[Dysphagia] effects of barium on saliva production

[Sabrina.Gurd at lhsc.on.ca (Sabrina Gurd)]

Hello all, 

Does anyone know anything about the effects of barium on saliva
production? I've done a cursory literature search on the subject and
have come up empty-handed. I would like to know if the production of
saliva is altered in any way with po intake of barium (in normals and/or
other populations), as this could obviously have a significant impact on
interpreting MBS/VFSS data. 

Thanks for any help, 

SG
