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.

Changes in gastrointestinal tissue blood volume induced by variations of venous pressure between 6 and 40 mmHg were studied in 32 rabbits. Venous pressure lowering was produced by withdrawal of appropriate volume of blood and venous pressure elevation was obtained by partial occlusion of intra-thoracic vena cava inferior. Estimation of regional tissue blood volume was performed by means of regional distribution of injected $Cr^{51}-labeled$ red blood cells. The following results were obtained. 1. At the normal control venous pressure value of 18 mmHg, spleen showed the highest value of tissue blood volume expressed on weight basis, namely, $111{\mu}l/gm$, Liver tissue blood volume was $95\;{\mu}l/gm$, small intestine 24 and stomach $21\;{\mu}l/gm$, respectively. 2. Linear relationships were observed between venous pressure change and gastrointestinal tissue blood volume. The coefficients of correlation were: in spleen r=0.723; in liver r=0.791; in stomach r=0.704, respectively. In small intestine the relationship was less clear and r=0.358. Tissue blood volume of extrabdominal tissue, such as M. gastrocnemius was not influenced by venous pressure change. 3. The highest change in tissue blood volume expressed on weight basis was observed in spleen. The liver tissue showed the next highest change. Change in total tissue blood volume, however, was greatest in liver and next greatest in small intestine. This was interpreted by the fact that total weight of these two organs was much greater than that of spleen. 4. The mechanism that the change in tissue blood volume lies in the venous system which has a great compliance was discussed.

It was confirmed that we got somewhat different results even though we performed same items with same methods from capillaries and venous blood of healthy 72 cases. Items which capillaries blood has higher value than venous blood are the numbers of erythrocyte, lymphocyte, basophil, hematocrit, MCHC and RDW. Total numbers of RBC (p<0.035), lymphocyte and basophil are shown statistically significance. Items which venous blood has higher value than capillary blood are the numbers of platelet (p<0.00) and neutrophil (p<0.01). Fallible items in clinics can be shown the numbers of RBC, platelet, lymphocyte and neutrophil because we got somewhat different results even though we performed same items with same methods from capillaries and venous blood, respectively. It is necessary to choose the clear criteria and normal value depends on clinical specimen as the number of platelets are measured with an abnormal value shown over 40% down. As normal difference according to each item and method is currently acceptable and applicable in clinics, it is considered that a new normal value depends on clinical specimen should be established and is to be useful positively in clinics.

There have been reports of successful bone formation with sinus floor elevation by simply elevating the maxillary sinus membrane and filling the sinus cavity below the lifted sinus membrane with a blood clot. But, in a review of the current literature, we found no animal study that substantiated blood clot's ability in this respect. The aim of this study was to investigate the effect of the method of maxillary sinus floor augmentation using the patient's own venous blood in conjunction with a sinus membrane elevation procedure. An implant was placed bilaterally in the maxillary sinus of six adult mongrel dogs so that it protruded 8 mm into the maxillary sinus after sinus membrane elevation. On one side of the maxillary sinus, the resultant space between the membrane and the sinus floor was filled with autologous venous blood retrieved from the dog. On the opposite side, the maxillary sinus was left untreated as a control. The implants were left in place for six months. The mean height of the newly formed bone in the sinus was 3.7 mm on the side without venous blood and 3.5 mm on the side with venous blood (p>0.05). There was no difference between the two sides regarding new bone height in the sinus. Our results indicate that filling the space between the lifted sinus membrane and the sinus floor with venous blood has no effect on bone formation around implants placed in the maxillary sinus cavity.

