[Possibility of the development of non-transfusion hemosiderosis in beta-thalassemia, caused by association with HLA-linked hemochromatosis]. / Vozmozhnost' netransfuzionnogo gemosideroza pri beta-thalassemii, obuslovlennogo assotsiatsiei s gemokhromatozom, stseplennym s HLA.

The data of HLA-haplotyping were used as an allele marker controlling hereditary hemochromatosis in 23 patients with beta-thalassemia. The results obtained have permitted a conclusion that hemosiderosis in patients with beta-thalassemia may be caused by association of beta-thalassemia gene with hereditary hemochromatosis. Early diagnosis of hyperferremia is of great prognostic importance as the adequate treatment timely conducted can prevent the development of irreversible changes in the patients.

[Immunologic typing of splenic lymphocytes from human fetuses--donors of pancreatic islet cell cultures]. / Immunologicheskoe tipirovanie limfotsitov selezenki vnutriutrobnykh plodov cheloveka--donorov kul'tur ostrovkovykh kletok

To determine the HLA-phenotype of a potential donor of pancreatic islet cells, use was made of lymphocytes from 18-25-week-old human fetuses. The HLA-phenotype was clearly established in 39 out of 52 cases. In 13 cases, the authors failed to reveal histocompatibility antigens because of low viability of lymphocytes. The relationship was ascertained between the detectability of HLA-antigens in fetal donors and cytophysiological characteristics of islet cell cultures prepared from the pancreas.
