Objectives The purpose of this study was to reveal that Sasang constitution(SC) was associated with hypertension and pre-hypertension and could be a risk factor. Methods We introduced this study to educational personnel in D university in Daejeon, and 275 subjects joined this study. The SC classification was conducted with KS 15 questionnaire. The subjected measured the blood pressure with Jawon medical device automatically after 10 minute rest. The hypertension and pre-hypertension was classified by the guide of the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure. The frequency analysis and T-test was used in general characteristics, and chi-square test was also used between SC and pre-hypertension and hypertension. Logistic regression was used to calculate the odds ratios (ORs) and 95% confidence interval (95% CI) for pre-hypertension and hypertension. Results The number of Taeeumin(TE), Soeumin(SE), and Soyangin(SY) was 142, 71, and 61 respectively. There was significantly different in systolic and diastolic blood pressure among SC types(p<.001). The distribution of the normal group, pre-hypertension and hypertension group by SC types was significantly different (p<.001). The ORs of TE was significantly increased (ORs 4.039, 95% CI=2.019-8.082 in pre-hypertension and ORs 4.235, 95% CI=1.581-11.348 in hypertension) compared with SE(p<.001), and after adjusting gender and smoking habit, it was still significantly different(p<.001). Conclusions It is possible that SC, especially TE could be a risk factor both pre-hypertension and hypertension.

Background: Postural hypotension refers to a drop in systolic blood pressure of 20 mmHg or diastolic blood pressure of 10 mmHg or more within three minutes after standing up from lying down. Symptoms of postural hypotension not only include dizziness and blurred vision but also fatigue, cognitive decline, leg weakness, headache, and, in severe cases, fainting. Postural hypotension is a phenomenon that occurs in about 6% of the total population, and in Korea, the number of patients with postural hypotension is continuously increasing. Both pharmacological and non-drug therapies, which are treatment methods for this disease, do not show a satisfactory symptom improvement effect. Case summary: A 65-year-old male patient who visited the hospital complaining of dizziness and paresthesia due to postural hypotension was treated with acupuncture, moxibustion, and herbal medicine. For symptom evaluation, the numeric rating scale (NRS) of each symptom was used, and blood pressure change according to posture was measured. After treatment, the NRSs of dizziness and dysesthesia were decreased, and blood pressure changes according to posture was improved. Conclusion: This case report suggests that Korean medicine treatment, including acupuncture, electro-acupuncture, moxibustion, and herbal medicine, can be an effective treatment for dizziness with postural hypotension.

Purpose : Sarcopenic obesity is associated with adverse health consequences in females. Nevertheless, there has been limited research on the hazardous components and prevailing rates of sarcopenic obesity among younger women. This study aimed to identify the hazardous components and prevailing rates of sarcopenic obesity in younger females. Methods : This study utilized data based on 2008~2011 from the Korea National Health and Nutrition Examination Surveys by the centers for disease control and prevention. The analysis was concentrated on a subset of 1,520 women aged between 30 and 39 years of age. The participants answered a questionnaire to gather demographic information. They then underwent a physical examination to measure the human detention variables, which was conducted utilizing bioelectrical impedance analysis. The blood pressure and blood laboratory tests were determined using established laboratory protocols for evaluating blood parameters. Results : This study included 1,520 patients aged 30~39 years old. The mean age of the participants was 34.97 (years)±2.74 and the overall prevailing rate was 1.84 %. The hazard components in human dimensions were the height, weight, body mass index (BMI), waist circumference (WC) and skeletal muscle mass index (SMI). The hazard components in biochemical and blood pressure were high fasting glucose, increased triglyceride, elevated total cholesterol, high systolic blood pressure, and increased diastolic blood pressure with p-values <.05. Conclusion : This study examined the hazardous components and prevailing rates of sarcopenic obesity in younger women living in the community. The results contribute to the current body of knowledge on sarcopenic obesity and shed light on possible hazardous components in a younger female population. Based on these findings, there should be increased health and medical attention towards the prevention, management, and health promotion related to reducing risk factors for sarcopenic obesity in younger women.

