A study by perfusion techniques of the absorption abnormalities in the jejunum in adult coeliac disease.

be a process separate from absorption (Hendrix & Bayless, 1970), this interpretation is of some interest. None of this invalidates the general conclusions reached by Dr Russell and his associates, including their important observation that clinical remission is not synonymous with functional improvement. It does point to the caution that must be used in comparing the results of perfusion studies which may differ significantly in details of technique-and perhaps for the need for perfusionists to reach some measure of agreement on standard experimental procedures.
