  • 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.

  • The change of rouleau formation of red blood cells in the hand stimulated by pulse magnetic field having a maximum intensity of 0.27 Tesla and pulse duration of 0.102 msec was investigated. Before pulse magnetic field stimulus, the red blood cells of test subject were adjoined over ten and the flow of cells was slowed. However after the stimulus in the hand during 10 minutes, the red blood cells adjoined over tens was spreaded out each other and its motion was fast. Also the red blood cells of left hand unstimulated by pulse magnetic field were spreaded out each other, even though the right hand was stimulated during 10 minute. It prove that the rouleau formation of red blood cells can be improve in the whole body in spite of stimulus in the hand because the blood is flowing a whole body.

  • The present study aimed to investigate the effect of whole wheat cookie supplemented with Capsosiphon fulvescens (CF) extract on serum glucose homeostasis in C57BL/6 mice. This study examined whether the same effect was demonstrated for whole wheat cookie in comparison to previous research documenting the glucose-lowering effect of food products combined with CF extract. Mice were divided into three groups depending on the diet administered: normal cookie (NC), whole wheat cookie (WC), and WC blended with CF extract (WCFE). After 4 weeks of administering the experimental diet, the blood glucose level, serum insulin level, and homeostatic model assessment for insulin resistance index were found to be significantly lower in the WCFE group than in the NC and WC groups. These results suggest that whole wheat cookie containing CF extract is effective in preventing insulin resistance and maintaining blood glucose homeostasis.

  • Thirty two Holstein female calves (initial body weight = $40{\pm}3.0$ kg) were used to investigate the effects of probiotic and prebiotic on average daily gain (ADG), fecal E. coli count, white blood cell count, plasma IgG1 level and cell-mediated immune response to injection of phytohemagglutinin in suckling female calves. Calves were assigned randomly to one of the four treatments, including whole milk without additives (control), whole milk containing probiotic, whole milk containing prebiotic and whole milk containing probiotic and prebiotic (synbiotic). Average daily gain was greater in calves fed probiotic, prebiotic and synbiotic at weeks 6, 7 and 8 (p<0.05). E. coli count was significantly lower in calves fed probiotic, prebiotic and synbiotic on d 56 (p<0.05). There was no significant difference between treatments in blood samples and cell-mediated response. This study showed that addition of probiotic, prebiotic and combination of these additives to milk enhanced ADG and reduced fecal E. coli count in preruminant calves.

  • This study was conducted to determine effects of different selenium (Se) sources on performance, carcass characteristics, blood measures (whole blood Se concentration and plasma glutathione peroxidase (GSH-Px) activity), and Se concentrations in tissues of finishing Hanwoo steers (Korean native steers). Twenty finishing Hanwoo steers (average body weight=536${\pm}$23.4 kg, average age=approximately 20 months) were allotted to treatments in four groups of five steers per pen for 16 weeks preceding slaughter. Treatments were control (CON), spent mushroom composts from Se-enriched mushrooms (Se-SMC), selenized yeast (Se-Y), and sodium selenite (SS). Dietary Se levels of all treatments except CON were 0.9 mg Se/kg on the dry matter basis. Body weight was measured at the first and final day of trial, and blood samples were collected to analyze whole blood Se concentration and plasma GSH-Px activity at 2, 4, 8, and 16 weeks. At the end of trial, steers were slaughtered to collect muscle and liver samples for their Se analyses, and carcass data were recorded. In terms of dry matter intake, body weight gain and carcass characteristics, no significant differences among treatments were observed. Whole blood Se concentrations were significantly higher (p<0.05) for Se-SMC and Se-Y treatments than for CON at each collection period, with no significant difference between SS and CON. For weeks 2 and 8, there was no significant difference for whole blood Se concentration between Se-SMC and Se-Y, but for weeks 4 and 16, Se-Y treatments were significantly higher (p<0.05) than Se-SMC. No differences were observed for plasma GSH-Px activity between Se-SMC and Se-Y. The Se concentrations in hind leg and liver were significantly different among treatments (p<0.05) and those in both tissues ranked the greatest in Se-Y, followed by Se-SMC, SS, and CON treatments. However, tissue Se concentration for SS was not different from that for CON. These results showed that feeding organic Se sources such as Se-SMC and Se-Y enhanced Se concentration in tissues, while SS, the most common supplement of inorganic Se, was inefficient in Se deposition. Even though Se-Y had a higher Se concentration in tissues than Se-SMC, replacing Se-Y with Se-SMC in diets of beef steers would be an inexpensive way to increase Se concentration in beef.

  • In this paper a newly designed oxygenator module was used to perform the experiments for pressure drop and oxygen transport in order to evaluate the efficiency of the artificial lung. Also, distilled water. sodium sulfite solutions used in this experiment were evaluated for the performance of other artificial lungs. Substituted bloods have many advantages over whole blood in studying pressure drop and oxygen uptake. They are relatively inexpensive, and require fewer variables to be controlled. Furthermore, deoxygenation is not necessary when those solutions are used. In addition to these advantages. assays and interpretation of the experimental results are relatively easy. In the case of using the sodium sulfite solution having the same oxygen partial pressure as whole blood. the oxygen transfer rate of the sodium sulfite solution was basically same as that of whole blood. It was concluded in evaluating the function of artificial lungs that the sodium sulfite solution was suited for measuring oxygen transfer rate. In our module, artificial blood was flowed into the outside of hollow fiber membrane. The artificial lung created in this experiment showed that pressure drop was reduced to $1/3\~1/6$ of that compared to the inside-flow case.
