Iron deficiency anemia in pregnant women has been of great concern because of its negative effects on the outcomes of pregnancy. Much of evidence has shown that there are associations between pregnancy outcomes and maternal iron status. Maternal iron status might affect pregnancy outcomes through the iron status of the cord blood. In this study, we divided 91 subjects into two groups : the anemic and the normal groups. The groups were classified according to their hemoglobin(Hb) and hematocrit(Hct) values of the maternal blood in the third trimester of the pregnancies. We determined the parameters for the iron status of the cord blood and then analyzed the correlations between these parameters and the pregnancy outcomes. Mothers in the anemic group had a significantly higher parity number and a lower dietary score as well as a shorter duration of iron supplements consumed compared to those in the normal group. Maternal Hb values in the third trimester had positive correlations with the infant's head and chest circumferences, and the Hct values related positively to the infant's chest circumferences. On the other hand, Hb concentrations of the cord blood had positive correlations with the infant's height and head and chest circumferences. The Hct values of the cord blood had positive correlations with gestational periods and the cord lengths. These results suggest that the maternal iron status might influence fetal development through the iron status of the cord blood.

Little work has been done on the changes in the blood picture occurring at different ages in cattle. In our country Kim (1963) and Jeong (1965) recorded the blood picture of mature Korean native cattle and, recently, Mun et al. (1974) has recorded the blood picture of Holstein cows. And a comprehensive survey of the blood picture of Korean native cattle has not been made. The object of the present investigation was to make good this deficiency, and to suggest standards for the blood picture of Korean native cattle at frequent intervals from birth to maturity. The cattle were kept under average farming conditions in this country. Observations were made at the following ages: at birth; 1, 2 and 4 days; 1, 2 and 4 weeks; 2,4,6 and 9 months; 1, 2 and 3 years of age. Blood samples were drawn from the jugular vein. Erythrocyte enumerations, concentration of hemoglobin in blood and hematocrit values were made in usual manner. Erythrocyte counts increased from $8{\times}10^6/mm^3$ during the first week to a level of $10{\times}10^6/mm^3$ at 2 months of age, showing steady state untill 6 months of age; it then fell to adult level ($8{\times}10^6/mm^3$) at 9 months of age. Concentration of hemoglobin in blood and hematocrit values were closely related to the changes of erythrocyte counts. The values increased from 10 g/100 ml and 31~35 ml/100 ml during the early life to 11 g/100 ml and 38 ml/100 ml at 2 months of age, showing steady state untill 6 months of age; these then fell to adult level (10 g/100 ml and 31~34 ml/100 ml) at 9 months of age for concentration of hemoglobin in blood and hematocrit values, respectively. Mean corpuscular volume and mean corpuscular hemoglobin showed a common pattern. The values were $42{\sim}43{\mu}m^3$ and 12.4 pg during the early life and fell a little to 6~9 months of age; these then increased to reach adult levels of $43{\mu}m^3$ and 12.6 pg for mean corpuscular volume and mean corpuscular hemoglobin, respectively. Mean corpuscular hemoglobin concentration was little affected with age.

In this study, the two sampling methods for blood glucose measurement were evaluated in order to reduce pre-analytical error. For this purpose, glucose levels of Li-heparinized plasma (LHP) and Na-fluorinated plasma (NFP) in blood collected from healthy volunteers were determined by using routine hexokinase procedures. The percentage range of pre-analytical error was quantitated by comparing LHP glucose values with NFP glucose values according to delaying analytical time (0, 60, and 120 min). LHP glucose values were decreased by 6.6% in 60 min., 17.7% in 120 min, whereas NFP glucose values decreased by 1.1% in 60 min, 2.0% in 120 min. Therefore it may be recommended that the NFP sampling method should be used for routine blood glucose determination in diabetes mellitus diagnosis.

Purpose: This study aimed to identify the differences in blood pressure among adults in the community according to age and time of the blood pressure measurement. Methods: This was a secondary analysis study, using data from a 2015 community health survey, conducted by the Korea Centers for Disease Control and Prevention. The data of three-time-measured blood pressure were collected from 337 subjects, 25, 35, 45, 55, 65, 75 years old, which are median ages by each age group. Results: The primary systolic pressure was significantly higher than the secondary systolic pressure (t= 3.46, p= .001) and the tertiary systolic pressure (t= 4.83, p= .001). The secondary systolic pressure was higher than the tertiary measurement (t= 2.05, p= .041). There was no significant difference between the three-time-measured values for diastolic pressure. There was a significant interaction between measurement times and age in the systoic blood pressure readings (F= 1.95, p= .036). However, there was no significant interaction between measurement times and age in the diastolic blood pressure readings (F= 1.03, p= .418). Conclusion: The findings suggest that attention must be paid to the use of blood pressure values in studies or one-time-measured clinical blood pressure values. In particular, the differences in systolic pressure readings taken at different times in the older age groups were significant. Therefore, it is more important to carefully assess blood pressure in adults over the age of 45 compared to other age groups.

