OBJECTIVES: To ascertain whether some result of hematological examination could be as reference data for health management of welders. METHOD: The authors conducted the hematological examination of 1,018 welders and 531 control workers of a shipbuilding industry in Ulsan using automatic blood analyzer. RESULTS: The WBC count of welders was lower than that of control on controlling the age and the duration of employment, but changes of other blood cells were not observed. CONCLUSION: We could use the results of hematological examination such as WBC counts as an indicator for subtle changes of health status of welders.

The research aimed to establish the maximum time elapsed between collection and analysis of samples. The blood samples were stored at temperature varying from 200C to 280C. Studied on 32 subjects, all samples were marked by the monoclonal antibodies. Each sample had been analyzed 4 times: within 6 hours, 24 hours, 48 hours and 72 hours after drawing. Epi-info 2000 had been used for statistical analysis the results. Results showed that: the maximum elapse of time for the CD4 was 72 hours, for the CD8 was 24 hours and for the lympho and the WBC's as little time as possible, because the results were very different every second time

38 blood samples were divided into 2 groups – normal sample (with 3 groups of cells seen obviously; lymphocyte, mon, gronulocyte on FSC, SSC windows) and abnormal sample group (without these 3 groups of cells).

The initial study of natural protection against HIV-1 infection among exposed uninfected intravenous drug users in Vietnam showed that this people had more immune system with activation than normal people. The peripheral blood monocysts in some people resist disease-induced viruses in vitro by two mechanisms: target cells (T CD4) resist or less sensitivity with HIV-1 virus or inhibit viruses from T CD8 cells

38 Vietnamese adult healthy people studied on peripheral blood and bone marrow material to investigate on hemopoiesis and distribution of blood cells as well as lymphocytic subsets. The results showed that in peripheral blood, the hematologic and lymphocytic count parameters are sames as medical literature. In bone marrow material, nucleated cell count is in strict range with mean value of 54+/- 16G/L. The three common lines of bone marrow are granulocytic, erythrocytic and lymphocytic lines are distributed in distribution of lymphocytic subsets in bone marrow in comparison to peripheral blood. All subsets are more higher than that of peripheral bood about 2.5 to 4 time times with conversely ratio CD4/8.

A total of 47 cord blood collection were analysed for CD 34+ progenitor cells. Results: volume (ml) without anticoagulant 64ml (40-90). Total NC 9.82x108+/- 0.45. Total CD 34+ 1.79x10 +/-1.4. Mean percentage of CD34+: 0.32%+/ 0.24. Given that a transplanted cell dose of 20x106 NC/kg body weight would be sufficient for hematopoiesis, 95% of all stored CB samples would be sufficient for patients up to 10 kg body weight and 36% for patients up to 40 kg body weight.
