The purpose of this study was to evaluate the effect of health services on workers with hypertension in small and medium sized enterprises (20-300 employees). One hundred seventy three workers among 296 workers with hypertension were responded to the questionnaire on general and occupational characteristics, health habits and anti-hypertensive medications. Blood pressure was obtained while seated using a calibrated standard manometer before and after 4 months health services. Statistical analysis was performed using $X^2$-test and logistic regression analysis. The results were as follows ; 1. No significant differences were noted in variables of smoking, glucose intake and sleeping time, while significant differences were showed in variables of exercise time, frequency and amount of drinking and intake of salt, protain, lipid, calcium, vegetable and fruits between groups which was provided and not provided health services. 2. The rate of anti-hypertensive medication was increased and the blood pressure was decreased significantly in group which was provided health services compared with those of group which was not provided. 3. With the logistic regression analysis, significant variables affecting blood pressure change were smoking and anti-hypertensive medication. The results of this study suggested that health services on workers with hypertension in small and medium sized enterprises was effective, and the role of health professionals for health promotion movement in enterprises was important.

Objectives : The aim of this study was to investigate the correlation between Cold-Heat pattern tendency and demographic traits, physical character, and vital signs in hypertensive patients taking anti-hypertensive agents. Methods : 28 hypertensive patients 30 to 69 years old were recruited. We assessed their general characteristics, physical characteristics (height, weight, waist circumference, etc.), vital signs without respiratory rate (blood pressure, pulse rate, temperature) and administered a Cold-Heat pattern questionnaire. After that, we analyzed statistical data on separate groups according to Cold-Heat characteristics or other criteria. Results : 1. Heat group patients had statistically higher scores in waist, body mass index (BMI), waist circumference and pulse rate. 2. Over weighted group patients had statistically lower scores in cold Pattern Identification. 3. Higher BMI group (above 23/25) patients had statistically significantly higher Heat scores and lower Cold scores, higher waist circumference group patients had lower Cold scores. Conclusions : From the above result in hypertensive patients taking hypertensive agents, Heat group had a obesity tendency and the inverse is also valid. Later, progressed study based on more samples and varied data will contribute to diagnosis the Cold-heat Pattern identification in hypertensive patients.

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.

The aim of this study was to investigate a potential effect of treatment of spontaneously hypertensive rats (SHR) with Pini Folium or Leonuri Herba extracts. Male SHR were treated with extracts for 2 or 4 weeks starting at 13 weeks of age. We found that oral treatment with the methanol extract from Pini Folium or Leonuri Herba (1g/Kg/day) significantly decreased mean blood pressure to 85.4% and 78.6% respectively in compare with untreated control SHR. Treatment with the extract from Pini Folium for 4 weeks during hypertension development phase (starting 9 weeks of age) resulted in a partial prevention of hypertension development. There were no significant differences for body weight between untreated and Pini Folium treated SHR.

The present study investigated whether electroacupuncture (EA) can alleviate hypertension and concomitant disorders such as decreased kidney weight and elevation of serum creatinine in spontaneous hypertensive rats. EA (2 Hz, 3 mA, 10 min) was applied to Joksamni (ST36) once daily for 7 days. Body weight, blood pressure and heart rate were measured on Day 0, 2, 6, 8, 10 and 12, and kidney weight and serum creatinine levels were examined after sacrifice (on Day 12 after last examination). In the ST36 group, the blood pressure were significantly decreased from 6thdays and its effects lasted up to Day12 (up to 5days after cessation of acupuncture), compared to control. And, significant decreases of the heart rates after EA at ST36 were also observed on Day 2, 6, and 8. However, there were no significant differences in daily body weight, kidney weight and serum creatinine between acupuncture and control group. These results showed that EA at ST36 caused anti-hypertension by decreasing blood pressure and heart rates in spontaneous hypertenstive rats, although it failed to alleviate concomitant disorders such as the decreased kidney weight and elevation of serum creatinine shown in hypertensive rats.

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.

Because nonsteroidal anti-inflammatory drugs are reported to cause fluid retention and hypertension by inhibition of prostaglandin synthesis, the effects of piroxicam on pharmacodynamics and pharmacokinetics of nifedipine were studied in male spontaneously hypertensive rats. They received nifedipine (0.5 mg/kg) alone or combined with piroxicam (5 mg/kg) intravenously. Plasma levels norepinephrine, an index of sympathetic stimulation, were measured prior to each treatment and 5 min after drug administration. Changes in blood pressure were examined serially and blood samples for analysis of nifedipine were also taken for 6 hr following drug administration. Plasma nifedipine concentration were assayed by HPLC and pharmacokinetic parameters were calculated. Blood pressure was reduced (p<0.01), but plasma norepinephrine level was increased (p<0.05) by nifedipine administration. Anti-hypertensive effect of nifedipine was potentiated (p<0.05) by piroxicam coadministration, but effect of nifedipine on plasma norepinephrine level was not affected. In case of rats received nifedipine and piroxicam, plasma nifedipine concentrations were higher (p<0.05) than those from rats received nifedipine alone at 2,3,4,5 and 6 hours following drug administration. The area under the plasma concentration vs. time curve was increased (p<0.05), while the elimination rate constant was decreased (p<0.01) by piroxicam coadministration. No significant differences were observed in the plasma clearance, apparent volume of distribution and elimination half-life. Thus, piroxicam not only potentiated antihypertensive effect of nifedipine, but also altered nifedipine pharmacokinetics in the rats. It is concluded that the potentiation of nifedipine antihypertensive effect might correlate with the increment of its plasma concentration by piroxicam coadministration.

In spite of the fact that a variety of unfailing guidelines are existing for the management of hypertension, the problem of inadequate managing of this condition still continues. Several classes of existing antihypertensive drugs are associated with various side-effects. Since ancient times before the advent of anti-hypertensive drugs, this disease has been treated by the prominent classical scholars. Various herbal drugs are being used since ages for the treatment of hypertension and some of them are validated too. Evolvulus alsinoides is also one such herb used in classical literature since ages for various disorders like insanity, anxiety, nervous debility, epilepsy, melancholy, palpitation and many others. This review is to highlight the antihypertensive potential of Evolvulus alsinoides.

It has been suggested that hyperuricemia is related to the development of essential hypertension. Hypertensive patients with hyperuricemia has decreased glomerular filtration activity as compared to normotensive patients with hyperuricemia. These studies indicates uric acid concentrations in blood is associated with hypertension, Probenecid is an uricosuric agent which decreases uric acid reabsorption at the proximal tubule. Recently, we have shown that probenecid exerts anti-hypertensive action in Spontaneously Hypertensive Rats. Considering these results, I have designed a series of experiments to explore potential mechanism of antihypertensive action, of probenecid. In isolated rat thoracic aorta. probenecid significantly prevented phenylephrine-induced contraction of the blood vessel. When endothelium removed blood vessels were used, probenecid produced same effect as the intact blood vessels, indicating that probenecid directly act through the ${\alpha}$ -adrenergic receptor in vascular smooth muscles rather than through endothelium. These results suggest that one of the mechanism of antihypertensive effects of probenecid is due to the direct inhibition of ${\alpha}$ -adrenergic receptor in blood vessels.
