  • To estimate the source of variance components for some hematological parameters and assess the utility of the conventional population-based reference interval, this study computed index of individuality for blood samples, which were from 13 dogs drawn once weekly for 4 consecutive weeks. Results were subjected to nested analysis of variance. For all parameters measured between-dog variations were greater than within-dog variation. Except for the parameters RBC and MCHC the index of individuality was <1.4. The low reliability coefficient and high index of individuality of ${\leq}0.8$ were found for the majority of hematological parameters. In practical term, the present study indicated that use of hemogram profiles alone in the evaluating clinical state of a single patient should be avoided because of their physiological or natural random variations, and that comparing a single measurement on the blood analytes from an individual dog to the conventional population-based reference range may be too insensitive to detect any significant changes in the blood components of that particular dog. A single measurement may not characterize an individual's average concentration of the parameters even shortterm period.

  • We studied the effects of intake of the steamed bean powder(SB) and chungkukjang powder(CK) on blood parameters such as glucose, albumin, GOT, GPT, hematocrit, hemoglobin, total-/HDL-/LDL-cholesterol and triglyceride, and blood antioxidant nutrients such as retinol, tocopherols and carotenes in 26 college women. There were 2 groups, one group had 13 participants who consumed 30g SP and second group (13 participants) consumed 30g CK daily for 4 weeks. The study compared before with after SP/CK intake. The average age of the participants was 22.1 years, there were no significant differences between the two groups in terms of all parameters before the study. The energy intake showed no significant differences between before and after SP/CK intake. C(carbohydrate) propotion was reduced, and P(protein) and F(fat) ratio were increased after 4 week intake of SP/CK. Indices of nutritional quality(INQ) of protein(p<0.01), iron(p<0.05), zinc(p<0.05), vitamin C(p<0.05) were significantly increased after SP intake, and those of protein(p<0.05) and zinc also increased after CK intake. There were no significant differences in TG, total-/HDL-/LDL-cholesterol before and after SP/CK intake. The CK intake group showed the reduction only in retinol level in blood(p<0.05). Some students reported the improvement of the constipation and the regularity of the bowel elemination, and some students experienced the prolongation effects on one's monthly days after SP/CK intake. In this study, we could see the effect of improvement in some nutrients intake, but no effect in blood parameters by SP/CK intake for 4 weeks. That reason might be that the participants were healthy young women, or the trail period was not enough long to change.

  • The effects of different dietary electrolyte balance (DEB) on growth performance, nitrogen (N) metabolism and some blood biochemical parameters were investigated in 2 to 3 months old growing rabbits. A total of 150 growing rabbits of 2 months age were randomly divided into five groups according to average body weight, with 30 rabbits in each group. The DEB levels of the five experimental diets were -154, -3.16, +201, +347, and +500 meq/kg of dry matter (DM), respectively. There was a 7-d adaptation period and a 23-d experimental period. The results showed that the DEB levels had a quadratic affect on the average daily feed intake (ADFI) (p<0.001). The greatest ADFI was achieved when the DEB level was +201 meq/kg DM. Fecal N (FN) content linearly decreased (0.047), while digestible N (DN), retained N (RN), efficiency of intake N converted into digestible N (DN/IN) and the efficiency of intake N converted into retained N (RN/IN) linearly increased with the DEB increase (0.020, 0.004, 0.021, and 0.049, respectively). Serum phosphorus (P) ion content linearly increased with the DEB increase (p = 0.036). The DEB had a quadratic relationship with serum anion gap (AG) (p = 0.002) and serum parathyroid hormone (PTH) content (p = 0.016). The DEB levels quadratically affected base excess (BE) in the plasma (p<0.001). In conclusion, the DEB unaffected growth performance but affected feed intake, N metabolism and some blood biochemical parameters of growing rabbits.

