The influences of acute respiratory and metabolic acid-base disturbances on the carotid, renal and coronary blood flow were measured in dogs. Respiratory acidosis was induced by artificial respiration with 8% CO2 -02 gas mixture and respiratory alkalosis was induced by hyperventilation under the control of respirator. Metabolic acidosis and metabolic alkalosis were induced by intravenous infusion of 0.3N hydrochloric acid and 0.6M sodium bicarbonate solution. To observe the effect of hyperkalemia, isotonic potassium chloride solution was infused. CVI electromagnetic flowmeter probes were placed on the left common carotid artery, left renal artery and left circumflex coronary artery. Each flow was recorded on polygraph. 1. The carotid blood flow showed rapid showed rapid and marked increase in acute respiratory acidosis. Even in the cases when arterial blood pressure was lowered during the state of respiratory acidosis, carotid blood flow increased. By the infusion of hydrochloric acid, carotid blood flow increased slowly and returned to the previous label after discontinuation of the infusion. Carotid blood flow also increased by the infusion of large amount of sodium bicarbonate, but it might be the combined effect of expansion of extracellular fluid and compensatory elevation of carbon dioxide tension. 2.The renal blood flow remained unchanged during the acute acid-base disturbances, suggesting effective autoregulation. Renal blood flow, however, increased very slowly when the infusion of potassium chloride continued for a long period. 3.Although less marked than the carotid blood flow, the coronary blood flow increased in the acute respiratory and metabolic acidosis. In asphyxiated condition, coronary blood flow increased most markedly and this might be the combined effect of hypoxia, hypercapnea, and lowering of pH. In summary, the carotid blowflow showed more marked change in the acute respiratory and metabolic acidosis than the renal and coronary blood flow. Respiratory and metabolic components of acid-base disturbances may influence the local blood flow concomitantly, there being more differences in the individual responses, but respiratory component manifested more rapid and marked effect than metabolic component.

The over-preparation of blood for elective surgery causes some problems such as returning of blood, inefficient task and loss of reagents. In recent blood transfusion practice, there has been changing patterns of blood use in elective surgery as various side effects of transfusion have become known and operation techniques are developed. This study was performed to evaluate the optimal utilization of blood for various elective and/or emergency surgery. We surveyed the quantity of blood transmitted to wards, returned to blood bank, and the number of crossmatching test done for the elective surgery of the patients at the D. University Hospital, the tertiary teaching hospital from August 1, 2001 to October 31, 2001. Crossmatched to transfusion ratio (C/T ratio) was calculated, in which C means the unit of accomplished crossmatching test and T means the unit of transfused blood component. The unit of transfused blood was analysed in terms of issuing time, sex, age, clinical department, and blood component type. The usage of bloods for the emergency surgery was also analyzed. In our study, C/T ratio was highest on Monday (1.54) and Tuesday (1.53), and higher in female patients(1.54) than in male patients (1.32). No significant relationship was observed between age groups. Among clinical departments, thoracic and cardiovascular surgery showed the highest C/T ratio (1.54). From above results, we could be sure that the management of transfusion practice was relatively appropriate in recent years, although the entire introduction of type and screen (T&S) method was desirable. If the T&S method is performed, the C/T ratio would be almost 1.00 and it would also relieve the duty of blood bank.

본 연구는 혈청지질과 비만 및 혈압과의 관련성을 검토하기 위하여 2011년 1월부터 12월까지 1년 동안에 대전광역시의 한 대학병원에서 종합건강검진을 받았던 30세에서 69세의 여성 1,381명을 대상으로 TC, TG, HDL-C, LDL-C, SBP, DBP, 비만도, 체지방률을 측정하여 혈청지질과 비만 및 혈압과의 관련성을 분석하였다. 연구결과, TC, TG, LDL-C, 비만도, 체지방률은 30대에서부터 60대에 걸쳐 단계적으로 상승하는 경향을 보였다. TC, TG 및 LDL-C는 혈압이 높아짐에 따라 상승하였으며, 정상혈압군에 비해 고혈압군에서 유의하게 높은 값을 보였다. TC, TG, SBP 는 비만도가 높아짐에 따라 단계적으로 상승하였고, 정상군에 비해 비만군에서 유의하게 높았으며, HDL-C는 비만도가 높아짐에 따라 감소하는 경향을 보였고, 정상군에 비해 비만군에서 유의하게 낮았다. TC, TG, LDL-C, 체지방률 및 비만도는 상호간에 유의한 정상관을 보인 반면, HDL-C와는 음의 상관을 보였다. 주성분분석 결과 제1주성분은 고혈압 인자, 제2주성분은 비만관련 인자, 제3주성분은 연령과 고지혈증 인자, 제4주성분은 고단백지콜레스테롤 인자가 선정되었다. HDL-C와 관련된 요인을 다중회귀분석을 사용하여 검토한 결과 HDL-C에 영향을 미치는 변수로는 연령, TC, TG 및 체지방률이 선정되었다. 위와 같은 결과는 비만도가 높고 혈압이 높은 군일수록 혈청지질치가 높아짐을 시사하고 있다.

