얼마전 수혈로 인한 에이즈감염보도 이후 헌혈 혈액에 대한 의심이 커지고 있다. 현재 국내에서는 헌혈 혈액에 대해 어떠한 검사를 실시하고 있으며 왜 에이즈에 감염된 혈액이 수혈자에게 공급하게 되었는지 살펴보자.

This study evaluated the effects of adding blood levels to phycochemical properties, textural properties, and sensory characteristics of blood sausage. 4 treatment groups of blood sausage were produced, T1 (pork ham : pork blood = 60:15), T2 (55:20), T3 (50:25), and T4 (45:30). T1 had the highest moisture content, most cohesiveness, and gumminess, CIE L-value, CIE a-value, and CIE b-value of raw and cooked blood sausages. Protein content, fat content, ash content, and VBN values were not significantly different among the treatments. T4 was treated with the most added pork blood, and had the highest pH of raw and cooked blood sausages, cooking loss, and TBA values. T2's sausage was the hardest, but had more springiness, cohesiveness, gumminess, and chewiness than T4. The best scores were from T4 and had the most overall acceptability. The results of this study show that blood sausages containing 20% pork blood had higher improved quality characteristics in blood sausages.

Prothrombin Time (PT) is used as a measure of blood coagulation time. An optical analysis of the signal generating mechanism is described here for the reflection-type arrangement. Thromboplastin added into serum or whole blood initiates the coagulation process. We added a sufficient amount of magnetic particles into the sample before adding thromboplastin and subjected the mixture to a rotating magnetic field. The laser light gets reflected in a periodically modulated fashion with respect to the magnetic field rotation. Analysis of this decaying modulation could produce a reasonable coagulation time. We also introduce a simulation model to explain the signal generating mechanism using LightTools.$^{TM}$

국내에서 수혈되는 혈액에 대해서도 선진국에서 실시하고 있는 핵산증폭검사가 올해 하반기부터 적용될 예정이다. 핵산증폭검사의 실시로 혈액제제로 안전성은 그 어느 때보다도 높아질 예정이다.

The purpose of this study was to establish blood reference values for miniature pigs from various growth ages before pre-puberty. 12 miniature pigs from two swine farms were sampled by jugular venipuncture. Routine hematological and biochemical determinations were performed using whole blood and serum. For the variables examined in each age group the means and the standard deviations were calculated. In hematological values, there are significant changes (p<0.05) in RBC, hematocrit and platelet values in each group. In RBC and hematocrit values, 4-week group shows the lowest level, whereas in platelet values, 4-week group shows the highest level. In biochemical values, there are significant chnges (p<0.05) in glucose and GGT in each group, and in other biochemical values there are no significant changes during growing periods. The values presented here may be useful for knowing the normal values for miniature pigs and also screening the normal pigs in the early days of their life and during the developemental stages.

The purpose of this study is to examine factors affecting the life satisfaction of patients with hemodialysis in order to improve the quality of life for patients with hemodialysis. The subjects of this study are 168 patients who have undergone hemodialysis treatment in the hemodialysis rooms in D-city and C-providence. The data are collected between August 20th to September 5th, 2015. By using SAS 9.3 statistics program for data analysis, frequency, ${\chi}^2$-test, variance analysis and multiple regression analysis are conducted. Based on the analysis, it is found that family support(t=5.33, p<.001) and self-efficacy(t=3.52, p<.001) are statistically significant to the quality of life for male patients. Family support(t=2.58, p<.012) and adherence to self-care(t=4.08, p<.001) are statistically significant to the quality of life for female patients. With the study results, it suggests that nurses can help improve the affective and psychological stability of patients with hemodialysis by recognizing the factors affecting the life satisfaction of patients with hemodialysis by gender, developing and utilizing a nursing intervention.

Blood-sensitive reagents may exhibit false positives or negatives under the influence of substances other than blood. Since these reactions lead to the misinterpretation of blood evidence, it is essential to investigate the possibility of false-positive and -negative reactions of blood-sensitive reagents. Acidic hydrogen peroxide (AHP) is a recently discovered blood-sensitive reagent, and it is not yet known whether it causes false-positive or -negative reactions. To confirm this, 20 µL of blood was placed on metal surfaces, plastic surfaces, paper surfaces, paint surfaces, foods, vegetable oils, detergents, and petroleum hydrocarbons, and then AHP was applied. The blood was observed through an orange filter under a 505-nm light source, and no false-positive or false-negative reactions were observed with any of the substances/materials. However, it was confirmed that polyethylene terephthalate surfaces, polyvinylchloride surfaces, some paint surfaces, and foods exhibit their own photoluminescence under the conditions of blood observation, which interferes with blood observation.

This study was attempted to understand the phenomenon in depth by exploring the food craving of hemodialysis patients experienced during hemodialysis. Participants selected seven adult patients diagnosed with end-stage renal failure and receiving hemodialysis treatment from medical institutions. he collected data were analyzed using a phenomenological analysis method. As a result of the analysis the food craving of hemodialysis patients was derived into two categories included craving experience in the cognitive domain craving experience in the emotional domain and five themes: 'Looking for foods that are water and watery as a result of thirst','Food thoughts come to mind all day as a result of a limited diet', 'Always hungry', 'Faced with appetizing situations every hour', 'experiencing negative emotions due to failure to control meals'. The results of this study which sheds light on food craving from the perspective of hemodialysis patients should improve the understanding of hemodialysis patients appetite control water restrictions and dietary compliance and allow them to understand the food craving attributes of hemodialysis patients and provide customized education optimized for that extent when applying dietary education and nursing interventions suitable for them.

Surface modification of polypropylene hollow fiber membranes was performed in order to develop blood-compatibility biomaterials for use in the blood contacting surfaces and oxygenation membranes of a lung assist device (LAD), important medical device even more useful. Blood compatibility of materials was determined by using anticoagulation blood and evaluating formation of blood clots on their surfaces as well as activation of plasma coagulation cascade, platelet adhesion, and aggregation. It was verified that the number of platelets on the silicone coated fibers was significantly lower than that on untreated fiber membrane, indicating improved blood compatibility. It was also found that the polypropylene hollow fiber membranes using plasma treatment exhibited suppression of complement activation in blood compatibility test.

This study was performed to guide the effective utilization of blood and optimal blood ordering schedule for various elective surgeries, based on the analysis of 1.462 transfused surgical procedures and 5.933 blood units transfused during operation in the period of two years through January, 1987 to December, 1988 at Yeungnam University Hospital. The frequency of transfusion, and mean transfused units were evaluated and recommended blood unit for each surgical procedure was proposed. We assure that the successful establishment of this guideline can lead to substantial monetary saving, reduced blood outdation, and a decreased blood bank workload with a more appropriate allocation of the technician's time and effort.
