Further Studies with Toxic Serum Extracts of Hemolytic Streptococci
1. The same Streptococcus hemolyticus organisms may be subjected to extraction six times in 2 days with untreated inactivated serum with no loss in potency of the later extracts when the organisms are kept frozen solid during the night between the extractions. 2. The serum extract toxins of hemolytic streptococci can be preserved without deterioration for at least 6 months if kept frozen solid....
متن کاملSerum lipoperoxidation products in an infant with hemolytic-uremic syndrome.
We detected increased concentrations of lipoperoxidation products, as malondialdehyde, in the serum of an infant with classic hemolytic-uremic syndrome. The concentrations declined when peritoneal dialysis was initiated and eventually returned to normal after clinical recovery. Our observation adds to the existing body of evidence that links the pathogenesis of hemolytic-uremic syndrome to pero...
متن کاملQuantitative Immunology of Immune Hemolytic Anemia
INTRODUCTION The commonest form of autoimmune hemolytic anemia is characterized by the presence of antibody of the IgG immunoglobulin class on the red cell (1). These antibodies characteristically react with red cell antigens at body temperature, and they fix complement relatively inefficiently since two antibody molecules in juxtaposition are required to initiate a complement sequence (2). The...
متن کاملQuantitative serum immunoglobulin tests.
What is the test? Immunoglobulins are protein molecules. They contain antibody activity and are produced by the terminal cells of B-cell differentiation known as 'plasma cells'. There are five classes of immunoglobulin (Ig): IgG, IgM, IgA, IgD and IgE. In normal serum, about 80% is IgG, 15% is IgA, 5% is IgM, 0.2% is IgD and a trace is IgE. Quantitative serum immunoglobulin tests are used to de...
متن کاملSerum Factors of Acquired Hemolytic Anemia in Leukemia and Lymphoma.
The purpose of this study was to determine whether the abnormal serum factors of acquired hemolytic anemia in patients with leukemia and lymphoma could be characterized as antibody by the immune adherence technique. The pathogenesis of this disorder has not been completely explained and it was felt that the study of specific immunologic reactions might help to determine whether these serum fact...
