1. The defects produced on the membrane of the human red blood cell by the action of complement and antibody have been studied by the use of the electron microscope. These are round to slightly ovoid holes and are surrounded by an irregular ring, about 20 A thick. The mean diameter of the holes is about 103 A if human complement is used (regardless of the antibody used for sensitization) and ab...
The red cells of patients with hereditary erythroblastic multinuclearity with a positive acidified serum test (HEMPAS), a form of congenital dyserythropoietic anemia, and the cells of patients with paroxysmal nocturnal hemoglobinuria (PNH) are lysed more readily than normal cells by certain antibodies, notably cold agglutinins (anti-I) and complement. With some but not other examples of anti-I,...

Published by Elsevier B With about 3–5 million severe cases and 250.000–500.000 deaths yearly, seasonal influenza infections form a constant and serious threat to the human population (Influenza (Seasonal) Fact sheet, n.d.). In addition, new influenza virus strains, often originating in birds or pigs, may cross the sp...
2-Aminoethylisothiouronium bromide (AET) increases the sensitivity of blood cells to complement-mediated immune lysis. We compared the sensitivities of untreated or AET-treated platelets to immune lysis induced by different types of platelet antibody in the 51Cr platelet lysis test. AET platelets were 8-16 times more sensitive to autoantibody and alloantibody, but 8-16 times less sensitive to d...
BACKGROUND/AIMS Patients who undergo repeat kidney transplantations (KTs) are considered at high risk for experiencing immunologic and non-immunologic complications. In this study, we investigated the clinical outcomes, including medical and surgical complications, of patients who underwent a third KT at our center. METHODS Between March 1969 and December 2012, a total of 2,110 KTs were perfo...
