  • Various kinds of related parameters on hypertension such as anti-oxygen effect, ACE, weight of body, hwart and kidney, blood pressure, heartbeat rates, contents of aldosterone, catecholamine, change rates, of plasma constituents, uric acid, BUN, creatinine were determined to verify the effects on hypertension by Kamisamul-tang (KSMT). And the results are concluded as follows. KSMT did not show any cytotoxicity at the range of concentration (1-250 ${\mu}g/m{\ell}$) on the human fibroblast cell (hFCs). KSMT decreased the production of reactive oxygen species (ROS) and DPPH generation depending on the concentration. KSMT significantly inhibited angiotensin converting enzyme(ACE) activity depending on the concentration compared with control. KSMT maintained body weight of body, heat and kidney nearly normal group in hypertensive rat induced by DOCA-salt. KSMT significantly blood pressure and heart beat rate compared with control in hypertensive rat induced by DOCA-salt. KSMT significantly decreased aldosterone, dopamine, norepineph- rine, epinephrine compared with control in hypertensive rat induced by DOCA-salt. KSMT significantly decreased the level of potassium and cloride compared with control wheareas increased that of calcium significantly in hypertensive rat induced by DOCA-salt. KSMT significantly decreased the level of uric acid and BUN compared with control in hypertensive rat induced by DOCA-salt. It is verified experimentally tat Kamisamultang(KMST) which has been used broadly as a clinical therapeutics in oriental medicine is effective for anti-hypertension mechanism. And it could be applied to develope the reliable prescriptions for anti-hypertension in the future.

  • Objectives: The purpose of this study is to confirm the effectiveness and safety of herbal medicine treatment for treating pregnancy-induced hypertension. Methods: We searched for randomized controlled trials of pregnancy-induced hypertension treated with herbal medicine, through nine databases. Interventions and results of the selected clinical studies were analyzed. Results: Eleven randomized controlled trials were finally included according to the inclusion and exclusion criteria. Treatment group was treated with herbal medicine alone in two studies, and with herbal medicine and western medicine in nine studies. Control group was treated with western medicine. Taxilli Ramulus (桑寄生) (54.5%) was the most frequently used herb in herbal medicine treatment. In all of eleven studies, treatment group was more effective for pregnancy-induced hypertension than the control group. Conclusions: This study suggested that herbal medicine treatment alone or combined with western medicine treatment could be helpful in improving the therapeutic effect on pregnancy-induced hypertension and reducing side effects as well. However, in order to obtain stronger evidence of herbal medicine treatment for pregnancy-induced hypertension, more high-quality and well-designed randomized controlled trials should be conducted.

  • Objectives : High-normal blood pressure' is a factor influencing decision to initiate targeted intensive intervention strategy in westernized populations. JNC-VI offered the vigorous lifestyle modification for persons with 'high-normal blood pressure', who could be early detected. As a hypertension seems to be the result of multiple genetic factors operating in concert with associated environmental factors, it will be necessary to identify the high-normal blood pressure as a risk factor of hypertension for applying primary prevention strategy in Korean people. Methods : Although cohort study design might be adequate to recruit incidence cases, to keep time sequence of events, and to prevent information bias, nested case-control study was chosen for avoiding measurement errors because hypertension is a benign disease. Source population was the 'Seoul Cohort' participants and follow-up was done by using Korea Medical Insurance Corporation's database on the utilization of health services from 1 Jan93 to 30Jun97. Incidence cases were ascertained through the chart review, telephone contacts, and direct blood pressure measurements. Controls included the pairing of 4 individuals to each case on the basis of age. Results : As 75% of 247 incident cases had high-normal blood pressure, the crude odds ratio for hypertension was 2.04 (95% CI 1.47-2.83). Another statistically significant risk factors of hypertension were body mass index, dietary fiber, alcohol consumption, weekly activity and history of quitting smoking. The multivariate odds ratio of high-normal blood pressure adjusted for all risk factors was 1.84 (95% CI 1.31-2.56). Among high-normal blood pressure group, body mass index, weekly ethanol amounts, weekly physical activity, and dietary fiber except history of quitting smoking were still risk factors of hypertension. Conclusion : 'High-normal blood pressure' is a risk factor for hypertension in Korean middle-aged men, which represents that the vigorous lifestyle modification for persons with 'high-normal blood pressure' is need.

