  • Cell separation from peripheral blood was investigated using surface-modified polyurethane (PU) membranes with different functional groups. Both red blood cells and platelets could pass through unmodified PU and PU-SO$_3$H membranes, while the red blood cells preferentially passed through PU-N(C$_2$H$_{5}$ )$_2$ and PU-NHC$_2$H$_4$OH membranes. The permeation ratio of T and B cells was less than 25% for the surface-modified and unmodified PU membranes. CD34$^{+}$ cells have been recognized as various kinds of stem cells including hematopoietic and mesenchymal stem cells. The adhesiveness of CD34$^{+}$ cells on the PU membranes was found to be higher than that of red blood cells, platelets, T cells or B cells. Overall, the adhesiveness of blood cells on the PU membranes increased in the following order: red blood cells $\leq$ platelets < T cells $\leq$ B cells < CD34$^{+}$ cells. Treatment of PU-COOH membranes with a human albumin solution to detach adhered blood cells, allowed recovery of mainly CD34$^{+}$ cells in the permeate, while both red blood cells and platelets could be isolated in the permeate using unmodified PU membranes. The PU membranes showed different permeation and recovery ratios of specific cells depending on the functional groups attached to the membranes.mbranes.

  • In order to study the effects of Aloe vera treatment on blood glucose level and clinical chemistry in diabetic patients, eight diabetic patients were administered orally with 800 mg of Aloe vera three time a day for three months. The high levels of blood and urine glucose in diabetic patients were significantly reduced by administration of Aloe vera. The increased plasma triglyceride concentration was also significantly reduced by Aloe vera treatment. A little amount of urine bilirubin, hematuria, nitrite, urobilinogen, protein and ketone bodies were detected before treatment, but not detected after Aloe vera treatment. But other blood parameters of clinical chemistry values were not affected by Aloe vera treatment. These data suggest that Aloe vera can be effective in the treatment of the diabetic patients.

  • Starvation, diabetes, alcoholism and hypothermia cause ketoacidosis in the human body; therefore, the cause of death can be determined by analyzing ketone bodies in the blood of the deceased. In the case of decomposition of the cadaver, however, since collecting intact blood is impossible, ketone body analysis is performed using the spleen. However, the index for diagnosing ketoacidosis is based on blood concentration, and its correlation with ketone bodies present in the spleen remains unknown. In particular, since decomposition proceeds rapidly during summer, when temperature and humidity are high, understanding the correlation between ketone bodies in the blood and spleen is important to estimate the state at the time of death from a decaying body. Therefore, in the present study, the correlation between ketone bodies in the blood and spleen of the deceased was explored. Ketone bodies (beta-hydroxybutyric acid [BHB] and acetone) in the blood and spleen were analyzed and compared from autopsies (>100 mg·L-1 BHB, blood basis) conducted at the Daejeon Forensic Research Institute from June to December 2021. Moreover, the concentration of ketone bodies in the spleen juice and tissues was compared assuming the scenario of extreme decomposition. Ketone retention concentration in the blood and spleen was positively correlated, and the ratio of BHB concentration in the spleen to BHB concentration in the blood ranged from 0.52 to 1.08 (mean = 0.85 ± 0.12), although the ratio may vary depending on the degree of decomposition of the corpse.

  • During the period from june 1994 to february 1995 influence of free stall with concrete floor on profile of blood chemistry and clinico-morphopathogenesis of foot disease on 266 cows were studied. The results obtained as follow. 1. No differences between value of blood chemistry in normal and lame cows with foot disease were observed. 2. 20.7% of the cows were clinically lame. 3. Prevalence of clinical digital disorders were investigated: hyperplasia interdigitalis(45.8%), pododermatitis circumscripta(22.4%), dermatitis interdigitalis(9.4%), erosio ungulae(5.9%), phlegmona interdigitalis(3.5%), pododermatitis septica traumatica(3.5%), dermatitis digitalis(2.4%), white line disease(2.4%), pododermatitis aseptica diffusa(2.4%), dermatitis verrucosa(1.2%), fissura ungulae(1.2%) 4. Most claw lesions were located on lateral hindclaws and interdigital space of hindclaws.

