The purpose of this study is to show that, before registration of chronic degenerative diseases and enforcing management system in health centers, the management of hypertension could achieved comprehensively and continuously by knowing the realities of drug-taking and its related factors those who are being cared for in health centers. For one year, a questionnaire about drug-taking realities of hypertensive patient was distributed at 8 health centers in Taegu from March 24. 1997 to April 24. 1997. The questionnaires were then collected and analysed. The results are as follows: Of 691 patients, 77.4% of patient were taking medicine regularly every day. The reasons why patients weren't taking medicine every day was as follows: the blood pressure became normal(34%, the highest of the group), patients forgot(28.2%), it was difficult to buy the medicine(15.4%), there was no effect even though the patient took medicine continuously. The experience of medical treatment outside of health centers was 28.9%. The types and percentages of alternative medicine are herbs (50.5%), health food(24.5%), folk remedy(13.7%). Among them, 44.6% of patients didn't know if the medicine was effective. Medical treatment places excluding health centers was pharmacies(63.5%-the highest rate). In simple analysis, the older one was the more regularly one took the medicine, but there was no statistical relations. Of health activities, patients eating low-salt diet showed that they took the medicine regularly. Nonsmoking patients and those who experienced drug side-effect and those who doubted doctor's prescriptions and instructions showed that they took alternative, excluding modem medicine. Anti-hypertensive drug medication status according to recognition, attitude, experiences of hypertension showed that patients who thought that they should take anti-hypertensive drug during the whole life time took the medicine regularly(82.3%). The reasons for patients turning to alternatives varied. In case of having subjective symptom(34.1%), those who thought they knew the hypertension well(36.6%), they decided to use alternatives. In multiple logistic regression analysis the key statistics were as follows: The older patients, patients who ate low-salt diet, patients who thought that they should take anti-hypertensive drug during the whole life time, all showed that they took medicines regularly. And also patients who experienced drug side-effect, doubted prescriptions and instructions, and patients who had subjective symptoms, patients who thought that he knew the hypertension very well, all showed higher rate of using alternative medicine. In the future, at the health centers, to register and manage hypertension patients effectively, we must educate patients about regular drug-taking, and alternatives without doctor's prescriptions.

Background : Hypertension is treated with both lifestyle modification and pharmacotherapy. The Seventh Report of the Joint National Committee on Detection, Evaluation, and Treatment of High Blood Pressure (JNC-7), published in 2003, provides a streamlined management approach to hypertension for the primary care physician. The JNC-7 is the gold standard also in Korea. According to the JNC-7, special therapeutic considerations are recommended for high-risk individuals with compelling indications. The presence of compelling indications in any given patient should be considered when selecting specific pharmacotherapy to treat hypertension. However, in patients with compelling indications, it is unknown that hepatotoxicity is caused by Calcium Channel Blocker (CCB), one of 1st anti-hypertensive drugs. Now, the CCB is the most used 1st anti-hypertensive drug in Korea Therefore, we evaluated the changes in blood liver function parameters (ALT, AST, Total bilirubin, serum albumin) for the study group. Methods : We randomly collected and retrospectively analyzed Electronic Medical Record data (n=28,788) of patients, and who took calcium channel blockers(non-dihydropyridines; diltiazem, verapamil, dihydropyridines; amlodipine, barnidipine, benidipine, clinidipine, efonidipine, felodipine, isradipine, lacidipine, lercanidipine, nicardipine, nifedipine, nimodipine), with having liver function tests (LFTs) from July 1st 2009 to June 30th 2010 at the Seoul National University Hospital in Korea. Control groups are two antihypertensive agents: RAS blockade (ARB; candesartan, irbesartan, losartan, olmesartan, telmisartan, valsartan, ACE-I; cilazapril, enalapril, fosinopril, imidapril, perindopril, ramipril) and, Diuretics (loop; furosemide, torsemide, thiazide; hydrochlorothiazide[HCTZ], indapamide). Patients not having LFT results at these three standard points of time(baseline, during, medication, and after finishing medication) were excluded. The collected data were analyzed by using the SPSS (Version12.0) and Microsoft Excel (Version2007). Results : 711 patients who were treated CCB (297), RAS blockade (232) or Diuretics (182) monotherapy were selected for the study. In selected patients, liver damage degree(changes of each LFTs value) was higher in diuretics group than other groups, followed by RAS blockade and CCB. In diuretics group's was loop-diuretics group was higher than thiazide-diuretics group. In CCB group, Nondihydropyridine-CCB's damage degree was higher than Dihydropyrine-CCB's that. Conclusions : Despite the limitations due to the retrospective study, among patients with abnormal LFTs, the use of CCBs led to a less liver damage than other 1st anti-hypertensive agents. It can be recommended CCBs as one of the initial treatments of hypertension in patients with liver disease.

