고혈압은 증상이 없이 나타나며, 심장질환이나 뇌질환과 같이 인체에 치명적인 손상을 입히기 때문에 '조용한 살인자(silent killer)'라고 불린다. 고혈압을 예방하기 위해서는 체중감소, 알코올 섭취의 감소, 규칙적인 운동, 염분 섭취의 감소가 중요하다. 그리고 혈압을 강하시키기 위해서는 약물치료보다는 행동수정요법과 운동요법이 선행되어야 한다고 하였다. 고혈압을 치료하기 위해서 속보나 조깅, 자전거, 수영과 같은 산소운동이 가장 좋다고 보고되고 있다. 그러나 화자들은 저마다의 생리적 특성이 다르다. 관절이 좋지 않은 사람, 허리에 통증이 있는 사람, 운동 중 혈압의 반응이 비정상적인 사람 등 다양하다. 본고에서는 고혈압 환자에게 권장되는 운동종목을 제시하고, 운동종목별 특성과 주의사항을 제시하고자 한다.

한의학에 있어서 음양의 조절은 매우 중요하다. 숙지황은 음허를 치료하는 주약이며, 부자는 양허를 치료하는 주약이다. 한의학에서 신성고혈압의 발생은 음허와 관련이 있다고 하였다. 본 연구는 실험적 신성고혈압과 자연발증고혈압 백서에 숙지황과 부자 전탕액을 투여 후 혈압의 변동과 혈장 renin 활성도, aldosterone 및 심방이뇨호르몬 (atrial natriuretic hormone)의 변동을 관찰하였다. 숙지황 투여후 실험적 신성고혈압 백서의 혈압은 감소하였다. 부자 전탕액 투여 후 자연발증고혈압 백서의 혈압 상승이 억제되었다. 숙지황 및 부자 전탕액 투여 후 자연발증고혈압 백서의 혈장 renin 활성도는 감소하였다. 부자 전탕액 투여 후 신성고혈압 백서의 혈장 ANP 농도는 감소하였다. 부자 전탕액의 혈압강하 작용은 ANP 및 aldosterone 농도의 변동과 관련이 있다고 사료된다.

본 연구에서는 생체 뇌 국소부위의 세포외액을 대상으로 실험할 수 있는 뇌 미세투석법을 이용하여 후시상하부에서 유리되는 monoamine의 세포외액 농도에 대한 전신 혈압변화의 영향을 관찰함으로써, 심혈관 조절에 대한 후시상하부의 monoamine성 뉴론의 생리적 역할을 규명하고자 하였다. 마취한 흰쥐의 머리를 뇌정위 고정장치에 고정시키고 미세투석관 (microdialysis probe)을 후시상하부에 위치시킨 후 링거액으로 관류하였다. 미세투석액내에 존재하는 monoamine성 신경 전달물질들과 그 대사체들의 정량분석은 고속액체크로마토그라피와 전기화학검출기를 이용하여 실시하였다. 전신 혈압을 40분 동안 약 40mmHg 상승 혹은 30mmHg 감소시키기 위하여 L-phenylephrine hydrochloride (800ng/100 g/min) 혹은 nitroprusside dihydrate (500 ng/100 g/min)를 대퇴정맥을 통하여 주사하였다. 후시상하부로 부터 20분 간격으로 얻은 투석액에서 신정화학물질들의 농도는 미세투석관 삽입후 2시간에 안정되었다. 관류액의 $K^{＋}$ 농도를 90 mM로 증가시켰을 때 후시상하부의 투석액에서 norepinephrine (NE) 과 serotonin (5-HT)의 농도는 각각 기준치의 176.5 $\pm$ 14.8%, 149.1 $\pm$ 2.3%로 증가하였다. Phenylephrine (i.v.)으로 유발된 전신 혈압상승에 의하여 NE과 5-HT의 양은 각각 기준치의 79.3 $\pm$ 4.4%, 61.4 $\pm$ 10.3%로 유의하게 감소하였다. 또한 nitroprusside (i.v.)에 의하여 전신혈압이 감소하였을 때 투석액내 5-HT의 양은 기준치의 195.0 $\pm$ 23.0% 로 유의하게 증가하였다. 후시상하부의 투석액내 monoamine성 대사체들의 경우에는 전신 혈압의 변화에 대한 유의한 반응을 나타내지 않았다. 이상을 종합하면 전신 혈압이 증가되었을 때는 말초 압수용체의 흥분에서 기시한 신경충동이 후시상하부에 전달되어 신경말단에서 5-HT 과 NE 의 유리가 감소되고, 5-HT의 경우에는 전신 혈압이 감소되었을때 그 반대 현상이 일어난다는 가설을 제시할 수 있다. 본 연구의 결과는 생체상태에서 혈압변화에 대한 후시상하부의 monoamine성 조절양상을 규명한 것으로서 특히 후시상하부의 serotonin성 신경계를 통한 심혈관 중추조절의 가능성을 처음으로 제시한 것이다.

