| Popis: | Lung mucociliary clearance (LMC) depends on age and it is adversely affected by cigarette smoking. When using the radioaerosol technique for measuring LMC the initial site of deposition of the radioaerosol within the lungs affects its rate of removal. Whether there is a difference in gender for LMC is still an open question. Forty-one (20 female, 21 male) healthy, non-smoking subjects had their lung mucociliary clearance measured using an objective, non-invasive radioaerosol technique. The male and female groups were closely matched for initial distribution of the radioaerosol. There was no statistical significant difference between males and females in the rate of clearance of inhaled radioaerosol over a 6 h observation period. When comparing the LMC of two groups although it is important to match them for age, smoking habits and initial topographical distribution of the tracer radioaerosol it does not seem essential to also match the two groups for gender. |
