  • The encapsulation of the Purified bovine hemoglobin with Phospholipids obtained from egg folk was performed using a rotary vacuum evaporator. The prepared Hb-containing liposome (hemosome) had good properties as artificial red blood cell. The shape and size of the hemosomes were measured by a phase contrast microscope and image analyzer. The function of the hemosome as oxygen carrier was tested by measuring oxygen saturation curve with blood gas analyzer and infusing it into rats. The prepared hemosome was 1.184 + 0.423 ${\mu}m$ in diameter and round in shape. $P_{50}$ value of the hemosome solution was 28 mmHg. The synthesized red cells seem to function as oxygen carrier, because the severely bled rats were prolonged in their life by transfusion of the hemosome solution containing bovine hemoglobin.

  • The hemoglobin phenotype and the gene frequencies of 44 Formosan deer(Cervus nippon) in Kyung-Gi area were examined by using cellulose acetate and starch gel electrophoresis. 1. The method of cellulose acetate electrophoresis was simplier, more clear and preserative than starch gel electrophoresis. 2. The hemoglobin phenotype was appeared 3 types as $Hb^F$ $Hb^{FS}$ and $Hb^S$. The frequencies of appearance were $Hb^F$ 47.7%, $Hb^{FS}$ 47.7% and $Hb^S$ 4.5%, respectively. 3. The genetic factors of hemoglobin were observed as $Hb^F$ and $Hb^S$ and the rates of gene frequencies were 71.6% and 28.4%, respectively.

  • Adiponectin is secreted specifically by adipose tissue and regulates lipid and glucose metabolism. In addition, adiponectin has been found to inhibit inflammatory process and possibly atherogenesis. This study was done to compare hematological parameters, serum lipids with serum adiponectin level according to body mass index (BMI) and gender in eighty eight Korean adults aged 40 to 68. In this study, the association between serum adiponectin and other variables including RBC counts, hemoglobin, hematocrit and albumin were investigated. RBC, hemoglobin status, was inversely associated with serum adiponectin levels in normal adult women. Adiponectin levels were significantly lower in men than women (p<0.01). In men, serum adiponectin levels were negatively correlated with body mass index (BMI) (p<0.05). However, no correlations were found in women. These results might imply that the regulation of key adipokines such as adiponectin might be a strategy for the prevention or treatment of obesity-associated diseases.

  • To elucidate the effect of gamma-irradiation on the molecular properties of hemoglobin, the secondary, tertiary structure, and the molecular weight size of the protein were examined after irradiation at 0.5, 1, 5, and 10 kGy. Gamma-irradiation of hemoglobin solutions caused the disruption of the ordered structure of the protein molecules, as well as degradation, cross-linking, and aggregation of the polypeptide chains. A SDS-PAGE study indicated that irradiation caused initial fragmentation of the proteins and subsequent aggregation due to cross-linking of the protein molecules. The effect of irradiation on the protein was more significant at lower protein concentrations. Ascorbic acid decreased the degradation and aggregation of proteins by scavenging oxygen radicals that were produced by irradiation. A circular dichroism study showed that irradiation decreased the helical content of hemoglobin with a concurrent increase of the aperiodic structure content. Fluorescence spectroscopy indicated that irradiation decreased the emission intensity that was excited at 280 nm.

  • Noninvasive monitoring of total Hemoglobin value is feasible with the use of spectroscopic measurements. As a step toward tile final goal of the development of a noninvasive monitor, the spectra$(400{\sim}800mm)$of EDTA whole blood were obtained along with reference total Hemoglobin values. Under the same condition water spectrum was generated. It was subtracted from each blood sample, and then tile first derivative of each subtracted data was taken by 'approximated first derivative algorithm' with gap (1,6,10,20nm). The correlation was obtained between total Hemoglobin and first valley wavelength of first derivative spectrum (sample number: 93).