The present study was conducted in order to get the relationship of heartworm, Dirofilaria immitis and eosinophils in blood of Jindo dogs. Blood samples were taken from 141( man 31, womam 110) of yellow, 44 ( man 17, woman27) of white Jindo dogs in Jindo area. The results obtained in this study were summarized as follows : 1. There were no significant differences of the hematological values in comparison with others reported values, but the mean corpuscular hemoglobin concentration and the number of eosinophils were high in comparison with other reported values. 2. The mean values of total white blood cell count(P<0.05), neutrophil(P<0.05) and monocyte(P< 0.05) were that the yellow dogs and a tendency toward fisher values than the white dogs, but no significant differences were observed. 3. Age-related differences were detected for the total erythrocyte count(P<0.05), hemoglobin content (P<0.001), PCV(P<0.001) and the number of eosinophils(P<0.001). 4. The direct and indirect eosinophil counts were increased with age, there were no significant differences of the values between two groups. 5. Dirofilaria immitis was found in 34(18.4%), increased with age and were relatively significant differences in areas of the 185 Jindo dogs. 6. Survey for hematological values of Dirofilaria immitis infected dogs with direct and indirect method, mean values of eosinophil were 2,788/ ${\mu}l,$ 3,021/ ${\mu}$l, respectively. They showed that eosinophil had a tendency toward higher values than others, but others were no significant differences.

The blood components of not-young (young antler) were examined in the Red Deer. Blood samples were collected from the antler and jugular veins respectively. The hematological and serum chemical values were as follows; 1. RBC count of not-hyul (young antler blood) was significantly higher than that of jugular vein blood (p<0.05). However, fibrinogen concentration of rook hyul was significantly lower than that of jugular vein blood (p<0.01). WBC counts packed cell volume (PCV) and total protein fro) were not significant between nolo-hyul and jugular vein blood. 2. The concentration of phosphorous and magnesium of not-hyul were significantly higher than those of jugular vein blood (p<0.05). Albumin and glutamic oxaloacetic transaminase (GOT) of nolo-hyul were higher than those of jugular vein blood. But globulin and calcium concentration of not-hyul were lower than those of jugular vein blood. Blood urea nitrogen BUN) of rook-hyul was not significant when compared with that of jugular vein blood.

The study was undertaken to obtain indirect values of volume of packed red cell (VPRC) without centrifugation, using the erythrocyte sedimentation rate (ESR) of diluted blood in dogs. ESRs of diluted blood using the diluent of autologous plasma in which formed numerous RBC-rouleau clumps, autologous serum in which formed a few RBC-rouleau clumps, and 5% dextrose or 6% sucrose solutions in which formed numerous RBC-aggregation clumps, were accelerated. But, ESR of diluted blood using the 0.9% saline, D-S, ACD-B, CDP or D-PBS solutions were sluggish, because erythrocytes were dispersed in these diluents. Reliable values of VPRC on the basis of the correlating regressive equation to the ESR could be derived from values of$60^{\circ}$-angled-micro-ESR/40 min in the mixture, four parts of 5% dextrose solution and one part of whole blood. In the ESR values of diluted blood with low ratio, 1:1~3:1, $60^{\circ}$-micro-ESR was higher than $60^{\circ}$-Wintrobe-ESR. But, in the diluted blood with high ratio, 4:1~5:1, there was no different ESR values. For an aid of practical use, authers suggested a list of the $60^{\circ}$-micro-ESR/40 min in the diluted blood with equivalent VPRC of whole blood.

The purpose of this study is to derive indirect values of volume of packed red cell(VPRC), without centrifugation, from erythrocyte sedimentation rate(ESR) of blood diluted with isotonic dextrose solution in cattle. Each of ten blood samples taken from apprently healthy Korean cows and Holstein cows was used to produce eight different mixture of autologous plasma and blood corpuscles such that their values of VPRC lay between 15 to 50ml/100ml, and then each of the blood mixture was again diluted with 5% dextrose solution. The measurements of ESR using 45 degree-angled capillary hematocrit tube, 1.1~1.2mm bore, ($45^{\circ}$-micro-ESR) were practised for the diluted blood of various levels of VPRC under the ambient temperature of $10^{\circ}$, $20^{\circ}$ and $30^{\circ}C$. Reliable values of VPRC on the basis of the correlating linear regressive equation to the ESR could be derived from the values of $45^{\circ}$-micro-ESR/hr in the mixture of one part of whole blood and one part of 5% dextrose solution(1:1). For an aid of practical use, authors suggested a list of the $45^{\circ}$-micro-ESR/hr values of the diluted blood equivalent to VPRC of whole blood.

Objectives: This study aimed to assess a Qi Blood Yin Yang evaluation method systematically and objectively and to identify the correlation between the Qi Blood Yin Yang deficiency pattern (QBYYDP) and facial color. Methods: Thirty-seven participants (17 males, 20 females) were enrolled in this study. Twenty-four (10 males, 14 females) had ages from 40 to over 60, and 13 (7 males and 6 females) were in their twenties. After sufficient rest, facial images were taken with a camera. Based on the results from a questionnaire survey, we divided the participants into five groups: the normal and the Qi-, Blood-, Yin-, and Yang-deficient groups, after which the relationships between the L, 'a', and 'b' values in the Lab color system and the characteristics of the participants in each of the deficient groups were elucidated using a facial color analysis program. Results: The color analysis for Qi-deficient (QD) participants revealed that the L value was fairly decreased in comparison with the normal participants, but the 'a' and 'b' values were almost the same. A comparison between the normal and the Yang-deficient (YaD) groups revealed that the L values were somewhat lower compared to the normal group, but the 'a' and 'b' values were not statistically different. For the Yin-deficient (YiD) group, the L value was slightly lower compared to the normal group, but the 'a' and 'b' values were almost the same and the R values were slightly increased. For the Blood-deficient (BD) group, the L values were slightly increased compared to the normal group, but the 'a' and 'b' values were decreased slightly. Conclusion: This study obtained objective, reliable data for judging the QBYYDP by using facial images and a color analysis program. However, further study with at least 10 or more subjects in each of the deficient groups is necessary to confirm our findings.
