  • Babesia gibsoni infection was diagnosed and treated in three hunting dogs which were hospitalized to the Veterinary Teaching Hospital, College of Veterinary Medicine, Seoul National University between April 4 and August 29, 1987. All three dogs revealed severe anemia, hemoglobinuria, splenomegaly and markedly decreased PCV, RBC count and hemoglobin. The anemia was regenerative, as characterized by increased numbers of nucleated erythrocytes, polychromasia, anisocytosis, reticulocytosis. B. gibsoni was identified by examination of blood smear stained with Giemsa stain. The forms of B. gibsoni identified in this report were pleomorphic such as singnet ring, oval, comma, dot and elongated forms. The maximal percentages of erythrocytes infected with one or more B. gibsoni organisms were 39%, 20% and 40%, respectively. The Tick, Haemophysalis longicornis was assumed to be the vector of babesiosis in these cases. Specific treatment consisted of diminazene aceturate and supportive treatment consisted of whole blood transfusion, lactated Ringer's solution, vitamin B complex and broad spectrum antibiotics. All three dogs had convalesced successfully after treatment.

  • The hemal nodes of the Korean native cattle were studied by gross anatomy and light microscopy. Hemal nodes were spherical or ovoid in shape, and red or black in colors. A hemal node consisted of a thick capsule and a hilum, and had extensive subcapsular and deep sinuses distended by a great number of erythrocytes. Although a few lymphatic nodules and tissues were seen in the parenchyma, no typical cortex and medulla was defined. Blood vessels occurred, but lymph vessel was not observed in nodes. The stroma of the hemal node was composed of reticular cells and fibers. The parenchyma consisted of many erythrocytes and lymphocytes, and a few macrophages and megakaryocytes. The capsule and trabecula was a collagenous connective tissue with smooth muscle cells. B-lymphocytes were principally located in the lymphatic nodules of the hemal node. T-lymphocytes were scattered in the diffuse lymphatic tissues of the hemal node.

  • The immunosuppressive effect of serum from mice heavily infected with BCG(BCG-serum) was evaluated. The delayed-type hypersensitivity reaction to sheep erythrocytes was depressed when BCG-serum was administered both systemically and locally at the same time of challenge. This study shows that serum of animal infected with mycobacteria contains a factor responsible for immunosuppression and factor may be important in understanding the mechanisms of allergy in mycobacteria] infections.

  • Twenty species of higher fungi growing in the wild were collected and studied extensively for their lectin activities by using erythrocytes of human, rabbit and mouse blood. In total, 14 species demonstrated hemagglutination with some kinds of erythrocytes. Of twenty species, eight (Boletus edulis, B. splendidus, Clavaria zollingeri, Lactaritis subzonarius, L. volemus, Russula cutefracta, Pholiota squarrosa, and P. aspera) were shown lymphoagglutination with murine splenic lymphocytes. Protein contents were estimated from the crude lectin fraction. Above mentioned eight species contained relatively high amounts of proteins than other mushrooms. Since these species had coincidently, hiig emagglutinating activity as well, we could define them as lectin-containeing mushrooms. Some species also contained mitogenic lectins toward murine splenic lymphocytes.

  • A lectin from the edible mushroom, Lentinus edodes, was purified through physiological saline extraction, ammonium sulfate fractionation and column chromatographies. On polyacrylamide gel electrophoresis, 0.05M fraction from hydroxyapatite column exhibited adjacent four sharp bands. The partially purified lectin agglutinated the erythrocytes of rabbit, mouse and rat, but not agglutinated human erythrocytes. The lectin's mitogenic effects were tested by its application to human and murine splenic lymphocytes. The results showed that the 0.05M fraction from hydroxyapatite was mitogenic, and the optimal dose of Lentinus edodes lectin was slightly lower than Con A by the culture with murine splenic and human peripheral lymphocytes. Meanwhile, its ability to agglutinate transformed cells was tested by its administration to continuous cell lines L1210 and HeLa cells. The leetin was found to be an agglutinin of tumor cell lines tested by L1210 and HeLa cells.

