Sera of patients with infectious mononucleosis contain heterophile anti-Paul- Bunnell (PB) antibodies to erythrocytes of numerous mammalian species. Evidence is presented that the corresponding antigen of bovine erythrocytes is not, as previously described, a single molecule, but a series of glycoproteins with glycans terminated with N-glycolylneuraminic(More)
Leukemic leukocytes from 12 patients with acute myelogenous leukemia (AML) and two patients with chronic myelogenous leukemia (CML) were isolated by centrifugations in Percoll gradients, and examined for total carbohydrates. In leukemic leukocytes from 10 of these patients ceramide-bound carbohydrates were also determined. Protein-bound carbohydrates were(More)
Congenital dyserythropoietic anaemia type II (CDA II) is well known for glycosylation abnormalities affecting erythrocyte membrane glycoconjugates that encompass hypoglycosylation of band 3 glycoprotein and accumulation of glycosphingolipids: lactotriaosylceramides, neolactotriaosylceramide and polyglycosylceramides. These abnormalities were not observed in(More)
UNLABELLED THE AIM of the study is a genetic analysis of hereditary chronic nonspherocytic anaemia in a case, caused by mutation in the glucose-6-phosphate dehydrogenase gene. MATERIALS AND METHODS The activity of G6PD enzyme was established. PCR method and DNA sequencing were implemented for molecular studies. Bioinformatic methods were used to check the(More)
The kinetics of interferon production, induced by poly I:C in the presence of DEAE dextran, was studied in Lpa cells. Optimal interferon production was obtained at concentration of 10 micrograms/ml poly I:C and 200 micrograms/ml DEAE dextran. Transfer RNA applied to Lpa cells during induction and synthesis of interferon resulted in continuous production of(More)
UNLABELLED A patient of 31 years of age with an atypical overhydrated hereditary stomatocytosis is described. The diagnosis was established on the basis of a markedly increased red cell volume with low MCHC, high osmotic fragility of red cells, but increased binding of eosin-5-maleimide (EMA) to red cells, presence of stomatospherocytes and large(More)
