Purpose: The purpose of this study was to examine self care behaviors according to the risk levels of vascular complications in elderly women with hypertension. Methods: The subjects of this study were 162 women living in the community who had been diagnosed with hypertension in clinics. The data were analysed by the SPSS 10.0 program using descriptive statistics, t-test, and ANOVA with Scheff$\dot{e}$ post-hoc test. Results: The average self care behavior score of the elderly women was 2.79. Total self care behavior was significantly different depending on the risk levels of vascular complications such as systolic blood pressure, diastolic blood pressure, ankle-brachial index, and the framingham point score. Among sub-scores of self care behaviors, exercise management was the poorest performance compared with other self care behaviors. Conclusion: This study proved the differences in self care behaviors according to the risk levels of vascular complications. To decrease the prevalence of vascular complication, it is necessary to develop programs specifically to enhance self care behaviors of elderly women with hypertension.

The evaluation of the effectivess of ongoing cardiopulmonary resucitation efforts is dependent on the commonly used methods, such as the presence of femoral or carotid artery pulsations, arterial blood gas determinations, peripheral arterial pressure and intracardiac pressure monitoring. But recent studies suggest that end-tidal carbon dioxide tension serves as a non-invasive measurement of pulmonary blood flow and therefore cardiac output under constant ventilation. A prospective clinical study was done to determine whether end-tidal carbon dioxide monitoring in open heart surgery under cardiopulmonary bypass could be used as a prognostic indicator of bypass weaning. We monitored end-tidal PCO2 values continuously during cardiopulmonary bypass in 30 patients. "Ohmeda 5210 CO-2 monitor" under infrared absorption method were incorperated into the ventilator circuit by means of a side point adaptor between endotracheal tube and ventilator tubing. 18 patients[Group I ] were res-ucitated from partial bypass followed by aorta cross clamp off and 12 patients[Group II ] from aorta cross clamp off followed by partial bypass. But there was no difference between two groups[p>0.05]. The value of end-tidal carbon dioxide tension during ventricular fibrillation or nearly arrest state was 6.6$\pm$2.9 mmHg, and at the time of spontaneous beating was 19.3$\pm$5.6 mmHg[Mean$\pm$Standard deviation], In conclusion end-tidal carbon dioxide tension monitoring provides clinically useful, continous, noninvasive and supplementary prognostic indicator during cardiopulmonary bypass weaning procedures.rocedures.

Purpose: This study was done to identify pain perception (P-PER) by nurses and pain expression (P-EXP) by patients in critical care units (ICUs) and degree of agreement between nurses' P-PER and patients' P-EXP. Methods: Nurses' P-PER was measured with a self-administered questionnaire completed by 99 nurses working in ICUs during May, 2013. Patients' P-EXP was measured with the Critical Care Non-Verbal Pain Scale through observations of 31 ICU patients during nine nursing procedures (NPs) performed between May and July, 2013. Results: Nurses' P-PER was from 4.49 points for nasogastric tube (NGT) insertion to 0.83 for blood pressure (BP) measurement based on a 9-point scale, Patients' P-EXP was 4.48 points for NGT to 0.18 for BP measurement based on a 10-point scale. Eight NPs except oral care showed higher scores for nurses' P-PER than for patients' P-EXP. Position change (p=.019), subcutaneous injection (p<.001), blood sugar test (p<.001), and BP measurement (p<.001) showed significant differences between nurses' P-PER and patients' P-EXP. Conclusion: Nasogastric tube (NGT) insertion was scored highest by both nurses and patients. Eight NPs except 'oral care' showed nurses' P-PER was higher or similar to patients' P-EXP, which indicates that nurses may overestimate procedural pain experienced by patients.

Objectives: This study estimated the association of cardiovascular health behaviors with the risk of all-cause and cardiovascular disease (CVD) mortality in middle-aged men in Korea. Methods: In total, 12 538 men aged 40 to 59 years were enrolled in 1993 and followed up through 2011. Cardiovascular health metrics defined the following lifestyle behaviors proposed by the American Heart Association: smoking, physical activity, body mass index, diet habit score, total cholesterol, blood pressure, and fasting blood glucose. The cardiovascular health metrics score was calculated as a single categorical variable, by assigning 1 point to each ideal healthy behavior. A Cox proportional hazards regression model was used to estimate the hazard ratio of cardiovascular health behavior. Population attributable risks (PARs) were calculated from the significant cardiovascular health metrics. Results: There were 1054 total and 171 CVD deaths over 230 690 person-years of follow-up. The prevalence of meeting all 7 cardiovascular health metrics was 0.67%. Current smoking, elevated blood pressure, and high fasting blood glucose were significantly associated with all-cause and CVD mortality. The adjusted PARs for the 3 significant metrics combined were 35.2% (95% confidence interval [CI], 21.7 to 47.4) and 52.8% (95% CI, 22.0 to 74.0) for all-cause and CVD mortality, respectively. The adjusted hazard ratios of the groups with a 6-7 vs. 0-2 cardiovascular health metrics score were 0.42 (95% CI, 0.31 to 0.59) for all-cause mortality and 0.10 (95% CI, 0.03 to 0.29) for CVD mortality. Conclusions: Among cardiovascular health behaviors, not smoking, normal blood pressure, and recommended fasting blood glucose levels were associated with reduced risks of all-cause and CVD mortality. Meeting a greater number of cardiovascular health metrics was associated with a lower risk of all-cause and CVD mortality.

