Maturational changes in the intensity latency relation of the brainstem auditory evoked potentials in humans.
The effects of stimulus intensity variation on brainstem auditory evoked potentials have been studied on 111 preterm, 36 fullterm neonates and 50 adults. When intensity decreases the lengthening of latencies is greater in preterm neonates. This effect is clearer with wave I than waves III and V and suggests an immaturity of the basal part of the human cochlea in preterm neonates.

Experimental study of collagen as eardrum graft support in dogs.
This experimental study involving dogs tested type IV human collagen as a biomaterial for use in the tympanic membrane reconstruction. A loss of substance was induced for the two tympanic membranes, and a type IV collagen graft made to one side. The kinetics of receiver fibroblast colonisation of the graft, as well as in the case of resorption, were studied. Anatomopathological examination revealed the process of reconstitution. This animal study prepares the way for studies on man.