  • Pathophysiological implications of the vascular nitric oxide (NO)/cGMP pathway in hypertension were investigated. Sprague-Dawley rats were made deoxycorticosterone acetate (DOCA)-salt hypertensive for six weeks. The protein expression of endothelial constitutive NO synthase (ecNOS) and the tissue content of NO were determined in the thoracic aorta. The protein expression and catalytic activity of soluble guanylyl cyclase (GC) were also determined. Systolic blood pressure measured on the day of experiment was significantly higher in the experimental group than in the control. The hypertension was associated with decreases in the vascular tissue content of NO metabolites, concomitantly with the expression of ecNOS proteins. The protein expression of GC was not affected, while its catalytic activity was significantly decreased in hypertension. These results indicate that the high blood pressure is associated with a decreased activity of vascular NO/cGMP pathway in DOCA-salt hypertension.

  • The kallikrein-kinin system affects regulation of blood pressure, and genes encoding for the components of this system have been considered as good candidates for hypertension. To evaluate the relationship between genetic polymorphisms of candidate genes involved in this system and hypertension, we performed case-control studies using genetic markers in Korean normotensives and hypertensives, respectively. By association study, there was a marginal association with hypertension in AA genotype distribution of A1789G polymorphism in the hKLK1 gene (P=0.0754). Thus, this genetic polymorphism may weakly contribute to the susceptibility to hypertension in Koreans. We also observed that significant linkage disequilibrium exists among three polymorphic sites in the hKLK1 gene studied, suggesting that the three genetic polymorph isms can be useful as genetic markers in clinical association studies. Further studies using larger sample sizes and more genetic markers will be needed to clarify genetic influence of kallikrein-kinin system for hypertension.

  • Noncompliance with treatment is a serious problem in the management of hypertension. We explored self-reported medication taking compliance behavior of 194 high blood pressure patients using modified health belief model hypothesizing interaction between model components. Data were collected from patients resistered hwachon community hypertension control program during February, 1993. Bivariate analysis showed perceived severity of complication, present symptom experience(p<0.05), perceived severity of hypertension and education leve(p<0.01) were significantly related to treatment experience. Logit analysis revealed that perceived severity of hypertension, perceived benefits of treatment, perceived barriers to treatment and interaction term between perceived severity of hypertension and perceived benefits of treatment contributed treatment experience. Health education from mass media was siglificantly related to continuity of treatment. We also concluded that the inclusion of interaction effects between health belief model components and the use of patient group as analysis unit lead to better study results.

  • The purpose of this study was to examine the effects of health program s on hypertension in a public health center located in Y-si. Most interesting were the effects on hypertension-related knowledge, self-care behavior, quality of life, and physiological parameters for hypertensive patients. Nonequivalent control group pretest-posttest design was employed. A total of 48 patients with hypertension living in Y-si were assigned to either the experimental group (n=23) or the control group (n=25). The experimental group was provided with an 8-week health program on hypertension between August 31 and October 23 in 2015. Data were analyzed with SPSS/WIN 21.0 using descriptive statistics, ${\chi}^2$-test, Fisher's exact test, and t-test. The result indicated a significant difference between the experimental group and the control group with respect to the scores of hypertension-related knowledge (t=-3.76, p<.001), self-care behavior (t=-3.33, p=.002), physiological parameters, including systolic blood pressure (t=6.27, p<.001) and diastolic blood pressure (t=4.70, p<.001), total cholesterol levels (t=3.08, p=.003), and Abdominal circumference (t=2.52, p=.015). We conclude that the self-group program on hypertension has a significant effect on the change of hypertension-related knowledge and self-care behavior for hypertensive patients.

