  • Schwann cells and neuron cells from dorsal root ganglion (DRG) in embryos of rat were cultured in vitro respectively. The purified neronal cells added with anti-mitotic agents and purified Schwann cells were cocultured and then accomplished myelination processing. Infection of Semliki forest virus into this myelinated co-culture system was performed and then accomplished demyelination. We identified myelination and demyelination processing using antibody of neuropeptide Y meaning presence of myelinated neuron.

  • $M_4$-LDH isozyme was partially purified from the skeletal muscle of Agkistrodon blomhoffii brevicaudus. The protein was injected into rabbits and the resulting antiserum was tested for reactivity with crude preparations of LDH isozymes of fifteen vertebrate species. Antisera against $M_4$-LDH isozyme of A. blomhoffii brevicaudus reacted very strongly with the LDH isozymes, except the $H_4$-LDH isozyme, of A. saxatilis and A. caliginosus but weakly with those of Rhabdophis tigrinus at fixed conditions. A. caliginosus showed a difference in the immunodiffusion test and was considered to be a species less related to others of genus Agkisrodon. The suggestion that the H and M lactate dehydrogenase subunits are immunclogically distinct has been reaffirmed in the present study.

  • The vaccine is biological pretreatment that improves immunity to a particular disease. We can get immunity from producing antibody with injection antigen which has ability to defense against the disease. The ELISA is the most widely used method to measure antibody titer. We have developed and performed validation of ELISA according to the guideline of KFDA and ICH. In this paper, we have verified ELISA method is an excellent method to measure the titer of anti-PA antibody. We have constructed recombinant protective antigen among anthrax toxins and used as antigen of ELISA. In this validation, we have evaluated precision (repeatability, interlaboratory precision), specificity, linearity(range) and LOD, which are validation articles suggested by guideline. Inter-person precision was replaced with inter-laboratory precision. From the results, we have confirmed high precision in all experiments with CV under 20%.

  • Systemic lupus erythematosus (SLE) is a chronic autoimmune disease that may affect many organ systems including the nervous system. The immune response in patients with SLE can cause inflammation and other damage that can cause significant injury to the arteries and tissues. A 48-year-old woman was admitted to the hospital because of transient monocular blindness. Magnetic resonance imaging and conventional angiography showed severe stenosis of the distal intracranial internal carotid artery. The patient was diagnosed as having SLE but the antiphospholipid antibodies were negative. Amaurosis fugax has not been previously reported as an initial manifestation of SLE in Korea. We report a patient with a retinal transient ischemic attack as the first manifestation of SLE.

  • Objectives: This study was performed to analyze randomized controlled trial, which studied the effect of herbal medicine treatment on Antiphospholipid antibody positive recurrent abortion. Methods: We searched for randomized controlled trial of last 20 years based on Antiphospholipid antibody positive recurrent abortion and herbal medicine. The paper search was conducted through 7 online databases on July 16, 2022. Results: 9 studies were selected after selection and exclusion criteria. 5 studies compared combined treatment of herbal and western medicine, with western medicine alone. 4 studies compared herbal medicine alone with western medicine. Comparing with control group, the treatment group showed much improvement on conversion rate of anti-phospholipid antibodies, serum hCG and progesterone levels, pregnancy duration or fertility rates, and various symptoms. Conclusions: In this study, we found out benefit of herbal medicine with Antiphospholipid antibody positive recurrent abortion. For reliable evidence, further research is needed to establish safety of herbal medicines, standardize symptom criteria and specify the treatment course.

  • Several studies have reported a possible link between anti-aquaporin-4 antibody and vitamin B12 deficiency in neuromyelitis optica spectrum disorder (NMOSD). Bilaterally symmetric hyperintense signals on magnetic resonance imaging (MRI) of the posterior columns, called the inverted V sign, are a characteristic feature of subacute combined degeneration associated with vitamin B12 deficiency. We report a patient with anti-aquaporin-4 antibody-positive NMOSD and an inverted V sign on MRI of the spinal cord and address the association between anti-aquaporin-4 antibody and functional vitamin B12 deficiency.

