RESUMEN
The phenotype and gene frequencies of HLA class I were studied in the Northeastern Thai population. Blood samples were collected from 100 unrelated healthy Northeastern Thais. HLA-A and B antigens were typed by using the standard microlymphocytotoxicity test. Twelve HLA-A and twenty-five HLA-B antigens were found in this population. HLA-A2, A24, A11 and the HLA-B46, B15, B22 antigens are commonly found in this group. Linkage disequilibrium analysis indicated the existence of fifteen haplotypes. The HLA-A2, B46 haplotype was the most common. These results will be useful for further studies in anthropology, organ transplantation and MHC associated disease in Northeastern Thais.

The anti-HTLV-I prevalence was studied by particle agglutination technique (PA) in 2,609 samples including: 403 antenatal care women from Srinagarind Hospital, Faculty of Medicine, 342 high-risk sexually transmitted disease blood donors and 1,864 randomly selected blood donors from the Blood Transfusion Centre, Faculty of Medicine, Khon Kaen University. All of the 2,609 samples gave negative anti-HTLV-I. The result revealed that HTLV-I infection is not common in northeast-Thailand. However, as the sample size from this study may be too small, further study should be carried out.
