AbstractSixty-four cases of infants ranging from 4 to 24 months of age (fed on milk) who suffered from Recurrent Obstructive Bronchopathy and a group of 10 healthy children were studied during 6 months (from May to October, 1984) in order to evaluate the incidence of the microaspiration phenomenon. This was done by means of a quick, easy and very cheap cytological method which etiologically diagnoses the microaspiration through fat elements phagocitized by the alveolar macrophages. They were evident in two different ways: 1) a new method of stained cellulae of a better morphological fidelity. 2) a larger quantity of exploratory smears from each patient which allowed an easier elimination of positive falses and a better individuation of negative falses. The data obtained by the technic were statistically processed using the significance of Chi or Khy square test, so as to make an exploratory-descriptive study of the method through the comparison of the averages obtained from the samples, smears and macrophages.