  • Purpose : Four kinds of Haemophilus influenzae type b protein conjugate vaccines, PRPD, PRP-T, PRP-OMP and PRP-CRM197, have been developed, and PRP-T vaccines are currently produced by two manufacturer, $ActHib^{(R)}$ by Aventis and $Hiberix^{TM}$ by GlaxoSmith-Kline Biologicals. The purpose of this study is to evaluate the immunogenicity and safety of $Hiberix^{TM}$ in Korean infants. Methods : Seventy-three healthy infants(43 male infants) were recruited for this study after parental informed consent was obtained. Each infant was vaccinated at 2, 4 and 6 months of age with the study vaccine. At each visit, infants were also immunized with DTaP, trivalent oral polio vaccine and hepatitis B vaccine when indicated. The serum anti-PRP antibody was measured at prevaccination, 2 month later after the 2nd dose, and 1 month later after the 3rd dose by the ELISA method. The local and systemic adverse reactions of vaccination were monitored for 3 consecutive days after each immunization. Immunogenicity of vaccine was evaluated in infants who received all the scheduled immunization and the adverse reactions were evaluated for infants who received at least one dose of the study vaccine. Results : Among seventy three infants, enrolled in this study; sixty three(37 male infants) completed all the scheduled immunizations. The geometric mean titer(GMT) of anti-PRP antibodies at prevaccination was 0.17 ${\mu}g/mL$(95% confidence interval[CI]; 0.13~0.22). The GMT of anti-PRP antibodies increased to 4.14 ${\mu}g/mL$(95% CI; 2.65~6.48) at 2 month later after the 2nd dose of PRP-T and 14.65 ${\mu}g/mL$(95% CI; 10.83~19.81) at 1 month later after the 3rd dose. Anti-PRP antibody ${\geq}0.15$ ${\mu}g/mL$, was observed in 98.4%(95% CI; 91.8~100) after 2 doses and 100%(95% CI; 100~100) after 3 doses. Anti-PRP antibody ${\geq}1.0$ ${\mu}g/mL$, was obtained in 77.8%(95% CI; 67.5~88.0) after 2 doses, and 98.4%(95% CI; 95.3~100) after 3 doses. Most of the adverse reaction after vaccination were mild. Irritability, the most common systemic reaction, was observed in 45.5%, followed by drowsiness(30.5%), poor feeding(26.7%) and fever(5.6%). Among the local reactions tenderness was observed in 7.9%, redness(${\geq}5$ mm) in 2.8% and swelling(${\geq}5$ mm) in 1.8%. Conclusion : The PRP-T vaccine used in this study was highly immunogenic and safe in Korean young infants. The finding that high GMT and high frequency of infants with a protective titer achieved after 2 doses is consistent with the previous studies which were done with a PRP-T vaccine of other manufacturer. This study suggests that the immunization schedule of PRP-T vaccine for Korean infants may need re-evaluation.

  • This study was undertaken to identify the distribution of T and B lymphocytes in bovine peripheral blood and various lymphoid tissues by the method of ABPC using RABTS, $BLT_1$ and $_6E_{12}$ as primary antibodies. RABTS, $BLT_1$ and $_6E_{12}$ positive cells in PB-MNCs were 70.9${\pm}5.5%$, $59.0{\pm}8.7%$ and $23.0{\pm}8.7%$, respectively. $BLT_1$ and $_6E_{12}$ positive cells in nylon wool nonadherent cells of PB-MNCs were $91.6{\pm}1.0%$ and $9.6{\pm}0.8%$, respectively. In the lymphoid tissues such as inguinal lymph node, mesenteric lymph node, spleen and thymus, positive cells of RABTS were $76.3{\pm}3.4%$, $74.2{\pm}8.2%$, $73.6{\pm}5.5%$ and $95.6{\pm}2.8%$, those of $BLT_1$ were $56.4{\pm}6.2%$, $55.6{\pm}7.7%$, $48.6{\pm}5.1%$ and $23.0{\pm}4.8%$ and those of $_6E_{12}$ were $45.3{\pm}7.4%$, $42.3{\pm}5.8%$, $48.5{\pm}6.2%$ and $5.6{\pm}2.1%$, in order. These results are indicating that nylon wool column method is effective for separation of bovine ocytes.

  • This study was carried out in order to identify the biochemical and serological characteristics of Edwardsiella tarda isolated from cultured flounder, Paralichthys olivaceus in the east and south coast of Korea. During the year of 1990 and 1991, the number of isolated E. tarda were 131 strains. To identify the biochemical characteristics of them kinds of tests were conducted. The results represented that all the strains had the same biochemical characteristics, and their biochemical characteristics were no differences among strains. A serological analysis was carried out based on agglutination test with antiserum belonging to E. tarda serotype a (E-22), b (SU-138), c (SU-100) classfied in japan. The selected 10 isolates showed agglutinin titer of 5120-2560, 40-80 and below 40 against E. tarda serotype a, b and c, respectively. Sodium dodecyl sulfate polyacrylamide gel electrophoresis(SDS-PAGE) profiles of cell proteins of selected 10 isolates were showed no differences in kinds and volumes of proteins among strains.
