Abstract Chronic congenital aregenerative anemia describes a "pure red-cell" anemia in which the failure of hematopoiesis is restricted entirely to the erythrocytes without simultaneous impairment of leukocyte or platelet production. The separation of this entity from the category of the increasing number of cases designated as hypoplastic anemia will facilitate a more direct examination of the factors involved in its pathogenesis. In the case described in this paper illustrating this condition, the onset of the anemia dated to the newborn period with the clinical and hematologic features of a mild type of erythroblastosis fetalis. The mother’s blood group was O, Rh positive and that of the infant and father A, Rh positive. The anti-A serum titer in the mother reached a maximum of 1:128,000. The infant was shown to be a non-secretor. The patient, now 17 months of age, requires repeated transfusions to maintain normal blood levels. The bone marrow reveals a persistent depression of erythropoiesis but the platelet and granulocyte levels are entirely unaffected. It is postulated that prolonged depression in red blood cell production may result from an antibody directed solely against the red cells in fetal life or from the early neonatal period. This concept finds substantiation in other cases of erythroblastosis in which temporary failure of erythropoiesis as confirmed by bone marrow studies is reflected in a state of protracted anemia.

Human blood groups (ABO) are known to be determined by the terminal glycosyl residues attached to common carbohydrate chains of the red cell surface. N-acetylgalactosaminyltransferase (A-enzyme) in blood group A persons and galactosyltransferase (B-enzyme) in blood group B persons are responsible for producing A and B substances on the red cell surface, with both enzymes absent in blood group O persons. The plasma transferase (A - and B-) activity was assayed after the complete replacement of the bone marrow of patients with acute leukemia or aplastic anemia by transplantation bone marrow from donors with ABO blood group differing from the recipient. The patient's blood type completely changed from the recipient's type to the donor's type. However, the A- and B-enzyme activities of the patients changed only slightly after bone marrow transplantation. The results indicate that most of the A- and B-enzymes in the circulatory plasma is not derived from the bone marrow, lymphoid, or macrophage tissue. Other tissues must be the primary source of the enzymes in plasma.

Abstract The D antigen content of nucleated red cell precursors in human bone marrow was estimated using autoradiography and 125I-anti-D. D antigen first appeared in the pronormoblast, and the quantity of antigen progressively increased during red cell maturation. Maximal anti-D binding occurred on mature red blood cells. Pronormoblasts, basophilic normoblasts, polychromatophilic normoblasts, and orthochromatic normoblasts, respectively, had approximately 1/4, 1/2, 2/3, and 3/4 the quantity of antigen found on mature red cells. None of the other cell types were found in bone marrow labeled with anti-D.

SummaryPatients with coronary artery disease who undergo FDG PET for therapy monitoring after intracoronary progenitor cell infusion (PCT) show an increased bone marrow up-take in some cases. Aim of the study was to evaluate the systemic bone marrow glucose metabolism in this patient group after PCT. Patients, methods: FDG bone marrow uptake (BMU), measured as standardized uptake value (SUVmax) in the thoracic spine, was retrospectively evaluated in 23 control patients who did not receive PCT and in 75 patients who received PCT 3 ± 2.2 days before PET scanning. Five out of them were pretreated with granulocyte colony-stimulating factor (G-CSF) 5 days prior to PCT and 10 ± 1.2 days before PET scanning. In 39 patients who received only PCT without G-CSF and underwent PET therapy monitoring 4 months later, baseline and follow up bone marrow uptake were measured. Leucocytes, C-reactive protein (CRP) levels and the influence of nicotine consumption were compared with the BMU. Results: In patients (n = 70) who received PCT without G-CSF, BMU median (1.3) was slightly, but significantly higher than in the controls (1.0) (p = 0.02) regardless nicotine consumption. BMU did not change significantly 4 months later (1.2) (p = 0.41, n.s.). After G-CSF pretreatment, patients showed a significantly higher bone marrow uptake (3.7) compared to patients only treated with PCT (1.3) (p = 0.023). Leucocyte blood levels were significantly higher in patients with a BMU ≥ 2.5 compared to patients with a bone marrow SUVmax < 2.5 (p <0.001). CRP values did not correlate with the BMU (rho -0.02, p = 0.38). Conclusion: Monitoring PCT patients, a slightly increased FDG BMU may be observed which remains unchanged for several months. Unspecific bone marrow reactions after PCT may be associated with increased leucocyte blood levels and play a role in the changed systemic glucose BMU.

Abstract Serial determinations of red cell volumes were made with an electronic sizing device in 30 patients with hepatic cirrhosis. Variations in red cell volumes were correlated with other hematologic and clinical findings. The results of these studies suggest that volume macrocytosis in patients with alcoholic cirrhosis is either due to megaloblastosis of the bone marrow or to an accelerated influx of young red cells into the peripheral blood.

Blood Grouping

Karyotyping and blood grouping methods were used to identify sheep twin chimaeras. Evidence that an exchange of blood cell precursors (the origin of chimaerism) had taken place in utero was obtained by examining lymphocytes in culture and finding the chromosomes of both sexes in one individual, or by finding admixture of red cell antigens, haemoglobin or ‘X ’ protein. Where chimaerism of sex chromosomes was found the pairs had identical red cell types, but two separate populations of red cells were not always identifiable. The four females in the pairs studied were freemartins. No correlation was found between the relative proportions of the two red cell populations and those of the two white cell populations. In one pair of chimaeric ewes, breeding tests showed that the major red cell populations in each case were the true genetic type. In the freemartins no correlation was found between the degree of masculinity and the numbers of male lymphocytes. A possible correlation of masculinity with red cell proportions is discussed.
