Effects of kerosene on airway sensitization to egg albumin in guinea pig

We undertook a study to determine if pre-exposure to kerosene smoke enhances airway sensitization to egg albumin in the guinea pig. Kerosene vapor inhalation for 15 days, 1 hour daily, in similar conditions to which some housewives who use kerosene as cooking fuel are exposed elicited tracheal damage characterized by signs of dysplasia and inflammatory infiltrate. When these animals were exposed to egg albumin aerosol there was an increase in the antialbumin antibody blood titer and an increased response to egg albumin in the isolated tracheal preparation (Schultz-Dale reaction), We conclude that the airway damage elicited by inhalation of kerosene vapor increase antigen absorption and thereby antibody formation.
