The pattern of urinary acid mucopoly-saccharide excretion before, during and after fresh plasma infusions to five patients with mucopolysaccharidosis has been studied using the cetylpyridinium chloride (CPC) precipitation methcd. In all of the patients (three cases with Hurler syndrome, one case with Scheie syndrome and one case with Morquio syndrome), the results obtained were summarized as follows: 1) The plasma infusions were followed by a transient decreased urinary excretion of acid mucopolysaccharides. 2) Furthermore, the infusions were followed by an increased excretion of the non-CPC-precipitates. 3) Ratios of acid mucopolysaccharides to non-CPC-precipitates showed the lowest values on the third or fourth day after plasma infusions. 4) It is suggested that plasma infusions did not modify the course of the patients with mucopolysaccharidosis.
