On the Antigens of Red Blood Corpuscles
1. Flocculation reactions of anti-erythrocyte sera on emulsions of alcoholic extract of blood are described. 2. The reactions are markedly species-specific. 3. Besides the homologous reactions certain others-"heterogenetic"" ones-have been observed, and in this way the existence of new examples of heterogenetic antibodies has been demonstrated. 4. Group-specific substances can be extracted from...
متن کاملThe Distribution of Sodium, Potassium, Calcium, and Magnesium between the Corpuscles and Serum of Human Blood
A knowledge of the concentration of sodium, potassium, calcium, and magnesium in the blood is necessary in connection with a variety of problems. Methods hitherto used for the quantitative determination of these elements in blood have required large amounts of material even for a single determination and have been, in most cases, difficult to carry out. These facts have tended to discourage suc...
متن کاملThe Factors Concerned in the Appearance of Nucleated Red Blood Corpuscles in the Peripheral Blood
1. Hemorrhage with immediate saline infusion causes the appearance in the peripheral blood of a slightly increased number of normoblasts provided normoblasts are already present in the blood stream. Marrow hyperplasia does not intensify this reaction and the cells found probably do not leave the marrow pulp but are in the blood stream at the time of the experiment. 2. The slight increase in cel...
متن کاملBlood-forming potential of vascular endothelium in the human embryo.
Hematopoietic cells arise first in the third week of human ontogeny inside yolk sac developing blood vessels, then, one week later and independently, from the wall of the embryonic aorta and vitelline artery. To address the suggested derivation of emerging hematopoietic stem cells from the vessel endothelium, endothelial cells have been sorted by flow cytometry from the yolk sac and aorta and c...
متن کاملA Contribution to Our Knowledge of the Action of Saponin on the Blood Corpuscles and Pus Corpuscles
1. The increase of conductivity produced by saponin in formaldehyde-hardened blood is due to an increase in the conductivity of the corpuscles (increased permeability of the corpuscles to ions) and not, mainly at any rate, to the liberation of electrolytes from the corpuscles and a consequent increase in the conductivity of the serum. The increase in the permeability of the corpuscles is probab...