Background and Objectives: Self-monitoring of blood pressure (SMBP) is a reliable method used to assess BP accurately. However, patients do not often know how to respond to the measured BP value. We developed a mobile application-based feed-back algorithm (SMBP-App) for tailored recommendations. In this study, we aim to evaluate whether SMBP-App is superior to SMBP alone in terms of BP reduction and drug adherence improvement in patients with hypertension. Methods: Self-Monitoring of blood pressure and Feed-back using APP in Treatment of UnconTrolled Hypertension (SMART-BP) is a prospective, randomized, open-label, multicenter trial to evaluate the efficacy of SMBP-App compared with SMBP alone. Patients with uncomplicated essential hypertension will be randomly assigned to the SMBP-App (90 patients) and SMBP alone (90 patients) groups. In the SMBP group, the patients will perform home BP measurement and receive the standard care, whereas in the SMBP-App group, the patients will receive additional recommendations from the application in response to the obtained BP value. Follow-up visits will be scheduled at 12 and 24 weeks after randomization. The primary endpoint of the study is the mean home systolic BP. The secondary endpoints include the drug adherence, the home diastolic BP, home and office BP. Conclusions: SMART-BP is a prospective, randomized, open-label, multicenter trial to evaluate the efficacy of SMBP-App. If we can confirm its efficacy, SMBP-App may be scaled-up to improve the treatment of hypertension.

This study was carried out to investigate the effect of Gastrodiae Rhizoma (G. Rhizoma) on blood pressure-lowering in spontaneously hypertensive rats (SHR) fed high-fat diet supplemented with 10% (w/w) of lard during the experimental period of 8 weeks. Forty of male SHR weighing approximately 100 g were randomly divided into eight groups; A: negative control (lard 10%), B: positive control (lard 10% ＋ basal diet ＋ 5 brix water extract), C: lard 10% ＋ 1% G. Rhizoma powder, D: lard 10%＋5% G. Rhizoma powder, E: lard 10%＋2 brix 50% ethanol extract, F: lard 10%＋10 brix 50% ethanol extract, G: lard 10%＋2 brix water extract, H: lard 10% ＋ 10 brix water extract. A gain in weight did not differ significantly among dietary groups, but a little higher in control groups than in G. Rhizoma dietary groups. Except for spleen, weights of liver, kidney and testis are significantly different among dietary groups. Serum total cholesterol concentration was markedly higher in control groups than in G. Rhizoma groups (p<0.05), however, there was no significant difference in serum triglyceride. Except for negative control (A) and group D, serum HDL concentration was significantly higher in G. Rhizoma groups (p<0.05). On the other hand, serum LDL concentration was significantly higher in two control groups (A, B) and markedly lower in E and G groups of hot water extract of G. Rhizoma (p<0.05). Reference systolic blood pressure (BP) showed average 185.7$\pm$5.8 mmHg for 4 weeks after feeding high-fat diet, and the pressure was measured on every 7 days intervals after feeding of G. Rhizoma diet. Comparing with reference BP before feeding of G. Rhizoma diet, the groups of 50% ethanol (E, F) and water (G) extracts on BP level after 28 days were shown to be reduced at 16.8, 20.2 and 11.7 mmHg, respectively. When the pressure (187 mmHg) of group A was considered as 100%, the reduction rate of BP in group F was 11% (20.5 mmHg). These results indicated that the groups treated with ethanol extracts of G. Rhizoma showed to have lower blood pressure level compacred to the groups treated with whole powder or water extracts of G.Rhizoma in SHR fed with high-fat diet.

When the systolic blood pressure is high, intermittent turbulence in blood flow appears in the aorta and carotid artery with stenosis during the systolic period. The turbulent blood flow is difficult to analyze using the Newtonian turbulence model due to the viscous characteristics of blood flow. As the shear rate is increased, the blood viscosity decreases by the viscoelastic properties of blood and a drag reduction phenomenon occurs in turbulent blood flow. Therefore, a new non-Newtonian turbulent model is required for viscoelastic fluid and hemodynamics. The main aims of this study were to develop a non-Newtonian turbulence model using the drag reduction phenomenon based on the standard $k-{\varepsilon}$ turbulent model for a general non-Newtonian fluid. This was validated with the experimental data and has a good tendency for non-Newtonian turbulent flow. In addition, the computation time and resources were lower than those of the low Reynolds number turbulent model. A modified turbulent model was used to analyze various turbulent blood flows.

