Resumen

Se ha estudiado la DLCOSB en 83 mineros con neumoconiosis simple y 46 sin neumoconiosis radiológica, todos ellos sin obstrucción de vías aéreas (Tiffeneau normal). Los primeros tenían valores de DLCOSB significativamente más bajos que un grupo control, si bien las diferencias eran pequeñas. Los segundos tenían también valores ligeramente más bajos pero las diferencias no llegaban a ser significativas.

Se encontró en el grupo de neumoconiosis simple una correlación débil (r: 0,23) pero significativa (p < 0,05) entre DL COSB y CV. % normal. No había en cambio córrelación entre DLCOSB y profusión o tipo de nodulación.

Summary

The authors have studied the DLCOSB in 83 miners with simple pneumoconiosis and in 46 miners without radiological pneumoconiosis, none of whom presented obstruction of the airways (Tiffeneau normal). The first group had DLCOSB valúes significantly lower than the control group, although the differences were small. The second groups also had valúes slightly lower but the differences were not significant.

In the group with simple pneumononiosis a weak (r: 0,23) but significant (p 0,05) correlation was found between DLCOSB and C.V. % normal. On the other hand there was no correlation between DLCOSB and profusión of type of nodulation.