  • 갈화(Puerariae flos)추출물이 rat의 혈액, 뇌 및 간의 ethanol농도를 유의차있게 감소시켰다. 혈중 ethanol의 감소 효과는 ethanol을 투여한지 1시간 경과한 때에 대조군과 가장 많은 차이를 보였으며 열수 추출물이 80% ethanol 추출물보다 혈중 ethanol 농도를 더 크게 감소시킴이 관찰되었다. Ethanol 투여 10분 전에 갈화추출물 투여가 1시간 전 혹은 10분 후에 투여한 군에 비해서 ethanol 농도 저하에 더 효과적이었으며, 간과 뇌 조직에서도 ethanol의 농도가 저하되는 현상이 관찰되었다. 그러나 이 때 acetaldehyde는 검출되지 않았다. 혈중 ethanol 농도를 가장 효율적으로 감소시키는 갈화 추출물의 적정량은 55.7 mg/kg body weight이었다. 이번 실험을 위해 새로이 시도된 dichloromethane에 의한 시료 추출과 GC를 이용한 분석법은 간단, 신속 하면서도 좋은 분석결과를 보였다.

  • The cord blood serves as a vehicle for the transportation of oxygen and nutrients to the fetus. In the past, the human cord blood has generally been discarded after birth. However, numerous studies have described the regenerative ability of the cord blood cells in various incurable diseases. The umbilical cord blood (UCB)-derived stem cells are obtained through non-invasive methods that are not harmful to both the mother and the fetus. Furthermore, the cord blood stem cells are more immature than the adult stem cells and expand readily in vitro. The mesenchymal stem cells (MSCs) have the capacity to differentiate in vitro into various mesodermal (bone, cartilage, tendon, muscle, and adipose), endodermal (hepatocyte), and ectodermal (neurons) tissues. This review describes the immunological properties of the human UCB-MSCs to assess their potential usefulness in the allogeneic transplantation for the regenerative medicine.

  • Blood glue was prepared to reutilize porcine blood. Plasma proteins after lyophilization were treated by addition of wood flour, sodium hydroxide, sodium silicate, and hydrated lime to make blood glue with a suitable adhesivity. Characteristics of the prepared blood glue was monitored by measuring the viscosity with time, and the relationship between degree of hydrolysis of plasma proteins by addition of various amounts of sodium hydroxide and adhesivity was studied. To prevent the emission of formaldehyde during manufacturing of plywood by blood glue, the cross-linking reaction of plasma protein with formaldehyde was also examined. Fourier transform infrared, circular dichroism, and fluorescence spectroscopy study showed that blood plasma proteins react with formaldehyde, resulting in removal of formaldehyde by cross-linking reaction.

  • To develop better blood compatibility of commercial polyurethane(PU), PU surface was chemically modified wi th a hydrophobic perfluorocarhon or a hydrophilic polyethylene oxide(PEO) and/or sulfonated groups, respectively. The water contact angle of modified PUs varied from $110^{\circ}$ to $0^{\circ}$. All the modified PUs were more blood compatible than untreated PU. In particular, PEO-sulfonate grafted PUs showed a very enhanced antithrombogenicity due to the synergistic effect of PEO and $SO_3$ groups. Therefore more hydrophobic and hydrophilic PU surfaces are promising for improving the blood compatibility.

  • To determine the effects of anesthesia to clove oil on the secondary stress indices, changes in haematological and blood chemistry were monitored in healthy crucian carps (Carassius auratus). 24 fishes were divided into three groups, and blood was collected before anaesthesia (control group), immediately after anaesthesia at a concentration of 30 mg/l clove oil (anesthetized group), and 24 h after anaesthesia (recovered group). The anesthesia to clove oil significantly increased glucose in anaesthetized group, and constantly decreased lactate dehydrogenase in anaesthetized group and recovered group. However, clove oil had not effect on other biochemical indices. These results suggests that the anesthetic use of clove oil at a concentration of 30 mg/l does not cause irreversible damage in carp.
