This study was conducted to investigate the effects of passive inhalation of cigarette smoke and the correlation between change of flicker value and active or passive smoking in poorly ventilated room. Forty five male students were tested by divided into four experimental groups composed of active and passive smokers and three control groups. Each four experimental groups were exposed to smoke for Two hours in enclosed room. Vital capacities, flicker values, blood carboxyhemoglobin levels and carbon monoxide concentration in room air were estimated before, during and after the exposure, and amounts of smoking or smoke exposure during two hours were also noted. The results obtained were as follows; 1. Concentration of carbon monoxide in air and increase of blood carboxyhemoglobin level (% COHb) were positively correlated with smoking amount. 2. Increase of blood carboxyhemoglobin in passive smokeres, in average, were about seventy six percent of that in smokers, as 2.2% vs. 2.9%. 3. Comparison with published data showed that Peterson's equation gave most similar result to this study in estimation of increase of blood carboxyhemoglobin level. 4. During the exposure, flicker values fell steadily in both experimental groups and control groups as time passed. Flicker values were, however, elevated again in experimental groups after exposure, despite the fact that values still fell in control groups. 5. Blood carboxyhemoglobin and flicker value were negatively correlated and this correlationship was stronger in passive smoker than in active smoker. 6. Multiple regression equation between flicker value and exposure time and blood carboxyhemoglobin level was expressed as: Flicker value=41.6-0.2 COHb%-0.9Hour, 7. In general, it is suggested that biological criteria would be more preferrable than chemical criteria in establishment of statutory limitation of smoking in enclosed spaces.

Hematological, chemical and functional characteristics of porcine, chicken and duck blood were evaluated. A porcine blood sample showed the most abundant red blood cell, hemoglobin concentration, packed cell volume and plasma protein content as well as its freeze-dried blood possessed the highest contents of protein, fat, Cu and Cr with the highest percentage of heme iron (p<0.05). Unlike porcine blood, chicken blood showed a well balance in some essential amino acids, specifically for a higher isoleucine content (p<0.05). Furthermore, it possessed the highest contents of carbohydrate, Zn and non-heme iron (p<0.05). The most rapid response to form a strong gel, especially at $70^{\circ}C$ and $80^{\circ}C$, was found in chicken blood, followed by duck and porcine blood, respectively. The result of emulsion activity index (EAI) and emulsion stability index (ESI) at the low protein concentration indicated that chicken blood had the most superior emulsion properties (p<0.05). Regarding duck blood, it exhibited the highest content of Mg and Mn (p<0.05). Moreover, duck blood had similar foaming properties to porcine blood in which they showed higher values than chicken blood (p<0.05). Specific characteristics of blood were therefore diminished by animal species in which this information could be used as food supplementation or product development based on their potential applications.

Bisphenol A (BPA) is a monomer used in the manufacture of a multitude of chemical products, including epoxy resins and polycarbonate. The objective of this study was to evaluate the effects of BPA administration on reproductive characteristics and blood hematological and chemical values in offspring of pregnant dams treated with BPA. BPA was administrated to pregnant mice by intraperitoneally injection with 0, 0.05, 0.5 and 5.0 mg/kg B.W. for 5 times at 3 days interval on gestation days 1-16. There were no treatment-related effects of BPA on reproductive organ weight in male offsprings at 45 days-of-age, but body weight was the lowest in 5.0mg BPA group when compared to other groups (P<0.05). No differences in semen characteristics (sperm concentration, viability, motility and abnormality) were observed between the control and BPA treatment groups. The WBC, HB, HT, MCV, MCH, MCHC, albumin, BUN and total protein of blood hematological and chemical values in male offsprings were not difference for any treatment groups, but RBC value in BPA groups was significantly increased comparing to the control group (P<0.05). The PLT value was slightly higher in 5.0mg BPA groups than in any other group, but not significantly difference among the experimental groups. In female offsprings, the effects of BPA didn't affect to the body and ovary weight, but the uterus weight in 5.0mg BPA group was slightly heavier than that of control group (P>0.05). No statically significant difference in blood hematological values in female offsprings were observed between the control group and BPA groups, but the concentration of albumin and BUN were significantly higher in 0.5mg BPA group when compared to control and other BPA treatment groups (P<0.05). The histological evaluation of testis and ovary in growing offspring at 45 days-of-age was not difference between the control group and BPA groups, but endometriosis of the uterus in female offspring was dramatically increased in 0.5 and 5.0mg BPA groups. These founding suggest that low concentration of BPA might not have a important role on reproductive ability or blood metabolite in offspring of pregnant dams treated with BPA.