  • The present study was conducted to assess the dietary and nutritional status of thiamin in fourty-two elderly women. Dietary intake was determined by 24hour recall method and nutritional status of thiamin was determined by measurement of transketolase activity in erythrocytes. Average dietary intake of energy and thiamin were found to be low, and not more than 78% and 63.2% of Recommended dietary allowances(RDA) respectively. Transketolase activity in erythrocytes was distributed in the range of 0.227-0.589mU/mgHb and the mean value and 0.434mU/mgHb. The mean value of Thiamin pyrophosphate effect(TPP effect) was 24.0% and the range was from 9.36% to 83.9%. It appeared that 95% of 42 elderly women were severely or marginally deficient in thiamin status, showing 22 persons to be above 20% and 18 persons to be 15-20% of TPP effect. Transketolase activity and TPP effect did not show any significant correlation with dietary thiamin intake.

  • Our previous study demonstrated that aqueous ethanolic extract of hardy rubber tree (HRT; Eucommia ulmoides Oliver) leaves potently inhibited glycation, and that two known flavonols and one new flavonol were the active compounds in protein glycation in vitro using the model system of bovine serum albumin and fructose. The aim of this study was to examine the effectiveness of HRT extract and its flavonols against the glycation of hemoglobin (Hb) in primary cultured rat erythrocytes. The extract at $40-400\;{\mu}g/mL$ and the flavonols at $0.2-20\;{\mu}g/mL$ significantly inhibited Hb glycation in a concentration-dependent manner. They were more effective than aminoguanidine, a well-known inhibitor of glycation. Three flavonols seemed to be responsible for the inhibitory activity of the extract, furthermore, the extract of HRT leaves showed advantages over single isolated flavonols in the inhibition of Hb glycation.

  • The effect of oral iron supplementation was assessed on blood iron levels and Pb and Cd levels in erythrocytes, hair and urine of 101 Puchon 5th grade school children with suboptimal iron status. Treatment with 25mg of elemental iron per day for 8weeks resulted in a significant increase in the intake of most nutrients in addition to iron. Iron supplementation resulted in significant improvements in hemoglobin, MU, MCH, MCHC, serum ferritin, serum iron, TIBC, and transferrin saturation of subjects(p<0.05 - p<0.01) and cocomitantly lowered Pb and Cd levels in erythrocytes, hair, and urine(p<0.01). Regression analysis showed that only iron intake contributed to significant increases in hemoglobin and serum ferritin. It seems that 25mg of iron supplementation is safe and adequate to improve iron status in school children with suboptimal iron status and it also has the benefit of alleviating Pb and Cd status.

  • Autoimmune hemolytic anemia is a disease characterized with destruction of erythrocytes as a result of antibody produce against patient's own erythrocytes and anemia. Autoimmune hemolytic anemia can be roughly stratified into two groups according to serological features and secondary causes including drugs induced hemolytic anemia. Drugs induced autoimmune hemolytic anemia is very rare in pediatric patients. Even though hematological side effects such as leucopenia, agranulocytosis, eosinophilia, thrombocytopenic purpura and aplastic anemia might occur due to psychotropic drug use; to the best of our knowledge there is no autoimmune hemolytic anemia case due to quetiapine, an atypical antipsychotics, in literature. We hereby describe the first child case of autoimmune hemolytic anemia during quetiapine treatment.We also are pointing out that one should keep in mind serious hematological side effects with atypical antipsychotic drug use with this case report.

  • Hematopoiesis has a pivotal role in the maintenance of body homeostasis. Ironically, several hematological disorder caused by chemicals, drugs, and other environmental factors lead to severe bone marrow failure. Current treatments like stem cell transplantation and immunosuppression remain ineffective to ameliorate this diseases. Therefore, a newtreatment to overcome this entity is necessary, one of them by promoting the usage of medicinal plants. Thus, this study aimed to evaluate the hematopoiesis potency of S. javanica berries and leaves extracts in chloramphenicol (CMP)-induced aplastic anemia mice model. In this present study, several types of blood progenitor cell such as $TER-119^+VLA-4^+$ erythrocytes lineage, $Gr-1^+$ granulocytes, and $B220^+$ B-cell progenitor cells were evaluated by flow cytometry analysis. Accordingly, we revealed that S. javanica berries and leaves extracts significantly promoted $TER-119^+VLA-4^+$ erythrocytes lineage and $Gr-1^+$ granulocytes after exposed by CMP. Thus, these results suggested that S. javanica berries and leaves extracts might have hematopoiesis activity in CMP-induced aplastic anemia mice model.
