[Evaluation of total serum complement by radial immunohemolysis in allergic asthma].

The role of the complement system in human allergic asthma has been studied by serum complement evaluation by radial immuno-hemolysis. Various groups were tested: 50 normal subjects, 49 allergic patients, 6 pollen sensible patients during and after pollinic season. Complement was evaluated during and after allergen challenge (11 patients). No significative variations were established neither during the challenge nor after (15 mn, 45 mn, 1 h).
