Oral challenge and monitoring of anaphylaxis.
Mice were challenged orally with 45 mg of cashew protein extract
(protein equivalent). Anaphylactic reactions were characterized by a
drop in body temperature and the occurrence of clinical symptoms. Body
temperature was measured before challenge and every 5 minutes for 60
minutes following challenge using subcutaneous transponders (Plexx).
Clinical symptoms were recorded following the same frequency.Figure 2 : diarrhea was scored as followed: 0, no diarrhea; 1,
soft but well-shaped stool; 2, soft and unformed stool; 3, one episode
of diarrhea; 4, at least two episodes of diarrhea. Figure 5 :

nose scratching and ruffled fur; 2, mouse and eyes swelling, pilar
erectus and reduced activity; 3, difficulty breathing, mouth cyanosis
