[Quantification (by nomograms) of physiopathological parameters in an experimental model of passive anaphylaxis caused by immune complexes].
Pharmacological changes in a model of passive anaphylaxis by immune complexes in mice have been studied. The results have been evaluated by nomograms to overcome the difficulties observed when using classical criteria as 50% lethal dosis or 50% infective dosis in experimental models which do not allow serial dilutions of the reagents. Mean lethal time, maximal pathogenic capacity and relative survival time can be easily determined, allowing the comparison of the immunopharmacologic protection for each administration schedule. By these criteria, we have observed a different degree of anaphylactic reaction depending on the genetic background of the hosts as well as a protection against anaphylactic shock using the antiserotoninic cyproheptadine and, to a lesser extent, by the platelet antiaggregant ticlopidine.
