Background: Normally, gender of human is indentified according to enternal sexual organ. However in several cases the patient\u2019s gender is not able to identify based on enternal sexual organ. In these cases test for gender identification is need. Objectives: Identify relationship between clinical condition of the external sexual organ and sexual chromosome. Subjects and method: 119 patients with diagnosis of \u201cunclear gender identification\ufffd?made by hospitals in Ha noi. Culture of peripheral blood, analyze sexual chromosome, comparing with gender indentification proposed in neonatal period and gender indentified by physical at time of examination. Results: 87/119 cases (73,11%) have male sexual chromosome. According of gender proposed in neonatal period to sexual chromosome are 76,90% for children considered \u201cboy\ufffd?and only 33,33% for \u201cgirl\ufffd? The according percentage is higher at time of examination (mean age is 6,4 years old). There are 4 cases of female phenotype with XY sexual chromosome. Conclusion: In cases with unclear gender identification in neonatal period: 73,11% cases have male sexual chromosome (XY). Apprasal gender at neonatal period is difficulty accurate, especialy for children considered girl (the according rate is only 33,33%). \ufffd?Detect 4 cases of \u201ctesticular femiuization\ufffd?

Background: In Vietnam, there are increase rate of patients with acute leukemia including acute myelogenous leukemia. The clinical, gender, age as well as morphological characteristics of cells have prognostic significance about response to treatment and survival time of patients. Objectives: (1) To describe the distribution of acute myelogenous leukemia types by FAB standard in 'National Institute of Hematology and Blood Transfusion. (2) To describe the clinical characteristics of patients with acute myelogenous leukemia. Subjects and methods: The study included 67 patients diagnosed acute myelogenous leukemia by FAB standard without chemotherapy in 'National Institute of Hematology and Blood Transfusion. Results and conclusions: The median age: 35.55 \xb1 13.46, sex: 53% male, 47% female. Ratio of M0, M1, M2, M3, M4, M5, M6, M7 was 1, 10, 19, 18, 30, 13, 6, 1 %, respectively. 100% of these patients presented with anemia, 57 % with hemorrage, 46 % with fever. Lymphadenopathy was presented in 61 %, hepatomegaly was presented in 27% and spleenomegaly was presented in 9%. 53% of the patients had more bleeding was M3. Lymphadenopathy, hepatospleenomegaly had most frequently seen in the patients of M4 and M5 type. \r\n", u'\r\n', u'

Background: Anti \ufffd?HLA (Human Leukocyte Antigen) antibody is result of immunization in allotransplantation. Organ transplantation is one of the great scientific achievements of the medicine. However, it is difficult to have the perfect harmony of HLA group. Inevitable consequence is the graft will be eliminated by the immune process. In Vietnam, organ transplantation was a relatively new specialty and there was not much research on evaluation immune process after transplantation. Objectives: To determine the rate of present of anti \ufffd?HLA antibody on transplant patients, and the role of post \ufffd?transplant anti \ufffd?HLA antibodies on long \ufffd?term graft function. Subjects and method: ELISA technique was used to analysis 31 blood samples of 31 patients who were transplanted organs at 103 military hospital and Cho Ray hospital from May 2000 to July 2007. This was a retrospective and described cross-sectional study on theclinical records. Results:The rate of anti \ufffd?HLA antibodies was 35.5%. The present of anti \ufffd?HLA antibodies of transplant patients had negative impact on graft function. Conclusion: The detection of anti \ufffd?HLA antibodies by ELISA in the post transplant period may be a high confident and sensitive technique for follows up graft function.

Background: The reduction of erythrocytes from cord blood is very need for long - term storage of C034 cells for transplantation. Reduced erythrocyte will reduces preservative blood volume, preservatives and freely HST when defrosting, so stem cells are better protected. Objectives: To study selection of the best centrifugal procedure to reduce maximal erythrocytes and lose minimal C034 cells from cord blood. Subjects and methods: 20 blood samples selected from 60 cord blood units was used for this study. The study was carried out through two steps. In the first step, the centrifugal speed was fixed and the centrifugal time was changed.In the second step, the centrifugal time was fixed, the centrifugal speed was changed. From collected results the best appropriate procedure to reduce erythrocytes from cord blood have been selected. Results: The procedure of gradient centrifuge with speed of 500g in 6 minutes isolated> 50% of erythrocytes, kept > 84% of CD34 cells and then centrifuge of 1000 g in 10 minutes reduced about 40% of volume of nuclear cell - suspension. Conclusion: The procedure can use for preparation of stem cell suspension from cord blood to storage in nitrogen liquid. \r\n', u'\r\n', u'

Background: Detection of BCR/ABL fusion gene has important significance in diagnosing and monitoring response to therapy in chronic myeloid leukemia. Objective: Application of FISH (Fluorescence In Situ Hybrydization) technique for detection of abl/bcr fusion gene in chronic myelogenous leukemia. Subjects and methods: The study included 10 patients of chronic myelogenous leukemia diagnosed by methods of morphology and cell chemistry. Peripheral blood and bone marrow samples of them were analyzed Philadelphia (Ph1) chromosome by cytogenetic technique. Among them, 5 patients were tested by FISH technique on the slide of interphase and remainders were tested by FISH technique on the slide of metaphase cell. Results: Results of analyzing chromosome of 10 patients showed that 8 patients had Ph1 chromosome. 2 patients without Ph1 chromosome were patients who had not high of leukocyte count: 28x109leukocyte/l and 36x109leukocyte/l, respectively. In the FISH on the slide of interphase, all 5 patients had Ph1 chromosome and abl/bcr fusion gene. In the FISH on the slide of metaphase cell, 3 patients had Ph1 chromosome and abl/bcr fusion gene. Conclusion: FISH technique has been applied successfully to detect ABL/BCR gene in patients with chronic myelogenous leukemia.\r\n', u'\r\n', u'
