Optimum drying conditions to utilize porcine blood from slaughter house for blood meals, and the effects of blood meals on growth in broiler chicks were investigated. Moisture and protein con-tents of slaughter porcine blood were 79.8 and 16.4%, respectively. The protein contents of the flash dried blood meals at 80˚C were not different from those of the spray dried blood meals at 160 and 190˚C, but higher by 17% relative to those of the spray dried blood meals at 80 and 120˚C. Results from protein analysis by SDS-polyacrylamide electrophoresis showed that flash dried blood meals at 80˚C and spray dried blood meals at 160˚C were better than spray dried blood meals at 80, 120 and 190˚C in terms of protein quality. In Feeding Trial I with broiler chicks, body weights of chicks fed 2, 4 and 6% flash dried blood meal diets at 80˚C were increased at 35 days by 5.6, 7.9 and 4.0%, respectively, compared to control group(P<0.05). In Feeding Trial II, body weights of chicks fed 4 and 6% flash dried blood meal diets at 80˚C were increased at 42 days by 4.9 and 5.3%, respectively, compared to control group(P<0.05). Feed conversion ratios of chicks fed diets 4 and 6% flash dried blood meal diets at 80˚C were significantly improved at 42 days by 7.0 and 3.7%, respectively, compared to that of control group(P<0.05). The optimum drying condition of slaughter porcine blood seemed to be the flash drying method at 80˚C

The Standardization of terms in The Pulse studies(脈學) is a need for development of learning. This study, for the correction of existing misused terms in The Pulse studies, we study on modernly and objectively the terms in The Pulse studies. By a focus of ${\ulcorner}$The Pulse Studies of Bin-Ho(瀕湖脈學)${\lrcorner}$, we studies on the new classification of pulse condition. The error of a existing technical books on Pulse studies begin that the classification of pulse condition is not establish a Standardization. For the correction of existing misused terms in The Pulse studies, we study on the pulse condition is expressed objectively a blood vessel that it is a subject of pulse condition. The expression of blood vessel contain a depth of blood vessel, a speed of pulsation, a curve of blood vessel, thickness of blood vessel, a diameter of blood vessel in expand and contract of blood vessel, a interval in expand and contract of blood vessel, a distinctness on a boundary of blood vessel, a speed of blood flow in blood vessel, a volume of blood flow in blood vessel, a condition of blood in blood vessel, a propelling power of blood vessel. These is standard of the new classification of pulse condition.

Malignant tumor have hypoxic cell fraction, which makes radio-resistant and hypoxia in tumor is a result from the blood flow decrease caused by increase in blood flow resistance. Blood viscosity increase is major factor of increased blood flow resistance and it could be attributed to the decrease in blood deformability index. For the evaluation of the change of blood viscosity and blood deformability in oral squamous cell carcinoma, we perform the test of the change of those factors between the normal control group and oral squamous cell carcinoma cell patient group. Relative viscosity measured against distilled water was $5.25{\pm}0.14$ for normal control group, and $5.78{\pm}0.26$ for the SCC patient group and there was statistical significance between the groups. However, there was no significant difference between the groups in blood viscosity between the groups by tumor size (T1+T2 vs T3+T4). Also, there was no significant difference between the normal control group and SCC patient group in blood deformability index and between the groups by tumor size (T1+T2 vs T3+T4). Increase in blood viscosity was confirmed with this study and it can be postulated that modification blood viscosity might contribute to decrease of hypoxia fraction in oral squamous cell carcinoma, thus improve the effect of radiotherapy and it can be assumed that the main factor of blood viscosity increase is not decrease of blood deformability in oral squamous cell carcinoma.

