Example Sentences:

(2) Possible reasons for the previous discrepancies between direct and isotopic methods are discussed, as are the effects of protein binding, sample handling, and storage conditions on oxalate values in plasma.
(3) The blockage of the tubular system by the calcium oxalate deposits leads to a temporary reversible increase in serum urea and serum creatinine.
(4) The differences in the amounts of rapidly releasable calcium were attributed to different kinetics of calcium phosphate and calcium oxalate dissolution.
(5) Cholestyramine known to reduce oxalate excretion in hyperuxaluria associated with ileal resection did not directly affect absorption of oxalic acid, but decreased the enhanced absorption of oxalic acid induced by bile acids.
(6) Cellulose phosphate greatly reduced phosphate crystals but resulted in a large increase in small oxalate crystals but without change in the incidence of aggregation of oxalate crystals.
