3.1 Anaphylactic symptoms emerging in sensitized animals challenged by ovalbumin or cattle albumin
After challenge with ovalbumin or cattle albumin，the two model groups expressed typical clinical symptoms of anaphylaxis，for example sneezing，rubbing，and death，whereas the control group had no active systemic anaphylaxis symptoms(ASA)(Table 1).Because three guinea pigs died in each model groups after challenge，only 30 serum samples were obtained for metabolomic analysis.