The purpose of this study was to investigate the changes of blood pressure and total cholesterol after eating Hizikia fusiforme for 8 weeks with 100g of rice per day. As a result, the systolic blood pressure of the group ingesting Hizikia fusiforme significantly decreased. Second, diastolic blood pressure decreased significantly in both groups, but there was no difference between groups. Third, the systolic - diastolic blood pressure difference showed a significant decrease in the group of ingestion of Hizikia fusiforme, while that of the group without intake of Hizikia fusiforme increased. Fourth, total cholesterol decreased significantly in the group consuming Hizikia fusiforme but increased in the group not consuming Hizikia fusiforme. The above results indicate that total intake of 100 g of dried Hizikia fusiforme per day was effective in decreasing total cholesterol and reducing systolic blood pressure.

Objectives: Previous studies have shown that periodic limb movements in sleep (PLMS) could be one of risk factors for cardiovascular morbidity. The purpose of this study was to investigate the association between PLMS and blood pressure changes during sleep. Methods: We analyzed data from 358 adults (176 men and 182 women) aged 18 years and older who were free from sleep apnea syndrome (Respiratory Disturbance Index < 5) and sleep disorders such as REM sleep behavior disorder or narcolepsy. Demographic characteristics, polysomnography records, and clinical variable data including blood pressure, body mass index, alcohol, smoking, and current medications were collected. In addition, self-report questionnaires including the Beck Depression Index, Epworth Sleepiness Scale and Pittsburgh Sleep Quality Index were completed. Blood pressure change from bedtime to awakening was compared between the two periodic limb movement index (PLMI) groups [low PLMI ($PLMI{\leq}15$) and high PLMI (PLMI > 15)]. Blood pressure change patterns were compared using repeated measures analysis of variance. Results: Systolic blood pressure in the high PLMI group was lower than that in the low PLMI group (p = 0.036). These results were also significant when adjusted for gender and age, but were not statistically significant when adjusted for BMI, alcohol, smoking, anti-hypertension medication use and sleep efficiency (p = 0.098). Systolic blood pressure dropped by 9.7 mm Hg in the low PLMI group, and systolic blood pressure in the high PLMI group dropped by 2.9 mm Hg. There was a significant difference in delta systolic blood pressure after sleep between the two groups in women when adjusted for age, BMI, alcohol, smoking, antihypertensive medication use and sleep efficiency (p = 0.023). Conclusion: PLMS was significantly associated with a decreasing pattern in nocturnal BP during sleep, and this association remained significant in women when adjusted for age, BMI, alcohol, smoking, antihypertension medication use and sleep efficiency related to blood pressure. We suggest that PLMS may be associated with cardiovascular morbidity.

