  • Purpose: The purpose of this study is to know stress and blood stasis pattern for the patients who had hysterectomy related with uterine myoma, adenomyosis, endometriosis. Methods: We got questionnaires from 55 patients among 243 patients who had hysterectomy related with uterine myoma, adenomyosis, endometriosis in the department of obstetrics and gynecology, OO medical center from April 11th 2010 to October 14th 2010, and analyzed them. We conducted correlation analysis between age, pain(VAS), duration of pain and blood stasis score, and between duration of pain, blood stasis score and the sum of Stress Response Index. We compared the sum of Stress Response Index, blood stasis score, VAS according to the result of pathology. For statistics, we used Pearson's correlation coefficient, Mann-Whitney test, oneway analysis of variances(ANOVA) and SPSS version 17.0 for windows. Results: The correlation between duration of pain and blood stasis score showed statistical significance. The correlation between sum of the Stress Response Index and blood stasis score showed statistical significance. There is no statistically correlation between age, VAS, duration of the pain and blood stasis score. There is no statistically significant difference in sum of Stress Response Index, blood stasis score, VAS according to the result of pathology. Conclusion: The result showed that Stress is related with static blood, and the longer patients suffer from pain, the easier patients' blood to be static. Further study will be needed.

  • Purpose: The purpose of this study is to investigate the effects of relaxation on stress and blood pressure of the college students induced by a cognitive distress game. Methods: The subjects for this research were 18 individuals whose stress index scores were below 4.0 (Asan city). The 18 subjects were divided into two, 9 students were assigned to the experimental group and the other 9 students to the control group randomly. Survey was used to gather data to recognize general characteristics and the level of stress and blood pressure were measured before and after cognitive distress game and relaxation. The gathered data were analyzed with frequency, $X^2$-test, Wilcoxon signed ranks test and Mann Whitney U test using SPSS 14.0 program. Results: Both level of stress and blood pressure displayed a statistically significant difference pre and post cognitive distress game. Relaxation had a statistically significant effect on level of stress. Relaxation, however, did not have statistically significant effect on blood pressure. Conclusion: The above results suggest that while relaxation was effective in reducing level of stress for college students, and therefore recommendable as a means to deal with stress. However, to investigate the effects on physiological index such as blood pressure, further research is needed.

  • ELISA kit for cortisol was developed and then evaluated. Polyclonal antihydrocortisone-3-(o-carboxymethyl)oxime BSA rabbit serum was used to coat the 96-well microplates. The minimum detection limit of the kit was 250pg of cortisol per milliliter. The within-run variation and the day to day variation of the ELISA system were 2.0 and 5.9 at maximum, respectively. The kit was used to determine whether salivary cortisol concentration could replace blood cortisol concentration in dexamathasone suppression test of dogs. Changes of cortisol concentration were measured in serum or saliva after intravenous administration of 0.01mg of dexamethasone per kilogram of body weight. Blood alone, saliva alone or both were collected at 0, 30, 60, 120, 240, and 360 minutes after injection of dexamethasone. The change in blood cortisol concentration was found to be suitable in dexamathasone suppression test of dogs, but the change in salivary cortisol concentration was not. The kit was also used to determine whether salivary cortisol concentration could be a stress index as well as blood cortisol concentration in dogs. Two types of trial were performed to estimate the stress either by blood or salivary cortisol concentration. The first trial was stress experiment by intravenous injection of 0.2IU of PZI-insulin per kilogram body weight. Either blood alone or saliva alone was collected at 0, 30, 60, and 90 minutes after insulin administration. Both blood and salivary cortisol concentration were found to be suitable index in estimating stress from hypoglycemia by injection of insulin. The second trial was stress experiment by electrical irritation. The dogs were irritated with anti-bark device for 10 seconds. Blood was collected before and at 2 and 5 minutes after electrical irritation. Saliva was collected before and at 3 and 6 minutes after electrical irritation. The blood cortisol concentration, but not the salivary cortisol concentration was found to be suitable index in estimating stress from electrical irritation. Cushing syndrome in a dog was also successfully diagnosed with this kit.

