  • Fifty four strains of pathogenic vibrios were isolated from the Gwangan Beach from May to October, 2002. The isolated vibrios were composed of 7 different species: Vibrio parahaemolyticus, V. cholerae non-O1, V. alginolyticus, V. vulnificus, V. hollisae, V. fluvialis, ane V. mimicus. In the detection rate, V. parahaemolyticus was most predominant as $46\%$(25/54). From the isolated strains, only 25 strains have hemolytic activity or 25 strains only proteolytic activity on agar plates. Eleven strains showed both hemolytic and proteolytic activity. No strains showed urease activity. All strains of V parahaemolyticus did not show hemolytic activity, while V. cholerae non-O1 strains showed $\beta$ hemolytic activity. Kanagawa phenomena of pathogenic vibrios did not accord with hemolytic activity of the culture supernatant at the late log phase. Some strains showed high hemolytic activity despite having proteolytic activity, but some weak hemolytic activities despite having no proteolytic activity.

  • 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.

  • Hemolytic reaction of normal fresh chicken serum on sheep erythrocytes was studied and the following experimental results were obtained and summarized. 1. Chicken sera, 258 (78%) out of 344 samples showed hemolytic activity on sheep erythrocytes. 2. Distribution of a different hemolytic titer of chicken sera was not dependent to sex and age difference of test chicken. 3. Hemolytic activity of serum component obtained from normal fresh chicken was heat inactivated at $56^{\circ}C$. 30 minutes heating. 4. The most enhanced hemolytic activity of chicken serum on sheep erythrocytes was observed at the incubation temperature of $46^{\circ}C$. 5. The most effective pH for the hemolytic reaction of chicken serum on sheep erythrocytes was observed at 7.0, and pH 6.0 or 8.5 resulted less or no hemolysis. 6. Hemolytic reaction of chicken serum and sheep erythrocytes required Mg⧻ and Ca⧻ ions as, co-factor, and the former was required more compared to the latter. 7. Hemolytic activity of chicken serum was observed in ChC 2, 4 fraction but not in ChC 1, 3, ChC 3, 4, ChC 1, 2, 4 and ChC 1, 2, 3 fractions. 8. In electron micrography, morphological changes of sheep erythrocyte membrane by normal chicken serum was similar to that of immune hemolysis: that was, the hemolytic hole was circular and it was surrounded with a white ring. 9. Electron micrography of morphological changes on sheep erythrocyte membrane indicated that the size of hemolytic hole and white ring were functional to the chicken serum concentration used and reaction time.

  • Liposomal restructuring induced by hemolytic Listeria monocytogenes was investigated by using flow cytometry. When added to calcein-entrapped liposomes, hemolytic, but not non-hemolytic, Listeria monocytogenes were able to induce reformation of vesicles. Such restructuring of liposomes was easily monitored by flow cytometry. Electron microscopy also indicated major changes in the challenged liposomal structures. The preliminary results described may offer a simple and fast method for monitoring liposomal restructuring and for differentiating between hemolytic and non-hemolytic bacteria.

  • Hemolytic uremic syndrome is a clinical syndrome with various etiology and pathogenesis. And pneumococcal neuraminidase has been known to play a pathogenetic role in some cases with this syndrome. We experienced two children with hemolytic uremic syndrome complicated by pneumococcal infection. One was 21-month-old girl with pneumococcal pneumonia, and the other was 7-month-old girl with pneumococcal meningitis and sepsis. Both of them showed typical clinical manifestations of hemolytic uremic syndrome with prolonged anuria during the course of pneumococcal infection. The renal functions of both cases did not recovered after resolution of acute hemolytic episode and chronic renal failure developed.

  • Hemolytic anemia and thrombocytopenia are rare clinical manifestations of acute glomerulonephritis. Initially, in all such cases, a diagnosis of hemolytic uremic syndrome, thrombotic thrombocytopenic purpura, systemic lupus erythematosus, and amyloidosis should be ruled out. The presence of hemolytic anemia and thrombocytopenia is rare, but possible, in a case of acute poststreptococcal glomerulonephritis, and may result in delayed diagnosis or misdiagnosis. Correct and timely diagnosis would ensure adequate treatment in such patients. We report of a 22-month-old boy with acute glomerulonephritis coexistent with hemolytic anemia and idiopathic thrombocytopenia.

  • Bacillus subtilis ATCC 6633 was grown in BHIB medium supplemented with $Mn^{2+}$ for 96 h at $37^{\circ}C$ in a shaker incubator. After removing the microbial biomass, a lipopeptide biosurfactant was extracted from the supernatant. Its structure was established by chemical and spectroscopy methods. The structure was confirmed by physical properties, such as Hydrophile-Lipophile Balance (HLB), surface activity and erythrocyte hemolytic capacity. The critical micelle concentration (cmc) and erythrocyte hemolytic capacity of the biosurfactant were compared to those of surfactants such as SDS, BC (benzalkonium chloride), TTAB (tetradecyltrimethylammonium bromide) and HTAB (hexadecyltrimethylammonium bromide). The maximum hemolytic effect for all surfactants mentioned was observed at concentrations above cmc. The maximum hemolytic effect of synthetic surfactants was more than that of the biosurfactant produced by B. subtilis ATCC 6633. Therefore, biosurfactant would be considered a suitable surface-active agent due to low toxicity to the membrane.

  • To investigate the hemolytic toxicities of the Korean basidiomycetes, the cold-water extracts of 22 wild mushrooms were tested for their hemolytic activities on the erythrocytes of a mouse and a rat. As a result, three species including Collybia confluence, Laccaria vinaceoavellanea and Lenzites betulina showed strong hemolytic activities. Of these, L. vinaceoavellanea retained more than 80% of its hemolytic activity even after it was boiled for 30 minutes, while the other two were inactivited in five minutes.

  • Cholelithiasis is rarely recognized in children, especially in infants. Hemolytic disorders, long-term total parenteral nutrition (TPN), congenital anomalies of the biliary tree leading to stasis of bile flow, congenital IgA-deficiency, furosemide treatment, and prolonged fasting have been reported as predisposing factors for cholelithiasis in childhood. Hemolytic disease of the newborn due to anti-E has rarely been reported as a risk factor for cholelithiasis. We report a case of gallbladder stones in a neonate associated with anti-E antibody hemolytic disease.

  • Atypical hemolytic uremic syndrome associated with neuraminidase-producing Streptococcus pneumoniae usually associated with invasive infection such as fulminant pneumonia, sepsis, and meningitis and may occur earlier in lift and has a higher mortality rate than typical hemolytic uremic syndrome. We have experienced a 22-month-old female patient with hemolytic uremic syndrome associated with S. pneumoniae pneumonia and empyema. The patient was treated with ceftriaxone and washed red blood cell transfusion. As the disese course could be aggravated by the use of blood products containing anti-Tomsen-Friedenreich antigen, early recognition and sensible use of blood products such as washed RBC might lead to the improved outcome.