In order to detect the influence of overdosed combelen on the Korean native goats, 5mg of combelen per kg of body weight were injected intramusculary. Clinical findings, electrocardiograms and some blood chemical values were determined and the results obtained were as follows: 1. After administration of 5 mg/kg dose of combelen the animals were moderately depressed and often tried to take sitting position but showed moderate response to pinching stimulation of skin. 2. Body temperature and respiratory rate were not suppressed but heart rate were accelerated during sedative stage. 3. During sedation a slight change in the QRS complex and T wave appeared but it was not significant. 4. Hemoglobin concentration showed a tendency to decrease. SGOT activities were markedly increased 24 hours after administration of combelen and BUN values were slightly lowered. Blood sugar values were markedly elevated during sedative stage.

Investigations for hematologic and biochemical values for Gyeongju DongGyeong dogs were performed. This study were conducted to determine normal blood and serum chemical values on DongGyeong dogs. Normal blood and serum chemical values were studied in 47 healthy dogs (male 28, female 19). The hematologic and serum chemistry results were confirmed by age, sex, shape of tail. The hematological values showed no difference from Korea native dogs. The hematocrit values ($49.0{\pm}8.1$(%)) of DongGyeong dogs (2-3 years group) were significantly higher than other dogs. The mean levels of MCV ($61.6{\pm}3.8({\mu}m^3)$) in DongGyeong dogs were lower than general dogs. The levels of cholesterol($220{\pm}80.5$(mg/dl)) and inorganic phosphorus ($3.6{\pm}1.0$ (mg/dl)) of DongGyeong dogs (2~3 years group) were significantly higher than Korea native dogs. Totally concentration of triglyceride ($66.2{\pm}17.0$ (mg/dl)) of DongGyeong dogs were significantly lower than Korea native dogs. The mean values of BUN were increased with age but no significantly. In conclusion, data obtained from this study may be valuable as a standard for interpretation of the results in hematologic and biochemical analysis of Gyeongju DongGyeong dog populations.

Purpose: We evaluated three blood glucose self-monitoring for measuring whole blood glucose levels in preterm and low-birth-weight infants. Methods: Between December 1, 2012 and March 31, 2013, 230 blood samples were collected from 50 newborns, who weighed, ${\leq}2,300g$ or were ${\leq}36$ weeks old, in the the neonatal intensive care unit of Eulji University Hospital. Three blood glucose self-monitoring (A: Precision Pcx, Abbott; B: One-Touch Verio, Johnson & Johnson; C: LifeScan SureStep Flexx, Johnson & Johnson) were used for the blood glucose measurements. The results were compared to those obtained using laboratory equipment (D: Advia chemical analyzer, Siemens Healthcare Diagnostics Inc.). Results: The correlation coefficients between laboratory equipment and the three blood glucose self-monitoring (A, B, and C) were found to be 0.888, 0.884, and 0.900, respectively. For glucose levels ${\leq}60mg/dL$, the correlation coefficients were 0.674, 0.687, and 0.679, respectively. For glucose levels>60 mg/dL, the correlation coefficients were 0.822, 0.819, and 0.839, respectively. All correlation coefficients were statistically significant. And the values from the blood glucose self-monitoring were not significantly different from the value of the laboratory equipment, after correcting for each device's average value (P>0.05). When using laboratory equipment (blood glucose ${\leq}60mg/dL$), each device had a sensitivity of 0.458, 0.604, and 0.688 and a specificity of 0.995, 0.989, and 0.989, respectively. Conclusion: Significant difference is not found between three blood glucose self-monitoring and laboratory equipment. But correlation between the measured values from blood glucose self-monitoring and laboratory equipment is lower in preterm or low-birth-weight infants than adults.

