Fig. 1. Time course of measurements and treatment protocol according to the drug used for resuscitation: epinephrine and/or arginine vasopressin (AVP) in the different groups (n = 6/group). Pre-anaphylactic shock values were recorded after randomization of the four groups of rats and before shock induction (T0 − 5 min). Time 0 (T0) corresponds to the injection of ovalbumin. Treatment was started 5 min after ovalbumin injection (T0 + 5 min).
