Since the crystallizable fragment (Fc) portion of the immunoglobulin G (IgG) molecule is the binding site of Protein A, a radioimmunoassay procedure using 125I-Protein A was developed for identification of the ABO blood groups. The isotope level bound to Group A, B, or AB red cells decreased with the dilution of anti-A or -B, respectively. After sensitization by anti-A plus B in Group O serum, the isotope bindings were observed in Groups A, B, and AB cells, while no significant radioactive count appeared in Group O cells. Furthermore, there was little significant isotope binding in both Group A and B red cells sensitized by the serum from Group A or B blood containing mainly IgM anti-A or -B. A radioimmunoassay using 125I-Protein A is an excellent method for identifying ABO blood groups. 相似文献

Possible use of monoclonal antibodies anti-H in absorption-elution reaction was studied. Blood and secretion stains on gauze were analysed. Practical usefulness of monoclonal antibodies anti-H for investigation of human blood and secretions was stated. Differences in interaction of monoclonal antibodies with traces of different origin were found. 相似文献

Faced with evidence of an appallingly low standard of living which the vast majority of men and women in Nigeria have despite two decades of development and cooperative movements, the Federal and State Governments now attempt to ensure that the real target of development are the human beings who will remain central to all redefinitions and to all revised strategies. This study proposes a theoretical framework for cooperative education and training programmes in the rural areas of Nigeria in order to raise the level of understanding and performance of cooperative members. The approach is primarily an amalgam of the general process model of organization systems and McGrath's problem - based/problem - solving systems. Application of the approach subsequently suggests a method of scientific inquiry which this paper conceives as the Cooperative Education Working Model. To be most effective, Nigerian cooperators must regard cooperative education and training as a vital benefit which their membership provides for them. 相似文献

Trying to optimize the preparation of blood stains, we found methanol fixation not to produce very good results for the determination of ABO blood group antigens. It is advantageous to transfer blood stains before testing to cotton cloth. This transfer is also of practical use if blood stains are to be saved on a smooth surface for lateral determination. We testet on 35 different carrier materials, on which blood stains in casework often were found, whether blood grouping gave better results on either the original material or after transfer. Results are shown on a table. The test revealed, that solubility of the stain in aqua dest is a good sign for a successful transfer. Blood stains on pine-wood soil, soil and loam were not suited for ABO grouping. 相似文献

An extremely rare case of sudden death caused by cardiac rupture due to severe fatty infiltration in the right ventricular myocardium is presented. The patient, a 74-year-old woman, had no history of chest trauma, hypertension, or pulmonary disease. The autopsy showed a small tear in the right ventricle and cardiac tamponade, but no coronary artery lesion. In the right ventricular myocardium, muscle fibers were definitely atrophic or absent, with massive fatty replacement. Fatty infiltration of the myocardium, if severe, can be a cause of serious cardiac dysfunction or, occasionally, sudden death. 相似文献
