Abstract

Bronchial morphometry has been the object of great interest in the past few years. A recent investigation whowed poor correlation between the Reid Index and gland area determinations by a variety of methods. In the present study, gland/wall ratio (Reid Index) was compared with estimation of total, inner, and outer gland areas by the card-weighing method. Correlation was in general poor but unexpectedly presented a lower Coefficient Index for glands located internal than for those located external to the cartilage. A new proposed index of gland/lumen ratio has the advantage of including information not only about the glands in their entirety, but also the cross-sectional luminal area of bronchi.