목적 : 감염이 있는 환자들을 진단하는데 있어 CRP 검사 결과는 치료의 방향을 결정하는데 많은 도움을 준다. 하지만 영 유아에게 있어서 채혈의 어려움 때문에, 정맥혈 검사를 대채할수 있는 모세혈 채혈이 시도되고 있다. 이번 연구에서는 모세혈 채혈을 통한 CRP 검사 결과가 정맥혈 검사 결과와 차이가 있는지 비교평가 하였다. 방법 : 인하대병원 응급의료센터, 소아청소년과에 내원하거나 입원한 100명(0-14세, 남녀 47 : 53)을 대상으로 정맥혈은 Hitachi 7180$^{TM}$ (Hitachi, Tokyo, Japan), 모세혈은 LC-178CRP$^{TM}$ (Horiba Ltd., Kyoto, Japan, LC-178CRP)장비를 사용해 검사하였다. 통계적 분석방법은 교차분석을 통하여 정맥혈과 모세혈의 CRP 판독차이를 검정하였으며, 회귀분석 및 Bland Altman plot 방법을 통하여 일치도를 평가하였다. 결과 : 교차분석으로 모세혈과 정맥혈 검사의 CRP 판독차이를 검정한 결과 일치도는 90.63%로 유관한 관계성이 있었다(P<0.0001). Bland Altman Plot으로 분석한 결과 95% 신뢰구간의 일치 한계선내에서 측정되었다. 단순회귀모형으로 분석한 결과 기울기($\beta$)는 1.3434였으며, 결정계수($R^2$)는 0.9888로 매우 높은 선형관계를 확인할 수 있었다. 또한 정맥혈에서의 값은 모세혈에서 시행한 값보다 평균적으로 높음을 확인할 수 있었다. 결론 : 모세혈의 CRP는 정맥혈과 매우 높은 상관관계를 보였다. 일반적으로 정맥혈 검사를 하는것이 더 좋겠지만, 채혈이 어려운 경우 LC-178CRP$^{TM}$를 이용한 모세혈에서의 채혈은 정맥혈 검사를 대신할 수 있는 간편한 방법으로 생각된다.

$^{18}F$-FDG PET 검사는 포도당 대사를 이용하여 전신의 종양을 평가하는 검사로 전처치 과정에서 혈당 측정의 중요성이 매우 높다. 혈당 수치가 높은 상태에서 FDG를 투여하면 FDG와 혈중 포도당이 세포 내 흡수에 서로 경쟁하게 되고 종양으로의 FDG 섭취가 감소되어 정확한 검사가 되지 않을 가능성이 있다. 혈당 측정에 사용되는 혈당 측정 검사지는 경우에 따라 모세혈관혈 전용 측정 검사지와 모세혈관혈과 정맥혈을 모두 측정 가능한 범용 측정 검사지로 구분되어 있는데, 정확한 혈당 측정 검사지(스트립)의 사용에 따른 혈당 수치의 차이를 비교 분석 하였다. 연구 대상은 2010년 3월부터 4월까지 서울아산병원 핵의학과에서 $^{18}F$-FDG whole body PET 검사를 시행한 환자 중 46명(남자: 32명, 여자: 14명, 평균연령 $57.3{\pm}12.3$세) 을 연구의 대상으로 하였다. 실험기기는 Abbott사의 Optium Xceed혈당 측정기를 이용하였고, 모세혈관혈과 정맥혈을 모두 측정 가능한 범용 측정 검사지를 사용하여 동일 환자의 모세혈관혈과 정맥혈의 혈당 수치의 차이를 분석하였다. 또한, 모세혈관혈 전용 측정 검사지를 사용하여 동일 환자의 모세혈관혈과 정맥혈의 혈당 수치의 차이를 비교 분석하였다. 분석방법은 MINITAB 통계 프로그램을 이용하여 paired t-test 검정을 시행하였다. 모세혈관혈과 정맥혈을 모두 측정 가능한 범용 측정 검사지로 측정한 동일 환자의 모세혈관혈과 정맥혈의 혈당 수치는 각각$95.2{\pm}12.4$ mg/dL, $104.1{\pm}14.4$ mg/dL (t=8.0, p<0.001)로 통계적으로 유의한 차이가 있었다. 모세혈관혈 전용 측정 검사지로 측정한 동일 환자의 모세혈관혈과 정맥혈의 혈당 수치는 각각 $91.5{\pm}13.6$ mg/dL, $108.1{\pm}16.2$ mg/dL (t=9.2, p<0.001)로 통계적으로 유의한 차이가 있었다. 선행연구에 의하면 모세혈관혈과 정맥혈의 혈당 수치는 여러 가지 이유로 인해 차이가 있는 것으로 보고 되었고 본 연구의 결과도 유사한 차이를 확인하였다. $^{18}F$-FDG PET 검사 전에 혈당 수치를 측정할 때 모세혈관혈 전용 측정 검사지로 정맥혈의 혈당을 측정하는 것은 부정확한 혈당 수치를 측정할 수 있으므로 주의해야 할 것이다. 그러므로 적합한 측정 검사지와 규정된 측정절차를 이행하는 것이 측정 편차를 줄일 수 있어 PET 검사의 전처치를 보다 명확하게 확인할 수 있을 것이다. 또한, 혈당 측정 시에 혈액 채취 부위를 모세혈관 또는 정맥혈관 중에서 항상 동일한 부위에서 측정하는 등의 표준화 과정이 필요할 것이다.