Objective: The current study was to test if the developed sphygmomanometer was working well and blood pressure information could be collected and monitored systematically through the internet. We tested if the sphygmomanometer and services for blood pressure controlled high blood pressure significantly and the ubiquitous monitoring could be used further. Methods: Kyungwon University, KT Co., Gil Medical Center, LIG Nex1 Co., and Sujeong Health Center conducted an ubiquitous high blood control project in Sujeong-gu, Sungnam, Korea from Mar. 5 to May 16. We developed and applied sphygmomanometer. We distributed the devices to 27 high blood pressure patients. The blood pressures of the residents were monitored through the internet when they measured blood pressures in their homes. A nurse monitored and consulted their blood pressures in the monitoring center in Kyungwon University during the demonstration period. The consultant called them and consulted on their blood pressures in few seconds they used the sphygmomanometers. For the significance of change in blood pressure, we tested statistically with Generalized Additive Model(GAM) and Multi-level Analysis. Results: Both GAM and Multi-level Analysis showed that the blood pressures of persons with ubiquitous blood pressure management decreased significantly as time passed. Conclusions: The internet monitoring and services are considered to be promising because most of the participants were satisfied especially because somebody was caring their health. The decrease of blood pressures was significant by GAM and Multi-level Analysis. Thus, we can apply ubiquitous blood pressure management to health promotion projects.

To show the distribution and change of blood pressure according to age and to find factors affecting the level of blood pressure in primary school children, a follow-up study was conducted from 1986 to 1989 on 401 first grade children attending primary school in Kangwha County in 1986 and their parents. The blood pressure of the children was significantly increased according to age. The average annual increase was 1.8mmHg in systolic blood pressure and 2.5mmHg in diastolic blood pressure. The level of blood pressure did not show any significant difference in both sexes. Among children who were at or above the 80th percentile of blood pressure in the first grade, 35 and 30% of them have remained at the same level of systolic and diastolic blood pressure respectively in the fourth grade. But we could not find any significance in the tracking of blood pressure of children who were at or above the 90th percentile of blood pressure in the first grade. Weight and pulse rate were shown to be significant factors affecting systolic blood pressure in children of both sexes and mother's blood pressure and skinfold thickness were also affected systolic blood pressure in girls. The variables significantly affecting diastolic blood pressure were arm circumference and pulse rate for boys and height and pulse rate for girls.

The x-ray PIV method was improved for measuring quantitative velocity fields of real blood flows using a coherent synchrotron x-ray source. Without using any contrast media or seeding particles, this method can visualize flow pattern of blood by enhancing the phase-contrast and interference characteristics of blood cells based on a synchrotron x-ray imaging mechanism. The enhanced x-ray images were achieved by optimizing the sample-to-scintillator distance, the sample thickness, and hematocrit. The quantitative velocity fields of blood flows inside opaque tubes were obtained by applying a 2-frame PIV algorithm to the x-ray images of the blood flows. The measured velocity field data show typical features of blood flows such as the yield stress effect. The non-Newtonian flow characteristics of blood flows were analyzed using the x-ray PIV method and the experimental results were compared with hemodynamic models.

We studied blood salvage effect of Cell Saver Apparatus[CSA with adult cardiac patients. This study compares blood salvage in two groups of patients undergoing valve replacement or congenital cardiac operation.Group 1 is composed with 60 patients operated during 1991-1992 using CSA. Group 2 is composed with 60 patients operated during 1990-1991. No special effort was made to salvage blood in Group 2. The average requirements in Group 1 were approximately one-fourth the amount of RBC products by Group 2. The hospital course, blood chemistry level were comparable for the two groups. CSA produced blood was concentrated, well oxygenated blood and the average amount was 830 ml. Any complication was not detected in transfusion of CSA produced blood. This study shows that CSA allows safe and practical blood salvage during adult cardiac operations.

Hematopoietic stem cells in bone marrow form all kinds of blood cells. In traditional medicine, functions of bone marrow cells are very similar to those of Essence(精) which is a fundamental factor of physical development and reproduction. Our experiment examined the effect of deer blood on aplastic anemia induced mouse using cyclophosphamide 150 mg/kg i.p injection before experiment and then another cyclophosphamide 120 mg/kg i.p injection on day 10. Then we administrated dried deer blood in distilled water for 5 days, 9 days and 10 days. We examined blood and marrow samples. In results, deer blood showed a trend of effectiveness on recovery of red blood cells and erythropoietin although they were not statistical significant. And deer blood did not show changes in CD34.