  • [Purpose] The purpose of this study was to assess changes in blood glucose level, blood pressure, and arterial stiffness after a 75 g oral glucose tolerance test (OGTT) in elderly women aged over 65 years with hypertension and either normal glycemic control, impaired fasting glucose tolerance, or diabetes mellitus. We also wished to investigate the relationship between stages of diabetes and physical fitness. [Methods] A total of 24 elderly women with hypertension were assigned to a control group (CON; n=7), impaired fasting glucose group (IFG; n=9), and diabetes mellitus group (DM; n=8). In each group, blood glucose level, brachial ankle pulse wave velocity (PWV), and blood pressure were measured at baseline as well as 60 and 120 minutes after a 75 g OGTT. Physical fitness factors such as hand grip strength, balance test, 4 m gait speed test, chair stand test, short physical performance battery, and 6-minute walking test were subsequently assessed. [Results] In all three groups, blood glucose levels were significantly increased at 60 and 120 minutes after a 75 g OGTT. In the DM group, blood glucose levels were significantly higher before and after a 75 g OGTT than in the CON group. In the CON group, PWV was significantly increased at 60 minutes after a 75 g OGTT; however, there were no changes in other groups after glucose ingestion. In the CON group, systolic and diastolic blood pressures were significantly decreased at 60 and 120 minutes after a 75 g OGTT compared to baseline. However, there was no change in blood pressure after ingestion in the DM group. The IFG group had greater grip strength than the CON group; however, there were no differences in other variables between the groups. [Conclusion] After a 75 g OGTT, elderly women with hypertension and diabetes maintain higher blood glucose levels compared to those with hypertension alone. Unlike elderly women with hypertension alone, those with hypertension and diabetes did not show changes in arterial stiffness and blood pressure after a 75 g OGTT. Therefore, elderly women with hypertension and diabetes may not be able to control their blood vessels following a 75 g OGTT due to impaired vascular endothelial function. Moreover, there was no association between diabetes stage and physical fitness in elderly women with hypertension.

  • To access the safety and efficacy of Chungyeoldodam-tang(CDT), a traditional herbal medicine prescription, on hypertension we examined various parameters involved in the pathogenesis of hypertension. CDT seems to be safe because CDT at the concentrations lower that 250 ug/ml showed no toxic effects in cultured human fibroblast and no toxic effects on liver function. The production of reactive oxygen species (ROS) were greatly decreased in CDT treated group compared with control, and angiotensin converting enzyme activities were reduced by CDT in a dose dependent manner. There was no differences in weight of hearts between control and CDT treated group. The blood pressure and pulse rate were significantly decreased. CDT greatly reduced the levels of plasma hormones including aldosterone, dopamine, and norepinephrine, but not epinephrine, and serum electrocytes including Na$^+$ and Cl$^-$, but not K$^+$. were also decreased. The levels of uric acid, BUN and creatinine were significantly decreased compared with control. These results suggested that CDT has suppressive effects on various pathologic factors in hypertension, and CDT has potential as a safe and effective therapeutics for hypertension.

  • Purpose: This study was conducted to compare health-related characteristics and self-care behavior between a controlled group and a non-controlled group of hypertension patients in a customized home visiting health service. Methods: This study was conducted as cross-sectional research. The subjects were 1,317 hypertension-controlled patients and 555 non-controlled ones. Data were collected using a structured questionnaire and analyzed by descriptive statistics, $x^2$-test, and t-test using the SPSS WIN 15.0 program. Results: Sociodemographic characteristics and self-care behavior were not significantly correlated between the groups. According to health-related characteristics, the health status was significantly higher in the hypertensioncontrolled group than in the non-controlled group. The cholesterol level was significantly lower in the hypertension-controlled group than in the non-controlled group. Conclusion: Attention should be paid to patients who are not in good health status in order to control their hypertension. Also, it is necessary to educate the patients in order for them to manage their hypertension and cholesterol.
