The influence of serum natibodies and thermolabile serum factors on the intracellular killing of Staphylococcus aureus by neutrophil granulocytes has been examined using a method which facilitates a precise in vitro evaluation of the phagocytic and bactericidal activities of human polymorphonuclear leucocytes. The bactericidal activity of the granulocytes(More)
Homogenated stratum coreum, callus and psoriatic scales were extracted with (1) phenol water (PW) and (2) the combined use of trypsin digestion and phenol water extraction (TPW). The serological properties of the various preparations obtained were compared, using indirect haemagglutination, absorption and inhibition tests. The PW and TPW water phases(More)
The level of Fc receptor rosette-forming lymphocytes (Fc-RFL) was examined in spleen and lymph node cell suspension from neonatal DA and BN rats inoculated within 24 hr of birth with either allogeneic L (experimental) or syngeneic (control) lymphoid cells. In addition, these levels were compared to fetal and neonatal animals that received no injection. The(More)
