NTIGENIC DIFFERENCES among human leukocytes are well established,14 and it is known that patients can be immunized against donor leukocytes with the development of agglutinating antibodies.5 Antibodies against leukocytes have been found in patients subjected to repeated blood transfusions, and the incidence of such immunization appears to be proportional to the number of transfusions given.6’7 ...

A comparative study of serum biochemical and hematological parameters from Andinoacara rivulatus Ichthyoelephas humeralis in Los Ríos Province, Ecuador, was carried out. Two the native species that are most commercialized Quevedo, Mocache Fumisa, were identified; 60 specimens captured each area (180 total). factorial design (3×2) used: three habitat zones (Fumisa, Mocache) two (A. I. humeralis)...

A microassay for assessing two functions of polymorphonuclear leukocytes in the presence or absence of complement is presented. Requiring only minute amounts of blood (0.1 ml) and a minimum of laboratory equipment (microscope, incubator, and centrifuge), it allows the quantitation of phagocytosis and intracellular killing of microorganisms by leukocytes. To demonstrate the value of this assay, ...
