no consensus on the target BP for older adults with hypertension, a target SBP of <130-140 mmHg and DBP of <80-90 mmHg are recommended. In older adults over 80 years of age with hypertension, the target SBP is <140-150 mmHg. When the dose of antihypertensive drugs is increased to reach the target SBP, DBP may decrease to less than 70 mmHg, but it should not be <60 mmHg. Thiazide diuretics, calcium channel blockers, angiotensin-converting enzyme inhibitors, or angiotensin receptor blockers can be selected as the first-line drug for older adults with hypertension. Beta-blockers may be selected in case of compelling indications.

Purpose: The purpose of this study was to identify the attributes of the concept, of psychological resistance to antihypertensive medication. Methods: The study was conducted in accordance with Walker and Avant's conceptual analysis process. We reviewed 47 related studies selected from 4 international and Korean databases including Medline, CINAHL, NDSL, and RISS to perform the analytical processes from January 1980 to September 2015. Results: The attributes of psychological resistance to antihypertensive medication include 1) reservation, 2) opposition, 3) denial, 4) refusal, and 5) seeking alternative therapy. The antecedents of the concept can be classified into patient factors such as reactance trait and knowledge deficit, provider factors, interpersonal factors, and environmental factors. The consequences of psychological resistance to antihypertensive medication are non-compliance, deterioration of the disease, developing complications, increased anxiety, and changes in life. Conclusions: The concept of psycho logical resistance to antihypertensive medication can provide guidance for the development of an intervention program that promotes the compliance to medication regimen of hypertensive patients. Further research needs to be done to develop a measurement tool for psychological resistance to antihypertensive medication.

Objectives : The purpose of this study was to review the clinical studies on antihypertensive effects of Oryeong-san. Methods : We searched papers using KTKP, Oasis, CNKI, PubMed, Embase, Science Direct, CINAHL, J STAGE and CiNii, and the key words "Oryeong-san (韓)", "Wuling-san (中)", "Gorei-san (日)", and "Hypertension" were used. Search range included randomized controlled trials (RCTs), clinical reports, reviews and animal experiments. Papers not matched with inclusion criteria were excluded. Results : A total 479 studies were found, with 457 excluded during title and screening. After scanning 22 papers, a final 3 RCTs and 6 case reports were selected and analyzed. In the 3 RCTs, the number of patients varied between 65 and 156. Patients with hypertension were randomized into groups for treatment group and control group. They were all treated with antihypertensive drugs (Vamlodipine Besylate, Benazepril, Perindopril); the treatment group was also given modified Oryeong-san. After treatment, results were that blood pressure was significantly decreased in the treatment group, compared to the control. The other 6 case reports reported that modified Oryeong-san alone or the combination of Oryeong-san plus antihypertensive drugs had beneficial effects on blood pressure. Conclusions : Oryeong-san appears to be effective in improving blood pressure and hypertension-related symptoms. The results of this study could be applied to clinical treatment of hypertension. Further large-scale clinical researches should be conducted.

The antihypertensive effects of the Wild Mountain Ginseng Cultured Root Extract (WMGCE) were investigated in spontaneously hypertensive rats (SHR). Daily oral administration of the WMGCE (100 and 200 mg/kg) exhibited a significant decrease in blood pressure in SHR rats during for 8 weeks. The systolic blood pressure was dose- and time-dependently decreased significantly from the second weeks (p < 0.05) to the end of WMGCE treatment in SHR. The WMGCE decreased the plasma levels of sodium, potassium, chlorides, urea and osmolarity in SHR rats but no statistically significant change was observed. Furthermore, no significant changes were noted on heart weight, heart rate and diameter of aorta after WMGCE treatment in SHR. Our results suggest that daily oral administration of WMGCE at the dose of 100 and 200 mg/kg for 8 weeks exhibited antihypertensive activities.

Background: Fixed drug combinations are formulations containing two or more active ingredients in a single dosage form. Such combination therapies are commonly applied to improve efficacy, reduce adverse events and replace co-administration, etc. National and international guidelines for hypertension treatment recommend addition of other classes of antihypertensive drugs rather than incremental dose of mono-therapy, when blood pressure is not adequately controlled. Thus, many dual combinations of antihypertensive drugs have been approved and pharmaceutical companies are recently interested in developing antihypertensive triple combinations. Clinical trial designs for the fixed combinations are various depending on the target patients, dosage and clinical endpoints. Thereby, further discussions for the clinical trials of antihypertensive triple therapies are required regarding the indication claimed. Conclusion: This article provides a review for the assessment of the label and medical reports of the clinical trials on antihypertensive triple therapies in advanced foreign countries.

Background: Hypertension is a major contributor to the global disease burden of cardiovascular and cerebrovascular disease. The aim of this study was to determine demographic and clinical factors associated with adherence to antihypertensive medication. Methods: From August 2012 to February 2015, we recruited 1,523 Korean patients with hypertension who visited family physicians. The study was conducted in 24 facilities located in urban and metropolitan areas. Of these facilities, two were primary care clinics and 22 were level 2 or 3 hospitals. Adherence was assessed using the pill count method; a cut-off value of 80% was used as the criterion for good adherence. Sociodemographic and lifestyle factors were compared between the adherent and nonadherent groups using the chi-square test for categorical variables and t-test for continuous variables. Binary logistic regression analysis was performed with medication adherence as the outcome variable. Results: Of the 1,523 patients, 1,245 (81.7%) showed good adherence to antihypertensive medication. In the multivariate logistic analysis, age ${\geq}65$ years, exercise, treatment in a metropolitan-located hospital, being on ${\geq}2$ classes of antihypertensive medication and concomitant medication for diabetes, and a family history of hypertension or cardiovascular diseases were associated with good adherence. Patients who had a habit of high salt intake were less adherent to medication. Conclusion: Multiple classes of antihypertensive medications, concomitant medication, and exercise were associated with good adherence to antihypertensive medication, and high salt intake was associated with poor adherence to antihypertensive medication. These factors should be considered to improve hypertension control.

Objectives: The aim of this study was to review the clinical research on antihypertensive effects of Korean herbal medicines that function by inducing diuresis. Methods: Literature searches were performed using PubMed, Cochrane, CNKI, Wanfang, Cinii, Oasis, KISS, NDSL, RISS, DBPia, with the keywords "利水", "利尿", "高血壓", "hypertension", and "lishui." The search range included only randomized controlled trials that verified the effects of Korean herbal medicine interventions on hypertension. The selected studies were assessed by risk of bias (RoB). Results: 26 reports were selected from a total of 532 identified. For these reports, meta-analysis was performed using Revman 5.3. From this analysis, it was observed that the combined treatment of Korean medicine and antihypertensive drugs had a significantly higher total effective rate (TER) and improvement in systolic blood pressure (SBP) and diastolic blood pressure (DBP) than did the use of a single antihypertensive drug. The risk ratio of TER for lowering blood pressure was 1.25. The mean differences of SBP, DBP were -19.63 mm Hg (95% confidential interval (CI), -22.45 mm Hg, -16.80 mm Hg, p<0.00001), and -5.39 mm Hg (95% CI, -7.36 mm Hg, -3.42 mm Hg, p<0.00001) respectively. The use of Korean medicine only did not improve blood pressure, as compared to the use of an antihypertensive drug. Most of items of RoB were unclear, and the methodological quality was low. Conclusions: The combination of antihypertensive drugs and Korean medical treatment can effectively improve SBP, DBP, and TER. This finding could be widely utilized in clinical practice in Korean medicine.
