Study Summary
Smoking damages the airway epithelium. The major mechanism by which this is done is by molecules called free radicals. Our body attempts to deal with these damaging molecules in two ways. One mechanism is via the presence of protective anti-oxidant vitamins and the other is via proteins that are produced by the body to convert free radicals to safer, less reactive molecules. Vitamins in our diet play a significant role in antioxidant defenses by directly neutralizing the damaging free-radicals and by providing co-factors to cellular proteins that neutralize the free radicals. This project is designed to look at the effects of giving individuals supplemental vitamins to see if it improves their defenses against oxidant insults. The investigators plan to look at the effects of these supplements over a 30 day period and monitor the effects by measuring vitamin levels in the blood and in the lung, and by measuring the response of cells in the lung through the increase or decrease in expression of genes responsive to oxidants. To participate in this protocol, the research subject should first be enrolled in Weill-IRB protocol #0005004439 entitled "Evaluation of the Lungs of Normal (Smokers, Ex-smokers, Non-Smokers) Individuals with Segmental Bronchopulmonary Lung Lavage, Bronchial Brushing, and Bronchial Wall Biopsy", fulfilling the inclusion/exclusion criteria of that protocol. They will be invited to participate in this Vitamin protocol only if they meet the additional inclusion/exclusion criteria of this protocol.
