[Evaluation of the alternative approach to complement activation using C3-dependent adhesion].

The authors suggest a method of functional probing of the complement alternative cascade, the jist of it being analysis of the neutrophil adhesion to sephadex granules treated with serum or another complement-containing substrate. The advantages of the method are analyzed, and the range of its application suggested.

[Immunological reactivity to the products of normal microflora. IV. Antibodies to common species-specific pneumococcal antigens in the human spectrum of antibacterial antibodies].

Normal human serum antibodies to the protein complex more than 20 common (species-specific) STr. Pneumoniae antigens have been studied. In commercial lots of gamma globulin, manufactured during the last 8 years, antibodies to 9 pneumococcal antigens have been detected.
