  • In cardiovascular disease the flow adaptation of erythrocytes can be affected by reduced shear stresses and metabolic influences on red cell fluidity as a consequence of tissue hypoxia. In addition there are indications that risk factors of cardiovascular diseases are able to decrease the intrinsic red cell deformability. Erythrocyte deformability was studied by the filtration technique of Reid et al. to investigate the relationship between blood pressure chances and erythrocyte deformability. In this experiment normotensive rats, spontaneously and DOCA-salt treated hypertensive rats were used. Erythrocyte deformability was significantly reduced by blood pressure elevation in hypertensive rats but was not fully recovered by normalization of blood pressure after antihypertensive drug treatment. Therefore other factors than blood pressure may be involved in erythrocyte deformability reduction during blood pressure elevation.

  • RBC (red blood cell) deformability is one of factors inducing blood shear thinning effect. Reduction of RBC deformability increases blood viscosity in high shear region. In this study, 3D printed chip with proper distribution of wall shear rate (WSR) was proposed to measure RBC deformability of blood samples. To fabricate 3D printed chip, the design of 3D printed chip determined through numerical simulation was modified based on the resolution of the 3D printer. For the estimation of pressure drop in the 3D printed chip, two bypass outlets with low and high WSR are exposed to atmospheric pressure through the needles. By positioning the outlet of needles in the gravity direction, the formation of droplets at bypass outlets can be captured by smartphone. Through image processing and fast Fourier transform (FFT) analysis, the frequency of droplet formation was analyzed. Since the frequency of droplet formation is related with the pressure at bypass, high pressure drop caused by reduction of RBC deformability can be estimated by monitoring the formation of blood droplets using the smartphone.

  • Objectives : The aim of this study was to investigate the antihypertensive effect of S'NC nerve control treatment in hypertensive patients. Methods: We measured the blood pressure of 5 patients who were admitted in the Oriental Medical Clinic of S'NC Medicine Research Institute from 19th April 2007 to 29th June 2007. Eligible participants had systolic blood pressure ${\ge}$140mmHg or diastolic blood pressure ${\ge}$90mmHg. Blood pressure measurements were after the patient had been in bed rest for at least 10 min. Ten sessions of S'NC nerve control treatment over 2 weeks were performed in the patients. Blood pressure were measured twice before and after each treatment. Results : After 2 weeks, blood pressure reduction was observed in the treatment patients, with an average decline of systolic blood pressure up to 21mmHg and diastolic blood pressure up to 20mmHg. But, there were not statiscally significant The effects of S'NC nerve control treatment by measuring time on blood pressure were as follows: In a systolic blood pressure(p=0.087) and diastolic blood pressure(p=0.609) was gradually deceased not significantly from 1st to 10th. Conclusion: These results suggest that S'NC nerve control treatment may be efficacious in decreasing arterial blood pressure in hypertensive patients. Controlled trials investigating the efficacy of S'NC nerve control treatment for lowering blood pressure are warranted.

  • In 30 rats divided into salt, ethanol and salt plus ethanol groups, the effect of ethanol on the course of hypertension induction with the salt ingestion was studied. The results obtained from the present study are as follows. 1) In salt group mean arterial blood pressure elevated to plateau (about 140 mmHg) in two weeks and the increased blood pressure was well maintained throughout entire experimental period. 2) By four weeks after ethanol ingestion, mean arterial blood pressure of ethanol group was slightly decreased followed thereafter by slow restoration to control value. And it was believed that decline of blood pressure observed in this case probably was not resulted from cardiac depression. 3) As mean arterial pressure in salt plus ethanol group remained rather low compared with that of salt group, it was suggested that ethanol may have a dose reduction effect in the course of hypertension induction by excessive salt ingestion. It was, however, not possible from the result of present study to decide that low blood Pressure in this group was resulted whether from enhanced sodium excretion activity of ethanol or from effect on blood pressure of ethanol itself.

  • Objectives : The purpose of the study was to determine the effects of a 4 weeks Meridian Tai Ji exercise treatment on blood pressure reducing in hypertensive patients. Methods : We measured the blood pressure of 3 patients who were visited in the Gwacheon Health center from 21th November 2007 to 17th December 2007. Eligible participants had systolic blood pressure ${\geq}$ 120 mmHg or diastolic blood pressure ${\geq}$ 80 mmHg with antihypertensive drug. Blood pressure measurements were after the patient had been in rest for at least 10 minute. Twelve sessions of Meridian Tai Ji exercise treatment over 4 weeks were performed in the patients. Blood pressure were measured twice before and after each session. Results : After 4 weeks, blood pressure reduction was observed in the treatment patients, with an average decline of systolic blood pressure up to 5.67 mmHg and diastolic blood pressure up to 0.17 mmHg. But, it was not statistically significant. Blood pressure increased between measurements taken before and after an Meridian Tai Ji exercise treatment session, although individual responses were quite variable. No significant difference was found in the immediate effect. Conclusion : Twelve sessions of Meridian Tai Ji exercise treatment do not seem to control hypertension. Further research is required to determine whether Meridian Tai Ji exercise treatment can enhance clinical management of hypertension if it is used in combination with more enrolled participants, over longer periods, or randomized controlled trial.

  • Purpose: This study is to evaluate the effect of abdominal breathing on postoperative pain, state anxiety, blood pressure, and heart rate of cardiac surgery patients treated in intensive care unit. Methods: A non-synchronized design of nonequivalent control group pre-post test was used. Participants were divided into an experimental group(n=22) and a control group(n=21). Just usual postoperative treatments were provided to the control group, while abdominal breathing interventions were provided to the experimental group, in addition to usual treatments. The intervention was consisted of 4 stages-introductions, breathing perception, breathing training, and closing-and it lasted twelve minutes in total. Pain, state anxiety, blood pressure and heart rate were the dependent variables of the abdominal breathing. Results: Those who carried out abdominal breathing showed a significant reduction in pain, as well as decrease of systolic blood pressure. However, it turned out to have no effect on state anxiety, diastolic blood pressure and heart rate. Conclusion: Abdominal breathing is simple and harmless and is effective for reducing postoperative pain.
