Serum protein polymorphisms in the population of south Yemen.

The Gc, Hp, and Tf polymorphisms were studied in the population of South Yemen. The gene frequencies were in agreement with those of other populations in the Middle East. There was an indication of local variations due to ethnic heterogeneity, e.

Transferrin types in different ethnic groups of the USSR and Mongolia.

Transferrin (TF) subtypes were studied in 7 different populations from the Soviet Union (Buryats, Russians, Koreans, Kirghizes and Pamirians) and in 3 different populations from Mongolia. The frequency of the C2 gene varied between 10.4% in Pamirians and 27.

[Distribution of ABO, MN, Rh blood groups and Hp, Tr, Gc and C3 serum factors in the Buryat population].

Polymorphism of blood groups ABO, MN, Rh and serum proteins Hp, Tf, Gc, C3 was studied in Buryat populations of Zabaikalie, Pribaikalie, Olkhon island. No indication of significant heterogeneity was observed. Gene frequencies varied in different systems within the ranges: ABO (p-0.

[Cytogenetic examination of workers engaged in manufacturing of asbestos technical products].

The article contains data on a cytogenetic monitoring of workers engaged in asbestos production, depending on duration of professional service and degrees of dust contamination of the air. The results of the cytogenetic analysis of the peripheral blood lymphocytes in 31 workers revealed the average rate of aberrant cells 1.78% in workers with professional service below 1.

Polymerase chain reaction polymorphisms in HLA-DQ alpha and IL6 from Mongoloid and Caucasoid populations.

Polymerase chain reaction polymorphisms have been used to study European, Chinese, Russian and Buryat populations at the HLA-DQ alpha and IL6 loci. DNA from individuals in these populations was specifically amplified at these loci, and analyzed either with allele-specific oligonucleotides for HLA-DQ alpha or directly on agarose gels for IL6. Allelic frequencies were calculated for each of the loci in each population.
