This study was undertaken to develop a subacute murine model for predicting occurrence of systemic anaphylaxis and to evaluate efficacy of various immunological parameters as the monitoring indices for the occurrence of anaphyalxis. The murice anaphyalxis model was developed through intraperitoneally sensitizing 100㎍ ovalbumin (OVA) in the presence of 1mg alum and 300ng cholera toxin twice a week interval followed by challenging 500㎍ OVA intravenously. Typical anaphylaxis symptoms were demonstrated at the both BALB/c mice, a strain prone to type-2 response, and C57BL/6 mice, a strain prone to type-1 response. Level of plasma histamine was approximately 50-fold or 30-fold higher in the mice sensitized with OVA than the mice sensitized with alum plus cholera toxin or the saline-treated mice after OVA challenge, respectively. Sensitization and challenge with OVA significantly enhanced plasma leukotriene B₄levels but not IgE levels in comparison with the control mice, which indicated the role of leukotriene B₄for progression of anaphyalxis. Furthermore, among mice suffered from anaphylaxis, levels of OVA-specific IgG1 were significantly higher in the BALB/c mice than in the C57BL/6 mice, which implied the genetic susceptibility for the induction of systemic anaphylasix. Conclusively, simultaneous evaluation of histamine, leukotriene B₄, and allergen-specific IgG isotype may serve as more efficient monitoring tool for vaccine-related anaphyalxis.
