Clinically, the Rh blood group system is important since Rh antibodies are readily induced by transfusion or pregnancy in individuals negative for the antigert and may cause hemolytic reactions or hemolytic disease of the newborn. Since the D antigert is strongly immunogenic, donors and patients are routinely typed for D status and patients are generally given D compatible blood. But under several circumstances such as spontaneous agglutination of red blood cells coated with immunoglobulin, antisera with additives may cause false positive results in test using high-protein reagents. And facton in the patient' s own serum may also affect the test, since unwashed red blood cells suspended in their own serum or plasma are frequently tested. Therefore, manufacturers and American Association of Blood Banks(AABB) recommend that the Rh(D) control test with Rh(D) control reagent which contains the same additive present in high-protein anti-D except for the anti-D. This study was undertaken to evaluate the usefss of the Rh(D) control test in Korea where Rh(D) negative population is small. Red blood cells from 1115 in-patients and 468 out-patients at Korea University Medical Center were employed in Rh(D) typing and Rh(D) control test in parellel. 1580 cases are Rh(D) positive and 3 cases were Rh(D) negative. No agglutination was observed with Rh(D) control test. Though AABB and manufacturers recommended that the Rh(D) control test should be done in parellel with Rh(D) typing test, the authers concluded that there were no need to run the Rh(D) control test in Korea.

Human lymphoblastoid B-cell lines immortalized by Epstein-Barr virus (EBV) were established from peripheral blood of patients with acute myeloblastic and chronic lymphocytic leukemia and chronic fatigue syndrome. The sera of patients with acute myeloblastic and chronic lymphocytic leukemia did not show antibodies to Epstein-Barr viral capsid antigen (VCA), but serum of a patient with chronic fatigue syndrome disclosed antibodies to VCA (IgG, IgM), and EBNA was demonstrated in peripheral blood mononuclear cells by polymerase chain reaction. The established cell lines were mature B-cell phenotypes with polyclonal proliferation in early passage and no evidence for commitment to other lineages. The immortalized cells by EBV were designated as CSUP-1 and CSUP-2 (from acute myeloblastic leukemia, FAB classification M2 and M1), CSUP-3 (from chronic lymphocytic leukemia) and CSUP-4 (from a patient with chronic fatigue syndrome). The CSUP-1, 2, 3, and 4 grew in suspension forming clumps with a doubling time of 38 to 49 hours. Colony formation was not recognized in plate. By light and electron microscopic examination, the immortalized cells showed features of lymphoblastoid to plasmacytoid lymphocytes, and multinucleated giant cells. The lymphoblastoid cells showed scanty cytoplasm with poorly developed organelles. Immunophenotypic analyses of CUSP-1, 2, 3, and 4 with monoclonal antibodies by flow cytometry showed B-cell phenotype with polyclonal proliferation in early passage. Epstein-Barr virus nuclear antigen was confirmed in the extracted DNAs from immortalized cells by polymerase chain reaction. DNA analysis showed a normodiploid stemline with a DNA index of 1.12. The established cells were strongly reactive for CD10, CD30 (Ki-1) in early passage, and bcl-2 and c-myc onco-protein in early and late passage. Karyotypic analysis of CSUP-1, 2, 3 and 4 showed 46, XY or 46, XX. No tumorigenesis in heterotransplanted SCID mouse was recognized. This immortalized cells by EBV should be a valuable cell lines to study the pathogenesis of EBV-related malignant lymphoma.
