Objectives: Blood lead and hyperhomocysteinemia have been found to be associated with cardiovascular disease. The objective of the present study was to assess the relationship of lead biomarkers on plasma homocysteine and blood pressure. Methods: To evaluate the effect of lead biomarkers including blood lead on plasma homocysteine and blood pressure in retired lead workers, 66 retired lead workers without any occupational exposure to organic solvent, mercury and arsenic were agreed to participate this study. For the control subjects 42 controls were recruited from same area of retired lead workers with consideration of demographic characteristics. Results: The mean levels of blood lead and ZPP of retired lead workers were significantly higher than control group. There were positive significant correlations between blood lead and plasma homocysteine, also systolic and diastolic blood pressure. The multiple linear regression analysis also reveled that plasma homocysteine was significantly associated with blood lead after adjusting for age, gender, body mass index, lead exposure, smoking and drinking. Diastolic blood pressure was significantly associated with blood lead, plasma homocysteine, and total cholesterol; whereas, systolic blood pressure was significantly associated with plasma homocysteine only. Conclusions: Blood lead showed significant association with plasma homocysteine and blood pressure even after more than mean 10 years from their retirements.

The various blood pressure simulators have been proposed to evaluate and improve the performance of the automatic sphygmomanometer. These have some problems such as the deviation of the actual blood pressure waveform, limitation in the blood pressure condition of the simulator, or difficulty in displaying the blood flow. An improved simulator using disturbance observer is proposed to supplement the current problems of the blood pressure simulator. The proposed simulator has an artificial arm model capable of feeding appropriate fluids that can generate the blood pressure waveform to evaluate the automatic sphygmomanometer. A controller was designed and thereafter, simulation was performed to control the output signal with respect to the reference input in the fluid dynamic model using the proposed proportional control valve. To minimize the external fluctuation of pressure applied to the artificial arm, a disturbance observer was designed on the plant. A hybrid controller combined with a proportional controller and feed-forward controller was fabricated after applying a disturbance observer to the control plant. Comparison of the simulations between the conventional proportional controller and the proposed hybrid controller indicated that even though the former showed good control performance without disturbance, it was affected by the disturbance signal induced by the cuff. The latter exhibited an excellent performance under both situations.

Purpose: The purpose of this study was to examine the effects of drinking water on the change in blood pressure after spinal surgery. Methods: A quasi-experimental nonequivalent control group, pretest and posttest design was employed. Subjects were consisted of 40 elderly patients who underwent spine surgery (20 in the experimental group, 20 in the control group). Data were collected from May 9th to September 30th, 2013. The experimental design involved patients drinking 400 mL of water in 5 mins after surgery and the blood pressure was measured in a standing position following the first 30 minutes after surgery. Control group received the same treatment and care as experimental group, except for the water intake. Data were analyzed using SPSS WIN 19.0 for $x^2-test$, t-test and independent t-test. Results: Experimental group with water intake demonstrated a significant higher level of systolic blood pressure compared to the control group (t=9.065, p=.005), but showed a non-significant level of diastolic blood pressure. Conclusion: This study indicates that water intake can be utilized as a useful nursing intervention to monitor changes in systolic blood pressure in elderly patients after spinal surgery.

Objectives : The purpose of this study was to investigate effect of Exercise on inhibition Blood pressure by Auricular-plaster Vaccaria seeds Methods : This study picked 40 peoples from 20 May 2009 to 30 June 2009 and experiment them. Attached Vaccaria seeds to auricular acupuncture of the experiment group. Did not attach them to the control group. Them to exercise using a Bike-Ergometer exercise. I measured their blood pressure before the exercise, 15 minutes after the exercise and 30 minutes after the exercise. I compared the difference between the systolic blood pressure and diastolic blood pressure. The method to choose the subjects was Random allocation. Results : 1. Comparing the systolic blood pressure of the experiment group and the control group, the average systolic blood pressure of the experiment group, who did the Bike-Ergometer exercise putting on Auricular-plaster Vaccaria seeds, was 125.45 mmHg before the exercise, 121.20 mmHg 15 minutes after the exercise and 120.30 mmHg 30 minutes after the exercise. Terefore, the group's systolic blood pressure after the exercise was more controlled than the systolic blood pressure before the exercise. The control group's systolic blood pressure increased compared to the beginning. To measure the change before and after the exercise, I carried out paird-t test. The result was statistically significant. 2. Comparing the diastolic blood pressure of the experiment group and the control group, the average diastolic blood pressure of the experiment group, who did the Bike-Ergometer exercise putting on Auricular-plaster Vaccaria seeds, was 81.45 mmHg before the exercise, 79.65 mmHg 15 minutes after the exercise and 79.05 mmHg 30 minutes after the exercise. As a result of carrying out paird-t test to measure the change of the diastolic blood pressure, the change of the dilating blood pressure was statistically significant. However, the difference of the dilating blood pressure between 15 minutes after the exercise and 30 minutes after the exercise was not statistically significant. Comparing the systolic blood pressure and the diastolic blood pressure of the experiment group and the control group, the blood pressure of the experiment group, who did the Bike-Ergometer exercise putting on Auricular-plaster Vaccaria seeds, decreased compared to the beginning and the blood pressure of the control group, who did not put on Auricular-plaster Vaccaria seeds, increased compared to the beginning. Conclusions : The hypothesis was supported that the increase of the systolic and diastolic blood pressure of the experiment group, putting on Auricular-plaster Vaccaria seeds, was more controlled than that of the control group. In future, it can be medically used by verifying the various effects through repeated studies.

Purpose: The purpose of this study was to examine preventive effects of water drinking on postprandial fall of blood pressure in the elderly. Method: Participants were 25 elders who had experienced postprandial fall of systolic blood pressure of more than 15mmHg in a previous study. Within subject repeated measures design using random order allocation was used to control extraneous variables among participants. During the experiment, each participant had to drink 400mL water before lunch, whereas when in the control, they only had their lunch. Blood pressure and heart rate were measured for both times before lunch and at 15 minutes intervals up to 90 minutes after lunch. Data were analyzed using descriptive statistics, repeated measures of ANOVA, paired t-test and Bonferroni adjustment as Post-hoc analysis. Results: Water drinking before lunch elicited significant pressor effects by increasing systolic and diastolic pressure $13.9{\pm}4.7/5.2{\pm}2.2mmHg$ compared blood pressure during the control p<.005, p<.022. Heart rate, however, did not change significantly at either time. Conclusion: Drinking water before meal is recommended for elders who experience postprandial hypotension. However, the appropriate volume of water to prevent postprandial fall in blood pressure should be further studied.