Background : Ginseng has traditionally been used in oriental countries to recover vital energy from Qi deficiency, and has shown various biomedical effects in the scientific literature. Recent reports suggest that ginseng could regulate blood pressure (BP), but much controversy still remains. Therefore, we intended to assess the anti-hypertensive effect of several ginseng types frequently used in clinics. We also investigated the anti-hypertensive effect on Koreans and Chinese, and by the body type according to Sasang Constitution Medicine (SCM). Methods : The study subjects were recruited from mildly hypertensive patients who exhibited pre-hypertension(120/80 to 139/89 mmHg) and stage I hypertension (140/90 to 159/99 mmHg) in Korea and China. After assigning the subjects into a Korean, a Chinese, a red, and an American ginseng group by randomization, we prescribed ginseng at a dose of 4.5 g per day for 4 weeks. To assess the anti-hypertensive effect, we compared the mean of systolic and diastolic BP between before and after ginseng medication using a 24-hour ambulatory blood pressure monitor (24 hr ABPM. We also monitored adverse effect and laboratory findings to secure the subjects' safety. In addition, all of the subjects in Korea consulted a specialist of Sasang Constitution Medicine to identify their constitutional type. Results : There were 64 subjects treated with Korean ginseng, 58 treated with Chinese ginseng, 33 treated with red ginseng, and 64 treated with American ginseng. Korean, Chinese, and American ginseng all reduced subjects' BP; Korean and Chinese ginseng showed more effect. The secondary analysis on the subjects' nationality revealed that all of the ginseng types showed more significant anti-hypertensive effect in Chinese patients than in Koreans. The third analysis on the constitutional type of SCM showed there was no significant difference in the effectiveness and the safety of ginseng among the constitutional types. Conclusions : We suggest ginseng, especially Panax ginseng without any steaming-drying process, could be useful for mild hypertension. Further, ginseng is safe regardless of subjects' constitutional type or type of ginseng within a dosage of 4.5g per day.

Ginseng has been traditionally used to recover vital energy from Qi deficiency in oriental countries. Recent reports suggested that ginseng could regulate blood pressure (BP), but much controversy still remain. Therefore, we intended to assess the anti-hypertensive effect of some ginseng species on Koreans and Chinese. This is a randomized, double blinded controlled clinical trial. The study subjects were recruited from the mild hypertensive patients who belonged prehypertension(120/80 to 139/89 mmHg) and stage I hypertension (140/90 to 159/99 mmHg) in Korea and China. After assigning the subjects into a Korean, a Chinese, and an American ginseng group by randomization, we prescribed ginseng with the dose of 4.5 g per a day for 4 w. To assess the anti-hypertensive effect, we compared the mean of systolic and diastolic BP between before and after ginseng medication by 24 h Ambulatory Blood Pressure Monitor (24 h ABPM). We also monitored adverse effect and laboratory findings to secure the subjects' safety. There were 64 subjects treated with Korean ginseng, 58 treated with Chinese ginseng, and 64 treated with American ginseng. All of the ginseng species reduced subjects' BP. Especially, Korean and Chinese ginseng showed more excellent effects. The secondary analysis on the subjects' nationality revealed that all of the ginseng species showed more significant anti-hypertensive effect in Chinese than in Koreans. We suggest ginseng could be useful for mild hypertension regardless of its species. And it would be safe within the dosage of 4.5 g per a day.

Objectives: Several studies have revealed that systemic hypertension is strongly associated with cataractogenesis. However, the pathophysiology and treatment is often unclear. In this study, we evaluated the anti-cataractogenic effect of cinnamaldehyde (CA), a natural organic compound, in rats with fructose-induced hypertension. Methods: The rats were divided into six groups. For six weeks, the normal group received a suspension of 0.5% carboxy methyl cellulose (10 mL/kg/day, p.o.) while five other groups received a 10% (w/v) fructose solution in their drinking water to induce hypertension. By the end of the third week hypertension had been induced in all the animals receiving fructose. From the beginning of the fourth week to the end of the sixth week, one of those five groups (control) continued to receive only 10% (w/v) fructose solution, one group (standard) received ramipril (1 mg/kg/day, p.o.) plus 10% (w/v) fructose solution, and three groups (experimental) received CA at doses of 20, 30, and 40 mg/kg/day p.o., plus 10% (w/v) fructose solution. Blood pressure was measured weekly using a non-invasive blood pressure apparatus. After six weeks, the animals were sacrificed, and the anti-cataractogenic effects on the eye lenses were evaluated. Results: Administration of fructose elevated both the systolic and the diastolic blood pressures, which were significantly reduced by CA at all dose levels. In the control group, a significant increase in the malonaldehyde (MDA) level and decreases in the total protein, $Ca^{2+}$adenosine triphosphate (ATP)ase activity, glutathione peroxidase, catalase, superoxide dismutase and glutathione levels, as compared to the normal group, were observed. Administration of CA at all doses significantly restored the enzymatic, non-enzymatic, antioxidants, total protein, and $Ca^{2+}$ATPase levels, but decreased the MDA level, as compared to the control group. Conclusion: The present study revealed that CA modulated the antioxidant parameters of the serum and lens homogenates in hypertension-induced cataractogenic animals.

Objectives : To describe health behaviors related to hypertension in rural population of Korea and focused to identify inappropriate awareness, treatment, and control of hypertension. Methods : We surveyed 5,517 adults (2,288 males, 3,229 females) older than 30 years in 58 rural areas, purposely sampled nationwide from December 1996 to February 1997. Blood Pressure was checked twice af the time of the first visit. For those who showed high blood pressure using the JNC-6 criteria at their initial visit, we followed up their blood pressure one week later. Also information on the health behavior related to hypertension was collected through the person-to-person interview using structured questionnaire at the first visit. Results : For the past one year, females had more experiences of checking their blood pressure than males (77.3% versus 69.5%, p=0.001). Through the results of consecutively checked blood pressure, only 51.7% of the hypertensives were aware of their condition. Of the hypertensives who aware of their condition, 44.4% did not receive any medication and/or recommendation. And 50.4% of the hypertensives who had anti-hypertensive medication were classified as still having hypertensive blood pressure by 160/95 mmHg criteria. Of the medicated, 54.8% were found to take medication regularly for the past six months. Among the medicated, only 11.4% knew the name of anti-hypertensive drug they had. Conclusions : 'Rule of halves', which works in the situation of no special efforts for hypertension control, was identified. This study showed that much efforts to control hypertension would be required in the rural population of Korea.
