[Effect of a visit in an eradication environment on reactivity to mites in the respiratory mucus].
33 asthmatic children, stabilised and allergic to mites on a long-term stay at Font-Romeu, were included in a protocol that was intended to show the effect of stay in an environment of natural eradication on the reactivity of the nasal mucosae. 3 groups were formed: A. To receive every day several microgrammes of mites on the nasal mucosae, lasting one month P. Physiological saline T. Left untreated. The reactivity was measured before the test, after one month, then after about another month during which each group was left untreated. The reactivity remained stable in A and T, and reduced in P. The indications were: 1. That the mites (the stay in the infested environment) augmented the reactivity. 2. In the eradication environment it decreased then stabilised itself at a basal level. 3. It then decreased again, due to the effect of the saline.
