Variation was more marked in the Bangkok population. In the rural area, with an exclusively northeastern Thai population the Pi-alleles M, S and Z were detected. A1PI serum concentrations measured by electroimmunoassay were slightly higher in Thai than the values reported from European countries; children with Pi M from rural areas had slightly higher A1PI serum concentrations than Pi M children from Bangkok. © 1980 Springer-Verlag.Mahidol UniversityBiochemistry, Genetics and Molecular BiologyMedicineArticleSCOPUS10.1007/BF00279061