To attain a simple and reliable method of evaluating the thyroid function the reliability of the clinical manifestation and the conventional thyroid function tests in diagnosing the hyperthyroidism was studied. The subjects included 184 patients with hyperthyroidism and 66 cases with euthyroidism, who were treated at the Thyroid Clinic, Seoul National University Hospital, from July 1971 through August 1972. The observed results were as follows: 1. In the cases of hyperthyroidism, 19% of the patients were male and 81% female; in the cases of euthyroidism, 7.6% of the patients were male and 92.4% female. The majority of the patients were in 2nd to 4th decades of their lives. 2. There were objective signs clearly manifested in hyperthyroidism which were rare or absent in the euthyroid state. These clinical signs included wide pulse pressure, tachycardia, systolic murmur, exophthalmos, tremor, and warm skin. In the hyperthyroid state 91.3% of the cases manifested two or more of the above signs, whereas in the euthyroid state no patients manifested any two of the above signs. 3. The most frequent complaints of the patients with thyroid disease were palpitation, weight loss, increased appetite, heat intolerance, perspiration, hunger feeling; nervousness, exertional dyspnea, etc. There was no clear difference in the incidence of the symptoms between hyperthyroidism and euthyroidism. 4. In the diagnosis of hyperthyroidism, the reliability of thyroid ?unction tests was as follows; $T_7$ was 92.4% reliable, $^{125}IT_3$ resin uptake rate 91.6% reliable, $^{131}I$ thyroid uptake rate in 24 hrs. 89.4% reliable, serum $T_4$ level 85.9% reliable and BMR 75.5% reliable. Therefore the careful observation of the clinical manifestation of the disease is a simple and reliable way of making a correct diagnosis of either hyperthyroidism or euthyroidism. 5. In hyperthyroidism there shows no correlationship between the results of the thyroid function test and clinical signs but a high BMR was associated with both tachycardia and systolic murmur.

Residual significant tricuspid regurgitation after mitral valve operation may significantly increase postoperative morbidity and mortality. However, routine techniques to detect tricuspid regurgitation preoperatively and postoperatively are not accurate. Doppler echocardiography was performed preoperatively and postoperatively to assess its ability to evaluate and quantify the severity of tricuspid regurgitation. In 34 patients with tricuspid regurgitation secondary to mitral valvular disease the tricuspid regurgitations were semiquantified on a scale of 1 to 3+. The 34 patients were divided into two groups on the basis of severity of tricuspid regurgitation as assessed by preoperative Doppler echocardiography. Group I [8 patients] had mild[1+] regurgitation, and group II [26 patients] had moderate to severe[2 ~ 3%] tricuspid regurgitation. In all studied patients, preoperative Doppler echocardiographic studies for the degree of tricuspid regurgitation were correlated with clinical symptoms[including NYHA class] and hemodynamics[JVP and right ventricular systolic pressure], and used as the indicator to determine whether tricuspid annuloplasty should be performed or not. Patients with significant tricuspid regurgitation[group II ] had greater preoperative right ventricular systolic pressures and NYHA classes, although there was no correlation between them. The 8 patients with mild[1+] tricuspid regurgitation[group I ] didn`t undergo any procedure for the tricuspid regurgitation and their postoperative Doppler echocardiographic studies showed the less than mild[0 ~ 1+] tricuspid regurgitation, and the 26 patients with significant[>2+] tricuspid regurgitation, and the 26 patients with significant[>2+] tricuspid regurgitation[group II ] underwent tricuspid annuloplasty for the tricuspid regurgitation and the postoperative Doppler echocardiographic studies showed the findings similar to group I except 1 patient who underwent Carpentier`s ring annuloplasty and had severe right ventricular failure. Therefore, preoperative Doppler echocardiography can accurately assess the relative severity of tricuspid regurgitation. Importantly, postoperative Doppler echocardiography could conveniently determine the effect of tricuspid annuloplasty for the patients with significant tricuspid regurgitation. Doppler echocardiography may be an important diagnostic method both for evaluating the degree of residual tricuspid regurgitation after left heart operation as well as for determining which patients should undergo tricuspid valve repair.