The blood bank is a field of clinical pathology which requires the most accuratemaintenanceofrecording. Because the mistake in it is directly related to a patient's life. So, the computerization of the blood bank is urgent to maintain a log blook arid to compare the patient's current data with past result. We developed the blood bank management program using 32 bit minicomputer. This is composed of 4 parts; a management of routine test result, special test result, the blood issue and statistics. The management of routine test result handles the patient's information and blood typing and compares above results with the past one of same patient. The management of special test result are for special immunohematologic tests like an irregular antibody, Coombs' test, and etc. Blood issue part records the type of the blood bag, component, and the name of issuer. Statistic part are made to get statistics of each day and each month by the blood type, and the type the blood component. The program is secured by the maintenance of operator's operation history and thu provision of the security code to each operator, without which no one can enter the system and after the content. So the stability and reliability of the data is obtained. This program will be upgraded for bar-code using system in the near future.

This study was performed to investigate the blood contents of velvet antler and femoral venous blood in farmed elk (Cervus canadensis). Blood samples were collected from 12 young adult elk (3.5-4.5 years old) with a mixture of fentanyl-azaperone-xylazine (Fentazine$^{(R)}$). Values for hematological and clinicochemical components of the clinical healthy elk were determined. The results were grouped for comparison according to velvet antler and femoral venous blood. Lower mean platelet counts and fibrinogen values were found in the velvet antler than femoral venous blood (p<0.01). White blood cell count of velvet antler was significantly higher than that of femoral venous blood 0<0.05). The clinicochemical parameters (total protein, albumin, globulin, alanine aminotransferase, aspartate aminotransferasei blood urea nitrogens calciums magnesium and phosphonls) obtained in this study far farmed elk are consistent with the values between velvet antler and femoral venous blood.

Yoga is an ancient Indian system of life, encompassing various practices including practices for self-discipline and also for regulating the health states of the individual, being practiced for thousands of years. The present study aims at understanding the effect of two high frequency breathing practices over autonomic nervous system. Forty healthy male volunteers of age $21{\pm}2$ years with $9{\pm}3$ months of Yoga practice experience were recruited. The two high frequency Yoga breathing practices, kapalabhati (KB) and bhastrika (BH) were given as interventions randomly on either of the two days to minimise laboratory bias. They were assessed before and immediately after the interventions for heart rate, respiratory rate, heart rate variability (HRV), blood pressure and peripheral oxygen saturation. There was a significant increase in heart rate (p<0.01; p<0.001), systolic blood pressure (p<0.01; p<0.001), NN50 (p<0.01; p<0.001) component of HRV for both KB and BH groups respectively. There was a significant reduction in respiratory rate in both the groups (p<0.001, and p<0.05, BH and KB respectively) immediately following intervention. A significant increase in LF component of HRV and reduction in Diastolic blood pressure and high frequency (HF)component following KB was also observed (p<0.05, for all comparisons). The Mean peripheral oxygen saturation remained unaltered in both the groups (p>0.05).The results suggest that high frequency yoga breathing practices induce physiological arousal immediately as evidenced by increased blood pressure and heart rate. The sympathetic arousal was more following KB session as evidenced by an increased diastolic blood pressure, LF power and a decrease in HF power of HRV as compared to the BH session.

According to increase of domestic blood components use, the quality control of blood components is necessary to support good products. The purpose of this study is used to provide the producing index of the good product as compared with the accuracy and validity for the distribution of the quality control data. The value of mean, standard deviation, 95% confidence interval and degree of normal distribution of data were calculated by univariate procedure, the value of monthly mean of each blood centers per items were compared by Analysis of Variance(ANOVA) test for the degree of distribution. When there was difference among the mean values, the Duncan's multiple range test was done to confirm the difference. Finally, methods for accessing accuracy and validity of the quality data was done by the Contingency table test. The quality data of five blood centers was showed to the normal distribution and it was in a acceptable range. For each blood centers, the monthly means of Hematocrit(Hct), Platelet(PLT) and pH were not significantly different except Hct of C center, PLT of B, D center and pH of A center. The quality data per items was graded according to quality to six level. As a result of the comparative analysis, the monthly means of Hct of C and E center was significantly different higher than that of D, B and A center. The monthly means of PLT of A center and pH of C center was significantly different higher than that of the others. In the accuracy and validity of the quality control data, C center for Hct, A center for PLT and C center for pH were better than the other. The C blood center was most satisfiable and stable in the quality control for blood component. If the quality control method used in C blood center is adopted in other blood centers, the prepared level of the blood component of the center will be improved partly.