Appreciation of the large volume deficits which may occur in surgical or trauma patients due to blood loss has led to vigorous transfusion techniques designed to overt hypovolemic shock and ischemic damage to vital organs which may develop in minutes during the hypovolemic state. In a significant proportion of patients treated with massive rapid blood or fluid transfusion, hypervolemia occurs and life threatening pulmonary edema may develop. Especially, hypervolemia may occur during transfusion for preventing development of the so-called low output syndrome following cardiac surgery. However, the most effective indicator which reveals the adequate level of transfusion is not settled yet. The present study was aimed to compare the effectiveness of the indicators suggested thus far and to determine the most sensitive one. Eight dogs were experimentally studied in terms of left atrial pressure, pulmonary arterial systolic pressure, central venous pressure, mean systemic arterial pressure and heart rate before and after induced hypervolemia with infusion of 600ml heparinized homologous blood. Immediately after induced overtransfusion of the blood, pulmonary arterial systolic pressure increased 75.0%, in omparison with the control before transfusion, left atrial pressure 58.8%, central venous pressure 44.6%, and mean systemic arterial pressure 10.1%, one hour after transfusion, pulmonary arterial systolic pressure 40.0%, left atrial pressure 21.2%, central venous pressure 14.5%, and mean systemic arterial pressure 3.2%, central venous pressure 14.5%, and mean systemic arterial pressure 3.2%, respectively. Heart rate showed no significant change throughout the experiment. These result suggested that the changes of the pulmonary arterial systolic pressure is the most sensitive indicator for detection of hypervolemia during blood transfusion.

Objectives: This study aims to evaluate the blood concentrations and dietary intake for 24-hour food duplicate of low level polycyclic aromatic hydrocarbons (PAHs). Design: The geometric means of the blood concentrations and dietary intake of 16 PAHs in college student candidates were simply compared with instrumental detection. Methods: The concentrations of 16 PAHs in venous blood and 24-hour food duplicates were analyzed with head-space solid phase microextraction (HS-SPME) of gas chromatography-mass spectrometry. Results: Naphthalene, acenaphthylene, pyrene, benz(a)anthracene, chrysene, and acenaphthene among the 16 analyzed PAHs were simultaneously detected both in venous blood and 24-hour food duplicate samples. Conclusion: The main exposure source of the six PAHs is thought to be oral intake from food through low level non-occupational exposure.

Renal failure patients have to operate arteriovenous graft for hemodialysis. Blood flow characteristics influence the patency rate of arteriovenous graft. Numerical investigation is performed with the arteriovenous graft according to injection of blood. As a result, when the injection is not applied to venous graft, the low wall shear stress region appears at venous anastomosis. It may cause intimal hyperplasia at venous anastomosis.