  • Abnormal hematological values are associated with various disorders including cancer and cardiovascular, metabolic, infectious, and immune diseases. We report the copy number variations (CNVs) in clinically relevant hematological parameters, including hemoglobin level, red and white blood cell counts, platelet counts, and red blood cell (RBC) volume. We describe CNVs in several loci associated with these hematological parameters in 8,842 samples from Korean population-based studies. The data that we evaluated included four RBC parameters, one platelet parameter, and one associated with total white blood cell (WBC) count, exceeding the genome-wide significance. We show that CNVs in hematological parameters are associated with some loci, different from previously associated loci reported in single nucleotide polymorphism (SNP) association studies.

  • Controlling dietary behaviors and health-related lifestyle habits is important to manage non-insulin dependent diabetes mellitus (NIDDM). If NIDDM is not treated properly, the prevalence of macro-vascular complications (MC) may increase. The goal of NIDDM therapy is to maintain normal concentrations of blood glucose and lipid profiles by having regular meals, controlling alcohol drinking, quitting smoking, and performing physical exercise regularly. This study was performed to investigate the dietary and health-related lifestyle habits and blood parameters of NIDDM patients of both genders and compared these characteristics between the patients with and without MC. Our results show that the subjects with MC compared to without MC and the female patients than the males controlled their diets more regularly, tended to regulate the number of meals better, and smoke less than those without MC. Although plasma lipid profiles were not significantly different between the genders and between the subjects with and without MC, the men had higher blood glucose and plasma tHcy concentrations than the women and plasma tHcy concentration was higher in the female subjects without MC. These results imply that the male patients of NIDDM without MC might have more problems in maintaining their blood glucose. In addition, smoking may be the most important life-style factor influencing some blood parameters like blood glucose, HbAlc, and total cholesterol in the NIDDM patients.

  • This study was conducted to determine the nutritive value of live yeast culture (RumiSacc, Saccharomyces cerevisiae) and to investigate its effects on milk yield, milk composition and some blood parameters in lactating cows. Six multiparous Holstein cows were allocated to two groups of three cows and assigned randomly to one of two diets in a cross-over experiment. Daily 50 g RumiSacc was top dressed at the p.m. feeding for the treatment group. RumiSacc supplied a high protein and energy with high organic matter digestibility values (83.35%) determined by in vitro enzymatic analysis. Yeast culture supplementation significantly increased milk yield, tended to increase fat yield, protein yield and lactose yield of milk. Methylated fatty acid level of 18:3 (n-3) in milk fat was increased by yeast culture supplementation. The concentrations of methionine, phenyalanine, tyrosine, tryptophan and taurine were significantly increased with dietary inclusion of yeast culture. Live yeast culture supplementation did not affect other performance characteristics, milk quality characteristics and blood parameters. As a conclusion live yeast culture (RumiSacc, Saccharomyces cerevisiae) had high nutritive value and positive effects on milk production and some milk quality characteristics in lactating cows under field conditions.

  • The desirable method to diagnose abnormal blood pressure is to measure and manage blood pressure continuously and regularly. However, the sphygmomanometers that are based on a cuff have faults in that they can not measure the blood pressure continuously and they cause an unpleasant feeling. Therefore, it is essential to develop a new measuring method that causes no pain and that can obtain blood pressure continuously without any unpleasant feeling. Thus, we propose here a regression method to estimate the systolic blood pressure by using the PTTL(pulse transit time on leg) with some body parameters which are chosen from the relational analysis with systolic blood pressure. The data we use to make the regression model were obtained in triplicate from each of 50 males who were from 18 to 35 years. And we made estimation experiments of blood pressure on 10 males who did not take part in the making the regression model. According to the results, the proposed method showed a mean error of 4.00 mmHg and the standard variance was 2.45 mmHg. When we comparing the results of the proposed method with the rule of American National Standards Institute of the Association of the Advancement of Medical Instruments(ANSI/AAMI), the results satisfied the rule of a mean error less than 5 mmHg and a standard variance less than 8 mmHg. Therefore we were able to validate the usefulness of the proposed method.