  • Genetic variation of hemoglobin and erythrocyte ganglisoside monooxygenase were analyzed in Korean nature dog Sapsarees by horizontal starch gel electrophoresis and thin layer chromatography. Hemoglobin has three phenotypes A, B and AB, which are controlled by two codominant alleles, {TEX}$Hb^{a}${/TEX} and {TEX}$Hb^[b}${/TEX}, at one autosomal locus. Gene frequencies of {TEX}$Hb^{a}${/TEX} and {TEX}$Hb^{b}${/TEX} were 0.537 and 0.4625. Ganglioside monooxygenase has two phenotypes, dominant and recessive. They are controlled by a dominant allele {TEX}$Gmo^{a}${/TEX} and a recessive allele {TEX}$Gmo^{g}${/TEX}. Frequencies of {TEX}$Gmo^{a}${/TEX} and {TEX}$Gmo^{g}${/TEX} were 0.5477 and 0.4523.

  • Using recombinant DNA technology, the vector system containing minimal fragment of a bacterial hemoglobin gene (vgb) was constructed. When this vector was inserted into Escherichia coli, the growth of the host was significantly improved in both viable cell counts and absorbance measurement, compared to that of the wild type strain. In addition, by minimizing the size of bacterial hemoglobin in the vector, the ability of vgb in growth improvement was augmented, due to the reduction of metabolic burden from the maintenance and replication of the plasmid. By using this system, it is expected that the growth of microorganisms can be improved even in the hypoxic condition.

  • The study was conducted to investigate the phenotypes of blood proteins, hemoglobin and albumin, of 104 German shepherds in Dag-gu, Yae-chum Kim-hae and Kwang-ju area by the starch gel electrophoresis. The results obtained were summarized as follows: 1. The hemoglobin phenotypes were observed three(HbBB, HbBb and Hbbb). Fast migrating bands were same and slow migrating bands were divided by heavy(HbBB), light(HbBb) and non-stained(Hbbb). The frequencies of appearance in HbBB, HbBb and Hbbb were 17.31%, 51.92% and 30.77%, respectively. 2. The hemoglobin phenotypes were controlled by two allelic genes, $Hb^b$ and $Hb^B$. The gene frequencies were calculated at 0.567 in $Hb^B$ and 0.433 in $Hb^A$. 3. The albumin phenotypes were observed three(AlbFF, AlbSS and and AlbFS), which were divided by fast migrating band(AlbFF), slow migrating band(AlbSS) and mixed migrating band(AlbFS). The frequencies of appearance in AlbFF, AlbFS and AlbSS were 5.77%, 28.85% and 65.38%, respectively. 4. The albumin phenotypes were controlled by two alleic genes, $Alb^F$ and $Alb^S$. The gene frequencies were calculated at 0.202 in $Alb^F$ and 0.798 in $Alb^S$.

  • The hydrolysis of proteins constitutes an invaluable tool, granting access to a variety of peptide fragments with potentially interesting biological properties. Therefore, a hemoglobin (Hb) hydrolysate of Crocodylus siamensis was generated by digestion under acidic conditions. The antibacterial and antioxidant activities of the Hb hydrolysate were assessed in comparison with intact Hb. A disc diffusion assay revealed that the Hb hydrolysate exhibited antibacterial activity against eight strains of gram-positive bacteria and showed a higher efficacy than intact Hb. Moreover, the antioxidant activity of intact Hb and its hydrolysate was evaluated using ABTS and DPPH radical scavenging assays. The Hb hydrolysate exhibited free radical scavenging rates of 6-32%, whereas intact Hb showed a slightly higher activity. In addition, non-toxicity to human erythrocytes was observed after treatment with quantities of Hb hydrolysate up to $10{\mu}g$. Moreover, active fragmented Hb (P3) was obtained after purifying the Hb hydrolysate by reversed-phase HPLC. Scanning electron microscopy demonstrated the induction of bacterial cell membrane abnormalities after exposure to P3. Antibacterial and antioxidant activities play crucial roles for supporting the wound healing activity. Consequently, an in vivo mice excisional skin wound healing assay was carried out to investigate the effects of intact Hb treatment on wound healing in more detail. The results clearly demonstrate that intact Hb is capable of promoting 75% wound closure within 6 days. These findings imply that intact Hb of C. siamensis and its acid hydrolysate may serve as valuable precursors for food supplementary products benefitting human health.