In diabetes mellitus, renal disease is a common complication, characterized by increased urinary albumin excretion and reduced eGFR. According to KDIGO CKD stage classification, Korean characteristics were analyzed according to urinary albumin and eGFR using the National Health and Nutrition Examination Survey VI raw data. According to KDIGO classification, diabetic patients were classified as Low risk 72.0%, Moderate risk 19.3%, High risk 5.6% and Very high risk 3.0%. Low risk decreased from 74.7% to 52.2%, and moderate to very high risk increased from 25.4% to 47.8% as the duration of diabetes mellitus was prolonged. The risk factors were CKD stage 1 (HR 2.064) to stage 4 (HR 11.049), the highest risk of hypertension. The incidence of renal disease was elevated according to duration of hypertension and HR 0.42 of kidney disease was decreased in the group maintaining proper blood pressure. In the hypertensive patients, the group administered with target blood pressure had a reduction of the kidney disease by 42% than the group with the hypertension. Therefore, controlling and managing hypertension to target blood pressure is important for the prevention of kidney disease.

Eritadenine (EA), derived from Lentinus edodes (LE), reduced low-density lipoprotein (LDL), triglyceride (TG), and phospholipids in bloods, and fatty acid depositions in animals and humans. Previously, we reported that EA inhibited angiotensin-converting enzyme (ACE) activity in vitro. Now, we report that EA reduced blood pressures in spontaneous hypertension rats (SHR). EA-containing LE mycelial culture enzyme extract (EA-LEMSCEE) was prepared from LE mycelial solid cultures and the hot-water extract of LE fruit bodies. Both EA and EA-LEMSCEE inhibited ACE activity in immortalized human umbilical endothelial cells (EA.hy926). EA-LEMSCEE treatments (7.5 mg/kg, 22.5 mg/kg) significantly reduced systolic and diastolic blood pressure in SHR. At five weeks of treatment, EA-LEMSCEE treatment significantly reduced systolic and diastolic blood pressure, similar to the positive control (captopril, CP; 4 mg/kg) treatment. In addition, the LEMSCEE without EA decreased systolic and diastolic blood pressures compared to the control, but not significant. EA-LEMSCEE decreased renin and ACE activities, and angiotensin II (Ang II) contents in SHR compared to the control. After five weeks of treatment, the effect of EA-LEMCEE was similar to that of CP. These results indicate that EA and EA-LEMSCEE reduce blood pressure by inhibiting the renin and ACE activity of SHR. Furthermore, these results imply that EA or EA-LEMSCEE could be used as an antihypertension agent in humans.

It is well known non-drug therapy for hypertension patients can reduce blood pressure. These types of therapy include maintaining ones ideal body weight, quitting smoking, consuming large amounts of fruits and vegetables consuming low levels of saturated fat and salt and regular exercise. Fermented milk protein derived biologically active peptides such as isoleucine-proline-proline_(IPP) or valine-proline-proline_(VPP) have been shown to lower blood pressure in hypertensive subjects. This study was conducted to investigate the antihypertensive effects of medical nutritional therapy _(MNT) in accordance with the consumption of fermented milk enriched with IPP and VPP. To accomplish this, we conducted a randomized case-controlled study of 43 subjects who had blood pressure levels greater than 120/80 mmHg. The subjects in the study group were randomly allocated into two groups, an MNT + fermented milk (100mL/day) group (n=21) and an MNT+L. helveticus fermented milk with tripeptides (IPP=2.2mg, VPP=2.6mg/100mL) group (n=22). The MNT included weight management, reduction of sodium, total fat and saturated fat intake, increased intake of fruits and vegetables, and increased intake of low fat dairy products. The treatments were administered for 12 weeks during which time no drug interventions were conducted. The daily intakes of total calories, fats, cholesterol and Na decreased significantly after 12 weeks of MNT in the control and the experimental groups. In addition, the systolic blood pressure de creased significantly in the control and experimental groups; however, the diastolic blood pressure only decreased significantly in the experimental group. Overall, the results of this study indicate that the intake of fermented milk containing IPP and VPP in conjunction with MNT exerted positive effects on the blood pressure of pre- and hypertensive subjects.
