A method of determining the presence of epithelial lesions is provided wherein a sample of a body of fluid taken from an epithelial region suspected to have said lesions is tested for the presence of a proteolytic activity. The lesion is then treated by applying a therapeutically effective amount of a proteinase inhibitor in the form of a physiologically acceptable preparation, a pharmaceutical preparation of aprotinin being particularly preferred. A method for detecting allergic sensitivity is also disclosed.