Present study was undertaken in order to find out the most significant laboratory test for the early diagnosis of ethylene glycol poisoning in dogs. Seven dogs weighing from 5.0kg to 19.3kg were administered orally 6ml or l0ml of ethylene glycol per kilogram of body weight. In addition to clinical observations, blood samples were taken from the jugular vein on 0, 1, 3, 6, 12, 24 and 48 hours or until death after the adminisration and examined for the hematological, blood chemical, venous blood gas and electrolyte changes. Urine samples were simultaneously taken and examined for pH, protein, glucose and calcium oxalate crystals in the sediments. The results were as follows : 1. All dogs showed marked hypothermia in addition to the characteristic signs of ethylene glycol poisoning until death. 2. No significant hematological changes were observable after the administration of ethylene glycol except the secondary dehydration and stress leukogram. 3. Chemical values related to the liver function(serum glutamic pyruvic transaminase, total serum protein, serum albumin, serum total bilirubin) showed no significant changes during the experimental period in all dogs. 4. Chemical values related to the renal function(BUN and creatinine) showed significant(p<0.0l, p<0.001) increase from 24 hours to death in all dogs. 5. All dogs showed significant(p<0.01, p<0.001) decrease in blood pH from 3 hours to death after the ethylene glycol administration. 6. All dogs showed significant(p<0.05, p<0.01, p<0.001) increaes in anion gap from 1 hour to death after the ethylene glycol administration. 7. All dogs showed significant(p<0.05, p<0.01) decrease in urine pH from 1 hour to 6 hours after the administration of ethylene glycol. 8. Characteristic envelope form of calcium oxalate crystals were found in the urinary sediment from 6 hours after the administration of ethylene glycol in all dogs. 9. Histologically calcium oxalate crystals were found in the renal rubles in all dogs. 10. From these results, it may be concluded that the examinations of urinary sediments for the calcium oxalate crystals, blood or urinary pH and blood anion gap are most reliable tests for the early diagnosis of ethylene glycol poisoning in dogs.

Blood chemistry values according to ages have rarely been investigated in indigenous Korean calves. The present study aimed to clarify the changes in blood chemistry values of indigenous Korean calves with age. Blood samples were collected from 29 calves (11 females and 18 males) reared at the Gyeongsangbukdo Livestock Research Institute and the levels of various chemical components in the serum were analyzed. The total protein, albumin and globulin concentration in the calves increased gradually over time. The glucose concentration increased significantly at 2 weeks after birth, and then decreased slightly 4 weeks after birth. The blood urea nitrogen concentration increased from 2 weeks after birth, and the levels in females were higher than those in males at 2 and 4 weeks after birth. The creatinine concentration decreased significantly from 2 weeks after birth, and the levels in females were higher than those in males at 2 weeks and 6 months after birth. The total bilirubin concentration decreased gradually from 2 weeks after birth. The glutamic oxaloacetic transaminase and glutamic pyruvic transaminase concentration increased gradually from 2 weeks after birth. The triglyceride concentration tended to increase from 2 weeks after birth. The total cholesterol concentration increased significantly at 2 weeks after birth, and then decreased slightly 4 weeks after birth. The total high density lipoprotein cholesterol concentration increased significantly from 2 weeks after birth. The calcium concentration was maintained between $9.8{\pm}0.8mg/dL$ and $11.6{\pm}0.9mg/dL$ throughout the investigation period, although some levels fluctuated at 4 weeks and 6 months after birth. The phosphorus concentration increased significantly at 2 weeks after birth, and then decreased slightly 4 weeks after birth. In conclusion, the data obtained from this study may be valuable for use as a standard for interpreting results of blood biochemical analyses in indigenous Korean calves.