  • To elucidate the relationship between blood parameters related bone metabolism and antioxidant enzyme activity in postmenopausal period 60 women residing in Iksan area were recruited. Food and nutrient intake of each individual subject were estimated by 24-hour recalls of 3 non-consecutive days. The biochemical markers including total protein, albumin, osteocalcin (intact bone gla protein; BOP), calcium, phosphorus and hemoglobin were measured in fasting blood. In addition, parameters of antioxidative capacity including the activities of superoxide dismutase (SOD), glutathione peroxidase (GPx) , catalase (CAT) and total antioxidant capacity (TA) were monitored in blood, also. The mean age, height, weight, and BM! of subjects were 64.8 years, 151.1 em, 59.5 kg $26.0\;kg/m^2$, respectively. The mean SOD, GPx, and CAT activities were 138.5 U/ml, 1,273.8 U/ml and 314.3 kU/l respectively, and TA was 1.16 mmol/l without significant difference among different age groups. BMI was positively correlated with SOD activity (p < 0.01). SOD activity and CAT activity showed positive correlation with serum albumin (p < 0.05) and hemoglobin (p < 0.01). In conclusion, this study revealed that antioxidant enzyme activity holds a significant relationship with the blood parameters like as serum albumin and hemoglobin in postmenopausal women and further systematic research is needed to investigate the their relation mechanism.

  • Three hundred and twelve female Tsaiya ducks from four lines (L1051, L1052, L1053 and L1054) were used in this study to investigate the changes in plasma calcium and inorganic phosphorus levels, blood pH, carbon dioxide partial pressure (pCO$_{2}$), bicarbonate ion concentration ($HCO_{3}^{-}$), and base excess (BE) during laying periods. The results indicated that plasma calcium and inorganic phosphorus concentration at 40 and 50 wks of age were higher (p<0.05) than those at other ages. Significant positive correlation coefficients were found between plasma calcium and inorganic phosphorus levels at each age tested from 20 to 50 wks. Ducks from L1053 showed lower (p<0.05) blood pH, BE and $HCO_{3}^{-}$ as compared with other lines. Ducks from L1054 had higher (p<0.05) blood pH, BE and $HCO_{3}^{-}$ than those of other lines showing that there were some differences on blood parameters among lines. Eggshell strength decreased with age up to 65 wks and remained constant thereafter. Egg weight increased gradually from 30 to 60 wks and decreased slightly after 70 wks of age. Plasma inorganic phosphorus level in 40 and 50 wks old birds was positively correlated with eggshell strength, while blood $HCO_{3}^{-}$ in 40 and 50 wks old birds was negatively correlated with eggshell strength.

  • Invasive blood pressure (IBP) is measured for the patient's real time arterial pressure (ABP) to monitor the critical abrupt disorders of the cardiovascular system. It can be used for the estimation of cardiac output and the opening and closing time detection of the aortic valve. Although the unexplained inflections on ABP make it difficult to find the mathematical relations with other cardiovascular parameters, the estimations based on ABP for other data have been accepted as useful methods as they had been verified with the statistical results among vast patient data. Previous windkessel models were composed with systemic resistance and vascular compliance and they were successful at explaining the average systolic and diastolic values of ABP simply. Although it is well-known that the blood pressure reflection from peripheral arteries causes complex inflection on ABP, previous models do not contain any elements of the reflections because of the complexity of peripheral arteries' shapes. In this study, to simulate a reflection wave of blood pressure, a new mathematical model was designed with four elements that were the impedance of aorta, the compliance of aortic arch, the peripheral resistance, and the compliance of peripheral arteries. The parameters of the new model were adjusted to have three types of arterial blood pressure waveform that were measured from a patient. It was used to find the relations between the inflections and other cardiovascular parameters such as the opening-closing time of aortic valve and the cardiac output. It showed that the blood pressure reflection can bring wide range errors to the closing time of aortic valve and cardiac output with the conventional estimation based on ABP and that the changes of one-stroke volumes can be easily detected with previous estimation while the changes of heart rate can bring some error caused by unexpected reflections.
