Behavioural correlates of conditioned ventilatory responses to hypoxia in rats.

To examine the possible contribution of behavioural arousal to ventilatory conditioning, we performed a differential conditioning experiment using two odours as the paired conditioned stimulus (CS + ) and unpaired conditioned stimulus (CS-) and a hypoxic mixture (7.5% O2) as the unconditioned stimulus (US) in 24 adult male rats. Vanillin was the CS + and rose the CS - in half the rats, and vice versa in the other half.

[Isolated mucosal ulcers disclosing idiopathic hypereosinophilic syndrome].

Introduction: Idiopathic hypereosinophilic syndrome is an uncommon disease often associated with diverse non-specific skin manifestations. Mucosal ulcerations suggest a myeloproliferative from with poor prognosis due to possible progression to malignant hemopathy or visceral complications.

Case Report: A 28-year-old man presented idiopathic hypereosinophilia with isolated mucosal ulcerations involving the buccal and genital areas.
