  • This study was conducted in order to determine the effect of intraoperative hemoglobin changes on intraoperative neuromonitoring (IONM). This was a retrospective study that included 339 participants who underwent cerebrovascular surgery. We compared anesthetic agents, intraoperative hemoglobin, hematocrit, blood transfusion, and blood loss. We examined motor evoked potential and sensory evoked potential to patients. There were significant differences in hemoglobin changes, bleeding levels, transfusion, anesthesia time, and postoperative mobility disorders. Moreover, compared with patients who received transfusions, those who did not receive transfusion had a lower average hemoglobin level, as well as a higher bleeding amount, and a need of higher anesthesia time and anesthetic dose. Also, we found vasospasm occurred while surgery can bring adverse results after operation. This study showed that an intraoperative decrease in hemoglobin levels affects the function of cerebral perfusion, which could result in abnormal nerve monitoring results. However, as this study could not find a relation of anesthetics to IONM, there is a need for further research regarding the association between anesthetics and hemoglobin changes and IONM.

  • This study has examined effects of protease on the removal of hemoglobin and triolein mixed soil with changes of soil content and soil composition from cotton and PET filament fabrics. The results obtained were as follows: The results obtained were as follows: 1) The detergency of PET fabrics was higher than that of cotton fabrics. The removal of hemoglobin was much higher than that of triolein from cotton fabrics, while the removal of hemoglobin was similar to that of triolein from PET fabrics. 2) The removal efficiency of hemoglobin and triolein was improved by protease from cotton and PET fabrics. Especially the removal efficiency of those was remarkably improved from cotton fabrics which the removal of soil was lower than PET fabrics. And the removal of hemoglobin and triolein by adding protease was increased with increase of hemoglobin content of mixed soil from cotton fabrics. 3) With the increase of hemoglobin content of mixed soil, the removal of hemoglobin was drastically increased but the removal of triolein was slightly decreased from cotton and PET fabrics. With the increase of triolein content of mixed soil, the removal of hemoglobin and triolein was decreased from cotton fabrics, but those were generally increased from PET fabrics.

  • To investigate the effects of strenuous physical exercise on commonly used hematological markers in subjects the intensive long running. Blood samples were obtained from nineteen participants in a 622 km ultra-marathon race before, 300 km and immediately after completion of the 622 km ultra-marathon. Samples were analyzed for total white cell count (WBC) and differential, total red cell count (RBC), hemoglobin, hematocrit, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), red cell distribution width (RDW), platelets, mean platelets volume (MPV), platelets distribution width (PDW). Significant increases were found in WBC, neutrophil and platelets at 622 km compared to the pre-race. RBC, hemoglobin and hematocrit decreased statistically significantly the race at 300 km and 622 km compared to pre-race. A wide range of hematological perturbations occur during 622 km ultra-marathon running but it was physiological changes within a reference range. The 622 km ultra-marathon is less likely to cause clinically significant hematologic changes in athletes.

  • Using continuous wave near-infrared spectroscopy, we measured time-resolved concentration changes of oxy-hemoglobin and deoxy-hemoglobin from the primary motor cortex following finger tapping tasks. These data were processed using partial least squares-discriminant analysis (PLS-DA) to develop a prediction model for a brain-computer interface. The tasks were composed of a series of finger tapping for 15 sec and relaxation for 45 sec. The location of the motor cortex was confirmed by the anti-phasic behavior of the oxy- and deoxy-hemoglobin changes. The results were compared with those obtained using the hidden Markov model (HMM) which has been known to produce the best prediction model. Our data imply that PLS-DA makes better judgments in determining the onset of the events than HMM.

  • Objectives : Anemia is the center of interest in every maternity, both during pregnancy and lactation. The oriental postpartum care has one principle : to invigorate Qi and blood greatly. In this study, we seek to confirm that most sufferers of anemia recover under oriental postpartum care. To assure that this study had significance in non-iron supplement, we made a comparative study between oral iron supplement and non-iron supplement groups in oriental postpartum care. Methods : A comparative study was conducted to discern the difference in hemoglobin change between admission and after 2 weeks under the circumstances of 30 oral iron supplemented and 38 non-iron supplemented women who were admitted to the hospital attached to Woosuk University Oriental Medical College from April to August 2001 for postpartum care. Results : The mean hemoglobin level of after 2 weeks was 11.95 mg% (p<0.001). The mean hemoglobin level after 2 weeks was 11.65 mg% and 12.18 mg% in the iron supplemented and non-iron supplemented women respectively. The difference between the two groups was not significant. Conclusions : Oriental postpartum care overcomes anemia significantly in postpartum maternity. This is confirmed significantly under the non-iron supplement.

  • The Korea chinese chives are a major edible vegetable and they are traditionally been used as a folk medicine. However recently studies on the Allium tuberosum are mainly on the morphological property and the chemical constituent. There are no reports concerning hematological changes in dogs administrated ethyl acetate extracts of Korea chinese chive. This experiment was conducted to investigate the hematological changes in dogs administrated ethyl acetate extracts of the Korea chinese chives($5m{\ell}/mg$) for 6 days. During administration blood samples were collected at 3h, 6h, 12h and then on daily basis until day 6. Blood samples were analyzed red blood cell(RBC), packed cell volume(PCV), hemoglobin concentration(Hb), mean corpuscular volume(MCV), mean corpuscularl hemoglobin concentration(MCHC), reduced glutathion(GSH), and met-hemoglobin concentration. The RBC count was significantly(p<0.01, p<0.05) decreased during experimental periods. Packed cell volume, hemoglobin concentration were not showed significantly difference during experimental periods. The MCV was significantly(p<0.01, p<0.05) increased from 3 hours after administration to day 4. The MCHC was significantly(p<0.05)decreased on day 6. GSH concentration was not showed significant difference during experimental periods and the met-hemoglobin concentration was significantly(p<0.05) increased on day 3.

  • The conformational dynamics of heme pocket, a small vacant site near the binding site of heme proteins -myoglobin (Mb) and hemoglobin (Hb), was investigated after photolysis of carbon monoxide from MbCO and HbCO in D$_2$O solution at 283 K by probing time-resolved vibrational spectra of photolyzed CO. Two absorption bands, arising from CO in the heme pocket, evolve nonexponentially in time. The band at higher energy side blue shifts and broadens with time and the one at lower energy side narrows significantly with a negligible shift. These spectral evolutions are induced by protein conformational changes following photolysis that modify structure and electric field of heme pocket, and ligand dynamics in it. The conformational changes affecting the spectrum of photolyzed CO in heme pocket likely modulates ligand-binding activity.

  • 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.

  • We investigated the fecal properties and hemoglobin levels in dogs fed with general canine diets and 7 black soldier fly-based companion canine diets. A total of 16 dogs, including 8 poodles (average weight 2.7±0.5 kg) and 8 bichon frises (average weight 2.0±0.5 kg) were used in this study. The changes in fecal properties of all treatments at 0 weeks and 2 weeks showed no significant differences (p>0.05). However, at 4 weeks, compared to the control group, all black soldier fly-based companion canine diets have an effect on fecal properties (p<0.05). Hemoglobin levels in all treatments were within the normal range. Therefore, feeding black soldier fly-based diets to canines affected the fecal properties and the hemoglobin level was not of clinical concern since it was within the desired reference intervals for healthy canines, indicating that the effect of iron supplementation and anemia prevention was not observed.