  • A health index was proposed that evaluates personal health state from both measured physiological variables and survey questions. Four health indices were defined such as cardiovascular index, stress index, obesity index, and management index. The total health index was calculated by summing these four health indices. Physiological variables such as blood pressure, heart rate variability(HRV), accelerated photoplethysmograph(APG), and body fat percentage were non-invasively measured and a survey questionnaire that asks personal health state, exercise intensity, and food preference was developed. The suggested health index was applied to thirty eight persons including 30 patients and 8 normal persons with an average age of 51.8. The average health index was estimated to be 75.1 out of 100 points. Young age group(below 50) and men group showed higher health indices than the aged(over 50) and women groups. The correlation coefficient between the cardiovascular index and stress index was found to be 0.513, which means stress is related to cardiovascular health state. The correlation coefficient between the measurements and survey questions was 0.385 for the cardiovascular index. It was as low as 0.182 for the stress index. More case studies may improve correlations between measurements and survey questions, and then, the current health index system may develop as an effective tool to evaluate personal health state.

  • A slit-flow apparatus with laser diffraction method has been developed with significant advances in ektacytometry design, operation and data analysis. In the slit-flow ektacytometry (or laser-diffractometry), the deformation of red blood cells subjected to continuously decreasing shear stress in slit flow is measured. A laser beam traverses a diluted blood suspension flowing through a slit and is diffracted by RBCs in the volume. The diffraction patterns are captured by a CCD-video camera, linked to a frame grabber integrated with a computer, while the differential pressure variation is measured by a pressure transducer. Both measurements of laser-diffraction image and pressure with respect to time enable to determine deformation index and the shear stress. The range of shear stress of 0 ${\sim}$ 35 Pa and measuring time is less than 2 min. When deforming under decreasing shear stress, RBCs change gradually from the prolate ellipsoid towards a circular biconcave morphology. The Deformation Index (DI) as a measure of RBC deformability is determined from an isointensity curve in the diffraction pattern using an ellipse-fitting program. The advantages of this design are simplicity, i.e., ease of operation and no moving parts, low cost, short operating time, and the disposable kit which is contacted with blood sample.

  • Diabetes mellitus (DM) is considered to be a serious metabolic disease which may cause systemic complications. The present study was designed to clarify a difference on stress, physiological variables and their correlation between diabetic (DM group) and nondiabetic adults (control group). The levels of body weight, waist circumference, blood pressure, body mass index, body fat mass, total cholesterol (TcH), triglyceride (TG), aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyltransferase (GGT), total bilirubin (TB), autonomic balance (AB), stress index (SI), fatigue index (FI), and heart rate (HR) were all significantly higher in the DM group than in the control group. However, the levels of autonomic activity (AA), stress resistance (SR), and electrocardiac stability (ES) were significantly lower in the DM group than in the control group. The percentages of persons with abnormal levels in the Tch, high density lipoprotein, low density lipoprotein, TG, AST, ALT and GGT were significantly greater in the DM group than in the control group. In the correlation of glucose and hemoglobin A1c (HBA1c) to stress indices, the DM group had a significant relationship with AB, SR, SI, FI, ES, and HR, whereas the control group had no significant relationship with these, excepting AB. These results suggest that DM was harmfully associated with body, biochemical and stress indices and that blood glucose and HBA1c levels must be exhaustively regulated.

  • Objectives This study was performed to investigate the effects of obesity, food, physical activity and stress on blood pressure changes for children and for adolescents. Methods The participants were the first and the fourth grade elementary school students and the first grade of middle school students. They were asked to measure the blood pressure, height, weight and were asked to complete questionnaires. Results The systolic and diastolic blood pressure of male was significantly higher than that of female and the prevalence of hypertension among the first and the fourth grade elementary school students and the first grade of middle school students were 15.6%, 13.6%, and 7.8%, respectively. Height, weight and body mass index (BMI) were highly correlated with the level of blood pressure. However, food, and physical activity, stress and depression were poorly correlated with the level of blood pressure. Conclusions This study proved that blood pressures in children and in adolescent were closely related with obesity, sex, and height.

  • In order to investigate flow characteristics of chicken blood in a micro tube of 100$\mu$m in diameter, in-vitro experiments were carried out using a micro-PIV technique. The micro-PIV system consists of a microscope, 2-head Nd:YAG laser, 12 bit cooled CCD camera and a delay generator. Chicken blood with 40% hematocrit was supplied into a micro tube using a syringe pump. The blood flow shows clearly the cell free layer near the tube wall and its thickness is increased with increasing the flow speed. The hemorheological characteristics of chicken blood, including shear rate and shear stress were estimated from the PIV velocity field data obtained. Since the aggregation index of chicken blood is less than 50% of human blood, non-Newtonian flow characteristics of chicken blood are smaller than those of human blood. As the flow rate increases, the degree of flatness in the velocity profile at the center region is decreased and the parabola-shaped shear stress distribution becomes to have a linear profile. Under the same flow rate, chicken blood shows higher shear stress, compared with human blood.