A method based on transient shear flow dynamics of red cell aggregates was developed to investigate reversible re-aggregation processes with decreasing shear flow. In the microchannel-flow aggregometry, the aggregated red blood cells that are subjected to continuously decreasing shear stress in microchannel flow were measured with the use of a laser-scattering technique. Both the laser-backscattered intensity and pressure were simultaneously measured with respect to time, resulting in shear stress ranging from $0{\sim}35\;Pa$ for a time period of less than 30 seconds. The time dependent recording of the backscattered light intensity (syllectogram) yielded an upward convex curve with a peak point, which reflected the transition threshold of aggregation in the RBC suspensions. Critical-time and critical-shear stress corresponding to the peak point were examined by varying the initial pressure-differential and the micro channel depth, and these results showed good potential for being used as new aggregation indices. In the present study, these newly proposed indices were also validated by differentiating the effect of fibrinogen on RBC aggregation and then these indices were compared to the conventional indices that were measured by a rotational aggregometer.

Objective: To investigate the effects of stellate ganglion block (SGB) on the peri-operative vasomotor cytokine content and intrapulmonary shunt in patients with esophagus cancer who underwent thoracotomy. Materials and Methods: Forty patients undergoing elective resection of esophageal cancer patients who had I~II American Society of Anesthesiologist (ASA) were randomly divided into total intravenous anesthesia group (group N, n=20) and total intravenous anesthesia combined with SGB group (group S, n=20, 0.12 mL/kg 1% lidocaine was used for SGB 10 min before induction). Heart rate (HR), mean arterial pressure (MAP), central venous pressure (CVP), mean pulmonary arterial pressure (MPAP) and continuous cardiac output (CCO) were continuously monitored. The blood from internal jugular vein was drawn respectively before induction ($T_0$), and 30 min ($T_1$), 60 min ($T_2$) and 120 min ($T_3$) after one-lung ventilation (OLV), and 30 min (T4) after two-lung ventilation. The contents of plasma endothelin (ET), nitric oxide (NO) and calcitonin gene-related peptide (CGRP) were detected with enzyme linked immunosorbent assay (ELISA). Meanwhile, arterial and mixed venous blood samples were collected for determination of blood gas and calculation of intrapulmonary shunt fraction (Qs/Qt). Results: During OLV, ET contents were increased significantly in two groups (P<0.05), and no significant difference was presented (P>0.05). NO content in group S was obviously higher than in group N at T3 (P<0.05), whereas CGRP content in group N was markedly lower than in group S at each time point (P<0.05). Qs/Qt was significantly increased in both groups after OLV, but there was no statistical significant regarding the Qs/Qt at each time point between two groups. Conclusions: Total intravenous anesthesia combined with SGB is conducive to regulation of perioperative vasomotor cytokines in thoracotomy, and has little effect on intrapulmonary shunt at the time of OLV.

The present study examined that in Vivo/Vitro test is investigated in normotensive sham-operated rats (NSR) and aldosterone-analogue deoxycorticosterone acetate (DOCA)-salt hypertensive rats (ADHR) and that the antihypertensive effect was induced by silver spike point (SSP) electrical stimulation at meridian points(CV-3, -4, Ki-12, SP-6, LR-3, BL-25, -28, -32, -52), specifically, such as aldosterone in 24 hour urine analysis from healthy volunteer. The gross examination and morphometric-histological changes, such as hypertrophy, production of necrotic tissues, and the changes of cell arrangement on the kidney, and adrenal gland were markedly observed in aldosterone-analogue DOCA-salt hypertensive rats compared with those from normotensive sham-operated rats. The systolic blood pressure, weight of kidney and adrenal gland were significantly increased in ADHR than that in NSR. The required time of PSS-induced resting tone was significantly increased in ADHR than that in NSR. However, the voltage-dependent K+ (Kv) currents were significantly decreased in ADHR than that in NSR. The urine analysis showed that the concentration of aldosterone was significantly decreased in resting state from the elderly people compared with those from the adolescent healthy volunteer. The current of 1 Hz continue type of SSP electrical stimulation significantly decreased in the concentration of aldosterone of 24 hour urine from the elderly people. These results suggest that the development of aldosterone analogue-induced hypertension is associated with changed the weight of kidney and adrenal gland, blood pressure, resting tone and Kv currents, which directly affects blood pressure. Therefore, the hypertension is a risk factor on cerebrovascular disease. Moreover, these results suggest that the diminished responsiveness to SSP electrical stimulation, especially current of 1Hz continue type, in elderly people may be, in part, related by the increased of antihypertensive effects.

Objectives : The objective of this study was to assess the effect of acupuncture applied at the ST36 point on blood pressure and endothelial dependent vasodilation in hypertensive patients. Methods : 24 hypertensive patients were recruited and randomized to a study group (12 subjects) or a control group (12 subjects). Both groups took FMD (endothelial-dependant, flow-mediated dilation) measurement and then acupuncture needles were inserted at ST36 for the study group. In the control group, they took sham acupuncture as a control. FMD was rechecked after 10-min acupuncture treatment. Blood pressure was measured before and after acupuncture treatment. Results : FMD increased significantly in the study group after acupuncture (9.5${\pm}$2.0% to 11.1${\pm}$2.2%), but not in the control group. In both groups, there were no changes in blood pressure and heart rate. Conclusions : Acupuncture on ST36 appears to improve endothelial dysfunction of hypertensive patients and this might result from inducing activation of endothelium-derived nitric oxide.
